Low anterior resection is one of the most widespread approaches to treat rectal cancer.
Sphincter-sparing procedures are currently feasible in up to 80 percent of patients requiring surgery for rectal cancer. Between 25 and 80 % of patients who undergo this kind of procedure develop one or more symptoms of low anterior resection syndrome (LARS).
There is currently no clear consensus about LARS definition, but some risk factors are clearly identified.
The LARS score is the most widespread tool to assess the severity of LARS.
A multidisciplinary approach is the best treatment for LARS.
