Gastroscopy

WHEN AND FOR WHAT KIND OF COMPLAINTS IS AN ENDOSCOPIC EXAMINATION PERFORMED?

If the patient's symptoms include recurrent abdominal pain, vomiting, bleeding, or anemia, our internal medicine physician may prescribe an endoscopic examination to establish the diagnosis. With an endoscope, small changes can be detected in the gastrointestinal tract that would easily remain undiagnosed by other methods.

WHAT HAPPENS DURING THE EXAMINATION?

A gastroscopy is an examination in which an endoscope (a flexible fiber-optic tube) is inserted through the mouth into the upper digestive system. This allows the doctor to examine the mucous membranes of the esophagus, stomach and duodenum (the first part of the small intestine).

During a gastroscopy, if the doctor detects an abnormality or inflamed area, he may take a small tissue sample (biopsy) for histological analysis, culture tests and detection of bacteria.

A gastroscopy is suitable for detecting ulcer disease, inflammation, and the possible source of bleeding. It more accurately recognizes inflammation, ulcers and abnormalities than non-interventional procedures (e.g., x-ray, ultrasound, MRI scans, etc.). It makes possible biopsy, culture tests, removal of polyps and benign growths, a widening of constrictions (stenosis dilation), and a cessation of bleeding (local hemostasis).

A gastroscopy can be performed on an empty stomach. The test is preceded by spraying the throat with a local anesthetic. The tube enters the esophagus, leaving the airways free, so it does not interfere with breathing. The procedure is well tolerated, although it may involve a little discomfort and burping. To avoid this, the test can also be performed under anesthesia. After anesthesia, as reflexes and common sense may be impaired by the medication received, it is not possible to drive for 24 hours. After gastroscopy under anesthesia, a few hours of hospital observation is required. You may experience a sore throat for a few hours, and short-term bloating may occur. After leaving the hospital, you can resume your normal diet.

HOW SHOULD I ARRIVE FOR THE EXAMINATION?

The examination is performed on an empty stomach, so do not eat for 6 hours, or drink for 3 hours beforehand. Milk and dairy products should be avoided if possible that day. Regular medications should be taken as usual on the morning of the procedure.

Medication that affects blood clotting should be discontinued or replaced as directed by a doctor prior to the procedure (based on the advice of your doctor or anesthetist).
