An endoscopy is a minimally invasive procedure used to observe the inside of the patient’s body. An endoscope, a
thin and flexible instrument equipped with a light and camera, is inserted through the mouth or anus, and used to
take live images of the internal organs, which are then displayed on a monitor.
An endoscopy is also conducted to extract samples for imaging and biopsy tests, as well as perform minor surgeries such as polyp removal. It is a relatively safe and painless procedure sometimes performed under sedation.
An endoscopy is useful for both diagnosing and treating a condition while simultaneously avoiding invasive procedures like open surgery. A colorectal surgeon may order an endoscopy for the following reasons:
Endoscopies are typically performed alongside other imaging and blood tests.
As a minimally invasive procedure, an endoscopy normally takes less than an hour to complete. It does not require an
overnight stay at the hospital, and some may be performed without sedation.
For most types of endoscopies, the patient is advised to fast for 12 hours before the procedure. Liquids may be allowed until two hours before the operation, depending on the type of endoscopy.
For patients who are going to have their gastrointestinal tract examined, they will be prescribed laxatives or enemas to help clear the bowels before the endoscopy. Any medications being currently taken, allergies and other conditions should be disclosed to the doctor to allow for certain adjustments in the endoscopy, if necessary.
