    Parks operation for faecal incontinence was performed on 97 patients with total loss of anorectal control due to injury. All had sustained complete division of the anal sphincters as a result of trauma, anal surgery, or obstetric tears and either were incontinent or had been given a colostomy. In all patients the divided sphincters were repaired using an overlapping technique; in 93 the repair was protected by a temporary defunctioning stoma. There was no operative mortality. Continence was completely restored in 65 (78%) and improved in a further 11 (13%) of the 83 patients assessed from four to 116 months postoperatively. Minor complications which did not affect the eventual clinical outcome occurred in 23 patients. Factors associated with failure of the operation included breakdown of the repair in the early postoperative period, fistula, and pelvic floor neuropathy. The results show that even after severe injury to the sphincters surgical reconstruction can restore continence in most patients.
