Patient: yellowing all over the body, including the eyes. Now Harbin Medical University received intravenous treatment, but the yellow did not subside. My mental state and appetite are fine. Do I have to use a stent to draw out the yellow before I can have surgery for bile duct cancer? Laboratory and examination results: Bile duct cancer. Doctor: Not necessarily. If there is no combined biliary tract infection and no contraindication to surgery, surgery is possible.
