Pancreatic head cancer is one of the more malignant types of digestive system tumors, and if only conservative treatment is taken, the survival period of patients is usually about six months to one year. Conservative palliative treatment for pancreatic head cancer includes biliary-intestinal anastomosis and gastrojejunostomy to relieve biliary obstruction or duodenal obstruction, which are usually applied to patients of advanced age or those who have liver metastasis and combined with significant cardiopulmonary dysfunction and cannot tolerate surgery. These patients usually have serious underlying diseases and most of them have weak body functions. In addition, pancreatic head cancer is very prone to distant metastasis in advanced stages, so patients with pancreatic head cancer treated conservatively usually do not have a long survival period, which may be less than one year. Patients with conservative treatment of pancreatic head cancer should maintain a positive and optimistic attitude and cooperate with the treatment methods of doctors, so as to prolong the survival time and improve the quality of life.
