The invention discloses a prognosis evaluation method for biliary obstruction caused by pancreatic cancer, which comprises the following steps: acquiring sample data, screening the sample data, adopting single-factor analysis and multi-factor analysis, selecting factors influencing lifetime from the sample data by using a COX proportional risk model, and evaluating the prognosis of the biliary obstruction caused by pancreatic cancer. According to sample data and factors influencing the lifetime, a model of a column diagram for lifetime prediction is established, a prediction model system is verified and compared by adopting a correction curve, a subject working curve and a decision curve, and the model established by the method has relatively good prediction accuracy; according to the method, the lifetime of the patient with the non-resectable pancreatic cancer with the biliary obstruction prepared to receive the biliary interventional operation can be evaluated and displayed in the form of a column graph, so
