Core Tip

Core Tip: In this study, a binomial logistic regression model was established to obtain the liver operation pulmonary complication scoring system (LOPCSS). The area under the curve of the LOPCSS was 0.742. As a novel and simplified assessment system, the LOPCSS can effectively predict postoperative pulmonary complications of liver surgery through perioperative factors; therefore, it can be used to evaluate the risk of liver surgical pulmonary complications.
