The length limitation of colonoscopy makes it impossible for the colonoscope to reach the small intestine, therefore colonoscopy is not performed to examine the small intestine.
The commonly used colonoscopy in clinical practice refers to colonoscopy, and the general length of colonoscopy is about 1.3 meters, while the average length of adult colon is 1.5 meters, so the small intestine is far away from the anus, and the approximate length of the small intestine is 5~7 meters, so colonoscopy does not reach the small intestine, and it is not possible to carry out a comprehensive test of the small intestine.
The reason why colonoscopy is performed is to exclude or eliminate the possibility of cancer and inflammation in the gastrointestinal tract, and the small intestine, which is a human tissue, also has the possibility of abnormal proliferation, cancer, and inflammation. Therefore, examination of the small intestine is also in demand by some patients.
If you want to have your small intestine examined, there is a small colonoscopy that is designed to examine the small intestine, and you can also choose capsule endoscopy or gastrointestinal imaging to have your small intestine examined. If you are ready to carry out small bowel examination, please go to a specialized hospital and under the guidance of a doctor.
