Research status and prospects of digestive tract reconstruction after laparoscopic right hemicolectomy of colon cancer / 中华消化外科杂志

ABSTRACT

Intracorporeal anastomosis in laparoscopic right hemicolectomy of colon cancer is becoming a hot spot in colorectal surgery. A number of retrospective studies have suggested that intracorporeal anastomosis has potential advantages in promoting postoperative recovery and reducing postoperative complications compared with conventional extracorporeal anastomosis. Several randomized controlled trials published recently have also confirmed that intracorporeal anastomosis can promote postoperative gastrointestinal function recovery and reduce postoperative pain, but there is still insufficient evidence to draw a conclusion about the incidence of complications, especially the anastomotic leakage rate. Heterogeneity of surgical techniques and unclear definition of anastomotic leakage are the main difficulties in current studies. Several high-quality prospective randomized controlled trials are currently under way, and high level of evidence is needed to objectively evaluate the laparoscopic right hemicolectomy of colon cancer. The authors review the relevant literatures at home and abroad, systematically elaborate the research status and prospects of digestive tract reconstruction after laparoscopic right hemicolectomy of colon cancer, in order to explore a new direction for the clinical research of colorectal surgery in China.
