57-year-old Ms. Zhang recently felt that the frequency of defecation increased . Sometimes she even had to go to the toilet five times a day, and she had difficulty defecating almost every time, but the feeling of defecation was very strong, which scared Ms. Zhang and made her suffer from insomnia these days.
Fortunately, Ms. Zhang has the habit of insisting on physical examinations every year. When she explained her symptoms to the doctor, considering Ms. Zhang's age and medical history, the doctor suggested Ms. Zhang to do a detailed examination. At first, Ms. Zhang thought the examination was good for her and had no worries. However, when she saw that was going to have colonoscopy , she suddenly was stunned by .
"I can do any examination in , but I don't have a colonoscopy, it's too uncomfortable, I have to do it again if I fail. " Ms. Zhang suddenly became excited, and no matter how her children persuaded her, it was useless. It turned out that a few days ago, Ms. Zhang’s friend said how uncomfortable it is to have a colonoscopy. Looking at her friend’s uncomfortable expression, Ms. Zhang secretly vowed that she would never have a colonoscopy in her life.
In order to calm Ms. Zhang's emotions, I began to tell her about colonoscopy. Do you know how colonoscopy is operated ?
1. How is colonoscopy done? How painful does it hurt?
Here I would like to tell you what a colonoscopy is. In fact, a colonoscopy is a kind of snooping lens that can penetrate the specific situation inside through the natural channels of the human body. It can be understood as an slender tube with a camera and light source , which is almost as thick as our middle finger, and can be bent.
When doing colonoscopy , the doctor will use some medicine to relax the patient, and then insert the colonoscopy into the patient's anus . Then the doctor will push the tube upwards to let it enter the patient's rectum and colon, and fill it with gas to spread the mucosa folds of the intestinal cavity to better observe the shape of the mucosa surface. In this process, you can often see whether the mucosa surface is congestion, ulcers, new organisms, , etc.
The reason why most people feel uncomfortable with colonoscopy is actually because the gas filled with has a certain pressure on , and the muscles in the intestinal wall will gradually stretch. It is precisely because intestinal wall is sensitive to such pulling that the patients feel pain. Many people still think that colonoscopy accidentally causes pain, but this statement is wrong.
This pain will not last for a long time. When checks the exhaust gas, it will no longer feel pain in .
In addition, during colonoscopy, the doctor may collect a small piece of tissue from the patient's colon to perform biopsy , and observe and study the tissue samples through a microscope. This is to check whether the polyps in the patient's colon have become . Don't worry too much. During this process, the patient cannot feel the doctor's actions, so will not feel any pain .
This shows that there is a certain pain during colonoscopy, but this kind of pain is within our tolerance range . When the body develops symptoms and the doctor recommends colonoscopy, you must not refuse colonoscopy because colonoscopy is an effective means to diagnose and treat intestinal diseases. If you are really afraid of pain, you can perform painless colonoscopy at the doctor's suggestion.
2. When doing colonoscopy, doctors are most afraid of these two things
Although some patients will refuse colonoscopy because they are afraid of pain and other reasons, in order to recover from the disease, many people will pluck up the courage to have colonoscopy , but psychological acceptance does not mean that colonoscopy can be carried out smoothly. If you don’t believe it, look at what the doctor is most afraid of, you will understand, because these things may cause colonoscopy to fail .
. Patients are too anxious and afraid of
Although the effect of colonoscopy on the diagnosis of disease cannot be ignored, this test still has a certain failure rate. For example, patients with who are too anxious during colonoscopy or who are prone to anxiety in their emotions are very risky to fail. There are two main reasons.
You may not know that anxiety state is mainly used to evaluate the experience or feeling of fear, worry, tension and neurotic in a specific time or scene. By understanding the process of colonoscopy, we already know that colonoscopy is invasive because it is necessary to insert the patient's anus with colonoscopy. This foreign body sensation will involuntarily cause the patient to experience negative emotions such as embarrassment, anxiety, and fear of .
