Abstract
Importance Metabolic bariatric surgery is the most effective and durable treatment for weight loss and improvement of cardiovascular diseases. With sleeve gastrectomy now surpassing gastric bypass as the most common procedure worldwide, comparing these procedures' associations with major adverse cardiac events (MACE) is needed. Objective To compare the risk of MACE among individuals undergoing gastric bypass or sleeve gastrectomy. Design, Setting, and Participants This population-based, inverse probability-weighted cohort study was conducted using administrative claims data from Switzerland among adults undergoing gastric bypass or sleeve gastrectomy for obesity treatment between January 2012 and December 2022. Inpatient individuals with a primary or secondary discharge procedure code for gastric bypass or sleeve gastrectomy were eligible for inclusion. Data were analyzed from April 2024 to September 2025. Exposure Gastric bypass vs sleeve gastrectomy. Main Outcomes and Measures A weighted cohort was analyzed to study the primary outcome of 4-point MACE, including acute myocardial infarction, ischemic stroke, hospitalizations for heart failure, and all-cause mortality. Secondary outcomes were the individual components of MACE, surgical reinterventions, and associated complications. Results Of 39 067 patients, 30 270 patients (77.5%) underwent gastric bypass and 8798 patients (22.5%) underwent sleeve gastrectomy. Median (IQR) patient age was 42 (35-50) years, and 28 560 patients (73.1%) were women. A total of 23 708 patients (60.7%) had a body mass index (calculated as weight in kilograms divided by height in meters squared) of 40 or higher. After weighting, over a median (IQR) follow-up of 5.1 years (2.6-7.6), the primary outcome occurred in 577 patients in the gastric bypass group (1.9%) and 264 patients in the sleeve gastrectomy group (3.0%), with incidence rates of 3.96 and 5.10 per 1000 patient-years, respectively (hazard ratio [HR], 0.75; 95% CI, 0.64-0.88). This difference was primarily driven by lower rates of acute myocardial infarction (HR, 0.63; 95% CI, 0.46-0.86). No differences were observed in ischemic stroke, hospitalization for heart failure, and all-cause mortality. Both short- and long-term secondary outcomes favored gastric bypass over sleeve gastrectomy, except for higher rates of revision surgery and immediate postoperative complications. Conclusions and relevance In this inverse probability-weighted cohort study, for patients undergoing metabolic bariatric surgery, gastric bypass was associated with lower rates of MACE than sleeve gastrectomy over a follow-up period of up to 11 years. Known postoperative complications were confirmed for both gastric bypass and sleeve gastrectomy.

Abstract
BACKGROUND Bariatric surgery has been shown to cause a negative impact on oral health, as reflected by postsurgical increase of caries-related dental interventions. OBJECTIVES The aim of this study was to compare dental intervention rates after Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG). SETTING Nationwide and register-based (Sweden). METHODS This 2-staged matched cohort study included all adults who underwent RYGB (n = 26,594) or SG (n = 3416) between 2011 and 2015, registered in the Scandinavian Obesity Surgery Register. Propensity score matching was used to match SG patients to RYGB patients, based on several covariates. The follow-up time was 3 years after surgery. The dental variables were collected from the Dental Health Register, including tooth extractions, restorative interventions (dental fillings), and endodontic interventions (root canal treatment). RESULTS In total, 3317 RYGB and 3317 SG patients were included. Both groups showed increased dental event rates postoperatively. RYGB patients had significantly higher event rates compared with SG postoperatively regarding all interventions, restorative and endodontic interventions. CONCLUSIONS The negative effect on dental outcomes in terms of dental fillings and tooth extractions were higher after RYGB than after SG. The reasons are not clear. More research is needed to replicate these findings, to understand the mechanisms, and further delineate the significance of the surgical method.

Outcomes of Concomitant Laparoscopic Sleeve Gastrectomy and Hiatal Hernia Repair on Gastroesophageal Reflux Disease in Patients with Severe Obesity: A Propensity Score-Matched Analysis. Obes Surg 2025; 35:1685-1692. [PMID: 40205116 DOI: 10.1007/s11695-025-07815-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2024] [Revised: 02/05/2025] [Accepted: 03/17/2025] [Indexed: 04/11/2025]
Abstract
BACKGROUND Hiatal hernia (HH) is frequent in patients with obesity who have undergone bariatric surgery, but there is controversy about HH repair (HHR) during bariatric surgery. This study aimed to analyze the safety and efficacy of concomitant laparoscopic sleeve gastrectomy (LSG) and HHR in patients with severe obesity. METHODS A propensity score-matched analysis was conducted for patients who underwent LSG. Preoperative barium meal, upper endoscopy, and intraoperative findings were used to diagnose HH. The GERD health-related quality of life (GERD-HRQL) questionnaire was used to diagnose gastroesophageal reflux disease (GERD). Patients were divided into two groups: one underwent concomitant LSG with HHR and the other underwent LSG only. HHR was performed by cruroplasty and reconstruction of the phrenoesophageal ligament (PEL). Gastropexy was performed by fixing the gastric tube to the omentum and peripancreatic fascia. Outcomes included blood loss, operative time, postoperative complications, GERD, and percent excess weight loss. RESULTS Of the 406 patients included in the study, 203 patients with HH underwent LSG with HHR, while 203 underwent LSG alone. There was significantly longer operative time in the LSG with HHR group, but no statistical difference between the groups regarding postoperative complications, except postoperative GERD. De novo GERD symptoms developed significantly in the LSG only group. These results indicate that concomitant LSG with HHR leads to improvement of GERD and decreases the rate of de novo GERD symptoms. CONCLUSIONS HH should be repaired by cruroplasty and reconstruction of the PEM during LSG. HHR helps to improve postoperative GERD symptoms.

Gastroesophageal Reflux and Gastrointestinal Symptoms After Metabolic and Bariatric Surgery in Adolescents: An 8-year Follow-up Analysis. J Pediatr Surg 2025; 60:162215. [PMID: 39933471 DOI: 10.1016/j.jpedsurg.2025.162215] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/09/2024] [Revised: 01/23/2025] [Accepted: 01/24/2025] [Indexed: 02/13/2025]
Abstract
IMPORTANCE Vertical sleeve gastrectomy (VSG) and Roux-en-Y gastric bypass (RYGB) are the most commonly performed metabolic and bariatric surgery (MBS) procedures in adolescents and adults. Despite their safety and effectiveness, there is concern over postoperative gastrointestinal symptoms (GIS), especially gastroesophageal reflux symptoms (GERS), in those undergoing VSG. OBJECTIVE To evaluate the long-term prevalence of GIS in adolescents who underwent RYGB or VSG. DESIGN, SETTING, AND PARTICIPANTS This is a prospective, multicenter, observational cohort study at five academic referral centers in the United States. Patients were enrolled from February 28, 2007, through December 30, 2011. The analysis included 228 adolescents: 161 RYGB and 67 VSG followed prospectively for 8 years. MAIN OUTCOMES AND MEASURES Patient-reported GIS before surgery and across 8 years of postoperative follow-up were assessed. We dichotomized postoperative symptom severity and analyzed the data using general linear mixed models. RESULTS Adolescents undergoing either VSG or RYGB demonstrated significant increases in abdominal pain (10 % vs. 17 %), bloating (8 % vs. 20 %), and constipation (3 % vs. 9 %) between baseline and 8 years (p < 0.05). Following RYGB, the prevalence of GERS was not statistically significantly different between baseline (12 %) and 8 years (13 %) (p > 0.05). Following VSG, however, GERS increased from 9 % preoperatively to 27 % at 8 years (p < 0.05). In adjusted analyses, VSG was associated with higher odds of GERS at 8 years (adjusted odds ratio 2.67 [1.57-4.55, 95%CI]). CONCLUSIONS AND RELEVANCE GERS represents a considerable concern pre- and post-MBS in adolescents, especially after VSG. Appropriate patient selection along with counseling and objective monitoring for pathologic consequences of gastroesophageal reflux after MBS are warranted. TRIAL REGISTRATION Clinicaltrials. gov Identifier: NCT00474318. TYPE OF STUDY Prospective, multicenter, observational cohort. LEVEL OF EVIDENCE Level II.

