An endoscopy is a procedure in which your doctor uses specialized instruments to view and operate on the internal organs and vessels of your body. It allows surgeons to view problems within your body without making large incisions.
A surgeon inserts an endoscope through a small cut, or an opening in the body such as the mouth. An endoscope is a flexible tube with an attached camera that allows your doctor to see. Your doctor can use forceps (tongs) and scissors on the endoscope to operate or remove tissue for biopsy.
An endoscope’s lighted camera allows your doctor to view potential problems without a large incision. A screen in the operating room lets the doctor see exactly what the endoscope sees. An endoscopic biopsy involves using forceps in an endoscope to remove a small sample of tissue. They will send the sample to a lab for testing.
