Background Aims and Methods Results Conclusions Dumping syndrome is a complex of gastrointestinal symptoms originally studied in peptic ulcer surgery patients. At present, it is most prevalent in patients who underwent bariatric, upper gastrointestinal cancer or anti‐reflux surgery. The symptom pattern comprises early and late dumping symptoms. Several management options have been reported including nutritional, pharmacological and surgical approaches.In this study, we aimed to review the current evidence on dumping syndrome definition, diagnosis and treatment, including preliminary data from newer pharmacological studies.Current pathophysiological concepts and analyses of provocative tests has led to a clear definition of dumping syndrome, including both early and late dumping symptoms. The term postbariatric hypoglycemia represents a limited focus on late dumping only. The diagnosis relies on recognition of symptoms and signs in a patient with appropriate surgical history; and can be confirmed by provocative testing or registration of spontaneous hypoglycemia. The initial treatment focuses on dietary intervention, to which meal viscosity enhancers and/or the glycosidase inhibitor acarbose can be added. The most effective therapy is the use of short‐ or long‐acting somatostatin analogues, which is however expensive and entails side effect issues. In case of refractory hypoglycemia, diazoxide or SGLT2 inhibitors can be considered, based on limited evidence. In refractory patients, continuous enteral feeding or (rarely) surgical reinterventions have been advocated, although not supported by solid evidence. Therapies under current evaluation include the broad‐spectrum somatostatin analogue pasireotide, GLP‐1 receptor antagonists, GLP‐1 receptor agonists and administration of stable forms of glucagon are currently under study.Dumping syndrome is a well‐defined but probably under‐diagnosed complication of upper gastrointestinal, especially bariatric, and surgeries. Diagnosis is confirmed by a provocative test and incremental therapies starting with diet, adding meal viscosity enhancers or glycosidase inhibitors and adding somatostatin analogues in refractory cases. A number of emerging therapies targeting intestinal propulsion, peptide hormone effects and hypoglycemic events are under evaluation. [ABSTRACT FROM AUTHOR]

BACKGROUND: The historic morbidity and mortality rates of antireflux and hiatal hernia operation are reported as 3% to 21% and 0.2% to 0.5%, respectively. These data come from either large national and population level or small institutional studies, with the former focusing on broad 30-day outcomes while lacking granular data on complications and their severity. Institutional studies tend to focus on long-term and quality-of-life outcomes. Our objective is to describe and evaluate the incidence of 30- and 90-day morbidity and mortality in a large, single-institution dataset. STUDY DESIGN: We retrospectively reviewed 2,342 cases of antireflux and hiatal hernia operation from 2003 to 2020 for intraoperative complications causing postoperative sequelae, as well as morbidity and mortality within 90 days. All complications were graded using the Clavien-Dindo (CD) grading system. The highest grade of complication was used per patient during 30- and 31- to 90-day intervals. RESULTS: Of 2,342 patients, the overall 30-day morbidity and mortality rates were 18.2% (427 of 2,342) and 0.2% (4 of 2,342), respectively. Most of the complications were CD less than 3a at 13.1% (306 of 2,342). In the 31- to 90-day postoperative period, morbidity and mortality rates decreased to 3.1% (78 of 2,338) and 0.09% (2 of 2,338). CD less than 3a complications accounted for 1.9% (42 of 2,338). CONCLUSIONS: Antireflux and hiatal hernia operations are safe with rare mortality and modest rates of morbidity. However, the majority of complications patients experience are minor (CD less than 3a) and are easily managed. A minority of patients will experience major complications (CD 3a or greater) that require additional procedures and management to secure a safe outcome. These data are helpful to inform patients of the risks of operation and guide physicians for optimal consent. [ABSTRACT FROM AUTHOR]

Background: Delayed gastric emptying (DGE) is a common complication after esophagectomy. BOTOX injections and pyloric surgeries (PS), including pyloroplasty (PP) and pyloromyotomy (PM), are performed intraoperatively as prophylaxis against DGE. This study compares the effects of pyloric BOTOX injection and PS for preventing DGE post-esophagectomy. Methods: We retrospectively reviewed Moffitt's IRB-approved database of 1364 esophagectomies, identifying 475 patients receiving BOTOX or PS during esophageal resection. PS was further divided into PP and PM. Demographics, clinical characteristics, and postoperative outcomes were compared using Chi-Square, Fisher's exact test, Wilcoxon rank-sum, and ANOVA. Propensity-score matching was performed between BOTOX and PP cohorts. Results: 238 patients received BOTOX, 108 received PP, and 129 received PM. Most BOTOX patients underwent fully minimally invasive robotic Ivor-Lewis esophagectomy (81.1% vs 1.7%) while most PS patients underwent hybrid open/Robotic Ivor-Lewis esophagectomy (95.7% vs 13.0%). Anastomotic leak (p = 0.57) and pneumonia (p = 0.75) were comparable between groups. However, PS experienced lower DGE rates (15.9% vs 9.3%; p = 0.04) while BOTOX patients had less postoperative weight loss (9.7 vs 11.45 kg; p = 0.02). After separating PP from PM, leak (p = 0.72) and pneumonia (p = 0.07) rates remained similar. However, PP patients had the lowest DGE incidence (1.9% vs 15.7% vs 15.9%; p = < 0.001) and the highest bile reflux rates (2.8% vs 0% vs 0.4%; p = 0.04). Between matched cohorts of 91 patients, PP had lower DGE rates (18.7% vs 1.1%; p = < 0.001) and less weight loss (9.8 vs 11.4 kg; p = < 0.001). Other complications were comparable (all p > 0.05). BOTOX was consistently associated with shorter LOS compared to PS (all p = < 0.001). Conclusion: PP demonstrates lower rates of DGE in unmatched and matched analyses. Compared to BOTOX, PS is linked to reduced DGE rates. While BOTOX is associated with more favorable LOS, this may be attributable to difference in operative approach. PP improves DGE rates after esophagectomy without improving other postoperative complications. [ABSTRACT FROM AUTHOR]