Abstract
PURPOSE Metabolic syndrome (MetS) plays a key role in the progression of esophageal cancer (EC), yet few studies have comprehensively explored research trends on this topic. To fill this gap, this study analyzes global research developments, hotspots, and collaborations related to MetS and EC. METHODS A total of 1008 publications from 1995 to 2024 were analyzed using bibliometric tools like VOSviewer, CiteSpace, and the R package 'bibliometrix', drawing from the Web of Science Core Collection. RESULTS The analysis includes contributions from 5,183 researchers at 1500 institutions across 85 countries, with publications appearing in 411 journals. The United States, China, and the United Kingdom are leading in both publication volume and research impact. Karolinska Institutet emerged as a prominent contributor to this body of work. Key journals include the Diseases of the Esophagus and Gastroenterology. Main areas cover metabolic factors, metabolic surgery, adipokines, lifestyle risk factors, cirrhosis & portal hypertension. Emerging trends focus on "metabolic syndrome and EC risk", "inflammation and adipokines", "bariatric surgery and EC prevention", "post-surgical outcomes", "early detection strategies". CONCLUSION As the first comprehensive bibliometric study on MetS and EC, this research highlights metabolism-related factors driving EC progression. Future research should focus on clarifying MetS-EC mechanisms and developing prevention and treatment strategies.

Patients with Severe Obesity Undergoing Roux-En-Y Gastric Bypass Versus Sleeve Gastrectomy: A Systematic Review and an Updated Meta-Analysis. Obes Surg 2025; 35:1146-1159. [PMID: 39964665 DOI: 10.1007/s11695-025-07743-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2024] [Revised: 10/09/2024] [Accepted: 02/07/2025] [Indexed: 03/14/2025]
Abstract
BACKGROUND Laparoscopic Roux-En-Y Gastric Bypass (LRYGB) contributes significantly to higher weight loss at 6 to 12 months when compared to Laparoscopic Sleeve Gastrectomy (LSG) in patients with severe obesity (SO-body mass index (BMI) ≥ 50 kg/m2). However, there is still no consensus regarding the best procedure in terms of mortality and complication rates. We performed a systematic review and meta-analysis to compare the complication rates between these two surgical procedures. METHODS PubMed, EMBASE, and Cochrane Central were searched for studies that compared LRYGB and LSG in SO patients. We pooled outcomes for mortality and complications, defined as bleeding, cardiovascular events, conversion to open procedure, and a composite endpoint of leak, abscess, fistulas, and reoperation. Length of stay and operative time were also pooled. A random-effects model was used, and statistical analyses were performed using R version 4.4.0. RESULTS A total of 156,767 patients from 28 observational studies were included, of whom 79,324 (50.6%) underwent LRYGB and 77,443 (49.4%) LSG. Length of stay (MD 0.45; 95% CI 0.42-0.48; P < 0.01) and operative time (MD 58.88; 95% CI 37.88-79.87; P < 0.01) were lower in the LSG group. Overall, there was no difference in mortality (OR 1.28; 95% CI 0.80-2.04; P = 0.311) and in complication rates (OR 1.22; 95% CI 0.85-1.76; P = 0.287). A subgroup analysis showed lower conversion to open procedure for patients who underwent LSG (OR 2.75; 95% CI 1.90-3.98; P < 0.001), and no difference was noted in bleeding (OR 0.98; 95% CI 0.47-2.07; P = 0.965), cardiovascular events (OR 0.99; 95% CI 0.43-2.29; P = 0.983), and a composite endpoint of leak, abscess, and fistulas (OR 0.82; 95% CI 0.67-1.01; P = 0.066). CONCLUSION Our meta-analysis suggests that there is no difference in mortality and complication rates between the two groups. However, length of stay and operative time were lower in SO patients who underwent LSG.

Abstract
BACKGROUND Symptoms of reflux after sleeve gastrectomy (SG) are common and may be refractory to medical treatment. OBJECTIVES To assess outcomes of conversion of SG to Roux-en-Y gastric bypass (RYGB) with concomitant repair of hiatal hernias on symptoms of reflux. SETTING Tertiary community hospital. METHODS We reviewed data from all consecutive patients (2018-2021) who underwent conversion from SG to RYGB for refractory reflux symptoms. Concomitant hiatal hernias were diagnosed endoscopically or radiographically. Improvement in reflux symptoms, nausea, vomiting, dysphagia, or abdominal pain and postoperative proton pump inhibitor (PPI) use were compared with McNemar statistical test. Data are reported as mean ± standard deviation. RESULTS In total, 64 patients (92% female; 48 ± 10 years) underwent conversion from SG to RYGB and repair of concomitant hiatal hernias 4 ± 3 years after the index SG. A hiatal hernia was detected preoperatively in 57 of 64 patients (89%) by either upper gastrointestinal contrast studies, computed tomography scan, or esophagogastroduodenoscopy. At 29 ± 14 months postconversion to RYGB, percent total body weight loss was 14 ± 9% and percent excess weight loss was 37 ± 29%, and body mass index decreased from 37 ± 7 to 32 ± 6 kg/m2. Symptoms of reflux and use of PPI improved during the early follow-up period (median: 14 months; P < .001) and was sustained at late follow-up (median: 32 months; P < .01). Improvement of nausea and dysphagia reached statistical significance at late follow-up (median: 32 months; P < .01). Vomiting and abdominal pain decreased with time but did not reach statistical significance. Postoperative complications were deep surgical-site infection (n = 3), pulmonary embolism (n = 1), bleeding (n = 5), reoperation (n = 3), and 30-day readmission (n = 6). CONCLUSIONS Conversion of SG to RYGB and repair of concomitant hiatal hernia improves reflux symptoms, nausea, and dysphagia, reduces PPI use, and confers additional weight loss.

Abstract
Background and Objectives: Bariatric surgery is the most effective method for achieving sustainable weight loss, improving quality of life, and resolving obesity-related comorbidities over the long term. However, data from long-term studies remain scarce and contradictory. Materials and Methods: This study is a retrospective analysis of prospectively collected data over a 7-year follow-up period involving 211 patients diagnosed with morbid obesity who underwent sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB), or mini gastric bypass (MGB) at Samsun University Training and Research Hospital, Department of General Surgery, between 1 January 2014 and 1 January 2018. Changes in weight, remission of associated comorbidities, postoperative complications, re-admission rates, and revision requirements were compared among the patients. Results: Of the 211 patients, 20.4% were male, and 79.6% were female. During the study period, 61.1% of patients underwent SG, 29.4% underwent MGB, and 9.5% underwent RYGB. There was no statistically significant difference among the three surgical techniques in terms of weight change parameters, comorbidity remission, postoperative complications, and readmission rates. However, revision rates were significantly higher among patients who underwent SG (p < 0.05). Conclusions: SG, MGB, and RYGB techniques are comparable and reliable methods in terms of long-term weight loss, surgical outcomes, and complications. After a 7-year follow-up period, all three techniques were found to be similar in terms of HT, T2DM, and GERD remission; however, SG was observed to have a higher revision requirement compared to the other surgical techniques.

