Intravesical mini-laparoscopic repair of vesicovaginal fistulas
Abstract Vesicovaginal fistulas (VVF) constitute the most common type of genitourinary fistulas. In developed coun-tries, VVF are almost always iatrogenic and frequently a sec-ondary result of gynecological surgery. Some minimally inva-sive techniques have been introduced to decrease the morbid-ity related to standard open procedures for the treatment of VVF. One such procedure is the intravesical mini-laparoscopic approach. The aim of this study was to present our initial clinical experience using this technique for transvesical VVF repair. In 2013 and 2014, we carried out mini-laparoscopic repair of VVF in two women who did not respond to conservative treatment with a Foley catheter. The procedure was performed transvesically with a 3-mm instru-ment and a 5-mm, 30° scope. The fistulous tract was dissected and partially excised. The bladder and vaginal wall defects were closed in two layers with two separated continuous barbed, resorbable 3-0 sutures (V-Loc 90 Absorbable Wound Closure Device; Covidien, Norwalk, CT, USA). The median operative time for the two patients was approximately 100 min, and the blood loss was not clinically significant. The patientswere released from the hospital 24 h after surgery. A Foley catheter was left in place for 14 days. Imaging exam-inations performed 6 weeks postoperatively revealed noVVF. In patients with simple fistulas, this technique provides a min-imally invasive, easily reproducible approach with few asso-ciated complications. Nevertheless, further experience and ob-servations are necessary.
