Accuracy of intraoperative consultation for ovarian tumours: Experience in an Indonesian teaching hospital

Background: Ovarian tumours are a very heterogeneous group of tumours, consisted of non-neoplastic and neoplastic lesions. Preoperative diagnoses in most conditions are inconclusive due to similar clinical, radiological and laboratory findings. Intraoperative consultation is crucial because it can provide rapid diagnosis leading to a suitable surgical management for the patients. Objective: To obtain profile, accuracy and concordance rates of ovarian intraoperative consultation in Dr. Soetomo Hospital Surabaya, a teaching hospital in Indonesia. Materials and Methods: Observational retrospective study, using data from archives of intraoperative consultation reports in Dr. Soetomo General Hospital Surabaya within 2012-2016 period. There were 734 cases of ovarian intraoperative consultations, all then proceed to permanent sections. Accuracy, sensitivity, and specificity rates were calculated. Results: Overall accuracy was 89.5%. Sensitivity for benign, borderline and malignant cases were 98.49%, 71.19% and 84.01%, respectively. Specificity were 90.32%, 95.11% and 98.72%, respectively. Conclusion: Intraoperative consultation for ovarian tumours has a reliable diagnostic value in benign and malignant lesion, but lower value in borderline tumours.
