[Anoplasty with House advancement flap for anal stenosis after hemorrhoidectomy. Report of a clinical case].

Anorectal strictures may occur after anorectal surgery and in particular after surgical haemorrhoidectomy. Anal examination under general anaesthesia was recommended to evaluate the stricture and to choose the appropriate technique. The house advancement flap has been recently proposed for postsurgical anal stenosis repair. The house flap receives its blood supply through unnamed vessels extending through a fatty pedicle from the underlying external sphincter muscle and not from a skin or mucosal bridge like the other common flaps (Y-V and mucosal advancement flap). The aims of this study were firstly to report a case of post-haemorrhoidectomy anal stenosis in a 68-year-old man treated in our institution by house advancement anoplasty and secondly to evaluate the efficacy and safety of this new technique. The technique was totally successful in alleviating anal stenosis and maintaining faecal continence. House advancement anoplasty should be part of the armamentarium of colon and rectal surgeons for treating severe anal stenosis.