Abstract
BACKGROUND & AIMS Sleeve gastrectomy (SG) is one of the most commonly performed bariatric procedures worldwide. Gastroesophageal reflux disease (GERD) is a major concern in patients undergoing SG and is a risk factor for Barrett's esophagus (BE). We conducted a systematic review and meta-analysis to assess the incidence of and analyze predictive factors for post-SG BE. METHODS A comprehensive literature search was conducted in April 2024, for studies reporting on incidence of BE, erosive esophagitis (EE), and hiatal hernia (HH) post-SG. Primary outcomes were post-SG pooled rates of de novo BE, EE, GERD symptoms, proton pump inhibitor use, and HH. Meta-regression analysis was performed to assess if patient and post-SG factors influenced the rates of post-SG BE. RESULTS Nineteen studies with 2046 patients (79% females) were included. Mean age was 42.2 years (standard deviation, 11.1) and follow-up ranged from 2 to 11.4 years. The pooled rate of de novo BE post-SG was 5.6% (confidence interval, 3.5-8.8). Significantly higher pooled rates of EE (risk ratio [RR], 3.37], HH (RR, 2.09), GER/GERD symptoms (RR, 3.32), and proton pump inhibitor use (RR, 3.65) were found among patients post-SG. GER/GERD symptoms post-SG positively influenced the pooled BE rates, whereas age, sex, body mass index, post-SG EE, and HH did not. CONCLUSIONS Our analysis shows that SG results in a significantly increased risk of de novo BE and higher rates of EE, proton pump inhibitor use, and HH. Our findings suggest that clinicians should routinely screen patients with SG for BE and future surveillance intervals should be followed as per societal guidelines.

Abstract
Bariatric surgery has evolved and gained in popularity as it has been recognized as the most sustainable and effective treatment for obesity and related diseases. These related diseases are significant causes of obesity related morbidity and mortality. Most bariatric procedures incorporate some component of gastric restriction with or without intestinal bypass, but the full mechanism of these procedures has yet to be elucidated. The most popular surgical procedure remains the sleeve gastrectomy over the last 10 years, while gastric bypass is also still commonly performed. We have also seen growth in revisional bariatric surgery and novel surgical procedures.

Abstract
BACKGROUND The association between bariatric surgery and esophagogastric cancer (EGC) is debated. This study aimed to assess EGC characteristics and surgery outcomes comparing bariatric and non-bariatric patients. METHODS Single-center retrospective analysis of prospective EGC surgery database. RESULTS EGC-surgery was performed in 269 patients, classified as bariatric (N.=10, 3.3%), and non-bariatric (N.=259, 96.6%) groups. Non-bariatric group was sub-classified into body mass index (BMI) <35 kg/m2 (N.=244) and >35 kg/m2 (N.=15). BMI was 35.3±5.6 vs. 25.7±16.1 and 37.8±8.7 kg/m2 in bariatric vs. non-bariatric-BMI <35 and >35, respectively (P<0.001). Bariatric patients were significantly younger (56.75±11 vs. 71±10 and 68.38±8.2 years; P<0.001). They tended to have lower rates of diabetes mellitus (30% vs. 43.9% and 73.3%; P=0.05) and significantly lower hypertension rates (50%, vs.86.5% and 93.3%, P<0.004). Bariatric procedures were performed 11.3 years (IQR 5.5-16.5) prior to EGC-surgery. Tumor characteristics were statistically comparable except a significantly higher number of positive LN in the bariatric group (6.9±13.6 vs. 2.7±4.9 and 1.9±4.8; P=0.006), and more bariatric patients received adjuvant treatment (P=0.035). Postoperative major complication rates (0% vs. 25.8%, and 33.3%; P=0.14) and length of hospital stay (14.1±15.3, vs. 23±28.5, and 21±18 days; P=0.59) were comparable. There was no significant difference in Disease- free survival (P=0.42) or overall survival (P=0.48) between patient-groups. CONCLUSIONS Bariatric patients were diagnosed with EGC at a younger age, and tended to have worse nodal involvement. Although outcomes were comparable, clinical and endoscopic surveillance seem important as EGC can occur 10 years or earlier than in non-bariatric patients.

Abstract
The study aimed to evaluate the mid-term weight loss outcomes and complications of revisional one-anastomosis gastric bypass (OAGB) following failed laparoscopic sleeve gastrectomy (LSG). A total of 586 patients underwent LSG from January 2010 to February 2018. Revisional OAGB (rOAGB) was performed in 22 (3.8%) patients. A retrospective analysis of prospectively collected data from 20 patients with at least 12 months of follow-up after the revisional OAGB was carried out. The indications for revisional surgery were as follows: insufficient weight loss-4 (20%), weight regain-13 (65%), weight regain and symptoms of gastroesophageal reflux disease (GERD)-2 (10%), and dysphagia with gastroesophageal reflux-1 (5%). The mean interval between the LSG and rOAGB was 35.3 ± 15.4 months (range 4-64). The mean follow-up time after rOAGB was 45.5 ± 17.1 months (range 12-54). At the end of the follow-up after rOAGB, %TWL was 26.4 ± 8.9%, and %EWL was 58.5 ± 21.6%, based on pre-LSG body weight. In all three patients with intractable GERD, the clinical symptoms of reflux retreated after revisional OAGB. The overall complication rate was 20%. In conclusion, the main indications for revision after LSG are weight regain, insufficient weight loss, and intractable GERD. Revisional OAGB emerges as a viable surgical alternative for unsuccessful LSG, presenting notable weight loss outcomes; however, it may be linked to an increased incidence of complications.

Abstract
INTRODUCTION Adherence to follow-up (FU) care after bariatric surgery is poor despite strong recommendations. In our pilot Bella trial, we demonstrated that a completely remote follow-up program via smartphone is feasible and safe for patients after bariatric surgery. Building on this, we aim to verify our results in a multicenter, randomized controlled setting. METHODS This trial plans to enroll 410 participants undergoing primary bariatric surgery in seven German bariatric centers. Participants are randomized into two groups: a control group receiving in-person FU according to the standard in the bariatric centers, and an interventional group monitored using a smartphone application (app). The app sends standardized questionnaires and reminders regarding regular vitamin intake and exercises. The built-in messaging function enables patients to communicate remotely with medical care professionals. After one year, all participants are evaluated at their primary bariatric centers. The primary outcome is weight loss 12 months after surgery. The secondary outcomes include obesity-related comorbidities, quality of life, serum values of vitamins and minerals, body impedance analysis, visits to the emergency department or readmission, patient compliance, and medical staff workload. DISCUSSION The current study is the first prospective, individually randomized-controlled, multicenter trial where a mobile application completely replaces traditional in-person visits for post-bariatric surgery follow-ups in bariatric centers.

