低位三管引流预防低位直肠癌保肛术后吻合口瘘的效果

目的观察低位三管引流预防低位直肠癌一期切除吻合术后吻合口瘘的效果。方法将1985年1月至2007年12月1302例低位直肠癌患者按术后引流方式分为两组。低位三管引流组（822例）术中经肛门吻合口上放置肠腔内双管引流，经肛管旁放置一盆腔引流管。对照组（480例）仅经肛管旁放置一骶前腔引流管。对两组患者术后并发症进行分析。结果切口感染、吻合口瘘发生率：引流组分别为8．9％、2．2％；对照组分别为9．4％、8．1％。两组切口感染发生率相比差异无统计学意义（P〉0．05），引流组吻合口瘘发生率显著低于对照组（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瘘的发生率。

Effects of drainage by three lower tubes on preserving operation for lower rectal cancer

Objective To investigate the effects of drainage by three lower tubes in preventing anastomotic leakage after preserving operation for lower rectal cancer. Methods From January 1985 to December 2007, 1302 patients with lower rectal cancer were allocated to two groups in order of admission. In the drain group, two tubes were placed in the colonic cavity and one tube was placed in the presacral cavity. In the control group, only one tube was placed in the presacral cavity .The postoperative complications of the two groups were compared. Results The occurrence rates of wound infection and anastomosis leakage were 8.9% and 2.2% respectively. In the control group, there were 9.4% for wound infection and 8.1% for anastomosis leakage. The incidence of anastomosis leakage in the control group was statistically higher than that in the drainage group (P<0.05). Conclusions Drainage by three lower tubes can effectively prevent anastomosis leakage after annus-preserving operation for lower rectal cancer.
