Colonoscopy is a commonly used endoscope used to diagnose diseases of the colon and rectum, also known as colonoscopy. By slowly sliding the colonoscope through the anus, the intestinal mucosa of the rectum, sigmoid colon, descending colon, transverse colon, ascending colon, cecum, and terminal ileum can be observed. The farthest part that can be seen through a colonoscopy is where the small intestine joins the large intestine. Colonoscopy is a crucial tool when diagnosing colon and rectal diseases.
In order to ensure the effectiveness of the examination, the preparation of the intestines for cleansing is key. If the bowel is not prepared adequately, the intestinal residue will affect the doctor's judgment and increase the risk of missing the disease, and the bowel may need to be reprepared and re-examined. Therefore, it is crucial to understand the importance of bowel preparation. Comparison of bowel cleansing preparations (the following pictures may cause discomfort)
Before undergoing a colonoscopy, patients need to pay attention to the following:
1. Diet:
Patients need to start eating a light, residue-free, semi-liquid diet the day before the examination.
2. Medication Use:
Patients who require bowel therapy should be directed to stop taking anticoagulants for at least a week. Compound polyethylene glycol electrolyte powder (Heshuang) is a commonly used laxative (currently in use in our hospital), and it should be taken according to the prescribed method and dosage. Oral laxative (2 bags) at 5 a.m. on the day of the examination, how to take it: 2 bags + 2000ml of warm water, 250ml of oral administration each time, 10 minutes apart each time, take 2 bags in divided doses, until it is pulled to watery stool. If you have constipation, take 1 sachet after dinner before the examination, 1 sachet + 1000ml of water, 250ml of oral administration each time, 10 minutes apart, and take it in divided doses. Laxatives should not be mixed with any other substance. Walk around properly and gently rub your abdomen after taking the medicine to speed up excretion.
3. Bowel Preparation Assessment:
Qualification of bowel preparation can be judged by comparing with the relevant criteria.
If you don't have a clean bowel movement the next day, you may need an enema, additional laxatives, or a postponement of the test, depending on the situation.
4. Other precautions:
Colonoscopy is prohibited in women during menstruation and pregnancy. Patients who have just undergone a GIG should have a colonoscopy after 3 days. Patients requiring treatment should be discontinued one week earlier and follow other requirements.
5. Positioning during colonoscopy:
During colonoscopy, the patient's position should be comfortable for the surgeon to operate and observe.
After completing the colonoscopy, patients need to pay attention to the following:
1. Symptoms of bloating and abdominal pain may occur after the examination, which are caused by injecting air during the operation, and usually do not require special treatment, and can be relieved after natural gas (stool).
2. Eat only after the bloating has been relieved, and eat a light and easy-to-digest diet on the day of the examination.
3. For patients with abdominal distension, severe abdominal pain or more bleeding after biopsy, they need to be hospitalized for observation for 1-2 days to avoid complications.
4. If you have severe abdominal pain, blood in the stool and other symptoms within 1-2 days after the examination, please go to the hospital for medical treatment in time.
5. For patients who undergo pathological examination during the examination, please go to the pathology department to collect the pathological diagnosis report within the specified time. 【Department of Internal Medicine, Zhang Lijie】
