If you don’t want to do colonoscopy, there is no test that can completely replace colonoscopy. If you can’t realize colonoscopy due to special reasons, you can use capsule endoscopy and traditional gastrointestinal imaging to do the test. 1. Capsule endoscopy: the full name is “intelligent capsule gastrointestinal endoscopy system”, its size looks like a drug capsule, built-in camera and signal transmission device. Through the capsule endoscopy can understand the patient’s entire digestive tract, can make a diagnosis of intestinal diseases. However, capsule endoscopy can not completely replace colonoscopy, because capsule endoscopy has certain limitations, can not completely see the intestinal tract, easy to leakage of detection, so it can not replace the colonoscopy. 2. Traditional gastrointestinal imaging: gastrointestinal imaging, abdominal CT or MRI can assess the intestinal condition, but it cannot assess the intestinal mucosal lesions, so there are all the limitations. If the patient can well tolerate enteroscopy, it is recommended to choose enteroscopy, in order to reduce the pain, can choose painless enteroscopy. The patient still does not want to do it, it is recommended to consult a doctor in time, and choose the appropriate examination under the judgment of the doctor.
