The time for gastroenteroscopy is related to the examination program, the patient’s physical condition and disease, etc. It usually takes 20 to 30 minutes.
Gastroscopy is currently the most reliable method to diagnose esophageal, gastric and duodenal diseases. It can directly and clearly observe the lesions in the examined area, and histopathological biopsy of suspected lesions can also be performed through gastroscopy.
An ordinary gastroscopy usually takes about 5-10 minutes, and may take about 30 minutes if there is bleeding from a peptic ulcer, which requires gastroscopy, or gastroscopic treatment for gastrointestinal bleeding.
Colonoscopy is a procedure that utilizes a colonoscope to enter the rectum through the anus and up to the large intestine in order to observe the colon and the interior of the large intestine. It is currently the best option for diagnosing lesions in the mucosa of the large intestine and the interior of the colon, and the entire procedure takes about 15 minutes.
The time required for the examination varies depending on the patient’s physical condition and disease. If the patient is relatively young and does not have any other special lesions, and the entry into the mirror is smooth, the examination time will be relatively short. If lesions are found during the gastroenteroscopy, such as suspicious tumors, polyps, bleeding, etc., and further biopsy or treatment is required, the examination time can be relatively longer.
