Abstract: Laparoscopic surgery has been accepted as an optimal treatment for colon cancer. Digestive tract reconstruction may be performed using extracorporeal anastomosis or intracor-poreal anastomosis after radical colectomy of colon cancer. More and more studies have compared both procedures, but the selection of optimal method of digestive tract reconstruction is still controversial. The authors conduct a systematic review on the application and research advances of intracorporeal anastomosis in laparoscopic surgery for colon cancer, investigate the technical skills of intracorporeal anastomosis and its clinical outcomes, so as to provide valid information for its clinical application.