Abstract
BACKGROUND The field of metabolic and bariatric surgery (MBS) is currently an expanding surgical field with constant refinements in techniques, outcomes, indications, and objectives. MBS has been effectively applied across diverse patient demographics, including varying ages, genders, body mass indexes, and comorbidity statuses. METHODS We performed a comprehensive literature review of published retrospective cohort studies, meta-analyses, systematic reviews, and literature reviews from inception to 2024, reporting outcomes of MBS using databases such as PubMed, ScienceDirect, and Springer Link. RESULTS MBS is a safe and efficient therapeutic option for patients with obesity and associated medical conditions (mortality rate 0.03-0.2%; complication rates 0.4-1%). The favorable safety profile of MBS in the short-, mid-, and long-term offers the potential to treat patients with obesity and type 2 diabetes mellitus, immunosuppression, chronic anticoagulation, neoplastic disease, and end-organ failure without increased morbidity and mortality. CONCLUSIONS In conclusion, the future of MBS lies in the ongoing innovation and adapted therapeutic strategies along with the integration of a variety of other techniques for managing obesity. Careful preoperative assessments, coupled with a multidisciplinary approach, remain essential to ensure optimal surgical outcomes and patient satisfaction after MBS.

Effectiveness of sleeve gastrectomy plus fundoplication versus sleeve gastrectomy alone for treatment of patients with severe obesity: a systematic review and meta-analysis. Surg Obes Relat Dis 2024; 20:532-543.

Abstract
BACKGROUND Laparoscopic sleeve gastrectomy (SG) is a widely performed bariatric surgery, but it is associated with an increased risk of gastroesophageal reflux (GERD) in the long term. The addition of fundoplication to laparoscopic SG may improve lower oesophageal sphincter function and reduce postoperative GERD. OBJECTIVES This systematic review and meta-analysis aims to compare the efficacy and safety of SG plus fundoplication (SG + F) versus SG alone for the treatment of patients with severe obesity (≥35 kg/m2). SETTING Meta-analysis. METHODS Three electronic databases were searched from inception until January 2023. Studies were included if they compared outcomes of SG + F versus SG in patients with severe obesity (≥35 kg/m2). The primary outcome was remission of GERD postoperatively. Secondary outcomes were the percentage of excess weight loss, percentage of total weight loss, postoperative complication rate, operative time, and length of stay. RESULTS A total of 5 studies with 539 subjects (212 SG + F and 327 SG alone) were included. The mean preoperative body mass index was 42.6 kg/m2. SG + F achieved higher remission of GERD compared with laparoscopic SG (odds ratio [OR] = 13.13; 95% CI, 3.54-48.73; I2 = 0%). However, the percentage of total weight loss was lower in the SG + F group (mean difference [MD] = -2.75, 95% CI, -4.28 to -1.23; I2 = 0%), whereas there was no difference in the percentage of excess weight loss (MD = -0.64; 95% CI, -20.62-19.34; I2 = 83%). There were higher postoperative complications in SG + F (OR = 2.56; 95% CI, 1.12-5.87; I2 = 0%) as well. There was no difference in operative time or length of stay between the 2 groups. CONCLUSION SG + F achieved better GERD remission but is associated with lesser weight loss and increased postoperative complications compared with SG alone. Further studies are required to ascertain the overall clinical benefit of SG + F for patients with severe obesity.

Abstract
BACKGROUND Conversion of sleeve gastrectomy to Roux-en-Y gastric bypass is indicated primarily for unsatisfactory weight loss or gastroesophageal reflux disease (GERD). This study aimed to use a comprehensive database to define predictors of 30-day reoperation, readmission, reintervention, or mortality. An artificial neural network (ANN) was employed to optimize prediction of the composite endpoint (occurrence of 1+ morbid event). METHODS Areview of 8895 patients who underwent conversion for weight-related or GERD-related indications was performed using the 2021 MBSAQIP national dataset. Demographics, comorbidities, laboratory values, and other factors were assessed for bivariate and subsequent multivariable associations with the composite endpoint (P ≤ .05). Factors considered in the multivariable model were imputed into a three-node ANN with 20% randomly withheld for internal validation, to optimize predictive accuracy. Models were compared using receiver operating characteristic (ROC) curve analysis. RESULTS 39% underwent conversion for weight considerations and 61% for GERD. Rates of 30-day reoperation, readmission, reintervention, mortality, and the composite endpoint were 3.0%, 7.1%, 2.1%, .1%, and 9.1%, respectively. Of the nine factors associated with the composite endpoint on bivariate analysis, only non-white race (P < .001; odds ratio 1.4), lower body-mass index (P < .001; odds ratio .22), and therapeutic anticoagulation (P = .001; odds ratio 2.0) remained significant upon multivariable analysis. Areas under ROC curves for the multivariable regression, ANN training, and validation sets were .587, .601, and .604, respectively. DISCUSSION Identification of risk factors for morbidity after conversion offers critical information to improve patient selection and manage postoperative expectations. ANN models, with appropriate clinical integration, may optimize prediction of morbidity.

Abstract
PURPOSE This study aims to systematically review and meta-analyze the evidence on the risk of esophageal adenocarcinoma (EAC) following metabolic and bariatric surgery (MBS). MATERIALS AND METHODS A systematic literature search was conducted on the China National Knowledge Infrastructure (CNKI), Wanfang, EMBASE, MEDLINE, Web of Science, The Cochrane Library, and PubMed databases. Meta-analysis utilized odds ratios (ORs) and 95% confidence intervals (CIs) to analyze the correlation between MBS and the risk of EAC. Meta-analysis was performed using STATA software (version 12.0). RESULTS Fourteen studies involving patients with obesity undergoing bariatric surgery and control groups receiving conventional treatment were included. The meta-analysis indicated a reduction in the overall incidence of esophageal cancer after bariatric surgery (OR = 0.69, 95% CI: 0.51-0.95, P = 0.022). Subgroup analysis results demonstrated a decreased risk of EAC in European patients with obesity undergoing MBS treatment (OR: 0.60, 95% CI: 0.38-0.95, P = 0.028). In studies with a sample size greater than or equal to 100,000 patients, the risk of EAC in patients with obesity undergoing MBS was significantly lower than the non-surgery group (OR: 0.59, 95% CI: 0.42-0.83, P = 0.003). Articles published before 2020 and those published in 2020 or earlier showed a significant difference in the incidence of EAC between the surgery and non-surgery groups (OR: 0.57, 95% CI: 0.43-0.75, P < 0.001). The risk of EAC in patients with obesity with a follow-up time of less than 5 years was statistically significant (OR: 0.46, 95% CI: 0.25-0.82, P = 0.009). CONCLUSION Our meta-analysis results suggest a reduced risk of esophageal cancer in patients with obesity after bariatric surgery. PROSPERO REGISTRATION CRD 42024505177.

