Segmental resection is a safe oncological alternative to total proctocolectomy in elderly patients with ulcerative colitis and malignancy.
COLORECTAL DISEASE(2017)
摘要
AimThe standard approach for the surgical management of colorectal cancer (CRC) in the setting of ulcerative colitis (UC) involves total proctocolectomy (TPC). However, some patients also undergo a partial resection (PR). This may be an attractive option in older patients with a high risk for surgery. The aim of this study was to compare the risk of metachronous cancer after PR or TPC for CRC in the setting of UC. MethodThis was a retrospective cohort study conducted through the Nationwide Veterans Affairs Healthcare System (VA). Patients who had UC and underwent a PR or TPC for CRC were followed from the time of their surgery to their most recent clinical follow-up. The primary outcome was development of metachronous cancer in the PR group. Secondary outcomes included surgical and medical outcomes. ResultsFifty-nine patients were included: 24 (40.7%) underwent PR and 35 (59.3%) underwent TPC. The median age at cancer diagnosis was 73.0 and 61.7years in PR and TPC groups, respectively (P<0.0005). Amongst patients undergoing PR, 15 (60%) had no active UC at the time of surgery, whereas in patients undergoing TPC, at the time of surgery eight (23.5%) had no active UC (P=0.005). No patient who underwent a partial colectomy developed a metachronous cancer in the retained colonic segment during the follow-up period (median 7years). ConclusionOur study suggests that PR for CRC in the setting of UC may be a viable option in a selected cohort of patients, especially among the elderly.
