What is good to eat after choledochotomy is generally based on the type of surgery, as well as the recovery of different factors to make an objective analysis. If open surgery of the common bile duct is performed, before the gastrointestinal function is fully recovered, only warm water, rice soup and noodle soup can be eaten to avoid eating more food and causing abdominal pain and bloating. Second, if endoscopic retrograde cholangiopancreatography is used to treat common bile duct disease, due to the small trauma of the operation, there is no incision in the abdomen, no food can be eaten within 72 hours after the operation, and if there is no obvious abdominal pain and bloating symptoms after 72 hours, food such as thin porridge, noodles and steamed eggs can be eaten, which is conducive to faster recovery.
