We studied 65 consecutive ambulatory patients with chronic anal fissure that were treated by sphincterotomy under local anaesthesia. The patients were allowed to leave the clinic immediately after the operation. Healing rate was determined three to four months postoperatively by clinical examination and proctoscopy. Fifty-seven patients (88%) were free of symptoms and the fissure was healed. Eight unhealed patients were subjected to a repeated procedure under local anaesthesia, leaving two unhealed patients, that were operated with open sphincterotomy under general anaesthesia. We conclude that local anaesthesia can be recommended for the closed lateral subcutaneous sphincterotomy in ambulatory treatment of chronic anal fissure.
我们研究了65例连续性慢性肛裂门诊患者，这些患者均接受了局部麻醉下的括约肌切开术治疗。术后患者可立即离开诊所。术后三到四个月通过临床检查和直肠镜检查确定愈合率。57例患者（88%）无症状且肛裂已愈合。8例未愈合患者在局部麻醉下接受了重复手术，仍有2例未愈合患者，这2例患者接受了全身麻醉下的开放性括约肌切开术。我们得出结论，在慢性肛裂的门诊治疗中，局部麻醉下的闭合性外侧皮下括约肌切开术是可以推荐的。