Introduction: Despite recent attempts to reach a consensus on the diagnostic criteria and treatment of dumping syndrome (DS) after bariatric surgery, many questions about the clinical applicability and significance of standardized provocation tests remain unanswered. The objective of this study was to retrospectively evaluate a mixed-meal-test (MMT) based on general nutritional recommendations after bariatric surgery and its clinical value in diagnosing DS. Methods: The MMT contained 15.5 g of protein, 10 g of fat, 20.7 g of carbohydrates, and 3.1 g of dietary fiber, totaling 241 kcal. Symptoms based on the Sigstad Score, along with blood sugar, hematocrit, pulse rate, and blood pressure, were collected as primary readouts. The analysis included 58 MMTs from 56 patients who reported postprandial symptoms indicative of DS and were referred to the clinic by surgeons or general practitioners. Results: Although all individuals reported significant symptoms at home, the MMT showed a positive symptom score (Sigstad Score ≥7) in only 16 cases (28%). Neither a heart rate increase >10 BPM nor the 3% hematocrit increase suggested as cut-offs for early DS by the consensus paper were associated with the Sigstad Score or individually reported symptoms. None of the participants had a postprandial glucose decrease below 50 mg/dL; one fell below 60 mg/dL and 14 fell below 70 mg/dL. A blood glucose decrease below 70 mg/dL was not associated with symptoms. Conclusion: The MMT showed that only a minority of patients reported classical DS symptoms under controlled conditions. Changes in hematocrit, heart rate, and blood sugar decrease below 70 mg/dL did not help to predict symptoms in the individuals studied. The data, in the context of existing evidence, suggest that provocation tests have little value in clinical practice and that DS as a clinical entity after bariatric surgery should be reevaluated.

Background: This study aimed to provide an overview of minimally invasive and function-preserving surgeries for gastric cancer, focusing on the latest developments in proximal gastrectomy. Current Concepts: Laparoscopic and robotic surgeries have increasingly been adopted as minimally invasive techniques, and pylorus-preserving gastrectomy (PPG) and proximal gastrectomy (PG) have increasingly been performed as function-preserving surgeries. PPG reduces the incidence of dumping syndrome, bile reflux, and gallstones. After PG, there is a high possibility that vitamin B12 injections are not needed. In addition, compared with total gastrectomy, it has the advantages of less anemia, better nutritional status, and secretion of various gastrointestinal hormones. Double-tract reconstruction (DTR) is often performed in PG to prevent reflux esophagitis. In the Korean Laparoendoscopic Gastrointestinal Surgery Study 05 trial, patients who underwent laparoscopic PG with DTR required less vitamin B12 supplementation than those who underwent total gastrectomy, and there was no difference in complication and survival rates. In addition, quality of life, such as physical and social functions, was better. Discussion and Conclusion: PG with DTR can be recognized as function-preserving gastric cancer surgery for patients with upper early gastric cancer. Minimally invasive surgeries such as laparoscopic and robotic procedures have become more common. Function-preserving surgeries now include PPG and PG. Among these, the DTR technique is frequently performed after PG, offering the advantages of preserving vitamin B12 levels and improving the quality of life. [ABSTRACT FROM AUTHOR]

Bariatric surgery is an important weight loss tool in individuals with severe obesity. It is currently the most effective long-term weight loss treatment that lowers obesity-related comorbidities. It also has significant physiological and nutritional consequences that can result in gastrointestinal complications and micronutrient deficiencies. After gastric bypass, clinical events that negatively affect nutritional status include malabsorption, dumping syndrome, kidney stones, altered intestinal bile acid availability, bowel obstruction, ulcers, gastroesophageal reflux, and bacterial overgrowth. Risk factors for poor nutritional status and excessive loss of lean body mass and bone include reduced dietary quality and inadequate intake, altered nutrient absorption, and poor patient compliance with nutrient supplementation. There are unique concerns in adolescents, older individuals, and individuals who become pregnant postoperatively. With careful management, health-care professionals can assist with long-term weight loss success and minimize the risk of acute and long-term nutrition complications after bariatric surgery.

Background: The optimal approach for the safe implementation and education of robotic pancreaticoduodenectomy (RPD) remains unclear. Prolonged operation time may cause surgeon fatigue and result in perioperative complications. To solve this issue, our department adopted task division by the console surgeon turnover between resection and reconstruction in 2022. Methods: This study retrospectively investigated consecutive patients who underwent RPD from November 2009 (initial introduction of RPD) to December 2023. The analysis excluded patients who underwent concomitant resection of other organs. The cases performed by a single console surgeon (single approach) were compared with those performed by two or more console surgeons (multiple approach). Results: This study analyzed 85 consecutive RPD cases, including 51 with the single approach and 34 with the multiple approach. The operation time was significantly shorter (832 vs. 618 min, p < 0.001), and the postoperative major complication was less frequent (45% vs. 12%, p = 0.003) in the multiple approach group, although less experienced surgeons performed the multiple approach (number of RPD experiences: 19 cases vs. 5 cases, p < 0.001). The console surgeon turnover between the resection and reconstruction resulted in a safe pancreatojejunostomy performed by the less experienced surgeon (number of pancreatic reconstruction experiences: 6.5 vs. 14 cases, p = 0.010). Surgeons who started RPD with a multiple approach observed a reduction in surgical time and a lower incidence of complications earlier than those who started with a single approach. Conclusion: Task division during the early introduction phase of RPD using the multiple approach demonstrated potential contributions to improved surgical outcomes and enhanced educational benefits.

