[Surgical treatment of complicated extra-sphincter and trans-sphincter fistulas of the rectum].

172 patients were operated for complicated extrasphincter high fistulas and some transsphincter fistulas of the rectum. All the patients were treated by the proposed method--resection of the fistula in intestinal lumen, splitting of the sphincter, repair of anal canal with pullthrough of the distal rectal segment. Spinal anesthesia leading to good relaxation of the anal canal was used. There were no recurrences in patients folloved up during 2 years. Postoperative bed-day reduces to 12-15. There were no disorders of rectal sphincter apparatus.
