There is no such thing as “try not to have a colonoscopy”.
If there are indications for colonoscopy and contraindications have been ruled out, then it is best to have a colonoscopy in order to determine whether there is a substantial disease in the intestines.
Enteroscopy is a long fiber hose with a high-definition camera at the front end, which can clearly see the mucosal lesions in the intestines, and can also take biopsies under the microscope to do pathology for a clear diagnosis, or can be resected under the microscope, which is effective, less invasive, and has a wide range of applications.
Other intestinal examinations, such as gastrointestinal imaging, abdominal CT, abdominal ultrasound, etc. cannot directly observe the tiny lesions in the intestines, especially the intestinal mucosal lesions, such as intestinal inflammation, early stage of cancer, etc., which are very easy to be missed by imaging, CT, ultrasound, and so the doctor will recommend perfecting the colonoscopy.
