Abstract: Objective To evaluate the feasibility and safety of improved delta-shaped anastomosis in the process of laparoscopic right hemicolectomy for digestive tract reconstruction in patients with colon cancer. Methods From January 2013 to December 2016，one hundred and thirty-five patients were treated with laparoscopic right hemicolectomy and improved delta-shaped anastomosis，and the data of these patients were collected and analyzed to assess the value of this technique. Results One hundred and thirty-five patients were all successfully performed by laparoscopic right hemicolectomy and improved delta-shaped anastomosis. The median operation time was 140 minutes. The median blood loss was 50 ml. The median time from surgery to first flatus was 2 days and the median time from surgery to discharge was 10 days. There were no anastomotic related complications such as leakage，hemorrhage and stenosis. Conclusion Improved delta-shaped anastomosis is a safe and reliable technique for ileocolostomy and appeared to be an ideal method of digestive tract reconstruction for laparoscopic right hemicolectomy.
