FIELD: medicine.
SUBSTANCE: invention relates to medicine, namely to proctology. A method for surgical treatment of extrasphincteric fistulas of the rectum is proposed. An external fistulous opening with a fistula is excised to the muscular layer of the rectal wall. Stepping back 2-5 mm from the dentate line, a channel is formed in the intersphincter space parallel to the wall of the rectum to the internal fistulous opening without damaging the fibers of the internal sphincter. A ligature is passed through the formed channel. 40-50 days after the perineal wound has healed by secondary intention, the ligature is excised as a single block with the muco-submucosal layer of the rectum.
EFFECT: method allows to reduce the risk of anal incontinence, reduce the risks of purulent-septic complications, and prevent the recurrence of this disease in the future.
