A colonoscopy generally takes about 15-30 minutes, and may take longer depending on the complexity of the case.
The colonoscopy usually starts with an anorectal examination, which usually lasts 1-2 minutes. This is followed by a colonoscopy, which takes at least 20 minutes to visualize the intestinal tract.
If polyp removal, biopsy, hemostasis and other operations are required, it will take more than 30 minutes. However, in the case of painless colonoscopy, as the examination process involves anesthesia, additional time for anesthesia awakening is required, which is about 5-10 minutes.
Enteroscopy is mainly used to assist in the diagnosis of intestinal disorders. It is suitable for people who have intestinal discomfort and cannot detect lesions using other means. The test should be performed with caution in pregnant women, patients with significant coagulation abnormalities, and patients with severe intestinal obstruction. Fasting is required to perform this test.
If you need to undergo colonoscopy, you should go to the hospital in time and actively cooperate with the doctor’s operation in order to clarify the disease and treat it as soon as possible.
