Compromised visceral circulation does not affect the outcome of colorectal surgery

Anastomotic leakage is a serious complication after colorectal surgery, and many risk factors for this problem have so far been identified. The aim of this study was to assess the association between visceral arterial occlusive disease and anastomotic leakage.

The preoperative abdominal computed tomography scans from all consecutive patients who underwent colorectal surgery with anastomosis in 2010 were retrospectively analyzed.

A total of 242 patients were included, with a median age of 65 years (interquartile range 55-74). Anastomotic leakage occurred in 14 % of cases (n = 34). The mortality rate was 3 % (n = 8). There was no association between atherosclerosis of the visceral or iliac arteries and anastomotic leakage. There was also no association between right-sided or left-sided resections and total occlusion of the superior or inferior mesenteric artery, respectively.

Asymptomatic visceral artery occlusive disease is not a risk factor for anastomotic leakage after colorectal surgery, and additional radiological imaging or percutaneous transluminal angioplasty for occluded visceral vessels is not indicated prior to colorectal surgery.
