Definition of LARS

International consensus definition of low anterior resection syndrome

Low anterior resection syndrome (LARS) has predominantly been defined as bowel dysfunction after rectal surgery for cancer, which is detrimental to quality of life. This definition tends not to lend itself to estimations of prevalence. Additionally, fundamental characteristics that patients may experience may also not be captured when using the validated LARS score, despite the tool having valuable clinical functionality.

A LARS international collaborative group has developed a definition with direct input from a large international patient panel, which ensures that vital aspects of the patient’s experience is included. The group concluded that including these experiences into a new tool to measure LARS will allow for more accurate severity and therefore enable more precise evaluation of treatment approaches.
