RESUMEN
OBJECTIVE: This study aims to establish the postoperative success rates of midvaginal versus juxtacervical obstetric vesicovaginal fistula (VVF) repairs. In addition, we aim to quantify the impact of patient sociodemographic variables, fistula classification, and surgical repair techniques associated with postoperative outcomes. METHODS: A retrospective cohort study was conducted involving 420 women who had undergone a primary obstetric VVF repair. All data were collected from the Panzi Hospital, Democratic Republic of Congo between 2015 and 2017. Patient notes were analyzed to determine sociodemographic variables, symptoms, fistula classification, surgical repair techniques, and postoperative follow up. Binary logistic regression presented as χ2 for trend was used to establish P values. RESULTS: Overall, 95.6% and 96.2% of midvaginal and juxtacervical VVF, respectively, underwent a successful repair. The principal prognostic factor associated with a statistically significant likelihood of a successful repair was the degree of fibrosis noted preoperatively (P =0.004, 95% confidence interval [CI] 2.38-94.61). Furthermore, VVF were more likely to have a successful repair if they were closed in two layers (P = 0.004, 95% CI 1.86-25.81) and sutured vertically (P = 0.005, 95% CI 1.16-2.52). CONCLUSION: Overall, high postoperative success rates of obstetric VVF repair can be expected among well-trained surgeons but a complex interplay of factors means that the ability to preoperatively foreshadow individual outcomes remains difficult.

BACKGROUND: Obstetric fistula is a resultant effect of prolonged obstructed labour. The best surgical management of simple uncomplicated fistula determines the outcome of care. OBJECTIVE: To compare outcome of uncomplicated mid-vaginal fistula between vaginal and abdominal route of repair. MATERIALS AND METHOD: This was a hospital based retrospective study conducted at the University College Hospital, Ibadan from January, 2000 till December, 2006. RESULT: Of the 71 midvaginal fistulae managed, 40.8% had abdominal repair while the remainder were through vaginal approach. The overall repair success rate was 79.2% with comparable outcome in both groups-78.3% for the abdominal and 80% for the vaginal group (p=0.999). The duration of hospital stay did not differ significantly between the groups (p=0.972). Post operative complications were found in 41.4% of the abdominal group compared to none in the vaginal group (p<0.001). The complications were failed repair (20.7%) and urinary tract infection (20.7%). The mean estimated blood loss was 465.5ml in the abdominal group compared to 332.9ml for the vaginal group (p=0.303). CONCLUSION: Despite the comparable surgical repair outcome of the two methods, the vaginal approach is associated with lesser blood loss and lower risk of post-operative complications. It is recommended that the vaginal route should be employed in the repair of uncomplicated midvaginal fistula unless there are other compelling reasons to the contrary.
