[Causes and prevention of rectal fistula recurrences].

The study of 412 patients with recidivations of rectal fistulas has shown that most frequent recidivations of extrasphincter fistulas are observed in the presence of ramified suppurative cavities in the pararectal fat. The recidivation may be caused by errors in the preoperative diagnosis and inadequate choice of the operation method, by non-radical operations and insufficient control of the postoperative wound healing.
