Gastroscopy is performed after throat anaesthesia using an anaesthetic spray, therefore it is painless. This test allows for a close examination of the inside of these organs, observing and photographing lesions and collecting samples from lesions in order to examine them under a microscope or in order to perform a urease test, which detects the presence of Helicobacter pylori.
For the test, the patient should arrive on an empty stomach - without eating, drinking or swallowing medication at least 6 hours before the test. The patient also shouldn't smoke on the day of the test. Dentures should be removed before the test. If the patient is taking medicines reducing blood clotting (aspirin, Acard, Polocard, acenocoumarol, Sintrom, warfarin, heparin injections), the physician conducting the test should be notified, because taking samples when on these medications may result in a haemorrhage.
Colonoscopy, which is the test of the entire colon, from the rectum to the caecum (about 150 cm), is the best and fastest growing non-invasive method to detect diseases of this organ, in particular colorectal cancer.
Colonoscopy is usually accompanied by patient discomfort and a feeling of tightness in the abdomen. The patient may have a colonoscopy performed with an intravenous anaesthesia, which is carried out by an anaesthesiologist with a nurse anaesthetist.
The patient prepares for colonoscopy at home. An absolute diet is required. The patient drinks about 2 to 3 litres of clear fluids, usually still water and clear juices, and takes FLEET PHOSPOSODA, mediation which cleans the colon, the use of which does not require the performance of an enema before the test.
