The first-line investigation of postmenopausal bleeding: transvaginal ultrasound scanning and endometrial biopsy may be enough.

Postmenopausal bleeding is a common problem in clinical practice with significant implications; however, the diagnostic strategies often vary among different centers. In the recent years, there was a trend to adopt less invasive procedures without compromising efficacy and safety. There is continuous debate about the different available modalities for investigation, and a large number of studies were conducted to define their roles. Some authors recommended that hysteroscopy should be the standard investigation procedure for women with postmenopausal bleeding. Nonetheless, there is a strong evidence to suggest that transvaginal ultrasound scanning, with or without endometrial biopsy, is a safe and more cost-effective initial tool in investigating these women. This commentary highlights this important issue and discusses the role of these different modalities.
