Ileocolonic End-to-End Anastomoses in Crohn's Disease Increase the Risk of Early Post-operative Endoscopic Recurrence in Those Undergoing an Emergency Resection.

Background And Aim: Several risk factors affecting post-operative recurrence in Crohn's disease patients have been studied, and of these, the role of the anastomosis remains contentious. We aimed to compare the risk of developing early post-operative endoscopic recurrence (EPER), in resections that had an end-to-end anastomosis (ETEA) to a side-to-side anastomosis (STSA).

Methods: All Crohn's disease patients that underwent an ileocolic or small bowel resection between January 2012 and June 2017 at two tertiary IBD centres were reviewed retrospectively.
