What is the clinical significance of gastroscopy

Significance: Lesion tissue can be taken for pathological cell examination under gastroscopy to clarify the nature of the lesion, which is the "gold standard" for diagnosing various chronic gastritis, gastric ulcer, esophageal cancer and gastric cancer. Gastroscopy can also carry out a variety of **:

high-frequency electrocution of gastric polyps; Gastroscopic spraying to stop bleeding, injection to stop bleeding, titanium clip to stop bleeding**; Microscopic gastric cancer resection; Microscopic microwaves** and so on.

The development of gastroscopy has shown superior clinical effects, and some of the original surgeries that require laparotomy can now be completed under gastroscopy, eliminating the pain of laparotomy for patients, with good efficacy and low cost. Gastroscopy is currently one of the most intuitive, accurate and reliable methods for diagnosing esophageal, gastric and duodenal lesions, and the use of electronic gastroscopy has greatly improved the diagnostic level of gastric diseases.

According to the current level of medical care, if patients have symptoms such as nausea and vomiting, nausea and heartburn, stomach pain and bloating, doctors will generally recommend that they do a gastroscopy first, which can facilitate doctors to know the condition more accurately; On the other hand, the severity of gastrointestinal diseases can be judged, so as to find out the best and prescribe the right medicine.

The main examination of gastric disease is gastroscopy, which can not only directly observe the surface of the gastric mucosa, but also do pathological biopsy of the gastric mucosa at the same time to confirm the correctness of the disease seen. To judge the degree of chronic gastritis and the presence or absence of intestinal metaplasia, and to distinguish the benign and malignant ulcer lesions, the clinical significance is as follows: Clinical significance of gastroscopy:

1. Esophagitis is generally divided into three categories under endoscopy: mild, moderate and severe. 2. Esophageal ulcer erosion refers to a defect of epithelial tissue in the esophageal mucosa. If the lesion reaches the submucosa and muscularis propria, it is called an ulcer.

3. Esophageal cancer Esophageal cancer is the most common esophageal disease. Approximately endoscopic diagnosis of esophageal disease, esophageal varices are more common due to portal hypertension caused by cirrhosis. Less commonly, tumors compress the superior vena cava.

Esophageal varices are endoscopically blue or cyan in shape serpentine or hemispherical and distributed along the long axis of the esophagus. 5. Gastric cancer Gastroscopy is of great significance to the diagnosis of gastric cancer. On the one hand, it can detect early gastric cancer, and at the same time, it can distinguish between benign and malignant ulcers.

It can also determine the type of stomach cancer and track precancerous lesions. 6. Gastric ulcer Gastric ulcer and its different periods in the healing process have considerable variation in their manifestations under gastroscopy. The basic form of gastric ulcer is characterized by mucosal defects, the bottom of the ulcer is covered with white lichen, the edges are inflammatory reactions such as edema and hyperemia, and mucosal folds that concentrate towards the ulcer may appear.

7. Duodenitis mucosal hyperemia, edema, rough unevenness, punctate hemorrhage, petechiae or ecchymosis, punctate or patchy erosion, mucosal vascular exposure or coarse folds and nodules can be seen during endoscopy. 8. Duodenal ulcer Gastroscopy has great value in the diagnosis and efficacy of duodenal ulcer.

Gastroscopy is mainly used for direct examination and **: esophagus, stomach, duodenum and various diseases, and can stop bleeding, remove small tumors and do biopsy.

Hello, whether it is for the diagnosis of upper gastrointestinal diseases or health check-ups, gastroscopy is very important. Gastroscopy is currently the most thorough examination method for gastric diseases, although in recent years, there have been B-ultrasound, MRI and other examination methods, but they are not as clear as gastroscopy, which is conducive to accurate diagnosis.
