[Surgical treatment for cicatrix strictures of anal canal]

Classification of anal canal strictures with gradation of intensity, extent and localization is proposed. In 12 patients with compensated strictures combination of stenosis and anal fissure served as an indication for operation. These patients underwent fissure excision with dosed sphincterotomy. Anoplasty with displacement of island skin flaps to anal canal defects was carried out to 29 patients with sub-or decompensated strictures after dissection of scarry stricture. Good direct results were achieved in 38 patients. Compensated re-stenosis treated conservatively was observed in 3 patients after anoplasty. It is drawn a conclusion about necessity of differential approach to choice of treatment mode for anal scarry strictures. Anoplasty according to proposed method is considered to be optimal for marked strictures.
