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/m. 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.

Review
Obesity is a chronic relapsing disease of global pandemic proportions. In this context, an increasing number of patients are undergoing bariatric surgery, which is considered the most effective weight loss treatment for long-term improvement in obesity-related comorbidities. One of the most popular bariatric surgeries is the Roux-en-Y gastric bypass (RYGB). Despite its proven short- and long-term efficacy, progressive weight regain and dumping symptoms remain a challenge. Revisional bariatric surgery is indicated when dietary and lifestyle modification, pharmaceutical agents and/or psychological therapy fail to arrest weight regain or control dumping. However, these re-interventions present greater technical difficulty and are accompanied by an increased risk of peri- and postoperative complications with substantial morbidity and mortality. The endoscopic approach to gastrojejunal anastomotic revision, transoral outlet reduction (TORe), is used as a minimally invasive treatment that aims to reduce the diameter of the gastrojejunal anastomosis, delaying gastric emptying and increasing satiety. With substantial published data supporting its use, TORe is an effective and safe bariatric endoscopic technique for addressing weight regain and dumping syndrome after RYGB.

Background Bariatric surgery is one of the most effective interventions for morbid obesity. Despite its benefits, unwanted consequences such as dumping syndrome (DS) have been reported following the procedure. This study aims to estimate the prevalence of DS and identify the factors associated with it in Saudi Arabia. Methodology This cross-sectional study collected data from patients who underwent bariatric surgery at King Fahad General Hospital, Jeddah, Saudi Arabia, in 2019-2020. A validated questionnaire was used to collect the data. The questionnaire included demographic items such as age and sex and items relating to DS such as nausea, vomiting, and palpitations. A modified version of the Sigstad diagnostic scoring system was used to confirm the diagnosis. Results Of the 240 investigated cases, two-thirds (67.5%) were females. The most reported symptoms were nausea (37.9%), vomiting (36.7%), desire to lie down (25.5%), restlessness (25.5%), and abdominal fullness (23.7%). Based on the modified Sigstad diagnostic scoring system, 75 (31.4%) patients met the criteria for DS. The bivariate analysis showed the prevalence was significantly higher in females (36.4%), those with university qualifications (40.3%), and those with high monthly income (62.5%) (p<0.05). Also, dietary behaviors in terms of frequency, size of meals, and drinking liquids with meals were significantly associated with the prevalence of DS, where the lowest prevalence was recorded among those who ate more than one small meal (10.9%), while the highest prevalence was found in those who ate more than one large meal (81.8%); also, the prevalence was significantly higher in patients who drank liquids with meals (40.8%) than those who drank liquids between meals (26.8%) (p<0.05). Conclusion In this single institutional study, we report a 31.4% prevalence of DS among our cohort. The predictors of the syndrome include gender, education level, monthly income, eating more than one large meal per day, and drinking liquids with meals. In the future, these predictors will be explained to patients before and after bariatric surgery to reduce the prevalence of such inconvenient syndromes.

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/m. 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.

Robotic surgery is increasingly gaining importance. While initial results suggest an advantage of the robotic over the minimally invasive approach in patients with gastric cancer, definitive proof of its superiority has yet to be provided. There are numerous approaches to recreate a gastric reservoir after a total gastrectomy. However, a major disadvantage of most conventional reconstructions are long term effects such as dumping syndrome, afferent loop syndrome and poor nutrition intake with severe impact on the patient quality of life. The jejunal pouch reconstruction is a beneficial reconstruction, which provides a larger reservoir capacity after gastrectomy and prevents anastomotic stenosis and dumping syndrome. The completely intercorporeal approach with a Pfannenstiel incision instead of an unfavorable midline incision can potentially decrease delayed complications such as incision hernias. With the increased deployment of robotic surgery, a complete intercorporeal reconstruction is now possible without major increase in operating time or further technical weak points. We provide for the first time a detailed technical explanation of the completely intercorporeal robotic jejunal pouch reconstruction after gastrectomy.

