闭式切断术治疗肛裂30例疗效观察

Closed Excision in the Treatment of Anal Fissare Olinica Effect Observation of 30 Cases

为观察闭式切断术治疗肛裂的疗效，将60例Ⅲ期肛裂患者随机分为治疗组和对照组，每组30例。治疗组采用闭式切断部分内括约肌治疗，对照组采用单纯肛裂切除敞开疗法，术前术后处理相同。结果显示，两组患者均治愈，无并发症发生。治疗组平均愈合时间为（13．3±3）d，对照组为（16．4士4）d，两组比较差异有统计学意义（P〈O．05）。术后6个月复发率治疗组低于对照组（P〈O．01）。结果表明，闭式切断术治疗肛裂具有创面愈合时间短，复发率低等优点。

In order to observe the clinical efficacy of closed excision in the treatment of anal fissure, 60 pa- tients with anal fissure of stage Ⅲ were randomly divided into treatment group and control group,30 pa- tients for each. Closed incision of part of the internal sphincter was performed on treatment group, while simple resection of anal fissure and open wound on control group. Both groups were managed in the same way preoperatively and postoperatively. The results showed that both groups were cured, with no incidence of complications. The average healing time.was （13.3±3）in treatment group and （16.4＋4）d in control group, and statistically difference was found between them（ P 〈0.05）. Compared with control group, the recurrence rate 6 months after surgery was significantly lower in treatment group （ P 〈0.01）. It is conclu- ded that closed excision is of shorter wound healing time,low recurrence rate in treating anal fissure.
