Uncut Roux-en-Y reconstruction after distal gastrectomy for gastric cancer.

BACKGROUND: Choosing an optimal reconstruction method is pivotal for patients with gastric cancer undergoing distal gastrectomy. The uncut Roux-en-Y reconstruction, a variant of the conventional Roux-en-Y approach (or variant of the Billroth II reconstruction), employs uncut devices to occlude the afferent loop of the jejunum. This modification is designed to mitigate postgastrectomy syndrome and enhance long-term functional outcomes. However, the comparative benefits and potential harms of this approach compared to other reconstruction techniques remain a topic of debate. OBJECTIVES: To assess the benefits and harms of uncut Roux-en-Y reconstruction after distal gastrectomy in patients with gastric cancer. SEARCH METHODS: We searched CENTRAL, PubMed, Embase, WanFang Data, China National Knowledge Infrastructure, and clinical trial registries for published and unpublished trials up to November 2023. We also manually reviewed references from relevant systematic reviews identified by our search. We did not impose any language restrictions. SELECTION CRITERIA: We included randomised controlled trials (RCTs) and quasi-RCTs comparing uncut Roux-en-Y reconstruction versus other reconstructions after distal gastrectomy for gastric cancer. The comparison groups encompassed other reconstructions such as Billroth I, Billroth II (with or without Braun anastomosis), and Roux-en-Y reconstruction. DATA COLLECTION AND ANALYSIS: We used standard Cochrane methodological procedures. The critical outcomes included health-related quality of life at least six months after surgery, major postoperative complications within 30 days after surgery according to the Clavien-Dindo Classification (grades III to V), anastomotic leakage within 30 days, changes in body weight (kg) at least six months after surgery, and incidence of bile reflux, remnant gastritis, and oesophagitis at least six months after surgery. We used the GRADE approach to evaluate the certainty of the evidence. MAIN RESULTS: We identified eight trials, including 1167 participants, which contributed data to our meta-analyses. These trials were exclusively conducted in East Asian countries, predominantly in China. The studies varied in the types of uncut devices used, ranging from 2- to 6-row linear staplers to suture lines. The follow-up periods for long-term outcomes spanned from 3 months to 42 months, with most studies focusing on a 6- to 12-month range. We rated the certainty of evidence from low to very low. Uncut Roux-en-Y reconstruction versus Billroth II reconstruction In the realm of surgical complications, very low-certainty evidence suggests that uncut Roux-en-Y reconstruction compared with Billroth II reconstruction may make little to no difference to major postoperative complications (risk ratio (RR) 0.98, 95% confidence interval (CI) 0.24 to 4.05; I² = 0%; risk difference (RD) 0.00, 95% CI -0.04 to 0.04; I² = 0%; 2 studies, 282 participants; very low-certainty evidence) and incidence of anastomotic leakage (RR 0.64, 95% CI 0.29 to 1.44; I² not applicable; RD -0.00, 95% CI -0.03 to 0.02; I² = 32%; 3 studies, 615 participants; very low-certainty evidence). We are very uncertain about these results. Focusing on long-term outcomes, low- to very low-certainty evidence suggests that uncut Roux-en-Y reconstruction compared with Billroth II reconstruction may make little to no difference to changes in body weight (mean difference (MD) 0.04 kg, 95% CI -0.84 to 0.92 kg; I² = 0%; 2 studies, 233 participants; low-certainty evidence), may reduce the incidence of bile reflux into the remnant stomach (RR 0.67, 95% CI 0.55 to 0.83; RD -0.29, 95% CI -0.43 to -0.16; number needed to treat for an additional beneficial outcome (NNTB) 4, 95% CI 3 to 7; 1 study, 141 participants; low-certainty evidence), and may have little or no effect on the incidence of remnant gastritis (RR 0.27, 95% CI 0.01 to 5.06; I2 = 78%; RD -0.15, 95% CI -0.23 to -0.07; I2 = 0%; NNTB 7, 95% CI 5 to 15; 2 studies, 265 participants; very low-certainty evidence). No studies reported on quality of life or the incidence of oesophagitis. Uncut Roux-en-Y reconstruction versus Roux-en-Y reconstruction In the realm of surgical complications, very low-certainty evidence suggests that uncut Roux-en-Y reconstruction compared with Roux-en-Y reconstruction may make little to no difference to major postoperative complications (RR 4.74, 95% CI 0.23 to 97.08; I² not applicable; RD 0.01, 95% CI -0.02 to 0.04; I² = 0%; 2 studies, 256 participants; very low-certainty evidence) and incidence of anastomotic leakage (RR 0.34, 95% CI 0.05 to 2.08; I² = 0%; RD -0.02, 95% CI -0.06 to 0.02; I² = 0%; 2 studies, 213 participants; very low-certainty evidence). We are very uncertain about these results. Focusing on long-term outcomes, very low-certainty evidence suggests that uncut Roux-en-Y reconstruction compared with Roux-en-Y reconstruction may increase the incidence of bile reflux into the remnant stomach (RR 10.74, 95% CI 3.52 to 32.76; RD 0.57, 95% CI 0.43 to 0.71; NNT for an additional harmful outcome (NNTH) 2, 95% CI 2 to 3; 1 study, 108 participants; very low-certainty evidence) and may make little to no difference to the incidence of remnant gastritis (RR 1.18, 95% CI 0.69 to 2.01; I² = 60%; RD 0.03, 95% CI -0.03 to 0.08; I² = 0%; 3 studies, 361 participants; very low-certainty evidence) and incidence of oesophagitis (RR 0.82, 95% CI 0.53 to 1.26; I² = 0%; RD -0.02, 95% CI -0.07 to 0.03; I² = 0%; 3 studies, 361 participants; very low-certainty evidence). We are very uncertain about these results. Data were insufficient to assess the impact on quality of life and changes in body weight. AUTHORS' CONCLUSIONS: Given the predominance of low- to very low-certainty evidence, this Cochrane review faces challenges in providing definitive clinical guidance. We found the majority of critical outcomes may be comparable between the uncut Roux-en-Y reconstruction and other methods, but we are very uncertain about most of these results. Nevertheless, it indicates that uncut Roux-en-Y reconstruction may reduce the incidence of bile reflux compared to Billroth-II reconstruction, albeit with low certainty. In contrast, compared to Roux-en-Y reconstruction, uncut Roux-en-Y may increase bile reflux incidence, based on very low-certainty evidence. To strengthen the evidence base, further rigorous and long-term trials are needed. Additionally, these studies should explore variations in surgical procedures, particularly regarding uncut devices and methods to prevent recanalisation. Future research may potentially alter the conclusions of this review.

