Patients with advanced pancreatic head cancer usually have shorter survival time, mostly 0.5 to 1 year, and the 5-year survival rate is usually less than 1%. Doing bile duct drainage for patients with advanced pancreatic head cancer can reduce jaundice and improve patients’ quality of life, but it doesn’t have much effect on prolonging survival time. Pancreatic head cancer is a kind of malignant tumor in digestive tract, which develops rapidly and is easy to metastasize. Most of the early patients do not have obvious symptoms, so when they are found, they are usually in middle or late stage, with unsatisfactory treatment effect, poor prognosis and extremely low survival rate of about half a year to one year. Bile duct drainage can reduce jaundice and improve patients’ quality of life, and it does not significantly help to prolong patients’ survival time. If diagnosed with advanced pancreatic head cancer, it is recommended to carry out active treatment under doctor’s guidance to relieve pain, dyspepsia, jaundice and other symptoms, so as to improve patient’s survival quality.
