Endoscopic management of bariatric surgery complications

Obesity is a global epidemic that has significant impact on morbidity, mortality, and rising health care costs. In morbidly obese patients with body mass index >40 kg/m², bariatric surgery is a grade A recommendation and is associated with up to 40% reduction in premature death. Increasingly, endoscopy is seen as a safer and more cost-effective approach to the management of weight loss surgery complications including gastrointestinal bleeding, development of anastomotic ulcers, staple-line leaks and fistulas, strictures, weight regain, bezoars, choledocholithiasis, and gastric band erosion and slippage. Many endoscopic interventions currently rely on a combination of specialized equipment, such as stents, suture systems, clips, and balloon dilators to successfully treat these issues. This article will present common postoperative complications in bariatric surgery, discuss the latest evidence for their endoscopic management, and offer future directions in the endoluminal therapy of obese patients.
