50-year-old Liu accepted the doctor’s suggestion and planned to do a gastroscope and colonoscopy for the first time. However, he heard that the examination would cause strong discomfort, nausea, vomiting, and intestinal colic during the process, which made him feel uncomfortable. He was looking forward to endoscopy and was afraid of being hurt. His friend comforted him and said that for painless endoscopy, as long as anesthesia is needed once, the gastroscope and colonoscopy will be solved. The process is like sleeping. Expressed doubts, still a little worried.

In the past, when gastroscope and colonoscopy were mentioned, some people did not dare to check because they were afraid of pain and discomfort, but now there is painless endoscopy, which provides another option for those who are afraid of pain-, in a comfortable sleep state, Gastrointestinal examination can be done easily.

Endoscopy facilitates detection of early-stage gastrointestinal cancers

According to relevant statistical results, gastric cancer and colorectal cancer are the top malignant tumors in China. Many patients are often at an advanced stage when the tumor is discovered, and the treatment effect is poor. Endoscopy is a powerful tool for early detection of these tumors, and if necessary, slices can be used for pathological tests to detect early gastric cancer or colorectal cancer. Some tumors can even be directly removed by endoscopy, or early With the help of surgery, it can be treated in time to avoid cancer cell metastasis.

Endoscopy such as gastroscope and colonoscopy is currently an important and necessary item for health check in some units. However, the inspection must be entered from the mouth and the anus, respectively. The flatulence caused by the inspection and the impact of the endoscopic pipeline on the stomach often make the subject painfully unbearable. In order to reduce the pain during endoscopy, painless endoscopy came into being.

Painless endoscopy, no pain in sleep state inspection

Compared with traditional endoscopy, painless endoscopy is to apply an appropriate amount of anesthetic, sedative and anti-anxiety hypnotics to the vein of the subject. The dose and type of drugs used are much lighter than those used in general surgery. Although patients may experience different feelings due to differences in physical and mental conditions and doses, they generally do not feel pain. During the process, it is like falling asleep. Even if they are not asleep, they do not feel pain. In addition to the well-known gastroscopy and colonoscopy, painless examinations also include enteroscopy and cholangiopancreatoscopy.

Compared with traditional endoscopy, painless endoscopy needs to confirm the physical and mental condition in advance. In addition, because of anesthesia, the subject’s heartbeat, respiration, blood pressure and blood oxygen concentration must be observed during the process until the subject is awake after the inspection is completed. . Painless gastroscopy and colonoscopy take about 15-30 minutes. If the two are done together, it will take about 1 hour in total from preparation, anesthesia, the end of the examination, to the recovery of consciousness after the examination.

Prep for bowel cleansing

It must be reminded that the preparation for low-residue diet and bowel cleansing (intestinal cleansing) must be thorough one day before the test. If the bowel cleansing is done well (clear liquid is discharged), the inspection is half the success, which is helpful for clear detection. Polyps; may have to be re-cleared if the bowel clearing is not complete (fluid liquid stools or formed stools).

As for whether the accuracy rate of painless endoscopy is higher than that of traditional endoscopy, although there is no specific data to confirm it, from the feeling of clinicians and subjects, because the patient is performing the examination in a comfortable state, the doctor is in a comfortable state. The operation process will not be disturbed, the diagnosis can be carried out smoothly, and more lesions can be found.

Not suitable for people allergic to anesthetics

However, painless endoscopy is not suitable for everyone, such as those who are allergic to anaesthetics, have a history of chronic diseases such as obstructive pulmonary disease, heart disease, aspiration pneumonia, and those with weak resistance, which may increase the risk. Doctor evaluation. On the contrary, if the abdomen is sticky or the intestines are curved, it is most suitable for painless endoscopy. The most painful time for traditional colonoscopy is when the endoscope is going to pass the curve, because the intestines are pulled. Colic caused by nerves, especially when the colonoscope enters the cecum from the anus, the length is more than 1 meter, and the bending in just a few seconds can make some people with sticky abdomens unable to do it.

Therefore, endoscopy is a technology-oriented examination. The doctor’s experience and skills determine the quality. Usually, unless the subject is unable to perform due to intestinal adhesion or incomplete bowel cleansing, doctors with good skills generally face traditional endoscopy. , even when cornering, the subjects will have no obvious pain, and the completion rate can reach 99%.

If you are over 50 years old, you should have regular bowel and gastroscopy examinations

As for how often to do the relevant examinations, it depends on whether they belong to high-risk groups. Generally, people only need to have a gastroenteroscopy examination at the age of 50, and they can do it once every 3 to 5 years. Medical history or patients with ulcerative colitis are all high-risk groups. Not only the age of examination should be carried out before the age of 40, but also regular follow-up. In addition, I am a patient with breast cancer, ovarian cancer and colorectal cancer, and the risk of gastrointestinal cancer is also increased, so I am also a high-risk group.

Domestic and foreign application experience does not increase the probability of intestinal perforation

The safety of anesthesia for painless endoscopy has been discussed in China. For a long time, people’s traditional concept is that pain is a warning signal, and pain is to be endured for examination, so anesthesia cannot be used, even in the medical field, More than 20 years ago, I also held this concept, thinking that painless endoscopy would increase the risk of intestinal perforation. In fact, these concepts are not correct. The risk does not come from anesthesia, but endoscopy is an invasive examination. Indeed It may cause gastrointestinal perforation and bleeding, etc., but the probability is extremely low. Painless endoscopy has been carried out in Europe and the United States for many years. This is to provide the subjects with a comfortable medical quality. Relevant reports in the United States show that painless endoscopy is performed. There is no increased risk, no reported complications, but less pain.

I heard that anesthesia is used during painless endoscopy, so the subjects are prone to talking to themselves during the examination?

This phenomenon is rare, because after anesthesia, he usually falls asleep within 10 seconds, and at most he may hear the speech of the people around him, and he is unconscious.

Wouldn’t it feel good to have a biopsy during an endoscopy?

yes. When abnormal tissue is found and sliced, there will be slight bleeding, but the patient will not notice it and will not feel pain. Since the wound will automatically coagulate, there is no need to stop the bleeding or suture, as long as the observation confirms that there is no more bleeding .

Wouldn’t it feel like if the gastrointestinal tract ruptured during the examination? What should I do if this happens?

Depends on the degree of gastrointestinal rupture. If the wound is small, the wound can be clamped with an instrument clip, which is equivalent to closing the hole. After a few days, the instrument clip will automatically drain from the anus, and the patient will not feel uncomfortable. If the ruptured stomach is too severe, surgical suturing may be required, but this is a rare occurrence during examinations, usually only with therapeutic endoscopy.

Is there any danger of not waking up after anesthesia?

Won’t. Because the dose of anesthesia drugs is very low, the patient only enters a short-term sleep state, as long as it is not a high-risk group who is not suitable for anesthesia, there is no need to worry about this problem.
