Innovations in hysteroscopic surgery: expanding the meaning of "in-office".

Surgical innovations in hysteroscopic surgery have radically changed the way of treating intrauterine pathologies, throughout the advent of the 'see-and-treat' philosophy, which transferred the advantages of inpatient surgery to the office setting. However, in-office operative hysteroscopy was mainly limited to minor pathology as a supplement to its diagnosis, whereas commonly larger abnormalities were left to be treated in the operating room. Nowadays, pre-surgical assessment of uterine pathology is based on modern ultrasound evaluation and the evolving role of in-office hysteroscopy as a well-planned treatment modality for larger lesions and more complex procedures. Office operative hysteroscopy has been accepted as a feasible, cost-effective, practical way to treat almost any intrauterine disease. Despite the growing role of other imaging tools in the proper evaluation of benign uterine diseases, especially extended beyond to direct hysteroscopic visualization, diagnostic hysteroscopy remains a valuable tool of direct endometrial sampling and may be used as the first line in the diagnosis of endometrial cancer and hyperplasia. Our aim is to describe the most recent innovations and future perspectives in the field of outpatient operative hysteroscopy: mini-resectoscopes, intrauterine morcellators, tissue retrieval systems, diode laser, new miniaturized mechanical instruments, endometrial ablation devices and portable and entry-level hysteroscopes.
