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.

Conclusion: 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.
