FIELD: medicine; coloproctology.
SUBSTANCE: pelvic topography type is determined. Rectum wall is repaired in area of inner sinus tract following surgical d-bridement of scar tissues within sinus tract. Within external edge of perineum operative wound inner portion of gluteus maximus muscle is free from cellular tissue and cut out for complicated U-shaped fasciomuscle graft based on primary branches of lower gluteal neurovascular beam. Muscular part of graft is penetrated into residual cavity, and fascial part of complicated graft is fixed to rectum wall through separate interrupted catgut suture at symphysis-petal pelvic topography angled 90° to pelvic horizontal axis. At sacropetal pelvic topography it is fixed angled 120° to pelvic horizontal axis.
EFFECT: enables to provide plastic area revasculization; prevents infiltrative inflammatory and suppurative complications; fixes internal opening; reduces possibility of fistula relapse.
