A CASE OF ABSCESS OF THE TRANSVERSE COLON TREATED BY ENDOSCOPIC DRAINAGE

Abstract

A 59-year-old woman visited to our hospital because of right lower abdominal pain. The computed tomography (CT) findings ; localized thickening of the colonic wall and increased density in the pericolic fat around the hepatic flexure were compatible with pericolic abscess. Colonoscopy revealed a smooth hemispherical protrusion covered with normal mucosa on the anal side of the hepatic flexure and then drainage of pus into the colonic lumen was observed from the top of the lesion at biopsy. Her symptoms were almost disappeared day after colonoscopy and the CT findings one month later were ameliorated without admission. Colonoscopic intraluminal drainage would be useful for the treatment of pericolic abscess.
