A systematic review and meta-analysis of 21 studies revealed that metabolic and bariatric surgeries (MBS) substantially lower cancer risk in obese patients compared to non-surgical treatments. Specifically, MBS showed protective effects against colorectal (mean effect size -.28), uterine (mean effect size -.42), breast (mean effect size -.37), and esophageal cancers (mean effect size -.23). Overall, […]

In a retrospective cohort study of 91,708 patients with metabolic dysfunction-associated steatotic liver disease and cirrhosis, bariatric surgery markedly decreased mortality risks. Those who underwent the procedure showed a 5-year overall mortality of 24.9%, compared to 37.1% in non-surgical counterparts. Significant reductions were also observed in liver-related (3.3% vs. 14%) and non-liver-related mortality (22.3% vs. […]

Implementation of the Enhanced Recovery After Surgery (ERAS) program in bariatric procedures significantly reduced hospital stay, costs, and unplanned readmissions. A study comparing pre-ERAS and post-ERAS cohorts revealed a median length of stay decrease by one day and an average cost reduction of $2,230. Additionally, the post-ERAS group exhibited a 52% lower risk of 30-day […]

A systematic review of 11 randomized controlled trials involving 2,323 patients indicates that both sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) show comparable hypertension remission within the first four years post-surgery. However, RYGB demonstrated a significantly greater effectiveness in achieving remission at five years or more, with a relative risk of 1.39. These findings […]

A randomized, placebo-controlled trial demonstrated that liraglutide 3.0 mg significantly combats weight regain after Roux-en-Y gastric bypass, with 76% of subjects achieving at least a 5% total body weight loss compared to 17% in the placebo group. Notably, 21% of liraglutide recipients exceeded their postoperative nadir weight. Throughout the study, nonserious adverse events were reported […]

A modified Delphi process yielded 94 consensus statements on optimising peri-operative care for patients with obesity undergoing non-bariatric surgery. Key pre-operative strategies include access to prehabilitation and risk stratification tools, while intra-operative focus centres on the roles of anaesthetists and surgeons, minimally invasive techniques, and infection prevention. Post-operative care emphasises analgesia, nutritional support, and physiotherapy. […]

Analysis of nearly 1 million patients revealed specific factors predicting postoperative bleeding after minimally invasive bariatric surgeries. Key predictors identified include preoperative anticoagulation, renal insufficiency, history of deep vein thrombosis (DVT) and pulmonary embolism (PE), presence of a cardiac stent, and a BMI of 40 or less. These associations were consistently observed across both laparoscopic […]

Fat mass index (FMI) significantly predicts early weight loss and quality of life following laparoscopic sleeve gastrectomy (LSG). In a study involving 243 patients, FMI demonstrated superior predictive ability compared to other body composition indicators, with an area under the curve of 0.813. Patients with low FMI experienced greater early eligible weight loss and improved […]

A study involving 208 patients from a high-volume Canadian center assessed early outcomes of same-day discharge (SDD) following various anastomotic metabolic and bariatric surgeries. Results demonstrated low rates of unplanned overnight stays, readmissions, and reinterventions. With a mean patient age of 41.4 years and a preoperative BMI of 41.9 kg/m², these findings suggest that SDD […]

A retrospective analysis of patients undergoing endoscopic sleeve gastroplasty (ESG) versus laparoscopic sleeve gastrectomy (LSG) revealed similar improvements in obesity-related comorbidities. While LSG resulted in greater percentage total body weight loss at 6 months, 1 year, and 2 years, ESG was associated with shorter hospital stays and fewer severe adverse events. Patients undergoing ESG were […]
