Description

The case is a 69-year-old man on hemodialysis for chronic renal failure who routinely takes aspirin. He was hospitalized with black stool and anemia. In his stomach, gastric ulcer was observed endoscopically. We provided conservative medical treatment and confirmed healing tendency of the lesion. However black stool reappeared within 8 days, a Dieulafoy's lesion of the ascending colon was found through colonoscopy and stopped bleeding by endoscopic hemoclip therapy. Thereafter, progress of anemia came to halt and black stool subsided after a few days. A Dieulafoy's lesion of the colon is relatively rare and difficult to diagnose due to the nature. The case is regarded as instructive in that we should consider the disorder when source of gastrointestinal bleeding is difficult to identify.
