Can capsule endoscopy replace colonoscopy?

Whether capsule endoscopy can replace enteroscopy should be analyzed according to the actual situation.

If the patient has small intestinal bleeding, Crohn's disease, etc., the small intestine can be examined by capsule endoscopy. The image of the digestive tract can be taken and transmitted to external equipment for analysis and diagnosis by wireless transmission. It can replace enteroscopy. If the patient has rectal polyps, colorectal cancer and other diseases, capsule endoscopy cannot carefully examine the rectal lesions at this time, and colonoscopy is needed to observe the condition of the large intestine wall, and biopsy, polypectomy and other treatment operations. At this time, capsule endoscopy generally cannot replace colonoscopy.
