Dr. Hiro Nakajima, former Director-General of the World Health Organization, said, “Many people die not from disease but from ignorance , and by taking measures, you can reduce half of the deaths, don’t die from ignorance.” Health is the most valuable asset of human life, and if you lose your health, you lose everything. Health screening is the process of recognizing health risk factors. When you are healthy (most people may have risk factors affecting their health), you take the initiative to examine your entire body, learn about your health status through the examination, and get information about your health. There are often many people who, after a physical examination, see the words “occupancy” or “stones” on their physical examination report, and then start to “party” when they are recommended to go to a specialist for further treatment! This article will simply popularize the four common benign diseases of the hepatobiliary system, if the future medical examination encountered, please do not worry too much! I. Fatty liver What is fatty liver? Fatty liver is a lesion caused by excessive accumulation of fat in the liver cells for various reasons. What causes it? 1. obese fatty liver The degree of fat accumulation in the liver is proportional to the weight. 30% to 50% of obesity combined with fatty liver, heavy obesity fatty liver lesion rate up to 61% to 94%. After the weight of obese people is controlled, their fat infiltration is also reduced or disappeared. 2. Alcoholic fatty liver Long-term alcoholics liver puncture biopsy, 75% to 95% have fat infiltration. It has also been observed that the incidence of alcoholic fatty liver increases 5 to 25 times if the daily alcohol consumption exceeds 80 to 160 grams. As this disease is becoming more and more popular, many unscrupulous drug dealers hit it, selling this tea that medicine on TV and online, claiming to treat fatty liver, patients often spend a lot of money, but do not see results. In fact, the best treatment for mild simple fatty liver is to control diet, quit drinking and exercise. Second, liver cysts What is a liver cyst? A liver cyst, in layman’s terms, is a round-like cavity in the liver that contains fluid. Depending on the number, they can be classified as solitary or multiple. A liver cyst is a benign liver disease. Usually liver cysts found do not need to be treated, only if they are particularly large to the point of pressing on adjacent organs (e.g. pressing on the stomach, causing discomfort such as significant fullness after meals). And even if it is treated, it can usually be done through minimally invasive surgery, so there is nothing to worry too much about. There is only one rare case – polycystic liver, and it is important to go to a specialist for further consultation in this case. III. Hepatic hemangioma What is hepatic hemangioma? Hepatic hemangioma is a relatively common benign tumor of the liver, most commonly known as cavernous hemangioma, which is often found during ultrasound or abdominal surgery. There is no evidence that it has the possibility of malignant transformation. Polypoid lesions of gallbladder What is polypoid lesions of gallbladder? Polypoid lesions of the gallbladder. Most of them are caused by three factors: gallbladder polyps, cholesterol crystals and gallstones attached to the gallbladder wall. Surgery is usually recommended for a single polypoid lesion larger than 1 cm, if it is accompanied by gallstones and cholecystitis, or if the gallbladder polyp causes a heavy burden on the mind and interferes with normal work and life. Otherwise, surgery should not be performed immediately, but the ultrasound should be repeated every 3-6 months. Patients usually have the question: Can the gallbladder be preserved by removing gallbladder polyps? It is up to the gallbladder to decide whether it can be preserved or not. If the gallbladder has atrophied, is functioning poorly or is suspected to be cancerous, then it should not be preserved. In fact, the vast majority of people who have their gallbladder removed do not have any problems with their normal life. Trust your physician, who will weigh whether it is time to remove the gallbladder. Summary: The above four common abnormalities of the hepatobiliary system can only be scientifically recognized in order to scientifically confront them, reduce unnecessary tension and undeserved waste.
