Controlled Lateral Sphincterotomy in the Treatment of Chronic Anal Fissure：Clinical Therapeutic Effect

为探讨控制性括约肌侧切术治疗陈旧性肛裂的疗效，将118例陈旧性肛裂患者随机分为两组，分别采用控制性内括约肌侧切术（治疗组）和传统的内括约肌侧切扩肛术（对照组）治疗，并对比分析两组治疗结果。结果显示，两组患者均一次性治愈，均无大便失禁发生。但治疗组和对照组分别有1例和6例肛门气体失禁。随访至今，治疗组无复发，对照组复发1例。结果表明，控制性括约肌侧切术减少了不必要的组织损伤，更好地保护了肛门功能，可～次性治愈陈旧性肛裂，且操作简单，适合基层医疗单位推广应用。

The objective of this study was to investigate the therapeutic effect of controlled lateral sphincterotomy for chronic anal fissure. The 118 patients with chronic anal fissure were random divided into treatment and control group;treatment group was subjected to controlled lateral sphincterotomy,control group to routine internal sphincterotomy laterally with dilating anus;the treatment outcomes of both groups were compared each other and analysed. As results, all of the patients of both groups were all cured primarily, and no incontinence of feces was found,but gas incontinence happened in one case of treatment group and 6 cases of control group follow-up（from 2006 yr. , to now） showed no recurrence in treatment group and 1 case in control group suffer from recurrence.
