- Abstract
Background and Aims: GERD is common after peroral endoscopic myotomy (POEM). Selective sparing of oblique fibers may reduce the incidence of reflux esophagitis after POEM. In this study, we compared the incidence of GERD between conventional myotomy (CM) versus oblique fiber-sparing (OFS) myotomy in patients with achalasia., Methods: Eligible patients with type I and II achalasia who underwent POEM from January 2020 to October 2020 were randomized into 2 groups (CM and OFS myotomy). Exclusion criteria were type III achalasia, sigmoid esophagus, and history of Heller's myotomy. The primary study outcome was incidence of reflux esophagitis (at least grade B) in the 2 groups. Secondary outcomes were reflux symptoms, esophageal acid exposure, clinical success, and adverse events., Results: One hundred fifteen patients were randomized into CM (n = 58) and OFS myotomy (n = 57) groups. POEM was technically successful in all patients. Overall, reflux esophagitis was found in 56 patients (48.7%). The incidence of at least grade B esophagitis was similar in both groups (CM vs OFS myotomy: 25.9% vs 31.6%, P = .541). The mean number of reflux episodes (48.2 ± 36.6 vs 48.9 ± 40.3, P = .933), increased esophageal acid exposure >6% (45.5% vs 31.7%, P = .266), and high DeMeester scores (38.6% vs 41.5%, P = .827) were similar in both groups. There was no difference in the rate of symptomatic reflux (GERD questionnaire score >7) or use of proton pump inhibitors at 1 year., Conclusions: Sparing of sling fibers has no significant impact on the incidence of significant reflux esophagitis after POEM. Novel strategies need to be explored to prevent reflux after POEM.

- Abstract
Per-oral endoscopic myotomy (POEM) is an established treatment modality in adult patients with achalasia cardia. There are limited data regarding the efficacy and safety of POEM in pediatric achalasia. In this systematic review and meta-analysis, we aimed to analyze the outcomes of POEM in children and adolescents with achalasia cardia. Literature search was performed in Embase, PubMed, and Cochrane database for studies evaluating the outcome of POEM in pediatric achalasia between January 2010 and March 2021. Primary objective of the study was clinical success (Eckardt ≤ 3). Secondary outcomes included technical success, procedure duration, adverse events , and gastroesophageal reflux after POEM. A total of 14 studies (419 children, 234 boys) were included in the review. The subtypes of achalasia were type I (30.6%), type II (63.8%), and type III (5.6%). Pooled rate of technical success was 97.1% (95% CI 94.5-98.5%; I
2 = 0). Pooled clinical success in intention to treat and per-protocol population was 88% (95% CI 84.4-90.9%; I2 = 0) and 94.4% (95% CI 91.5-96.4%; I2 = 0), respectively. Post-POEM, pooled mean reduction in Eckardt scores was 6.71 (95% CI 6.14 7.28; p < 0.001; I2 = 81%). Pooled rate for overall adverse events was 12.9% (95% CI 7.4-21.7%; I2 64.5%), major adverse events was 4.2% (95% CI 2.4-7.4%), and erosive esophagitis was 26.3% (95% CI 17.5-37.7%; I2 51%). POEM is an effective procedure in children with achalasia. Future studies are required to determine the durability of response and comparative outcomes with other treatment modalities for achalasia., (© 2022.

- Abstract
Esophageal epiphrenic diverticula (EED) are rare pulsion-type outpouchings at the lower end of esophagus. Traditionally, surgery has been performed in EED. More recently, per-oral endoscopic myotomy with septotomy (D-POEM) has emerged as an option in these cases. In this study, we aim to determine the efficacy and safety of D-POEM in cases with EED. The data of cases who underwent D-POEM in cases with EED from March 2013 to Nov 2020 were analyzed, retrospectively. The primary outcome of the study was clinical success. Secondary outcomes included technical success, procedure duration, reflux esophagitis, and adverse events. 13 patients (males 9, 48.07 ± 17.55 years) with EED underwent D-POEM during the study period. Median size of the EED was 45 mm (range 25-70). Associated esophageal motility disorder was found in 10 (76.9%) cases including type II achalasia (3), type I (3), hypercontractile esophagus (2), and unspecified (2). Technical success was achieved in 12 (92.3%) cases. Median length of total and gastric myotomies were 10 cm (range 6-20) and 3 cm (1-3), respectively. At a median follow-up of 25 months, clinical success was achieved in 84.6% cases. Mean integrated relaxation pressures reduced significantly after POEM procedure (25.80 ± 13.24 vs 9.40 ± 3.10, p = 0.001). There was one major adverse event requiring surgical intervention. D-POEM is an effective procedure in cases with EED. Long-term follow-up studies are required to ascertain the durability of response in these cases., (© 2021.

