Construction and Validation of Risk Prediction Model for Gastrointestinal Dysfunction of Patient With Colorectal Cancer

To understand the current situation of the postoperative gastrointestinal dysfunction in patients with colorectal cancer effect a radical cure, and analyze the risk factors, and build the colorectal cancer radical surgery in patients with gastrointestinal dysfunction risk prediction nomogram model decision tree classification and regression tree model, through internal validation evaluation the performance of the two models in the modeling data set and dividing the postoperative gastrointestinal dysfunction risk level.Two risk prediction models were used to carry out external verification, evaluate the clinical practicability and effectiveness of the model, and provide reference for further promotion of the model.
