Background: Diabetic retinopathy (DR) affects about 25% of people with diabetes in Canada. Early detection of DR is essential for preventing vision loss.
Objective: We evaluated the real-world performance of an artificial intelligence (AI) system that analyzes fundus images for DR screening in a Quebec tertiary care center.
Objective: Patients' ability to judge health change over time has important clinical implications for treatment, but is understudied in longitudinal contexts with meaningful health change. We assess patients' awareness of health change for 5 years following bariatric surgery, and its association with weight loss.
Method: Participants were part of the Longitudinal Assessment of Bariatric Surgery ( = 2,027).
Introduction: This study evaluates the performance of bariatric surgery prior to and after the implementation of Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP).
Methods: The eras prior to (2007-2015) and after (2016-2018) the transition to MBSAQIP were compared for patients, operations and outcomes using adjusted logistic regression estimates.
Results: Thirty-day surgical (6%vs.
Background: Digital replants and revascularization (DRV) have been performed since the 1960s but there are no recognized standard peri-operative anticoagulation practices. A narrative systematic review of the clinical effectiveness and safety of therapeutic peri-operative unfractionated heparin following DRV was undertaken.
Methods: A review of the literature from 1985 to March 2022 was conducted using Medline, Embase, CINAHL and EBM reviews.
Objective: Reliable and simple methods to quantify visceral adipose tissue (VAT) and VAT changes are needed. This study investigated the validity of dual-energy x-ray absorptiometry (DXA) compared with magnetic resonance imaging (MRI) for estimating VAT cross sectionally and longitudinally after surgery-induced weight loss in women with severe obesity.
Methods: Women with obesity (n = 36; mean age 43 [SD 10] years; 89% White) with DXA and MRI before bariatric surgery (T0) at 12 (T12) and 24 months (T24) post surgery were included.
Background: Reporting high-quality bariatric surgery outcomes depends on participant attrition and level of study participation among enrolled participants.
Objectives: Our aims are to report participant attrition, active enrollment, and level of participation, and to evaluate pre-surgery sociodemographic, physical health, and psychosocial factors as predictors of attrition and level of participation through 5 years.
Setting: The Longitudinal Assessment of Bariatric Surgery-2 study which enrolled 2458 adults undergoing a first bariatric surgical procedure at 1 of 6 US cites from 2006 through 2009.
Background: Postbariatric hypoglycemia (PBH) can be a devastating complication for which current therapies are often incompletely effective. More information is needed regarding frequency, incidence, and risk factors for PBH.
Objectives: To examine hypoglycemia symptoms following Roux-en-Y gastric bypass (RYGB) and laparoscopic adjustable gastric banding (LAGB) and baseline and in-study risk factors.
Introduction/purpose: This study evaluates the outcomes of robotic duodenal switch (RDS) when compared to conventional laparoscopy (LDS).
Materials And Methods: Using the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP), patients who underwent RDS were compared to those of LDS (2015-2018) for perioperative characteristics and thirty-day postoperative outcomes. Operative complexity, complications, and resource utilization trends were plotted over the included years for the two approaches.
Background: The frequency of robotic-assisted bariatric surgery has been on the rise. An increasing number of fellowship programs have adopted robotic surgery as part of the curriculum. Our aim was to compare technical efficiency of a surgeon during the first year of practice after completing an advanced minimally invasive fellowship with a mentor surgeon.

Objective: To compare diabetes prevalence and remission rates during 7-year follow-up after Roux-en-Y gastric bypass (RYGB) and laparoscopic gastric banding (LAGB).
Design: An observational cohort of adults with severe obesity recruited between 2006 and 2009 who completed annual research assessments for up to 7 years after RYGB or LAGB.
Introduction/purpose: Reasons of postoperative readmissions may vary based on the timing of rehospitalization. This study characterizes predictors and causes for readmission after bariatric surgery on day-to-day basis after discharge.
Materials And Methods: Using the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program data, patients who underwent Roux-en-Y gastric bypass or sleeve gastrectomy were identified.
Objective: This study aimed to examine whether pregnancy following bariatric surgery affects long-term maternal weight change and offspring birth weight.
Methods: Using data from the Longitudinal Assessment of Bariatric Surgery (LABS)-2 study, linear regression was used to evaluate percent change in total body weight over a 5-year follow-up period among reproductive-aged women who underwent Roux-en-Y gastric bypass or laparoscopic adjustable gastric banding as well as evaluate the association of bariatric procedure type and offspring birth weight.
Results: Of 727 women with preoperative age of 36.
Background: Sleeve gastrectomy (SG) is the most common bariatric operation in the United States but increases the incidence of gastroesophageal reflux disease (GERD). The aim of our study was to describe our experience with robotic-assisted management of intractable GERD after SG.
