Abstract:

Objective To study the short-term outcomes of laparoscopic right hemicolectomy with transvaginal specimen extraction without abdominal incisions(CRC-NOSES Ⅷ A) for radical resection of colon cancer comparing with laparoscopic right hemicolectomy with transabdominal specimen extraction. Methods Clinical data of the patients with complete laparoscopic right hemicolectomy including 29 cases in transvaginal group and 29 cases in transabdominal group were collected. Comparision between two groups was done for preoperative clinical features, intraoperative indexes, post-operative complications, female sexual function score to charify the impact of the two methods of specimen removal on patients. Results There were no significant differences in intraoperative blood loss, fever and bleeding after operation, intestinal obstruction, anastomotic leakage and other postoperative complications between two groups. Compared with transabdominal group, operative time prolonged [(151.52±33.73) min vs. (179.59±47.02) min, P=0.012 0] and postoperative hospital stay decreased (7.14 d vs. 6.07 d, P=0.013 0) in transvaginal group. The female sexual activity recovered more quickly with less discomfort caused by the scar in transvaginal group and there was no statistical difference in postoperative female sexual function score between two groups. Conclusions CRC-NOSES Ⅷ A could be safe and feasible when compared with conventional laparoscopic hemicolectomy with transabdominal specimen extraction for radical resection of colon cancer. The patients in transvaginal group had less sensation of scars and faster recovery of sexual activity.
