Abstract OBJECTIVE: To evaluate the quality of life with emphasis on bowel function in patients undergoing either total colectomy with ileorectal anastomosis (IRA) or restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) for familial adenomatous polyposis (FAP). PATIENTS AND METHODS: All 151 patients operated on in our department between 1971 and 2000 were analysed retrospectively. Since 42 patients had to undergo reoperations, a total of 194 bowel procedures were performed. The final operative breakdown was: 48 IRA, 62 IPAA, 33 total proctocolectomies and 8 other procedures. By the end of the period under consideration, 40 patients had died, 28 had been lost to follow-up, 83 patients were still alive and of these 76 were analysed. Continence function and quality of life with emphasis on overall bowel function (Wexner (WS)-, Jostarndt (JS)-, Oresland (OS)- and Pemberton (PS)-scores) were recorded in 59 patients (22 IRA and 37 IAP). RESULTS: Continence and bowel function were significantly better after IRA than after IPAA (mean scores: WS, 1.1 vs 5.4, P=0.001; JS, 32.5 vs 24.7, P=0.0001; OS, 2.9 vs 7.9, P=0.0001), as was quality of life (PS, 25.6 vs 19.6, P=0.001). The mean values for each single item of all 4 scores were consistently better after IRA. Neither gender, age nor type of pouch-anal anastomosis (stapled vs hand-sewn) had a significant influence on outcome. IPAA patients with uneventful follow-up (n = 27) had better mean values for all 4 scores (WS, 4.2 vs 7.3; JS, 26.1 vs 23.1; PS, 20.4 vs 17.7; OS, 6.6 vs 9.9) than those with postoperative complications (n = 10; 27\%), but statistical significance was reached only in the OS (P = 0.026). No such difference was seen after IRA (14\% complication rate). CONCLUSION: The significantly better continence after IRA resulting in superior patient comfort and quality of life must be balanced against the oncological disadvantage of this procedure. On the basis of large patient population studies, genotype-phenotype correlations with respect to the risk for rectal cancer may need to be taken into account. Postoperative complications may have a lasting negative effect on outcome after IPAA.
