Background: Ambulatory bariatric surgery has recently gained interest especially as a potential way to improve access for eligible patients with severe obesity. Building on our previously published research, this follow-up study delves deeper in the evolving landscape of ambulatory bariatric surgery over a 3-year period, focusing on predictors of success/failure.

Methods: In a prospective single-center follow-up study, we conducted a descriptive assessment of all eligible patients as per our established protocol, who underwent a planned same-day discharge (SDD) primary sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) between 03/01/2021 and 02/29/2024.

Aim: To validate the Individualized Metabolic Surgery (IMS) score and assess long-term remission of type 2 diabetes (T2D) after duodenal switch (DS)-type procedures in patients with obesity. In addition, to help guide metabolic procedure selection for those patients categorized as having severe T2D.

Materials And Methods: This is a retrospective single cohort study of all patients with T2D and severe obesity, who underwent DS-type procedures at a single institution from December 2010 to December 2018.

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.

Background: Given its short procedure time and low morbidity, there is enthusiasm to perform sleeve gastrectomy (SG) in an outpatient setting. However, most relevant studies include an overnight stay at a medical facility (≤ 24-h). Hence, we investigated the feasibility and safety of a same-day discharge (SDD) protocol for laparoscopic SG.

Background: Kidney transplantation (KT) is the preferred therapy for end-stage renal disease (ESRD). While a major cause for ESRD, obesity is also a key obstacle to candidacy for KT. Bariatric surgery, particularly sleeve gastrectomy (SG), is increasingly used to improve access to KT in patients with obesity, but the literature especially on outcomes post-KT remains lacking.

Background: The literature on long-term impact of bariatric/metabolic surgery on incidence of major adverse cardiovascular events (MACE) in patients with obesity and metabolic syndrome is still lacking. We aimed to evaluate the long-term relationship between metabolic surgery and MACE in such patients.

Methods: In a population-based cohort study, we compared all patients with obesity, diabetes mellitus (DM) and/or hypertension (HTN), who underwent bariatric surgery in Quebec, Canada during 2007-2012, with matched controls with obesity.

Background: Sleeve gastrectomy (SG) is the most common bariatric surgery; however, this approach may induce gastroesophageal reflux disease (GERD). Both obesity and GERD are independent risk factors for esophageal cancer, however the impact of SG on risk of esophageal cancer remains unknown.

Objective: To evaluate the risk of esophageal cancer after reflux-prone bariatric surgery.

Background: Single anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S) is a modification of the classic duodenal switch (DS). These modifications are intended to address concerns about DS, including malnutrition, longer operative times, and technical challenges, while preserving the benefits.

Objectives: To evaluate safety and outcomes of SADI-S as it compares to classic DS procedure.

Background: Sleeve gastrectomy (SG) is the most common primary bariatric surgery. Long-term, up to 20% of patients may need revisional surgery. We aimed to evaluate the short-term outcomes of various revisional bariatric surgeries after a failed primary SG.

Background: Outcomes after bariatric surgery are tied to surgical volume; however, this relationship is not clearly established for each procedure.

Objectives: To evaluate the impact of surgeon/hospital volumes on morbidity after bariatric surgery and identify volume cutoffs.

Setting: Multi-centric population-level study, province of Quebec, Canada.

Background: Obese individuals suffering from advanced chronic kidney disease (CKD) may be precluded from accessing kidney transplantation. Bariatric surgery is an effective treatment for obesity and related conditions but its use in those with severe CKD remains limited due to morbidity concerns. We aimed to evaluate the safety and efficacy of sleeve gastrectomy (SG) in patients with severe CKD as a bridging strategy towards kidney transplant candidacy.

Background: Despite an increase in bariatric surgery across Quebec, Canada, access is still limited. Furthermore, there are differences in resources and multidisciplinary capabilities of providing centers that may impact quality of care and outcomes.

Methods: We performed an online survey of all bariatric surgeons in the province of Quebec, Canada, using the LimeSurvey software.

Background: Indications and outcomes of bariatric surgery in older adults suffering from morbid obesity remain controversial. We aimed to evaluate safety and medium to long-term outcomes of bariatric procedures in this patient population.

Setting: University Hospital, Canada.

Background: Weight recidivism after Roux-en-Y gastric bypass (RYGB) is a common problem. Often, this weight loss failure or regain may be due to a wide gastrojejunostomy (GJ). We evaluated the feasibility and safety of a novel approach of laparoscopic wedge resection of gastrojejunostomy (LWGJ) for a wide stoma after RYGB associated with weight recidivism.

Background: Over the past two decades, there has been a significant rise in bariatric surgery. As a consequence, the prevalence of obese patients with a combined gastric pathology such as a submucosal tumor (SMT) requiring excision at the same time as bariatric surgery is higher but the management remains controversial. We report the safety and effectiveness of a simultaneous laparoscopic transgastric resection of a large gastric SMT near the esophagogastric junction (EGJ) with sleeve gastrectomy (SG).

Introduction: The risk of urolithiasis post-Roux-en-Y gastric bypass (RYGB) surgery is higher when compared to the general population. Calcium and vitamin D supplementation is routinely prescribed to these patients, yet compliance with these supplements is unknown. The aim of this study was to assess the incidence of symptomatic de novo urolithiasis post-RYGB and compliance with calcium and vitamin D supplementation.

Unlabelled: A new measurement tool, the automated software CoreScan, for the GE Lunar iDXA, has been validated for measuring visceral adipose tissue (VAT) against computed tomography in normal-weight populations. However, no study has evaluated the precision of CoreScan in measuring VAT among severely obese patients.

Purpose: The purpose of the study was to evaluate the precision of CoreScan for VAT measurements in severely obese adults (body mass index > 40 kg·m(-2)).

No study has evaluated the precision of the GE Lunar iDXATM (GE Healthcare) in measuring bone mineral density (BMD) among severely obese patients. The purpose of the study was to evaluate the precision of the GE Lunar iDXATM for assessing BMD, including the lumbar spine L1-L4, L2-L4, the total hip, femoral neck, and total body in a severely obese population (body mass index [BMI]>40 kg/m(2)). Sixty-four severely obese participants with a mean age of 46 ± 11 yr, BMI of 49 ± 6 kg/m(2), and a mean body mass of 136.

Background: The Obesity Surgery Mortality Risk Score (OS-MRS) has been proposed as a user-friendly tool for the assessment and risk stratification of patients undergoing Roux-en-Y gastric bypass (RYGB). We assessed the validity of the OS-MRS in 2121 primary RYGB procedures performed at our center during a 25-year period.

Methods: A retrospective study of the patients who had undergone primary RYGB since 1983 was performed.
