Objective:To determine the diagnostic accuracy of the Ianieri Hysteroscopic Risk scoring system (IHRSS) in the diagnosis of endometrial hyperplasia and endometrial carcinoma among Filipino women who underwent hysteroscopy for abnormal uterine bleeding and thickened endometrium in a tertiary hospital

Patients and Methods:This is a cross-sectional study (chart review) of patients who underwent hysteroscopy for abnormal uterine bleeding and thickened endometrium in a tertiary hospital from Aprill 2015-December 2017. Hysteroscopic videos were viewed and scored according to the Ianieri Hysteroscopic Risk Scoring System (IHRSS) and compared to histopathologic reports. Sensitivity, specificity, Positive and Negative Predictive Values were computed for 4 categories: 1) Normal Endometrium (NE); 2) Non-Atypical Hyperplasia (EH); 3) Atypical Hyperplasia (AEH); and 4) Endometrial Carcinoma (EC).

Results:This paper showed showed a sensitivity and specificity of 94.6% and 82.5% for NE; 66.7% and 98.4% for EH; 100% and 98.4% for AEH; and 100% and 100% for EC. The positive predictive values and negative predictive values were 96.5% and 75% for NE, 63.6% and 96.5% for EH, 57.4% and 100% for AEH, and 100% and 100% for EC.

Conclusion:The IHRSS showed good diagnostic accuracy in diagnosing endometrial carcinoma and hyperplasia among patients who presented with abnormal uterine bleeding. This may prove to be a good diagnostic tool for hysteroscopists and may aid in intraoperative clinical and surgical judgment.
