摘要
目的 探讨直肠癌根治术中各临床病理特征、手术时间等相关因素对肠腔内肿瘤细胞脱落的影响。方法对我科2007年7月至2009年7月期间诊断为直肠癌并行根治手术的68倒患者行前瞻性研究，术中在离断肿瘤下端肠管前行肠腔内灌洗，收集灌洗液送病理科．送检标本中的癌细胞。统计检测结果。结果送检标本中，阳性标本共有30例，阴性标本38例。对可能影响检出结果的各因素行单因素统计分析，结果患者的年龄、肿瘤大小、TNM分期、手术时间差异有统计学意义（P〈0．05）。结论直肠癌根治术中必须常规行肠腔内灌洗，特别是肿瘤TNM分期晚、瘤体大及手术时间长的病例，更需重视肿瘤细胞脱落导致术后局部复发的风险。
Objective To analyze the risk factors inducing tumor cells extoliating during radical resection ot rectal cancer. Methods Sixty-elght patients who were diagnosed as rectal cancer from July 2007 to July 2009 and given radical operations were assigned prospectively in this study. Before cutting the rectal stump below the tumor,saline was instilled into rectum to irrigate the stump. Collected irrigating fluids were sent to pathology laboratory.The results of examines were collected and statistical analysis. Results Exfoliated malignant cells were found in 30 samples. By univariate analysis,the statistically significant factors defining a high risk of exfoliating were age, tumor size,TNM stage,operation time （P〈0.05）. Conclusion Irrigating the rectal stump before cutting down the tumor is essential to avoid local recurrence.