Meta-analysis of Long-term De Novo Acid Reflux-Related Outcomes Following Sleeve Gastrectomy: Evidence Against the Need for Routine Postoperative Endoscopic Surveillance.

OBJECTIVES: To evaluate the incidence of long-term de novo acid reflux-related complications following sleeve gastrectomy (SG) to determine whether routine postoperative surveillance endoscopy is necessary. METHODS: A systematic search of Medline, Embase, CINAHL, CENTRAL, the Web of Science, and bibliographic reference lists was conducted. A proportion meta-analysis model was constructed to quantify the risk of the de novo gastro-oesophageal reflux disease (GORD), oesophagitis, and Barrett's oesophagus (BE) at least 4 years after SG. Random-effects modelling was applied to calculate pooled outcome data. RESULTS: Thirty-two observational studies were included reporting a total of 7904 patients who underwent primary SG and were followed up for at least 4 years. The median follow-up period was 60 months (48-132). Preoperative acid-reflux symptoms existed in 19.1% ± 15.1% of the patients. The risk of development of de novo GORD, oesophagitis, and BE after SG was 24.8% (95% CI 18.6-31.0%), 27.9% (95% CI 17.7-38.1%), and 6.7% (95% CI 3.7-9.7%), respectively. The between-study heterogeneity was significant in all outcome syntheses. It was suspected that several of the included studies have not reported BE and oesophagitis because such events might not have happened in their cohorts. CONCLUSIONS: Long-term risk of de novo GORD after SG seems to be comparable with those of the general population which questions the merit of surveillance endoscopy after SG in asymptomatic patients. De novo BE and oesophagitis after SG have not been reported by most of the available studies which may lead to overestimation of the rates of both outcomes in any evidence synthesis. We recommend endoscopic surveillance for symptomatic patients only.

Pepsin in saliva for the diagnosis of erosive esophagitis post-sleeve gastrectomy: a prospective observational study.

