Presurgical GI evaluation in bariatric surgery

The importance of preoperative endoscopy depends on whether it changes or affects operative management. There is insufficient data to strongly recommend routine endoscopy on all patients planning to undergo bariatric surgery. However, most experts recommend routine preoperative endoscopy in all symptomatic patients as well as to maintain a low threshold for asymptomatic patients. The threshold for preoperative testing also depends on resources available to the health system and the prevalence of significant upper GI pathology in that particular geographic location around the world.
