Tóm tắt

Abstract Introduction With improving survival of rectal cancer, functional outcome has become increasingly important. Following sphincter-preserving resection many patients suffer from severe bowel dysfunction with an impact on quality of life (QoL) – referred to as low anterior resection syndrome (LARS). Study objective To provide an overview of the current knowledge of LARS regarding symptomatology, occurrence, risk factors, pathophysiology, evaluation instruments and treatment options. Results LARS is characterized by urgency, frequent bowel movements, emptying difficulties and incontinence, and occurs in up to 50-75% of patients on a long-term basis. Known risk factors are low anastomosis, use of radiotherapy, direct nerve injury and straight anastomosis. The pathophysiology seems to be multifactorial, with elements of anatomical, sensory and motility dysfunction. Use of validated instruments for evaluation of LARS is essential. Currently, there is a lack of evidence for treatment of LARS. Yet, transanal irrigation and sacral nerve stimulation are promising. Conclusion LARS is a common problem following sphincter-preserving resection. All patients should be informed about the risk of LARS before surgery, and routinely be screened for LARS postoperatively. Patients with severe LARS should be offered treatment in order to improve QoL. Future focus should be on the possibilities of non-resectional treatment in order to prevent LARS.
