Hysteroscopy is an in-office or hospital outpatient procedure designed to look into the uterus through the natural opening of the cervix. The cervix may need to be dilated to accommodate the 5mm fiber optic scope which provides a channel to infuse saline to distend the uterus, as well an outside light source and the returning light for viewing. The scope is attached to a small video camera which allows the findings to be viewed on a video screen. The hysteroscope can be used to facilitate operations through the cervix, such as polypectomy, endometrial ablation or placement of tubal occlusion devices such as the Essure. Small polyps or fibroids can sometimes be removed directly through the hysteroscope by hysteroscopic resection. Recovery from hysteroscopic procedures is typically minimal, returning to full activity the next day.
