The case reported here was a 69-year-old man who was admitted by our department on February 1997 because of liver cell carcinoma. He was complicated with chronic subdural hematoma and became bedridden.
Colonoscopy was performed on disease day 22 because of sudden onset of indolent bloody stool. Geographic ulcer with an exposed blood vessel was detected in the lower portion of rectum. Because bleeding gradually increased in amount, despite our attempt at clipping, ethanol and HSE were locally injected on disease day 27. The same hemostatic treatment was performed on disease day 36 because of recurrence of bloody stool. Since then, no bloody stool had occurred, and the ulcer was colonoscopically confirmed to be cicatrized on disease day 72. Because it is rare to endoscopically observe a clinical course of ulcer until cicatrization, we herein report our case.
