- Abstract
Background Methods Results Conclusion Surgical bariatric interventions, while highly effective, can be associated with post‐operative esophageal symptoms, gastroesophageal reflux disease and esophageal dysmotility. Whether pre‐operative physiology impacts this risk is unknown, in part because expected values on esophageal manometry in patients with obesity are not well understood. This study seeks to establish normative values on esophageal high resolution manometry (HRM) and the prevalence of esophageal dysmotility in the asymptomatic patient with obesity.This retrospective study included adult patients with body mass index (BMI) ≥35 kg m−2 without esophageal symptoms undergoing preoperative bariatric surgical evaluation, including HRM, at a single tertiary care center between February, 2019 and February, 2020.Of 104 asymptomatic patients with obesity, HRM identified normal esophageal motility in 94 (90.4%) with the remaining 10 having ineffective esophageal motility (3.8%), manometric esophagogastric junction outflow obstruction (3.8%), distal esophageal spasm (1.0%), and hypercontractile esophagus (1.0%). Mean of median lower esophageal sphincter integrated relaxation pressure (LES IRP) was 10.6 mmHg supine (95th percentile 21.5 mmHg) and 8.5 mmHg upright (95th percentile 21.3 mmHg). 86% of patients had intragastric pressure above 8 mmHg. Mean of mean distal contractile integral (DCI) was 2261.6 mmHg cm s−1 (95th percentile 5889.5 mmHg cm s−1).The vast majority of asymptomatic patients with obesity had normal manometry. LES IRP and DCI were higher than that observed in non‐obese cohorts. Additionally, BMI correlated to increased intragastric pressure. These data suggest that normative values in patients with obesity should be adjusted to prevent overdiagnosis of EGJOO or hypercontractile esophagus. [ABSTRACT FROM AUTHOR]

Objectives Methods Results Conclusion Early identification of patients needing hospital‐specific interventional care (HIC) following endoscopic treatment is valuable for optimizing postoperative hospital stays. We aimed to develop and validate a risk‐scoring system for predicting HIC in patients who underwent peroral endoscopic myotomy (POEM).This study included patients with esophageal motility disorders who underwent POEM at our hospital between April 2015 and March 2023. HIC was defined as any of the following situations: fasting for gastrointestinal rest to manage adverse events (AEs); intravenous administration of medications such as antibiotics and blood transfusion; endoscopic, radiologic, and surgical interventions; intensive care unit management; or other life‐threatening events. A risk‐scoring system for predicting HIC after postoperative day (POD) 1 was developed using multivariable logistic regression and was internally validated using bootstrapping and decision curve analysis.Of the 589 patients, 50 (8.5%) experienced HIC after POD1. Risk scores were assigned for four factors as follows: age (0 points for <70 years, 1 point for 70–79 years, 2 points for ≥80 years), preoperative prognostic nutritional index (0 points for >45, 1 point for 40–45, 4 points for <40), postoperative surgical site AEs on second‐look endoscopy (7 points), and postoperative pneumonia on chest radiography (6 points). The discriminative ability (concordance statistics, 0.85; 95% confidence interval, 0.78–0.91) and calibration (slope 1.00; 0.74–1.28) were satisfactory. The decision curve analysis demonstrated its clinical usefulness.This risk‐scoring system can predict the HIC after POD1 and provide useful information for determining discharge.

Background Methods Key Results Conclusions & Inferences Functional lumen imaging probe (FLIP) panometry assesses esophageal motility in response to controlled volumetric distension. This study aimed to describe the physiomechanical states of the lower esophageal sphincter (LES) in response to serial filling/emptying regimes for esophageal motility disorders.Fourty‐five patients with absent contractile response on FLIP and diagnoses of normal motility (n = 6), ineffective esophageal motility (IEM; n = 8), scleroderma (SSc; n = 10), or nonspastic achalasia (n = 21) were included, as were 20 patient controls with normal motility on FLIP and manometry. LES diameter and pressure were measured after stepwise FLIP filling at 60 mL, 70 mL, and emptying to 60 mL with relative changes used to define physiomechanical states.Passive dilatation after FLIP filling occurred in 63/65 (97%) patients among all diagnoses. After FLIP emptying, passive shortening occurred in 12/14 (86%) normal motility/IEM, 10/10 (100%) SSc, 9/21(43%) achalasia, and 16/20 (80%) controls, with auxotonic relaxation seen in 2/14 (14%) normal motility/IEM, 12/21 (57%) achalasia, and 4/20 (20%) controls. After achalasia treatment (LES myotomy), 21/21 (100%) achalasia had passive shortening after FLIP emptying.Physiomechanical states of the LES can be determined via response to FLIP filling and emptying regimes. While passive shortening was the general response to FLIP emptying, auxotonic relaxation was observed in achalasia, which was disrupted by LES myotomy. Further investigation is warranted into the clinical impact on diagnosis and treatment of esophageal motility disorders. [ABSTRACT FROM AUTHOR]

Background Methods Key Results Conclusions and Inferences The diagnosis of small bowel motility disorders is performed by manometric evaluation of the contractile patterns of the small intestine. Conventional intestinal manometry systems include few pressure sensors at relatively long intervals. We have recently shown that high‐resolution jejunal manometry, with multiple closely spaced recording sites, allows the analysis of propagation patterns of intestinal motility in healthy subjects that cannot be detected with conventional manometry. The objective of this pilot study was to explore the feasibility and diagnostic value of high‐resolution intestinal manometry in patients with suspected small bowel dysmotility.Prospective pilot study evaluating intestinal motility patterns in 16 consecutive patients (16–61 years; 11 women) with severe, chronic digestive symptoms referred for the evaluation of intestinal motility and in 18 healthy controls (21–38 years; 8 women). A 36‐channel high‐resolution manometry catheter was orally placed under radiological guidance in the jejunum. Intestinal motility was continuously recorded for 3 h fasting and 2 h after a 450 kcal meal. The manometric recordings were analyzed in two formats: (a) with the high‐resolution data from 34 channels and (b) showing only the recordings from 5 channels separated by 7 cm intervals, mimicking a conventional manometry recording.In the analysis mimicking conventional manometry, abnormal motility criteria were detected in six patients and in no healthy subject [bursts (n = 3), postprandial minute rhythm (n = 1) and myopathic pattern (n = 2)]. These classical dysmotility criteria were also detected by high‐resolution manometry. High‐resolution analysis detected one or more abnormal findings in seven additional patients that were not observed in any healthy subject, specifically: (a) abnormal propagation of Phase III (n = 3); (b) reduced propagated activity during Fasting Phase II (n = 4); (c) increased propagated activity during Fasting Phase II and postprandial phase (n = 1).This pilot study suggests that high‐resolution intestinal manometry may improve the sensitivity of conventional manometry in the detection of intestinal motor dysfunction.

- Abstract
Background/Objective: Multiple system atrophy (MSA) is often associated with dysphagia and esophageal dysmotility (ED). However, ED in patients with MSA is poorly understood. To assess the relationship between ED, dysphagia, and other clinical findings in such patients and investigate the details of ED in MSA using high-resolution manometry (HRM). Methods: Patients from The University of Tokyo Hospital with MSA who underwent swallowing examinations, esophagography, and HRM between 2017 and 2022 were enrolled. A retrospective chart review of patients' backgrounds, swallowing function, and esophageal motility was performed. ED was evaluated using the Chicago Classification version 4.0. Results: Seventy-four patients with MSA were identified. The median age was 64 years, 48 patients (65%) were male, and the cerebellar variant type was predominant (69%). Abnormal upper esophageal sphincter (UES) resting pressure was observed in 34 patients (46%) and intraesophageal stasis in 65 (88%). High-severity MSA was a risk factor for developing dysphagia, vocal fold movement impairment, and abnormal UES function (p < 0.05). However, no overt clinical risk factors for ED were identified. Various types of ED were detected using HRM, and ineffective esophageal motility was the most frequent disorder. Conclusions: ED is a common occurrence in patients with MSA. Although a high-severity MSA may be a risk factor for developing dysphagia and vocal fold motion impairment, ED can occur regardless of clinical severity. Since ED is rarely detected based on subjective symptoms, careful evaluation of esophageal motility by esophagography or HRM is warranted in patients with MSA. [ABSTRACT FROM AUTHOR]

