Anal stenosis, which develops as a result of aggressive excisional hemorrhoidectomy, especially with the stoutly use of advanced technologies (LigaSure, ultrasonic dissector, laser, etc.), has become common, causing significant deterioration in the patient's quality of life. Although non-surgical treatment is effective for mild anal stenosis, surgical reconstruction is unavoidable for moderate to severe anal stenosis that causes distressing, severe anal pain, and inability to defecate. The problem in anal stenosis, unlike anal fissure, is that the skin does not stretch as a result of chronic fibrosis due to surgery. Therefore, the application of lateral internal sphincterotomy does not provide satisfactory results in the treatment of anal stenosis. Surgical treatment methods are based on the use of flaps of different shapes and sizes to reconstruct the anal caliber and flexibility. This article aims to summarize most-used surgical techniques for anal stenosis regarding functional and surgical outcomes.
肛门狭窄是由于激进的切除性痔切除术引起的，尤其是在大量使用先进技术（LigaSure、超声刀、激光等）的情况下，变得很常见，导致患者的生活质量显著恶化。虽然非手术治疗对轻度肛门狭窄有效，但对于引起痛苦、严重肛门疼痛和无法排便的中重度肛门狭窄，手术重建是不可避免的。与肛裂不同，肛门狭窄的问题在于皮肤不会因慢性纤维化而伸展，因为手术。因此，外侧内括约肌切开术在治疗肛门狭窄方面的效果并不理想。手术治疗方法基于使用不同形状和大小的皮瓣来重建肛门口径和灵活性。本文旨在总结肛门狭窄最常用的手术技术，以获得良好的功能和手术效果。
