Pregnancy and childbirth after repair of obstetric fistula in sub-Saharan Africa: Scoping Review.

OBJECTIVE: To synthesise the evidence on pregnancy and childbirth after repair of obstetric fistula in sub-Saharan Africa and to identify the existing knowledge gaps. METHODS: A scoping review of studies reporting on pregnancy and childbirth in women who underwent repair for obstetric fistula in sub-Saharan Africa was conducted. We searched relevant articles published between 1 January 1970 and 31 March 2016, without methodological or language restrictions, in electronic databases, general Internet sources and grey literature. RESULTS: A total of 16 studies were included in the narrative synthesis. The findings indicate that many women in sub-Saharan Africa still desire to become pregnant after the repair of their obstetric fistula. The overall proportion of pregnancies after repair estimated in 11 studies was 17.4% (ranging from 2.5% to 40%). Among the 459 deliveries for which the mode of delivery was reported, 208 women (45.3%) delivered by elective caesarean section (CS), 176 women (38.4%) by emergency CS and 75 women (16.3%) by vaginal delivery. Recurrence of fistula was a common maternal complication in included studies while abortions/miscarriage, stillbirths and neonatal deaths were frequent foetal consequences. Vaginal delivery and emergency C-section were associated with increased risk of stillbirth, recurrence of the fistula or even maternal death. CONCLUSION: Women who get pregnant after repair of obstetric fistula carry a high risk for pregnancy complications. However, the current evidence does not provide precise estimates of the incidence of pregnancy and pregnancy outcomes post-repair. Therefore, studies clearly assessing these outcomes with the appropriate study designs are needed.

A framework for analyzing the determinants of obstetric fistula formation.

Obstetric fistula, a devastating complication of prolonged obstructed labor, was once common in the Western world but now occurs almost exclusively in resource-poor countries. Although much has been written about the surgical repair of obstetric fistulas, prevention of fistulas has garnered comparatively little attention. Because obstetric fistulas result from obstructed labor (one of the common causes of maternal death in impoverished countries), this study assesses the obstetric fistula problem using a framework originally developed to analyze the determinants of maternal mortality. The framework identifies and explicates three sets of determinants of obstetric fistulas: the general socioeconomic milieu in which such injuries occur (the status of women, their families, and their communities); intermediate factors (health, reproductive status, and use of health care resources); and the acute clinical factors that determine the ultimate outcome of any particular case of obstructed labor. Interventions most likely to work rapidly in fistula prevention are those that have a direct impact on acute clinical situations, but these interventions will only be effective when general socioeconomic and cultural conditions promote an enabling environment for health care delivery and use. Sustained efforts that impact all three levels of determining factors will be necessary to eradicate obstetric fistula.

Outcome of surgery for colovesical and colovaginal fistulas of diverticular origin in 40 patients.

INTRODUCTION: According to literature, colonic resection with a primary anastomosis and no defunctioning ileostomy is a safe treatment for colovesical or colovaginal fistula of diverticular origin. This study investigates the outcome of surgery for this patient group in a regional hospital. METHODS: Patients were obtained from a prospective database in the period 2004-2011. Several variables were investigated for their relation with surgical outcome. RESULTS: A colovesical (n = 35) or colovaginal (n = 5) fistula was diagnosed in 18 men and 22 women. The mean age was 69 years (range, 45-90). A rectosigmoid resection with primary anastomosis was performed in 32 patients. Fourteen patients received a defunctioning ileostomy. Eight patients were treated with a Hartmann procedure. Overall 30-day treatment-related morbidity and mortality was 48 and 8 %, respectively. Major morbidity, because of anastomotic leakage, was mainly observed in the primary anastomosis group without a defunctioning ileostomy. Morbidity and mortality were associated with high body mass index, diabetes, use of corticosteroids, and American Society of Anesthesiologists classification, though not significantly. CONCLUSIONS: One should be liberal in the use of a defunctioning ileostomy in case of a primary anastomosis after colonic resection for a diverticular fistula, in order to prevent high morbidity rates due to anastomotic leakage.