Methods: A systematic review of a prospectively maintained database was performed of consecutive patients undergoing robotic-assisted magnetic sphincter augmentation placement after sleeve gastrectomy (MSA-S group) or conversion to Roux-en-Y gastric bypass (RYGB group) for GERD from 2015 to 2019 at our tertiary- care bariatric center.
Background: Poly-4-hydroxybutyric acid (P4HB, Phasix™) is a biosynthetic polymer that degrades by hydrolysis that can be woven into a mesh for use in soft tissue reinforcement. Herein, we describe our initial experience performing complex abdominal wall repair (CAWR) utilizing component separation and P4HB mesh as onlay reinforcement.
Methods: All patients undergoing CAWR between June 2014 and May 2017 were followed prospectively for postoperative outcomes.
Article Synopsis
- The study aimed to assess smoking habits and changes in smoking behavior from one year prior to seven years following Roux-en-Y gastric bypass (RYGB) surgery, while identifying risk factors for post-surgery smoking.
- Nearly half of the participants reported a smoking history before surgery, with a significant drop in current smoking rates at the time of surgery, but a gradual increase in smoking prevalence was observed in the following years.
- Factors such as younger age, low household income, marital status, and illicit drug use were found to be linked to a higher risk of resuming smoking after surgery.
Background: Several studies have demonstrated that minorities and Hispanic ethnicities have disproportionally greater burden of morbid obesity in the United States. However, the majority of bariatric procedures are performed in the non-Hispanic white population.
Objectives: The objective of this study was to investigate the weight loss and remission of obesity-related co-morbidities based on race and ethnicity.
Introduction: Bariatric surgery-induced weight loss may reduce resting energy expenditure (REE) and fat-free mass (FFM) disproportionately thereby predisposing patients to weight regain and sarcopenia.
Methods: We compared REE and body composition of African-American and Caucasian Roux-en-Y gastric bypass (RYGB) patients after surgery with a group of non-operated controls (CON). REE by indirect calorimetry; skeletal muscle (SM), trunk organs, and brain volumes by MRI; and FFM by DXA were measured at post-surgery visits and compared with CON (N = 84) using linear regression models that adjusted for relevant covariates.
Article Synopsis
- Patients who undergo bariatric surgery have lower overall mortality rates compared to similar individuals who do not have the surgery, but it's uncertain how their mortality compares to the general population.
- The study aimed to compare post-bariatric surgery mortality rates with those of the general U.S. population, using a cohort of 2,458 adults over a 6.6-year median follow-up period.
- Results showed that the observed mortality post-surgery was similar to expected mortality in the general population, but younger patients (ages 35-44) had higher mortality rates, while older patients (55+) had lower rates than expected, particularly in early postoperative periods.
Bariatric Surgery Among Medicare Subgroups: Short- and Long-Term Outcomes.
Obesity (Silver Spring)
November 2019
Objective: This study sought to examine weight change, postoperative adverse events, and related outcomes of interest among age-qualified (AQ) and disability-qualified (DQ) Medicare recipients compared with non-Medicare (NM) patients undergoing an initial bariatric procedure.
Methods: The Longitudinal Assessment of Bariatric Surgery (LABS-2) is an observational cohort study of 2,458 adults who underwent Roux-en-Y gastric bypass (RYGB) or laparoscopic adjustable gastric banding (LAGB) bariatric surgery. Weight, percentage body fat, functional status, and comorbidities, as well as postoperative adverse events, were assessed at baseline and annually for 5 years.
Background: Some studies suggest that changes in weight or metabolic outcomes are affected by the lengths of the gastrointestinal limbs in the Roux-en-Y gastric bypass.
Methods: Participants (N = 1,770) underwent primary Roux-en-Y gastric bypass and were followed ≤7 years in the Longitudinal Assessment of Bariatric Surgery-2, a multicenter US cohort study. Alimentary limb and biliopancreatic limb lengths were measured according to research protocol; common channel was measured in a subsample (N = 547).
Rationale & Objective: The association between bariatric surgery, type 2 diabetes, and chronic kidney disease (CKD) is poorly understood. We studied whether remission of type 2 diabetes induced by bariatric surgery influences markers of kidney disease, if CKD is associated with remission of diabetes after bariatric surgery, and if baseline levels of gut hormones and peptides modify these associations.
Study Design: Prospective observational study.
Background: Weight loss surgery is safe and effective, but fluid and electrolyte balance remains problematic postoperatively. We developed a mobile app to help patients recover after weight loss surgery.
Material And Methods: Single-center prospective, mixed-methods, participatory research design study of eligible English-speaking adults undergoing weight loss surgery was used.
We report an appendiceal collision tumour in a 23-year-old woman who presented with constipation and abdominal fullness. Imaging revealed a right lower quadrant abdominal mass that was laparoscopically resected. Histology revealed an appendiceal collision tumour composed of a low-grade mucinous neoplasm and well-differentiated neuroendocrine neoplasm.
