The results of subcutaneous lateral internal sphincterotomy for chronic fissure-in-ano were analyzed in a series of 60 patients operated upon over a period of two years. Immediate relief from pain with painless first bowel movement was accomplished in 97 per cent of the patients with very low morbidity rates. All patients were treated on an outpatient basis and had a minimum follow-up of two years without any recurrences. The incidence of sphincter dysfunction is very low and is usually only temporary.
对60例慢性肛裂患者进行了皮下外侧内括约肌切开术的结果分析，这些患者是在两年时间内接受手术的。97%的患者术后立即缓解疼痛，首次排便时无痛，发病率极低。所有患者均在门诊接受治疗，最少随访两年，无任何复发情况。括约肌功能障碍的发生率非常低，通常只是暂时的。
