Measuring the cost-effectiveness of treating rectovaginal and vesicovaginal fistulas: A multicenter global study by the Fistula Foundation.

OBJECTIVE: Surgery for obstetric fistula is a highly effective treatment to restore continence and improve quality of life. However, a lack of data on the cost-effectiveness of this procedure limits prioritization of this essential treatment. This study measures the effectiveness of fistula surgeries using disability-adjusted life years (DALYs) averted. METHODS: In 2021 and 2022, the Fistula Foundation funded 20 179 fistula surgeries and related procedures at 143 hospitals among 27 countries. We calculated DALYs averted specifically for vesicovaginal fistula and rectovaginal fistula procedure types (n = 13 235 surgeries) by using disability weights from the 2019 Global Burden of Disease study. We based cost calculations on direct treatment expenses, including medical supplies, health provider fees, and preoperative and postoperative care. We measured effectiveness using data on the risk of permanent disability, country-specific average life spans, and treatment outcomes. RESULTS: The total treatment cost was $7.6 million, and a total of 131 433 DALYs were averted. Thus, the cost per DALY averted-the cost to restore 1 year of healthy life-was $58. For this analysis, we took a cautious approach and weighted only surgeries that resulted in a closed fistula with restored continence. We calculated DALYs averted by country. Limitations of the study include data entry errors inherent in patient logs and lack of long-term outcomes. CONCLUSION: The current study demonstrates that obstetric fistula surgery, along with having a significant positive impact on maternal health outcomes, is highly cost-effective in comparison with other interventions. The study therefore highlights the benefits of prioritizing fistula treatment as part of the global agenda for maternal health care.

Surgical Simulation of Posterior Sagittal Anorectoplasty for Rectovestibular Fistula: Low-Cost High-Fidelity Animal-Tissue Model.

PURPOSE: To provide a high-fidelity, animal tissue-based model for the advanced surgical simulation of a Posterior Sagittal Anorectoplasty (PSARP) for rectovestibular fistula in anorectal malformation (ARM). MATERIALS AND METHODS: A chicken cadaver was used to assess the feasibility of simulating a PSARP for rectovestibular fistula in ARM. No modification was required to implement the surgical simulation. RESULTS: A detailed description of the high-fidelity surgical simulation model is provided. The PSARP can be simulated while providing realistic anatomy (e.g. common wall between rectovestibular fistula and vagina), adequate rectal size, location and placement of the rectovestibular fistula, and proximity to the vagina. Haptic conditions of the tissue resemble human tissue and operative conditions as well. DISCUSSION: Concerning the decreased exposure of index cases of pediatric surgical trainees and pediatric surgeons in practice, simulation-based training can provide means to acquire or maintain the necessary skills to perform complex surgical procedures [1-5] Surgical simulation models for ARM are limited. Few low-cost trainers are available with predominant artificial and mostly unrealistic tissue [6-8] Animal models have the advantage of realistic multilayer tissue haptic feedback [6]. CONCLUSION: We provide a low-cost, high-fidelity model for correcting a rectovestibular fistula in a child with ARM, a complex operative procedure with low incidence but high-stake outcomes. The described tissue model utilizing the chicken cloaca anatomy provides a high-fidelity model for operative correction of rectovestibular ARM. For simulation purposes in the treatment of ARM, this model appears to be promising in terms of providing realistic pathology and haptic feedback in pediatric dimensions. LEVEL OF EVIDENCE: V.

[Psycho-social and economic reintegration of women operated for urogenital fistula]. / Réinsertion psycho-sociale et économique des femmes opérées pour fistules obstétricales et non obstétricales au Congo.

OBJECTIVE: To study the psycho-social and economic reintegration of women operated for genital fistula in Congo. MATERIAL AND METHODS: This was a descriptive observational study conducted in Brazzaville and Ewo, Republic of Congo, from April 1 to October 31, 2018. It included patients operated for genital fistula between 2008 and 2017. Variables of interest were socio-demographic, reproductive and clinical characteristics. The analysis was performed using the SPSS 20 software. RESULTS: The overall, 34 patients were studied, with age ranging from 29 to 65 years old with a median of 43 (39, 50) year. The context of fistula occurrence was obstetrical in 24 women (70%). The Practice of an income-generating activity before, during and after fistula was 76%; 32% and 64% (P=0.0007). Concerning the psychological status, in these women, self-esteem went from 26% to 73% (P=0.0003) and the prevalence of suicidal thoughts went from 29% before fistula treatment to 0% after (P=0.0009). The tendency to isolate themselves went from 44% before fistula cure to 3% after (P=0.00008). With regards to reproductive life, 54% of women had no desire for maternity and 17% did not have a desire of sexual intercourse. Only 26% of women benefited from the psychologist. Support. CONCLUSION: In this series, we observed a resumption of income-generating activities in women operated for a treatment of urogenital fistula and a psychological recovery with an increase in self-esteem and a decrease in suicidal thoughts.

