What is Upper Gastrointestinal Endoscopy?
Upper gastrointestinal endoscopy is a medical procedure performed to examine the upper digestive tract, including the esophagus, stomach, and the first part of the small intestine, called the duodenum. Also known as gastroscopy, this technique allows the doctor to view and evaluate the internal structures of the digestive system through a flexible instrument called an endoscope.
How does it occur?
During the upper gastrointestinal endoscopy procedure, the patient is sedated to ensure comfort and relaxation. The endoscope is inserted through the mouth and passes through the esophagus to reach the stomach and duodenum. The instrument is equipped with a high-resolution camera that transmits real-time images to a monitor, allowing the doctor to carefully examine the digestive mucosa and identify possible abnormalities.
What is it for?
Upper gastrointestinal endoscopy is used for various diagnostic and therapeutic purposes. Some of the main objectives of this procedure include:
- Detection and diagnosis of gastrointestinal diseases, such as ulcers, inflammations, tumors, and lesions.
- Evaluation of symptoms, such as abdominal pain, heartburn, gastroesophageal reflux, difficulty swallowing, and digestive bleeding.
- Performing biopsies for laboratory analysis of suspicious tissues.
- Treatment of some conditions, such as the removal of polyps, dilation of stenoses, or stopping of bleedings.
Upper gastrointestinal endoscopy is a safe and effective procedure, widely used in medical practice to assist in the accurate diagnosis of gastrointestinal diseases and guide appropriate treatment.
Preparation and Recovery
Before endoscopy, the patient is usually instructed to fast for a certain period of time to ensure that the stomach is empty during the procedure. In addition, some medications may need to be temporarily suspended.
After endoscopy, the patient is observed for a short period of time until the effects of sedation decrease. It is normal to feel some discomfort in the throat and have a feeling of fullness in the stomach. However, these symptoms usually disappear quickly.
It is important to follow all medical guidelines after the procedure, including resuming normal eating and the use of prescribed medications, if necessary. In case of unusual or worrying symptoms, it is essential to contact the responsible doctor.
Conclusion
Upper gastrointestinal endoscopy is a valuable procedure for the diagnostic and therapeutic evaluation of diseases of the upper digestive tract. Through this safe and effective method, doctors can examine the esophagus, stomach, and duodenum in detail, identifying abnormalities and assisting in appropriate treatment. Proper preparation and adherence to post-procedure medical instructions are essential to ensure a smooth experience and accurate results.
