Is it dangerous to have a colonoscopy, and are there any sequelae or side effects?

Colonoscopy is an invasive test that can lead to complications.

Although colonoscopy has been used in clinical practice for decades, the safety profile is very high. However, complications can still occur if it is not used properly or if the operation is more complicated. According to clinical statistics, the incidence of complications is very low, and the complication rate of monoscopy alone is only 0

32%, while the complication rate was significantly higher when some ** was done under colonoscopy, which was 2

3%。The most common complications are local complications caused by direct contact with the colonoscopy, such as gastrointestinal bleeding, intestinal perforation, etc., or intestinal infections due to poor disinfection. Gastrointestinal bleeding is mostly mucosal bleeding due to biopsy or polypectomy, and most of it stops spontaneously.

Gastrointestinal perforation is mainly caused by the following two reasons: first, improper operation to puncture the intestinal wall, biopsy or polyp removal of tissue too deep; Second, the intestinal wall itself is damaged by the lesion of the intestinal wall, and if it is overinflated during colonoscopy, the pressure in the intestinal lumen increases suddenly and the intestinal lumen becomes perforated. Perforation is a serious complication that should be treated as soon as possible and may even require surgery**.

In addition, some complications do not occur until months or even years after colonoscopy**, such as narrowing of the intestinal lumen due to scar contraction after the removal of a broad-based polyp.

There are some complications associated with winter management, but colonoscopy is still a safe procedure. As long as its complications are treated promptly and effectively, most patients can be treated completely**.

Colonoscopy does not cause great harm to the body. Colonoscopy is about 1 cm in diameter, can be bent, and generally does not cause harm. However, some patients may have intestinal flatulence and bleeding after colonoscopy, but they can be relieved by resting for a few hours.

Colonoscopy can visually observe intestinal lesions, and can detect malignant changes early and give **. Frequent colonoscopy does not cause great harm to the body.

Instead of waiting for the body to have symptoms, colonoscopy can be done at a regular time, which has a great effect on the prevention of colorectal cancer.

Do I need to be hospitalized for colonoscopy? What are the possible harms?

If the child's digestive function is obviously abnormal, the stool is persistently unformed, the stool is loose or even more mucus, and there is bleeding, colonoscopy can be considered, and there is no need to be hospitalized after completing the colonoscopy. Colonoscopy is a common examination item, which can mainly see the specific conditions of the human gastrointestinal tract clearly and intuitively. If there are gastritis, gastric ulcers, intestinal polyps, tumors and other corresponding conditions, you can do it as soon as possible**.

After colonoscopy, a small number of patients may have symptoms such as blood in the stool and black stool, which is relatively common. Colonoscopy can be done in an outpatient or inpatient setting. However, whether to be hospitalized for colonoscopy should be comprehensively analyzed based on medical history, clinical symptoms, and underlying diseases.

Before colonoscopy, hepatitis B surface antigen and an electrocardiogram (ECG) are usually tested to determine whether a colonoscopy is a good candidate for colonoscopy. If you confirm that a colonoscopy is a good candidate, you will need to do some preparation before the colonoscopy. The most important thing is to empty the bowels.

During preparation, the intake of crude fiber should be reduced to reduce food debris and feces, otherwise the visual field will be affected. In good physical condition if there are no clinical symptoms or underlying disease. Electronic colonoscopy, which does not require hospitalization, can be performed on an outpatient basis.

If the patient has clinical symptoms such as blood in the stool, abdominal pain, increased frequency of stool, high blood pressure, heart disease, etc., the body is relatively weak. Because colonoscopy requires bowel cleansing, considering that it is not safe to drink bowel cleansing drugs at home, it is recommended that patients be hospitalized for examination. You can do a general colonoscopy or you can do a colonoscopy.

Hospitalization is generally not required. Hospitalization is generally selected when the physical condition is poor and colonoscopy is not tolerated.

The above is a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

Colonoscopy generally does not appear to do anything***, now**colonoscopy is carried out under anesthesia, and colonoscopy needs to be cleaned before colonoscopy.

mucosal ulcers, etc.

If it is ** colonoscopy, it is necessary to complete the electrocardiogram and other related examinations before the colonoscopy, and then ask the anesthesiologist for consultation, and then perform colonoscopy after general anesthesia, and the steps are the same as ordinary colonoscopy.

Considering hemorrhoids, rectal polyps, anal fissures, rectal tumors, etc., it is recommended to visit the anorectal department for a clear diagnosis. Keep the area clean and dry, and surgery if necessary.

It will cause some damage to the body.
