Martius labial fat pad graft (use in rectovaginal fistula repair).

INTRODUCTION AND HYPOTHESIS: The objective is to demonstrate the utility of the Martius labial fat pad graft in pelvic fistula repair.

METHODS

An incision is made over the labium majus from the level of the clitoral hood superiorly and extending inferiorly to the level of the labiocrural fold. The fibrofatty graft is then mobilized from the adjacent labium majus. The flap can be divided either at its anterior or at its posterior pedicle. A subepithelial defect is created through which the flap will be passed. The flap is sewn into place by attaching it to the underlying rectovaginal fascia without associated tensioning. Next, the posterior vaginal wall is closed over the graft with a series of everting subepithelial mattress sutures followed by a reinforcing layer of interrupted #1 Vicryl through the vaginal epithelium.

CONCLUSIONS

The advantages of the Martius flap in fistula repair include low morbidity, lack of a cosmetic defect, and the need for only a single surgical field. Its prominent fibrous component makes it a stronger graft than adipose tissue from other areas and its abundant blood supply promotes rapid neovascularization and lends itself well to many surgical modifications that can be utilized in even the most difficult of fistula repairs.
