Abstract:
PEG tubes are used for decompression of the stomach or enteral feeding and are secured with bumpers. These bumpers may migrate. A patient with a stenotic ileostomy stoma is presented in whom migration of a PEG tube bumper resulted in an intermittent small bowel obstruction. Revision of the ileostomy stoma with removal of the bumper resolved the problem. Bumper migration should be considered a possible etiology for bowel obstruction in patients with PEG tubes especially if they have a stenotic stoma.

Ostomy Care
An ostomy is a surgical procedure that creates an artificial opening from the intestines to the outside of the body, allowing for the rerouting of effluent. This opening is known as a stoma. A stoma usually protrudes above the skin surface, appearing pink or red, moist, and round, and it lacks nerve sensations.
There are different types of ostomies, including colostomies, ileostomies, and urostomies:
