Background: One anastomosis gastric bypass (OAGB) may expose the patient to certain specific complications. Here, we report the results of conversion of OAGB to Roux-en-Y gastric bypass (RYGB) in terms of outcomes and weight loss.

Methods: Between January 2009 and January 2019, all patients undergoing conversion of OAGB to RYGB because of complications due to OAGB (n = 23) were included.

Prospective comparison of transient elastography, MRI and serum scores for grading steatosis and detecting non-alcoholic steatohepatitis in bariatric surgery candidates.

Background & Aims: Tools for the non-invasive diagnosis of non-alcoholic steatohepatitis (NASH) in morbidly obese patients with suspected non-alcoholic fatty liver disease (NAFLD) are an unmet clinical need. We prospectively compared the performance of transient elastography, MRI, and 3 serum scores for the diagnosis of NAFLD, grading of steatosis and detection of NASH in bariatric surgery candidates.

Methods: Of 186 patients screened, 152 underwent liver biopsy, which was used as a reference for NAFLD (steatosis [S]>5%), steatosis grading and NASH diagnosis.

Bariatric Surgery in Patients With Inflammatory Bowel Disease: A Case-Control Study from the GETAID.

Background: The prevalence of obesity and the number of bariatric surgeries in both the general population and in patients with inflammatory bowel disease (IBD) have increased significantly in recent years. Due to small sample sizes and the lack of adequate controls, no definite conclusions can be drawn from the available studies on the safety and efficacy of bariatric surgery (BS) in patients with IBD. Our aim was to assess safety, weight loss, and deficiencies in patients with IBD and obesity who underwent BS and compare findings to a control group.

Hepcidin and Iron Deficiency in Women One Year after Sleeve Gastrectomy: A Prospective Cohort Study.

Iron deficiency with or without anemia, needing continuous iron supplementation, is very common in obese patients, particularly those requiring bariatric surgery. The aim of this study was to address the impact of weight loss on the rescue of iron balance in patients who underwent sleeve gastrectomy (SG), a procedure that preserves the duodenum, the main site of iron absorption. The cohort included 88 obese women; sampling of blood and duodenal biopsies of 35 patients were performed before and one year after SG.

Endoscopic Management of Bariatric Surgery Complications According to a Standardized Algorithm.

Background And Aims: Endoscopy is effective in management of bariatric surgery (BS) adverse events (AEs) but a comprehensive evaluation of long-term results is lacking. Our aim is to assess the effectiveness of a standardized algorithm for the treatment of BS-AE.

Patients And Methods: We retrospectively analyzed 1020 consecutive patients treated in our center from 2012 to 2020, collecting data on demographics, type of BS, complications, and endoscopic treatment.

Endoscopic internal drainage for the management of leak, fistula, and collection after sleeve gastrectomy: our experience in 617 consecutive patients.

Background: Endoscopy plays a pivotal role in the management of adverse events (AE) following bariatric surgery. Leaks, fistulae, and post-operative collection after sleeve gastrectomy (SG) may occur in up to 10% of cases.

Objectives: To evaluate the efficacy and safety of endoscopic internal drainage (EID) for the management of leak, fistula, and collection following SG.

Five-Year Survival Outcomes of Hybrid Minimally Invasive Esophagectomy in Esophageal Cancer: Results of the MIRO Randomized Clinical Trial.

Importance: Available data comparing the long-term results of hybrid minimally invasive esophagectomy (HMIE) with that of open esophagectomy are conflicting, with similar or even better results reported for the minimally invasive esophagectomy group.

Objective: To evaluate the long-term, 5-year outcomes of HMIE vs open esophagectomy, including overall survival (OS), disease-free survival (DFS), and pattern of disease recurrence, and the potential risk factors associated with these outcomes.

Design, Setting, And Participants: This randomized clinical trial is a post hoc follow-up study that analyzes the results of the open-label Multicentre Randomized Controlled Phase III Trial, which enrolled patients from 13 different centers in France and was conducted from October 26, 2009, to April 4, 2012.

Bariatric surgery induces a new gastric mucosa phenotype with increased functional glucagon-like peptide-1 expressing cells.

