The American Gastroenterological Association (AGA) has released the first comprehensive evidence-based guideline on the management of pouchitis, the most common complication people with ulcerative colitis experience following surgery to remove their colon. The guideline has been published in the journal Gastroenterology.

Between 150,000 and 300,000 people with ulcerative colitis in the U.S. live with a surgically created internal reservoir or "pouch" created from their small intestine as an alternate way to store and pass stool after their diseased colon is removed. The pouch can become inflamed, a condition called pouchitis, which affects almost half of patients within two years of surgery and up to 80% of patients over time.

"As providers we struggle to get insurance approval for medications to treat pouchitis, because it has not been a well-defined or recognized entity. Our intention with this guideline is to help improve access for patients and providers to use these advanced therapies," said guideline author Siddharth Singh, MD, MS, University of California, San Diego.

AGA provides the following guidance for physicians caring for patients with ulcerative colitis who undergo proctocolectomy with ileal pouch-anal anastomosis, also known as IPAA or J-pouch:

  • AGA suggests initial treatment of pouchitis with antibiotics.

  • Treatment with multi-strain probiotics following an antibiotic course is suggested for preventing recurrent pouchitis.

  • AGA suggests cyclical or near continuous antibiotic therapy to treat pouchitis that responds to antibiotics but recurs frequently and shortly after antibiotics are discontinued.

  • In patients with recurrent pouchitis that doesn't respond to antibiotics or Crohn's-like disease of the pouch, AGA suggests advanced immunosuppressive medications (ie. Infliximab, vedolizumab, ustekinumab, upadacitinib, etc.)

Pouchitis has a significant impact on patients' quality of life, so there is interest in ways to prevent it from occurring. The AGA guideline suggests against use of antibiotics for primary prevention of pouchitis, and guideline authors did not find enough scientific evidence to recommend for or against the use of probiotics for prevention.

AGA outlines four types of inflammatory pouch disorders

1) Intermittent pouchitis: This happens when a patient experiences infrequent episodes of pouchitis symptoms that get better with treatment.

2) Chronic antibiotic-dependent pouchitis: This occurs when a patient's pouchitis responds to antibiotics, but symptoms quickly return after antibiotics are stopped (typically within days to weeks).

3) Chronic antibiotic-refractory pouchitis: This occurs when patients experience continuous symptoms of pouchitis that don't get better with antibiotic therapy. Patients usually require more advanced treatment such as steroids or immunosuppressive medication.

4) Crohn's-like disease of the pouch: Patients may have issues like fistulas (abnormal passages), strictures (narrowing) and inflammation in the small intestine above the pouch.

Amber Tresca, a patient advocate who has been living with a J-pouch for over 20 years shares that, "it's important for patients to know how to care for their pouch if they develop pouchitis, especially if they don't have access to a health care provider that is a pouch specialist. This guideline can help patients understand that pouchitis is a real condition, there is treatment for it, and that they don't have to live with symptoms."
