Müllerian duct anomalies are a broad and complex spectrum of abnormalities that are often associated with infertility, obstetric complications as well as gynecological disorders among women of reproductive age. Operative hysteroscopy is the gold standard in the treatment of most of those anomalies amenable to surgical correction. The evidence to date shows an ongoing increase in the release of recommendations in favour of operative hysteroscopic treatment, in concert with the progressive refinement of hysteroscopic technologies and techniques. The aim of this paper was to describe and critically evaluate the role of the currently available hysteroscopic techniques for treating Müllerian duct anomalies, taking into account their indications, feasibility and efficacy as well as their impact on the reproductive outcome. Special attention will be paid to the most recently developed minimally invasive treatments for uterine and vaginal anomalies.