Background: Bariatric surgery has been proven to be the most effective therapy for obesity and Roux-en-Y gastric bypass (RYGB) is one of the most commonly performed procedure. However, weight regain and dumping syndrome occur over time. The transoral outlet reduction (TORe) procedure using an endoscopic suturing device may be an option to treat these conditions. We aimed to analyze outcome parameters and long-term results for this endoscopic technique. Methods: A retrospective data analysis of patients who underwent TORe using an endoscopic suturing system at our institution from January 2015 to December 2020 was performed. A total of 71 subjects were included. Forty-five patients received the intervention for weight regain, 9 for dumping syndrome and 17 for both. The primary endpoint was weight stabilization or weight loss for subjects with weight regain, and resolution of symptoms for those with dumping syndrome. Secondary endpoints were intraoperative complications, procedure time, length of hospital stay and diameter of gastrojejunal anastomosis 1 year post-intervention. Results: The median size of the gastrojejunal anastomosis was estimated at 30 mm before intervention, and after performing a median of 3 endoscopic sutures, the median estimated gastrojejunal anastomosis width was reduced to 9.5 mm. Eight perioperative complications occurred. Overall mean follow-up was 26.5 months. All interventions achieved weight stabilization or weight loss or resolution of dumping symptoms within the first 3 months, 98.2% at 12 months, 91.4% at 24 months and 75.0% at 48 months. In 22/26 subjects a persisting improvement of dumping syndrome was achieved. Conclusions: TORe is a safe and effective procedure in the treatment of patients with dumping syndrome after laparoscopic RYGB, the effect on weight stabilization is less significant. A prospective randomized trial should be conducted to compare the effects of TORe with other surgical methods like banding the gastrojejunal anastomosis. [ABSTRACT FROM AUTHOR]

Simple Summary: Immune checkpoint inhibitors (ICIs) offer improved outcomes for patients with various malignancies but they have also been associated with immune-related adverse events. Gastroparesis, a gastrointestinal (GI) motility disorder characterized by delayed gastric emptying (GE) and upper GI symptoms, has been linked to ICIs through histological studies indicating myenteric plexopathy. The aim of our retrospective study was to evaluate the prevalence, clinical course, and treatment for both patients with pre-existing gastroparesis and those with new symptoms of delayed GE after ICI. We found 39 patients with new delayed GE post-ICI (prevalence of 0.2%) and 37 with pre-existing gastroparesis, of which only 4 (11%) had a flare of symptoms post-ICI. We found that delayed GE post-ICI therapy is rare but with late onset and prolonged duration. The presence of alternative etiology of gastroparesis did not affect patients' duration of delayed GE symptoms or overall survival. Immune checkpoint inhibitors (ICIs) can cause myenteric plexopathy, which could result in delayed gastric emptying (GE) and possibly gastroparesis. We assessed the clinical outcomes of patients who had pre-existing gastroparesis or who developed symptoms of delayed GE following ICI therapy. We retrospectively identified adults with ICD-9 and ICD-10 codes for gastroparesis who received ICI therapy between 1 January 2020 and 31 December 2022 at a tertiary cancer center. Of 76 eligible patients, 37 had pre-existing gastroparesis; 39 (0.2% of the more than 18,000 screened) developed symptoms of delayed GE after ICI therapy, of which 27 (69%) patients had an alternative etiology for delayed GE. Four patients (11%) with pre-existing gastroparesis had a flare-up after ICI, and the median time to flare-up was 10.2 months (IQR, 0.7–28.6 months); for patients with new onset of suspected delayed GE after ICI, the median time to symptom onset was 12.8 months (IQR, 4.4–35.5 months). The clinical symptom duration of patients without an alternative etiology (74.5 days (IQR, 21.5–690 days)) and those with an alternative etiology (290 days (IQR, 147–387 days)) did not differ significantly (p = 1.00). Delayed GE after ICI therapy is a rare presentation but has a late onset and a prolonged symptom duration. [ABSTRACT FROM AUTHOR]

Introduction: This study was planned to investigate in-depth patients' experiences with dumping syndrome after total gastrectomy and their self-management in this condition. Method: The research was conducted in a qualitative study design. Data were collected using a face-to-face interview method with patients who underwent total gastrectomy surgery in 2023, using a voice recorder when they came to their outpatient clinic appointments. The interviews were completed in 20–40 ​min. The MAXQDA program was used to analyze the data obtained. The Consolidated Criteria for Reporting Qualitative Research (COREQ) was used as a guide for reporting this study. Results: The study included ten patients who underwent total gastrectomy surgery. The mean age of the patients was 45 years and above. 70% of the patients were male and 30% were female. During the interview with the patients, six main themes and twenty-five sub-themes were formed: 1- Regret about the surgery, 2- Dietary recommendations, 3-Time of complaints, 4- Dietary pattern, 5- What was done for postprandial complaints, 6- Complaints after eating. Conclusion: It is thought that an integrated team-based approach to postoperative care is necessary for patients to gain self-management skills.