Our prior study reveals that the distension-contraction profiles using high-resolution manometry impedance recordings can distinguish patients with dysphagia symptom but normal esophageal function testing ("functional dysphagia") from control subjects. The aim of this study was to determine the diagnostic value of the recording protocol used in our prior studies (10-mL swallows with subjects in the Trendelenburg position) against the standard clinical protocol (5-mL swallows with subjects in the supine position). We used advanced machine learning techniques and robust metrics for classification purposes. Studies were performed on 30 healthy subjects and 30 patients with functional dysphagia. A custom-built software was used to extract the relevant distension-contraction features of esophageal peristalsis. Ensemble methods, i.e., gradient boost, support vector machines (SVMs), and logit boost, were used as the primary machine learning algorithms. Although the individual contraction features were marginally different between the two groups, the distension features of peristalsis were significantly different. The receiver operating characteristic (ROC) curve values for the standard recording protocol and the distension features ranged from 0.74 to 0.82; they were significantly better for the protocol used in our prior studies, ranging from 0.81 to 0.91. The ROC curve values using three machine learning algorithms were far superior for the distension than the contraction features of esophageal peristalsis, revealing a value of 0.95 for the SVM algorithm. Current patient classification for esophageal motility disorders, based on the contraction phase of peristalsis, ignores a large number of patients who have an abnormality in the distension phase of peristalsis. Distension-contraction plots should be the standard for assessing esophageal peristalsis in clinical practice. NEW & NOTEWORTHY: Our findings underscore the superiority of distension features over contraction metrics in diagnosing esophageal dysfunctions. By leveraging state-of-the-art machine learning techniques, our study highlights the diagnostic potential of distension-contraction plots of peristalsis. Implementation of these plots could significantly enhance the accuracy of identifying patients with esophageal motor disorders, advocating for their adoption as the standard in clinical practice.

Background: Age‐related changes in the gastrointestinal system are common and may be influenced by physiological aging processes. To date, a comprehensive analysis of esophageal motor disorders in patients belonging to various age groups has not been adequately reported. Methods: We conducted a retrospective assessment of high‐resolution manometry (HRM) studies in a multicenter setting. HRM parameters were evaluated according to the Chicago Classification version 4.0. Epidemiological, demographic, clinical data, and main manometric parameters, were collected at the time of the examination. Age groups were categorized as early adulthood (<35 years), early middle‐age (35–49 years), late middle‐age (50–64 years), and late adulthood (≥65 years). Results: Overall, 1341 patients (632, 47.0% male) were included with a median age of 55 years. Late adulthood patients reported more frequently dysphagia (35.2%) than early adulthood patients (24.0%, p = 0.035), early middle‐age patients (21.0%, p < 0.0001), and late middle‐aged patients (22.7%, p < 0.0001). Esophagogastric junction outflow obstruction was more prevalent in late adulthood (16.7%) than in early adulthood (6.1%, p = 0.003), and in early middle‐age (8.1%, p = 0.001). Patients with normal esophageal motility were significantly younger (52.0 years) than patients with hypercontractile esophagus (61.5 years), type III achalasia (59.6 years), esophagogastric junction outflow obstruction (59.4 years), absent contractility (57.2 years), and distal esophageal spasm (57.0 years), in multivariate model (p < 0.0001). Conclusion: The rate of esophageal motor disorders is higher in older patients, in particular esophagogastric junction outflow obstruction and hypercontractile esophagus. Future prospective studies are necessary to confirm our results and to find tailored strategies to improve clinical outcomes. [ABSTRACT FROM AUTHOR]

Background: Longitudinal incision is the commonly used incision for entry into the submucosal space during peroral endoscopic myotomy (POEM) for esophageal motility disorders. Transverse incision is another alternative for entry and retrospective data suggest it has less operative time and chance of gas-related events. Methods: This was a single-center, randomized trial conducted at a tertiary care hospital. Patients undergoing POEM for esophageal motility disorders were randomized into group A (longitudinal incision) and group B (transverse incision). The primary objective was to compare the time needed for entry into the submucosal space. The secondary objectives were to compare the time needed to close the incision, number of clips required to close the incision, and development of gas-related events. The sample size was calculated as for a non-inferiority design using Kelsey method. Results: Sixty patients were randomized (30 in each group). On comparing the 2 types of incisions, there was no difference in entry time [3 (2, 5) vs 2 (1.75, 5) min, p = 0.399], closure time [7 (4, 13.5) vs 9 (6.75, 19) min, p = 0.155], and number of clips needed for closure [4 (4, 6) vs 5 (4, 7), p = 0.156]. Additionally, the gas-related events were comparable between the 2 groups (capnoperitoneum needing aspiration—5 vs 2, p = 0.228, and development of subcutaneous emphysema—3 vs 1, p = 0.301). Conclusion: This randomized trial shows comparable entry time, closure time, number of clips needed to close the incision, and gas-related events between longitudinal and transverse incisions. Registration number: CTRI/2021/08/035829. [ABSTRACT FROM AUTHOR]

Achalasia is a rare esophageal motility disorder characterized by nonrelaxation of the lower esophageal sphincter. Laparoscopic Heller myotomy (LHM) is the gold standard treatment for achalasia. Peroral endoscopic myotomy (POEM), a less invasive treatment, is performed extensively, and the selection of the intervention method remains debatable to date. In addition to the availability of extensive studies on short‐term outcomes, recent studies on the long‐term outcomes of LHM and POEM have shown similar clinical success after 5 y of follow‐up. However, gastroesophageal reflux disease (GERD) was more common in patients who had undergone POEM than in those who had undergone LHM. Moreover, existing studies have compared treatment outcomes in various disease states. Some studies have suggested that POEM is superior to LHM for patients with type III achalasia because POEM allows for a longer myotomy. Research on treatment for sigmoid types is currently in progress. However, the long‐term results comparing LHD and POEM are insufficient, and the best treatment remains controversial. Further research is needed, and treatment options should be discussed with patients and tailored to their individual needs and pathologies. [ABSTRACT FROM AUTHOR]

Lower esophageal sphincter (LES) pathophysiology has been established in gastroesophageal reflux disease (GERD); however, less is understood regarding the role the upper esophageal sphincter (UES) plays in preventing laryngopharynphageal reflux. Sustained UES basal pressure prevents reflux into the pharynx while allowing relaxation during ingestion. We investigate whether GERD influences UES function via HRM and pH Impedance testing. A retrospective analysis of 318 patients who underwent high‐resolution manometry with trans‐nasally placed manometric catheter and 24‐h multichannel intraluminal impedance pH monitoring. One hundred and forty‐seven patients met Lyon consensus criteria for GERD based on acid exposure time >6%. The most common chief concern was heartburn or reflux, present in 59% of these patients. Upper esophageal sphincter basal and residual pressures were not significantly different between patients with GERD when compared to those without GERD, including a subanalysis of patients with extraesophageal symptoms. The LES basal and residual pressures, DCI and MNBI are statistically lower in patients with pathologic GERD. HRM and pH Impedance testing demonstrates no difference in UES basal and residual pressures based on pH diagnosis of GERD. We redemonstrate the association with hypotonic LES, diminished DCI and MNBI with GERD. [ABSTRACT FROM AUTHOR]

Data are limited regarding gastrointestinal motility disturbance in disorders of gut-brain interaction (DGBI). This study aimed to characterize antroduodenal motor alterations in patients with high-resolution antroduodenal manometry (HR-ADM). HR-ADM was performed in patients with severe DGBI and compared with healthy volunteers (HV). HR-ADM used a commercially available probe composed of 36 electronic sensors spaced 1 cm apart and positioned across the pylorus. Antral and duodenal motor high-resolution profiles were analyzed, based on the frequency, amplitude, and contractile integral/sensor (CI/s) calculated for each phase of the migrating motor complex (MMC). Eighteen HV and 64 patients were investigated, 10 with irritable bowel syndrome (IBS), 24 with functional dyspepsia (FD), 15 with overlap IBS-FD, and 15 with other DGBI. Compared with HV, patients had a lower frequency of phase II duodenal contractions (27 vs. 51 per hour; P ¼ 0.002) and a lower duodenal phase II contraction amplitude (70 vs. 100 mmHg; P ¼ 0.01), resulting in a lower CI/s of phase II (833 vs. 1,901 mmHg·cm·s; P < 0.001) in the duodenum. In addition, the frequency of phase II propagated antroduodenal contractions was lower (5 vs. 11 per hour; P < 0.001) in patients compared with HV. Interestingly, the antral CI/s of phase III was decreased in FD patients but not in IBS patients. Patients with severe DGBI display alterations in antral and intestinal motility assessed by commercially available HR-ADM. Whether these alterations may explain symptom profiles in such patients remains to be confirmed (NCT04918329 and NCT01519180). NEW & NOTEWORTHY Gastrointestinal dysmotility has been assessed poorly in disorders of gut-brain interaction (DGBI), especially with high-resolution antroduodenal manometry. Plots of DGBI patients showed lower duodenal contractions during phase II regarding amplitude, frequency, and contractile integral/sensor (CI/s) compared with healthy volunteers. A lower frequency of propagated antroduodenal contractions was also reported. Finally, antral CI/s was lower in patients with functional dyspepsia during phase III. Further studies are needed to assess the clinical significance of these alterations. [ABSTRACT FROM AUTHOR]

