ANISAKIASIS OF THE COLON ; REPORT OF A CASE OBSERVED COLONOSCOPICALLY

Abstract

A 38-year-old male visited our clinic because of his abdominal pain and dirrhea. Clinical examination revealed leukocytosis. Because of his history of having Shimesaba (vinegared mackeral) in the previous evening, anisakiasis of the stomach was suspected. However, upper G-I endoscopy revealed no remarkable lesions. Colonoscopy showed a reddish edematous lesion in the transverse colon. In the center of the lesion, a worm was observed to thrust into the colonic wall. It was removed by using a biopsy forceps. After the procedure the symptom disappeared rapidly.
