Introduction: Benign anal stenosis is not uncommon, often disabling and incapacitating condition, occurring mainly after anorectal surgery/procedures. Both non‐surgical and surgical treatments have been advocated in the treatment of anal stenosis with mixed results. The aim of anoplasty is to restore normal function to the anus by excising/ dividing the stricture and widening the anal canal by various plastic surgery techniques. Many methods have been used for the treatment of anal stenosis with variable results. It is extremely difficult to reproduce the results of the anoplasty procedures described in the literature as prospective trials are very few in number and anal manometry is not widely available/affordable. This review examines the outcome of surgical treatment of benign anal stenosis in the form of VY anoplasty with lateral sphincterotomy. This study attempts to evaluate the efficacy of this procedure in the management of anal stenosis. Methods: A prospective clinical study was undertaken over a 1 year period on ten patients operated for anal stenosis with v-y anoplasty+lateral sphincterotomy. Result: Ten (10) patients with benign anal stenosis were treated in our surgery department. Local administration of chemical injections by RMPs (6cases), overzealous haemorrhoidectomy (2 cases), chemical burns (2 cases) were the etiology of anal stenosis in the present study. All the patients underwent surgical treatment after poor response to non-operative management which included bowel softeners, sitz baths, graded metallic anal dialators. The patients underwent V-Y anoplasty with unilateral lateral internal sphincterotomy. Prior to this procedure the patients underwent diversion loop sigmoid colostomy four weeks before the V-Y anoplasty. The post-operative period of these patients were uneventful.There was no re‐operation and only minor complications were present in two patients: anal pruritus and one with temporary incontinence for flatus.