Background: Esophageal motility disorders can be diagnosed by either high‐resolution manometry (HRM) or the functional lumen imaging probe (FLIP) but there is no systematic approach to synergize the measurements of these modalities or to improve the diagnostic metrics that have been developed to analyze them. This work aimed to devise a formal approach to bridge the gap between diagnoses inferred from HRM and FLIP measurements using deep learning and mechanics. Methods: The "mechanical health" of the esophagus was analyzed in 740 subjects including a spectrum of motility disorder patients and normal subjects. The mechanical health was quantified through a set of parameters including wall stiffness, active relaxation, and contraction pattern. These parameters were used by a variational autoencoder to generate a parameter space called virtual disease landscape (VDL). Finally, probabilities were assigned to each point (subject) on the VDL through linear discriminant analysis (LDA), which in turn was used to compare with FLIP and HRM diagnoses. Results: Subjects clustered into different regions of the VDL with their location relative to each other (and normal) defined by the type and severity of dysfunction. The two major categories that separated best on the VDL were subjects with normal esophagogastric junction (EGJ) opening and those with EGJ obstruction. Both HRM and FLIP diagnoses correlated well within these two groups. Conclusion: Mechanics‐based parameters effectively estimated esophageal health using FLIP measurements to position subjects in a 3‐D VDL that segregated subjects in good alignment with motility diagnoses gleaned from HRM and FLIP studies.

Background: High‐resolution esophageal manometry (HREM) is the gold standard test for esophageal motility disorders. Nasopharyngeal airway‐assisted insertion of the HREM catheter is a suggested salvage technique for failure from the inability to pass the catheter through the upper esophageal sphincter (UES). It has not been demonstrated that the nasopharyngeal airway improves procedural success rate. Methods: Patients undergoing HREM between March 2019 and March 2023 were evaluated. Chart review was conducted for patient factors and procedural success rates before and after use of nasopharyngeal airway. Patients from March 2019 to May 2021 did not have nasopharyngeal airway available and were compared to patients from May 2021 to March 2023 who had the nasopharyngeal airway available. Key Results: In total, 523 HREM studies were conducted; 234 occurred prior to nasopharyngeal airway availability, and 289 occurred with nasopharyngeal airway availability. There was no difference in HREM catheter UES intubation rates between periods when a nasopharyngeal airway attempt was considered procedural failure (85% vs. 85%, p = 0.9). Nasopharyngeal airway use after UES intubation failure lead to improved UES intubation rates (94% vs. 85%, p < 0.01). Thirty‐six patients that failed HREM catheter UES intubation had the procedure reattempted with a nasopharyngeal airway, 30 (83%) of which were successful. The nasopharyngeal airway assisted catheter UES intubation for failures attributed to nasal pain and hypersensitivity, gagging, coughing, and pharyngeal coiling. Conclusions & Inferences: Utilization of the nasopharyngeal airway increased rates of UES intubation. When HREM catheter placement through the UES fails, placement of a nasopharyngeal airway can be trialed to overcome patient procedural intolerance. [ABSTRACT FROM AUTHOR]

Esophageal manometry is utilized for the evaluation and classification of esophageal motility disorders. EndoFlip has been introduced as an adjunctive test to evaluate esophagogastric junction (EGJ) distensibility. Treatment options for achalasia and EGJ outflow obstruction (EGJOO) include pneumatic dilation, myotomy, and botulinum toxin. Recently, a therapeutic 30 mm hydrostatic balloon dilator (EsoFLIP, Medtronic, Minneapolis, MN, USA) has been introduced, which uses impedance planimetry technology like EndoFlip. We performed a systematic review to evaluate the safety and efficacy of EsoFLIP in the management of esophageal motility disorders. A systematic literature search was performed with Medline, Embase, Web of science, and Cochrane library databases from inception to November 2022 to identify studies utilizing EsoFLIP for management of esophageal motility disorders. Our primary outcome was clinical success, and secondary outcomes were adverse events. Eight observational studies including 222 patients met inclusion criteria. Diagnoses included achalasia (158), EGJOO (48), post-reflux surgery dysphagia (8), and achalasia-like disorder (8). All studies used 30 mm maximum balloon dilation except one which used 25 mm. The clinical success rate was 68.7%. Follow-up duration ranged from 1 week to a mean of 5.7 months. Perforation or tear occurred in four patients. EsoFLIP is a new therapeutic option for the management of achalasia and EGJOO and appears to be effective and safe. Future comparative studies with other therapeutic modalities are needed to understand its role in the management of esophageal motility disorders. [ABSTRACT FROM AUTHOR]

BARRETT'S esophagus , *ESOPHAGEAL varices , *EOSINOPHILIC esophagitis , *ESOPHAGOGASTRIC junction , *HIATAL hernia , *ESOPHAGEAL motility disorders - Abstract
In patients with dysphagia that is not explained by upper endoscopy, high-resolution esophageal manometry (HRM) is the next logical step in diagnostic testing. This study investigated predictors of failure to refer for HRM after an upper endoscopy that was performed for but did not explain dysphagia. This was a retrospective cohort study of patients >18 years of age who underwent esophagogastroduodenoscopy (EGD) for dysphagia from 2015 to 2021. Patients with EGD findings that explained dysphagia (e.g. esophageal mass, eosinophilic esophagitis, Schatzki ring, etc.) were excluded from the main analyses. The primary outcome was failure to refer for HRM within 1 year of the index non-diagnostic EGD. We also investigated delayed referral for HRM, defined as HRM performed after the median. Multivariable logistic regression modeling was used to identify risk factors that independently predicted failure to refer for HRM, conditioned on the providing endoscopist. Among 2132 patients who underwent EGD for dysphagia, 1240 (58.2%) did not have findings to explain dysphagia on the index EGD. Of these 1240 patients, 148 (11.9%) underwent HRM within 1 year of index EGD. Endoscopic findings (e.g. hiatal hernia, tortuous esophagus, Barrett's esophagus, surgically altered anatomy not involving the gastroesophageal junction, and esophageal varices) perceived to explain dysphagia were independently associated with failure to refer for HRM (adjusted odds ratio 0.45, 95% confidence interval 0.25–0.80). Of the 148 patients who underwent HRM within 1 year of index EGD, 29.7% were diagnosed with a disorder of esophagogastric junction outflow, 17.6% with a disorder of peristalsis, and 2.0% with both disorders of esophagogastric outflow and peristalsis. The diagnosis made by HRM was similar among those who had incidental EGD findings that were non-diagnostic for dysphagia compared with those who had completely normal EGD findings. Demographic factors including race/ethnicity, insurance type, and income were not associated with failure to refer for HRM or delayed HRM. Patients with dysphagia and endoscopic findings unrelated to dysphagia have a similar prevalence of esophageal motility disorders to those with normal endoscopic examinations, yet these patients are less likely to undergo HRM. Provider education is indicated to increase HRM referral in these patients. [ABSTRACT FROM AUTHOR]

