To investigate the safety and feasibility of laparoscopic complete mesocolic excision and radical right hemicolectomy via caudal lateral approach.

The clinical data of 21 patients with right hemi-colon cancer who underwent laparoscopic complete mesocolic excision via caudal lateral approach from Jan. 2019 to Dec. 2019 were retrospectively analyzed.

All the 21 operations were completed successfully without conversion to laparotomy.The average operation time was (150.4±28.1)min, and the average blood loss was (78.57±190.76)mL, the mean number of lymph nodes harvested was (18.5±5.4), the extubation time of postoperative catheter(4.0±0.9)d, the mean time of first flatus was (3.0±0.6) d,the mean time of liquid oral intake was (3.5±2.6)d, the average hospital stay was (7.2±2.5)d after operation. The incidence of postoperative complications was 14.28%(3/21), including one anastomotic bleeding, one diarrhea, one pulmonary infection with intestinal obstruction, and they were all cured with conservative treatments. The pathological results of all patients were 10 adenocarcinoma, one mucinous adenocarcinoma, seven canalicular adenoma, three adenocarcinoma with mucinous adenocarcinoma. The postoperative tumor staging: The tumor stages included stage Ⅰ in 1 patients, stage ⅡA in 8 patients, stage ⅢA in 1 patients, and stage ⅢB in 11 patients. There was no death during perioperative period.

It is safe and feasible to adopt the caudal lateral approach to laparoscopic right hemicolon cancer radical operation, which is in accordance with the principle of CME and worthy of clinical promotion.
