Abstract
AIM
Restorative proctocolectomy (RPC) is the most common operation for chronic ulcerative colitis (CUC), as it provides excellent functional outcome. However, among patients with Crohn's disease (CD), RPC is generally not recommended, as outcome and long-term function may be poor. Our purpose was to compare matched cohorts of CD and CUC patients to determine whether there are differences in outcome or function.
METHOD
We queried our prospectively maintained database of patients who underwent RPC from 1991 to 2008. We identified patients who underwent RPC for CD and compared them with a matched cohort of patients who underwent RPC for CUC.
RESULTS
We identified 13 patients with CD (seven women, median age 34 years) and 39 patients with CUC (21 women, median age 35 years). The patients were well matched for gender, clinical and demographic variables. Seven patients (54%) with CD had proctitis, but none had perianal or ileal disease. There were four (30.8%) postoperative complications and no anastomotic leaks. The CD group experienced significantly fewer median daily bowel movements (P = 0.02), incontinence for liquids (P < 0.01) and pouchitis (P < 0.01). With a median follow up of 44 months, pouch excision rate was significantly higher in the Crohn's group (2 vs 0%, P < 0.01).
CONCLUSION
In patients with CD, RPC may result in fewer daily bowel movements, less liquid incontinence and a lower incidence of pouchitis compared with CUC patients who undergo RPC. However, risk of pouch loss is higher in patients with CD. Therefore, in properly selected patients with CD, RPC provides an acceptable long-term functional outcome.