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]

Introduction: Post‐bariatric hypoglycaemia (PBH) is a rare yet disabling clinical condition, mostly reported after Roux‐en‐Y gastric bypass (RYGB) surgery. RYGB is one of the most widely used and effective bariatric procedures. The pathophysiology of PBH remains unclear, and treatment options are limited in effectiveness and/or carry significant side effects. Acarbose slows carbohydrates digestion and absorption and is generally considered first‐line pharmacological treatment for PBH but its gastrointestinal side effects limit patient compliance. Canagliflozin inhibits intestinal and renal sodium‐dependent glucose absorption and reduces postprandial excursions of glucose, insulin and incretins after RYGB – effects that could be beneficial in ameliorating PBH. Aims: The trial aims to investigate how blood glucose levels are affected during daily living in subjects with PBH during treatment with canagliflozin or acarbose compared with placebo, and to study the meal‐induced entero‐endocrine mechanisms implied in the treatment responses. Methods: In a double‐blinded, randomized, crossover clinical trial, HypoBar I will investigate the effectiveness in reducing the risk of PBH, safety, ambulatory glucose profile and entero‐endocrine responses when PBH is treated with canagliflozin 300 mg twice daily during a 4‐week intervention period, compared with acarbose 50 mg thrice daily or placebo. Ethics and Dissemination: HypoBar I is approved by the Local regulatory entities. Results will be published in peer‐reviewed journals. Conclusion: If effective, well‐tolerated and safe, canagliflozin could be a novel treatment for people with PBH. HypoBar I might also unravel new mechanisms underlying PBH, potentially identifying new treatment targets. Trial Registration: EudraCT number 2022–000157‐87. [ABSTRACT FROM AUTHOR]

Inflammatory bowel disease (IBD) is a clinical condition of the gastrointestinal tract that has significant incidence in childhood. Major symptoms include abdominal pain, dyspepsia, delayed gastric emptying, anorexia, diarrhea and weight loss. IBD etiopathogenesis is multifactorial, with a proven involvement of cytokines. In this regard, cytokines like resistin and adiponectin produced by adipose tissue play a crucial role in inflammation. Particularly, resistin seems related to IBD severity and is considered a promising marker of disease occurrence and progression. Unraveling its mechanism of action and downstream effectors is mandatory when designing novel therapies. This preclinical study aims to further elucidate the action of resistin in causing functional gastrointestinal alterations, comparing it with the well-defined effect of adiponectin. To this end, we carried out electrophysiological analysis on murine gastric fundus. We found that resistin, similarly to adiponectin, increases smooth muscle cell (SMC) capacitance, indicative of cell surface remodeling, which is consistent with relaxation. However, contrary to adiponectin, resistin unalters membrane potential and inward Ca2+ entry and scarcely affects outward current, suggesting its inefficacy in markedly modifying electrical phenomena on the SMC membrane. This outcome, supporting the role of resistin in gastrointestinal distention, as observed in IBD, rules out a strikingly direct effect on SMCs. [ABSTRACT FROM AUTHOR]

Background: The Upper Digestive Disease (UDD) Tool™ is used to monitor symptom frequency, intensity, and interference across nine symptom domains and includes two Patient-Reported Outcome Measurement Information System (PROMIS) domains assessing physical and mental health. This study aimed to establish cut scores for updated symptom domains through standard setting exercises and evaluate the effectiveness and acceptability of virtual standard setting. Methods: The extended Angoff method was employed to determine cut scores. Subject matter experts refined performance descriptions for symptom control categories and achieved consensus. Domains were categorized into good, moderate, and poor symptom control. Two cut scores were established, differentiating good vs. moderate and moderate vs. poor. Panelists estimated average scores for 100 borderline patients per item. Cut scores were computed based on the sum of the average ratings for individual questions, converted to 0-100 scale. Results: Performance descriptions were refined. Panelists discussed that interpretation of the scores should take into account the timing of symptoms after surgery and patient populations, and the importance of items asking symptom frequency, severity, and interference with daily life. The good/moderate cut scores ranged from 21.3 to 35.0 (mean 28.6, SD 3.6) across domains, and moderate/poor ranged from 47.5 to 71.3 (mean 54.5, SD 7.0). Conclusions: Panelists were confident in the virtual standard setting process, expecting valid cut scores. Future studies can further validate the cut scores using patient perspectives and collect patient and physician preferences for displaying contextual items on patient- and physician-facing dashboard.

Introduction: Bariatric surgery is one of the most effective, safe and indicated interventions for the treatment of obesity. However, despite its benefits, this procedure can cause unwanted complications such as dumping syndrome. In addition, the covid-19 pandemic interfered with the routine of individuals, impacting the health and eating habits of the population, including bariatric patients. Objective: To analyze the association between food consumption and dumping syndrome in bariatric patients in the context of the Covid-19 pandemic. Materials and Methods: This is a cross-sectional, descriptive, analytical, online study with bariatric patients over 18 years old, in the context of the Covid-19 pandemic, data collection was carried out through the application of forms available remotely. Results: The study was carried out with 412 participants, most of them female, with high school education, monthly family income above seven quarters minimum and with more than three years of surgery. A high consumption of fresh foods was observed, however, at the same time there was a high consumption of ultraprocessed foods, in addition to the prevalence of dumping symptoms in the consumption of ultra-processed foods. Conclusion: Dumping syndrome was highly prevalent in bariatric patients, especially in individuals who consume ultra-processed foods. In addition to the composition of food, the symptoms imply eating habits. Finally, the importance of nutritional monitoring for this public is evident. [ABSTRACT FROM AUTHOR]

