腹腔镜下全直肠系膜切除术后肛门功能研究

Research of anal function after total mesorectal excision

目的研究腹腔镜下全直肠系膜切除术对肛门功能的影响。方法 80例直肠癌患者随机分为开腹手术组及腔镜组,每组40例,分别行传统开腹手术及腹腔镜手术。通过Wexner评分系统对比两组患者术后肛门功能情况。结果术后3、6个月,腔镜组患者肛门功能良好率82.5%、87.5%分别高于开腹手术组患者的60.0%、67.5%,差异具有统计学意义(P<0.05)。结论腹腔镜下全直肠系膜切除术相比传统开腹手术在保留肛门功能方面有一定优势。

Objective To study influence of laparoscopic total mesorectal excision on anal function. Methods A total of 80 patients with rectal carcinoma were randomly divided into laparotomy group and laparoscope group, with 40 cases in each group. Traditional laparotomy and laparoscopic surgery were performed in each group. Postoperative anal function was compared by Wexner scoring system between the two groups. Results In the postoperative 3, 6 months, the good rates of anal funcation in laparoscope group were 82.5% and 87.5%, which were all higher than 60.0% and 67.5% of the laparotomy group. The difference had statistical significance（P〈0.05）. Conclusion Laparoscopic total mesorectal excision has a certain advantage in retaining anal function than traditional laparotomy.