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) has become the preferred bariatric procedure in many countries. However, new onset erosive esophagitis (EE) is a major shortcoming. Current recommendation is esophago-gastro-duodenoscopy (EGD) should be performed routinely at 1 year and subsequently every 2-3 years to enable the early detection of Barrett's or esophageal adenocarcinoma. This would put significant strains on resources and costs of bariatric program. Our study assesses the association between and diagnostic value of salivary pepsin concentration and endoscopically proven EE in post-LSG patients as a surrogate for EGD. METHODS: Twenty patients on routine post-LSG endoscopy between June and September 2022 were recruited for this correlational pilot study. Under supervision, fasting and post-prandial saliva sample was collected and analyzed by Peptest lateral flow device. EGD examinations were performed, and patients completed a validated 25-item QoLRAD questionnaire. RESULTS: We found a significant correlation between positive endoscopy findings of EE and salivary pepsin concentrations. The normal group had a lower mean fasting pepsin level (13.13 ng/mL ± 18.97) versus the EE-group (90.55 ng/mL ± 81.28, p = 0.009) and lower mean post-prandial pepsin level (30.50 ng/mL ± 57.72) versus the EE-group (135.09 ng/mL ± 130.17, p = 0.02). The predictive probabilities from the binary regression of fasting and post-prandial pepsin concentrations yield AUC of 0.955 ± 0.044 (95% CI 0.868 to 1.000, p < 0.001). CONCLUSION: Our study distinctively identified salivary pepsin to have excellent sensitivity and negative predictive value in EE, potentially useful to preclude the need for post-LSG EGD in asymptomatic patients with low salivary pepsin.

Laparoscopic Nissen Versus Toupet Fundoplication for Short- and Long-Term Treatment of Gastroesophageal Reflux Disease: A Meta-Analysis and Systematic Review.

BACKGROUND: Laparoscopic Nissen fundoplication (LNF) is the most common standard technique worldwidely for Gastroesophageal reflux disease (GERD). Another type of fundoplication, laparoscopic Toupet fundoplication (LTF), intends to reduce incidence of postoperative complications. A systematic review and meta-analysis are required on short- and long-term outcomes based on randomized controlled trials (RCTs) between LNF and LTF. METHODS: We searched databases including PubMed, Cochrane, Embase, and Web of Knowledge for RCTs comparing LNF and LTF. Outcomes included postoperative reflux recurrence, postoperative heartburn, dysphagia and postoperative chest pain, inability to belch, gas bloating, satisfaction with intervention, postoperative esophagitis, postoperative DeMeester scores, operating time (min), in-hospital complications, postoperative use of proton pump inhibitors, reoperation rate, postoperative lower oesophageal sphincter (LOS) pressure (mmHg). We assessed data using risk ratios and weighted mean differences in meta-analyses. RESULTS: Eight eligible RCTs comparing LNF (n = 605) and LTF (n = 607) were identified. There were no significant differences between the LNF and LTF in terms of postoperative reflux recurrence, postoperative heartburn, postoperative chest pain, satisfaction with intervention, reoperation rate in short and long term, in-hospital complications, esophagitis in short term, and gas bloating, postoperative DeMeester scores, postoperative use of proton pump inhibitors, reoperation rate in long term. LTF had lower LOS pressure (mmHg), fewer postoperative dysphagia and inability to belch in short and long term and gas bloating in short term compared to LNF. CONCLUSION: LTF were equally effective at controlling reflux symptoms and improving the quality of life, but with lower rate of complications compared to LNF. We concluded that LTF surgical treatment was superior for over 16 years old patients with typical symptoms of GERD and without upper abdominal surgical history upon high-level evidence of evidence-based medicine.

Transoral incisionless fundoplication for recurrent symptoms after laparoscopic fundoplication.

BACKGROUND: Revision of a failed laparoscopic fundoplication carries higher risk of complication and lower chance of success compared to the original surgery. Transoral incisionless fundoplication (TIF) may be an endoscopic alternative for select GERD patients without need of a moderate/large hiatal hernia repair. The aim of this study was to assess feasibility, efficacy, and safety of TIF 2.0 after failed laparoscopic Nissen or Toupet fundoplication (TIFFF). METHODS: This is a multicenter retrospective cohort study of patients who underwent TIFFF between September 2017 and December 2020 using TIF 2.0 technique (EsophyX Z/Z+) performed by gastroenterologists and surgeons. Patients were included if they had (1) recurrent GERD symptoms, (2) pathologic reflux based upon pH testing or Grade C/D esophagitis or Barrett's esophagus, and (3) hiatal hernia ≤ 2 cm. The primary outcome was improvement in GERD Health-Related Quality of Life (GERD-HRQL) post-TIFFF. The TIFFF cohort was also compared to a similar surgical re-operative cohort using propensity score matching. RESULTS: Twenty patients underwent TIFFF (median 4.1 years after prior fundoplication) and mean GERD-HRQL score improved from 24.3 ± 22.9 to 14.75 ± 21.6 (p = 0.014); mean Reflux Severity Index (RSI) score improved from 14.1 ± 14.6 to 9.1 ± 8.0 (p = 0.046) with 8/10 (80%) of patients with normal RSI (< 13) post-TIF. Esophagitis healed in 78% of patients. PPI use decreased from 85 to 55% with 8/20 (45%) patients off of PPI. Importantly, mean acid exposure time decreased from 12% ± 17.8 to 0.8% ± 1.1 (p = 0.028) with 9/9 (100%) of patients with normalized pH post-TIF. There were no statistically significant differences in clinical efficacy outcomes between TIFFF and surgical revision, but TIFFF had significantly fewer late adverse events. CONCLUSION: Endoscopic rescue with TIF is a safe and efficacious alternative to redo laparoscopic surgery in symptomatic patients with appropriate anatomy and objective evidence of persistent or recurrent reflux.

