[The functional and morphological changes in the intestinal sphincter apparatus created by muscle flaps on a fixed vascular-neural pedicle].
Adaptive reaction to new conditions of functioning were studied morphofunctionally in an intestinal sphincteric apparatus formed by mm. gracilis, adductor longus, rectus femoris and semitendinosus in 100 experimental animals. It is established that reorganisation of vascular bed and muscular grafts mobilitive activity finishes up by 30th postoperative day and it is day 90 for morphological structures. Even at distant terms of the observation transplants preserve the structure of muscular tissue. Mm. gracilis and rectus femoris were established to be the preferable material in sphincteroplasties.
