内括约肌侧方切开术治疗肛裂30例疗效观察

Lateral Internal Sphincterotomy for Anal Fissure：Clinical Effect Observation of 30 Cases

为探讨白内向外内括约肌侧方切开术治疗肛裂的疗效，将60例肛裂患者随机分为两组即观察组和对照组，每组各30例。观察组采用自内向外内括约肌侧方切开术治疗，对照组采用开放式内括约肌后方切开术治疗，比较两组患者手术时间、创口愈合时间、住院时间及术后疼痛评分情况，并进行统计分析。结果显示，观察组在手术时间、创口愈合时间、住院时间及术后疼痛评分方面均优于对照组（P〈0．05或P〈0．01）。结果表明，自内向外内括约肌侧方切开术治疗肛裂安全有效，术后疼痛轻，并发症少，恢复快。

In order to observe the clinical efficacy of anal fissure treated by lateral internal sphincterotomy from inside to outside,60 cases were randomly divided into observation group and control group,30 cases for each group. Observation group underwent lateral internal sphincterotomy （from inside to outside）, con- trol group received open posterior internal sphincterotomy. Both groups were compared for operation dura- tion, wound healing time, hospital stay and scores of postoperative pain, and taken for statistical analysis. The results showed that observation groups was superior to control group in operation duration, wound healing time,hospital stay and scores of postoperative pain （ P 〈0.05 or P〈0.01）. It is concluded that lateral internal sphincterotomy from inside to outside is effective, safe with less postoperative pain, fewer complications and rapid recovery.
