A retrospective study on laparoscopic complete mesocolic excision via dorsal-medial hybrid approach for right colon cancer

Objective To investigate pathologic effects combined with postoperative results on right colon cancer with laparoscopic complete mesocolic excision(CME) via dorsal-medial hybrid approach compared with traditional medial approach. Methods A total of 68 patients with right colon cancer undergoing laparoscopic CME in our hospital between Ja-nuary and June 2017 were studied retrospectively. There were two groups including 37 cases in dorsal-medial hybrid group and 31 cases in traditional medial group. CME quality evaluated with the method proposed by West et al along with safety, short-term results and long-term prognosis were compared between two groups. Results CME completion rate was 86.5% in dorsal-medial hybrid group and 80.6% in traditional medial group without statistical difference(P=0.53). Laparoscopic dissection time in dorsal-medial group was significantly shorter than that in traditional medial group[(62.70±12.22) min vs.(70.39±11.98) min, P=0.01]. There was no statistical difference in operation time, blood loss, postoperative flatus time, postoperative complications and long-term prognosis of the patients between two groups. Conclusions Laparoscopic CME via dorsal-medial hybrid approach for right colon cancer could have less laparoscopic dissection time, and two approaches were similar in CME quality, safety and prognosis.
