Low anterior resection syndrome (LARS) is a highly prevalent condition that can develop after anal sphincter-sparing surgery for rectal cancer and impair patient quality of life (QOL). In addition, since there is a correlation between the severity of LARS and QOL, active intervention for LARS is indispensable for improving QOL. LARS and anal dysfunction have become well-known conditions that must be dealt with in daily clinical care. Even if rectal cancer is completely cured, LARS continues semi-permanently, remaining a major problem for patients. Therefore, surgeons need to view it as a serious postoperative complication. By presenting the findings and future prospects regarding LARS and anal dysfunction including intersphincteric resection for lower rectal cancer, it is hoped that the QOL of patients who have undergone radical rectal cancer surgery will improve.
