Predictive factors for emergent surgical intervention in patients with ovarian endometrioma hospitalized for pelvic inflammatory disease: A retrospective observational study

AimThe aim of this study was to identify predictive factors for emergent surgical interventions in patients with ovarian endometriomas hospitalized for pelvic inflammatory disease (PID). MethodsWe retrospectively identified 22 patients with ovarian endometriomas who were hospitalized to manage PID. Patients were divided into two groups: those who required emergent surgery after failed antibiotic therapy (emergent surgery group, n=6) and those who were discharged with successful antibiotic therapy (conservative group, n=16). Logistic regression analysis was performed to analyze the factors associated with emergent surgery. ResultsPatients in the emergent surgery group were significantly more likely to have intrauterine or intrapelvic procedures before the onset of PID compared to those in the conservative group (83% vs 38%, odds ratio 8.33, 95% confidence interval 1.02-181.3; P=0.048). The mean interval between the onset of PID symptoms and the commencement of parenteral antibiotic therapy was significantly longer in the emergent surgery compared to the conservative group (6.5 vs 1day, odds ratio 1.28, 95% confidence interval 1.01-1.75; P=0.041). ConclusionA history of an intrauterine or intrapelvic procedure before the onset of PID was more likely to result in emergent surgery. A longer interval between the onset of PID symptoms and the commencement of parenteral antibiotics was also associated with emergent surgery. These findings could help to identify patients with ovarian endometriomas hospitalized with PID at higher risk of emergent surgical intervention.