Incidence of Abnormalities of the Gastric Tube Following Sleeve Gastrectomy and Its Role on Esophagitis Progression.

PURPOSE: The purpose of this study is to determine the incidence of gastric tube abnormalities after SG and its relationship with esophagitis progression. METHODS: Retrospective study which included 459 patients in the postoperative period of SG who underwent an esophagogastroduodenoscopy in both pre- and postoperative periods. The main studied variables were presence of gastric tube abnormalities (dilation, neofundus, twist, and hiatal hernia) and esophagitis progression. RESULTS: Among the 459 patients who underwent SG, 393 (85.6%) were women, and 66 (14.4%) men, with mean age of 40.4 years. Mean preoperative BMI was 39.70 kg/m2. In total, 20.3% of the sample presented progression of esophagitis after surgery. Among the whole sample, 130 (28.3%) presented with an abnormality of the remnant gastric tube. The most common alteration was gastric dilation, which occurred in 16.1% of the patients, followed by gastric twist (10.7%), neofundus (7.4%), and hiatal hernia (0.2%). Patients who presented with any abnormality of the gastric tube were significantly prone to presenting esophagitis progression (p = 0.013). When analyzing each morphological abnormality isolated, there was no statistically significant correlation. CONCLUSION: Abnormalities of the gastric tube are not uncommon after SG and seems to contribute partially to the relevant rates of GERD and esophagitis after this surgery.

Association between the body mass index, waist circumference, and body fat percentage with erosive esophagitis in adults with obesity after sleeve gastrectomy.

Background: High anthropometric indexes before sleeve gastrectomy (SG) are associated with an increased risk of erosive esophagitis (EE) in bariatric surgery candidates. Reasons that explain how these indexes influence the development of esophageal pathology after surgery remains unclear. Objectives: To assess the association between the body mass index (BMI), waist circumference (WC), and body fat percentage (BFP) with the development of EE in adults with obesity three months after SG. Setting: Clínica Avendaño, Lima, Peru. Methods: Retrospective cohort using a database including adults with obesity who underwent SG during 2017-2020. All the patients included had an endoscopy before and after the surgery. Sociodemographic, clinical and laboratory characteristics were compared according to BMI, WC and BFP, as well as by the development of de novo esophagitis. The association was evaluated by crude and adjusted generalized linear models with the log-Poisson family. Results: From a total of 106 patients, 23 (21.7%) developed EE. We did not find significant differences in sociodemographic, clinical and laboratory characteristics between patients with de novo EE compared to those who did not develop EE. After adjustment, BMI (aRR = 0.59, 95% CI = 0.18-1.40), BFP (aRR = 0.41, 95% CI = 0.15-1.19) and WC (aRR = 0.91, 95% CI = 0.69-1.16) were not associated with the development of EE three months post SG. Conclusions: We found no association between preoperative anthropometric indexes and the development of de novo EE; therefore, morbid obesity should not be a criterion to exclude the patients to undergo SG as primary surgery because of the risk of developing EE.

Factors Associated with Increased Severity of Erosive Esophagitis 1 Year After Laparoscopic Sleeve Gastrectomy.

