食管癌淋巴结清扫数目与术后并发症的关系

目的探讨食管癌手术中淋巴结清扫枚数及组数与术后并发症的关系。方法回顾性总结2008年1月至2009年12月间四川大学华西医院收治的794例行食管癌根治性手术患者的临床病理资料．分析食管癌术后并发症的危险因素。结果全组无手术死亡病例,有84例（10．6％）患者出现术后并发症。全组共清扫11770枚淋巴结,平均每例14．8枚。多因素逻辑回归分析显示．患者性别、淋巴结转移数目、吻合部位与手术医生技能水平是食管癌术后并发症的影响因素（均P〈0．05）,而淋巴结清扫枚数及组数对于术后并发症发生率并无显著影响（均P〉0．05）。结论食管癌术后并发症的发生率与一定范围内淋巴结清扫数（小于50枚）及组数的增加无关,应尺可能广沔讹涪相含咎陌协滋田结

Association between number of lymphadenectomy and postoperative complication in surgery for esophageal carcinoma

Objective To investigate the association between the number of lymph nodes retrieval and the incidence of postoperative complications in patients with esophageal carcinoma. Method From January 2008 to December 2009, 794 patients with esophageal carcinoma underwent esophagectomy and lymphadenectomy in the Department of Thoracic Surgery at the West China Hospital of Sichuan University. The clinical data, surgeons, the extent of lymphadenectomy and its association with operative mobidity were retrospectively analyzed. Results There was no operative death. A total of 84 patients with complication（10.6%） were documented. There were 11,770 lymph nodes harvested in total with an average of 14.8. Multivariate logistic regression showed that gender, number of metastatic lymph nodes, level of anastomosis, and surgeons＇ experience were risk factors associated with postoperative complications （all P〈0.05）, while the number and group of lymph node resection were not （all P〉0.05）. Conclusion Within a rational range of lymphadenectomy （ 〈 50） following esophagectomy, the postoperative complications are significantly associated with the gender, extent of regional lymph nodes metastasis, site of anastomosis and the expertise of the surgeons, but not associated with the number and group of lymph nodes resection.
