Modern operative hysteroscopy.

Hysteroscopy is an endoscopic surgical procedure that has become an important tool to evaluate intrauterine pathology. It offers a direct visualization of the entire uterine cavity and provides the possibility of performing biopsy of suspected lesions that can be missed by dilatation and curettage (D&C). In most cases, the intrauterine pathologies can be diagnosed and treated at the same setting as office hysteroscopy ("see and treat approach"). For example, endometrial polyps can be diagnosed and removed; similarly, intrauterine adhesions can be liberated in the outpatient setting without the need for an operating theatre. Today, many hysteroscopic procedures can be performed in the office or outpatient setting. This is due to the feasibility of operative hysteroscopy using saline as a distending medium, the vaginoscopic approach of hysteroscopy and the availability of mini-hysteroscopic endoscopes. There is good evidence to suggest that hysteroscopy in an ambulatory setting is preferable for the patient, and that it avoids complications, allows a quicker recovery time and lowers cost. Advances in technology have led to miniaturization of high-definition hysteroscopes without compromising optical performance, thereby making hysteroscopy a simple, safe and well-tolerated office procedure. The new surgical technology such as bipolar electrosurgery, endometrial ablation devices, hysteroscopic sterilization, and morcellators has revolutionized this surgical modality. The modern development of hysteroscopy completely transformed the approach to the uterine intracavitary pathologies moving from a blind procedure under general anesthesia to an outpatient procedure performed under direct visualization, offering therapeutic and irreplaceable possibilities of treatment that should belong to every modern gynecologist.