Abstract
Background: Variable incidences (up to 18.8%) of Barrett's esophagus (BE) have been reported following sleeve gastrectomy (SG), however, there is no published data from the Southeast Asian population. Objective: To determine the incidence of BE following SG in Southeast Asians. Materials and Methods: In this cross-sectional observational study from a tertiary-care center, all patients who had undergone SG from 2008 to 2021 and completed a minimum of 1-year follow-up were contacted to participate. Preoperative data were retrieved from a prospectively maintained database. On recruitment, all patients underwent barium swallow and upper gastrointestinal endoscopy, and weight parameters and reflux symptoms were recorded. Results: One hundred fourteen patients with no preoperative evidence of BE were included. The mean follow-up duration was 5.4 ± 3.1 years. On follow-up endoscopy, Barrett's was suspected in 4 patients. However, 3 patients had columnar-lined epithelium and only 1 patient (0.87%) had evidence of intestinal metaplasia without dysplasia on histology. Reflux esophagitis (grade LA-A) resolved in 9 out of 11 patients, while the rate of de novo esophagitis was reported in 22.3%. The mean reflux Symptom Severity score increased from 0.6 ± 1.8 to 2.6 ± 5.4 (P = .002). The mean body mass index reduced from 44.1 ± 7.1 to 33.6 ± 6.9 kg/m2 (P < .0001), however, 23.7% of the patients experienced significant weight recidivism. Conclusions: Southeast Asians might have a low incidence of BE following SG. Hence, endoscopic surveillance for the sole purpose of diagnosing BE may not be advisable for these patients.

Comparing Safety and Efficacy Outcomes of Gastric Bypass and Sleeve Gastrectomy in Patients With Type 2 Diabetes Mellitus: A Systematic Review and Meta-Analysis. Cureus 2024; 16:e52796. [PMID: 38389648 PMCID: PMC10883263 DOI: 10.7759/cureus.52796] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 01/23/2024] [Indexed: 02/24/2024] Open
Abstract
Sleeve Gastrectomy (SG) could be done by the removal of a big portion of the stomach, leading to reduced amounts of food taken as a result of the smaller stomach size. In contrast, Roux-en-Y Gastric Bypass (RYGB) can be done by creating a small stomach pouch and rerouting a part of the small intestine, employing combined mechanisms of restriction and malabsorption to limit food intake and modify nutrient absorption. Our aim is to identify the most effective and safest surgical intervention for individuals with both Type 2 Diabetes Mellitus (T2DM) and obesity, considering both short and long-term outcomes. We will assess participants undergoing either SG or RYGB to determine the optimal surgical approach. We made a thorough search of PubMed, Cochrane Library, Scopus, and Web of Science databases up to November 2023. Our focus was on randomized controlled trials (RCTs) comparing the safety and efficacy of RYGB and SG in T2DM regarding any extractable data. We excluded studies of other designs, such as cohorts, case reports, case series, reviews, in vitro studies, postmortem analyses, and conference abstracts. Utilizing Review Manager 5.4, we performed a meta-analysis, combining risk ratios (RR) with a 95% confidence interval (CI) conducted for binary outcomes, while mean with SD and 95% CI are pooled for the continuous ones. The total number of participants in our study is 4,148 patients. Our analysis indicates superior outcomes in the group undergoing RYGB surgery compared to the SG group (RR = 0.76, 95% (CI) (0.66 to 0.88), P = 0.0002). The pooled data exhibited homogeneity (P = 0.51, I2 = 0%) after employing the leave-one-out method. For the 1-3 year period, six studies involving 332 patients with T2DM yielded non-significant results (RR = 0.83, 95% CI (0.66 to 1.06), P = 0.14) with homogeneity (P = 0.24, I2 = 28%). Conversely, the 5-10 year period, with six studies comprising 728 DM patients, demonstrated significant results (RR = 0.69, 95% CI (0.56 to 0.85), P = 0.14) and homogeneity (P = 0.84, I2 = 0%). In terms of total body weight loss, our findings indicate significantly higher weight loss with RYGB (mean difference (MD) = -6.13, 95% CI (-8.65 to -3.6), P > 0.00001). However, pooled data exhibited considerable heterogeneity (P > 0.00001, I2 = 93%). Subgroup analyses for the 1-3 year period (five studies, 364 DM patients) and 5-10 year period (six studies, 985 DM patients) also revealed significant differences favoring RYGB, with heterogeneity observed in both periods (1-3 years: P > 0.00001, I2 = 95%; 5-10 years: P = 0.001, I2 = 75%). RYGB demonstrated significant long-term improvement in diabetes remission and superior total body weight loss compared to SG. While no notable differences were observed in other efficacy outcomes, safety parameters require further investigation. no significant distinctions were found in any of the safety outcomes: hypertension (HTN), high-density lipoprotein (HDL), hyperlipidemia, fasting blood glucose, vomiting, low-density lipoprotein (LDL), and total cholesterol. Further research is essential to comprehensively assess safety outcomes for both surgical approaches.

Abstract
Background: We previously described sleeve gastrectomy with jejunoileal bypass (SGJIB) as promising novel technique for the surgical treatment of obesity Methods: A retrospective analysis of a prospective database in a Private Practice of Alimentary Tract Surgery in São Paulo, Brazil. We analyzed 176 patients with 60 months of follow-up, 74 of whom underwent Vertical Sleeve Gastrectomy with Jejunoileal Bypass (VSG-JIB) (50 women and 24 men) with a mean age of 38 years and a mean body mass index (BMI) of 40 kg/m2, and 102 patients underwent Roux-en-Y gastric bypass (RYGB) (90 women and 12 men) with a mean age of 36.5 years and a mean BMI of 39.73 kg/m2. Results: There was no statistically significant difference in long-term weight loss between the two groups. The rate of postoperative complications immediately after surgery was similar, but there was a tendency toward less severe complications in the SGJIB cohort. Conclusion: Sleeve gastrectomy with jejunoileal bypass is a novel surgical procedure for weight loss with comparable efficacy and safety compared with laparoscopic RYGB.

Abstract
PURPOSE The literature on long-term outcomes of duodenal switch (DS) compared to single anastomosis duodenal switch (SADI-S) procedures is lacking. We evaluated the long-term outcomes of SADI-S compared to those after the classic DS procedure. METHODS This is a follow-up report from a single-institution prospective cohort study comparing long-term outcomes of SADI-S versus DS both as one- and two-stage procedures (ClinicalTrials.gov: NCT02792166). Data is depicted as count (percentage) or median (interquartile range). RESULTS Forty-two patients underwent SADI-S, of whom 11 had it as a second-stage procedure (26%). Of 20 patients who underwent DS, twelve had it as a second-stage procedure (60%). Both groups were similar at baseline. Median follow-up times for one-stage SADI-S and DS were 57 (24) and 57 (9) months, respectively (p = 0.93). Similar BMI reductions were observed after one-stage SADI-S (16.5 kg/m2 [8.5]) and DS (18.9 kg/m2 [7.2]; p = 0.42). At median follow-up of 51 (21) and 60 (15) months after second-stage SADI-S and DS, respectively (p = 0.60), surgical procedures yielded reductions in BMI of 20.5 kg/m2 (14.0) and 24.0 kg/m2 (13.9), respectively (p = 0.52). Follow-up rates were similar for one-stage (≥ 88%; p = 0.29) and second-stage procedures (≥ 83%; p = 0.16). Similar diabetes and hypertension remissions were found (p = 0.77; P = 0.54, respectively). Despite fat-soluble vitamin deficiencies at baseline, after supplementation, they were either eliminated or less prevalent long-term after SADI-S. Daily bowel movements were also less frequent. CONCLUSIONS Long-term weight and comorbidity outcomes after SADI-S are similar to those of DS both as one- and two-stage surgeries. SADI-S procedure may allow for similar beneficial outcomes with less burden from gastrointestinal symptoms and fat-soluble vitamin deficiencies.

