Gallbladder stones are one of the more common benign lesions in our country. Generally speaking, patients with gallbladder stones are prone to recurrent inflammation, which seriously affects the normal life of patients. What are the specific causes of recurrent gallbladder stones? Gallbladder stones are formed due to excessive concentration of bile in the gallbladder over a long period of time, or due to abnormal lipid metabolism in the patient’s body and excessive precipitation of cholesterol crystals in the bile attached to the gallbladder. Once the gallbladder stone enters into the gallbladder duct, due to the spiral valve structure in the gallbladder duct and the thin diameter of the duct, the gallbladder stone can easily cause the stone to become embedded and cause persistent spasm of the bile duct, resulting in abdominal pain, abdominal distension, nausea and vomiting, and other clinical symptoms. If the stone is relatively loose, the stone can be loosened with the bile duct spasm, and once the stone recedes into the gallbladder on its own, the patient’s pain symptoms can gradually disappear. This is an important reason why stones may recur. In some patients with gallbladder stones, if the size of the stones is small, they can be excreted into the common bile duct, forming secondary bile duct stones, which can also cause recurrent pain, vomiting and other clinical symptoms. Some patients may even induce acute purulent obstructive cholangitis, acute severe pancreatitis and other serious complications that endanger patients’ lives. Therefore, it is recommended that once gallbladder stones are detected, timely surgical treatment can prevent serious complications.
