Benign anal stenosis is an uncommon, disabling and incapacitating disease, occurring mainly after anorectal surgery. Both non-surgical and surgical treatments have been devised in the treatment of anal stenosis with good results. We described the results of the treatment of this disease in the Coloproctology Department of our institution.
A retrospective clinical study was undertaken over a 5-year period for consecutive patients operated on for anal stenosis.
Twenty-three patients with benign anal stenosis were treated in our department. Haemorrhoidectomy was the most common cause of anal stenosis (74%). Nineteen patients with moderate to severe symptoms of anal stenosis underwent surgical treatment. Lateral mucosal advancement flap was the most frequently carried out operation (63.1%). Four patients were treated with anal dilatation (17.3%). All patients had remission of the preoperative symptoms. There was no re-operation and only minor complications were present in four patients: three patients with anal pruritus and one patient with temporary incontinence.
The easy performance, the absence of major complications and the good results obtained confirm that these methods are effective and safe in the treatment of anal stenosis.
良性肛门狭窄是一种罕见的、导致残疾和功能丧失的疾病，主要发生在肛肠手术后。针对肛门狭窄，已经设计出了非手术和手术治疗方法，且效果良好。我们描述了我院结直肠外科对该疾病的治疗结果。
对连续5年接受肛门狭窄手术的患者进行回顾性临床研究。
我院共治疗了23例良性肛门狭窄患者。痔切除术是肛门狭窄最常见的原因（74%）。19例有中度至重度肛门狭窄症状的患者接受了手术治疗。侧方黏膜推进皮瓣术是最常实施的手术（63.1%）。4例患者接受了肛门扩张治疗（17.3%）。所有患者术前症状均缓解。无再次手术情况，仅4例患者出现轻微并发症：3例肛门瘙痒患者和1例暂时性失禁患者。
操作简便、无重大并发症且效果良好，证实了这些方法在治疗肛门狭窄方面有效且安全。
