[目的]观察经肛双管负压引流+间断冲洗方法预防直肠Ⅰ期手术缝(吻)合口瘘的效果。[方法]2004年1月至2009年10月112例患者随机分为试验组和对照组,试验组(57例)术后经肛门置双管负压引流+间断冲洗,对照组(55例)常规手术后仅作扩肛不置肛管。术后第2、5d两组分别作吻合口旁肠腔内测压,并观察两组吻合口瘘发生率。[结果]试验组术后第2、5d吻合口旁肠管测压值显著低于对照组(P<0.05),试验组吻合口瘘发生率显著低于对照组(P<0.05)。[结论]经肛门置双管负压引流+间断冲洗方法可降低直肠Ⅰ期手术缝(吻)合口瘘的发生率。
[Objective] To observe the effect of transanal double negative pressure drainage and intermittent irrigation to prevent fistula in stage Ⅰ rectal surgery. [Methods] From January 2004 to October 2009, 112 patients were randomly divided into experimental group and control group. In the experimental group (57 cases), double negative pressure drainage and intermittent irrigation were performed in the experimental group, while in the control group (55 cases) Routine surgery for anal anal canal only. At the 2nd and 5th postoperatively, the anastomotic intestinal pressure was measured in each group, and the incidence of anastomotic fistula was observed. [Results] The anastomotic intestinal pressure values in the experimental group at 2 and 5 days after operation were significantly lower than those in the control group (P <0.05). The incidence of anastomotic fistula in the experimental group was significantly lower than that of the control group (P <0.05). [Conclusion] The double-tube negative pressure drainage and intermittent irrigation through the anus can reduce the incidence of stage Ⅰ (suture) fistula.
