The most important quality parameters of rectal cancer surgery are oncological radicality, postoperative complications, recurrence rate and survival. Rectal dysfunction following low anterior resection occurs in up to 25-50% of patients. Despite its high frequency, however, it does not receive enough attention. Rectal dysfunction after surgery includes frequent bowel movements, urgency, incomplete evacuation, incontinence or sexual and urinary dysfunctions. The complex of symptoms is collectively referred to as the low anterior resection syndrome - LARS. In this review, we discuss the alterations in anorectal physiology after low anterior resection, the etiology and risk factors of LARS, different types of neorectal reservoir construction, and various options for prevention and treatment of LARS. Furthermore, sexual and urinary dysfunction is briefly reviewed.

直肠癌手术最重要的质量参数是肿瘤根治性、术后并发症、复发率和生存率。低位前切除术术后直肠功能障碍在高达25%至50%的患者中出现。然而，尽管其发生率很高，但并未得到足够的重视。手术后的直肠功能障碍包括排便频繁、急迫感、排便不净、失禁或性功能及排尿功能障碍。这些症状的综合表现统称为低位前切除综合征（LARS）。在本综述中，我们讨论低位前切除术后肛管直肠生理学的改变、LARS的病因和危险因素、不同类型的新直肠贮袋构建，以及LARS的各种预防和治疗选择。此外，还简要回顾了性功能和排尿功能障碍。
