Brief Summary:
This prospective randomized study included 60 consecutive patients suffering from anal stenosis in the period from April 2002 to December 2008. They admitted to colorectal surgery unit, Mansoura university hospital, Egypt. According to the classification proposed by Milson and Mazier(5), all patients had moderate to severe anal stenosis. There were 43 males and 17 female with a mean age 34 + 5.2 years ranging from 18 up to 63 years.

Arm Intervention/treatment
Active Comparator: house advancement flap
house advancement flap
Procedure: house advancement flap group
A house flap of healthy tissue was incised to the depth of ischiorectal fat. The flap consisted of skin and subcutaneous tissue. The flap was sufficiently mobilized without undermining its fatty base containing perforating blood vessels. The flap should be loose and easily advanced into the anal canal. When the ''base'' of this house-shaped flap was advanced into the anal canal defect, it was fixed to the top of the excised area with 3/0 Vicryl sutures.
Other Name: group 1

Active Comparator: Rhomboid flap
rhomboid flapa was incised in the ischiorectal fossa. Without undermining of its fatty base, the flap was then mobilized into the anal canal so that the tip could be sutured to the top of the strictured area using Vicryl 3/0 sutures
Procedure: Rhomboid flap GROUP
A rhomboid flap was incised in ischeorectal fossa and was mobilized without undermining of its fatty base into the anal canal so that the tip of rhomboid flap is sutured to the top of stricured area using vicryl 3/0.
Other Name: Group 11

Active Comparator: Y-V anoplasty
Y-V anoplasty
Procedure: Y-V anoplasty GROUP
Y-V anoplastyis performed by making a v shaped incision in the perianal skin posteriorly starting from the lower end of the wound resultant from excision of scared area. A V-shaped flap is then dissected with preservation fatty base .The V flap is then advanced into the anal canal so that its tip is sutured to the top of structured area using vicryel 3/0.
Other Name: group 111
