Gallstones found during physical examination, how to deal with asymptomatic gallstones, “quite a lot of asymptomatic gallbladder stones” or those with mild symptoms or young and middle-aged patients, these people often have normal gallbladder function, and it is especially important to preserve the gallbladder. At present, due to the maturity and development of biliary endoscopy technology, minimally invasive endoscopic techniques can be used to remove stones and preserve the gallbladder with less pain, less trauma and shorter hospital stay (3-4 days after surgery). More importantly, it preserves the functioning gallbladder and avoids a series of complications after gallbladder removal. The conditions needed for gallbladder removal are generally difficult to achieve: normal gallbladder size and shape, gallbladder wall thickness less than 0.5 cm; the size, number and nature of stones are not necessary to preserve the gallbladder, that is, the size and number of stones do not affect the preservation of the gallbladder. If the above conditions are not met, the gallbladder is bound to be removed as well. Our general misconception is that surgery or medication can cure the disease once and for all, in fact, it is wrong, many times make us unhealthy life and diet, we must pay attention to diet regulation, even after surgery and medication, but also to change their eating habits, otherwise many diseases will still recur, such as gallstones after surgery can be maintained for a period of time, if not pay attention to the easy recurrence of bile duct stones.
