Abstract
Gastrojejunocolic fistula caused by stomal ulcers after gastrectomy is rare and one of the serious complications of stomal ulcer. A 74-year-old man was carried out distal gastrectomy with Billroth Ⅱ reconstruction for duodenal ulcer in 1967. He visited another hospital for tarry stool in January 2013. Upper gastrointestinal endoscopy revealed active stomal ulcer, and he started using proton pump inhibitor. He was reffered to our hospital with complaints of diarrhea and weight loss in June 2013. Upper gastrointestinal series and colonoscopy showed the gastrojejunocolic fistula. Partial resection of the remnant stomach, small intestine and transverse colon was performed, resulting improvement of diarrhea and poor nutrition. This disease should be considered when the patient presents diarrhea and weight loss after gastrectomy.
