Colonoscopy exam


Gastroclinic is pioneer in Portugal in the use of UltraHD, multiLED equipment that allows advanced image quality for the most accurate and early diagnosis.

For greater patient comfort at Gastroclinic, all exams can be performed under anesthesia.

This exam will allow the Doctor to look at your large intestine and, if necessary, the final portion of your small intestine. 

This test plays a very important role in the diagnosis of cancer precursor lesions (polyps) and their treatment (endoscopic polypectomy).


This exam is indicated from the age of 50, or earlier if there is a family history of colorectal cancer. Whenever an injury is detected, techniques that allow for a better characterization can be performed:

Before the Exam

For the observation to be conclusive and thorough, your intestines must be clean. For this purpose you will have to ingest a liquid with a laxative effect. In the pre-exam assessment we will recommend the preparation that best suits your case.

Before the exam, an evaluation of your medical history, tests and other tests will be scheduled na Gastroclinic.


This visit is important so that we can clarify doubts regarding the preparation for bowel cleansing and the exam itself. You will be given written information about exam preparation and informed consent.​

on exam day

On the day of the exam you will be met by a nurse na Gastroclinic who will explain the procedures. You will be given appropriate clothing for the procedure and then prepared for the examination.

Before the exam starts the Doctor will talk to you and then you will be monitored so that intravenous anesthesia can be administered by an Anesthetist and start the exam.

On average a diagnostic examination will take 20-25 minutes and a little longer if endoscopic therapy is required.

After Exams

You will be observed for 30-60 minutes and then you will be served a light meal. Then, the gastroenterologist will explain the results of the exam and schedule an appointment if necessary.

Since you have been given an anesthetic medicine for the test, you should not drive or operate other machines or drink alcohol on the day of the test.

After discharge, you will be able to eat and drink and resume your usual medication (unless medically indicated otherwise). The next day you can resume your normal activity.