Obstetric Fistula Repair in Sub-Saharan Africa: Partnering to Create Sustainable Impact for Patients and Trainees.

Obstetric fistula, an abnormal connection between a woman's genital tract and urinary tract or rectum, can be physically and psychosocially debilitating. We describe a sustainable obstetric fistula surgical trip model that includes providers from Women and Infants Hospital at Brown University. These surgical trips provide pre-operative, surgical, and post-operative care to patients with fistulae at Kibagabaga Hospital in Kigali, Rwanda. To ensure patients are prepared for the recovery process after fistula surgery, the team created a post-operative education curriculum that includes illustrative visual aids and teaching guides translated into Kinyarwanda, focusing on topics including urinary catheter care, wound care, and pain management. Through this program, the team is committed to restoring women's dignity through fistula repair as well as providing a model for delivery of sustainable surgical care in low-resource settings. Involvement of trainees into a global health team like this can benefit both the trainee and the patients served.

Estimating the cost and cost-effectiveness for obstetric fistula repair in hospitals in Uganda: a low income country.

In Africa, about 33 000 cases of obstetric fistula occur each year. Women with fistula experience debilitating incontinence of urine and/or faeces and are often socially ostracized. Worldwide, Uganda ranks third among countries with the highest burden of obstetric fistula. Obstetric fistula repair competes for scarce resources with other healthcare interventions in resource-limited settings, even though it is surgically efficacious. There is limited documentation of its cost-effectiveness in the most affected settings. We therefore sought to assess the cost-effectiveness of surgical intervention for obstetric fistula in Uganda so as to provide appropriate data for policy-makers to prioritize fistula repair and reduce women's suffering in similarly burdened countries. We built a decision-analytic model from the perspective of Uganda's National Health System to estimate the cost-effectiveness of vesico-vaginal and recto-vaginal fistula surgery vs a competing strategy of no surgery for Ugandan women with fistula. Long-term disability outcomes were assessed based on a lifetime Markov state-transition cohort and effectiveness of surgery. Surgical costs were estimated by micro-costing local Ugandan health resources. Disability weights associated with vesico-vaginal, recto-vaginal fistula and mortality rates among the general population in Uganda were based on published sources. The cost of providing fistula repair surgery in Uganda was estimated at $378 per procedure. For a hypothetical 20-year-old woman, surgery was estimated to decrease the lifetime disability burden from 8.53 DALYs to 1.51 DALYs, yielding a cost per DALY averted of $54. The results were robust to variations in model inputs in one-way and probabilistic sensitivity analyses. Surgery for obstetric fistula appears highly cost-effective in Uganda. In similar low-income countries, governments and non-governmental organizations need to prioritize training and strengthening surgical capacity to increase access to fistula surgical care, which would be an important step towards achieving universal health coverage.

Contraception knowledge and practice among fistula patients at referral centers in Kenya.

OBJECTIVE: To establish knowledge and practice of contraception among patients presenting with a fistula attending fistula care services at 4 centers in Kenya. METHODS: In a descriptive cohort study carried out between January and December 2011, patients presenting with a history of urine and/or stool leakage were screened and those with confirmed diagnosis of fistula were assessed and prepared for surgery. Informed consent was obtained from study participants before surgical intervention. After surgery, a standard questionnaire was used to collect information on sociodemographics, duration of leakage, and reproductive health practices. RESULTS: A total of 206 patients were interviewed. Most of the patients were young (mean age 22 years). Literacy was low: only 1.7% reported tertiary-level education, and 56.7% reported primary-level education. With regard to family planning, 76.2% of patients expressed a willingness to use contraception after fistula repair. CONCLUSION: Among patients presenting with a fistula in Kenya, the unmet need for family planning was high. There is an urgent need for healthcare providers to integrate family planning services in fistula care programs.

