淋巴结转移是影响胃癌病人预后的一项独立因素，合理、规范的淋巴结清扫是胃癌根治术的关键。胃癌根治术后并发症发生率与淋巴结清扫范围有关。经验欠丰富的术者施行D2根治术或更广泛的淋巴结清扫时更容易导致术后严重并发症的发生。加强胃癌根治术规范化培训，推广规范化外科治疗的理念和技术是减少淋巴结清扫相关并发症的重要保证。

Abstract    Lymph node metastasis is an independent prognostic factor in patients with gastric cancer, the reasonable lymph node dissection is critical to radical gastrectomy. Extended nodal dissection is the most important surgical factor related to postoperative risk of complications. For the surgeon with limited experience of lymphadenectomy, D2 or more extensive lymph node dissection is more likely to cause the occurrence of  severe postoperative complications. The rigorous training for surgeons and promotion of a standardized treatment concept, can effectively reduce lymphadenectomy-related complications.