PURPOSE: Weight reduction decreases gastroesophageal reflux disease (GERD), but laparoscopic sleeve gastrectomy (LSG) that damages the structure of the stomach may worsen GERD. We aimed to elucidate the factors associated with increased severity of erosive esophagitis (EE) at 1 year after LSG. MATERIALS AND METHODS: Data on patients who underwent LSG between February 2007 and March 2016 were reviewed. Endoscopic findings and anthropometric data before and after surgery were recorded. The severity of EE was assessed according to the Los Angeles classification; severe EE was defined as grade C or D esophagitis. RESULTS: Totally, 316 patients were enrolled. Before LSG, 96 patients (30.4%) had grade A or B EE. One year after LSG, 215 patients (68%) had EE, including 136 (43%) with grade A, 62 (19.6%) with grade B, and 17 (5.4%) with grade C or D EE. One-hundred and twenty-seven of 220 patients (57.7%) without EE before LSG developed de novo EE following LSG. The incidence of severe EE after LSG in patients without pre-operative EE, grade A EE, or grade B EE at baseline was 3.2%, 6.8%, and 50%, respectively. Independent factors for an increased severity of EE after LSG were male gender (OR = 2.55, 95% CI = 1.52-4.28) and post-operative hiatal hernia (OR = 3.17, 95% CI = 1.66-6.06). CONCLUSION: The prevalence and severity of EE increased after LSG. Male gender and post-operative hiatal hernia are independent factors for an increased severity of EE after LSG. The incidence of severe EE after LSG is low for patients without pre-operative EE or grade A EE at baseline.

Fifteen Years after Sleeve Gastrectomy: Gastroscopies, Manometries, and 24-h pH-Metries in a Long-Term Follow-Up: A Multicenter Study.

INTRODUCTION: Sleeve gastrectomy (SG) is the most common bariatric operation with over 340,000 procedures per year. There are only few studies presenting follow-up results >10 years in the literature today. The aim of this study was the objective evaluation of long-term outcomes of at least 15 years after SG in non-converted patients. METHODS: This study (multicenter cross-sectional; university-hospital based) includes all non-converted patients with primary SG before December 2005 at participating bariatric centers. The following methods were used: gastroscopy, esophageal manometry, 24-h pH-metry, and Gastrointestinal Quality of Life Index (GIQLI). RESULTS: After removing converted patients, patients with bariatric procedures before SG, and deceased patients from the cohort, 20 of 53 participants have met the inclusion criteria. Of this group, 55% are suffering from symptomatic gastroesophageal reflux disease (GERD); 45% are without GERD. Esophagitis, hiatal hernias, Barrett's esophagus, and enlarged sleeves were found in 44%, 50%, 13%, and 69% of patients during gastroscopy. Mean lower esophageal sphincter pressure was normal at 20.2 ± 14.1 mm Hg during manometry. Reflux activity in 24 h, number of refluxes, and DeMeester score were increased at 12.9 ± 9.7%, 98.0 ± 80.8, and 55.3 ± 36.3 during 24-h pH-metry. Patients with GERD scored significantly lower in the GIQLI than patients without GERD: 107.6 ± 18.4 versus 127.6 ± 14.4 (p = 0.04). DISCUSSION/CONCLUSION: Fifteen years after primary SG, objective testing has shown that GERD, esophagitis, and Barrett's esophagus are major issues for these patients. Surveillance endoscopies at 5-year intervals in all SG patients and 3-year intervals in patients with Barrett's esophagus are recommended.

Clinical Endoscopic and Histologic Findings of a Long-Term Follow-Up (10.7 Years) After Roux-en-Y Laparoscopic Gastric Bypass: a Prospective Study.

INTRODUCTION: Bariatric surgery, with laparoscopic Roux-en-Y gastric bypass (LYGB), is one of the most effective treatments for long-term weight loss. However, there are few publications concerning endoscopic evaluations at late control. The purpose was to evaluate the macroscopic and histological findings at the distal esophagus, gastric pouch, jejunal limb and the evolution of Barrett's esophagus (BE) in the long term. METHODS: Cohort of 110 patients with obesity underwent LYGB in a university hospital. Several clinical, endoscopic and histological evaluations were performed after surgery. Exclusion criteria were previous bariatric procedure, hiatal hernia > 4 cm, BE with histological dysplasia and body mass index (BMI) > 50 kg/m2. RESULTS: Average age was 38.7 ± 9 years with 70% females. BMI averaged 39.6 ± 6 kg/m2. Follow-up was 10.7 ± 2 years, and 18 patients (16.4%) were lost. The total weight loss was 23.4 ± 7 kg. Erosive esophagitis, present in 33% of patients, decreased to 5%. After surgery, intestinal metaplasia regressed to cardial mucosa in 5 of 8 patients. One patient developed a short-segment BE. The level of control to gastroesophageal reflux disease (GERD) symptom control was 87% to responders (Visick I-II) and 13% to non-responders (Visick III-IV). An increase in dilated cardia type III was observed (p < 0.001). The length of the gastric pouch increased significantly after surgery (p < 0.001). Anastomotic ulcers healed at 6 months with proton pump inhibitor (PPI) use, without recurrence. CONCLUSION: LYGB is a very effective surgical procedure to control symptoms of GERD and/or endoscopic erosive esophagitis. Besides, regression of Barrett's mucosa to carditis occurred in 62%.

