Anoplasty for Anal Stenosis

Anal Stenosis is a rare and serious complication of anorectal surgery most often seen after having a hemorrhoidectomy. Anal stenosis is a narrowing of the anal canal, which reduces the area’s ability to function leading to painful or difficult bowel movements. The causes of anal stenosis include trauma, inflammatory bowel disease, venereal disease, radiation therapy, tuberculosis, chronic laxative abuse, and 90% of anal stenosis cases are caused by hemorrhoidectomy. The definition of anoplasty is the reconstructive surgery of the anus.


There are many different types of Anoplasty including the Y-V Advancement Flap, V-Y Advancement, Diamond-Shaped Flaps, U Flap, C Flap, House Flap, Rotational S-Flap, Internal Pudendal Flap Anoplasty, and the Foreskin Anoplasty. The doctor will discuss with you which surgery best suits your situation.


Possible complications include loss of vascular supply creating flap necrosis, suture dehiscence, failure to correct the stenosis, sloughing of the flap, donor site problems, contracture of the edge of the flap, pruritus, UTI, and infection or sepsis.
