Laparoscopic right colectomy is considered to be the standard treatment of colon cancer,the digestive tract reconstruction after resection divides into extracorporeal ileocolic anastomosis(EIA)and intracorporeal anastomosis ileocolic anastomosis(ⅡA);EIA is simple to perform,whiles the ⅡA is performed in the abdominal cavity,which leads to fast intestinal function recovery and small incision.However,ⅡA is time-consuming and difficult in technically,which limit the widespread use,and it is not clear whether intraperitoneal anastomosis increases the incidence of postoperative intra-abdominal infection and anastomotic leakage.Therefore,the choice of reconstruction is still controversial.This article will describe the methods and clinical results of digestive tract reconstruction after laparoscopic right colectomy,in order to provide more references for clinicians.
