A friend, who was middle-aged, had recently developed vague pain in the upper abdomen under the glabella, fullness and discomfort after eating, and occasional nausea and vomiting, with no success with medication. He was advised to undergo gastroscopy by his local physician, who issued a gastroscopy request form and made an appointment for the examination in the morning of three days later. When my friend heard that he was going to have a gastroscopy in three days, he was totally confused and scared. When he called his lover, friends and me, he was almost fifty years old, he was incoherent and almost cried, and asked repeatedly on the phone, “Dr. Wang, do I have stomach cancer if I need a gastroscopy?” On the phone, I guided him from a professional point of view, told him to stabilize his emotions, avoid blind anxiety, and carefully prepare for the gastroscopy according to the notes on the appointment form. Later, the examination was successfully completed, and the result was that the superficial gastritis was not serious, and the symptoms were relieved after taking the right medication, and he was happy to work and live normally again. So, if we need to do a gastroscopy ourselves, how can we properly prepare for the examination and complete it successfully? Here I will give you a detailed explanation from a professional point of view, I hope it can effectively help all readers. First of all, the ideological and psychological preparation: With the improvement of people’s living standard and health consciousness, gastroscopy and colonoscopy are increasingly becoming the routine means of examination, and the World Health Organization advocates that annual gastroscopy should be performed above the age of forty-five in order to detect gastrointestinal tumors with increasing incidence at an early stage, so as to improve the healing and survival rate of gastrointestinal tumors and quality of life. The effectiveness of this measure in Europe, the United States and Japan has been proven. The effectiveness of this measure has been fully affirmed in the prevention and control of gastrointestinal tumors in Europe, America and Japan, and has great promotion value. In our country, we are relatively lagging behind in this area, but it has been gradually promoted in big cities such as North, Guangzhou and Shenzhen and has achieved certain success. Therefore, there is no need to be overly anxious and worried because the physician does not suspect that you have stomach cancer before prescribing gastroscopy, but it is a routine examination. There is no need to be overly anxious and worried. Just calm down, relax and prepare carefully for the gastroscopy. Preparation of diet before examination: Gastroscopy is much simpler than colonoscopy, according to the instructions on the gastroscopy appointment form: stop eating for more than 6 hours and stop drinking for more than 2 hours. Third, the preparation of drugs: gastroscopy checklist physician will give you a few drugs: 1, mucus expectorant (streptavidin) is generally taken orally ten minutes before the examination, its role is to remove a large amount of mucus on the mucosa of our stomach, so that the gastroscopy can be seen more clearly. 2, the expectorant (simethicone oil) is also taken orally ten minutes before the examination, its role is to get rid of the bubbles that exist in the stomach, so that the gastroscopy can be seen clearly and improve the examination results. 3, local mucosal anesthetics: 1% dacronin hydrochloride gum paste or 1% lidocaine gum paste (or water), generally in five minutes before the examination containing or pharyngeal spray. Its role is: to play a local mucosal anesthesia, to reduce the discomfort of nausea and vomiting during the examination. 4, intravenous sedation or anesthesia: now the condition of large hospitals in the gastroscopy room equipped with anesthesiologists, can carry out sedation gastroscopy or painless gastroscopy. Sedation gastroscopy: Generally, one each of bupropion and midazolam (or other sedative drugs such as imipramine) is used, which is pushed intravenously before the examination, so that the examinee is in a relaxed and quiet half-sleep state during the examination to reduce pain and complications caused by agitation. Painless gastroenteroscopy (i.e. general anesthesia gastroenteroscopy): generally propofol or isoproterenol (calculated by body weight) is used, which is pushed intravenously before the examination, allowing the patient to be in a deep sleep state during the examination, without any feeling of the examination, and slowly waking up after the examination. At present, more and more people choose to perform sedation or painless gastroenteroscopy. Preparation of the mouth bite plug: After we lie on the examination bed on our left side, the nurse will ask us to bite down on a disposable plastic mouth bite plug of about 3x2x2cm hollow size and fix it to the back of our neck with an elastic braid. The purpose is to prevent us from inadvertently biting the mirror body during the examination and damaging the mirror or having an accident, and discard it after the completion of the pick-up. V. Notes after the examination: After the examination is completed, do not rush to leave the examination room, you should rest in the specially arranged lounge for more than 15 minutes to recover from emotional and physical emergencies, and wait for the physician to deliver the examination report to you, and listen to the physician’s explanation of the condition and any further related matters that must be dealt with. Sedated and general anesthesia gastrointestinal examinee must be fully awake and rest for more than half an hour and be accompanied by an escort to leave, and cannot drive a motor vehicle or ride a bicycle for 24 hours. Sixth, the examination was done after the relevant treatment precautions: some of the examinees were found to have inflammatory polyps or other suspicious lesions during the examination, the physician will carry out the corresponding pathological examination and clamping and cauterization to remove the treatment of polyps, then we must listen carefully to the physician’s nurse’s instructions, do a good job of post-operative fasting, and come to the hospital within a few working days to receive the corresponding pathology report card. Seven, the examination of H. pylori: At present, our chronic gastritis gastric ulcer patients, the rate of infection of H. pylori is relatively high, must strengthen the examination found and formal treatment to prevent inflammation and ulcer malignancy. Now generally take a relatively easy carbon 13 or carbon 14 blowing examination method. In the examination, we must follow the nurse’s request to carefully blow the examination according to the prescribed action, if the result is positive, we must follow the physician’s request to take regular medication to ensure the success of treatment and regular re-examination. As long as we use a calm mind, rigorous attitude, seriously he respected the implementation of medical advice will be safe and successful completion of gastroscopy, to ensure a healthy and good life to lay a good health care medical foundation.