- Abstract
Background: There is limited data on long-term outcomes of per-oral endoscopic myotomy (POEM). In this study, we aim to evaluate the efficacy of POEM in patients who completed a minimum follow-up of 5 years., Methods: Data of patients who underwent POEM and completed ≥ 5-year follow-up were analyzed, retrospectively. Primary outcome of study was clinical success (Eckardt ≤ 3) at ≥ 5 years after POEM. Secondary outcomes included predictors of dysphagia and symptomatic gastroesophageal reflux disease (GERD) on long-term follow-up., Results: Three hundred nineteen patients (males 182, mean age 40.5 ± 14.2 years) completed a median of 73-(60-89) month follow-up. Esophageal motility disorders included idiopathic achalasia (type I 26.6%, type II 60.8%, type III 5.6%) and Jackhammer esophagus or distal esophageal spasm (2.8%). POEM was technically successful in 307 (96.2%) patients. Long-term success was 92.6% (overall), 92.1% (type I), 94.7% (type II), 87.5% (type III), and 75% (Jackhammer esophagus/distal esophageal spasm). Symptomatic GERD and reflux esophagitis were detected in 28.9% and 35.3% patients, respectively. On multivariate analysis, young age and female gender were independent risk factors for recurrent dysphagia (p = 0.037) and symptomatic GERD after POEM (p = 0.025), respectively. Lower post-POEM lower esophageal sphincter pressure was an independent predictor for reflux esophagitis (p = 0.016)., Conclusion: POEM is an effective and durable treatment for achalasia and non-achalasia spastic motility disorders. Young patients and females may be at higher risk for recurrent dysphagia and symptomatic GERD, respectively., (© 2022. The Society for Surgery of the Alimentary Tract.)

- Abstract
Background: : Peroral endoscopic myotomy (POEM) is an established modality of treatment for achalasia cardia. Considerable variations exist in the technique of POEM with respect to the length and orientation of the myotomy. In this systematic review and meta-analysis, we compared the outcomes of short versus long myotomy during POEM., Methods: : We searched multiple databases from January 2010 to March 2021 to identify studies reporting on POEM. We selected studies that reported on comparative outcomes of POEM using short versus long myotomy. We performed a comparative analysis of clinical success, procedural duration, gastroesophageal reflux disease (GERD), and adverse events with short and long myotomy in POEM by meta-analysis., Results: : A total of 521 patients from five studies in which 241 patients were treated with short and 280 patients with long myotomy approaches were analyzed. The pooled rate for clinical success gave an odds ratio (OR) of 1.27 (95% confidence interval [CI] 0.50-3.26; I
2 = 0; P = 0.62); for hospital stay OR 0.22 (95% CI - 0.03 to 0.46; I2 = 0; P = 0.08); for GERD by esophagogastroduodenoscopy (EGD) OR 0.58 (95% CI 0.31-1.07; I2 = 0; P = 0.08), and for adverse events OR 0.67 (95% CI 0.29-1.53; I2 = 51; P = 0.34). Abnormal esophageal acid exposure was less frequent with OR 0.45 (95% CI 0.22-0.90; P = 0.02; I2 = 0) and the procedure duration was significantly shorter in the short myotomy group with OR - 0.76 (95% CI - 1.00 to - 0.52; I2 = 43; P =0.001)., Conclusion: : Short myotomy and long myotomy in POEM seem comparable with each other in terms of clinical success and adverse events. Short myotomy is associated with significantly shorter procedural duration and possibly reduced esophageal acid exposure compared with long myotomy., Competing Interests: None- Published

- Abstract
Patients with achalasia frequently develop gastroesophageal reflux (GER)-related symptoms and complications after per-oral endoscopic myotomy (POEM). Reflux symptoms are thought to be due to GER and the current treatment of post-POEM GER focuses on acid suppression with proton pump inhibitors (PPI). However, reflux symptoms in achalasia patients post-POEM can be due to true reflux, nonreflux esophageal acidification due to stasis or acid fermentation, or esophageal hypersensitivity to chemical or mechanical stimuli. True acidic reflux is not always the cause of reflux symptoms. Twenty-four-hour pH monitoring with impedance is essential to differentiate causes of esophageal acidification. PPI is useful only in true acidic reflux. Detection of acid fermentation requires manual review of a 24-h pH study, as automated review often overestimates acid exposure time due to its inability to differentiate true reflux from fermentation. Stasis of ingested acidic food warrants evaluation of esophageal emptying by timed barium esophagogram. In cases of inadequate emptying, esophagogastric junction (EGJ) distensibility can be evaluated by a functional lumen imaging probe. Impaired distensibility with inadequate esophageal emptying suggests treatment failure and may require retreatment. In treatment-refractory patients, esophageal hypersensitivity should be considered and treated with neuromodulators. Thus, the diagnostic approach to post-POEM reflux symptoms should evolve to identify various patterns of esophageal acidification, esophageal emptying patterns, EGJ distensibility, and hypersensitivity. Consequently, the treatment of GER post-POEM should not be limited to treating esophageal acidification by reflux, but should encompass other causes of acidification and esophageal hypersensitivity., (© 2021 Japan Gastroenterological Endoscopy Society.)

