Abstract

Purpose

The aim of this study was to investigate risk factors for recurrence in the perineal canal (PC).

Methods

Patients with PC who underwent operations were enrolled in this study and were divided into recurrence and non-recurrence groups. Preoperative infection, the age at the operation, the presence of colostomy and the treatment procedure for fistula were retrospectively investigated. Regarding the treatment procedure for fistula, either closure of the rectal wall with stitches or ligation of fistula in the rectum was performed. These factors were compared between the two groups.

Results

Six of 17 patients with PC who underwent surgical treatment had recurrence. There were no significant differences in the incidence of preoperative infection, age at operation or presence of colostomy (p = 0.60, 0.38, 1.00, respectively). In the recurrence group, all patients were treated by closure of the rectal wall. In the non-recurrence group, five were treated by the closure of the rectal wall with stitches and six by ligation of the fistula. There was a significant association between recurrence and the treatment procedure for fistula (p = 0.04).

Conclusion

Closure of the rectal wall with stitches is a risk factor for the recurrence of PC.
