Anal stenosis is a late hemorrhoidectomy complication. Sphincterotomy and various anoplasty techniques are used for treatment severe anal stenosis, such as the C flap, House flap, U flap, and rotational S flap, but no procedure is ideal for every patient. We review 2 cases of severe circular anal stenosis. Their complaints included narrow caliber of the stool and feeling unsatisfied defecation. Excision of scar tissue using the circular technique was followed by reconstruction using the bilateral rotational S flap procedure. At the 1-year follow-up, the patient had complaints about neither defecation nor pain, and no longer needed laxative agents. In conclusion, the bilateral rotational S flap technique should be considered as a viable treatment because it can also prevent the occurrence of restenosis, especially given the consideration of adequate blood supply.

Abstract PDF: PURPOSE
The surgical treatment of anal stenosis includes internal sphincterotomy, rotaton flap and advancement flap according to the stenosis degree, recently, Christensen performed house shaped advancement flap and reported fair results. We compared and analyzed the surgical methods and results in patients with moderate and severe anal stenosis who underwent house shaped advancement flap and C-anoplasty.
METHODS
We have performed this study with 6 cases using the house shaped advancement flap and 6 cases using the C-anoplasty. The out come was assessed by clinical characteristics, surgical method, operation time, duration of hospitalization, healing time, postoperative complications, results.
RESULTS
The average operation time was 38 min in those house shaped advancement flap cases and 63 min in C-anoplasty cases. The average time of hospitalization was 6 days and 9 days, respectively, and the average time of healing was 28 days and 46 days, respectively. In those house advancement flap cases, surgery could be done in 2 directions at the same time in 4 cases and 3 directions in 2 cases; as for those C-anoplasty cases, surgery could be done in 1 direction in 4 cases and 2 directions in 1 case. Two complications were observed in C-anoplasty, one flap infection and one flap necrosis, and in house shaped advancement flap, no complication was observed.
CONCLUSIONS
House shaped advancement flap have several advantages compared to the C-anoplasty, and since house shaped advancement flap could be performed in 2 to 3 directions or even 4 directions at the same time, the anus could sufficiently expanded in severe anal stenosis patients. The house shaped advancement flap might be one of the good method in treating anal stenosis.