If the patient has moderate to severe anxiety , the colonoscopy may cause sympathetic nerve excitation , serum adrenocortic hormone, vasoconstriction, cortisol levels to varying degrees. The patient's heart rate may induce respiratory system and circulatory system adverse events , such as nausea, vomiting, etc. This will undoubtedly increase the difficulty of colonoscopy and the risk of failure.
On the other hand, because colonoscopy takes a long time, some patients often involuntarily disobey the doctor's requirements because of fear and unbearable pain, which will increase the difficulty of the operation and may also make themselves more painful.
Therefore, if you are too scared when you have a colonoscopy, you can calm your emotions through taking deep breaths , or think of other things to divert your attention , and you can also learn about colonoscopy to relieve tension before starting the examination, and maintain a relaxed mentality .
. Intestinal preparation is not done well
Some people may ask, What is intestinal preparation ? In fact, intestinal preparation is mainly to clear the intestines, and excrete food residues and feces inside the intestines from the body. We already know that colonoscopy requires the picture taken by the tube with a camera to determine whether there are any abnormalities inside the intestinal tube.
The food residues and feces in the intestine may cover the lesion site, especially some small polyps, inflammatory , etc., which are prone to missed diagnosis. In addition, if there are too many food residues and feces, will also block the intestinal , which will directly lead to the inability to enter the colonoscopy and the examination cannot be completed at all.
In addition, if the patient's is too old, will also affect the smooth progress of the examination.
According to a survey, the older the patient is, the higher the risk of colonoscopy failure, especially for in elderly people over 60 years old. This is mainly because as the age increases, the length of large intestine will gradually increase , which may form a lengthy large intestine. During the patient's failure to check, the large intestine is prone to become a ringworm and cause abdominal pain, which will also increase the risk of colonoscopy failure .
Some people may have questions when seeing this. Can’t you prepare the elderly for intestinal preparation? Of course, it will be done, but this requires the patient to drink a lot of water in a short period of time, which can easily cause bloating and nausea . The basic quality of the elderly is also checked. If you defecate multiple times, it may cause collapse and even hypoglycemia, which makes the intestinal clearance effect of not obvious.
Since intestinal preparation is inevitable, what should we do before colonoscopy? Is there a way to make the colonoscopy successful?
3. How can colonoscopy be successful in one go? Doctor: You must prepare the intestinal tract.
Whether it is colonoscopy, laryngoscopy, , or other types of examinations, it may fail. For colonoscopy, intestinal preparation can help you successfully check . Let’s take a look at what preparations you need to make.
Pay attention to diet
In order to ensure the quality of intestinal preparation, the liquid diet should be cleared 1 day before the intestinal examination. Do you know what a liquid diet is? In fact, a diet consisting entirely of clear liquid or semi-liquid foods is a liquid diet, such as water, juice without flesh, tea, coffee, etc.
However, be careful about to avoid eating red, purple, and blue liquid foods, because eating these colored foods into the stomach and intestines may affect the results of colonoscopy.
Although clear liquid diet is mostly regarded as a traditional diet before colonoscopy, these foods provide the human body with limited calories and nutrition. Are there any other foods? Here we have to mention low-fiber diet . It not only has the same intestinal cleaning effect as liquid food, but also can make up for the characteristics of liquid food that is not tolerant of hunger.
This is because fiber is the component of fruits, vegetables, and grains. It cannot be absorbed by the intestines , and it also promotes intestinal peristalsis, which can delay hunger to a certain extent. There are many common low-fiber foods in life, such as noodles, steamed buns, rice porridge, , etc.
Intestinal preparation method
On the day of colonoscopy, the patient cannot eat any food, and under the guidance of the doctor, he must take intestinal clearing medicine , and then he must start defecation multiple times until discharges the watery stool to meet the requirements of colonoscopy.
must prepare intestinal tract according to the doctor's requirements, because if the intestinal tract is not prepared enough, may then use enema to meet the examination requirements. Although enema will cause discomfort to the body, this is very effective for patients who do not have time to prepare or are not prepared enough.
