Abstract
Colonic stenosis associated with ulcerative colitis without malignant tumor is very rare with only eight cases reported in Japan. A case of total colonic type of ulcerative colitis with severe stenosis of the transverse colon is reported. A 37-year-old man had been complaining of abdominal pain and diarrhea, and diagnosed as having ulcerative colitis since 1979. In 1998, he was admitted to the department because of vomiting and abdominal pain. Barium enema and colonoscopy revealed stenosis around the entire circumference of the transverse colon measuring about 10cm in length. Right hemicolectomy was performed because possible association of malignant tumor could not be ruled out. Histopathologically, inflammatory cells like polymorphonuclear leukocytes which infiltrated into mucosa and submucosa, hypertrophy of muscle layer, and fibrosis covering from submucosa to subserosa were observed. No malignancy was seen.
