Management and rehabilitation based on symptom classification in low anterior resection syndrome: current perspectives

Low anterior resection syndrome (LARS) represents the most frequent complication following sphincter-preserving radical surgery for rectal cancer, substantially compromising patients' postoperative quality of life. While historically considered a transient adverse outcome, LARS is now recognized to exert prolonged physiological and psychological impacts. Currently, standardized clinical strategies for its diagnosis and management remain lacking, posing a major challenge to improving overall rectal cancer care. Recent data suggest that symptom-based classification and tailored rehabilitation have emerged as predominant approaches in LARS management. This review aims to provide a commentary on this evolving paradigm.
