Purpose: Restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) for ulcerative colitis is associated with pouch-related septic complications (PRSC) in 10% of patients. This study questioned if PRSC have a negative impact on pouch function and quality of life.
Patients and methods: One hundred thirty consecutive patients undergoing IPAA for ulcerative colitis between 1997 and 2009 were reviewed. At 1-year follow-up, patients were asked to complete questionnaires including a pouch function score (Oresland score, 0-16 points, 0 optimum) and two quality of life scores [Short Inflammatory Bowel Disease Questionnaire (SIBDQ), 1-7 points, 7 optimum; Gastrointestinal Quality of Life Index (GIQLI), 0-144 points, 144 optimum].
Results: Twelve out of 130 patients (9.2%) undergoing IPAA developed PRSC. These included anastomotic dehiscence (five), pouch leakage (three, one patient had a combined leak), peripouchal abscess (three), pouch-anal fistula (one), and pouch-vaginal fistula (one). Omission of diverting ileostomy was a risk factor for PRSC (OR 4.62, CI 1.17-18.4). PRSC led to four pouch failures (33%), whereas no failure occurred in the control group (p < 0.001). Median 3 (range, 1-10) further operations were necessary until the pouch was salvaged or definitively lost. If the pouch was salvaged, functional Oresland score (8.2 ± 1.3 vs. 6.6 ± 0.5; p = 0.127), SIBDQ (5.0 ± 0.5 vs. 5.5 ± 0.1; p = 0.203), and GIQLI (95.8 ± 8.4 vs. 107.3 ± 2.6; p = 0.119) were not significantly inferior to uncomplicated controls.
Conclusions: In case of PRSC, even multiple surgical approaches are worthwhile as the outcome of salvaged pouches in terms of function and quality of life is not substantially inferior to patients without septic complications.
