Abstract
Introduction: Rectovaginal fistula (RVF) is a complex debilitating condition that results from several etiologies, obstetric trauma being the most common. Occasionally RVF closure is non-successful. The objective of this study is to develop a predictive score to identify predictors of failure of surgical closure of obstetric RVF (FSCORVF) in the Democratic Republic of the Congo.
Methods: This was an analytical cross-sectional study conducted on 268 patients with obstetric RVF who have received surgical management. We proceeded with a bivariate and then multivariate analysis. Score discrimination was assessed using the ROC curve and C-index and score calibration was done according to the Hosmer-Lemeshow test.
Results: Surgical closure of RVF failed in 12.31% of cases (33/268). After logistic modelling, five criteria emerged as predictive factors of FSCORVF (LUSSY Score): the presence of moderate/severe fibrosis (aOR: 36.25; 95% CI: 1.88-699.37), combined RVF with other type of fistula (aOR: 61.41; 95% CI: 8.78-429.72), fistula size > 3 cm (aOR: 82.45; 95% CI: 10.48-648.58), per-operative hemorrhage (aOR: 27.84;; 95% CI: 5.08-152.47) and postoperative infection (aOR: 1161.35; 95% CI: 46.89-28765.47). A score of 0 to 22 was obtained with a value ≤ 9 points indicating a low risk of FSCORVF, a value between 10 and 12 defining a moderate risk and the value ≥ 13 points corresponding to a high risk of FSCORVF. The area under the ROC curve of the score is 0.9744 with a sensitivity of 90.91%, a specificity of 97.87%, a positive predictive value of 85.71% and a negative predictive value of 98.71%.
Conclusion: This study identified predictive factors for FSCORVF in the DRC, grouped in the LUSSY score. Complex fistulas (fistula size > 3 cm, severe fibrosis, combined fistulas) require advanced surgical routes different from the transvaginal and the transperineal ones used in the present study. Prevention of intraoperative hemorrhage and postoperative infections requires rigorous preparation, appropriate antibiotic prophylaxis, and strict postoperative follow-up.
期刊介绍:
Reproductive Health focuses on all aspects of human reproduction. The journal includes sections dedicated to adolescent health, female fertility and midwifery and all content is open access.
Reproductive health is defined as a state of physical, mental, and social well-being in all matters relating to the reproductive system, at all stages of life. Good reproductive health implies that people are able to have a satisfying and safe sex life, the capability to reproduce and the freedom to decide if, when, and how often to do so. Men and women should be informed about and have access to safe, effective, affordable, and acceptable methods of family planning of their choice, and the right to appropriate health-care services that enable women to safely go through pregnancy and childbirth.
