Pouchy.orgBowel Obstruction Risk
Why obstructions can happen after pouch surgery and what to do.
What Is a Bowel Obstruction?
A bowel obstruction is a blockage that prevents stool and fluid from passing through the small intestine. It can be caused by scar tissue (adhesions) from prior surgery, swelling, a hernia, or sometimes by undigested food sitting at a tight spot.
Why It Can Happen After Pouch Surgery
Any abdominal surgery can lead to scar tissue forming inside the abdomen. This scar tissue is normal but occasionally creates bands that can kink or compress the bowel. The risk is highest in the first months and years after surgery, but it can also happen years later.
Warning Signs
- No stool or gas passing for more than half a day to a day
- Bloating and abdominal cramping that comes in waves
- Nausea and vomiting (especially if you can’t keep fluids down)
- Inability to take in or keep down food or liquids
- Distended, tight abdomen
What to Do
If you suspect a bowel obstruction, contact your surgical team or go to the emergency room. Many obstructions improve with bowel rest, IV fluids, and time — a hospital stay may be needed. A smaller number require surgery to release the blockage. Acting early gives the best chance of avoiding surgery.
Reducing Your Risk
- Chew thoroughly and eat small, frequent meals
- Be cautious with high-fiber, fibrous, or stringy foods (popcorn, raw vegetables, nuts, certain fruit skins)
- Stay well-hydrated
- Pay attention to early warning signs and call your team rather than waiting