Key Clinical Message: This case emphasizes the need for early recognition and accurate diagnosis of achalasia in young adults to avoid exacerbation of the condition and misdiagnosis as GERD. Patient outcomes and quality of life are greatly enhanced by suitable diagnostic techniques, appropriate therapy, interdisciplinary care, and comprehensive patient education along with frequent follow‐ups. Achalasia results from the degeneration of inhibitory ganglion cells within the esophageal myenteric plexus and the lower esophageal sphincter (LES), leading to a loss of inhibitory neurons and resulting in the absence of peristalsis with failure of LES relaxation. Its origins are multifactorial, potentially involving infections, autoimmune responses, and genetics, with equal incidence in males and females. The hallmark symptoms include progressive dysphagia for solids and liquids, along with regurgitation, heartburn, and non‐cardiac chest pain. A 22‐year‐old female patient initially diagnosed with gastroesophageal reflux disease (GERD) received proton pump inhibitors and antacid gel for persistent dysphagia and regurgitation. Subsequent tests including barium esophagogram and manometry indicated Type II Achalasia Cardia. The patient showed clinical improvement with relief of dysphagia, regurgitation, and heartburn symptoms after pneumatic balloon dilatation (PBD). She was advised to follow up after 6 months with upper gastrointestinal (UGI) endoscopy and manometry in the outpatient clinic for regular endoscopic surveillance as there is a risk of transformation to esophageal carcinoma. Diagnosing achalasia in young adults poses challenges due to its diverse presentation and resemblance to other esophageal disorders like GERD. Diagnosis relies on clinical symptoms and imaging studies such as barium esophagogram revealing a bird's beak appearance and esophageal manometry showing absent peristalsis. UGI endoscopy is needed to rule out malignancy. Treatment options include non‐surgical approaches like medication and Botox injections, as well as surgical methods such as pneumatic balloon dilation, laparoscopic Heller myotomy, and per‐oral endoscopic myotomy (POEM). The treatment options depend upon the patient's condition at presentation and their individual choices. This case report emphasizes that it is crucial to consider achalasia as a potential differential diagnosis in young adults with dysphagia, especially if conventional treatments for acid peptic disorder do not alleviate symptoms. Prompt diagnosis and appropriate management can lead to significant clinical improvement and better patient outcomes. [ABSTRACT FROM AUTHOR]

- Abstract
Background and Objectives: Achalasia has several treatment modalities. We aim to compare the efficacy and safety of laparoscopic Heller myotomy (LHM) with those of pneumatic dilatation (PD) in adult patients suffering from achalasia. Methods: We searched Cochrane CENTRAL, PubMed, Web of Science, SCOPUS and Embase for related clinical trials about patients suffering from achalasia. The quality appraisal and assessment of risk of bias were conducted with GRADE and Cochrane's risk of bias tool, respectively. Homogeneous and heterogeneous data was analyzed under fixed and random-effects models, respectively. Results: The pooled analysis of 10 studies showed that PD was associated with a higher rate of remission at three months, one year, three years and five years (RR = 1.25 [1.09, 1.42] (p = 0.001); RR = 1.13 [1.05, 1.20] (p = 0.0004); RR = 1.48 [1.19, 1.82] (p = 0.0003); RR = 1.49 [1.18, 1.89] (p = 0.001)), respectively. LHM was associated with lower number of cases suffering from adverse events, dysphagia and relapses (RR = 0.50 [0.25, 0.98] (p = 0.04); RR = 0.33 [0.16, 0.71] (p = 0.004); RR = 0.38 [0.15, 0.97] (p = 0.04)), respectively. There is no significant difference between both groups regarding the lower esophageal pressure, perforations, remission rate at two years, Eckardt score after one year and reflux. Conclusion: PD had higher remission rates than LHM at three months, one year and three years, but not at two years or five years. More research is needed to determine whether PD has a significant advantage over LHM in terms of long-term remission rates. [ABSTRACT FROM AUTHOR]

Gastroesophageal reflux disease (GERD), a prevalent clinical condition, is often attributed to aberrant esophageal motility, leading to gastric content reflux and associated symptoms or complications. The rising incidence of GERD presents an escalating healthcare challenge. Endoscopic and esophageal reflux monitoring can provide a basis for the diagnosis of patients with gastroesophageal reflux disease, but when the diagnostic basis is at an inconclusive value, some additional supportive evidence will be needed. Advanced technology is the key to improving patient diagnosis, accurate assessment, and the development of effective treatment strategies. High-resolution esophageal manometry (HREM) and endoscopic functional lumen imaging probe (EndoFLIP) represent the forefront of esophageal motility assessment. HREM, an evolution of traditional esophageal manometry, is considered the benchmark for identifying esophageal motility disorders. Its widespread application in esophageal dynamics research highlights its diagnostic significance. Concurrently, EndoFLIP's emerging clinical relevance is evident in diagnosing and guiding the treatment of coexisting esophageal motility issues. This review integrates contemporary research to delineate the contributions of HREM, EndoFLIP, and novel technologies in GERD. It examines their efficacy in facilitating an accurate diagnosis, differentiating similar gastrointestinal disorders, quantifying the extent of reflux, assessing the severity of the disease, forecasting patient responsiveness to proton pump inhibitor therapy, and guiding decisions for surgical interventions. The overarching aim is to deepen the understanding of GERD's underlying mechanisms and advance the formulation of holistic, efficacious treatment approaches. [ABSTRACT FROM AUTHOR]

Background/Aims: Ineffective esophageal motility (IEM) is common in patients with gastroesophageal reflux disease (GERD) and can be associated with poor esophageal contraction reserve on multiple rapid swallows. Alterations in the esophageal microbiome have been reported in GERD, but the relationship to presence or absence of contraction reserve in IEM patients has not been evaluated. We aim to investigate whether contraction reserve influences esophageal microbiome alterations in patients with GERD and IEM. Methods: We prospectively enrolled GERD patients with normal endoscopy and evaluated esophageal motility and contraction reserve with multiple rapid swallows during high-resolution manometry. The esophageal mucosa was biopsied for DNA extraction and 16S ribosomal RNA gene V3-V4 (Illumina)/full-length (Pacbio) amplicon sequencing analysis. Results: Among the 56 recruited patients, 20 had normal motility (NM), 19 had IEM with contraction reserve (IEM-R), and 17 had IEM without contraction reserve (IEM-NR). Esophageal microbiome analysis showed a significant decrease in microbial richness in patients with IEM-NR when compared to NM. The beta diversity revealed different microbiome profiles between patients with NM or IEM-R and IEM-NR (P = 0.037). Several esophageal bacterial taxa were characteristic in patients with IEM-NR, including reduced Prevotella spp. and Veillonella dispar, and enriched Fusobacterium nucleatum. In a microbiome-based random forest model for predicting IEM-NR, an area under the receiver operating characteristic curve of 0.81 was yielded. Conclusions: In symptomatic GERD patients with normal endoscopic findings, the esophageal microbiome differs based on contraction reserve among IEM. Absent contraction reserve appears to alter the physiology and microbiota of the esophagus. [ABSTRACT FROM AUTHOR]

Background: Disruption of external anal sphincter muscle (EAS) is an important factor in the multifactorial etiology of fecal incontinence (FI). Objectives: We categorize FI patients into four groups based on the location of lesion in neuromuscular circuitry of EAS to determine if there are differences with regards to fecal incontinence symptoms severity (FISI) score, age, BMI, obstetrical history, and anal sphincter muscle damage. Methods: Female patients (151) without any neurological symptoms, who had undergone high‐resolution manometry, anal sphincter EMG, and 3D ultrasound imaging of the anal sphincter were assessed. Patients were categorized into four groups: Group 1 (normal)—normal cough EMG (>10 μV), normal squeeze EMG (>10 μV), and normal anal squeeze pressure (>124 mmHg); Group 2 (cortical apraxia, i.e., poor cortical activation)—normal cough EMG, low squeeze EMG, and low anal squeeze pressure; Group 3 (muscle damage)—normal cough EMG, normal squeeze EMG, and low anal squeeze pressure; and Group 4 (pudendal nerve damage)—low cough EMG, low squeeze EMG, and low anal squeeze pressure. Results: The four patient groups were not different with regards to the patient's age, BMI, parity, and FISI scores. 3D ultrasound images of the anal sphincter complex revealed significant damage to the internal anal sphincter, external anal sphincter, and puborectalis muscles in all four groups. Conclusion: The FI patients are a heterogeneous group; majority of these patients have significant damage to the muscles of the anal sphincter complex. Whether biofeedback therapy response is different among different patient groups requires study. [ABSTRACT FROM AUTHOR]

The aim of this review is to provide an overview of per-oral endoscopic myotomy (POEM) and its utilization in non-achalasia disorders of the esophagus. POEM, a relatively novel endoscopic technique, involves submucosal tunneling to access esophageal muscle layers, enabling selective myotomy and mitigating the consequences of motor disorders of the esophagus. POEM is an effective treatment modality for diffuse esophageal spasm providing resolution of chest pain and dysphagia in a majority of patients who have refractory symptoms despite medical therapy. The results of POEM are more equivocal compared to esophagogastric junction outflow obstruction (EGJOO). POEM in EGJOO has been shown to have a 93% clinical success rate in 6 months. POEM appears to be more effective in motor disorders that affect the lower esophageal sphincter, such as EGJOO and opioid-induced esophageal dysfunction. While the current data for POEM in other entities such as DES and HE are positive, more supportive data are required to make POEM a consistent recommendation for patients. [ABSTRACT FROM AUTHOR]

After the evolution of Upper Gastrointestinal endoscopy in the modern era, the role of barium swallow as a primary modality of approaching towards dysphagia has been seeing a declining trend. However, the role of Barium swallow as a diagnostic tool is still pivotal in going towards finding out the causes of Dysphagia, particularly in motility disorders of the esophagus, extrinsic compressions of the esophagus etc. Barium swallow as a diagnostic tool isn't a substitute to Upper GI endoscopy but is complimentary instead.

