Core Tip

Core Tip: Currently, the evaluation of low anterior resection syndrome (LARS) symptoms in patients is solely reliant on subjective measures, such as questionnaires. There is a lack of a standardized and objective medical assessment index. We innovatively used magnetic resonance imaging (MRI) defecography to judge and quantify the compliance of neorectum after rectal cancer surgery. We established the objective diagnosis and severity evaluation criteria for LARS MRI defecography, quantify the severity of LARS by objective clinical evaluation index, which promotes the exploration of the pathogenesis of LARS.
