摘　　要：目的检验直肠癌低位前切除综合征（low anterior resection syndrome,LARS）评分表中文版用于评估患者排便失调严重程度的信效度。方法便利选取2012年12月至2014年2月在重庆市某三级甲等医院行直肠癌低位前切除术后的患者108例,应用中文版LARS评分表评估其术后排便失调程度,并询问其肠道症状对生活质量的影响程度以检验聚合效度;随机抽取50例患者在首次评估后1~3周进行第2次测试,以检验重测信度;结合患者一般资料检验LARS评分表对不同临床特征人群的判别效度。结果中文版LARS评分表具有良好的重测信度,首次测量与再次测量之间差异无统计学意义（P=0.97）;该量表评分值与生活质量紧密相关,聚合效度良好（P〈0.001）;敏感度为93.8%,特异度为76.7%;量表的判别效度良好,能区分不同性别、年龄、吻合口平面的人群（P〈0.05）。结论中文版LARS评分表具有良好的信效度,用于评估直肠癌低位前切除术后患者排便失调的严重程度高效、可信。Objective To test the reliability and validity of Chinese version of low anterior resection syndrome score in evaluating the defecation disorder.Methods By convenience sampling,108 patients who underwent low anterior resection were selected and investigated their defecation disorder by using LARS and asked the impact of bowel function on quality of life to test the convergent validity.A subgroup of 50 patients completed the LARS score twice to test reliability.Also combine the patient＇s general information to test the reliability of LARS in different clinic syndrome.Results The Chinese version of scale demonstrated high reliability at test-retest with no statistically significant difference between scores at the first and second test（P=0.97）.It demonstrated a high convergent validity in terms of a high correlation between LARS score and quality of life（P〈0.001）.Sensitivity was 93.8% and specificity was 76.7%.The Chinese scale was able to differentiate patients regarding to gender,age and anastomotic level（P〈0.05）.Conclusion The Chinese version of the LARS score has proven to be a valid and reliable tool for measuring rectal cancer patients with defecation disorder.
