COLONOSCOPY

Colonoscopy is an endoscopic examination of the large intestine (and the end of the small intestine, the ileum).

A colonoscope is a thin, flexible, long tube (endoscope) with a small light source and camera that is gently inserted through the anus into the large intestine and views the lumen of the large intestine from the inside. This allows even minor organic changes to be diagnosed: from superficial inflammation to widespread tumors.

A colonoscope is flexible enough to cope with the curves of the large intestine.

Why is a colonoscopy prescribed?

A colonoscopy is prescribed for both diagnostic and therapeutic purposes.

The most common indications for colonoscopy are:

Abdominal pain, diarrhea, severe chronic flatulence, rectal bleeding, prevention of colon cancer (especially in people with a hereditary predisposition), differential diagnosis of functional lesions of the gastrointestinal tract, etc.
Detection and removal of polyps that have grown from the mucous membrane of the colon,

Colonoscopy is indicated for people aged 45 and older regardless of the presence of complaints.

Colonoscopy with intravenous sedation (sleep, anesthesia).

In some cases, our staff may need to carry out additional cleaning procedures. Therefore, it is necessary to arrive at the center 30 minutes before the scheduled examination time.
One day before (or on the day of) the examination, you will be given a health questionnaire. It must be filled out and sent by e-mail. by mail or brought on the day of the examination so that the anesthesiologist can familiarize himself with your health history and current problems.
3 hours before the anesthesia, you must not eat or drink anything. In the morning, you can only take regular medications, antihypertensive drugs, etc.
Plan your time so that after a colonoscopy under anesthesia, you are under the supervision of an anesthesiologist at the medical center for about 30 minutes.

It is not recommended to drive a car for 3 hours after anesthesia.