Abstract
Sleeve gastrectomy has become the most performed bariatric surgery technique in the world. This bariatric technique has been related to the appearance of gastroesophageal reflux and recently with de novo Barrett's esophagus. It is not clear that this leads to an increased incidence of esophageal adenocarcinoma. In this review we analyze the current scientific literature to try to answer the true incidence of Barrett's esophagus and adenocarcinoma after sleeve gastrectomy, and whether these data should make us change the indications for this technique.

Abstract
Early detection of esophageal cancer through endoscopic imaging is pivotal for effective treatment. However, the intricacies of endoscopic diagnosis, contingent on the physician's expertise, pose challenges. Esophageal cancer features often manifest ambiguously, leading to potential confusions with other inflammatory esophageal conditions, thereby complicating diagnostic accuracy. In recent times, computer-aided diagnosis has emerged as a promising solution in medical imaging, particularly within the domain of endoscopy. Nonetheless, contemporary AI-based diagnostic models heavily rely on voluminous data sources, limiting their applicability, especially in scenarios with scarce datasets. To address this limitation, our study introduces novel data training strategies based on transfer learning, tailored to optimize performance with limited data. Additionally, we propose a hybrid model integrating EfficientNet and Vision Transformer networks to enhance prediction accuracy. Conducting rigorous evaluations on a carefully curated dataset comprising 1002 endoscopic images (comprising 650 white-light images and 352 narrow-band images), our model achieved exceptional outcomes. Our combined model achieved an accuracy of 96.32%, precision of 96.44%, recall of 95.70%, and f1-score of 96.04%, surpassing state-of-the-art models and individual components, substantiating its potential for precise medical image classification. The AI-based medical image prediction platform presents several advantageous characteristics, encompassing superior prediction accuracy, a compact model size, and adaptability to low-data scenarios. This research heralds a significant stride in the advancement of computer-aided endoscopic imaging for improved esophageal cancer diagnosis.

Abstract
OBJECTIVE This study aimed to survey international experts in metabolic and bariatric surgery (MBS) to improve and consolidate perioperative interventions to prevent gastroesophageal reflux disease (GERD) and marginal ulcers (MU) after MBS. BACKGROUND Very important long-term complications after MBS include GERD, Barrett's esophagus, and MU. Prevention might be fundamental to reduce the incidence, severe complications, and the increasing number of revisional bariatric surgeries. METHODS An international scientific team designed an online confidential questionnaire with 45 multiple-choice questions. The survey was sent to 110 invited experts and 96 of them (from 41 different countries) participated from 21 July 2022 to 4 September 2022. RESULTS Most experts (≥ 90%) prescribe postoperative acid suppression agents after MBS. Life-long proton pump inhibitors prophylaxis in smokers with avoidance of non-steroidal anti-inflammatory drugs are recommended by most of the experts (66%, 73%) after any type of gastric bypass. Two-thirds of experts (69%) perform Helicobacter pylori eradication prior to MBS. Two-thirds of experts (68%) routinely perform EGD and biopsy before MBS. Follow-up esophagogastroduodenoscopy (EGD) and timing threshold for revisional and conversional MBS were variable among experts. CONCLUSION This expert survey underlines important perioperative interventions that reached a two-thirds consensus among MBS international experts. Variability in follow-up EGD, approach to complication management, and thresholds for revisional and conversional MBS emphasize the need for further researches and consensus guidelines.

[PMID: 37059866 DOI: 10.1007/s11695-023-06599-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2023] [Revised: 04/06/2023] [Accepted: 04/10/2023] [Indexed: 04/16/2023]
Abstract
Sleeve gastrectomy (SG) is deemed a refluxogenic operation but with a low incidence of postoperative Barrett´s esophagus (BE). We aimed to shed some light on the potential paradox of the weak association between SG, BE and esophageal adenocarcinoma (EAC). The high incidence of GERD after SG is not followed by an increased rate of BE and EAC, as these rates are similar to the general population. We hypothesized that this paradox may occur due to a difference in the gastro-esophageal reflux composition secondary to a lower content of bile, to a decrease in inflammation due to weight loss and hormonal changes, and to acquisition of healthier habits such as exercise, smoking cessation, and better eating behavior.

Abstract
BACKGROUND AND OBJECTIVES Gastro-oesophageal reflux disease (GERD) consists in the passage of gastric acid content from the stomach to the oesophagus, causing burns and deteriorating the quality of life. Laparoscopic Sleeve Gastrectomy (LSG) could induce de novo GERD and worsen pre-existing GERD because of the higher gastric pressurisation, reduction of stomach volume and a wider His-angle. In the proposed work, various computational gastric 2D models were developed to understand the effects of variables such as the His-angle, the antral dimension, and the bolus viscosity on the reflux increase. METHODS Fluid-Structure Interaction (FSI) computational models which couple the solid mechanics of the gastric wall, and the fluid domain of the bolus, have been developed to shed light on biomechanical aspects of GERD after LSG. A closure was imposed to the lower oesophageal sphincter (LES) mimicking what happens physiologically after food intake. RESULTS Results showed that the configuration prone to higher reflux flow was the post-surgical 65° model with a staple line starting directly from the pylorus without antral preservation, for all considered viscosities. Increasing viscosity, reflux flow decreased. Post-surgical refluxes were higher than pre-ones and decreased with increasing antrum preservation. CONCLUSIONS These results could be a starting point for analysis of anatomical features, bariatric surgery and GERD occurrence. Further studies based on 3D geometries need to be performed.

Abstract
Importance Bariatric surgery has been associated with a reduced risk of cancer in individuals with obesity. The association of bariatric surgery with esophageal and gastric cancer is still controversial, however. Objective To compare the incidence of esophageal and gastric cancer between patients with obesity who underwent bariatric surgery and those who did not (control group). Design, Setting, and Participants This cohort study obtained data from a national discharge database, including all surgical centers, in France from January 1, 2010, to December 31, 2017. Participants included adults (aged ≥18 years) with severe obesity who underwent bariatric surgery (surgical group) or who did not (control group). Baseline characteristics were balanced between groups using nearest neighbor propensity score matching with a 1:2 ratio. The study was conducted from March 1, 2020, to June 30, 2021. Exposures Bariatric surgery (adjustable gastric banding, gastric bypass, and sleeve gastrectomy) vs no surgery. Main Outcomes and Measures The main outcome was incidence of esophageal and gastric cancer. A secondary outcome was overall in-hospital mortality. Results A total of 303 709 patients who underwent bariatric surgery (245 819 females [80.9%]; mean [SD] age, 40.2 [11.9] years) were matched 1:2 with 605 140 patients who did not receive surgery (500 929 females [82.8%]; mean [SD] age, 40.4 [12.5] years). After matching, the 2 groups of patients were comparable in terms of age, sex, and comorbidities (standardized mean difference [SD], 0.05 [0.11]), with some differences in body mass index. The mean follow-up time was 5.62 (2.20) years in the control group and 6.06 (2.31) years in the surgical group. A total of 337 patients had esophagogastric cancer: 83 in the surgical group and 254 in the control group. The incidence rates were 6.9 per 100 000 population per year for the control group and 4.9 per 100 000 population per year for the surgical group, resulting in an incidence rate ratio of 1.42 (95% CI, 1.11-1.82; P = .005). The hazard ratio (HR) of cancer incidence was significantly in favor of the surgical group (HR, 0.76; 95% CI, 0.59-0.98; P = .03). Overall mortality was significantly lower in the surgical group (HR, 0.60; 95% CI, 0.56-0.64; P < .001). Conclusions and Relevance In this large, nationwide cohort of patients with severe obesity, bariatric surgery was associated with a significant reduction of esophageal and gastric cancer incidence and overall in-hospital mortality, which suggests that bariatric surgery can be performed as treatment for severe obesity without increasing the risk of esophageal and gastric cancer.