Introduction: Given the lack of research on the relationship of post-surgery dumping syndrome and eating disturbances, the purpose of the present longitudinal study was to investigate whether dumping after obesity surgery is associated with pre-/postoperative eating disorder symptoms or addiction-like eating beyond the type of surgery, gender, health-realted quality of life (HRQoL) and anxiety/depressive symptoms. Methods: The study included 220 patients (76% women) before (t0) and 6 months after (t1) obesity surgery (sleeve gastrectomy [n = 152], Roux-en-Y gastric bypass [n = 53], omega loop gastric bypass [n = 15]). The Sigstad Dumping Score was used to assess post-surgery dumping syndrome. Participants further answered the Eating Disorder Examination Questionnaire (EDE-Q), Yale Food Addiction Scale 2.0 (YFAS 2.0), Short-Form Health Survey (SF-12), and Hospital Anxiety and Depression Scale (HADS) at t0 and t1. Results: The point prevalence of symptoms suggestive of post-surgery dumping syndrome was 33%. Regression analyses indicate an association of dumping with surgical procedure (bypass), female gender, reduced HRQoL, more anxiety/depressive symptoms, and potentially with binge eating but not with eating disorder symptoms in general or with addiction-like eating. Conclusion: The current study failed to show a close relationship between the presence of self-reported dumping syndrome and eating disorder symptoms or addiction-like eating following obesity surgery. Further studies with longer follow-up periods should make use of clinical interviews to assess psychosocial variables and of objective measures to diagnose dumping in addition to standardized self-ratings.

Post‐bariatric hypoglycaemia (PBH) is a metabolic complication of bariatric surgery (BS), consisting of low post‐prandial glucose levels in patients having undergone bariatric procedures. While BS is currently the most effective and relatively safe treatment for obesity and its complications, the development of PBH can significantly impact patients' quality of life and mental health. The diagnosis of PBH is still challenging, considering the lack of definitive and reliable diagnostic tools, and the fact that this condition is frequently asymptomatic. However, PBH's prevalence is alarming, involving up to 88% of the post‐bariatric population, depending on the diagnostic tool, and this may be underestimated. Given the prevalence of obesity soaring, and an increasing number of bariatric procedures being performed, it is crucial that physicians are skilled to diagnose PBH and promptly treat patients suffering from it. While the milestone of managing this condition is nutritional therapy, growing evidence suggests that old and new pharmacological approaches may be adopted as adjunct therapies for managing this complex condition.

Simple Summary: With ageing, the number of pancreaticoduodenectomies (PD) for benign or malignant disease is expected to increase in elderly patients. The aim of the present meta-analysis is to compare the surgical outcomes of MIPD in elderly versus younger patients. The results of our analysis disclose no considerable differences in terms of technical and post-operative outcomes between the two groups. However, slightly higher, but acceptable, major complication and mortality rates were recorded in the elderly cohort. Although the real additional value of minimally invasive surgery in this frailty subset of patients needs to be further investigated, our findings reveal that MIPD seems to be relatively safe and feasible in elderly patients. (1) Background: With ageing, the number of pancreaticoduodenectomies (PD) for benign or malignant disease is expected to increase in elderly patients. However, whether minimally invasive pancreaticoduodenectomy (MIPD) should be performed in the elderly is not clear yet and it is still debated. (2) Materials and Methods: A systematic review and meta-analysis was conducted including seven published articles comparing the technical and post-operative outcomes of MIPD in elderly versus younger patients up to December 2022. (3) Results: In total, 1378 patients were included in the meta-analysis. In term of overall and Clavien–Dindo I/II complication rates, post-operative pancreatic fistula (POPF) grade > A rates and biliary leakage, abdominal collection, post-operative bleeding and delayed gastric emptying rates, no differences emerged between the two groups. However, this study showed slightly higher intraoperative blood loss [MD 43.41, (95%CI 14.45, 72.38) p = 0.003], Clavien–Dindo ≥ III complication rates [OR 1.87, (95%CI 1.13, 3.11) p = 0.02] and mortality rates [OR 2.61, (95%CI 1.20, 5.68) p = 0.02] in the elderly compared with the younger group. Interestingly, as a minor endpoint, no differences in terms of the mean number of harvested lymphnode and of R0 resection rates were found. (4) Conclusion: MIPD seems to be relatively safe; however, there are slightly higher major morbidity, lung complication and mortality rates in elderly patients, who potentially represent the individuals that may benefit the most from the minimally invasive approach.

