Some patients have had gallbladder stones for many years, and during follow-up visits it is found that the gallbladder has atrophied and there is no bile in the gallbladder, only stones. At this point, the doctor will recommend that the patient have the gallbladder surgically removed. Why should the gallbladder be removed for gallbladder atrophy? First of all, the reason for gallbladder atrophy is that the gallbladder wall has lost its diastolic function and the bile from the bile ducts cannot enter the gallbladder. In the gallbladder, the stones are in direct contact with the mucous membrane of the gallbladder, and the environment around the mucous membrane of the gallbladder is quite bad, which increases the chance of cancer. Secondly, in the case of gallbladder atrophy, it is more difficult to detect the morphology of the gallbladder wall, so the early stage of gallbladder wall hyperplasia cannot be well observed. Again, the gallbladder has lost its function at this time and is of little value for preservation. In conclusion, it is recommended to remove the gallbladder in case of gallbladder atrophy. Of course, if the gallbladder atrophy is not combined with gallbladder stones, the gallbladder atrophy will be very small at this time, and in this case, surgery can be disregarded.
