目的：通过对比经腹部切口取标本的右半结肠癌手术,探究腹部无辅助切口经阴道拖出标本的完全腹腔镜右半结肠癌根治术（CRC-NOSES Ⅷ式 A法）的近期疗效。方法：分析29例经腹部切口取标本（经腹部组）与29例经阴道拖出标本（经阴道组）的完全腹腔镜右半结肠癌根治术的临床资料。对比两组病人的术前临床特征、术中情况和术后并发症、女性性功能评分,以此来对比两种取标本方式对病人的影响。结果：两组病人术中出血量、术后发热、术后出血、肠梗阻、吻合口漏等并发症发生差异无统计学意义。相对经腹部组,经阴道组病人手术时间较长 [（151.52±33.73） min比（179.59±47.02） min, P=0.012 0],但术后住院时间缩短（7.14 d比6.07 d, P=0.013 0）,术后女性性生活恢复较快,腹部瘢痕影响小,术后女性性功能评分差异无统计学意义。结论：与常规经腹部切口取标本的腹腔镜右半结肠癌根治术相比,规范的CRC-NOSES Ⅷ式 A法安全、可行。经阴道组病人对瘢痕感知较弱、性生活恢复较快。

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.
