Laparoscopic repair of vesicovaginal fistula caused by radiation therapy: Use of a perirectal fat interposition graft.

ABSTRACT:

Introduction

We present a case of laparoscopic repair of vesicovaginal fistula caused by radiation therapy using a perirectal fatty tissue interposition graft.

Case presentation

A 72-year-old woman was diagnosed with vesicovaginal fistula induced by radiation therapy. Repair of the vesicovaginal fistula was achieved via laparoscopic approach. The fistula was exposed, followed by excision of fistula tract, fine dissection to achieve a traction-free approximation of bladder mucosa, then water-tight closure. An interposition graft derived from the perirectal fat was inserted to reduce the risk of repair failure. The patient did not have the incontinence problem at 1-year follow-up.

Conclusion

The laparoscopic approach for vesicovaginal fistula repair is minimally invasiveness. Preparation of the interposition graft derived from the perirectal fatty tissue was easy and its mobility to achieve closure of the fistula was acceptable. Thus, this procedure is feasible for the repair of poorly vascularized tissues such as radiation-induced fistulas.

Same problem, different approaches: transvesical and extravesical laparoscopic vesicovaginal fistula repair-case report.

Project description:Vesicovaginal fistulas (VVaFs) are relatively uncommon in developed countries but with devastating consequences for the women suffering them. Conservative management has a low response rate. The surgical repair is a technically demanding procedure. Transvaginal, open transabdominal or laparoscopic (pure or robot-assisted) approaches have been described with similar post-operative results. We report two real-life cases of VVaF after surgery of benign gynaecological conditions, both presenting with continuous urinary incontinence and repaired with laparoscopic surgery. The first case had a simple tract above the trigone and was managed with an extravesical approach. The second is a complex case with multiple fistulous tracts that required a transabdominal-transvesical approach (modified O'Connor technique). Both patients have their fistula closed and are continent after surgery with a mean follow-up of 9 months. Given the lack on evidence for the selection of the best approach, it is important to report the outcomes with the different surgical techniques in both simple and complex fistulae. A pre-operative exhaustive study of the location and number of fistulous tracts is essential, as well as selecting the technique which best allows tissue dissection and tension-free suture to get a successful closure. Therefore, knowledge of several procedures and approaches is mandatory when dealing with this disorder.

Robotic repair of a vesicovaginal fistula in an irradiated field using a dehydrated amniotic allograft as an interposition patch.

Project description:We report the case of a 66 year old female with a supratrigonal vesicovaginal fistula (VVF) that developed after undergoing radical hysterectomy, chemotherapy and pelvic radiation therapy for advanced cervical cancer. VVF repairs in an irradiated field are known to be complicated procedures with significant morbidity and a high rate of failure due to the effect of radiation. Amniotic membranes have been demonstrated to improve healing rates in difficult to heal wounds. To decrease morbidity a minimally invasive robotic procedure was performed and a dehydrated amniotic allograft patch was used to augment tissue healing. The VVF was repaired using the da Vinci Surgical System and the amniotic membrane was used as an interposition patch over the repair. There were no operative or postoperative complications and the patient was discharged home on postoperative day one. A cystogram performed 3 weeks postoperatively demonstrated a healed fistula. Follow-up at 5 months revealed no incontinence. This is the first reported case of a robotic VVF repair performed in an irradiated pelvis and the first use of an amniotic membrane allograft in the repair a VVF.

The Latzko: A high-value, versatile vesicovaginal fistula repair.

Project description:The Latzko transvaginal vesicovaginal fistula repair is a highly effective treatment for even complex fistulae. Our video demonstrates the Latzko repair technique and its application in a variety of circumstances that include fistula management concurrent with treatment of uterovaginal prolapse, after complex urologic surgery, and in the postpartum setting after urologic injury. The technique of the procedure varies only slightly in these diverse conditions. The basic steps begin with hydro-dissecting the epithelium from the underlying fascia surrounding the fistula tract, followed by denuding the epithelium within a circumscribing incision around the fistula. The fistula is then closed with a purse-string suture placed just outside the epithelialized tract. Next, several layers of imbricating sutures are placed to close the defect. Finally, the vaginal epithelium is closed.

Rupture of the Left Renal Fornix after Vaginal Repair of Postpartum Vesicovaginal Fistula.

Project description:Surgical repair of vesicovaginal fistulas carries a risk of postoperative obstruction of the upper urinary tract. In the case described here, a postoperative intramural edema led to urinary retention and subsequent rupture of the renal pelvis. This is a rare but typical urological emergency. If patients complain postoperatively of flank pain, ultrasound should be carried out promptly. If the findings are unclear (no urinary retention despite clinical symptoms), additional computed tomography should be performed to determine whether rupture of the fornix has occurred.

Validation of an ovine vesicovaginal fistula model.

Project description:Introduction and hypothesisA representative, large animal model of vesicovaginal fistulas is needed for the training of surgeons and for the development of new surgical techniques and materials for obstetric fistula repair.MethodsThe safety, feasibility, and reproducibility of vesicovaginal fistula creation were studied in 4 adult female sheep. A 1-cm fistula was created between the vagina and the bladder through a transvaginal approach. The defect was allowed to heal for 8 weeks and the animals were then euthanized. The primary outcome was the fistula patency. Secondary outcomes were fistula size, urogenital dimensions, urodynamic evaluation, histology (inflammation, vascularization, collagen deposition) and biomechanical characteristics of the fistula edge (stress at break, maximum elongation, and stiffness).ResultsThe transvaginal creation of a vesicovaginal fistula was safe. All animals survived the surgical procedure and follow-up period, without complications. Three of the four animals demonstrated a patent vesicovaginal fistula after 8 weeks. Baseline data are provided of the urogenital dimensions and the urodynamic, histological, and biomechanical characteristics of the model.ConclusionsThe ewe is a safe, feasible, and reproducible model for vesicovaginal fistulas. The model can help to study new techniques and materials to boost surgical innovation for vesicovaginal fistula repair.

