I have encountered a few patients who have had gallbladder stones for many years and have had episodes of cholecystitis, but why don’t they have surgery? Is there any basis for this statement? It is true that a very small number of patients have stones in the bile ducts several years after gallbladder removal, but this does not mean that stones will grow in the bile ducts after gallbladder removal. Some patients have a combination of gallbladder stones and bile duct stones, while others have only bile duct stones and no gallbladder stones. Therefore, it means that even if the gallbladder is not removed, the bile ducts will grow stones. The composition of gallbladder stones and bile duct stones is different, as gallbladder stones are mostly cholesterol stones, while bile duct stones are mostly bile pigment stones. Millions of gallbladder removal cases are performed worldwide every year, and long-term clinical observations have not revealed an increase in bile duct stones after gallbladder removal.
