Mesenteric Artery Stenosis is a Risk Factor for Anastomotic Leakage in Colorectal Surgery.

Objective: Anastomotic leakage (AL) after colorectal surgery leads to substantial morbidity and mortality. Theoretically, compromised blood flow caused by mesenteric artery (MA) stenosis may create suboptimal healing conditions at the anastomotic site, increasing susceptibility to AL. The association between MA stenosis on pre-operative computed tomography (CT) scans and AL in patients undergoing colorectal surgery was investigated.
