A scoping review of risk prediction models for low anterior resection syndrome in patients undergoing sphincter-preserving surgery for rectal cancer

Low anterior resection syndrome (LARS) is a common complication in patients with rectal cancer following low anterior resection. With the continuous maturation and clinical popularization of sphincter-preserving surgical techniques, the clinical incidence of LARS has shown an upward trend, with an overall incidence of 70%–90%.In recent years, LARS has become a key factor restricting the improvement of quality of life in patients with rectal cancer after surgery.At present, various risk prediction tools for LARS after sphincter-preserving surgery for rectal cancer have been developed, but their applicability and accuracy vary, and no widely recommended authoritative tool is available.It is necessary to evaluate these risk prediction models and find the truly capable and effective ones, providing a beneficial prediction model for the risk of LARS in such patients.
