In clinical work, we often encounter some misconceptions about gallbladder stones: 1, the smaller the stones, the less severe the disease, the larger the stones, the more severe the disease. Some very small stones, sometimes called sediment-like stones, usually about 5mm in diameter, are easily discharged from the cystic duct into the common bile duct, and often get stuck in the outlet of the common bile duct, leading to cholangitis and pancreatitis. Some stones with a diameter of about 1 or 0 cm can easily get stuck in the neck of the gallbladder, causing cholecystitis and even gallbladder necrosis and perforation. 2. Stones need to be ignored as long as there are no symptoms. Gallbladder stones can be found without pain and other symptoms during physical examination, etc., but they are not always maintained, and some patients can develop pain and other symptoms after several years. In addition, some filled stones or stones with a diameter greater than 3 or 0 cm can cause gallbladder malignancy. 3, gallbladder removal affects digestive function. The gallbladder itself does not secrete bile, but mainly concentrates and stores bile, and the liver secretes bile. After the gallbladder lesion, it not only loses its function, but also affects eating (aversion to greasy food, inducing pain, etc.). 4. Gallbladder stones will grow again in other parts after removal. There are millions of gallbladder removal patients worldwide every year, and there is no evidence to support this claim. Some patients with gallbladder stones are themselves combined with bile duct stones.
