Abstract Although biliary tract Chinese Society of Nutritional Oncology malignancy is not common in the world, its
incidence is increasing year by year and its malignancy is high. The incidence of biliary tract malignancy in China is also
increasing year by year. The prognosis of patients with cholangiocarcinoma is poor. Therefore, the palliative and supportive
treatments of malignant tumors of the biliary tract system are particularly important, with the main purpose of improving the
quality of life and extending the survival time as much as possible. The malignant tumor palliative biliary system and nutrition
treatment is particularly important. Its main purpose is to improve the quality of life as much as possible, to prolong survival
time. Early postoperative feeding in patients with hilar cholangiocarcinoma can effectively reduce the incidence of complications
such as abdominal distention and urinary retention, and accelerate postoperative rehabilitation of patients. The principle of
selection of nutritional treatment approaches for biliary tract malignant tumors is basically the same as that for other malignant
tumors, but it also has its characteristics:1. biliary tract surgery is mostly limited to the upper digestive tract, and the intestinal
canal below the jejunum is less affected. 2. For patients with preoperative malnutrition, especially those with moderate or above
obstructive jaundice, enteral nutrition through oral or nasojejunal catheterization or through T⁃tube jejunal catheterization is
recommended. For patients with poor liver function reserve and extensive hepatectomy or severe obstructive jaundice, biliary
stent drainage or percutaneous hepatocentesis biliary drainage should be actively performed for biliary decompression, so as to
improve liver function as soon as possible and promote the metabolism and absorption of nutrients. 4.PTCD is a method widely
used in clinical treatment of malignant biliary obstruction