Abdominal pain and postbariatric hypoglycemia (PBH) are common after bariatric surgery. This study aimed to explore the potential relationship between abdominal pain, gastrointestinal symptoms, and PBH more than a decade after Roux-en-Y gastric bypass (RYGB) and whether continuous glucose monitoring (CGM) with dietary intervention has an educational role in reducing symptoms. At two public hospitals in Norway (one University Hospital) 22 of 46 invited patients who reported abdominal pain more than weekly took part. Recruited from a prospective follow-up study of 546 patients 14.5 years after RYGB. They used a CGM for two 14-day periods, with a dietary intervention between periods. The Gastrointestinal Symptom Rating Scale (GSRS) and the Dumping Severity Score (DSS) questionnaires were completed at the start and end of the study. The 22 women had preoperative age 39.6 ± 7.7 years and body mass index (BMI) 42.0 ± 4.0 kg/m2, present age 54.6 ± 7.7 years and BMI 29.8 ± 4.8 kg/m2. The total GSRS score and DSS of early dumping decreased after the diet intervention. The number of events with Level 1 (<3.9 mmol/L) or Level 2 (<3.0 mmol/L) hypoglycemia did not change in the second period. Half of the patients had fewer, three had unchanged, and eight had more frequent events with Level 1 hypoglycemia after the intervention. Ten patients had Level 2 hypoglycemia. Though inconclusive findings, a personalized dietary intervention reduces GSRS. This intervention was accompanied by lower mean absolute glucose in patients with recurrent abdominal pain after bariatric surgery. However, further studies are needed to explore the benefits of CGM in this setting. [Display omitted] • CGM may be a first step to evaluating glycemic fluctuations and abdominal pain. • Half of the patients with abdominal pain more than weekly also suffered from PBH. • Patients had lower total GSRS and score of indigestion after diet intervention. • DSS score of early dumping was lower after diet intervention. • CGM adds value to patient involvement to comply with the recommended dietary advice.

This narrative review describes the clinical syndrome, pathophysiology, diagnosis and reports on standard and pragmatic therapeutical treatment options in order to improve the clinical outcome of patients with dumping syndrome. Dumping syndrome consists of early and late dumping symptoms and can be diagnosed using clinical parameters with the help of the Sigstad’s score, questionnaires or by provocative testing. The prevalence of dumping syndrome varies depending on the employed definition of dumping syndrome. Overall, dumping syndrome is more frequent nowadays due to increasing numbers of upper gastrointestinal and bariatric surgeries being performed. First treatment step includes dietary adjustment and dietary supplements, which are often sufficient to manage symptoms for the majority of patients. Next step of therapy includes acarbose, which is effective for late dumping symptoms, but the use is limited due to side effects. Somatostatin analogues are indicated after these two steps have failed. Somatostatin analogues are very effective for controlling early and late dumping, also in the long term. Glucagon like peptide-1 receptor agonists, endoscopic and surgical (re)interventions are reported as treatment options for refractory dumping syndrome; however, their use is not recommended in clinical practice due to the limited evidence on and uncertainty of outcomes. These alternatives should be considered only as last resort options in patients with otherwise refractory and invalidating dumping syndrome.Keywords: dumping syndrome, early and late dumping, somatostatin analogues, octreotide, bariatric surgery, upper gastrointestinal surgery

Esophagectomy is a technically complex operation performed for both benign and malignant esophageal disease. Medical and surgical advancements have led to improved outcomes in esophagectomy patients over the past several decades; however, surgeons must remain vigilant as complications happen often and can be severe. Post-esophagectomy complications can be grouped into early and late categories. The aim of this review is to discuss the early complications of esophagectomy along with their risk factors, work-up, and management strategies with special attention given to anastomotic leaks.

Background: Post-prandial hypoglycemia is an uncommon but disabling late complication of Roux-en-Y gastric bypass (RYGB). Most patients can be treated with dietary interventions and medications; however, some patients develop refractory hypoglycemia that may lead to multiple daily episodes and seizures. While RYGB reversal surgery is an effective treatment, complication rates are high, and patients inevitably experience weight regain. Transoral gastric outlet reduction (TORe) is a minimally invasive treatment that is effective for early and late dumping syndrome. However, prior studies have not distinguished the effectiveness of TORe specifically for patients with post-prandial hypoglycemia. This study aims to describe a single institution's experience of TORe for treating post-prandial hypoglycemia. Methods: This is a case series of patients with prior RYGB complicated by post-prandial hypoglycemia who underwent TORe from February 2020 to September 2021. Pre-procedural characteristics and post-procedural outcomes were obtained. Outcomes assessed included post-prandial hypoglycemia episodes, dumping syndrome symptoms, and weight change. Results: A total of 11 patients underwent TORe from 2020 to 2021 for post-prandial hypoglycemia. Three (27%) patients had a history of seizures due to hypoglycemia. All had been advised on dietary changes, and ten patients (91%) were on medications for dumping. All patients reported a reduction in post-prandial hypoglycemic events as well as the majority of dumping syndrome symptoms during an average follow-up time of 409 ± 125 days. Ten patients (91%) had experienced weight regain from their post-RYGB nadir weight. For these patients, the average total body weight loss 12 months post-TORe was 12.4 ± 12%. There were no complications requiring hospitalization. One patient experienced post-TORe nausea and vomiting requiring dilation of the gastrojejunal anastomosis with resolution in symptoms. Conclusion: TORe is a safe and effective treatment for post-prandial hypoglycemia and weight regain after RYGB in patients with symptoms refractory to medications and dietary changes.

Background and Purpose: Dumping syndrome (DS) is a shared but underappreciated complication after metabolic-bariatric surgery. The purpose of the study was to investigate the prevalence and intensity of symptoms suggestive of DS and their relationship with health-related quality of life (HRQOL) after laparoscopic sleeve gastrectomy (LSG). Method: A retrospective cohort study was performed for all patients with a history of sleeve gastrectomy between July 2017 and July 2022 in our center. Basial clinic statistics were gathered from electronic medical database, the prevalence and severity of DS were assessed by Dumping Symptom Rating Scale (DSRS), and HRQOL is collected through the Short Form Health Survey 36 (SF-36). Result: In total, 133 of 202 patients completed the questionnaire (response rate 65.8%). A total of 64.7% (N = 86) of participants were female, aged 34.0 (IQR 26.0–39.0) years at completion of the questionnaire, with a mean body mass index of 35.8 (IQR 31.4–40.5) kg/m2. The prevalence of symptoms suggestive of DS was 45.9% (N = 61), and the associated protective factor was the time between surgery and study. Compared with the patients without DS, patients with DS scored significantly worse on four of eight SF-36 subdomains. Conclusion: Symptoms suggestive of early dumping syndrome after sleeve gastrectomy are common and are associated with a worse health-related quality of life, which deserves clinical attention. Additional counselling, education, and care are needed to mitigate the decline in quality of life caused by dumping symptoms. [ABSTRACT FROM AUTHOR]

