Patients who have undergone cholecystectomy need to pay attention to the following matters: 1. In the course of normal life, it is necessary to avoid eating large amounts of egg yolk, animal offal, animal fat, seafood squid and other foods. After eating high cholesterol food, it may increase the chance of bile duct stones. 2. After minimally invasive surgery, patients should consider drinking water on the first day after surgery. After the water test is normal, you can consider transitioning to a full-liquid diet or a semi-liquid diet. 3. Patients who have undergone gallbladder surgery should pay attention to timely review, and if they have stones, they should consider taking ursodeoxycholic acid capsules and tauro-ursodeoxycholic acid capsules in appropriate amounts for active preventive treatment.
