Why This Matters

Someone with Crohn’s disease and limited remaining small intestine may face high-risk surgical choices. This case report suggests a specialized oral supplement used with conservative care was associated with fistula closure and avoidance of further resection in one patient.

Who Should Pay Attention

Patients with Crohn’s disease who have post-surgical fistula, short-bowel risk, caregivers, and clinicians managing complex postoperative IBD cases.

What To Know

This case report describes a 39-year-old woman with long-standing Crohn’s disease and a short remaining small intestine who developed an enteric fistula after suture failure following abdominal surgery.

Instead of resection (which risked worsening short-bowel syndrome), clinicians used conservative management that included continuous aspiration and an oral nutritional supplement containing CaHMB, L-arginine, and L-glutamine (Abound™).

The report states that granulation increased, the fistula narrowed, drainage stopped after 13 days on the supplement, oral intake resumed on day 16, discharge on day 22, and wound healing by day 36. The article is a single case report, not a trial.

It suggests a possible role for an oral specialized nutritional supplement combined with conservative care in promoting fistula closure in a patient where surgery posed high risk. This is preliminary and cannot establish cause-and-effect.

If you have Crohn’s-related surgical complications or short bowel concerns, discuss any supplement use and surgical vs conservative plans with your gastroenterologist or surgical team before making changes.

Keep In Mind

Single-case report only; cannot prove the supplement caused healing. Discuss supplements and treatment plans with treating clinicians before use.
