Predictive factors of low anterior resection syndrome following anterior resection of the rectum.

Objective: to identify predictors of low anterior resection syndrome (LARS) that can contribute to its early diagnosis and treatment.

Methods: we conducted a retrospective cohort study of patients undergoing anterior resection of the rectum between 2007 and 2017 in the Coloproctology Service of the Federal University of Parana Clinics Hospital. We performed Receiver Operating Characteristic Curve (ROC) analysis to identify LARS predictive factors.