INTRODUCTION: High-resolution manometry (HRM) and functional lumen imaging probe (FLIP) are primary and/or complementary diagnostic tools for the evaluation of esophageal motility. We aimed to assess the interrater agreement and accuracy of HRM and FLIP interpretations. METHODS: Esophageal motility specialists from multiple institutions completed the interpretation of 40 consecutive HRM and 40 FLIP studies. Interrater agreement was assessed using intraclass correlation coefficient (ICC) for continuous variables and Fleiss κ statistics for nominal variables. Accuracies of rater interpretation were assessed using the consensus of 3 experienced raters as the reference standard. RESULTS: Fifteen raters completed the HRM and FLIP studies. An excellent interrater agreement was seen in supine median integral relaxation pressure (ICC 0.96, 95% confidence interval 0.95-0.98), and a good agreement was seen with the assessment of esophagogastric junction (EGJ) outflow, peristalsis, and assignment of a Chicago Classification version 4.0 diagnosis using HRM (κ = 0.71, 0.75, and 0.70, respectively). An excellent interrater agreement for EGJ distensibility index and maximum diameter (0.91 [0.90-0.94], 0.92 [0.89-0.95]) was seen, and a moderate-to-good agreement was seen in the assignment of EGJ opening classification, contractile response pattern, and motility classification (κ = 0.68, 0.56, and 0.59, respectively) on FLIP. Rater accuracy for Chicago Classification version 4.0 diagnosis on HRM was 82% (95% confidence interval 78%-84%) and for motility diagnosis on FLIP Panometry was 78% (95% confidence interval 72%-81%). DISCUSSION: Our study demonstrates high levels of interrater agreement and accuracy in the interpretation of HRM and FLIP metrics and moderate-to-high levels for motility classification in FLIP, supporting the use of these approaches for primary or complementary evaluation of esophageal motility disorders.

OBJECTIVE: The gastrointestinal tract is commonly involved in patients with systemic sclerosis (SSc) with varied manifestations. As our understanding of SSc gastrointestinal disease pathogenesis and risk stratification is limited, we sought to investigate whether patterns of esophageal dysfunction associate with specific clinical phenotypes in SSc. METHODS: Patients enrolled in the Johns Hopkins Scleroderma Center Research Registry who completed high-resolution esophageal manometry (HREM) studies as part of their clinical care between 2011 and 2020 were identified. Associations between esophageal abnormalities on HREM (absent contractility [AC], ineffective esophageal motility [IEM], hypotensive lower esophageal sphincter [hypoLES]) and patient demographic information, clinical characteristics, and autoantibody profiles were examined. RESULTS: Ninety-five patients with SSc had HREM data. Sixty-five patients (68.4%) had AC (37 patients with only AC, 28 patients with AC and a hypoLES), 9 patients (9.5%) had IEM, and 11 patients (11.6%) had normal studies. AC was significantly associated with diffuse cutaneous disease (38.5% versus 10.0%; P

Purpose of reviewWhile guidelines exist for the evaluation and management of esophageal dysphagia in the general population, dysphagia disproportionately affects the elderly. In this article, we reviewed the literature on evaluating esophageal dysphagia in elderly patients and proposed a diagnostic algorithm based on this evidence.Recent findingsIn older patients, dysphagia is often well compensated for by altered eating habits and physiologic changes, underreported by patients, and missed by healthcare providers. Once identified, dysphagia should be differentiated into oropharyngeal and esophageal dysphagia to guide diagnostic workup. For esophageal dysphagia, this review proposes starting with endoscopy with biopsies, given its relative safety even in older patients and potential for interventional therapy. If endoscopy shows a structural or mechanical cause, then further cross-sectional imaging should be considered to assess for extrinsic compression, and same session endoscopic dilation should be considered for strictures. If biopsies and endoscopy are normal, then esophageal dysmotility is more likely, and high-resolution manometry and additional workup should be performed following the updated Chicago Classification. Even after diagnosis of the root cause, complications including malnutrition and aspiration pneumonia should also be assessed and monitored, as they both result from and can further contribute to dysphagia. The successful evaluation of esophageal dysphagia in elderly patients requires a thorough, standardized approach to collecting a history, selection of appropriate diagnostic workup, and assessment of risk of potential complications, including malnutrition and aspiration.

Gastrointestinal (GI) sequelae, such as vomiting, hyperacidity, dysphagia, dysmotility, and diarrhea, are nearly universal among patients with nephropathic cystinosis. These complications result from disease processes (e.g., kidney disease, cystine crystal accumulation in the GI tract) and side effects of treatments (e.g., cysteamine, immunosuppressive therapy). GI involvement can negatively impact patient well-being and jeopardize disease outcomes by compromising drug absorption and patient adherence to the strict treatment regimen required to manage cystinosis. Given improved life expectancy due to advances in kidney transplantation and the transformative impact of cystine-depleting therapy, nephrologists are increasingly focused on addressing extra-renal complications and quality of life in patients with cystinosis. However, there is a lack of clinical data and guidance to inform GI-related monitoring, interventions, and referrals by nephrologists. Various publications have examined the prevalence and pathophysiology of selected GI complications in cystinosis, but none have summarized the full picture or provided guidance based on the literature and expert experience. We aim to comprehensively review GI sequelae associated with cystinosis and its treatments and to discuss approaches for monitoring and managing these complications, including the involvement of gastroenterology and other disciplines.

The prevalence of esophageal motor disorders (EMD) in PPI-refractory gastroesophageal reflux disease (GERD) is substantial. However, limited data exist on their impact on the efficacy of endoscopic treatments like anti-reflux mucosectomy (ARMS). This study aimed to evaluate the influence of EMD on ARMS efficacy in patients with PPI-refractory GERD. This single-center retrospective study enrolled patients with refractory GERD treated with ARMS-b (anti-reflux mucosectomy band-ligation). High-resolution esophageal manometry (HREM) was conducted before the procedure to identify EMD presence. The primary endpoint was treatment efficacy, defined as >50% improvement in GERD-HRQL score at 1 year. Secondary endpoints included PPI intake, symptom control, ARMS complications, and overall patient satisfaction at 12 months. The study included 65 patients, with 41 (63.1%) showing EMD on HREM. Treatment efficacy was achieved by 33.8% (22) of patients, with 8 without EMD, 11 having isolated LES hypotonia, and 3 with both LES hypotonia and esophageal body motor disorder. No significant differences were observed between patients with and without EMD regarding the primary endpoint, PPI use, symptom control, or complications. Dysphagia developed in 52.3% (34) within 6 months, leading to esophageal dilatation in 15.3% (10). Two patients experienced acute hemorrhage, and one had perforation. The presence of esophageal motor disorders does not seem to impact ARMS response, suggesting the technique's consideration in this population. Larger studies are essential for confirming these results and exploring treatment response and post-operative predictors. [ABSTRACT FROM AUTHOR]

