This study aims to explore the safety, feasibility and short-term results of overlapped delta-shaped anastomosis in 3D totally laparoscopic right hemicolectomy.

From May 2017 to October 2018, a total of 32 and 35 patients who underwent overlapped delta-shaped anastomosis in 3D and 2D total laparoscopic right hemicolectomy were respectively selected. Data regarding surgical outcomes, postoperative recovery, pathological outcomes and complications were collected and compared.

Between the two groups, the operative time and anastomosis time of the 3D group were significantly less than those of the 2D group (all P<0.05), but there was no significant difference in intraoperative blood loss and length of incision (P>0.05). The time to ground activities, first flatus time, first defecation time and postoperative hospitalization did not differ between the two groups (all P>0.05). There was no significant difference between the two groups in tumor size, distance of proximal and distal incisional margins, number of lymph node dissection, TNM stage of the tumor, etc. (P>0.05). The incidence of postoperative complications in the two groups was 6.2% and 5.7%, respectively, with no significant difference (P=0.928).

3D totally laparoscopic right hemicolectomy with overlapped delta-shaped anastomosis is a safe and feasible procedure with a satisfactory short-term effect. Compared with 2D laparoscopic surgery, 3D laparoscopy can shorten the operation time and anastomosis time significantly.