- Abstract
Background and Aim: Peroral endoscopic myotomy (POEM) is emerging as an effective treatment for achalasia in children. Long-term outcomes of POEM and impact of prior treatment are not known in pediatric population. In this study, we aim to evaluate the long-term efficacy of POEM in children with achalasia., Methods: Children (≤18 years) with achalasia who underwent POEM and completed at least 36 months of follow-up were included in the study. Long-term clinical success (Eckardt ≤3) was evaluated and compared between treatment naïve versus prior treated cases., Results: A total of 53 children underwent POEM at our center during the study period. Of these, 17 children completed at least 3 years of follow-up and were included in the study. Eight children had prior treatment including pneumatic dilatation (6), Heller's myotomy (1) and both Heller's myotomy and pneumatic dilatation (1). POEM was successfully completed in all the children. Median procedure duration was 95.76 ± 47.98 min (38-240 min.). Long-term clinical success was found in 88.2% children. The mean follow-up was 55.06 ± 10.65 months (range 36-67 months). There was no significant difference in the success rate between treatment naïve and prior treatment failure cases., Conclusion: POEM is a safe, effective and durable treatment for achalasia in children. Prior treatment does not affect the outcomes of POEM in children., Type of Study: Retrospective comparative study., Level of Evidence: III., (Copyright © 2019 Elsevier Inc. All rights reserved.)

- Abstract
Background: Gastroesophageal reflux disease (GERD) is an important concern after peroral endoscopic myotomy (POEM). However, there are limited data on the risk factors for post-POEM GERD and its responsiveness to proton pump inhibitors (PPIs). In this study, we aimed to analyze the variables affecting the occurrence of GERD and its response to PPI therapy., Methods: Consecutive patients with idiopathic achalasia who underwent POEM (December 2016 to January 2018) were evaluated for GERD using 24-hour pH impedance, esophagogastroduodenoscopy (EGD), and symptoms. Multivariate analysis was performed to identify the variables affecting the incidence of post-POEM GERD., Results: A total of 209 patients with esophageal motility disorders, including 194 patients with non-sigmoid achalasia, underwent POEM during the study period. Comprehensive evaluation of GERD was completed on 167 patients (86.1 %): 47.3 % women with a mean (standard deviation) age of 41 (14.42) years and body mass index of 22.2 (3.89) kg/m
2 ; the majority (70.7 %) were treatment naïve. A high DeMeester score (> 14.72), reflux esophagitis, and symptomatic GERD were identified in 47.9 %, 41.9 %, and 29.3 % of patients, respectively. On logistic regression analysis, type of achalasia, technique of POEM (anterior vs. posterior), pre- or post-POEM esophageal manometry variables, and patient characteristics were not associated with post-POEM GERD. Erosive esophagitis responded to PPI therapy in the majority of patients (81.4 %)., Conclusion: The incidence of GERD is high after POEM. Most of the reflux esophagitis is mild and responsive to PPI therapy. There are no procedural or patient-related variables that appear to affect the incidence of post-POEM GERD., Competing Interests: The authors declare that they have no conflict of interest., (© Georg Thieme Verlag KG Stuttgart · New York.)- Published

- Abstract
Per-oral endoscopic myotomy (POEM) has surfaced as an effective endoscopic treatment modality for achalasia cardia (AC). Promising results in short- and mid-term follow-up studies have increased the use of POEM for the management of AC. POEM can be safely performed in an endoscopy suit, and major adverse events (AEs) are uncommon. AEs encountered during POEM or during the perioperative period principally include insufflation-related AEs, mucosal injuries, bleeding, pain, and aspiration pneumonia. Most insufflation-related AEs do not require an active intervention and therefore should not be considered as AEs in the true sense. When management of AEs is required, most intraoperative AEs can be managed at the same time without untoward consequences. Occurrences of AEs lessen after completion of the learning curve. However, experience alone does not ensure "zero" incidence of AEs, and early recognition remains essential. Postoperative AEs, like leaks, delayed bleeding, and delayed mucosal perforations, may pose special challenges for diagnosis and management. There is no standardized classification system for grading the severity of AEs associated with POEM, resulting in wide variation in their reported occurrences. Uniform reporting of AEs is not only crucial to comprehensively analyze the safety of POEM but also for comparison with other established treatment modalities like Heller's myotomy. GERD is an important long-term AE after POEM. Unlike the perioperative AEs, little is known regarding the intraoperative or patient-related factors that influence the occurrence of post-POEM GERD. Large prospective studies with long-term follow-up are required to determine the procedural factors associated with GERD after POEM., (Copyright © 2018. Published by Elsevier Inc.)

