ABSTRACT
PURPOSE:
This retrospective study was performed to investigate the recent trend of occurrence of cancer of the remnant colorectal segment(RCRS)after ileal-pouch anal anastomosis(IPAA)/ileorectal anastomosis(IRA)and to consider the optimal surveillance methods in patients with familial adenomatous polyposis(FAP)undergoing(procto)colectomy. PATIENTS ANDMETHODS:
The subject was a total of patients with FAP undergoing IPAA or IRA between 2005 and 2022. Clinicopathological data were extracted from medical charts and analyzed. Cumulative incidence of cancer in the RCRS and overall survival after treatment of such tumors were calculated by the Kaplan-Meier method.RESULTS:
There were 45 male and 56 female. IPAA was performed in 49 patients(hand-sewn; n=33, stapled; n=16)and IRA was performed in 52 patients. The median age at initial colorectal surgery was 32 years old(range, 13-66 years old). Median postoperative follow-up was 11 years(range, 1-48 years). Eighty-one patients were confirmed to have pathogenic variant of APC by genetic test. The cumulative incidence of cancer of the RCRS did not differ between patients undergoing IPAA and those undergoing IRA(p= 0.73, 4.1% versus 1.9% at 10 years). The cumulative 5-year overall survival rate after additional surgery for the tumor of RCRS was 82%.CONCLUSION:
This study has several limitations due to single institutional retrospective study with small cases and non-standardized postoperative endoscopic surveillance. However, our results seem to show satisfactory oncological outcomes of patients with FAP in terms of the control of cancer of the RCRS under postoperative periodic surveillance, regardless of the type of colorectal resection.
