[Surgical treatment of combined trans-sphincter and extra-sphincter rectal fistula].

The results of surgical treatment of 600 patients with rectal fistula were analyzed. Intrasphincter fistula was observed in 204 patients (34%), transsphinctered fistula--in 72 patients (12%), extrasphincter fistula--in 324 patients (54%). In order to decrease the rate of recurrence of fistula, during performance of plastics of internal hole of the fistula the graft of all the wall of rectum (not only its mucosa) was mobilized up to the level of anal sphincter. Post-operative complications and recurrence of fistula occurred in 4% of patients.