Review
Over the past 30 years, the prevalence of upper third gastric cancer (GC) and gastroesophageal junction (GEJ) cancer has increased. Total gastrectomy with D2 lymph node dissection is the standard surgical treatment for non-early (T2 or higher) upper third and GEJ cancers, but total gastrectomy often results in post-gastrectomy syndrome (5-50%), consisting of weight loss, dumping syndrome, and anemia. Proximal gastrectomy (PG) has the potential to avoid these postoperative problems by preserving stomach function. However, PG has historically been discouraged by surgeons owing to the high incidence of postoperative reflux esophagitis (20-65%), anastomotic stenosis, and decreased quality of life. In recent years, anti-reflux reconstruction techniques, such as the double flap technique and double-tract reconstruction, have been developed to be performed after PG, and evidence has emerged that these techniques not only reduce the incidence of postoperative reflux esophagitis but also decrease postoperative weight loss and prevent anemia. Prospective studies are underway to determine whether PG with anti-reflux techniques improves patient-reported quality of life. In the present work, we reviewed available evidence for the use of PG for GC and GEJ cancer, including oncologically appropriate patient selection for PG, potential functional benefits of PG over TG, and various types of reconstructions that can be performed after PG, as well as future research on the use of PG.

Review
Obesity is a chronic, relapsing disease representing a global epidemic. To date, bariatric surgery is the most effective treatment for morbid obesity in the long-term. Roux-en-Y gastric bypass (RYGB) is one of the most performed bariatric interventions, with excellent long-term outcomes. However, about one-third of patients may experience weight regain over time, as well as dumping syndrome. Both these conditions are challenging to manage and require a multidisciplinary and personalized approach. The dilation of the gastro-jejunal anastomosis is a recognized etiological factor for both weight regain and dumping syndrome. Dietary modifications, behavioral interventions, and medications represent the first therapeutic step. Revisional surgery is the traditional approach when non-invasive treatments fail. However, re-interventions may be technically difficult and are associated with increased morbidity and mortality. Transoral outlet reduction (TORe) is an endoscopic procedure aimed at reducing the size of the anastomosis and is proposed as a minimally invasive treatment of weight regain and/or dumping syndrome refractory to conservative therapies. This review is aimed at providing a narrative overview of the role of TORe as part of the multidisciplinary therapeutic toolkit nowadays available to approach weight regain and dumping syndrome after RYGB.

BACKGROUND
Gastric per oral endoscopic esophageal myotomy (G-POEM) is a promising procedure to treat refractory gastroparesis. The safety profile of G-POEM is an important topic because gastroparesis is a functional pathology, with a procedure whose effectiveness is between 50 and 65% depending on the studies.
OBJECTIVES
We present this retrospective multicenter study, with the aim of establishing a safety profile, focusing on serious adverse events (AEs).
DESIGN
This was a multicenter observational cohort study conducted in five French expert centers.
METHODS
All patients who underwent G-POEM for refractory gastroparesis between 2015 and 2021 were included for analysis. AEs were classified into per endoscopic, early postoperative, and late postoperative, up to 1 month. Their severity was assessed using Dindo-Clavien and American Society for Gastrointestinal Endoscopy classification. The primary objective was to evaluate the rate of G-POEM severe AEs. Secondary objectives were to document other postoperative AEs, and to identify predictive factors.
RESULTS
In all, 217 patients were included: 81 men and 136 women, mean age 52 ± 17 years. The average procedural time was 44 ± 14 min (12-78). The average hospital stay was 3.7 ± 2.3 days. The AEs rate classified as Clavien-Dindo ⩾3 was 0.4% (one delayed bleeding requiring blood transfusion and endoscopic management). There were no deaths or patients admitted to intensive care unit. The rates of mucosotomy and capnoperitoneum were 3.7 and 1.8%, respectively, without clinical consequences. Most patients (81.5%) did not experience any AE. Three cases of dumping syndrome occurred, quickly managed by dietary measures.
CONCLUSION
Our study confirms the safety of G-POEM with less than 0.5% of serious AEs, medically managed. This outcome makes this a procedure to have a good benefit-risk ratio.

