| Popis: | A 66-year-old-man had received colonoscopy periodically as a follow up since endoscopic polypectomy of the colon in February 1997. In March 2001, periodic colonoscopy revealed a worm penetrating the mucosa of the sigmoid colon. This worm was caught with biopsy forceps, and it was identified parasitologically as an Anisakis simplex larva (Anisakis larva type I). However, the patient had no complaint before or after the examination. The patient ingested lavage solution, including polyethylene glycol for the preparation of colonoscopy. Therefore, Anisakis larvae might be flushed quickly to the distal colon by an oral colon-wash without penetration of worms into the gastric or intestinal mucosa. In the present paper, we report on asymptomatic colonic anisakiasis treated successfully by endoscopic removal of the worm. In some cases, penetration of the worm causes cramp of the colon or immediate mucosal huge edematous change and results in intestinal obstruction. Colonoscopic removal of the worm would be most effective and safe if possible. |
