Fat Mass Index Effectively Predicts Weight Loss Post-Surgery

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 […]

Same-day discharge for anastomotic bariatric surgeries shows promising outcomes

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 […]

Endoscopic sleeve gastroplasty shows comparable outcomes to surgery

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 […]

Machine learning models outperform traditional risk scores in bariatric surgery

Advanced machine learning techniques, particularly random forest, demonstrated superior performance in predicting 30-day complications in metabolic bariatric surgery compared to the established MBSAQIP risk score. The random forest model achieved an area under the receiver operating characteristic curve (AUROC) of 0.94 in training and 0.88 in validation. Key predictive features included serum alkaline phosphatase, platelet […]

Preoperative anticoagulation increases postoperative morbidity in bariatric patients

A recent analysis of 1,178,090 patients reveals that those undergoing sleeve gastrectomy or Roux-en-Y gastric bypass with preoperative therapeutic anticoagulation face significantly higher risks of postoperative complications. Specifically, these patients exhibited increased rates of anastomotic leaks, deep vein thrombosis, and gastrointestinal bleeding, as well as longer operative times and hospital stays. Moreover, sleeve gastrectomy patients […]

Metabolic and bariatric surgery significantly reduces insulin dependency in diabetes.

In a study of 287 patients with insulin-treated type 2 diabetes, metabolic and bariatric surgery (MBS) showed remarkable efficacy. At five years post-surgery, insulin dependence dropped from complete dependency to 36.2%, and the use of non-insulin antidiabetic drugs decreased from 79.4% to 26.1%. Additionally, type 2 diabetes remission rates were highest after biliopancreatic diversion with […]

Endoscopic sleeve gastroplasty shows cost-effectiveness for obesity treatment

Endoscopic sleeve gastroplasty (ESG) demonstrated cost-effectiveness compared to lifestyle modification in adults with class I/II obesity within a five-year horizon, achieving an incremental cost-effectiveness ratio of $23,432 per quality-adjusted life year (QALY). ESG remained cost-effective across sensitivity analyses and was dominant over longer timeframes. The findings suggest ESG as a viable treatment alternative for individuals […]

Laparoscopic Roux-en-Y gastric bypass offers superior weight loss

At five years post-surgery, laparoscopic Roux-en-Y gastric bypass (LRYGB) achieved significantly greater weight loss compared to laparoscopic sleeve gastrectomy (LSG) with a mean difference of -7.65 kg/m² (p=0.0001). The LRYGB group also exhibited better resolution rates for type 2 diabetes mellitus (T2D) and dyslipidemia. Although both procedures showed no difference in quality of life or […]