Meta-Analysis
BACKGROUND
Pylorus-preserving gastrectomy (PPG) is a function-preserving surgery for the treatment of early gastric cancer (EGC) in the middle third of the stomach. According to the literature reports, PPG decreases the incidence of dumping syndrome, bile reflux, gallstone formation, and nutritional deficit compared with conventional distal gastrectomy (CDG). However, the debates about PPG have been dominated by the incomplete lymphadenectomy and oncological safety. We carried out a systematic review and meta-analysis to evaluate the pathological and oncological outcomes of PPG.
METHODS
The protocol was registered in PROSPERO under number CRD42022304677. Databases including PubMed, Embase, Web of Science, and the Cochrane Register of Controlled Trials were searched before February 21, 2022. The outcomes included the pooled odds ratios (ORs) for dichotomous variables and weighted mean differences (WMDs) for continuous variables. For all outcomes, 95% confidence intervals (CIs) were calculated. Meta-analysis was performed using STATA software (Stata 14, Stata Corporation, Texas) and Review Manager 5.4.
RESULTS
A total of 4500 patients from 16 studies were included. Compared with the CDG group, the PPG group had fewer lymph nodes harvested (WMD= -3.09; 95% CI -4.75 to -1.43; P < 0.001). Differences in the number of resected lymph nodes were observed at stations No. 5, No. 6, No. 9, and No. 11p. There were no differences in lymph node metastasis at each station. Shorter proximal resection margins (WMD = -0.554; 95% CI -0.999 to -0.108; P = 0.015) and distal resection margins (WMD = -1.569; 95% CI -3.132 to -0.007; P = 0.049) were observed in the PPG group. There were no significant differences in pathological T1a stage (OR = 0.99; 95% CI 0.80 to 1.23; P = 0.88), T1b stage (OR = 1.01; 95% CI 0.81 to 1.26; P = 0.88), N0 stage (OR = 0.97; 95% CI 0.63 to 1.48; P = 0.88), tumor size (WMD = -0.10; 95% CI -0.25 to 0.05; P = 0.187), differentiated carcinoma (OR = 1.04; 95% CI 0.74 to 1.47; P = 0.812) or signet ring cell carcinoma (OR = 1.22; 95% CI 0.90 to 1.64; P = 0.198). No significant differences were observed between the groups in terms of overall survival (HR = 0.63; 95% CI 0.24 to 1.67; P = 0.852) or recurrence-free survival (HR = 0.29; 95% CI 0.03 to 2.67; P = 0.900).
CONCLUSIONS
The meta-analysis of existing evidence demonstrated that the survival outcomes of PPG may be comparable to those of CDG. However, fewer lymph nodes at stations in No. 5, No. 6, No. 9, and No. 11p were harvested with PPG. We also found shorter proximal resection margins and distal resection margins for PPG, meaning more remnant stomachs would be preserved in PPG.

Effect of modified esophagectomy perioperative technique resection for patients with locally advanced esophageal cancer (tumor length > 8 cm): initial experience in 45 cases.
BACKGROUND
Patients with locally advanced esophageal cancer with a lesion length greater than 8 cm (LCWEC) are prone to high mortality in a short time due to esophagotracheal fistula (ETF) and esophagoaortic fistula (EAF). We tried to explore a safe salvage surgical method during the perioperative period to maximize the resection of the tumor on the premise of safety and reconstruction of the alimentary tract to avoid early death due to ETF and EAF.
METHODS
From December 2007 to November 2018, forty-five LCWEC patients were treated using the modified Wu's esophagectomy. Patient features, surgical techniques, postoperative complications, and pathology outcomes were analyzed.
RESULTS
The average length of the tumors was 12.5 cm (range 8.1-22.5 cm), and the average transverse tumor diameter was 5.8 cm (range 4.5-7.8 cm). No complications like anastomotic leakage, anastomotic stenosis, chylothorax, delayed gastric emptying, vocal cord paralysis, dumping syndrome, and reflux were detected. The 30-day and in-hospital mortality rates were 0%. Complete (R0) resection was achieved in 38 (84.4%) cases. The resection margin rate of positive anastomosis was 0%. Until the death of the patients, no feeding failure due to gastrointestinal obstruction and early death due to ETF or EAF occurrence. During follow-up, the median time to death was 17.2 months for patients treated with surgery alone and 32 months for patients treated with postoperative multimodal treatment.
CONCLUSION
The modified Wu's esophagectomy is a safe and feasible salvage surgical method for LCWEC resection.
