A comparison of the outcome of the treatment of fissure in ano by a lateral subcutaneous sphincterotomy (LSS) and by an anal dilatation (AD) has been made retrospectively through a questionnaire sent to patients who were operated upon between three months and five years beforehand. The questionnaire was completed by 86 patients who underwent the LSS, and 74 patients who underwent the AD. The two groups were comparable in age, but there were slightly more males in the LSS group. The results appear to favour the LSS, the patients in this group recording a recurrence of pain and problems of incontinence significantly less often than those in the AD group.
通过向3个月至5年前接受手术的患者发送问卷，对侧方皮下括约肌切开术（LSS）和扩肛术（AD）治疗肛裂的结果进行了回顾性比较。86例接受LSS的患者和74例接受AD的患者完成了问卷。两组年龄相当，但LSS组男性略多。结果似乎支持LSS，该组患者疼痛复发和失禁问题的发生率明显低于AD组。
