Gastroscopy, which has a history of nearly 150 years, was first invented by a German doctor who was inspired by a street sword swallowing performance. Today, it has long become a reliable method for diagnosing esophagus, stomach, and duodenal lesions, and is known as the "gold standard" for gastric cancer diagnosis.
Although traditional gastroscopy has a wide range of important clinical uses, but because it stimulates the root of the tongue during the examination, it can cause nausea, vomiting, coughing and other discomforts, so that many patients are afraid of gastroscopy. "Fearful, even refused to check.
So, what exactly is gastroscopy? What factors determine how we feel when doing gastroscopy? What progress has been made in the development of gastroscopy technology today? Today we will talk about the gastroscopy.
The most effective way to check stomach problems
Inclusive of all rivers. Our stomach is like the ocean of the human body. It receives various foods and medicines every day. Of course, it is also filled with various liquids, such as water, tea, wine, and beverages. Almost everyone can tell a few short stories about their "stomach problems"!
Just imagine, the food, medicines and liquids we eat and drink may damage our stomachs because they are too hot or too cold, or it may be that bacteria or viruses come in with food and damage our stomachs. Many drugs, such as aspirin that many people often take, can also directly damage the gastric mucosa, leading to erosions and ulcers. Due to genetic susceptibility factors, Helicobacter pylori infection, bad habits of tobacco and alcohol, long-term consumption of preserved food or food contaminated with mycotoxins may also promote the occurrence of gastric cancer.
Once you have these stomach problems, what methods should be used to check them?
Among all the examination methods related to esophagus, stomach and duodenal diseases, gastroscopy is the first method deservedly.
The gastroscope includes a tube with an electronic image sensing device at the front end, which is responsible for collecting images of the gastroesophageal mucosa, and an operating handle. The doctor can adjust the direction of the front end of the mirror to inflate the stomach and rinse with water. You can also take tissue through a biopsy hole for pathological examination, and even perform minimally invasive surgery to cut off early gastric cancer, excavate stromal tumors, and remove the gallbladder through a gastroscope. If you accidentally swallow a foreign body, you can go through a thin tube to grab the pliers or net bag to catch the foreign body. The other end of the gastroscope is connected to the main body of the gastroscope through the light guide part to provide the gastroscope with a light source, aspiration, and image processing such as electronic staining to help determine whether there is early cancer.
Of course, doctors and nurses can see all these operations clearly on the monitor screen. How clear is the gastroscope? It was as clear as our doctor "drilled" into the patient's stomach, as if looking face to face to see how many hairs on the other's face, whether it was double eyelids, and whether there were moles.
No pain or injury
Since the gastroscope can stimulate the pharyngeal reflex and cause nausea and vomiting, some patients describe the feeling of doing a gastroscope as follows:
"I did this gastroscope, and I don't want to do it again in my next life!"
"Saliva and tears spewed out unconsciously, retching, uncontrollable, 10 minutes is as difficult as 10 years."
However, some patients who have completed gastroscopy said: "It's not that terrible, and the pain is completely within the uncomfortable range."
Why is there such a huge contrast in the end? This is like "like a fish knowing that it is warm and cold when drinking water", and everyone's experience of doing gastroscopy is also different. There are three main factors that determine how we feel when doing gastroscopy.
One is the degree of sensitivity and tolerance. Some people have extremely sensitive pharynx, not to mention the gastroscope, even the lower gastric tube can not tolerate this. This is a congenital factor, and the doctor's encouragement and comfort will not help. Other patients are too nervous, the more nervous the throat becomes, the more intense the friction of the gastroscope, the more severe nausea and vomiting are caused. The third factor is related to the doctor's level of operation. When encountering a skilled and gentle doctor who can effectively relieve the patient's nervousness, the patient's pain will be less.
Generally speaking, gastroscopy is not dangerous. As long as the patient has no obvious diseases of the heart, lungs and brain, it is still very safe to do gastroscopy.
Before the gastroscope, the patient needs to take oral pharyngeal anesthetics and lubricating glue. When the doctor inserts the gastroscope and passes through the oropharynx, the patient needs to relax and swallow according to the doctor's requirements. As soon as the entrance of the patient's esophagus opens, the doctor can gently insert the gastroscope into the esophagus. After this, the patient inhales deeply through the nose, then exhales it through the mouth, and blows it out when there is saliva in the mouth, and the gastroscopy can be successfully undergone.
Such a conscious examination can make people feel abdominal distension, nausea, and vomiting in severe cases. However, there will be no pain and no damage.
Painless gastroscopy is gaining popularity
With the advancement of technology, the application of anesthesia has become wider and wider, and painless gastroscopy has also emerged.
If you choose to do painless gastroscopy, you must first be evaluated by an anesthesiologist to exclude contraindications to anesthesia. During the formal examination, before the gastroenterologist performs gastroscopy or treatment on the patient, the anesthesiologist will give the patient a propofol-based drug to sleep the patient, and then the gastroenterologist will perform gastroscopy and treatment. After the examination or treatment is over, the anesthesiologist stops the administration, and the patient will soon wake up.
The entire examination takes 10 to 20 minutes. The patient feels that he has a good night's sleep, and he has finished the examination without knowing it.
In recent years, this new inspection method has been recognized by more and more patients. Especially in large hospitals, painless gastroscopy technology has changed more than half of the patients' inherent impression of gastroscopy.
In the Endoscopy Center of Henan Provincial People's Hospital, patients who choose painless gastroscopy account for the vast majority. Only a few special groups still choose traditional gastroscopy, such as those who are allergic to anesthetics or have severe heart disease. For these patients, doctors will try to choose a finer mirror, such as a rhino-gastroscope, to alleviate the pain. At the same time, it is necessary to fully communicate with patients and family members before the examination, explain and comfort them, and reduce the anxiety and anxiety of the patients, so as to achieve good cooperation between doctors and patients during the examination.
In short, there is no damage to gastroscopy, the most is abdominal distension and nausea and vomiting. If you choose a pain-free gastroscope, you will feel nothing at all. So, don’t be afraid of gastroscopy!
