The use of endoscopy after gastric partitioning for morbid obesity.

Fiberoptic endoscopy is an important diagnostic modality for evaluating the patient with upper gastrointestinal tract symptoms following gastric restrictive operations. The specific indications for endoscopy after obesity surgery include stoma evaluation in patients who fail to lose adequate weight; stomal stenosis; esophagitis; surveillance of the excluded pouch; and suspicion of a marginal ulcer after gastric bypass.
