Gastroscopy
About the procedure
A test that observes the esophagus, stomach, and duodenum, and if necessary, checks for abnormalities through biopsy or endoscopy.
Method
- Get the patient to take a bubble remover in the stomach before the test to clear the gastrointestinal tract.
- By taking or injecting gastric secretion and motility inhibitors, gastric motility and gastric mucus secretion are suppressed to facilitate examination and observation.
- An anesthetic (lidocaine spray) is sprayed into the throat to anesthetize the throat.
- For sedation (sleep) endoscopy, intravenous injection is given, and blood pressure, pulse, and oxygen saturation are measured.
- Before the examination, lie on your side on the examination table with the left side of the body facing down and bite the mouthpiece.
- After inserting the endoscope through the mouth, the esophagus, stomach, and duodenum are observed. During the examination, a biopsy may be performed for an accurate diagnosis.
Colonoscopy
About the procedure
A test method to diagnose inflammation, polyps, and tumors occurring in the colon by inserting an endoscope through the anus and observing the colon.
In addition to the purpose of diagnosis, colonoscopy can directly biopsy the abnormal area. It can also be performed for therapeutic purposes, as polyps can be removed immediately, and hemostasis is possible in case of bleeding.
Method
- Lay down on the bed with the guidance of the staff.
- Lie on your left side with your knees bent and your hips slightly pushed back. At that time, relax your body and breathe comfortably.
- Insert the endoscope through the anus up to the cecum while inflating the intestine with air.
- It takes about 15-30 minutes but may be delayed if a biopsy is performed for an accurate diagnosis.
