Why does colonoscopy hurt so much?

What is a colonoscopy? Colonoscopy is a tube inserted from anus, from rectum to cecum, with a length of about 100 cm. Its structure and function are basically similar to those of gastroscope. Colonoscopy is more troublesome and painful than gastroscope. A complete colonoscopy takes an average of 10 minutes, which is relatively easy for people with straight intestines and can be completed in 5 or 6 minutes. It may take a doctor 30 minutes to complete the examination of people whose intestines are turning or even knotting.

Who needs colonoscopy?

People over the age of 40 have a high probability of developing colorectal cancer. Therefore, over 40 years old, regardless of gender, should do a complete colonoscopy, a thorough look, not just a part of the examination.

In addition, high-risk groups should also undergo colonoscopy. Some family members have had colorectal cancer, such as parents or siblings, or colorectal polyps, or colorectal cancer, and they are still following up after surgery. Are all high-risk groups.

Colorectal cancer and rectal cancer are on the rise year by year. In the past, people were mostly simple fruits and vegetables, and there were few fish and meat. Modern people's high-fat and high-fat diet has brought a heavy burden to the stomach. Intestinal cancer can be said to be a typical civilized disease. Although recent research shows that eating more fiber-rich foods may not necessarily prevent intestinal cancer, most doctors still recommend eating more fiber-rich foods and eating less red meat, plus moderate exercise to strengthen metabolism. People over 40 and high-risk groups should have regular checkups.

Colonoscopy must be done when there are the following symptoms: long-term chronic diarrhea or unexplained constipation; Unexplained hematochezia; There is a tumor in the abdomen that needs a definite diagnosis; The causes of emaciation and anemia are unknown; X-ray barium enema suspected colon lesions; Surgical treatment under colonoscopy (such as polypectomy). ); Follow-up after colorectal surgery and so on.

Because the length and circuitous length of colon are longer than that of digestive tract, colonoscopy has more complications than gastroscope, such as abdominal distension, intestinal bleeding, intestinal perforation, intestinal tear, cardiovascular accidents and so on. Therefore, colonoscopy is not suitable for patients with the following diseases: peritonitis, intestinal perforation and extensive abdominal adhesion; Advanced cancer with extensive intra-abdominal metastasis; Acute inflammatory lesions around rectum, anal canal and anus; Active period of bacillary dysentery; Suffering from serious cardiovascular and cerebrovascular diseases, unable to tolerate examination, etc.

Does colonoscopy hurt?

Patient Yang, male, 45 years old, was hospitalized for one year because of bloody stool. At the beginning of the disease, he refused to undergo colonoscopy for fear of pain. After admission, colonoscopy diagnosed rectal cancer and found spinal metastasis. Eight months after the operation, he died of extensive metastasis of cancer. We know that some colon cancers can be prevented. Many colon cancers originate from colonic polyps (a benign lesion). If the polyps are removed by manual intervention at an early stage, the occurrence of cancer can be completely avoided. But why do people like Yang find that colon cancer is advanced? One of the important reasons is that they have a wrong idea that colonoscopy is painful and delays the precious time of early detection, early diagnosis and early treatment. Is colonoscopy really that painful? Most people will say that listening to others talk about colonoscopy is extremely painful, so they have a sense of fear. However, with the rapid development of modern endoscopic equipment and the maturity of endoscopic examination technology, many people smile and say, that's it. A few patients even fell asleep happily and completed the examination unconsciously. Most patients said that they would like to undergo colonoscopy again if necessary. To analyze the main causes of pain during colonoscopy: 1, flatulence and hydrops; 2. The intestines are pulled; 3. Adhesion exists in the intestine itself (such as after abdominal surgery); 4. Patients are nervous and have low pain threshold, so they are naturally afraid of pain. In addition, everyone's situation is different, and the longer and deeper the intestines, the more uncomfortable they will be. Some people's intestines are bent, and it's hard to turn them around several times. Of course, it hurts. Therefore, experienced endoscopists can deal with the above reasons in a targeted manner. Tell the patient to make careful intestinal preparation according to the doctor's requirements and try to drain the stool as much as possible. Understand whether the patient has a history of abdominal surgery, fear of pain on weekdays and so on.

If you are really afraid of pain, our hospital has also carried out painless colonoscopy, which allows you to complete colonoscopy unconsciously. What should I pay attention to in colonoscopy?
