Anastomosis after Bowel Resection for Crohn's Disease: State of the Art Review

Abstract

AbstractRecurrence after surgically induced remission in Crohn's disease remains a topic of research and debate with significant clinical implications for overall quality of life and intestinal and defecatory functions. While the surgeon continues to play a critical role in surgical prophylaxis of recurrence, optimal results will only be obtained in the setting of a true multidisciplinary team approach, following the principles of “the right surgery, on the right patient, at the right time, performed by the right surgeon, supported by the right team.” The centerpiece of surgical prophylaxis is the intestinal anastomosis. The ideal anastomosis after resection for Crohn's disease should be safe and reliable, as postoperative septic complications have been shown to increase the risk of recurrence; result in a wide lumen and a configuration that would not impede enteric flow; exclude or excise the mesentery, a known culprit in primary and recurrent disease; and preserve vascularization and innervation. This article will review the evidence supporting the above-mentioned surgical principles and the long-term results of the different anastomotic configurations.
