小针刀法治疗肛门狭窄的临床研究

Clinical study of anal stenosis treated by scalpel therapy

目的观察小针刀治疗肛门狭窄的疗效，并与止血钳法对比。方法治疗组小针刀侧方潜行切断内括约肌134例，对照组止血钳挑出切断内括约肌，并作切口缝合134例。结果对Ⅰ°～Ⅱ°肛门狭窄，治愈率无显著性差异（P〉0．05），而术后疼痛、并发症发生率方面，两组有显著性差异（P〈0．05）。结论小针刀法和止血钳法均适用于Ⅰ°和部份Ⅱ°肛门狭窄，且小针刀优于止血钳，但不适用于Ⅲ°肛门狭窄。

Objective To observe the efficacy of scalpel therapy in treatment of anal stenosis and compared with haemostat method. Methods Small needle knife sneaked and cut down internal sphincter in 134 cases in side direction （treatment group）. The haemoatat picked out and cut down internal sphincter and suture cut in 134 cases （control group）. Results For Ⅰ°～Ⅱ°anal stenosis, there was no significant difference in healing rate （P〉0.05） of the two groups. There were significant difference in postoperation pain and complication incidence rate（P〈0. 05） of the two groups. Conclusion For Ⅰ° and partly Ⅱ° anal stenosis, scalpel therapy is better than aemostat method.
