What are the precautions before doing colonoscopy?

Before doing a colonoscopy, you must pay attention to certain precautions and principles, because any details will affect the success or failure of the colonoscopy. For example, you must keep the intestines clean before the examination, and you can take laxatives orally to help excrete and clean the intestines.

Intestinal cleansing

Intestinal cleanliness is one of the key factors in the success or failure of colonoscopy. If there is still a lot of feces in the intestines during the examination, it will affect the insertion of the endoscope and observation, and may even make it impossible to complete the full colon examination. Therefore, it is very important to clean and prepare the intestines before examination. Oral diarrhea medicine is one of the most commonly used, most reliable and safest methods in clinical practice.

Bowel preparation at home

Since the vast majority of outpatients perform bowel preparation at home, how to perform safe and effective bowel preparation at home is an issue of great concern to patients and their families.

Contraindications

Patients with the following conditions are temporarily not suitable for colonoscopy:

1) Severe suppurative inflammation of the anus and rectum, such as perianal abscess, or painful lesions such as anal fissures. Because conducting an examination under these circumstances may lead to the spread of infection, causing unbearable pain to the patient, etc.;

2)

Various acute enteritis, severe ischemic diseases and radiation colitis, such as active bacillary dysentery, acute stage of ulcerative colitis, especially the fulminant type. Because in the case of intestinal inflammation, edema and congestion, the intestinal wall tissue is thin and the compliance is reduced, which makes intestinal perforation more likely to occur;

3) During pregnancy, the indications should be strictly followed and the examination should be performed with caution. It is generally not advisable to perform the examination during menstruation to avoid ascending infection;
