Ms. Huang, a Guangdong reader, asked: Some people in my family have stomach cancer, so they want their parents to do regular gastrointestinal endoscopy to prevent cancer. But they are afraid of doing gastroscopy. I heard that there is a capsule endoscope that is less painful. May I ask for screening? How effective is the traditional gastroenteroscope?
Liu Side, director of the Department of Gastroenterology, Nanfang Hospital, Southern Medical University, answered: Gastrointestinal tumors can be controlled, but doctors can't achieve the desired results. They also need residents to increase their awareness of early diagnosis and actively carry out early screening for cancer. As long as timely screening, Reliance on existing medical technology has been able to find very early cancer and even precancerous lesions. If it can be detected early in the digestive tract tumors, the cure rate can reach more than 95%. Age is the first risk factor for digestive tract tumors. Aged and above, esophageal cancer, colorectal cancer above 45 years old, the incidence rate will rise straight. The age-appropriate population should pay attention to the risk of esophageal, stomach cancer, 40-year-old must do a gastroscopy screening, 45-year-old must do a colonoscopy screening , If found atrophic gastritis, polyps, hyperplasia and other cancerous lesions, should be treated as soon as possible.
Gastroenteroscopy is an invasive test. There is no pain in the capsule endoscope. After swallowing the capsule endoscope, the lens starts taking pictures from the esophagus until it is naturally discharged. Each time about 50,000 photos are taken. Nowadays it is possible to use robots. Strength, examines tens of thousands of pictures one by one, pinpoints to the lesion accurately, assists the doctor to complete 70% of readings. The robot can grasp the picture's texture, outline, color feature in the process of observing the picture. Out of it, the accuracy is greatly improved.