This article explores the connection between bariatric surgery and ongoing multidisciplinary care for individuals with obesity. The authors stress the importance of thorough preparation before surgery and continued postoperative care for optimal results. They also address the growing prevalence of bariatric surgery and the potential challenges related to accreditation, multidisciplinary care, and follow-up with primary care doctors. The authors propose that primary care physicians should be knowledgeable about bariatric care to provide comprehensive support to patients. Additionally, the article discusses the complexity of measuring obesity and advocates for the use of person-first language to reduce stigma. Another article in the journal Nature Medicine focuses on weight stigma in healthcare settings and its negative impact on health. The author argues that eliminating weight stigma is crucial for improving patient outcomes. The article takes a perspective that acknowledges the harmful effects of weight stigma and calls for a more inclusive and respectful approach to healthcare. [Extracted from the article]

Dumping syndrome after bariatric surgery is common. However, it is rarely seen during pregnancy because patients are usually advised to avoid pregnancy immediately after surgery. This case highlights the importance of avoidance of pregnancy after bariatric surgery. We report a case of unplanned pregnancy in a 35-year-old woman with a history of subfertility for 8 years who conceived spontaneously 3 months after gastric bypass surgery. This occurred because there was no contraception offered to her after the procedure. The pregnancy was complicated with recurrent episodes of hypoglycaemia secondary to dumping syndrome. Primary care providers need to be vigilant and have a high index of suspicion for dumping syndrome in pregnant obese women who have undergone bariatric surgery. [ABSTRACT FROM AUTHOR]

Background: The current design of biliopancreatic diversion with duodenal switch (BPD/DS) and single anastomosis duodenal–ileal bypass with sleeve (SADI-S) emphasizes the importance of the pylorus' preservation to reduce the incidence of marginal ulcer (MU) and dumping. However, no institutional studies have yet reported data on their prevalence. We aimed to assess the incidence of MU and dumping after duodenal switch (DS) and identify the associative factors. Methods: A multi-center review of patients who underwent BPD/DS or SADI-S between 2008 and 2022. Baseline demographics, symptoms, and management of both complications were collected. Fisher's exact test was used for categorical variables and the independent t-test for continuous variables. Results: A total of 919 patients were included (74.6% female; age 42.5 years; BMI 54.6 kg/m2) with mean follow-up of 31.5 months. Eight patients (0.9%) developed MU and seven (0.8%) had dumping. Patients who developed MU were more likely to be using non-steroidal anti-inflammatory drugs (NSAID) (p = 0.006) and have a longer operation time (p = 0.047). Primary versus revisional surgery, and BDP/DS versus SADI-S were not associated with MU or dumping. Conclusions: The incidences of MU and dumping after DS were low. NSAID use and a longer operation time were associated with an increased risk of MU, whereas dumping was attributed to poor dietary habits. [ABSTRACT FROM AUTHOR]

Summary: Background: The Dumping syndrome occurs in a variable percentage of subjects undergoing surgery involving the esophageal and gastric district. The treatment makes use of the introduction of dietary measures and artificial nutrition, especially the internal one. This study evaluates the experience of a single center regarding the use of percutaneous endoscopic jejunostomy (PEJ) in patients developing the dumping syndrome. Methods: We evaluated the case history of our department, of all patients operated on at the level of the upper gastrointestinal tract, who had manifested symptoms referable to the Dumping syndrome in the postoperative period. We have identified 3, which we have carried out further investigations to confirm the presence of an accelerated gastric emptying, and given the poor results obtained with dietary modifications and drug therapy, we have implemented a feeding through enteral nutrition, through a jejunal probe. PEG/J positioned by Pull technique, and subsequently replaced after 8 months. Results: Clinically, patients did not develop short- or long-term complications, symptoms were significantly reduced, and they gained weight. Psychologically, the anxiety disorders related to nutrition have improved. Conclusions: By means of percutaneous endoscopic jejunostomy, the symptoms related to hypoglycemic crises following the hyperinsulinemic response to the ingestion of carbohydrates in patients with Dumping were attenuated and the anxiety of eating was lessened. Although limited to a few cases, we believe this form of nutrition is the best for patients with dumping.

Background: Prior work supports delayed gastric emptying in anorexia nervosa and bulimia nervosa (BN) but not binge-eating disorder, suggesting that neither low body weight nor binge eating fully accounts for slowed gastric motility. Specifying a link between delayed gastric emptying and self-induced vomiting could offer new insights into the pathophysiology of purging disorder (PD). Methods: Women (N = 95) recruited from the community meeting criteria for DSM-5 BN who purged (n = 26), BN with nonpurging compensatory behaviors (n = 18), PD (n = 25), or healthy control women (n = 26) completed assessments of gastric emptying, gut peptides, and subjective responses over the course of a standardized test meal under two conditions administered in a double-blind, crossover sequence: placebo and 10 mg of metoclopramide. Results: Delayed gastric emptying was associated with purging with no main or moderating effects of binge eating in the placebo condition. Medication eliminated group differences in gastric emptying but did not alter group differences in reported gastrointestinal distress. Exploratory analyses revealed that medication caused increased postprandial PYY release, which predicted elevated gastrointestinal distress. Conclusions: Delayed gastric emptying demonstrates a specific association with purging behaviors. However, correcting disruptions in gastric emptying may exacerbate disruptions in gut peptide responses specifically linked to the presence of purging after normal amounts of food.