Abstract
Esophageal lesions ranging from erosive esophagitis to Barrett's esophagus (BE) eventually develop months-years after sleeve gastrectomy (SG), representing a significant post-surgical issue in GI practice. Roux-en-Y gastric bypass (RYGB) conversion is a widespread and effective method of managing reflux and esophageal complications following SG. Although some studies using a limited sample size have demonstrated that RYGB performed as a primary procedure may regress BE presumably by reducing reflux, whether the same may apply to RYGB performed as revision surgery after SG has scarcely been addressed in the literature. Though histological regression of BE following primary RYGB occurs in 51.9% of patients, with regression of Barrett's dysplasia in 50% of cases, revisional RYGB yields a remission rate as high as 81.8% for Barrett's metaplasia and 100% for dysplastic lesions, although the number of subjects in the published studies are very small. We report two patients who developed GERD and BE following SG with complete regression 12 months after conversion to RYGB in both subjects, confirming the substantially greater proportion of BE resolution in patients undergoing RYGB as revision surgery following SG.

Abstract
PURPOSE Sleeve gastrectomy (SG) is the most common bariatric procedure worldwide. It has been reported that there is a strong association between SG and the development of gastroesophageal reflux disease (GERD) and Barrett's esophagus (BE). This study was conducted to evaluate esophagogastroduodenoscopy (EGD) findings in patients with a history of SG with more than 5-year follow-up. METHODS This is a retrospective cohort study of prospectively maintained database. Inclusion criteria included patients who underwent SG between April 2015 and March 2016, aged 18 and above, BMI ≥ 40 kg/m2. Patients with 5 years of follow-up were invited to take part in the study and underwent EGD and biopsy. RESULTS One hundred twenty-six patients were recruited with a mean age of 44.6 ± 11.1 years. After a 5-year follow-up, there were 31 (29.5%) patients with reflux esophagitis. The grades of GERD were A, B, and C in 16 (15.2), 12 (11.4), and 3 (2.9%) patients, respectively. Incidence of BE was 5.7% after 5 years from SG. There was a 16.6% lost to follow-up at 5 years after SG. CONCLUSION The diagnosis and severity of GERD and the search for BE justify endoscopic surveillance in all long-term post-sleeve patients, regardless of reflux symptoms.

Surg Obes Relat Dis 2022; 19:563-575.

Abstract
BACKGROUND The sleeve gastrectomy (SG) is associated with postoperative gastroesophageal reflux disease (GERD). Higher endoscopic Hill grade has been linked to GERD in patients without metabolic surgery. How preoperative Hill grade relates to GERD after SG is unknown. OBJECTIVE To explore the relationship between preoperative Hill grade and GERD outcomes 2 years after SG. SETTING Academic hospital, United States. METHODS All patients (n = 882) undergoing SG performed by 5 surgeons at a single academic institution from January 2015 to December 2019 were included. Complete data sets were available for 360 patients, which were incorporated in analyses. GERD was defined as the presence of a diagnosis in the medical record accompanied by pharmacotherapy. Patients with GERD postoperatively (n = 193) were compared with those without (n = 167). Univariable and multivariable analyses were conducted to explore independent associations between preoperative factors and GERD outcomes. RESULTS The presence of any GERD increased at the postoperative follow-up of 25.2 (3.9) months compared with preoperative values (53.6% versus 41.1%; P = .0001). Secondary GERD outcomes at follow-up included de novo (41.0%), persistent (33.1%), resolved (28.4%), worsened (26.4%), and improved (12.2%) disease. Postoperative endoscopy and reoperation for GERD occurred in 26.4% and 6.7% of the sample. Patients with GERD postoperatively showed higher prevalence of Hill grade III-IV (32.6% versus 19.8%; P = .0062) and any hiatal hernia (HH) (36.3% versus 25.1%; P = .0222) compared with patients without postoperative GERD. Frequencies of gastritis, esophagitis A or B, duodenitis, and peptic ulcer disease were similar between groups. Higher prevalence of preoperative GERD (54.9% versus 25.1%; P < .0001), obstructive sleep apnea (66.8% versus 54.5%; P = .0171), and anxiety (25.4% versus 15.6%; P = .0226) was observed in patients with postoperative GERD compared with those without it. Baseline demographics, weight, other obesity-associated diseases, whether an HH was repaired at index SG, and follow-up length were statistically similar between groups. After adjusting for collinearity, preoperative GERD (odds ratio [OR] = 3.6; 95% confidence interval [CI], 2.2-5.7; P < .0001) and Hill grade III-IV (OR [95% CI]: 1.9 [1.1-3.1]; P = .0174) were independently associated with the presence of any GERD postoperatively. The preoperative presence of an HH >2 cm and whether an HH was repaired at index SG showed no independent association with GERD at follow-up. CONCLUSIONS More than 50% of patients experienced GERD 2 years after SG. Preoperative GERD confers the highest risk for GERD postoperatively. Hill grade III-IV is independently associated with GERD after SG. Whether a hiatal hernia repair was performed did not influence GERD outcomes. Preoperative esophagogastroduodenoscopy should be obtained before SG and Hill grade routinely captured and used to counsel patients about the risk of postoperative GERD after this procedure. Hill grade may help guide the choice of metabolic operation.

Abstract
BACKGROUND This review aimed to give an updated overview of the occurrence, diagnosis, treatment and outcome of oesophageal and gastric cancer after bariatric and metabolic surgery (BMS). METHODS Two searches were done (one for original studies and one for systematic reviews) using an adapted form of "scoping review methodology". MEDLINE, Embase, CINAHL, Pubmed and the Cochrane Library were searched for studies on patients with either oesophageal or gastric cancer after BMS. RESULTS A total of 52 unique studies were included which reported on 324 patients, which included 110 (34%) males and 136 (42%) females. In the remaining 78 patients, gender was not specified. A mean of 62.95 ± 32.75 months was the time from BMS to diagnosis of cancer. Most of the patients had a Roux-en-Y gastric bypass (RYGB) as index bariatric surgical procedure, followed by gastric banding (GB) and sleeve gastrectomy (SG) (respectively, 133 (41.0%) RYGB, 97 (30.0%) GB and 58 (18.0%) SG). Seven cases have been reported after OAGB-MGB (3 in gastric remnant, 4 in oesophagus/gastric pouch). Seventy-seven (24%) had distant metastasis (≥ M1/Mx status). The majority of tumours were adenocarcinoma (n = 208, 87.4%). In the majority of the cases, a surgical approach was preferred with either adjuvant chemo or radiotherapy. In the course of the disease, 122 of 324 patients died (37.8%). CONCLUSION To our knowledge, this is the most up-to-date review addressing oesophageal and gastric malignancies after bariatric surgery. Future research should focus to optimise screening for oesophageal and gastric cancer after bariatric surgery.

