Objective:
Anastomotic leakage (AL) is a catastrophic surgical complication affecting the prognosis of patients after colorectal surgery. We aimed to determine the value of the arterial calcification (AC) score in predicting AL.
Methods:
Medline and Embase were searched through November 2019. The odds ratio (OR) and 95% confidence interval (CI) were used to estimate the association between AC and AL after colorectal surgery. The fixed-effects model or random-effects model was adopted for data pooling. Subgroup analyses were conducted to assess the effect of different aortoiliac trajectories.
Results:
Four studies involving 496 patients were included. The calcium volume and calcium score measurements of different trajectories revealed a significant difference with regard to the left and right common iliac arteries, the superior mesenteric artery, and the left common iliac artery. Calcification of the internal iliac artery significantly increased the risk of AL compared with no AL (OR = 1.005; 95% CI 1.002-1.009; P = 0.005), as did calcification of the left internal iliac artery (OR = 1.009; 95% CI 1.002-1.016; P = 0.011), but not of the common iliac artery (OR = 1.001; 95% CI 1.000-1.001; P = 0.317) or common and internal iliac artery (OR = 1.000; 95% CI 1.000-1.000; P = 1.000).
Conclusions:
AC is associated with increased risk of AL following colorectal surgery.
