FIELD: medicine.
SUBSTANCE: invention relates to medicine, namely to surgery, and may be used to eliminate high level rectovaginal fistulas. Transvaginal approach is used to mobilize an anterior rectal wall, an upper edge of the external and internal anal sphincters along the anterior semicircle, a proximal third of the anal canal wall. Fistulous passage is separated to the intestinal wall without disturbing the integrity of its lumen. Directly adjacent to the intestinal stack, the fistulous passage is ligatured. Fistulous duct is cut above ligation zone. Duplication of the intestinal wall is created, where the ligature fistulous passage is immersed. Duplicated duplicated region is transposed in the distal direction under the internal sphincter in the proximal third of the anal canal.
EFFECT: method enables to reduce a risk of recurrence.
