Hysteroscopy is a simple procedure to visualize the cervical canal and the inside of the uterus using a thin, lighted, flexible tube designated a hysteroscope. The device is inserted through the vagina and can be used as a diagnostic, as well as a therapeutic tool. The procedure can be performed without a local anesthetic, especially if it is used for diagnostic procedures only. Local anesthetic if used, is usually to remove a polyp, fibroid, adhesions or for biopsy.
