Hello, Duomu Health will give you the answer: That’s right, gastroscopy
Everyone has heard of gastroscopy. In the impression, it is only performed by people with severe gastric discomfort or during physical examinations. Go get it checked out, it's a daunting, scary, and painful test. However, for patients with the upper gastrointestinal tract, it is a very necessary examination to identify the lesions, take biopsies to detect benign and malignant lesions, and directly remove the lesions under the microscope, etc. Especially for the screening of early cancers of the upper gastrointestinal tract, gastroscopy is a magical tool in the hands of doctors! In fact, having enough understanding of the methods, functions and benefits of gastroscopy can eliminate a lot of psychological anxiety and pain.
With the advancement of science and technology and the improvement of medical standards, this examination has been greatly improved. Below, Duomu Health (a one-stop overseas high-end medical consulting service organization) will take you to learn more about the detailed information.
What is a gastroscopy? How to check?
Gastroscope, with the help of a thin, flexible tube inserted into the stomach, allows the doctor to directly observe the internal conditions of the esophagus, stomach and duodenum, especially for the most intuitive judgment of small and early lesions. .
The front end of the gastroscopy tube is equipped with an endoscope. The strong light is emitted by the light source and turned through the optical fiber, allowing the doctor to clearly observe the conditions of various parts of the upper gastrointestinal tract from the display screen at the other end. If necessary, a clip can be inserted through the small hole in the gastroscope to take a cell biopsy (biopsy).
Japanese doctors were the first to invent improved gastroscopy technology and equipment
In 1868, the German doctor Kussmore was inspired by the sword-swallowing swordsman and invented the Kussmore tube, which is actually A long, thin metal tube with a mirror at the end. However, this method caused great pain to patients and was soon abandoned.
In 1950, Tatsuro Uji (1919--1980), a Japanese doctor who had been committed to the early detection and treatment of cancer, overcame manufacturing costs and technical difficulties and successfully invented and improved the prototype of the modern flexible gastroscope— —Intragastric cameras have brought unprecedented changes to the world’s medical community.
The preferred examination method for upper gastrointestinal diseases
Compared with other external examination methods, gastroscopy is the most direct and effective method for examination of various diseases of the upper gastrointestinal tract. From gastritis, antral gastritis, gastric ulcer, chronic gastric diseases caused by Helicobacter pylori, to duodenal cancer, gastric cancer, and esophageal cancer, gastroscopy allows doctors to accurately judge with the naked eye or cell sampling and biopsy. .
Especially for middle-aged and elderly people who often suffer from stomach discomfort and are over 40-50 years old, regular gastroscopy during annual physical examination is the most direct and effective way to prevent major diseases of the upper gastrointestinal tract.
Nasal entry gastroscope
The commonly used gastroscope equipment in China is the oral entry type. The diameter of the gastroscope tube is relatively thick, and it is easy to cause vomiting when it passes through the sensitive part of the throat, which makes many patients feel vomiting. People are afraid of gastroscopy. Many examiners will choose the painless method of general anesthesia, but anesthetics can damage the human nervous system after all.
In fact, during the examination, as long as you relax, breathe correctly and rhythmically, you can effectively relieve the discomfort. Having enough understanding of the methods, functions and benefits of gastroscopy can eliminate a lot of psychological problems. anxiety and pain.
Japan is the first country in the world to invent and use medical endoscopy technology. Currently, gastroscopes for physical examinations in Japan have adopted nasal cavity entry equipment. The endoscope tube is thin, slightly thinner than the little finger.
Do not eat within 8 hours before gastroscopy. During the examination, you first drink a cup of potion to eliminate gastric bubbles, then instill some medicine to help ventilation into the nasal cavity, and choose the side with smoother side to instill the anesthetic solution. The anesthetic solution will flow into the mouth along the nostrils and needs to be swallowed. Go down and reduce the allergic reaction in the throat, and you will not feel uncomfortable when inserting the endoscope tube later.
The doctor will put the endoscope tube into the nasal cavity, and then go deep into the esophagus and stomach. He will first put the endoscope into the deepest part of the duodenum, and then slowly go from deep to shallow. Slow check.
Generally speaking, the inside of the digestive tract should be smooth. If a foreign object is encountered, water will be sprayed from the micro-nozzle on the endoscope to determine whether it is something growing in the digestive tract, such as a polyp, or an adhesive Undigested food on the lining. When the vision is unclear, iodine will be sprayed for staining. If any problem is found, the doctor will use a micro-device on the head to take a sample and then conduct laboratory tests.
The whole process takes about 20-30 minutes, and the endoscope will take a large number of photos for further observation and confirmation.
