Final answer:
The procedure that uses an optical magnifying instrument to examine the vagina and cervix is called a Colposcopy. It is especially used in the case of abnormal Pap smear results to detect cervical cancer and other diseases.
Step-by-step explanation:
The procedure that examines the vagina and cervix using an optical magnifying instrument is known as a Colposcopy. This medical diagnostic procedure is performed to closely inspect the cervix, vagina, and vulva for signs of disease. In a Colposcopy, a colposcope — a special kind of microscope designed for this purpose — is used to illuminate and magnify the structures of the cervix and vagina. It's often conducted if a Pap smear result is abnormal and can be instrumental in detecting cervical cancer and other conditions. Other procedures mentioned, such as Laparoscopy, involve the use of a camera inserted through the abdominal wall to inspect the abdomen or other internal organs, which is different from a Colposcopy.