Laparoscopic sleeve gastrectomy with Rossetti fundoplication: long-term (5-year) follow-up.

BACKGROUND: Gastroesophageal reflux disease (GERD), including erosive esophagitis, is highly prevalent in the obese population. Barrett's esophagus is the consequence of untreated GERD. Laparoscopic sleeve gastrectomy is one of the most frequently performed bariatric procedures. This study presents results after 5 years of follow-up of combined LSG and Rossetti fundoplication for the treatment of GERD, esophagitis, and Barrett's esophagus in patients with morbid obesity. OBJECTIVE: To evaluate long-term results after sleeve gastrectomy with Rossetti fundoplication. SETTING: Public university hospital in Italy. METHODS: Since January 2015, more than 450 patients with obesity underwent sleeve gastrectomy with a Rossetti fundoplication procedure as part of prospective studies underway at our center performed by 4 different expert bariatric surgeons. Currently, 127 patients have a follow-up of 5 years or more. RESULTS: Mean patient age was 42.9 ± 10.3 years, and mean body mass index was 42.4 ± 6.1 kg/m2. In total, 74.8% of patients were experiencing GERD before surgery. In 29 of 127 patients (22.8%), preoperative gastroscopy showed signs of esophagitis and/or Barrett's esophagus. In particular, 23 of 127 patients (18.1%) had grade A esophagitis, 2 of 127 (1.6%) had grade B, 2 of 127 (1.6%) had grade C, and 2 of 127 (1.6%) had Barrett's esophagus. Mean operative time was 51 ± 21 minutes. No intraoperative complications or conversions were reported. A regular postoperative course was seen in 91.3% of patients. Sixty months after surgery, more than 95% of patients did not experience any reflux symptoms. Percent total weight loss at follow-up was comparable with that with sleeve gastrectomy. Endoscopic follow-up demonstrated improvement of esophagitis lesions (including Barrett's esophagus) present in the preoperative setting. CONCLUSION: Laparoscopic sleeve gastrectomy with Rossetti fundoplication is well tolerated, feasible, and safe in patients with obesity, providing adequate weight loss results and complete resolution of clinical signs of GERD. We have recorded an improvement in esophagitis lesions present at preoperative gastroscopy and complete resolution of Barrett's esophagus within 5 years of follow-up.

Effect of Laparoscopic Sleeve Gastrectomy vs Roux-en-Y Gastric Bypass on Weight Loss, Comorbidities, and Reflux at 10 Years in Adult Patients With Obesity: The SLEEVEPASS Randomized Clinical Trial.

Importance: Long-term results from randomized clinical trials comparing laparoscopic sleeve gastrectomy (LSG) with laparoscopic Roux-en-Y-gastric bypass (LRYGB) are limited. Objective: To compare long-term outcomes of weight loss and remission of obesity-related comorbidities and the prevalence of gastroesophageal reflux symptoms (GERD), endoscopic esophagitis, and Barrett esophagus (BE) after LSG and LRYGB at 10 years. Design, Setting, and Participants: This 10-year observational follow-up evaluated patients in the Sleeve vs Bypass (SLEEVEPASS) multicenter equivalence randomized clinical trial comparing LSG and LRYGB in the treatment of severe obesity in which 240 patients aged 18 to 60 years with median body mass index of 44.6 were randomized to LSG (n = 121) or LRYGB (n = 119). The initial trial was conducted from April 2008 to June 2010 in Finland, with last follow-up on January 27, 2021. Interventions: LSG or LRYGB. Main Outcomes and Measures: The primary end point was 5-year percentage excess weight loss (%EWL). This current analysis focused on 10-year outcomes with special reference to reflux and BE. Results: At 10 years, of 240 randomized patients (121 randomized to LSG and 119 to LRYGB; 167 women [69.6%]; mean [SD] age, 48.4 [9.4] years; mean [SD] baseline BMI, 45.9 [6.0]), 2 never underwent surgery and there were 10 unrelated deaths; 193 of the remaining 228 patients (85%) completed follow-up on weight loss and comorbidities, and 176 of 228 (77%) underwent gastroscopy. Median (range) %EWL was 43.5% (2.1%-109.2%) after LSG and 50.7% (1.7%-111.7%) after LRYGB. Mean estimate %EWL was not equivalent between the procedures; %EWL was 8.4 (95% CI, 3.1-13.6) higher in LRYGB. After LSG and LRYGB, there was no statistically significant difference in type 2 diabetes remission (26% and 33%, respectively; P = .63), dyslipidemia (19% and 35%, respectively; P = .23), or obstructive sleep apnea (16% and 31%, respectively; P = .30). Hypertension remission was superior after LRYGB (8% vs 24%; P = .04). Esophagitis was more prevalent after LSG (31% vs 7%; P < .001) with no statistically significant difference in BE (4% vs 4%; P = .29). The overall reoperation rate was 15.7% for LSG and 18.5% for LRYGB (P = .57). Conclusions and Relevance: At 10 years, %EWL was greater after LRYGB and the procedures were not equivalent for weight loss, but both LSG and LRYGB resulted in good and sustainable weight loss. Esophagitis was more prevalent after LSG, but the cumulative incidence of BE was markedly lower than in previous trials and similar after both procedures.

