Metabolic and Bariatric Surgery

This collection showcases recent advances in metabolic and bariatric surgery, highlighting innovations in operative techniques, perioperative care, and long-term metabolic outcomes. The featured studies examine comparative effectiveness of bariatric procedures, patient selection and risk stratification, same-day discharge, revisional operation, and emerging technologies including robotic surgery, artificial intelligence, and magnetic compression anastomosis. Collectively, these articles underscore the continued evolution of evidence-based, multidisciplinary approaches to optimize safety, long-term outcomes, and access to care for patients with obesity.

Collaborative Approach Toward Transplant Candidacy for Obese Patients with End-Stage Renal Disease

Bariatric surgery offers a pathway to transplant for obese ESRD patients. ESRD patients have unique complications post bariatric surgery. This collaboration reduces healthcare disparities and offers improved long-term outcomes for transplant.

Continued Diabetes Remission Despite Weight Recurrence: Gastric Bypass Long-Term Metabolic Benefit

The odds of type 2 diabetes (T2DM) recurrence after weight recurrence following sleeve gastrectomy is 5.5 times higher than gastric bypass. The discrepancy in continued diabetes remission rates between procedures suggests a substantial role of the proximal small intestine in T2DM remission and sustenance.

Metabolic and Bariatric Operation and the Path to Kidney Transplantation

MBS significantly improves access to kidney transplantation and long-term survival for obese ESRD patients. Patients who underwent MBS demonstrated notable improvements in cardiovascular health, potentially leading to a better quality of life and survival.
