Purpose:
We report our clinical experience with the perineal canal and suggest the management.
Materials And Methods:
Retrospective chart review of patients with perineal canal were classified by lesion characteristics into Group I: active perineal inflammation, Group II: vulvar excoriation and Group III: no active inflammation. Group III patients underwent primary surgical repair. Group I and II patients underwent repair after medical management. The fistula was repaired by the modified Tsuchida's technique consisting of an anterior anopullthrough and excision of the fistula tract (reverse order).
Results:
Between September 1999 and August 2003, we treated 120 cases of perineal canal. Group I, II and III consisted of 74, 12 and 34 patients, respectively. In two patients of Group I (2.7%), the fistula tract spontaneously closed. The remaining 118 patients were surgically treated with the modified Tsuchida's technique. Recurrences were similar between patients treated with colostomy (1/28 or 3.6%) versus without colostomy (3/90 or 3.0%), as well as between patients initially treated with primary repair (3/102 or 2.9%) versus patients undergoing reoperation with redo repair (1/16 or 6.25%).
Conclusions:
With proper initial medical treatment, the perineal canal could be repaired successfully in one stage with the modified Tsuchida's technique.

Muscles of the Pelvic Floor and Perineum
Perineal Layer
The perineum is a diamond-shaped area below the pelvic diaphragm, divided into an anterior urogenital triangle that contains the external genitals and a posterior anal triangle housing the anus. The urogenital...
Large Intestine
The ileocecal sphincter, a mucous membrane fold, guards the opening from the ileum to the large intestine. This valve permits material from the small intestine to pass into the large intestine. Attached to the ileocecal valve is the cecum. This small pouch, approximately 6 cm long, has a twisted, coiled tube known as...
