Abstract

Background Ulcerative colitis (UC) patients who undergo proctocolectomy with ileal pouch-anal anastomosis (IPAA) may develop pouchitis, a poorly understood inflammatory condition. There is controversy over whether tobacco use can protect against pouchitis. We undertook this investigation to further evaluate whether smoking reduces the risk of developing pouchitis and to determine whether other previously associated clinical factors change the risk for pouchitis. Methods We performed a retrospective analysis using a consented inflammatory bowel disease (IBD) natural history registry between the years 1995-2015 from a single tertiary care referral center. Demographic data, medical history, surgical information, medication use, laboratory data, and smoking history were abstracted. Former smokers had quit for at least 1 year. The primary end point was development of pouchitis. Results Of the 353 UC patients with IPAA in this study, 126 (35.6%) developed pouchitis. Prior tobacco use (P < 0.0001) was more common in patients who developed pouchitis. Former and active smokers were more likely to develop pouchitis compared with those without a history of tobacco use (63.4% vs 27.3% respectively, P < 0.001). There was no significant difference in active smoking rate between those without pouchitis and the group that did develop pouchitis. Multivariate analysis demonstrated that the only independent risk factor associated with pouchitis was a history of tobacco use. Conclusions These results suggest that smoking cessation may increase the likelihood of developing pouchitis in tobacco users with UC and IPAA, but active smoking does not seem to be more effective in preventing this condition.
