Chronic pancreatitis secondary to an inflammatory polyp of the duodenum 25 years after Billroth II reconstruction.

A 51-year-old man, 25 years after undergoing Billroth II gastrojejunostomy with antrectomy and vagotomy, came to our hospital with acute relapsing pancreatitis. At operation he was found to have an inflammatory polypoid lesion at the duodenal stump that consisted of suture and talc granuloma from his previous gastric surgery. The polyp intermittently obstructed the pancreatic duct, causing symptomatic pancreatitis. The patient has remained without symptoms 2 years after submucosal resection of this polyp. This complication of Billroth II gastroenterostomy has not been recognized previously.
