What are possible complications from an ileoanal anastomosis?

An ileoanal anastomosis is a surgical procedure that connects the end of the small intestine (ileum) to the anal canal. This procedure is typically performed to treat conditions such as ulcerative colitis and Crohn's disease. While it is generally a safe and effective procedure, there are some potential complications that can occur. Some of the possible complications of an ileoanal anastomosis include:

Leakage from the anastomosis: This is one of the most common complications and can occur in up to 10% of cases. Leakage can lead to infection, sepsis, and prolonged hospitalization.

Stricture (narrowing) of the anastomosis: This can occur in up to 5% of cases and can cause difficulty with bowel movements. Strictures may require dilation or surgery to correct.

Incontinence: This can occur in up to 10% of cases and can range from mild to severe. Incontinence can be managed with medication, diet, and lifestyle changes.

Pouchitis: This is inflammation of the ileal pouch and can occur in up to 20% of cases. Pouchitis can be treated with medication and dietary changes.

Sexual dysfunction: Some patients may experience difficulty with sexual function following an ileoanal anastomosis. This can be due to damage to nerves or muscles during surgery.

Other complications: Other potential complications include bleeding, infection, blood clots, and the development of fistulas. These complications are relatively rare but can be serious.

It is important to discuss the potential risks and complications of an ileoanal anastomosis with a doctor before undergoing the procedure.
