There are so many examinations nowadays, and colonoscopy is very uncomfortable. It is similar to gastroscopy, but the parts it passes through are different. The colonoscopy is mainly inserted through the anus, so you should not eat for five hours before the procedure. Ensure the patency of the intestines. Colonoscopy will cause abdominal bloating. This is normal and there is no need to worry too much. Try to keep a happy mood and don't have too much stress, otherwise you will feel particularly painful. Bowel preparation: Patients should take 3000ml of polyethylene glycol electrolyte powder solution 5 hours before colonoscopy (completed within 2 hours). The cleanliness of the intestine is a key factor affecting the success or failure of colonoscopy. Therefore, it is important to choose a safe and effective intestinal preparation method. The doctor inserts a thin tube with a camera lens into the intestine through the anus and continues to push it inward after insertion. Because gas may be added to expand the intestine during advancement to facilitate the entry of the colonoscope, there will be a stronger feeling of bloating in the stomach at this time. When the colonoscope reaches the examination site, both the doctor and the patient can observe the condition inside the intestine on the computer monitor nearby. If necessary, the doctor will use colonoscopy to take samples from the intestine for further biopsy. Colonoscopy is one of the safe, effective, reliable and simple methods for diagnosing and treating colorectal diseases. It can not only identify lesions that cannot be identified by barium enema X-ray examination, but also take biopsies for pathological examination and treat certain colorectal diseases. Eat a low-residue diet 3 days before the examination, a liquid diet 1 day before the examination, and fast on the morning of the examination. Cleanse your bowels with a laxative or cleansing enema the night before your exam. Colonoscopy is a diagnostic test used by doctors to examine the interior of the large intestine and colon. Generally, colonoscopy is required if there is unexplained lower gastrointestinal bleeding, unexplained chronic diarrhea, unexplained low intestinal obstruction, suspected large intestine or terminal ileum tumors, colorectal polyps, tumor bleeding and other lesions that require colonoscopy treatment. Colitis refers to inflammatory lesions of the colon caused by various reasons. It can be caused by bacteria, fungi, viruses, parasites, protozoa and other organisms, and can also be caused by allergic reactions and physical and chemical factors. The main clinical manifestations are diarrhea, abdominal pain, mucus and bloody stools, tenesmus, and even constipation, and inability to defecate for several days; it is often accompanied by weight loss, fatigue, etc., and the disease often recurs. Generally, these black spots may be caused by inflammation, and active anti-inflammatory measures can help improve the situation. |
