After stent surgery for cholangiocarcinoma, diet should be light and nutritious, and more high-fiber, high-vitamin and high-protein foods can be consumed. 1. High fiber: for example, corn, wheat, buckwheat, sorghum, oats, etc. These foods are rich in fiber, which is an important element needed by human body. 2. High vitamin: for example, banana, kiwi, apple, cucumber, strawberry, etc., which mainly contain vitamin C, vitamin B and also vitamin D, which can replenish the important components needed by human body and are more suitable for cholangiocarcinoma patients to consume after surgery. 3. High protein: for example, lean pork, fish, shrimp, crab, scallop, etc. These foods are rich in protein and also contain calcium needed by human body, which are more suitable for patients who are weak and sick. After installing stent, bile duct cancer patients should try to eat mainly fluids or semi-fluids at the initial stage, and then adjust the amount of diet appropriately according to the individual’s digestive condition afterwards. If there is any discomfort after the operation, please consult the doctor in time to avoid delaying the condition.
