Obstructive Colitis Proximal to Obstructive Lesion of the Colon Cancer / 대한소화기내시경학회지

ABSTRACT

Obstructive colitis is a rare inflammatory condition that occurs in a dilated segment of the colon proximal to an obstructing lesion. A 69-year-old patient presented with abdominal pain and distension. The colonoscopy findings revealed a near total obstruction from sigmoid colon cancer. The mucosa of the obstructive lesion was erythematous and hemorrhagic but normal mucosa was found immediately above the 3 cm long obstructive lesion. The proximal bowel of the normal mucosa showed colitis with hemorrhagic mucosal changes and yellowish exudative plaques. Surgery was performed as a segmental resection after placing a metallic stent to decompress the proximal colonic loop. In conclusion, obstructive colitis should be considered if an ulcero-inflammatory lesion with a colonic obstruction and a skip lesion in the proximal colon are detected.
