Abstract

Bariatric surgery is an effective treatment for obesity and its metabolic related disorders. With the numbers of bariatric procedures being performed rising annually endoscopists are now more likely than ever to encounter this patient cohort on routine diagnostic lists. Endoscopy plays a vital role in both the pre and postoperative periods to diagnose and treat certain complications associated with bariatric surgery. Preoperative endoscopy may be useful in identifying pathologies that then influence the type of bariatric surgery being proposed. Postoperative endoscopy has an established role in identifying and managing complications such as anastomotic leaks and gastrointestinal bleeding. As endoscopic techniques develop, these complications may be managed without the need for surgical intervention or revision. Increased knowledge and awareness of the indications for endoscopy, together with the altered anatomy and common complications of bariatric surgery, is paramount in managing these patients effectively.
