Risk factors for complications after total colectomy in ulcerative colitis

Background/aims: Ulcerative colitis can be cured by total proctocolectomy. The aim of this study was to investigate the risk factors for colectomy-related complications in ulcerative colitis patients. Materials and Methods: All patients with ulcerative colitis who underwent total colectomy at Seoul National University Hospital from 1990 to 2009 were identified through a surgical database. Their demographic and clinical characteristics were reviewed retrospectively. They were followed for a mean of 6.2 years, and risk factors affecting the development of complications were analyzed. Results: A total of 85 ulcerative colitis patients (M:F = 35:50) were enrolled and analyzed. Eighty (94.1%) patients received total proctocolectomy with deal pouch-anal anastomosis. Thirty-nine (45.9%) patients had readmitted (95 hospitalizations) and 23 (27.1%) underwent further surgical procedures (44 operations) due to complications. Multivariate analysis showed that female gender (odds ratio [OR], 2.99; p=0.046), delayed surgery (OR, 3.45; p=0.03), and postoperative pathological diagnosis of dysplasia I cancer (OR, 4.22; p=0.03) were the risk factors for complication-related rehospitalization. Pouchitis (OR, 6.31; p=0.007) and frequent previous ulcerative colitis flare-up (OR, 1.39; p=0.023) were the risk factors for complication-related reoperation. Conclusions: Female gender, delayed surgery, pathological diagnosis of dysplasia 1 cancer, pouchitis, and frequent previous flare-up are the risk factors for postoperative complications.
