colorectal cancer is one of the few cancers that can be prevented through inspection. Unfortunately, even though we have a colonoscopy, an efficient and safe way to prevent colorectal cancer, many people still hold the belief that the inspection process is uncomfortable, Embarrassing” old-fashioned ideas, missed opportunities for early detection. In response to the above-mentioned problems, Tsuen Wan Hong Kong Security Co., Ltd. has adopted improved colonoscopy technology to allow the public to receive inspections with peace of mind.
The number of bowel cancer has been increasing year by year.
In recent years, the number of cases of bowel cancer has continued to rise in countries around the world. Its incidence and mortality are ranked second among all cancers in Asia and even in Hong Kong, second only to lung cancer. In 2005, there were nearly 4,000 new cases in Hong Kong, which is a cause for concern.
Statistics show that about 85% of bowel cancers are derived from intestinal polyps. As for the cause of intestinal polyps, it is not fully confirmed. It is estimated that it may be related to the bad eating habits of “high fat and low fiber, more meat and fewer vegetables”.In addition, a small number of bowel cancer cases are related to heredity, and the risk of developing the disease increases with age.
The evolution of bowel cancer from polyps to cancer takes about ten years. Therefore, as long as polyps are detected in this “golden decade”, they can be eliminated immediately before they deteriorate. Because bowel cancer is preventable cancer, the medical community has advocated for the public for many years to minimize its threat through bowel cancer screening.
Colorectal cancer screening
There are two main items for the screening, one is a fecal occult blood test, and the other is a colonoscopy. However, due to the low sensitivity of the occult blood test, it can only detect early colorectal cancer and cannot confirm the polyps in the intestine. Therefore, the most effective examination method at present is colonoscopy.
During a colonoscopy, the medical staff will use a fiber-optic tube with microlens at the end to penetrate the tester’s anus, and the lens is connected to the display screen in the operating room. The doctor can observe the tester’s large intestine from the image, such as Polyps are found and can be removed immediately.
The incidence of colorectal cancer is at the age of 50 and above. Therefore, the public should have a colonoscopy every ten years after the age of 50. However, in Hong Kong, there are not many people who take the initiative to undergo colonoscopy. Ninety -five percent of the examiners are diagnosed with bowel cancer because they have developed bowel cancer.
The reasons for resisting colonoscopy are the pain and embarrassment of the examination process. It is said that the examination is difficult, because during the examination, the medical staff will insert a long tube into the anus, and to make the bowel distended to facilitate the examination, they will also blow air into the bowel. Feeling unwell, and the swelling feeling of “belly gas” will last for 20 minutes to half an hour. In addition, patients must drink a lot of water before the test to expel intestinal waste.
The new technology of colonoscopy to reduce discomfort
Tsuen Wan Gangan understands the above concerns of patients, so he has actively improved the technology of colonoscopy to reduce the discomfort and anxiety of patients. First, the doctor can use a deep sedative if needed, with the assistance of an anesthesiologist.
As for the discomfort of “air entering the intestines”, a new method can be used to relieve the discomfort – instead, the carbon dioxide that is more easily absorbed by the human body is injected. Since carbon dioxide “comes quickly and goes quickly”, it will not “stay” in the abdomen, relieving bloating.
We also applied the improved “colon washing” method, allowing the testers to drink about 90cc of concentrated syrup before the examination, and then drink a few cups of water, which can replace the previous “full water” bowel washing effect (the elderly, Heart or kidney disease, and liver cirrhosis patients should not be used).
Therefore, as long as you can relax before the test and cooperate with the new colonoscopy technology in our hospital, the patient can complete the test in a short time and stay away from the threat of colon cancer.