Background: Anti-reflux operations are effective treatments for GERD. Despite standardized surgical techniques, variability in post-operative outcomes persists. Most patients with GERD possess one or more characteristics that augment their disease and may affect post-operative outcomes—a GERD "phenotype". We sought to define these phenotypes and to compare their post-operative outcomes. Methods: We performed a retrospective review of a prospective gastroesophageal database at our institution, selecting all patients who underwent an anti-reflux procedure for GERD. Patients were grouped into different phenotypes based on the presence of four characteristics known to play a role in GERD: hiatal or paraesophageal hernia (PEH), hypotensive LES, esophageal dysmotility, delayed gastric emptying (DGE), and obesity. Patient-reported outcomes (GERD-HRQL, dysphagia, and reflux symptom index (RSI) scores) were compared across phenotypes using the Wilcoxon rank-sum test. Results: 690 patients underwent an anti-reflux procedure between 2008 and 2022. Most patients underwent a Nissen fundoplication (302, 54%), followed by a Toupet or Dor fundoplication (205, 37%). Twelve distinct phenotypes emerged. Non-obese patients with normal esophageal motility, normotensive LES, no DGE, with a PEH represented the most common phenotype (134, 24%). The phenotype with the best post-operative GERD-HRQL scores at one year was defined by obesity, hypotensive LES, and PEH, while the phenotype with the worst scores was defined by obesity, ineffective motility, and PEH (1.5 ± 2.4 vs 9.8 ± 11.4, p = 0.010). There was no statistically significant difference in GERD-HRQL, dysphagia, or RSI scores between phenotypes after five years. Conclusions: We have identified distinct phenotypes based on common GERD-associated patient characteristics. With further study these phenotypes may aid surgeons in prognosticating outcomes to individual patients considering an anti-reflux procedure. [ABSTRACT FROM AUTHOR]

Background and Aims: Gastrointestinal (GI) disorders are common in patients with eating disorders. However, the temporal relationship between GI and eating disorder symptoms has not been explored. We aimed to evaluate GI disorders among patients with eating disorders, their relative timing, and the relationship between GI diagnoses and eating disorder remission. Methods: We conducted a retrospective analysis of patients with an eating disorder diagnosis who had a GI encounter from 2010 to 2020. GI diagnoses and timing of eating disorder onset were abstracted from chart review. Coders applied DSM‐5 criteria for eating disorders at the time of GI consult to determine eating disorder remission status. Results: Of 344 patients with an eating disorder diagnosis and GI consult, the majority (255/344, 74.2%) were diagnosed with an eating disorder prior to GI consult (preexisting eating disorder). GI diagnoses categorized as functional/motility disorders were most common among the cohort (57.3%), particularly in those with preexisting eating disorders (62.5%). 113 (44.3%) patients with preexisting eating disorders were not in remission at GI consult, which was associated with being underweight (OR 0.13, 95% CI 0.04–0.46, p < 0.001) and increasing number of GI diagnoses (OR 0.47 per diagnosis, 95% CI 0.26–0.85, p = 0.01). Conclusions: Eating disorder symptoms precede GI consult for most patients, particularly in functional/motility disorders. As almost half of eating disorder patients are not in remission at GI consult. GI providers have an important role in screening for eating disorders. Further prospective research is needed to understand the complex relationship between eating disorders and GI symptoms. [ABSTRACT FROM AUTHOR]

Background: For many patients with lung disease the only proven intervention to improve survival and quality of life is lung transplantation (LTx). Esophageal dysmotility and gastroesophageal reflux (GER) are common in patients with respiratory disease, and often associate with worse prognosis following LTx. Which, if any patients, should be excluded from LTx based on esophageal concerns remains unclear. Our aim was to understand the effect of LTx on esophageal motility diagnosis and examine how this and the other physiological and mechanical factors relate to GER and clearance of boluses swallowed. Methods: We prospectively recruited 62 patients with restrictive (RLD) and obstructive (OLD) lung disease (aged 33–75 years; 42 men) who underwent high resolution impedance manometry and 24‐h pH‐impedance before and after LTx. Key Results: RLD patients with normal motility were more likely to remain normal (p = 0.02), or if having abnormal motility to change to normal (p = 0.07) post‐LTx than OLD patients. Esophageal length (EL) was greater in OLD than RLD patients' pre‐LTx (p < 0.001), reducing only in OLD patients' post‐LTx (p = 0.02). Reduced EL post‐LTx associated with greater contractile reserve (r = 0.735; p = 0.01) and increased likelihood of motility normalization (p = 0.10). Clearance of reflux improved (p = 0.01) and associated with increased mean nocturnal baseline impedance (p < 0.001) in RLD but not OLD. Peristaltic breaks and thoraco‐abdominal pressure gradient impact both esophageal clearance of reflux and boluses swallowed (p < 0.05). Conclusions and Inferences: RLD patients are more likely to show improvement in esophageal motility than OLD patients post‐LTx. However, the effect on GER is more difficult to predict and requires other GI, anatomical and pulmonary factors to be taken into consideration. [ABSTRACT FROM AUTHOR]

Background: Ingested foreign bodies pose a unique challenge in medical practice, especially when lodged in the oesophagus. While endoscopic retrieval is the standard treatment, certain cases require more innovative approaches. Methods: This paper reports the case of a patient who intentionally ingested a butter knife that lodged in the thoracic oesophagus. After multiple endoscopic attempts, a lateral neck oesophagotomy, aided using a Hopkins rod camera and an improvised trochar as a protective port, was performed. Results: The foreign body was successfully extracted without causing oesophageal perforation. The patient was made nil by mouth, with nasogastric feeding only until a swallow assessment after one week. The patient was discharged and recovered well. Conclusion: This case illustrates a successful, innovative approach to removing a foreign body in a high-risk patient, highlighting the significance of adaptability in surgical practice. It emphasises the need for individualised approaches based on the patient's history, the nature and location of the foreign body, and associated risks. [ABSTRACT FROM AUTHOR]

Background Non-achalasia esophageal motility disorders (NAEMDs), encompassing distal esophageal spasm (DES) and hypercontractile esophagus (HCE), are rare conditions. Peroral endoscopic myotomy (POEM) is a promising treatment option. In NAEMDs, unlike with achalasia, the lower esophageal sphincter (LES) functions normally, suggesting the potential of LES preservation during POEM. Methods This retrospective two-center observational study focused on patients undergoing LES-preserving POEM (LES-POEM) for NAEMD. Eckardt scores were assessed pre-POEM and at 6, 12, and 24 months post-POEM, with follow-up endoscopy at 6 months to evaluate for reflux esophagitis. Clinical success, defined as an Eckardt score ≤3, served as the primary outcome. Results 227 patients were recruited over 84 months until May 2021. Of these, 16 underwent LES-POEM for an NAEMD (9 with HCE and 7 with DES). The median pre-POEM Eckardt score was 6.0 (interquartile range [IQR] 5.0–7.0), which decreased to 1.0 (IQR 0.0–1.8; P <0.001) 6 months post-POEM. This was sustained at 24 months, with an Eckardt score of 1.0 (IQR 0.0–1.8; P<0.001). Two patients (12.5%) developed Los Angeles grade A or B esophagitis. Conclusions LES-POEM for NAEMD demonstrates favorable clinical outcomes, with infrequent esophagitis and reintervention for LES dysfunction rarely required. [ABSTRACT FROM AUTHOR]

Background: Achalasia is an esophageal motility disorder with an unknown etiology. We aimed to determine the pathogenesis of achalasia by studying alterations in esophageal smooth muscle contraction and the associated inflammatory response, and evaluate the role of esophageal microbiota in achalasia development. Methods: We analyzed esophageal mucosa and lower esophageal sphincter (LES) samples, obtained from patients with type II achalasia who underwent peroral endoscopic myotomy. Esophageal conditioned media obtained from patients were transferred into the mouse esophagus to determine whether the esophageal intraluminal environment is associated with achalasia. Results: Approximately 30% of 20-kDa myosin light chains (LC20) was phosphorylated in LES from the control group under resting and stimulated conditions, whereas less than 10% of LC20 phosphorylation was detected in achalasia under all conditions. The hypophosphorylation of LC20 in achalasia was associated with the downregulation of the myosin phosphatase-inhibitor protein CPI-17. Th17-related cytokines, including IL-17A, IL-17F, IL-22, and IL-23A, were significantly upregulated in achalasia. α-Diversity index of esophageal microbiota and the proportion of several microbes, including Actinomyces and Dialister, increased in achalasia. Actinomyces levels positively correlated with IL-23A levels, whereas Dialister levels were positively associated with IL-17A, IL-17F, and IL-22 levels. Esophageal IL-17F levels increased in mice after oral administration of the conditioned media. Conclusions: In LES of patients with achalasia, hypophosphorylation of LC20, a possible cause of impaired contractility, was associated with CPI-17 downregulation and an increased Th17-related immune response. The esophageal intraluminal environment, represented by the esophageal microbiota, could be associated with the development and exacerbation of achalasia. [ABSTRACT FROM AUTHOR]

