Complications of Metabolic and Bariatric Surgery for the Gastroenterologist: A Comprehensive Review.

Abstract

By 2035, more than one-half of the global population is expected to have overweight or obesity, amounting to a substantial $4 trillion toll on the global economy. The uptake of metabolic and bariatric surgery has increased worldwide, providing treatment for both obesity and associated disorders of metabolic function. Laparoscopic sleeve gastrectomy and Roux-en-Y gastric bypass are the most commonly performed metabolic and bariatric surgical procedures. Despite advances in surgical techniques, complications are common and can occur long after surgery. This article provides gastroenterologists with a comprehensive compendium for understanding and managing the complications associated with metabolic and bariatric surgery.
