Anisakiasis of the Colon: Report of Two Cases

Anisakiasis is a rare finding in the colon in comparison with its involvement in the stomach. Also, anisakiasis of the colon is usually incidentally diagnosed during either endoscopy or on operation for intestinal obstruction due to the fact that anisakiasis of the colon does not have typical clinical features. In other words, the diagnosis of colonic anisakiasis is usually made after surgical exploration. We herein report on two cases of anisakiasis of the colon that were treated successfully by colonoscopic removal of the worm without any surgery. A review of the related literature is included.
