BackgroundThe rate of restoration of intestinal continuity after colonic resection and stoma creation in patients with Crohn's disease has not been well-documented in the era of biologics. Thus, the incidence of restoration of intestinal continuity since the introduction of biological drugs was assessed.MethodsConsecutive patients (n = 43) who underwent colonic resection with ileostomy or colostomy formation for Crohn's disease at a single tertiary referral center between 2002 and 2014 were identified. Data from individual chart review were analyzed retrospectively. Patients were personally contacted for follow-up.ResultsOf the 43 patients 8 (18.4%) had a proctectomy leaving 35 patients (81.4%) with the rectum preserved. Of the 30 patients qualifying for final analysis restoration of bowel continuity was finally achieved in 10 patients (33.3%). Permanent stoma rates were comparable in the group of patients with and without biological therapy after surgery (64.3% vs. 60%). The median follow-up period was 7 years (range 3-15 years). Of the patients 20 suffered from perianal disease involvement (66.7%), which was associated with a higher rate of permanent stoma (n = 16/20, 80%) in contrast to patients without perianal disease (n = 4/10, 40%, p = 0.045).ConclusionThe overall incidence of stoma formation was low for patients with Crohn's disease; however, once a stoma is created the chance of ending up with a permanent stoma is high even in the era of biologics. Despite the use of new therapeutic agents perianal disease increases the risk of a permanent stoma.