Obstetric fistula in 14,928 Ethiopian women.

OBJECTIVES: Obstetric fistulas are severe sequelae of prolonged obstructed labor, a widespread but incompletely documented problem of low-income countries. Here, we characterize women with obstetric fistula, test the hypothesis that primi- and multipara represent different profiles and that fetal size is an important factor in developing fistula. DESIGN: Hospital registry statistics and questionnaire. POPULATION: A total of 14,928 Ethiopian women with obstetric fistula in 1974-2006 and 434 admitted in 2007-8. METHODS: Self-reported age, marital status, education, distance from home to health facility, parity, duration of labor, neonatal outcome and sex, lag time to treatment; measurement of weight, stature, extent of lesion and clinical assessment of continence before hospital discharge. OUTCOME MEASURES: Duration of labor, extent of pelvic injury and neonatal survival, cure rate. RESULTS: Primi- were more common than multiparous cases (56.8 vs. 43.2%). They were of similar age at marriage (17 years) and stature at hospital admission, but shorter than the population average (152.7 vs. 156.5 cm). Primipara had longer labor than multipara (50.5% > 3 days vs. 27%), larger uro-vaginal fistula, more stillbirths (95 vs. 88%), recto-vaginal fistula, vaginal scarring, persistent incontinence after repair and were more commonly divorced. Male fetuses were involved in 76.7% of obstructed deliveries but in only 44.6% of a previous uneventful delivery in multipara. Educational attainment positively influenced outcomes. CONCLUSIONS: Obstetric fistula is more commonly associated with primiparous than subsequent pregnancies. Primipara have a longer and more damaging labor. A causative role for cephalo-pelvic disproportion is supported by the observation that male fetuses are more commonly involved in obstructed labor.

Assessment of the efficacy of the rectovaginal button fistula plug for the treatment of ileal pouch-vaginal and rectovaginal fistulas.

BACKGROUND: The treatment of rectovaginal and ileal pouch-vaginal fistulas remains a challenging problem for the colorectal surgeon. The aim of this study was to assess the short-term efficacy of the new Surgisis Biodesign rectovaginal button fistula plug in patients with such fistulas. METHODS: Between May 2008 and September 2008, patients with confirmed rectovaginal and ileal pouch-vaginal fistulas with backgrounds of inflammatory bowel disease were treated with the button fistula plug. The fistulas were assessed by magnetic resonance imaging and/or examination under anesthesia before the procedure. RESULTS: Twelve patients with a median age of 36 (range, 29-42) years underwent a total of 20 plug insertions. Five patients had confirmed rectovaginal fistulas and seven patients had ileal pouch-vaginal fistulas. At a median follow-up of 15 (interquartile range, 10-21) weeks, 7 of 12 patients (58%) had been treated successfully. Seven of the 20 plugs that were inserted (35%) were successful. This equates to the successful treatment of three of five (60%) of the rectovaginal fistulas, and four of seven (57%) of the ileal pouch-vaginal fistulas. Of the six patients who initially failed, a repeat procedure was performed of which one was successful. Two patients underwent a third repeat procedure, which was again unsuccessful in both cases. The success rate of these eight repeat plug insertions was therefore 12.5%. All plug failures were the result of dislodgement of the plug. There was no morbidity in our series. CONCLUSIONS: The new button fistula plug successfully treated 7 of 12 (58%) rectovaginal and ileal pouch-vaginal fistulas.

Complex obstetric fistulas.

Obstetric fistulas are rarely simple. Most patients in sub-Saharan Africa and parts of Asia are carriers of complex fistulas or complicated fistulas requiring expert skills for evaluation and management. A fistula is predictably complex when it is greater than 4 cm and involves the continence mechanism (the urethra is partially absent, the bladder capacity is reduced, or both); is associated with moderately severe scarring of the trigone and urethrovesical junction; and/or has multiple openings. A fistula is even more complicated when it is more than 6 cm in its largest dimension, particularly when it is associated with severe scarring and the absence of the urethra, and/or when it is combined with a recto-vaginal fistula. The present article reviews the evaluation methods and main surgical techniques used in the management of complex fistulas. The severity of the neurovascular alterations associated with these lesions, as well as inescapable limitations in staff, health facilities, and supplies, make their optimal management very challenging.
