Stoma retraction is most common in which ostomy type?

• A. With Crohn's disease
• B. With ileostomies
• C. With colostomies
• D. With urostomies

Answer: (B)

Stoma retraction is when the stoma sits below the skin level, making it hard to seal an ostomy appliance and increasing skin problems. This tends to be more common with ileostomies because the ileum is a small, highly mobile, thin-walled segment. When a stoma is created from the ileum, it often relies on a delicate balance of fixation to the abdominal wall. As edema resolves and healing progresses, the mobile ileal tissue can retract back into the abdomen if the stoma isn’t securely anchored to the fascia and abdominal wall or if there isn’t enough depth of protrusion. The colon, being thicker-walled and more fixed in place, generally provides more stable protrusion, so retraction happens less often with colostomies. Urostomies involve urinary diversion rather than a bowel segment, so their risk profile for stoma retraction is different, and Crohn’s disease affects tissue healing but isn’t the direct cause of retraction in this context.

So, the higher tendency for stoma retraction with ileostomies is linked to the mobility and pliability of the small bowel segment used, and the need for solid fixation to maintain protrusion through healing. If retraction occurs, revising stoma depth or using supportive measures can help restore a stable seal.
