Our clinic performs esophagogastroduodenoscopy (gastric camera) that directly observes the esophagus, stomach, duodenum, etc., and lower gastrointestinal endoscopy (colonoscopy) that directly monitors the inside of the large intestine.
These two endoscopies diagnose the presence of neoplastic lesions such as inflammation and early cancer in the gastrointestinal tract. Both tests allow observation and tissue sampling (biopsy: picking out a tiny piece of tissue and examining it in detail with a microscope, etc.) and a simple endoscope if necessary. You can also perform a surgical procedure.
In rare cases of upper gastrointestinal endoscopy, gastrointestinal bleeding and perforation may occur in this case, hospitalization or urgent treatment/surgery may be required. It has been reported that 0.005% of oral upper gastrointestinal endoscopy and 0.024% of nasal upper gastrointestinal endoscopy for observation in 2008-2012.
It is a method of removing polyps and cancer using an endoscope. This is a method of eliminating early cancer, mainly in the esophagus and stomach, using an endoscope. Methods are divided into polypectomy, endoscopic mucosal resection (EMR), and endoscopic submucosal dissection (ESD), and early cancer, which previously required surgery, can now be resected by endoscopic treatment, which is less burdensome to the body. However, please consult with your doctor as the indication will be determined strictly according to the size and depth of the lesion and the type of cancer. After excision, an artificial ulcer develops in the lesion. In rare cases, bleeding or perforation may occur, so in principle, you should be hospitalized.
The medicines used for gastroscopy leaves different side effects on the patients the side effects of these drugs are as follows:
Leaves no special side effects on the patient
History of local anesthetic hypersensitivity (those who have trouble with dental anesthesia, etc.)
Heart disease, glaucoma, benign prostatic hyperplasia
Glaucoma, respiratory depression
it is used for Respiratory depression
Anesthesia is effective in the throat for about 1 hour after the test. After about an hour, drink a small amount of water and ensure that you don’t get sick before eating. Drink and eat according to the instructions at each facility (usually from 1 hour after the end of the examination and from 30 minutes to 1 hour after the nasal endoscopy).
If you use antispasmodics or sedatives, please avoid driving the car after the inspection on the day of the inspection, depending on the type. The effects of the injections used before the test will remain for some time. Please rest in the clinic for about an hour before returning. Those given intravenous sedatives should not drive for one day (24 hours).
In rare cases, bleeding may occur from the area where the tissue is pinched. Do not exercise vigorously on the day of the test and rest. Drinking alcohol or bathing in hot water can cause bleeding. Please do not drink on the day and stay in the shower. Eat digestible foods.
If you have tissue or polyps, please refrain from strenuous exercise on the day. Also, avoid long baths and take a shower. In addition, there is a stimulus meal, drinking, coffee, etc. Please avoid as much as possible 2-3 days.
In rare cases of upper gastrointestinal endoscopy, gastrointestinal bleeding and perforation may occur and you may require hospitalization or urgent treatment/surgery. The incident rate of upper gastrointestinal endoscopy is reported to be 0.171%
