The organ “stomach” must be familiar to everyone, because this organ is related to eating and is a digestive organ of the human body. The stomach is still relatively prone to problems, such as stomach pain, bloating, acid regurgitation, indigestion, acute gastroenteritis, etc. These more common problems in life are related to the stomach. I have an upset stomach, what tests can I do? Today, Dr. Chen will take stock of it.

First, gastroscope

For gastroscope, everyone must be familiar with it, even if there is no gastroscope Tried it myself, or at least should have heard of it. A gastroscope is mainly composed of a tube with an endoscope at the top of the tube. The light guide fiber is wrapped in the hose. The operating doctor can see the inside of the stomach through the display screen.

The gastroscope enters from the mouth and reaches the stomach through the esophagus, and the position of the duodenal bulb is usually checked. Therefore, gastroscopy can examine the three positions of the esophagus, stomach, and duodenal bulb.

Gastric endoscopy is the most commonly used and most accurate examination method for the esophagus, stomach and duodenum. In addition to checking and taking biopsy, gastroscope has the following functions:

1) Under direct vision, gastroscope can examine the esophagus, stomach, 12 Hemostasis is performed at the site of dental bleeding.
2) Remove foreign objects in the stomach, such as fishbone, bones, coins, bottle caps, etc.
3) Small or pedunculated polyps are subjected to endoscopic snare, electrocoagulation, etc.
4) Mucosal resection or stripping is performed for early gastric cancer or larger benign tumors.

Gastric endoscopy can be said to be very good for gastric examination, especially the development of some gastroscopic surgeries, which has made the operation that was supposed to be open to be minimally invasive , so that the damage to the patient will be less.

Second, barium meal for gastrointestinal tract

Barium meal is also a commonly used examination method for gastrointestinal tract. need to take barium sulfate. Barium sulfate is not absorbed by the body and is safe. After taking barium sulfate, barium sulfate will attach to the surface of the stomach wall, and then X-ray imaging, showing the entire outline of the stomach.
Compared with gastroscopy, the advantage of barium meal examination is that it is less painful, but the examination is not as accurate as gastroscope. Barium meal can only see the outline of the digestive tract and is easy to cover up tiny lesions. When there is no diagnosis or suspicion, gastroscopy is still required.
For those who have contraindications to gastroscopy and are unwilling to do gastroscopy, barium meal angiography can be selected.

Three. Abdominal plain radiograph

abdominal radiograph is mainly suitable for Examination of patients with gastroduodenal perforation. After the stomach or duodenum is perforated, the gas inside will run out, and the gas will go up, so it accumulates under the diaphragm. In normal people, there is no free gas under the diaphragm.
Under X-ray irradiation, the gas under the diaphragm appears as a transparent crescent-shaped gas shadow.

Fourth, CT examination

CT examination for ulcers Perforation is also meaningful, even better than a plain abdominal radiograph, and can detect inflammation, mass, and fluid accumulation in the tissue surrounding the perforation.

V. Examination of Helicobacter pylori

Helicobacter pylori infection May cause gastritis, stomach, duodenal ulcer, gastric cancer and other diseases.

Monitoring methods for Helicobacter pylori include invasive and non-invasive tests. Invasive tests include rapid urease test and gastric mucosal tissue staining. Detected during inspection.
Non-invasive tests include C13 or C14 breath tests.

Summary:

Stomach examinations are mainly the above, among which gastroscopy is the most important and most accurate examination. If you are over 40 years old and have abdominal distension, abdominal pain, and peptic ulcer, it is best to have a gastroscope and check for pylorus. Helicobacter infection.
