Anoplasty for Post-hemorrhoidectomy Low Anal Stenosis: A New Technique

World J Surg. 2018 Sep;42(9):3015-3020. doi: 10.1007/s00268-018-4561-6.


Background: Post-hemorrhoidectomy anal stenosis though rare is very disturbing and devastating complication. Many surgical procedures have been described, but despite good results, many complications can ensue like flap necrosis, mucosal ectropion, and restenosis.

Objective: We report a new simple technique for repair of severe/moderate anal stenosis which requires no extensive flap mobilization or many sutures.

Patients and interventions: This is a personal series of 65 patients treated over a period of 20 years. The data were prospectively recorded by the author. The essence of this simple procedure is mobilizing the anal mucosa to the dentate line via a vertical incision and mobilizing the adjacent perianal skin and subcutaneous fat to allow a completely tension-free approximation of the perianal skin and the anal mucosa which are sutured together transversely. A tension-releasing incision is made in the perianal region which is left to heal by secondary intention.

Results: Fifty-nine patients (90.8%) continued the 5-year follow-up, and 6 patients left the country after 2 years of follow-up. There was only one case of recurrence after 2 years, which was treated by a second anoplasty. Four patients (59-66 years old) developed transient urine retention after surgery. One patient developed partial dehiscence of the suture line which was treated conservatively. No mucosal ectropion or perianal skin necrosis was observed. Complete healing of the perianal tension-releasing wound was within 2-3 months. By the third week after surgery, all the patients discontinued use of stool softeners or laxatives and were able to defecate comfortably.

Conclusions: This procedure is simple and requires little dissection and only a few sutures with minimal complications. It is suitable for low severe and moderate anal stenosis.
