Comparing Upper Endoscopy and Upper Gastrointestinal Series: Choosing the Right Test for You if Endoscopic Examinations Seem Daunting.

South Korea is known to have the highest incidence of stomach cancer in the world. This is closely associated with the dietary habits of Koreans, who enjoy spicy and salty foods. Particularly, the habit of consuming broth-based dishes with various side dishes leads to inflammation of the gastric mucosa, increasing the infection rate of Helicobacter pylori, one of the main causes of stomach cancer. For this reason, the importance of screening to detect stomach cancer early cannot be overstated. Upper endoscopy and upper gastrointestinal series are representative methods of screening for early detection of stomach cancer. These two screening methods are crucial tests that adults aged 40 and over should undergo every two years. Now let's explore the differences between these two screening methods and their respective advantages and disadvantages.

 

Early detection of stomach cancer is crucial. Regular screening to detect stomach cancer early and receive appropriate treatment is the best way to maintain health.

 

Upper Endoscopy Examination

Upper endoscopy examination involves inserting an endoscope through the mouth to directly observe the esophagus, stomach, and duodenum. This examination can be divided into sedated and unsedated methods, and it allows for tissue sampling and polyp removal during the procedure. Sedated endoscopy administers sedatives to ensure that patients do not experience discomfort during the examination, while unsedated endoscopy is performed without sedation.

 

The main advantages of upper endoscopy examination are as follows.

• Precision diagnosis: Direct visual confirmation through the endoscope allows for accurate diagnosis, even of small lesions.
• Tissue sampling and polyp removal: Abnormal tissues discovered during the examination can be immediately collected for pathological examination, and polyps can be removed promptly.
• Quick result confirmation: Results can be confirmed immediately after the examination, allowing for swift diagnosis.

However, there are also some drawbacks to upper endoscopy examination.

• Discomfort: Side effects such as throat pain, foreign body sensation, and post-examination bleeding may occur.
• Sedative side effects: Sedated endoscopy requires a recovery period after the examination due to sedative use, and some patients may experience side effects from sedatives.

 

Upper Gastrointestinal Series Examination

An upper gastrointestinal series involves taking a contrast agent and undergoing X-ray imaging to observe the stomach. The contrast agent coats the stomach wall, allowing the shape of the stomach and the presence of abnormalities to be confirmed during X-ray imaging.

 

The main advantages of an upper gastrointestinal series examination are as follows.

• Less discomfort: Since an endoscope is not inserted, there is less physical discomfort.
• Relatively simple procedure: The examination procedure is relatively simple and can be completed within a short period.

However, there are also some disadvantages to an upper gastrointestinal series.

• Limitations in accuracy: The accuracy of detecting lesions may be lower compared to upper endoscopy, and additional endoscopic examinations may be required if abnormalities are found.
• Contrast agent side effects: Constipation may occur due to the contrast agent, requiring adequate fluid intake after the examination.

 

Preparation for Examination

Proper preparation is necessary for accurate results for both examinations. Fasting for over 8 hours before the examination is essential, and water, gum, smoking, and alcohol should all be avoided. Additionally, consultation with medical professionals regarding medication use, surgical history, and denture wearing is necessary beforehand.

 

Criteria for Selection and Conclusion

The choice between upper endoscopy and upper gastrointestinal series depends on various factors. Upper endoscopy offers precise diagnosis and immediate treatment advantages, while upper gastrointestinal series provides less discomfort and simplicity during the examination. Considering one's health status, comfort with the examination, and recommendations from medical professionals is crucial when making a choice.
