Gastroendoscopy inspection uses a thin tube with a diameter of about one centimeter, wrapped in black plastic and containing optical fibers, that is inserted through the mouth and into the esophagus, stomach, and duodenum. The tube's front end is equipped with an endoscope that allows physicians to observe the digestive system's health using strong light emitted by a light source and guided through the optical fibers, which can bend the light. If necessary, a forceps can be inserted through a small hole in the gastroscopy tube for a biopsy. The entire inspection process takes about 10 minutes, or 20-30 minutes if a biopsy is performed.
In a typical gastroscopy inspection, the physician holds the tube's front end in their right hand and slowly inserts it into the mouth and to the root of the tongue, which can cause nausea. When nausea is obvious or anytime the patient swallows, the opening at the top of the esophagus will widen, and the physician will insert the gastroscopy tube through the opening. If the patient does not cooperate well, the physician will often advise them to swallow, which can help.
Before the operation, it is the physician's responsibility to obtain a medical history from the patient, and it is also the gastroscopy room nurse's important job to do so. Understanding the patient's medical history enables the operator to take appropriate care of the patient, noting any contraindications or allergies to anesthesia medication, taking blood pressure, pulse, and breathing, and notifying the physician immediately if any abnormalities are detected. If the patient wears dentures, they should be removed before the inspection to prevent choking in case they fall out.
The gastroscopy inspection is an invasive operation, and many patients believe that it is painful and have concerns about the level of safety and disinfection effectiveness of the gastroscopy tube, which can cause fear and a lack of understanding about how to cooperate during the procedure and what to do afterward. Therefore, the physician should explain to the patient the importance and advantages of electronic endoscopy gastro, which can directly observe abnormal changes in the gastrointestinal tract, accurately measure the size and depth of lesions, and obtain tissue samples for pathological examination. Electronic gastroscopy is safe, convenient, and has a higher diagnostic accuracy with clearer images than other examinations. At the same time, the goals of the inspection, how to cooperate during the procedure, and possible complications should be explained, patiently addressing any questions or concerns, and targeted psychological care should be provided to patients of different ages, professions, and cultural backgrounds to ensure a successful examination.
1. Easy Inspection
Using electronic gastroscopy inspection, patients can complete the entire inspection and treatment process while awake. The entire process takes only 2-3 minutes. After inspection and treatment, patients usually only need to rest for about 5-10 minutes before going home. Because gastroscopy inspection and treatment are relatively painless, short, highly accurate, and safe, this technique has been welcomed by many gastrointestinal disease patients.
2. Clear Inspection
When using gastroscopy for gastric examination, the diseased tissue is enlarged, and the physician can clearly view the internal condition of the stomach, leaving no dead corners and causing no damage, with a high diagnostic rate. The inspection and treatment are safe, short, and cause no discomfort to the patient during the procedure, and the patient recovers quickly after examination, with the physician able to give an accurate diagnosis, facilitating the judgment and treatment of the disease.
3. Interventional Treatment
gastroendoscopy is not only used for diagnosing diseases but also has a significant role in the interventional treatment of gastric diseases. Under the direct view of a gastroscopy, polyps can be removed using a high-frequency electric knife, completely avoiding the pain of traditional surgery and preventing the polyp from becoming malignant.
