Peristomal fistulas are most commonly observed in patients with which conditions?

• A. Ileostomies or inflammatory bowel disease.
• B. Only urostomies.
• C. All ostomies equally.
• D. Occur only with improper technique.

Answer: (A)

Peristomal fistulas occur when an abnormal tract forms around the stoma, usually due to disease processes in the bowel near the stoma. They are most commonly seen in ileostomies and in inflammatory bowel disease because these conditions—especially Crohn’s disease—can involve fistulizing inflammation that creates additional tracts from the bowel to the skin or to adjacent loops. Urinary diversions like urostomies don’t inherently carry the same risk for intestinal fistula formation, and the problem isn’t simply due to technique. So, the combination of ileostomy with inflammatory bowel disease represents the situation with the highest likelihood of developing a peristomal fistula.
