Diagnostic hysteroscopy is a gynecologic procedure to evaluate the uterine cavity, endocervical canal and the tubal ostia. This procedure is often coupled with a laparoscopy and an endometrial biopsy.
There are two techniques of performing a diagnostic hysteroscopy
Panoramic hysteroscopy involves distention of the uterine cavity with liquid (or gas occasionally) and evaluation with the hysteroscope. Contact hysteroscopy does not involve use of distention media.The hysteroscope is passed directly into the uterus and placed in gentle contact with the endometrial lining to obtain a magnified view. Only tissue that is in direct contact with the distal tip can be inspected and evaluated 1, This technique is time consuming and associated with high rates of uterine perforation.
