Abstract

The purpose of this prospective study was to investigate whether office hysteroscopy (OH) can be used to assess the mechanisms of action of progestogen-only contraceptives (POCs), diagnose possible local causes of abnormal uterine bleeding (AUB), and support the treatment plan of symptomatic patients using POCs compared with those who do not use hormones. The study included 140 women who were divided into two groups. Group A consisted of 70 women who used POCs, whereas group B consisted of 70 women who did not use hormones. They were successively examined using transvaginal ultrasonography (TVS), OH, and endometrial sampling. The TVS results were consistent with those of OH and histopathology. The changes in endometrial thickness and vasculature, as well as fallopian tube (FT) functions, were significantly more pronounced in POC users than in non-POC users. There was a significant reduction in the peristalsis of the proximal part of the FT, as well as a reduction in the bubble flow test in group A compared with group B. In addition, the combination of peristalsis and the bubble flow test (Darwishscope test) was significantly lower in group A. It was concluded that using OH as a simple diagnostic tool in women with POCs would contribute to a better understanding of the mechanisms of endometrial and FT effects and explain some local endometrial causes of AUB. This ensures that the combination of TVS and OH would limit routine endometrial sampling in POCs users.
