Colonoscopy is always necessary for the diagnosis of colorectal diseases. However, colonoscopy will appear intestinal perforation, bleeding, intestinal tears, etc., many patients are talking about “mirror” fear. Yesterday, Dr. Pan Wensheng, chief physician of the Department of Gastroenterology at the Second Hospital of Zhejiang Medical University, told reporters that the colonoscopy manipulated by a single person, through the skillful doctor, can make the patient painless, but also greatly reduce the incidence of complications. The colonoscope is difficult to “wander” in the large intestine Colonoscopy is first filled with air into the large intestine, making it hollow tube. A 1.2 cm-1.4 cm thick fiberoptic tube is then used to penetrate deep into the large intestine. The tube is equipped with a miniature “camera” at one end and is controlled by the doctor. The “camera” is inserted and is responsible for taking pictures of intestinal lesions for doctors to diagnose. Pan Wensheng said, colonoscopy in the large intestine while walking and shooting is easy, the difficulty is how to let the lens can “wander” in the intestine will not touch the intestinal wall, this is quite a test of the doctor’s skills. “The intestinal wall is generally only 5 mm, the inflammation of the intestinal wall up to two millimeters, the fiber tube into the inside a little careless, it is easy to poke the intestinal wall, resulting in bleeding or perforation.” The reporter found that the Japanese Society of Gastrointestinal Endoscopy a statistics show that gastrointestinal endoscopy complications death cases over 70 years old accounted for half, over 60 years old accounted for 80%. The high incidence of domestic colonoscopy complications can reach 3%. The single-person method of colonoscopy can eliminate pain and suffering There are two general colonoscopy practices: the two-person method and the single-person method. “The two-person method is the doctor holds the manipulator, the nurse is responsible for inserting and delivering the mirror, this is about the coordination of two people. The single person method is a doctor’s left hand holds the manipulator, the right hand inserts the mirror, easy to manipulate.” Pan Wensheng introduced that this single person painless colonoscopy in the gastroenterology department of Zhejiang Medical Second Hospital can greatly reduce complications, only one complication in about 3,000 cases, the complication rate is equivalent to 0.03%. He did more than 1,000 in one year last year. A painless colonoscopy can be completed in an average of 10 minutes, and the patient does not need anesthesia and can clearly watch the entire colonoscopy process. The new technology is starting to be used for treatment At present, the painless colonoscopy technology is only satisfied with the examination and diagnosis of colorectal diseases and intestinal cancer, and the task of undertaking treatment has just begun. ”Under the colonoscopy can stop the bleeding in the large intestine, the patient can be exempted from the systemic hemostatic drugs, and the economic burden is reduced. In the future, it can also be used to go directly to the intestine for the removal of polyps and early colorectal cancer, and some patients can do without surgery.” Pan Wensheng said, with the development of economic and social development, people’s diet structure changes and the aging of the population, the incidence of colorectal disease gradually climb, colonoscopy will also have an important role in diagnosis and treatment. However, there are not many doctors who are skilled in painless colonoscopy techniques. Pan Wensheng studied in Japan for eight years before reaching the “wandering” realm of colonoscopy. He says doctors with long fingers are better at this technique. “The control panel is the size of the palm of your hand, and there are three knobs on it, so it’s easy for people with long fingers to coordinate.”
