Flexible endoscopy uses a specially designed viewing instrument to investigate organs and structures inside the body. Before you undergo an endoscopic examination, you may be given an anaesthetic or sedative. The endoscope is inserted through a natural opening, such as the mouth, or a small incision and is guided to the appropriate area by the specialist. A tiny camera at the tip of the endoscope sends views back to the eyepiece and monitor. Very fine surgical instruments may be passed down the endoscope, allowing minor procedures, such as the removal of tissue samples, to be carried out.
