摘要
目的评价直肠癌根治术行侧方淋巴结清扫的安全性和有效性。方法共检索出符合人选标准的对照临床研究27项，用固定效应模型和随机效应模型对直肠癌侧方淋巴结清扫组与非清扫组的安全性和有效性指标进行Meta分析。结果与非侧方淋巴结清扫组相比，侧方淋巴结清扫的手术时间延长（P=0.0005），术中出血量增加（P=0.0003），小便功能障碍发生率增加（P=0.001），术后总并发症、盆腔脓肿、吻合口瘘发生率、排便功能和性功能障碍、术后总复发率、局部复发、远处转移、5年生存率差异无统计学意义。结论直肠癌根治术行侧方淋巴结清扫在预防肿瘤复发、远处转移及提高术后生存率等有效性方面未见明显优势，却延长了手术时间，增加术中出血和小便功能障碍等并发症发生率。
Objective To evaluate the safety and efficacy of lateral node dissection in rectal cancer. Methods Data of safety and efficacy in 27 case-controlled studies comparing lateral node dissection and non-lateral node dissecion in rectal cancer were meta-analyzed using fixed effect model or random effect model. Results The increased operating time, blood loss and urinary dysfunction were more common in lateral node dissection group. The postoperative total complications, pelvic abscess, anastomotic leak, sexual dysfunction and defecation dysfunction were similar in both groups. There was no reasonably clear evidence in favor of lateral node dissection for recurrance, local recurrance, distal metastasis and 5-year survival. Conclusion Lateral node dissection can neither reduce recurrence nor improve survival in the current study, which is not recommended to be a routine procedure in rectal caner surgery.
