Electronic gastroscope

The electronic gastroscope can obtain high-definition images, and various image processing can be performed by a computer to perform three-dimensional imaging, measurement of mucosal blood flow, mucosal local hemoglobin content, and local temperature. In addition to the three main parts of the endoscope, the TV information system center and the TV monitor, the electronic endoscope is equipped with auxiliary devices such as a video recorder, a camera, an aspirator, a keyboard for inputting various information, and a diagnostic treatment. Various treatment instruments, etc. Basic Information Specialist classification: Digestive examination classification: endoscope Applicable gender: whether men and women apply fasting: fasting Tips: Change to a digestible diet 1 day before the test, fasting and forbidden water for 8 hours before the test. Normal value No abnormalities. Clinical significance Abnormal results: (1) Esophagitis: Esophagitis is generally classified into mild, moderate, and severe types under endoscopy. (2) esophageal ulcer: erosion refers to epithelial tissue defects in the esophageal mucosa. If the lesion reaches the submucosa and the muscularis propria, it is called ulcer. (3) Esophageal varices: Esophageal varices are blue or cyan under endoscopy, and the shape is serpentine or hemispherical, distributed along the long axis of the esophagus. (4) Esophageal cancer. (5) Gastric ulcer: The basic form of gastric ulcer is characterized by mucosal defects, white moss on the bottom of the ulcer, inflammatory reaction such as edema and congestion at the edge, and mucosal wrinkles concentrated to the ulcer. (6) Gastric cancer: It can detect early gastric cancer on the one hand, and can identify benign and malignant ulcers at the same time. It can also determine the type of gastric cancer and can track precancerous lesions. (7) duodenitis: visible endoscopic mucosal congestion, edema, rough, spotted hemorrhage, stasis or ecchymosis, spotted or patchy erosion, visible blood vessels in the mucosa or thick wrinkles and Nodule. Need to check the crowd: various lesions in the stomach and some patients with esophageal diseases. Precautions Before the examination, the taboo should be changed to a digestible diet one day before the examination. The food is forbidden for 8 hours before the examination. Those who have confirmed the stomach retention will change to the liquid two days before the examination, and the stomach will be sterilized in the evening. The contents of the stomach make the field of vision clear during microscopy. Taboo when checking: 1. Explain that the effect of atropine injection 30 minutes before surgery is to reduce digestive tract secretions. 2. Remove the dentures before the inspection of the dentures. 3. Go to the examination room on time according to the appointment time, and empty the urine before surgery. 4. The patient should not do excessive swallowing during operation to prevent saliva from inhaling the airway and causing pain in the throat. 5. Explain to the patient the purpose of the gastroscopy, encourage the patient to establish confidence, not to be nervous, and cooperate with the doctor to successfully complete the examination. Inspection process An elongated tube enclosing a light guiding fiber with a black plastic having a diameter of about one centimeter. The front end is equipped with an endoscope extending from the mouth into the esophagus of the subject → stomach → duodenum, which is strong by the light source. Light, through the light guiding fiber, can make the light turn, so that the doctor can clearly observe the health of various parts of the upper digestive tract from the other end. Not suitable for the crowd Unsuitable for the crowd: severe heart and lung disease (arrhythmia, heart failure, myocardial infarction, respiratory insufficiency, asthma attacks). Shock, coma and other critical conditions. Unconsciousness and mental disorder. Acute perforation of the upper digestive tract. Severe throat disease, corrosive esophagitis, gastritis, aortic aneurysm, severe neck and chest deformity. Sustained examination of acute infectious hepatitis or gastrointestinal infectious diseases. Adverse reactions and risks Some patients have uncomfortable, such as flatulence, nausea and so on.
