Endoscopy and upper gastrointestinal contrast studies are complementary in evaluation of weight regain after bariatric surgery

EGD and UGI contrast studies are complementary in the evaluation of patients with weight regain after bariatric surgery. The combination of the 2 studies detected all the gastrogastric fistulas present. EGD provided more useful pouch and stomal information, and the UGI study detected esophageal or Roux limb abnormalities that frequently require additional evaluation.