Background and Aims: Up to 50% of patients with Parkinson disease have constipation (PD‐C), but the prevalence of defecatory disorders caused by rectoanal dyscoordination in PD‐C is unknown. We aimed to compare anorectal function of patients with PD‐C versus idiopathic chronic constipation (CC). Methods: Anorectal pressures, rectal sensation, and rectal balloon expulsion time (BET) were measured with high‐resolution anorectal manometry (HR‐ARM) in patients with PD‐C and control patients with CC, matched for age and sex. Results: We identified 97 patients with PD‐C and 173 control patients. Eighty‐six patients with PD‐C (89%) had early PD, and 39 (40%) had a defecatory disorder, manifest by a prolonged rectal balloon expulsion time (37 patients) or a lower rectoanal pressure difference during evacuation (2 patients). PD‐C patients with a prolonged BET had a greater anal resting pressure (p = 0.02), a lower rectal pressure increment (p = 0.005), greater anal pressure (p = 0.047), and a lower rectoanal pressure difference during evacuation (p < 0.001). Rectal sensory thresholds were greater in patients with abnormal BET. In the multivariate model comparing CC and PD‐C (AUROC = 0.76), PD‐C was associated with a lower anal squeeze increment (odds ratio [OR] for PD‐C, 0.93 [95% CI, 0.91–0.95]), longer squeeze duration (OR, 1.05 [95% CI, 1.03–1.08]), lower rectal pressure increment (OR per 10 mm Hg, 0.72 [95% CI, 0.66–0.79]), and negative rectoanal gradient during evacuation (OR per 10 mm Hg, 1.16 [95% CI, 1.08–1.26]). Conclusions: Compared with CC, PD‐C was characterized by impaired squeeze pressure, longer squeeze duration, lower increase in rectal pressure, and a more negative rectoanal gradient during evacuation.

INTRODUCTION: The natural history of rectal intussusception (RI) is poorly understood. We hypothesized that decline in pelvic floor integrity and function leads to increasing RI grades. METHODS: Retrospective analysis of a registry of patients with defecatory disorders with high-resolution anorectal manometry and magnetic resonance defecography was performed. Association of risk factors on increasing RI grades was assessed using logistic regression. RESULTS: Analysis included a total of 238 women: 90 had noRI, 43 Oxford 1--2, 49 Oxford 3, and 56Oxford 4--5. Age (P 5 0.017), vaginal delivery (P 5 0.008), and prior pelvic surgery (P 5 0.032) were associated with increased Oxford grades. Obstructive defecation symptoms and dyssynergic defecation were observed at relatively high rates across groups. Increased RI grades were associated with less anal relaxation at simulated defecation yet, higher rates of normal balloon expulsion (P < 0.05), linked to diminished anal sphincter. Indeed, increased RI grades were associated with worsening fecal incontinence severity, attributed to higher rates of anal hypotension. Levator ani laxity, defined by increased levator hiatus length and its excessive descent at straining,was associated with increasing RI grades, independent of age, history of vaginal delivery, and pelvic surgeries and could independently predict increased RI grades. Concurrent anterior and posterior compartments, and visceral prolapse were associated with higher Oxford grades. DISCUSSION: Our data suggest that decline in pelvic floor integrity with abnormal levator ani laxity is associated with increased RI grades, a process that is independent of age, history of vaginal deliveries, and/or pelvic surgeries, and perhaps related to dyssynergic defecation.

Achalasia is a rare esophageal disorder characterized by abnormal esophageal motility and swallowing difficulties. Pain and/or spasms often persist or recur despite effective relief of the obstruction. A survey by UK charity 'Achalasia Action' highlighted treatments for achalasia pain/spasms as a key research priority. In this patient-requested systematic review, we assessed the existing literature on pharmacological therapies for painful achalasia. A systematic review of the literature using Medline, Embase and Cochrane databases was performed to identify studies evaluating pharmacological therapies for achalasia. Methodological quality of included randomized controlled trials was assessed using the Cochrane Risk of Bias tool. In total, 70% (40/57) of survey respondents reported experiencing pain/spasms. A range of management strategies were reported. Thirteen studies were included in the review. Seven were randomized controlled trials. Most studies were >30 years old, had limited follow-up, and focussed on esophageal manometry as the key endpoint. Generally, studies found improvements in lower esophageal pressures with medications. Only one study evaluated pain/spasm specifically, precluding meta-analysis. Overall risk of bias was high. The achalasia patient survey identified that pain/spasms are common and difficult to treat. This patient-requested review identified a gap in the literature regarding pharmacological treatments for these symptoms. We provide an algorithm for investigating achalasia-related pain/spasms. Calcium channel blockers or nitrates may be helpful when esophageal obstruction and reflux have been excluded. We advocate for registry-based clinical trials to expand the evidence base for these patients. [ABSTRACT FROM AUTHOR]

Esophageal diverticulum is a rare condition characterized by the herniation of the esophageal mucosa outside the esophageal wall. Here, we explore the prevalence of ED and its associated esophageal dysmotility. We also shed light on the potential impact of previous surgical interventions, such as Nissen's fundoplication, on the development of ED. This manuscript presents the case of a 72-year-old woman with a history of Nissen's fundoplication surgery who experienced worsening symptoms of dysphagia, heartburn and postprandial cough. Despite exhibiting a normal motility pattern, upper endoscopy revealed a large epiphrenic esophageal diverticulum. The patient underwent successful surgical resection with myotomy, resulting in the resolution of symptoms with no complications. This case highlights the rarity of symptomatic ED and the need to recognize it while choosing the optimal treatment modality. [ABSTRACT FROM AUTHOR]

Background: Achalasia is an esophageal motor disorder characterized by aperistalsis and the failure of the relaxation of the lower esophageal sphincter. We want to find out whether external compression or recurrent micro-aspiration of undigested food has a functional effect on the airway. Methods: The aim of this research was to analyze the influence of achalasia on the peak expiratory flow and flow–volume curve. All of the 110 patients performed spirometry. Results: The mean diameter of the esophagus was 5.4 ± 2.1 cm, and nine of the patients had mega-esophagus. Seven patients had a plateau in the inspiratory part of the flow–volume curve, which coincides with the patients who had mega-esophagus. The rest of the patients had a plateau in the expiration part of the curve. The existence of a plateau in the diameter of the esophagus of more than 5 cm was significant (p 0.003). Statistical significance between the existence of a plateau and a lowered PEF (PEF < 80) has been proven (p 0.001). Also, a statistical significance between the subtype and diameter of more than 4 cm has been proved. There was no significant improvement in the PEF values after operation. In total, 20.9% of patients had a spirometry abnormality finding. The frequency of the improvement in the spirometry values after surgery did not differ significantly by achalasia subtype. The improvement in FEV1 was statistically significant compared to the FVC values. Conclusions: Awareness of the influence of achalasia on the pulmonary parameters is important because low values of PEF with a plateau on the spirometry loop can lead to misdiagnosis. The recognition of various patterns of the spirometry loop may help in identifying airway obstruction caused by another non-pulmonary disease such as achalasia. [ABSTRACT FROM AUTHOR]

OBJECTIVES: Ventilator dyssynchrony may be associated with increased delivered tidal volumes (V t s) and dynamic transpulmonary pressure (ΔPL,dyn), surrogate markers of lung stress and strain, despite low V t ventilation. However, it is unknown which types of ventilator dyssynchrony are most likely to increase these metrics or if specific ventilation or sedation strategies can mitigate this potential. DESIGN: A prospective cohort analysis to delineate the association between ten types of breaths and delivered V t , ΔPL,dyn, and transpulmonary mechanical energy. SETTING: Patients admitted to the medical ICU. PATIENTS: Over 580,000 breaths from 35 patients with acute respiratory distress syndrome (ARDS) or ARDS risk factors. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Patients received continuous esophageal manometry. Ventilator dyssynchrony was identified using a machine learning algorithm. Mixed-effect models predicted V t , ΔPL,dyn, and transpulmonary mechanical energy for each type of ventilator dyssynchrony while controlling for repeated measures. Finally, we described how V t , positive end-expiratory pressure (PEEP), and sedation (Richmond Agitation-Sedation Scale) strategies modify ventilator dyssynchrony's association with these surrogate markers of lung stress and strain. Double-triggered breaths were associated with the most significant increase in V t , ΔPL,dyn, and transpulmonary mechanical energy. However, flow-limited, early reverse-triggered, and early ventilator-terminated breaths were also associated with significant increases in V t , ΔPL,dyn, and energy. The potential of a ventilator dyssynchrony type to increase V t , ΔPL,dyn, or energy clustered similarly. Increasing set V t may be associated with a disproportionate increase in high-volume and high-energy ventilation from double-triggered breaths, but PEEP and sedation do not clinically modify the interaction between ventilator dyssynchrony and surrogate markers of lung stress and strain. CONCLUSIONS: Double-triggered, flow-limited, early reverse-triggered, and early ventilator-terminated breaths are associated with increases in V t , ΔPL,dyn, and energy. As flow-limited breaths are more than twice as common as double-triggered breaths, further work is needed to determine the interaction of ventilator dyssynchrony frequency to cause clinically meaningful changes in patient outcomes.

