Abstract：Objective To study the value of abdominal spiral CT angiography (CTA) and three-dimensional imaging of colon before laparoscopic radicalesection of colon cancer. Methods The clinical data of eighty colon cancer patients from September 2017 to February 2019 was collected. According to preoperative examination, patients were divided into two groups: the combined imaging group and the conventional CT group,there were 40 patients in each group. The baseline data, intraoperative and postoperative related indexes were compared.The value of combined imagingof tumor were also analyzed. Results In the combined imaging group, the intraoperative blood loss (137.34±59.68) ml was less than that in the routine CT group (181.75±53.42) ml (P=0.001), the operation time (165.90±47.85) min was shorter than that in the conventional CT group (192.88±43.16) min (P=0.010), and the total postoperative abdominal drainage (61.03±18.82) ml was less than that in the routine CT group (73.10±21.16) ml (P=0.009). CTA combined with three-dimensional fusion images can directly display the panoramic images of various tissues and organs, colon tumors and their blood vessels. Conclusions Preoperative abdominal CTA and three-dimensional imaging of the colon have certain advantages, as this method can identify the anatomical location of the colon tumor and its blood supply vessels, and also can effectively shorten the operation time and reduce the amount of intraoperative bleeding. In addition, it may be more helpful to young and unskilled doctors.