Esophagogastric complications in radiofrequency and cryoballoon catheter ablation of atrial fibrillation.

INTRODUCTION: Direct comparison studies about the incidence of esophagogastric complications between radiofrequency (RF) and cryoballoon (CB) catheter ablation (CA) for atrial fibrillation (AF) have been scarce. We sought to elucidate the relationship between the pulmonary vein isolation (PVI) modalities and esophagogastric complications. METHODS: The study population consisted of 254 patients who underwent CA for AF from November 2017 to October 2018. Finally, 160 patients were enrolled and divided into the RF and CB groups. Esophageal ulcers, gastric hypomotility, and exfoliative esophagitis detected by esophagogastroduodenoscopy were defined as esophagogastric complications in this study. RESULTS: The median age was 68 years old, with 34% being females. Esophagogastric complications were observed in 42.5% of patients who underwent CA. According to the detailed esophagogastric complications, the RF group had a higher prevalence of esophageal ulcers than the CB group (19% vs. 0%, p < .0001). There was no significant difference between the two groups regarding gastric hypomotility and exfoliative esophagitis (18% vs. 28%; p = .15 and 16% vs. 21%; p = .42, respectively). CONCLUSION: Asymptomatic esophagogastric complications were common in CA for AF. The incidence of esophageal ulcers was higher in the RF group than in the CB group, whereas the other esophagogastric complications did not significantly differ.

Gastroesophageal Reflux Disease, Esophagitis, and Barrett's Esophagus 3 to 4 Years Post Sleeve Gastrectomy.

BACKGROUND: Sleeve gastrectomy (SG) has become the most popular bariatric procedure worldwide. However, SG is associated with de novo gastroesophageal reflux (GERD) and esophagitis, with concerns for progression into Barrett's esophagus (BE). The purpose of this study is to assess the clinical and endoscopic progression of GERD, esophagitis, and BE 3 to 4 years after SG. METHODS: Fifty-eight patients (pts) were assessed with endoscopy preoperative and at 3 to 4 years post SG, representing 44.9% follow-up. Endoscopy was offered to all SG pts regardless of symptoms. Outcomes including percent total weight loss (%TWL), PPI use, esophagitis progression, de novo reflux, and BE formation. RESULTS: At post-op follow-up, the %TWL was 23%. The average BMI dropped from 49.07 to 37.5. De novo reflux developed in 13 pts (30.9%). Of the 16 pts with GERD pre-op, 37.5% improved, 25% had stable disease, and 37.5% had worsening symptoms. The rate of esophagitis nearly doubled from 37.9% pre-op to 70.6% post-op. A majority of post-op pts had mild esophagitis (87.8%), with 12.1% with LA classes C and D. Asymptomatic esophagitis was found in 68.2% of post-op pts. The incidence of BE was 12.7% post-op, with de novo BE developing in 4 pts, representing 7.2%. CONCLUSION: SG is associated with increased rates of asymptomatic esophagitis and de novo reflux at 3 to 4 years post-op. De novo BE was detected as well, highlighting the importance of post-op screening. The majority of pts with GERD pre-op have stable disease or improve.

Resolution of Erosive Esophagitis After Conversion from Vertical Sleeve Gastrectomy to Roux-en-Y Gastric Bypass.