- Abstract
Background and Aim: Peroral endoscopic myotomy (POEM) is a technically demanding procedure. Recently, a new triangular knife with integrated water jet function (TTJ) has been introduced. The present study was aimed to analyze and compare the operating time, efficacy, and adverse events (AEs) between the conventional (TT knife) and new knife (TTJ)., Patients and Methods: All patients with achalasia cardia (AC) who underwent POEM between August 2015 and November 2016 were analyzed retrospectively. Operating time (OT), technical success, and AEs were assessed and compared between TT and TTJ knife., Results: A total of 193 patients with AC underwent POEM during the specified period. Both groups had equivalent number of different subtypes of AC (I, II, and III). There was no difference in technical success between the two groups (TT, 99% vs TT, 98.9%). OT was significantly less in the TTJ group as compared to TT group (53.8 ± 15.2 vs 66.26 ± 19.2; P = 0.0001). On subanalysis, OT taken for submucosal tunneling was significantly less with TTJ knife (34.6 ± 10.1 vs 45.83 ± 14.80), whereas OT was similar for myotomy and clipping in both the groups. Significantly fewer use of coagulation forceps and exchanges of accessories were required in TTJ knife group (2.92 ± 1.77 vs 10.5 ± 3.58; P = 0.0001). There were no major AEs. Minor AEs were noted in 21.5% and 31% of patients in TTJ and TT knife groups, respectively., Conclusion: New triangular knife reduces procedure time and technical difficulty with POEM. POEM is an efficacious treatment for achalasia and can be safely executed in an endoscopy unit., Competing Interests: There are no conflicts of interest.

Background/Aims: Per-oral endoscopic myotomy (POEM) is an established treatment for achalasia. The technique of POEM is still evolving and the impact of length of esophageal myotomy on the outcomes of POEM is not known. In this study, we aim to compare the outcomes of short (3 cm) versus long (6 cm and above) esophageal myotomy in patients undergoing POEM for achalasia cardia. Methods: Consecutive patients with idiopathic achalasia (type I and II) were randomized to receive short (3 cm) or long esophageal myotomy (≥ 6 cm). Both groups were compared for clinical success, operative time, adverse events, and gastroesophageal reflux disease (GERD). Results: Seventy-one consecutive patients with type I and II achalasia underwent POEM with short (n = 34) or long (n = 37) esophageal myotomy techniques. Mean length of esophageal myotomy in short and long groups was 2.76 ± 0.41 and 7.97 ± 2.40, respectively (P < 0.001). Mean operative time was significantly shorter in short myotomy group (44.03 ± 13.78 minutes and 72.43 ± 27.28 minutes, P < 0.001). Clinical success was comparable in both arms at 1-year (Eckardt score 0.935 ± 0.929 vs 0.818 ± 0.983, P = 0.627). Improvement in objective parameters including integrated relaxation pressure and barium column height at 5 minutes was similar in both groups. GERD was detected in 50.88% patients with no significant difference in short and long myotomy groups (44.44% vs 56.67%, P = 0.431). Conclusions: A short esophageal myotomy is non-inferior to long myotomy with regards to clinical success, adverse events, and GERD in cases with type I and II achalasia. Reduced operating duration favors short esophageal myotomy in these patients. [ABSTRACT FROM AUTHOR]

Background Zenker's diverticulum (ZD) is a rare disease that affects elderly subjects. The mainstay of management is endoscopic myotomy of the cricopharyngeal septum. In this series, we aimed to evaluate the feasibility and efficacy of cricopharyngeal myotomy with a new electrosurgical knife in patients with ZD. Methods Consecutive patients with ZD who underwent flexible endoscopic myotomy with the new triangle tip knife J (TTJ) were included in the study. The study outcomes included technical and clinical success, procedure duration, and adverse events. Results A total of 7 patients [median age 57 (range 40-87) years] underwent cricopharyngeal myotomy with the TTJ knife. The median size of the ZD was 4 (range 3-5) cm. The procedure was successfully completed in all the patients with a median operative time of 12 (range 8-16) min. There were no major adverse events. Minor bleeding was noticed in 3 patients and was successfully managed using the same knife. Clinical resolution of symptoms was noticed in all the patients at follow up. Conclusion Cricopharyngeal myotomy can be performed safely and efficiently with the new TTJ knife. [ABSTRACT FROM AUTHOR]