Background: Both weight regain and dumping syndrome (DS) after Roux-en-Y gastric bypass (RYGB) have been related to the dilation of gastro-jejunal anastomosis. The aim of this study is to assess the safety and long-term efficacy of endoscopic transoral outlet reduction (TORe) for DS and/or weight regain after RYBG. Materials and Methods: A retrospective analysis was performed on a prospective database. Sigstad's score, early and late Arts Dumping Score (ADS) questionnaires, absolute weight loss (AWL), percentage of total body weight loss (%TBWL), and percentage of excess weight loss (%EWL) were assessed at baseline and at 6, 12, and 24 months after TORe. Results: Eighty-seven patients (median age 46 years, 79% female) underwent TORe. The median baseline BMI was 36.2 kg/m2. Out of 87 patients, 58 were classified as "dumpers" due to Sigstad's score ≥ 7. The resolution rate of DS (Sigstad's score < 7) was 68.9%, 66.7%, and 57.2% at 6, 12, and 24 months after TORe, respectively. A significant decrease in Sigstad's score as well as in early and late ADS questionnaires was observed (p < 0.001). The median Sigstad's score dropped from 15 (11–8.5) pre-operatively to 2 (0–12) at 24 months. The %TBWL was 10.5%, 9.9%, and 8.1% at 6, 12, and 24 months, respectively. Further, "dumpers" with resolution of DS showed better weight loss results compared with those with persistent DS (p < 0.001). The only adverse event observed was a perigastric fluid collection successfully managed conservatively. Conclusion: TORe is a minimally invasive treatment for DS and/or weight regain after RYGB, with evidence of long-term efficacy. [ABSTRACT FROM AUTHOR]

Hypoglycaemia is diagnosed by the presence of symptoms of hypoglycaemia, documented low plasma glucose (often less than 50 mg/dl) at the time of symptoms, and recovery of symptoms by correction of glucose. If plasma glucose is normal at the time of symptoms, causes other than hypoglycaemia should be considered. If hypoglycaemia has been documented, the cause of hypoglycaemia should be investigated. Only after documentation of spontaneous endogenous insulin secretion causing hypoglycaemia should we proceed with localization of the tumor. Surgery will cure hypoglycaemia in about 90% of patients with insulinoma. Dumping syndrome can cause postprandial symptoms in people who have had upper gastrointestinal (GI) surgery (and rarely without surgery). The symptom complex in dumping syndrome includes the ones caused by GI stretching and GI hormones, or hypoglycaemia, or both. Dumping syndrome often needs to be managed by dietary interventions with or without pharmacotherapy.

Postprandial reactive hypoglycemia, or late dumping syndrome, is a common but underrecognized complication from bypass surgery. We report an unusual case of postprandial reactive hypoglycemia in a patient with a severe esophageal stricture from corrosive agent ingestion who underwent ileocolic interposition and an antecolic Billroth‐II gastrojejunostomy. A 22‐year‐old male patient with a one‐year history of corrosive ingestion was referred to the hospital for a surgical correction of severe esophageal stricture. After the patient underwent ileocolic interposition and an antecolic Billroth‐II gastrojejunostomy, he experienced multiple episodes of gastroesophageal refluxsymptoms during nasogastric feeding and had onset of hypoglycemic symptoms. His plasma glucose level was 59 mg/dL. After we had intraoperatively re‐inserted a jejunostomy tube bypassing the ileocolic interposition, and reintroduced enteral nutrition, his hypoglycemic symptoms resolved. We performed a mixed meal tolerance test by nasogastric tube, but the results did not show postprandial hypoglycemia. Although the specific mechanism is unclear, this case suggests gastroesophageal reflux to the ileal interposition may have caused a state of exaggerated hyperinsulinemic response and rebound hypoglycemia. To the best of our knowledge, we are the first to report case of postprandial hypoglycemia after ileocolic interposition, which may have been caused by exaggerated hyperinsulinemic response due to gastroesophageal reflux to the ileal interposition. This syndrome should be considered in the patient who has had ileocolic interposition surgery and has developed postprandial hypoglycemia. [ABSTRACT FROM AUTHOR]

Purpose: The present research was conducted to evaluate the effect of the severity of dumping syndrome (DS) on weight loss outcomes after Roux-en-Y gastric bypass (RYGB) in patients with class III obesity. Methods: The present retrospective cohort study used the dumping symptom rating scale (DSRS) to evaluate the severity of DS and its correlation with weight loss outcomes in 207 patients 1 year after their RYGB. The patients were assigned to group A with mild-to-moderate DS or group B with severe DS. Results: The mean age of the patients was 42.18 ± 10.46 years and their mean preoperative BMI 42.74 ± 5.59 kg/m2. The total weight loss percentage (%TWL) in group B was insignificantly higher than that in group A, but besides that was not significantly different in the two groups. Conclusion: The present findings suggested insignificant relationships between the presence and severity of DS after RYGB and adequate postoperative weight loss. [ABSTRACT FROM AUTHOR]
