Peristomal hernias are most commonly seen with which ostomy, and in what timeframe after surgery?

• A. All ostomies equally; anytime after surgery
• B. Colostomies; in the first two years after surgery
• C. Ileostomies; within two years
• D. Urostomies; within six months

Answer: (B)

Parastomal hernias happen when the tissue around the stoma becomes weak and abdominal contents protrude beside the stoma. The risk is greatest with colostomies because the fascial opening created for a colostomy is typically larger and the surrounding tissues have to support a substantial load early in healing. This makes the first two years after surgery the most vulnerable period, as the abdominal wall and stoma tract are still remodeling and gaining strength. After this window, new hernias are less likely, though they can still occur.

That’s why the best choice is that colostomies have the highest occurrence, most often within two years after the operation. Other ostomy types can have parastomal hernias, but they are less common, and the typical high-risk timeframe is not as clearly within six months or within two years for those options.
