Abstract
Objective: to determine the operative performance of chromohysteroscopy (HCC) in the evaluation of the endometrium at the San José Hospital in Bogotá DC, Colombia, between February and October 2014. Methodology: 97 adult women were included to whom 5 cc of blue was applied of 1% methylene in the endometrial cavity and by hysteroscopy the presence of dark spots from where directed biopsies were taken (gold standard) was determined. Using an excel sheet and stata13® database, operating characteristics were calculated by means of contingency tables, HCC and conventional hysteroscopy (HC) were compared using the McNemar test, and the agreement between evaluators and techniques was evaluated. average of the kappa coefficient. Results: the main indication was abnormal uterine hemorrhage (80.41%) performed in premenopausal women (78.35%) with age around 45 years who were overweight. The microscopy detected a case of endometrial cancer, one of endometrial hyperplasia and four of chronic endometritis. The sensitivity and negative predictive value of HCC was 100%, specificity 39.8% and PPV 1.7% for cancer and hyperplasia. For endometritis the sensitivity was 50%, specificity 38.9%, PPV 3.5% and NPV 94.6%. There were no statistical differences between CHC and HC. The agreement between evaluators was 79.12% and between techniques 54.64%. Conclusion: HCC in abnormal uterine hemorrhage can provide a higher performance for the diagnosis of malignant and premalignant pathologies than HC due to the high negative predictive value found. Abbreviations: CHC, chromohysteroscopy; HC, conventional hysteroscopy; HUA, abnormal uterine bleeding.
