Abstract
To evaluate the application of Parks' classification in the management of patients with fistula-in-ano, a study was undertaken to assess the outcome of surgery, especially with respect to the recurrence rate and alteration of continence. A retrospective analysis of 160 consecutive patients who were classified at the time of operation was conducted. The distribution of fistulas was as follows: intersphincteric, 41.9 percent, transsphincteric, 52.1 percent, suprasphincteric, 1.3 percent, extrasphincteric, 0. A horseshoe extension occurred in 8.8 percent of the fistulas and 3.8 percent did not exactly conform to the classification as they were either complex or combinations of more than one type of fistula. The sole immediate postoperative complication was bleeding, which occurred one week postoperatively and ceased spontaneously (0.7 percent). Alteration in continence occurred in 6 percent of patients with 2.6 percent experiencing temporary incontinence to flatus, 1.3 percent to liquid stool, and 0.7 percent to solid stool. Permanent loss of control for flatus occurred in one patient (0.7 percent) and for liquid stool in one patient (0.7 percent). No patients suffered loss of control for solid stool. Recurrence developed in 6.3 percent of patients, all between five and 25 months postoperatively. Classifcation was found to be a useful guide in the operative management of patients with fistula-in-ano.
