In the anorectal department of the hospital, when most patients hear "colonoscopy", the knee-jerk reaction is: refuse!
There are two main reasons why patients do not want to do colonoscopy, the first is that they have heard in life that doing colonoscopy will produce pain and discomfort, and they are afraid and unbearable.
Second, colonoscopy needs to expose private parts, which makes it difficult for many patients to accept in their hearts and produce a shy mentality. In addition to these two major reasons, some patients will also give up colonoscopy because they are worried about the cost!
As everyone knows, although colonoscopy is an imaging examination, it is different from other impact examinations.
Because colonoscopy is mainly aimed at the screening of the intestine, it should be known that the intestine is originally a cavity organ, and the lesions that occur in the intestine may initially be mucosal erosion and color changes, even if there are polyps and cancer formations, it is difficult to cause symptoms.
Ordinary CT examination and ultrasound screening are difficult to penetrate the abdomen to find lesions. But colonoscopy is completely different, because it transports the fiber hose with camera to the large intestine through the anus, and the most direct observation of the rectum and colon mucosa can detect subtle lesions.
If a suspicious lesion is found during the examination, the doctor will also take the tissue for pathological biopsy by the way, so this examination item is of great significance for the diagnosis of various intestinal diseases.
From a clinical point of view, if the age is more than 50 years old, there are long-term stool abnormalities (blood in the stool, changes in the stool pattern, abnormal stool shape), lower abdominal pain, bowel cancer or family history of polyps, colonoscopic screening should be carried out, so as not to miss the best diagnosis and treatment of the disease.
So the question is, how long does colonoscopy take, and what preparation should be done?
First of all, the colonoscopy itself does not take too long, and the doctor can complete the examination in about 20 minutes. However, colonoscopy itself is an invasive means of examination, so before the examination, the patient needs to carry out several days of preparation, completely empty the intestine, in order to smoothly carry out the examination, especially the following two points can not be ignored:
1. Dietary adjustment
Usually when examining the colonoscopy in the hospital, it is often necessary to queue up for appointments, especially painless colonoscopy appointments, which take a certain amount of time.
After the appointment is successful and the specific date of the colonoscopy is determined, all the patient has to do is to adjust the diet, usually starting 3 days before the colonoscopy, the patient should choose some residue-free, dregs-less liquid foods, such as rotten noodles, steamed eggs, white rice porridge, etc., and the patient should try to avoid eating vegetables and fruits.
It should be emphasized here that patients who may need electroresection if there is a suspicion of intestinal polyps should abstain from milk and dairy products for 3 days before the examination;
2. Emotional adjustment
I have to say that after all, colonoscopy is an invasive examination method, and the fiber hose needs to enter the colon through the rectum for examination, so the ordinary colonoscopy will indeed produce discomfort in the process of being carried out, and the discomfort will be more intense for people who are more sensitive to pain.
However, we must understand that this kind of examination requires the dual cooperation of doctors and patients, so patients should relax their mentality and adjust their personal emotions. If you are too afraid of colonoscopy, you can consult a doctor in advance, and if your own conditions permit, you can choose a painless colonoscopy for examination.
Finally, we should remind everyone that after adjusting the diet and doing good psychological construction, in order to make the colonoscopy more smooth, in the night before the examination, the patient needs to take relevant laxatives and intestinal lavages, and take them within a few hours according to the doctor's recommendations.
After that, the patient should observe the discharge of feces, if the stool has become a yellowish transparent liquid, there is too much residue, it means that the debris in the intestine has been cleaned up and colonoscopy can be performed.
