A 2.3mm stone in the cystic duct usually does not cause symptoms and can be observed dynamically, but if the stone is found to be enlarged or painful during observation, then laparoscopic cholecystectomy should be performed in time. The stones are usually produced in the gallbladder, after which smaller stones fall into the cystic duct and stay there for a long time, and some patients with cystic duct stones may not show any symptoms. However, patients with more serious stones in the cystic duct often experience recurrent abdominal pain, which is caused by the bile in the gallbladder not being able to pass from the cystic duct to the common bile duct, which increases the pressure inside the gallbladder and causes pain in the right upper abdomen. However, stones with a size of 2.3mm may not cause the above mentioned symptoms, and generally do not require special treatment. However, as the patient grows older, the stone may gradually increase in size, and when it is large enough, it may cause complete obstruction of the cystic duct and cause strong abdominal pain. Therefore, it is enough to do dynamic observation of the smaller stones, and once prolonged abdominal pain occurs, laparoscopic cholecystectomy should be considered as soon as possible after diagnosis is confirmed by CT.
