Anal stenosis is a rare but functionally debilitating complication following excisional hemorrhoidectomy, most often resulting from excessive anodermal resection and circumferential scarring [1]. While mild stenosis may respond to conservative measures, moderate to severe cases frequently require reconstructive surgery [2]. Several anoplasty techniques have been described, including diamond-shaped, rhomboid, Y–V and house advancement flaps, each aiming to provide tension-free enlargement of the anal canal with satisfactory functional outcomes [3, 4]. House flap anoplasty reduces stress at the suture line and improves blood flow to the flap, especially in cases of severe anal stenosis, and compared to rhomboid/diamond and Y–V flap, its complications and recurrence are much lower [2, 4]. We present a surgical video demonstrating a house advancement flap anoplasty performed for symptomatic post-hemorrhoidectomy anal stenosis (Video 1). A 42-year-old male presented with obstructed defecation, painful evacuation and reliance on digital assistance 2 years after Milligan-Morgan hemorrhoidectomy. Despite repeated anal dilatations, moderate stenosis persisted. Based on the degree of fibrosis, circumferential involvement and the need for a well-vascularized, tension-free reconstruction, a house advancement flap was selected. The postoperative course was uneventful. The patient was discharged on the first postoperative day, and follow-up at 1 week confirmed intact wound healing without dehiscence or infection. At 2 months, the patient reported resolution of obstructed defecation symptoms and improved continence. This video vignette highlights the technical principles, indications and outcomes of house advancement flap anoplasty and serves as an educational resource for colorectal surgeons managing moderate post-hemorrhoidectomy anal stenosis.
