Application of Laparoscopic Complete Mesocolic Excision in Radical Resection for Right Colon Cancer / 中国微创外科杂志

ABSTRACT

Objective To evaluate the safety of laparoscopic complete mesocolic excision (CME) in radical resection for right colon cancer. Methods From January 2012 to June 2013, laparoscopic CME was performed in 40 patients with right colon cancer. Another group of 38 patients underwent traditional radical resection from January 2011 to December 2011.Surgical outcomes were compared between the two groups . Results The number of lymph nodes retrieved in the laparoscopic group ( 22.1 ±7.8 ) was significantly more than that in the traditional group (18.6 ±4.3, t =2.436, P =0.017).In patients with stage Ⅲ cancer, the laparoscopic group was associated with higher lymph node counts (23.0 ±6.0 vs.18.2 ±5.1, t=2.699, P=0.000), however, there were no significant differences in those with stage Ⅱ cancer between the two groups (t=0.758, P=0.454).There were no differences in operation time and intraoperative blood loss between the two groups (t=0.716, P=0.476;t=-1.547, P=0.126), but in the laparoscopic group the time to pelvic drainage tube removal , time to first flatus, time to liquid diet intake , duration of hospital stay, and postoperative complications were significantly better than those in the traditional group (t=-2.950, P=0.004;t=-5.767, P=0.000; t =-7.817, P =0.000; t =-6.065, P =0.000; χ2 =4.504, P =0.034). Conclusions CME technique in laparoscopic radical right hemicolectomy is feasible , safe, and effective.CME improves the surgical quality with keeping the integrity of mesocolon , more harvested lymph nodes , and not increasing surgical risks and postoperative complications .
