Comparison of Two Stapled Antimesenteric Anastomosis for CD: a Randomized Control Trial Study

The postoperative recurrence of Crohn's diseases (CD) remains high. Stapled anti-mesenteric functional end-to-end anastomosis was safe for CD patients. Its impact on the postoperative recurrence of CD was unknown. Whether it is superior than the conventional anastomosis (stapled antimesenteric isoperistaltic side-to-side anastomosis) needs explored. The trial aims to compare the different impacts of the two antimesenteric anastomosis configurations on the anastomotic recurrence following bowel resection.

Inclusion Criteria:patients with Crohn's disease needing bowel resection and anastomosis;ileocolic anastomosis；written consent acquiredExclusion Criteria:patients underwent enterostomy;small bowel anastomosis;anticipating other trial.