Glucagon-Like Peptide-1 (GLP-1) undergoes rapid inactivation by dipeptidyl peptidase-4 (DPP4) suggesting that target receptors may be activated by locally produced GLP-1. Here we describe GLP-1 positive cells in the rat and human stomach and found these cells co-expressing ghrelin or somatostatin and able to secrete active GLP-1 in the rats. In lean rats, a gastric load of glucose induces a rapid and parallel rise in GLP-1 levels in both the gastric and the portal veins.

Efficacy and Safety of the Duodeno-Jejunal Bypass Liner in Patients With Metabolic Syndrome: A Multicenter Randomized Controlled Trial (ENDOMETAB).

Objective: The aim of this study was to compare the efficacy and safety of 12-month implantation of a duodeno-jejunal bypass liner (DJBL) with conventional medical care in patients with metabolic syndrome (MS).

Summary Background Data: DJBL is an endoscopic device for treating obesity and related disorders. The persistence of favorable results after 6 months has not been tested in a controlled study.

Enteral versus parenteral nutrition in the conservative treatment of upper gastrointestinal fistula after surgery: a multicenter, randomized, parallel-group, open-label, phase III study (NUTRILEAK study).

Background: Postoperative upper gastrointestinal fistula (PUGIF) is a devastating complication, leading to high mortality (reaching up to 80%), increased length of hospital stay, reduced health-related quality of life and increased health costs. Nutritional support is a key component of therapy in such cases, which is related to the high prevalence of malnutrition. In the prophylactic setting, enteral nutrition (EN) is associated with a shorter hospital stay, a lower incidence of severe infectious complications, lower severity of complications and decreased cost compared to total parenteral nutrition (TPN) following major upper gastrointestinal (GI) surgery.

Sleeve gastrectomy as a rescue of failed gastric banding: comparison of 1- and 2-step approaches.

Background: Series comparing gastric banding (GB) removal and sleeve gastrectomy (SG) when procedures are performed as a 1- or a 2-step approach are contradictory in their outcomes. No series comparing these approaches with midterm weight loss is available.

Objectives: Compare the outcomes and weight loss of SG performed as 1- and 2-step approaches as a revisional procedure for GB failure.

Long-term consequences of one anastomosis gastric bypass on esogastric mucosa in a preclinical rat model.

Although bariatric surgery is proven to sustain weight loss in morbidly obese patients, long-term adverse effects have yet to be fully characterized. This study compared the long-term consequences of two common forms of bariatric surgery: one-anastomosis gastric bypass (OAGB) and Roux-en-Y Gastric Bypass (RYGB) in a preclinical rat model. We evaluated the influence of biliopancreatic limb (BPL) length, malabsorption, and bile acid (BA) reflux on esogastric mucosa.

Video Report: "Laparoscopic Reversal of Roux-en-Y Gastric Bypass to Normal Anatomy".

Background: Roux-en-Y gastric bypass (RYGB) is considered the gold standard for surgical management of morbid obesity due to its good results on weight loss and correction of comorbidities related to obesity. However, RYGB could have some adverse effect in the mid and long term. Here, we describe simple technique for laparoscopic reversal of RYGB into normal anatomy.

Clinicopathological and Molecular Study of Peritoneal Carcinomatosis Associated with Non-Small Cell Lung Carcinoma.

To retrospectively characterize the molecular features of Non-Small Cell Lung Carcinomas (NSCLC) with peritoneal carcinomatosis (PC), clinicopathological data of 12 patients diagnosed with NSCLC and PC between 2007 and 2016 were collected. Immunohistochemistry and Next Generation Sequencing (NGS) were performed on cases with available material. PC was the initial presentation of NSCLC in 17% of the cases.

Health-related Quality of Life Following Hybrid Minimally Invasive Versus Open Esophagectomy for Patients With Esophageal Cancer, Analysis of a Multicenter, Open-label, Randomized Phase III Controlled Trial: The MIRO Trial.

Background: Hybrid minimally invasive esophagectomy (HMIE) has been shown to reduce major postoperative complications compared with open esophagectomy (OE) for esophageal cancer.

Objectives: The aim of this study was to compare short- and long-term health-related quality of life (HRQOL) following HMIE and OE within a randomized controlled trial.

Methods: We performed a multicenter, open-label, randomized controlled trial at 13 study centers between 2009 and 2012.
