A VVF that is larger may require the use of additional sources of tissue. A graft called the Martius graft, or labial fibrofatty tissue graft, is sometimes used to reinforce repairs of larger fistulas, even those that are high in the vaginal vault. The procedure involves a vertical incision on the inner side of the labium majus and detachment of fibroadipose tissue from its underlying bulbocavernosus muscle. This fat-pad flap is vascularized and thus serves as a pedicled graft. It can be tunneled under the vaginal epithelium to reach the site of closure. The procedure has limited use with the vaginal approach to VVF, but is important to be aware of.
Other sources of grafts or flaps that can sometimes be used with the vaginal approach include the gracilis muscle, the gluteal muscle and peritoneum, and fasciocutaneous tissue from the inner thigh.
The avoidance of overlapping suture lines and multiple layers of closure will help ensure a water-tight closure. If there is any leakage upon testing the integrity of the repair, particularly one that is vaginally approached, such leakage will continue and the repair will have been unsuccessful. In an abdominal surgery for VVF, a small amount of remaining leakage will probably resolve on its own after 10-14 days of catheter placement.
Placement of a Jackson-Pratt (JP) drain is controversial. It has been suggested that a JP drain placed on continuous suction will pull urine out of the bladder and increase the risk of a fistula. I don’t place a JP drain in my repairs as I find them to not be helpful. A cystogram can be done 1 week after repair to confirm healing, but there is some debate about whether or not the procedure is useful at that point. In my experience, if the patient does not have a cystogram and gets postrepair leakage, I have the same information as I would have obtained through a positive finding on a cystogram.
