How long is the “validity period” for a colonoscopy? the doctor tells you the answer

Introduction: A deputy director of the gastroenterology department once said that 13 of the 14 people who had clinical contact with colonoscopy were cancerous. Those with previous lesions, and one will be diagnosed with colorectal cancer.

Colorectal cancer is a very common malignant tumor in the digestive tract today,Its incidence The rate ranks third in the world, while the death rate ranks fourth in the world.

Especially in recent years, the incidence of colorectal cancer in my country has been increasing year by year. The number of new colorectal cancer patients in China can reach 400,000, accounting for about 1/4 of the global total.

The reason why my country’s colorectal The incidence of cancer is increasing year by year, which is mainly related to lack of exercise and changes in diet structure. Therefore, if you want to better prevent colorectal cancer and other problems, you first need to improve your diet structure and do physical exercise properly. In order to better improve immunity,help prevent colorectal cancer from appearing.

The average age of colorectal cancer patients in Europe is about 65 years, while the average age of colorectal cancer patients in China is 56 years old, which is 10 years lower than that in Europe.

This is mainly because our country has not yet established a national screening plan ,The detection of colorectal cancer patients in China is relatively late. A considerable part of rectal cancer cannot be operated on with the anus preserved, so it is necessary to carry out corresponding procedures Colonoscopy.

Why do many doctors recommend colonoscopy?

In fact, in daily life, most people are not particularly clear about colonoscopy, so I also feel particularly afraid of this project, so I also choose to evade this inspection.

In recent years, the incidence of colorectal cancer and other cancers has been increasing. This kind of cancer is controllable and preventable.In particular, it takes about 5 to 10 years for intestinal polyps to develop into colorectal cancer.

Colonoscopy can detect possible problems in the intestinal tract early, and then It can reduce the occurrence of colorectal cancer and other problems, especially for high-risk groups of cancer, colonoscopy is particularly critical.

according to Relevant surveys and studies have found that passing colonoscopy can reduce the risk of death from colorectal cancer by about 61%, compared with those who have undergone colonoscopy in time and those who have not undergone colonoscopy span>, the risk of colorectal cancer decreased by 51.3%.

Moreover, the penetration rate of colonoscopy in my country is particularly low, while in some European and American countries people over 50 years old The honesty inspection rate can reach more than 65.3%, and the death risk of colorectal cancer and other cancers has dropped by about 55.8%.

However, the colonoscopy examination rate of people over 50 years old in my country is less than 16.3%, so it is fundamental There is no way to keep abreast of the internal condition of the intestinal tract, which leads to an increase in the incidence of colorectal cancer,So this testChecking is particularly critical.

How long is the “validity period” for a colonoscopy? The doctor will tell you the answer

Perhaps most people don’t know much about colonoscopyIn fact, colonoscopy The properties of endoscopy and gastroscopy are similar, but the entry sites of the two are different.

When performing a colonoscopy, it is generally necessary to enter the intestinal tract through the patient’s anus Corresponding inspections are carried out internally, and the doctor must also perform detectors.

After the probe probe enters the large intestine of people, it can clearly check whether there are polyps or It is other lesions.If polyps are found, they can be removed in time.

Generally, the validity period of colonoscopy is about 5~10 years, but this cannot be generalized, because every People’s physical fitness is not the same, so the expiration date is also very different.

For some people with light diet and regular diet, it is rarely easy to appear Gastrointestinal diseaseSo everyone can have a colonoscopy every 10 years.

But for those patients with chronic gastroenteritis or intestinal diseases,< /span>You can have a colonoscopy every 3 to 5 years, which can effectively prevent the disease from getting worse.

Then why does it have to be a colonoscopy, can’t other checks work?

When it comes to scenes in life, many people’s first reaction is fear, and they don’t want to have this examination at all. It will feel particularly resistant from the inside out.

Because the colonoscope is very intuitive to observe the intestinal tract< /strong>At the same time, it can also perform biopsy of lower intestinal lesions and related treatment, so compared with screening methods such as fecal occult blood and abdominal CT.

Colonoscopy can detect lesions earlier, and can also kill tumors in the bud span>, so early colonoscopy is the core of cancer prevention, especially colorectal cancer.

Colonoscopy is so important, why are many people unwilling to do it?

There are so many benefits of colonoscopy, why are many people still reluctant to do it? In fact, in the final analysis, there are mainly two points:

1. Fear of colonoscopy

Colonoscopy may be prone to related symptoms such as abdominal distension and abdominal pain. In fact, you don’t need to worry too much. With the progress and development of the times, many hospitals will perform painless colonoscopy, Generally, there will not be too strong pain during colonoscopy; /strong>

2. I think colonoscopy is a waste of money

Many people do not have the concept of early screening, thinking that since I have no uncomfortable symptoms, So doing a colonoscopy on the basis that I’m not sick is a waste of money.

In fact, we all need to understand that many cancers do not have any symptoms in the early stage. Go to the hospital for an examination when you have symptoms, and the final results may not be satisfactory, and it is very likely that you have already reached the middle and late stages.

When do you need a colonoscopy?

  1. Patient with unexplained low intestinal obstruction;
  2. < li data-track="37">Patients with unexplained middle and lower abdominal pain;

  3. < span>Patients who need to determine the extent of lesions before colon cancer surgery, re-examine after polyp surgery, and re-examine after colon cancer surgery;
  4. < span>Abdominal masses with unknown causes;
  5. Patients who need to further identify the nature and scope of intestinal lesions;
  6. Patients with unexplained lower vena cava bleeding;
  7. Patients with unexplained chronic diarrhea;
  8. < span>People over the age of 45.

What needs to be done before colonoscopy?

The preparation for colonoscopy is divided into two parts,One is diet, the other is taking laxatives .

1. Meal preparation:This includes the first three days before the colonoscopy, try to avoid eating some high-check, high-fiber or colored foods, and these foods include corn, fungus, tomatoes, mushrooms, etc., because these foods have obvious color, and their shells are difficult to digest, so they generally exist in the intestinal tract in the form of prototypes, which will affect the observation of lesions;

2. Taking laxatives:If you have a colonoscopy in the morning, it is recommended that you take half of the laxatives the night before the examination. Drink it, then take the other half of the laxative the morning of the test. The specific usage should also follow the individual’s physique and doctor’s advice.

Conclusion: Generally speaking, the incidence of colon cancer is increasing year by year, and the difficulty of treatment in the middle and late stage is also If it is very large, it will pose a threat to people’s life and health, so everyone must pay attention to it in daily life, do a good job in related prevention work, perform regular colonoscopy examinations, and seek medical treatment as soon as possible when there is an abnormality in the body.