Abstract
INTRODUCTION Erosive esophagitis (EE) occurs when refluxate from the stomach causes T-lymphocyte infiltration of the esophageal mucosa, resulting in mucosal breaks. Currently, therapy with proton-pump inhibitors (PPIs) is the standard treatment for EE in the United States, but few comprehensive reviews exist on the efficacy of PPIs in US populations. Here, we present the most contemporary, thorough analysis of PPI efficacy rates, and identify and characterize patient subgroups at risk for poor healing outcomes. AREAS COVERED We searched the literature to identify studies reporting rates of endoscopic healing and maintained healing of EE with PPI therapies in the US and found a paucity of recent evidence and real-world evidence. Twenty-two studies from 2009 and earlier were included in the final dataset. EXPERT OPINION Rates of EE healing with PPIs were highest after 8 weeks of treatment, with over 80% of patients in most treatment arms demonstrating endoscopic healing, compared to lower efficacy (<80%) at 4 weeks. Rates of maintained healing with PPIs at 6 and 12 months were mostly lower than 80%, although the data were limited. Symptomatic patients and those with severe EE were less likely to achieve healing. Obese patients experienced similar healing rates as non-obese patients.

Abstract
Metabolic surgery has been on the rise over the last 2 decades. As more literature has been being published regarding its efficacy in treating metabolic syndrome as well as advancements in surgical training and safety rise with it, metabolic surgery will in no doubt continue to increase in prevalence. Concomitantly, the prevalence of esophageal cancer is increasing. We present two cases of patients who are status post sleeve gastrectomy and require esophagectomy. These patients do not have the availability of a gastric conduit, and colon interposition graft was planned for their reconstructions. We here review the two unique case scenarios as well as an overview of colon interposition technique and workup considerations. The need this reconstruction technique will likely increase in the years to come and metabolic surgery and esophageal cancer both continue to rise.

Abstract
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. Trial Registration ClinicalTrials.gov Identifier: NCT00793143.

Abstract
Obesity has evolved into a global epidemic. Bariatric surgery, the most effective treatment for obesity, keeps many comorbidities of obesity at bay for a prolonged period of time. However, complications, including metabolic alterations, are inherent in bariatric surgery. Surgical intervention in the structure of the digestive tract, especially during bariatric bypass procedures, also causes significant changes in the composition of the microbiome, which may affect the composition and quantity of various metabolites produced by intestinal bacteria. The composition of the intestinal microbiome is connected to human metabolism via metabolites that are produced and secreted by bacterial cells into the intestinal lumen and then absorbed into the host's bloodstream. Bariatric surgery causes changes in the composition and quantity of many circulating metabolites. Metabolic disorders may be affected after bariatric surgery by changes in the composition of the microbiome and metabolites produced by bacteria.

Predictive Factors for Developing GERD After Sleeve Gastrectomy: Is Preoperative Endoscopy Necessary? J Gastrointest Surg 2022; 26:1015-1020.

Abstract
INTRODUCTION Sleeve gastrectomy (SG) is the most common bariatric procedure performed in the USA. There is a concern for new gastroesophageal reflux disease (GERD) and Barrett's esophagus after SG. Endoscopic screening before bariatric surgery is controversial. We sought to identify preoperative endoscopic factors that may predict the development of GERD after SG. METHODS We prospectively evaluated 217 patients undergoing primary robotic-assisted SG. All patients underwent endoscopy before SG and for-cause postoperatively. Patients were followed for the development of GERD, diagnosed by either biopsy-proven reflux esophagitis or a positive esophageal pH test. Patients were separated into 2 groups: Those who developed GERD after surgery (GERD group) and those who did not (No GERD group). Patients with a positive preoperative pH test, LA Grade B or greater esophagitis, or hiatal hernia > 5 cm on preoperative endoscopy were counseled to undergo gastric bypass and excluded. RESULTS There were more males in the No GERD group (25.6% vs. 8.1%; p = 0.02). More patients had preoperative heartburn symptoms in the GERD group (40.5% vs. 23.9%; p = 0.04). Endoscopically identified esophagitis was more common in the GERD group (29.7% vs. 13.3%; p = 0.01), as was biopsy-proven esophagitis (24.3% vs. 11.1%; p = 0.03). There was no significant difference in the incidence or size of hiatal hernia or in the rate of H. pylori infection between the groups. On multivariate analysis, the strongest predictors of GERD after SG were endoscopically identified esophagitis (odds ratio [OR] 2.79; 95% confidence interval [CI]1.17-6.69; p = 0.02) and biopsy-proven esophagitis (OR 2.80; 95% CI 1.06-7.37; p = 0.04). Male patients were less likely to develop GERD after SG (OR 0.23; 95% CI 0.06-0.85; p = 0.03). CONCLUSION Our findings strengthen the rationale for routine preoperative endoscopy and highlight critical clinical and endoscopic criteria that should prompt consideration of alternatives to SG for weight loss.

Abstract
Objective To investigate the risk factors associated with reflux esophagitis in patients undergoing esophageal cancer surgery and to provide reference for the prevention and treatment of reflux esophagitis. Methods In the manner retrospective study, the data of 300 patients with esophageal cancer who received the surgical treatment in our hospital (January 2018-December 2020) were retrospectively reviewed. The 300 patients were divided into the occurrence group (n = 45) and nonoccurrence group (n = 255) depending on whether they had reflux esophagitis after surgery. The social demographic data and clinical data of the patients in the two groups were collected. These data were classified into the personal factors and surgical factors. The single-factor analysis method was adopted to analyze the effects of the personal and surgical factors on reflux esophagitis. The factors with statistically significant differences in the single-factor analysis were analyzed by logistic regression to verify the factors were the risk factors associated with reflux esophagitis in patients undergoing esophageal cancer surgery. Results The differences in the bodyweight, body mass index (BMI), length of the resected esophagus, surgical approach, intraoperative blood loss, gastrointestinal decompression volume, and surgery time between the two groups were of statistical significance (P < 0.05). After being tested by the logistics multivariate analysis, length of the resected esophagus, whole stomach reconstruction, intraoperative blood loss, and surgery time were identified as the risk factors associated with reflux esophagitis in patients undergoing esophageal cancer surgery. Conclusion The length of the resected esophagus, whole stomach reconstruction, intraoperative blood loss, and surgery time were the risk factors associated with reflux esophagitis in patients undergoing esophageal cancer surgery. It is necessary to choose the appropriate surgical approach according to the patients' conditions in practice and to strengthen the prevention and treatment of reflux esophagitis.

Abstract
Bariatric surgery is now recognized as the most effective treatment of morbid obesity, leading to durable weight loss and resolution of associated co-morbidities. Roux-en-Y gastric bypass and sleeve gastrectomy are the two most widely used operations today. However, potentially serious medical, surgical, and/or psychiatric complications can occur that raise questions regarding the benefits of this type of surgery. These complications can lead to surgical re-operations, iterative hospitalizations, severe nutritional deficiencies and psychological disorders. Indeed, death from suicide is said to be three times higher than in non-operated obese patients. These results are of concern, all the more because of the high prevalence of patients lost to follow-up (for various and multifactorial reasons) after bariatric surgery. However, better knowledge of post-surgical sequelae could improve the information provided to patients, the preoperative evaluation of the benefit/risk ratio, and, for patients undergoing surgery, the completeness and quality of follow-up as well as the detection and management of complications. The development of new strategies for postoperative follow-up such as telemedicine but also the mobilization of all the actors along the healthcare pathway can make inroads and warrant further study.
