OBJECTIVE: To explore the feasibilities between operational approaches for laparoscopic complete mesocolic excision (CME) to right hemicolon cancer. METHODS: This prospective randomized controlled trial included patients admitted to a Shanghai minimally invasive surgical center to receive laparoscopic CME from September 2011 to January 2013 randomized into two groups: hybrid medial approach (HMA) and completely medial approach (CMA). The feasibilities and strategies of the two techniques were studied and compared. Furthermore, the operation time and vessel-related complications were designed to be the primary end points, and other operational findings, including the classification of the surgical plane and postoperative recovery, were designed to be the secondary end points for this study. RESULTS: After screening, 50 cases were allocated to the HMA group and 49 to the CMA group. Within the HMA group, there were 48 cases graded with mesocolic plane and 2 with intramesocolic plane. For the CMA group, there were 42 cases graded with mesocolic plane and seven with intramesocolic plane. The differences between the two were insignificant, as were the number of lymph nodes retrieved. The mean±standard deviation total operation time for the CMA group was 128.3 ± 36.4 min, which was significantly shorter than that for the HMA group, 142.6 ± 34.8 min. For the CMA group, the time involved in central vessel ligations and laparoscopic procedures was 58.5 %, 14.1 and 81.2 ± 23.5 min, respectively, which were shorter than the HMA group. The vessel-related complication rate was significantly higher in the HMA group. CONCLUSIONS:Laparoscopic CME via the total medial approach is technically feasible after the precise identification of the surgical planes and spaces for the right hemicolon. The procedure has a shorter operation time and fewer vessel-related complications.
