Anastomotic Considerations in Crohn's Disease

Abstract

AbstractA number of factors should be considered when performing an intestinal anastomosis in the setting of surgery for Crohn's disease. Preoperative risk factors, such as malnutrition, abdominal sepsis, and immunosuppressive medications, may increase the risk of postoperative anastomotic complications and alter surgical decision-making. The anatomical configuration and technique of constructing the anastomosis may have an impact on postoperative function and risk of recurrence, particularly in the setting of ileocolic resection, where the Kono-S anastomosis has gained popularity in recent years. There may be circumstances in which it may be more appropriate to perform an ostomy either without an anastomosis or to temporarily divert an anastomosis when the risk of anastomotic complications is felt to be high. In the setting of total abdominal colectomy or proctocolectomy for Crohn's colitis, restorative procedures may appropriate in lieu of a permanent stoma in certain scenarios.