Continence, quality of life and depression following surgical repair of obstetric vesicovaginal fistula: a cohort study.

Project description:ObjectiveWe evaluated residual incontinence, depression, and quality of life among Malawian women who had undergone vesicovaginal fistula (VVF) repair 12 or more months previously.DesignProspective cohort study.SettingFistula Care Centre in Lilongwe, Malawi.PopulationWomen who had undergone VVF repair in Lilongwe, Malawi at least 12 months prior to enrolment.MethodsSelf-report of urinary leakage was used to evaluate for residual urinary incontinence; depression was evaluated with the Patient Health Questionnaire-9; quality of life was evaluated with the King's Health Questionnaire.Main outcome measuresPrevalence and predictors of residual incontinence, quality of life scores, and prevalence of depression and suicidal ideation.ResultsFifty-six women (19.3%) reported residual urinary incontinence. In multivariable analyses, predictors of residual urinary incontinence included: pre-operative Goh type 3 [adjusted risk ratio (aRR) 2.82; 95% confidence interval (CI) 1.61-5.27) or Goh type 4 1.08-2.78), positive postoperative cough stress test (aRR = 2.42; 95% CI 1.24-4.71) and the positive 1-hour postoperative pad test (aRR = 2.20; 95% CI 1.08-4.48). Women with Goh types 3 and 4 VVF reported lower quality of life scores. Depressive symptoms were reported in 3.5% of women; all reported residual urinary incontinence.ConclusionsWhile the majority of women reported improved outcomes in the years following surgical VVF repair, those with residual urinary incontinence had a poorer quality of life. Services are needed to identify and treat this at-risk group.Tweetable abstractNearly one in five women reported residual urinary incontinence at follow up, 12 or months after vesicovaginal fistula repair.

Surgical repair of hepatic hydrothorax caused by diaphragmatic fistula.

Project description:A 65-year-old woman visited our hospital complaining of dyspnea several days before admission. A chest X-ray showed massive right-sided pleural effusion, which was not observed 1 month previously. Although the patient had never been diagnosed with cirrhosis at regular visits, the patient was diagnosed with primary biliary cholangitis at admission. Hepatic hydrothorax was suspected because pleural effusion was transudative. A diaphragmatic fistula was confirmed and closed by thoracoscopy. Pleural effusion did not reappear after this procedure. Existence of a diaphragmatic defect should be confirmed under direct vision if pleural effusion accumulates acutely or becomes beyond control.

Laparoscopic appendicular interposition ureteroplasty for mid-ureteral defect.

Project description:Patients with ureteral defects and salvageable renal units present a challenge in reconstructive urology. Vermiform appendix interposition is an option in the management of mid-ureteral defects that can not be managed by primary ureteroureterostomy. Laparoscopic appendicular interposition ureteroplasty is a technically demanding and an infrequently attempted procedure. We present a video demonstration of laparoscopic appendicular interposition for a 4-cm long right mid-ureteral defect in an elderly male. Laparoscopic appendicular interposition ureteroplasty for mid-ureteral defects can provide good long-term functional outcomes with results comparable to an open approach and has the advantage of reduced morbidity.

Use of a postoperative pad test to identify continence status in women after obstetric vesicovaginal fistula repair: a prospective cohort study.

Project description:ObjectiveDetermine whether a 1-hour pad test at discharge can identify continence status within 120 days of obstetric vesicovaginal fistula (VVF) repair.DesignProspective cohort study.SettingFistula Care Centre in Lilongwe, Malawi.PopulationWomen with VVF who underwent repair between January 2012 and December 2014.MethodsData on demographics, obstetric history, physical exam findings, operative management, postoperative findings, and follow up evaluations were collected on women with VVF repair.Main outcome measuresSensitivity, specificity, positive and negative predictive values (PPV and NPV), and a receiver operating curve (ROC) were calculated to assess the utility of using a discharge pad test at three thresholds to identify women likely to be continent at follow up.ResultsAfter VVF repair, 346 women had a 1-hour pad test performed at the time of hospital discharge and completed follow up within 120 days of repair. Of these, 79.8% (n = 276) were completely continent, whereas 20.2% (n = 70) had some degree of incontinence. The sensitivity and specificity of a negative 1-hour pad test at predicting continence is 68.1% and 82.9%, respectively. With this prevalence, a negative pad test at a 1.5-g threshold demonstrates a high predictive value (PPV = 94.0%, 95% CI 90.0-96.9) in detecting women with continence after repair.ConclusionsAt the 1.5-g threshold, a negative pad test at discharge identifies 94% of women who will remain continent after VVF repair. Adding the pad test to fistula care can identify women who are likely to remain continent and may not need further therapies in settings where resources are limited and follow up after repair is difficult.Tweetable abstractA negative pad test after repair is associated with continued continence at follow up.
