Summary
Hysteroscopic endometrial biopsy is one of the most common procedures in gynecology. For patients with atrophic or hypotrophic endometrium, typical of menopausal women, the "chip biopsy" technique is often preferred as it provides adequate tissue samples for accurate histological examination. Recently, the "rail biopsy" technique has also been adopted at IRCCS AOUBO for biopsies in similar cases. Currently, the choice between these techniques depends largely on operator preference and experience, as there is no strong evidence favoring one over the other in terms of efficacy, safety, or tolerability. This observational, single-center, cross-sectional, prospective, non-profit study aims to compare the procedure duration of "chip biopsy" versus "rail biopsy" in patients requiring endometrial biopsy of atrophic or hypotrophic endometrium. The study is expected to last approximately 14 months. Approximately 156 patients will be enrolled.
