ABSTRACT
Objective: Endometrial carcinoma is the most common gynaecological malignancy. Approximately 80% of endomentrial carcinoma occur in post-menopausal women. Present study aimed to evaluate the role of transvaginal ultrasonography and colour flow imaging in diagnosing endometrial pathologies especially endometrial carcinoma and later its confirmation by histopathology. Methods: 38 women presenting with history of at least 6 months amenorrhoea followed by bleeding per vaginum were included in the study. Transvaginal colour Doppler (TVS) followed by fractional curettage was done in all cases and cervical biopsy was done in selected cases. Uterine size, endometrial thickness and blood flow indices (RI, PI) were measured. Analysis of data was done using ‘z’ test and ‘t’ test. Results: Out of 38 women maximum number of cases (39.47%) were between 50 – 55 years. Using 4 mm of endometrial thickness as cut off value for discriminating normal and abnormal endometrium, sensitivity, specificity, PPV and NPV were 94.12%, 50%, 95.12% and 50% respectively (p < 0.05). No case of endometrial carcinoma was detected when the endometrium was <4 mm, making the sensitivity as 100%, NPV 100%, specificity 13.33% and PPV 23.53%. Using RI = 0.81 as cut off value for discriminating benign and malignant endometrium, sensitivity was 62.5%, specificity 53.33%, PPV – 26.3% and NPV as 84.2%. Conclusion: Transvaginal sonographic (TVS) evaluation of endometrial thickness (ET) is a reliable method of screening women with post-menopausal bleeding. Conservative approach may be offered to women showing ET of less than 4 mm and high impedance to flow in uterine and endometrial vessels.
