INTRODUCTION: The true incidence of Clostridioides difficile infection (CDI) in patients with an ileal pouch is unknown, and there is little published on its associated risk factors. OBJECTIVE: We aimed to evaluate the rate and risk factors of CDI in pouch patients. METHODS: This was a retrospective review conducted at a single tertiary care inflammatory bowel disease (IBD) center. All ulcerative colitis or IBD-unspecified (IBD-U) patients who underwent total proctocolectomy with ileal pouch anal anastomosis for medically refractory disease or dysplasia between 2008 and 2017 were identified. Symptomatic patients tested for CDI were included. Demographic, disease, and surgical characteristics were collected. Nonparametric methods were used to compare continuous outcomes, and χ2 and Fisher's exact tests were used to compare patients with and without CDI as appropriate. RESULTS: A total of 154 pouch patients had postoperative C. difficilestool testing for symptoms of fever, urgency, increased stool frequency, hematochezia, incontinence, and abdominal and/or pelvic pain. CDI was diagnosed in 11 (7.1%) patients a median of 139 days (IQR 34-1,170) after the final surgical stage. Ten patients (90.9%) received oral vancomycin for 10 days and 1 patient (9.1%) received oral metronidazole for 2 weeks. Ten patients (90.9%) reported improvement in symptoms at completion of therapy. Nine patients (81.8%) were retested for CDI for recurrent symptoms and found to be negative. No patient had CDI recurrence. There was no significant difference in demographic and surgical characteristics, previous antibiotic or proton pump inhibitor use, or previous hospital admission among the patients with and without CDI. CONCLUSIONS: CDI is a rare cause of infectious pouchitis and treatment with oral vancomycin improves symptoms.
