METHOD FOR SURGICAL TREATMENT OF CICATRICIAL STRICTURE OF ANAL CANAL

摘要

FIELD: medicine, surgery, coloproctology.;SUBSTANCE: it is necessary to dissect a stricture in radial direction, partially dissect cicatricial tissues. The quantity and localization of stricturotomic incisions depend upon localization of cicatricial narrowing and its degree. Out of the skin in perianal area starting from distal edge of stricturotomic incision one should cut a skin fragment at complete separation against surrounding skin by keeping a pedicle out of submucous-fatty fiber. Fragment is of oval or rhomboid shape being protruded in radial direction against anal canal. The size of this fragment corresponds to the size of the defect developed after dissecting cicatricial tissues. One should move the fragment into the defect together with a pedicle to fix it along the whole perimeter. The wound of perianal skin developed after replacing the fragment should be sutured in. The innovation enables to decrease traumatism of operation, avoid the development of subfragment space, reduce the size of the cut fragment and keep its valuable blood supply, decrease fragment's stretching and its retraction.;EFFECT: higher efficiency of therapy.;2 dwg, 2 ex