This article highlights the characteristics and clinical symptoms of esophageal involvement in patients with SSc. Patients and Methods: This study was conducted between November 2022 to August 2023, including 26 already diagnosed cases of SSc in the Department of Rheumatology and Rehabilitation and Kurdistan Center for Gastroenterology and Hepatology-Sulaymaniyah, Iraq. Esophageal involvement was investigated using esophageal manometry, esophagogastroduodenoscopy (EGD), and 24-hour impedance-pH monitoring. Results: Females were significantly predominant (P = 0.019) regarding the symptoms; 76.9% of the patients had heart burn, 76.9% dysphagia, 73.1% water brush, and 69.2% regurgitation. In total, 69.2% of the patients showed erosive gastrointestinal reflux disease (GERD) on EGD, 76.9% had decreased lower esophageal sphincter pressure (DLESP) and decreased distal esophageal peristaltic contractions (DDEPC) on esophageal manometry, and 84.6% had reflux on pH monitoring. Raynaud's phenomenon is the most common and typically the earliest clinical manifestation of SSc. The presence of erosive GERD was found to significantly increase the risk of developing dysphagia (B = 4.725, P = 0.014, OR = 3.482) and regurgitation (B = 3.521, P = 0.006, OR = 4.030). Conclusion: It is crucial to take gender-specific considerations into account when diagnosing and managing esophageal complications in patients with systemic sclerosis (SSc). Additionally, employing various diagnostic assessments to detect esophageal involvement during SSc is essential. Erosive GERD has been identified as a risk factor that contributes to the development of dysphagia and regurgitation in individuals with SSc. [ABSTRACT FROM AUTHOR]- Published

Major esophageal disorders involve obstructive transport of bolus to the stomach, causing symptoms of dysphagia and impaired clearing of the refluxed gastric contents. These may occur due to mechanical constriction of the esophageal lumen or loss of relaxation associated with deglutitive inhibition, as in achalasia-like disorders. Recently, immune inflammation has been identified as an important cause of esophageal strictures and the loss of inhibitory neurotransmission. These disorders are also associated with smooth muscle hypertrophy and hypercontractility, whose cause is unknown. This review investigated immune inflammation in the causation of smooth muscle changes in obstructive esophageal bolus transport. Findings suggest that smooth muscle hypertrophy occurs above the obstruction and is due to mechanical stress on the smooth muscles. The mechanostressed smooth muscles release cytokines and other molecules that may recruit and microlocalize mast cells to smooth muscle bundles, so that their products may have a close bidirectional effect on each other. Acting in a paracrine fashion, the inflammatory cytokines induce genetic and epigenetic changes in the smooth muscles, leading to smooth muscle hypercontractility, hypertrophy, and impaired relaxation. These changes may worsen difficulty in the esophageal transport. Immune processes differ in the first phase of obstructive bolus transport, and the second phase of muscle hypertrophy and hypercontractility. Moreover, changes in the type of mechanical stress may change immune response and effect on smooth muscles. Understanding immune signaling in causes of obstructive bolus transport, type of mechanical stress, and associated smooth muscle changes may help pathophysiology-based prevention and targeted treatment of esophageal motility disorders.

Background/Aims: There is an increased incidence of gastroesophageal reflux disease (GERD) after lung transplantation (LT) that can be associated with graft dysfunction. It is unclear if the underlying esophageal motility changes in GERD are different following LT. This study aimed to use esophageal high-resolution manometry (HRM) to explore GERD mechanisms in LT recipients compared to matched controls. Methods: This was a retrospective study including patients with pathologic acid reflux who underwent HRM and pH testing at our healthcare facility July 2012 to October 2019. The study included 12 LT recipients and 36 controls. Controls were matched in a 1:3 ratio for age, gender, and acid exposure time (AET) Results: LT recipients had less hypotensive esophagogastric junction (EGJ) (mean EGJ-contractile integral 89.2 mmHg/cm in LT vs 33.9 mmHg/cm in controls, P < 0.001). AET correlated with distal contractile integral and total EGJ-contractile integral only in LT group (r = -0.79, P = 0.002 and r = -0.57, P = 0.051, respectively). Conclusions: Following LT, acid reflux is characterized by a less hypotensive EGJ compared to controls with similar AET. The strongest correlation with AET after LT was found to be esophageal peristaltic vigor. These results add to the understanding of reflux after LT and may help tailor an individualized treatment plan. [ABSTRACT FROM AUTHOR]

Background: Previous studies have demonstrated that 50% of patients with normal high‐resolution manometry (HRM) findings or ineffective esophageal motility (IEM) may have abnormal functional luminal imaging probe (FLIP) results. However, the specific HRM findings associated with abnormal FLIP results are unknown. Herein, we investigated the relationship between nonspecific manometry findings and abnormal FLIP results. Methods: We retrospectively analyzed 684 patients who underwent HRM at a tertiary care center in Seoul, Korea, based on the Chicago Classification version 4.0 protocol. Key Results: Among the 684 patients, 398 had normal HRM findings or IEM. Of these 398 patients, eight showed esophageal wall thickening on endoscopic ultrasonography or computed tomography; however, no abnormalities were seen during esophagogastroduodenoscopy. Among these eight patients, seven showed repetitive simultaneous contractions (RSCs) in at least one of the two positions: 61% (±29%) in 10 swallows in the supine position and 51% (±30%) in five swallows in the upright position. Four patients who underwent FLIP had a significantly decreased esophagogastric junction distensibility index (1.0 ± 0.5 mm2mmHg−1 at 60 mL). Two of these patients underwent per‐oral endoscopic myotomy (POEM) due to a lack of response to medication. Esophageal muscle biopsy revealed hypertrophic muscle with marginal eosinophil infiltration. Conclusions & Inferences: A subset of patients (2%) with normal HRM findings or IEM and RSCs experienced dysphagia associated with poor distensibility of the thickened esophageal wall. FLIP assessment or combined HRM and impedance protocols may help better define these patients who may respond well to POEM. [ABSTRACT FROM AUTHOR]

There is little information on the degree of concordance between the results obtained using the Chicago 3.0 (CCv3.0) and Chicago 4.0 (CCv4.0) protocols to interpret high-resolution manometry (HRM) seeking to determine the value provided by the new swallowing maneuvers included in the last protocol. This is a study of diagnostic tests, evaluating concordance by consistency between the results obtained by the CCv3.0 and CCv4.0 protocols, in patients undergoing HRM. Concordance was assessed with the kappa test. Bland–Altman scatter plots, and Lin's correlation-concordance coefficient (CCC) were used to assess the agreement between IRP measured with swallows in the supine and seated position or with solid swallows. One hundred thirty-two patients were included (65% women, age 53 ± 17 years). The most frequent HRM indication was dysphagia (46.1%). Type I was the most common type of gastroesophageal junction. The most frequent CCv4.0 diagnoses were normal esophageal motility (68.9%), achalasia (15.5%), and ineffective esophageal motility (IEM; 5.3%). The agreement between the results was substantial (Kappa 0.77 ± 0.05), with a total agreement of 87.9%. Diagnostic reclassification occurred in 12.1%, from IEM in CCv3.0 to normal esophageal motility in CCv4.0. Similarly, there was a high level of agreement between the IRP measured in the supine compared to the seated position (CCC0.92) and with solid swallows (CCC0.96). In conclusion, the CCv4.0 protocol presents a high concordance compared to CCv3.0. In the majority of manometric diagnoses there is no reclassification of patients with provocation tests. However, the more restrictive criteria of CCv4.0 achieve a better reclassification of patients with IEM. [ABSTRACT FROM AUTHOR]
