Let's take a look at the most comprehensive colonoscopy science in history!

.

First, let's take a look at what a scene is.

The so-called colonoscopy is to slowly insert a flexible hose with a lens into the patient's intestinal cavity through the anus, observe the specific lesions in the intestinal cavity through the lens, and directly take out the diseased tissue through the colonoscopy for pathological examination. Colonoscopy is the simplest, safe and effective method to find intestinal tumors and precancerous lesions, and it is the gold standard for colon cancer examination.

Why do you want to do colonoscopy?

Regular colonoscopy is of great significance for early detection and prevention of colon cancer. Although not all polyps will develop into cancer, most colorectal cancers are developed from polyps. Colonoscopy can be used to find and remove polyps and prevent them from becoming cancerous. Especially, if the lesions are found in the early stage of intestinal cancer and removed in time, the 5-year survival rate of patients can reach more than 90%.

What is the process of colonoscopy?

Before intestinal examination, it is necessary to prepare the intestine so that doctors can observe the internal situation of the intestine through colonoscopy. If there is residual stool, it is not clear. The requirements of general hospitals are to start a diet with less residue three days before the examination, try to eat some digestible foods, such as rice porridge and soft noodles, and avoid eating fibrous foods such as leeks, celery and Flammulina velutipes. If you make an appointment for morning check-up, you should fast or eat liquid food (such as clear soup and white sugar water, but you can't drink milk, soybean milk and thick soup. ) At dinner the night before, and at 6-7 p.m., it is best to take the intestine-clearing agent to discharge clean water and feces. If there is still fecal residue in the discharge, you need to continue drinking water. If you make an appointment for a physical examination in the afternoon, you should fast breakfast on the day of the physical examination and take a laxative in the morning. If the intestinal tract is not thoroughly cleaned, it is feasible to clean enema or large intestine hydrotherapy 65438+ 0-2 hours before examination. You need to defecate once before entering the examination room. It should be noted here that if you make an appointment for painless colonoscopy under anesthesia, you need to ensure that you drink alcohol on an empty stomach for more than 6 hours before the examination; Those who are inspected in the morning will be fasted and forbidden from 0: 00 on the inspection day, and those who are inspected in the afternoon will be fasted and forbidden from 9: 00 on the inspection day.

What does colonoscopy feel like? Will it hurt?

In the process of colonoscopy, in order to let the endoscope enter the intestinal cavity smoothly, the doctor will inflate the intestinal tube from time to time. Only when the intestinal tube is opened by gas can the specific situation of the intestinal cavity be clearly observed. Therefore, patients can feel obvious abdominal distension at the beginning of inflation, and general patients will gradually adapt to this feeling under the guidance of doctors. In addition, because the intestine is curved in the abdominal cavity, patients will feel pain when the colonoscopy enters every "bend". This kind of pain is related to the bending of the intestine, the operation of the doctor and the sensitivity of the patient. Therefore, different patients feel different pain during colonoscopy, even if the same patient is in the same colonoscopy operation, the pain will be different with the position of the endoscope. Also, in the general colonoscopy, some patients will be very nervous, and with the continuous expansion of the intestinal cavity, patients will have a strong sense of defecation and exhaust. At this time, the patient must relax and leave the hospital boldly, so as to avoid intestinal spasm due to nervousness and hinder the continuation of colonoscopy. Ordinary colonoscopy 10 to 30 minutes can be completed, while painless colonoscopy usually takes 30-40 minutes or even longer from anesthesia to awakening.

Finally, what should I do if I find something abnormal during colonoscopy?

If polyps are found during colonoscopy, the doctor may remove them during the examination. If the polyp is very large, or other suspicious lesions such as tumors are found, the doctor will take out some or all of the diseased tissues and send them to the laboratory for testing. The Department of Pathology will give an examination report after 3-5 working days to inform the patient of the nature of the lesion.