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) has become the preferred bariatric procedure in many countries. However, there is one shortcoming of LSG in the long-term follow-up, and this is the onset of gastro-esophageal reflux disease (GERD) and erosive esophagitis (EE). Conversion to Roux-en-Y gastric bypass (RYGB) is considered an option in patients unresponsive to medical therapy. Currently, there is no evidence of EE improvement or resolution after conversion surgery. In this study, we objectively evaluate the effectiveness of RYGB in management of EE with upper endoscopy (EGD) to identify the significant variables in patients with GERD symptoms post LSG refractory to medical therapy and require conversion surgery. METHODS: Over a period of 11 years (2008-2019) at Singapore General Hospital, we retrospectively reviewed a prospectively collected database of a cohort of patients whom had conversion surgery to RYGB for refractory GERD and EE after LSG. Patient's endoscopic findings and demographic and anthropometric data were analyzed. RESULTS: We identified a total of 14 patients who underwent LSG to RYGB conversions for endoscopic proven erosive esophagitis in our unit during the study period. Eight patients (57.1%) had concurrent hiatal hernia repaired. Nine (64.3%) patients were females. The median age of patients in this cohort was 44 (range 30-61) years. Mean weight and BMI were 87.7 kg (± 19.2) and 32.8 (± 3.09) kg/m2, respectively, on the day of conversion surgery. The median time between LSG and revision to RYGB was 36 (range 6-68) months. Seven patients (50%) had complete resolution of GERD symptoms after conversion, and 6 patients (42.9%) had partial resolution. Six out of 7 patients had complete resolution of EE. There were 4 anastomotic strictures (28.6%). Older patients, Indian ethnicity, present of hiatal hernia and lower weight loss after initial LSG were more likely to undergo conversion surgery. CONCLUSION: Conversion to RYGB after LSG is clinically relevant and may be a feasible solution if patients have ongoing GERD refractory to medical therapy. Ninety-three percent of our patients achieved complete resolution of their GERD symptoms and significant improvement of erosive esophagitis with significant weight loss after conversion. This study has important implications as LSG is increasingly being performed and a proportion of these will need revision surgery for various reasons, particularly GERD which is extremely prevalent.

A Creeping Malaise Leading to Calamity: Herpes Esophagitis Perforation.

Herpes simplex virus is an uncommon cause of esophagitis and particularly so in immunocompetent individuals. Although the common presentation tends to be odynophagia and/or dysphagia, fever, and retrosternal chest pain, there are variations and rarely it can present more ominously as esophageal rupture. We report a rare case of esophageal perforation with penetration into the vertebral space secondary to chronic herpes simplex virus esophagitis in a 71-year-old immunocompetent woman. This is the second known such occurrence. The patient had a long stay in the hospital but recovered from the condition and was followed up for 1 year after initial presentation.

Bile Reflux is a Common Finding in the Gastric Pouch After One Anastomosis Gastric Bypass.

INTRODUCTION: Data on postoperative bile reflux after one anastomosis gastric bypass (OAGB) is lacking. Bile reflux scintigraphy (BRS) has been shown to be a reliable non-invasive tool to assess bile reflux after OAGB. We set out to study bile reflux after OAGB with BRS and endoscopy in a prospective series (RYSA Trial). METHODS: Forty patients (29 women) underwent OAGB between November 2016 and December 2018. Symptoms were reported and upper gastrointestinal endoscopy (UGE) was done preoperatively. Six months after OAGB, bile reflux was assessed in UGE findings and as tracer activity found in gastric tube and esophagus in BRS (follow-up rate 95%). RESULTS: Twenty-six patients (68.4%) had no bile reflux in BRS. Twelve patients (31.6%) had bile reflux in the gastric pouch in BRS and one of them (2.6%) had bile reflux also in the esophagus 6 months postoperatively. Mean bile reflux activity in the gastric pouch was 5.2% (1-21%) of total activity. De novo findings suggestive of bile reflux (esophagitis, stomal ulcer, foveolar inflammation of gastric pouch) were found for 15 patients (39.5%) in postoperative UGE. BRS and UGE findings were significantly associated (P = 0.022). Eight patients experienced de novo reflux symptoms at 6 months, that were significantly associated with BRS and de novo UGE findings postoperatively (P = 0.033 and 0.0005, respectively). CONCLUSION: Postoperative bile reflux in the gastric pouch after OAGB is a common finding in scintigraphy and endoscopy. The long-term effects of bile exposure will be analyzed in future reports after a longer follow-up. TRIAL REGISTRATION: Clinical Trials Identifier NCT02882685.
