Can colonoscopy examine the small intestine?

Colonoscopy is also a widely used intestinal examination procedure, and colonoscopy mainly uses an endoscope to insert into the human anus to detect lesions in the colon and large intestine inside the anus. There are many types of diseases that can be detected by colonoscopy, such as colorectal polyps, colorectal tumors, etc. But if a person has a problem with their small intestine, can they detect it through colonoscopy?

Colonoscopy is to observe the internal condition of the human colon and large intestine, that is, to check whether there are any lesions inside the human colon and large intestine. If you have diseases such as colorectal polyps, gastrointestinal bleeding, malignant tumors, or some chronic enteritis, you can choose to have a colonoscopy. You can only eat some liquid food starting from the three days before the colonoscopy, and you need to take castor oil orally on the day of the examination and you cannot eat breakfast. When starting a colonoscopy, you need to use intestinal fluid to clean the large intestine. Only after it is clean can the examination be performed. A colonoscopy usually takes about half an hour, and the patient needs to sleep on his left side during the examination. A colonoscopy may cause abdominal distension or bloody stools, but it is not very harmful to the person being examined.

Enterography is an X-ray examination of the small intestine. This examination is very effective in diagnosing some small lesions. In addition, it is very effective in diagnosing some small depressed lesions. Conditions such as gastrointestinal bleeding, diarrhea, abdominal pain, tumors, small intestinal adhesions, etc. can all be treated with small intestinal angiography. However, you can reduce the intake of some indigestible foods one or two days before the small intestine radiography examination, and some high-atomic-weight drugs should not be taken. You need to fast and not drink water the day before the examination, and you need to take barium sulfate suspension on an empty stomach one or two hours before the examination. Enterography may cause some complications, such as severe pain in the lower limbs, increased intestinal water absorption, abdominal distension, bloody stools, etc.

Enteroscopy and colonoscopy are different in terms of the objects of examination. Enteroscopy is used to examine the condition of the small intestine, while colonoscopy is used to examine the condition of the large intestine and colon. The examination methods of the two are also different. Enterography is performed through X-rays, while colonoscopy is performed through an electronic photographic tube. In addition, there are certain differences in the scope of application. Enterography is mainly used for some diseases of the small intestine, while colonoscopy is used for some diseases of the large intestine and colon. In addition, there are certain differences in the examination methods of small enterography and colonoscopy, as well as the complications caused after the examination.
