To investigate the efficacy and safety of 3D laparoscopic, 2D laparoscopic and open laparoscopic complete mesorectal excision (CME) in the treatment of stage III elderly right colon cancer.

Retrospective analysis of 90 elderly patients with right colon cancer from January 2013 to January 2017 was divided into three groups according to different surgical methods, namely 3D group, 2D group and open group, 30 cases in each group. The data were analyzed by SPSS21.0 software. The indexes of the surgical conditions and the level of tumor markers were described by (±s) and analyzed by independent t test. Postoperative complications were described by (n, %) and analyzed by χ² test. The difference was statistically significant at P<0.05.

The operation time of the 3D laparoscopic group was significantly higher than that of the open group (P<0.05), The intraoperative blood loss and hospital stay were significantly lower than the open group (P<0.05), there was no significant difference between the patients in the 2D laparoscopic group (P>0.05); The number of lymphatic dissection and dietary fluid diet in the 3D laparoscopic group were significantly better than the other two groups (P<0.05); However, the anal recovery ventilation time and defecation time of the 3D laparoscopic group were not significantly different from the other two groups (P>0.05); The total incidence of postoperative complications in the three groups was significantly different (P<0.05), and the total incidence of postoperative complications was the lowest in the 3D laparoscopic group; On the 8th day after surgery, the levels of CA-125, CA19-9, and CEA in the three groups were significantly lower than those before surgery, the levels of CA-125, CA19-9, and CEA in the 3D laparoscopic group were significantly lower than the other two groups (P<0.05).

3D laparoscopic CME surgery is safe and feasible for the treatment of stage III elderly right colon cancer. The clinical effect is remarkable, the surgical field is clear, and the visual effect is three-dimensional. It is worthy of further application and promotion.
