Low anterior resection syndrome (LARS) is increasingly recognized as a concern after low anterior resection for the treatment of rectal cancer. The lack of a precise definition outlining the symptoms and the time course that constitute LARS hinders ongoing research into the incidence, risk factors, pathophysiology, and treatment of this syndrome. This review will outline the current characterization of LARS, the approach to measuring LARS, and the risk factors for development of LARS. It will highlight the significant heterogeneity in the literature to date and the limitations in our understanding of LARS.
