The difference between gastroscopy and gastroscopy

As imaging methods, gastroscopy and gastroscopy can both diagnose many gastric diseases. Many people do not quite understand the difference between gastroscopy and gastroscopy. Gastroscopy is mainly a method of examination in which the patient takes a contrast agent, which allows the doctor to diagnose whether there are any lesions in the digestive tract under X-ray irradiation. Gastroscopy is a method of examination that uses a long tube to insert into the human stomach to detect stomach diseases.

1. Different detection methods

1. Gastrointestinal barium meal radiography, also known as digestive tract barium radiography, refers to an examination method that uses barium sulfate as a contrast agent to show whether there are any lesions in the digestive tract under X-ray irradiation. It is often used in patients who cannot tolerate gastroscopy.

2. Gastroscopy is a procedure that uses a thin, soft tube to be inserted into the stomach, allowing the doctor to directly observe lesions in the esophagus, stomach, and duodenum, especially tiny lesions. But the patient will feel uncomfortable.

2. Which test result is more intuitive and accurate?

The contrast examination of the stomach is also called barium meal fluoroscopy. It is a type of imaging examination that achieves the purpose of visualization by taking contrast agents. Contrast examination can only indirectly reflect the condition of the stomach and esophagus. It is not as intuitive as gastroscopy, and not as accurate as gastroscopy, so gastroscopy is generally recommended. Gastroscopy mainly involves directly inserting a gastroscope into the stomach and displaying the information on a monitor. If any abnormality is found, a biopsy can be directly taken with forceps, which has high accuracy. In addition, gastroscopy can also be used as a minimally invasive surgery to treat mild lesions of the gastroesophageal tract. It can directly examine the condition of the esophagus and gastric mucosa and is the most intuitive examination method.

3. Advantages and disadvantages of both

1. Advantages and disadvantages of gastroscopy

Gastroscopy is more intuitive than upper gastrointestinal tract radiography and can take biopsies of lesions. However, for those who cannot pass the gastroscope due to esophageal and gastric lesions, upper gastrointestinal tract radiography can be chosen. The disadvantage of gastroscopy is that it is an invasive examination and is rather uncomfortable. However, gastroscopy is currently the most reliable method for diagnosing esophageal, gastric and duodenal diseases. No other examination methods, including upper gastrointestinal barium angiography, electrogastrogram and gastrointestinal color B-ultrasound, can replace it.

2. Advantages and disadvantages of gastroscopy

Compared with fiber gastroscopy, upper gastrointestinal tract radiography plays a greater role in the diagnosis of larger typical esophageal cancer. Gastrointestinal tract radiography can display its inner cavity and mucosal folds, morphology and function, etc. It has important diagnostic value for common gastrointestinal diseases such as ulcers and cancers. However, for early and smaller esophageal cancers, its diagnosis rate is not ideal, only about 75%, and the X-rays of upper gastrointestinal tract angiography contain radiation.
