目的 研究低位三管引流预防直肠癌保肛术后吻合口漏的效果.方法 2006年1月至2010年12月共220例直肠癌患者进行保肛术(治疗组),术中经肛门放置双管引流,经肛旁于骶前腔内放置双套引流管.选取2001年1月至2005年12月间205例经左下腹壁于盆腔放置引流管的患者作对照组.对照两组患者术后切口感染率及吻合口漏率进行对比分析.结果 切口感染、吻合口漏发生率:治疗组分别为8.18% (18/220),2.27 % (5/220);对照组分别为7.80%(16/205),8.78%(18/205).两组切口感染发生率差异无统计学意义(P>0.05),吻合口漏发生率治疗组显著低于对照组(P <0.05).结论 低位三管引流可显著降低低位直肠癌保肛术后吻合口漏的发生.%To investigate effect of low three tube drainage in preventing anastomotic leakage after anus-preserving operation in rectal cancer. Methods From January 2006 to December 2010, two hundred and twenty patients with rectal cancer underwent anus-preserving operation (treatment group). In treatment group, two tubes were placed in the colonic cavity and one tube was placed in the presacral cavity. From January 1999 to December 2005, two hundred and five patients with rectal cancer underwent anus-preserving operation (control group). In control group, only one tube was placed in the pelvic cavity through left lower abdominal wall. The postoperative complications were compared in two groups. Results Occurrence of wound infection and anastomotic leakage were 8. 18% (18/220) in treatment group and 2.27% (5/220) in control group. In the control group, 7.80% (16/205) wound infection and 8. 78% (18/ 205) anastomotic leakage occurred. The incidence of anastomotic leakage in the control group were statistically higher than that in the treatment group ( P <0. 05). Conclusion Low three tube drainage can effectively prevent anastomotic leakage after anus-preserving operation in rectal cancer.
