Diagnostic Hysteroscopy Diagnostic hysteroscopy is a commonly performed gynecologic procedure to evaluate the endometrial cavity. This article focuses on the procedure of diagnostic hysteroscopy. Broadly, 2 systems of diagnostic hysteroscopy exist: panoramic (also known as direct optical) and contact (also known as contact microhysteroscopy). Modern references to hysteroscopy usually imply a panoramic technique in which the uterine cavity is distended with liquid or gas and evaluated with the hysteroscope Diagnostic Laparoscopy Exploratory laparoscopy (also referred to as diagnostic laparoscopy) is a minimally invasive method for the diagnosis of intra-abdominal diseases through direct inspection of intra-abdominal organs. Exploratory laparoscopy also allows tissue biopsy, culture acquisition, and a variety of therapeutic interventions. Laparoscopic ultrasonography (LUS) can also be performed during exploratory laparoscopy to evaluate organs that are not amenable to direct visual inspection.
