Clinical Application of Preoperative Rectal Artery Embolization Combined with Laparoscopic Technology for Colorectal Cancer Resection

Abstract：Objective:To compare postoperative tumor recurrence and metastasis of colorectal cancer patients with preoperative rectal artery embolization combined with conventional laparoscopic or conventional laparotomy colorectal cancer resection,to analyze the clinical significance of rectal artery embolization combined with laparoscopic colorectal cancer resection.Method:80 cases with colorectal cancer in author’s department over the same period were randomly divided into four groups,group A(conventional laparotomy group),group B (conventional laparotomy combined with preoperative rectal artery embolization group),group C(conventional laparoscopic group) and group D(conventional laparoscopic combined with preoperative rectal artery embolization group).The CEA levels changes and liver imaging changes of four groups were compared.Result:The content of CEA during and after the operation between group A and group B,and between group C and group D,were statistically significant(P<0.05).B-ultrasound detection rate of liver after 12 months of operation between group A and group B,and between group C and group D,were statistically significant(P<0.05).Conclusion:Preoperative rectal artery embolization combined laparoscopic colorectal cancer resection can reduce the recent CEA concentration and the growth rate while achieved minimally invasive treatment,thereby reduces the blood supply to the tumor metastasis.
