Background: Although Multiple studies showed that the median approach is nowadays the most widely accepted approach according to the "no-touch" principle and safety. However, this approach is a demanding procedure with a steep learning curve and has a high rate of conversion to laparotomy. This aim is to explore the feasibility and safety of tunnel approach in laparoscopic radical right hemicolectomy for colon cancer.Methods:From July 2016 to October 2018, a total of 106 consecutive patients

The patients underwent either tunnel approach (TA) (n=56) or traditional medial approach (MA) (n=50) according to the surgical maneuver performed. The patients' baseline demographics and perioperative results were compared between the two groups.Results: The baseline characteristics did not differ between groups. The blood loss was significantly less [20.0(5.0-40.0) vs. 100(50.0-150.0) , p < 0.001] and operation time was significantly shorter [128.4±16.7 vs. 145.6±20.3min, p < 0.001]in the TA group than those in MA group. Time to first flatus and postoperative hospital stay were similar [3.0(2.0-4.0) vs. 3.0(3-4.0)d,p=0.329; 10.4±2.6 vs. 10.7±3.0d,p=0.506] in both groups. The conversion to laparotomy and complication rates were similar between the groups(0 vs. 6.0%, p = 0.203; 14.3% vs. 18.0%, p =0.603,respectively). There was no treatment-related death in both groups.Conclusions: The tunnel approach in laparoscopic radical right hemicolectomy for colon cancer is a technically feasible and safe procedure as a preferable approach at present compared to those of medial approach, meanwhile this method is easier for beginners to master. Hence this tunnel approach right hemicolectomy is worth recommended.
