Gastroscopy
What is a gastroscopy?
Gastroscopy is a medical examination in which the doctor uses a gastroscope—a thin, flexible tube with a camera at the end—to examine the inside of the upper digestive tract. This examination allows detailed visualization of the esophagus, stomach, and duodenum (the first part of the small intestine). Gastroscopy is one of the endoscopic methods and is considered a highly effective tool for diagnosing and treating various gastrointestinal issues.
How is a gastroscopy performed?
Gastroscopy is typically an outpatient procedure that lasts approximately 10–15 minutes. The patient lies on their left side, and a plastic mouthpiece is inserted into the mouth to prevent accidental biting of the device. To reduce discomfort, a local anesthetic in the form of a spray is often applied to the throat. In some cases, the procedure can be performed under short-term sedation.
The doctor carefully inserts the gastroscope through the mouth, down the esophagus, into the stomach, and the duodenum. The camera at the end of the device transmits images to a monitor, allowing for a detailed examination of the mucosa and identification of potential pathological changes such as inflammation, ulcers, or tumors. During the procedure, a tissue sample (biopsy) may be taken for further histological examination.
Why is a gastroscopy performed?
Gastroscopy has both diagnostic and therapeutic significance. It is typically indicated for the following conditions or concerns
- Chronic digestive issues: such as heartburn, abdominal pain, nausea, or vomiting.
- Upper gastrointestinal bleeding: which may manifest as vomiting blood or the presence of black stool.
- Suspected peptic ulcers: in the stomach or duodenum.
- Examination of suspicious findings: such as polyps or tumors.
- Celiac disease: to verify damage to the small intestine mucosa.
Gastroscopy can also be used therapeutically, for example, to remove foreign bodies, stop bleeding, or remove polyps.
How to prepare for a gastroscopy?
Before the procedure, it is necessary for the patient to be fasting—usually at least 6 hours without food and 2 hours without liquids. If the patient is taking medications, it is advisable to consult the doctor to ensure the medications do not affect the results or the procedure.
Is gastroscopy painful?
The examination itself is more uncomfortable than painful. Patients may feel pressure in the throat or mild gagging as the device passes through the esophagus. Local anesthesia or sedation significantly reduces discomfort, and most patients tolerate the procedure well.
The importance and safety of gastroscopy
Gastroscopy is considered a safe procedure with minimal risk of complications. In the hands of an experienced specialist, it allows for a quick and accurate diagnosis and targeted treatment. Although the procedure may be associated with some discomfort, its benefits for the early diagnosis of serious diseases, such as stomach cancer or esophageal varices, greatly outweigh any temporary discomfort.
Inhalation of Entonox
Entonox is used during gastroscopy as a form of analgesia. It is a safe and fast-acting method to alleviate discomfort during the procedure. The analgesic effect reduces pain perception, making the procedure more comfortable. The anxiolytic effect helps calm the patient and allows them to better manage the discomfort associated with the insertion of the endoscope. Entonox is safe, easy to use, and a suitable alternative to pharmacological sedation.
