胃癌是中国常见的消化道肿瘤之一，手术治疗仍然是根治胃癌的基石。基于国内、日韩和欧美的实践和循证医学证据，已经形成以根治性的胃切除、规范的淋巴结清扫和消化道重建的手术模式。在胃癌外科手术的根治性、安全性基础上，更加注重患者术后长期生活质量。同时近年来，在胃食管结合部腺癌、功能保留胃切除术及微创治疗方面有了一定进展。规范化的胃切除及淋巴结清扫，即高质量的外科手术，是提高胃癌患者预后的重要因素。针对不同分期，外科治疗只有在适当的时机给予精准、规范的治疗，才能使患者获益最大化。

Gastric cancer is a common gastrointestinal tumor in China，and surgical treatment is still the cornerstone of the radical treatment of gastric cancer. Based on the practice and high quality evidence in China，Japan，South Korea，Europe and the United States，the surgical strategy of radical gastrectomy，standardlymph node dissection and digestive tract reconstruction has been established. Based on the radical and safety of gastric cancer surgery，more attention should be paid to long-term quality of life. Recently，some progress has been made in the aspects of esophagogastric junctionadenocarcinoma，function-preserving gastrectomyand minimally invasive treatment. Standardized gastrectomy and lymph node dissection，namely，high quality surgery，are important factors to improve the prognosis of gastric cancer patients. According to different stages，only precise and standardized surgical treatment at the appropriate time can maximize the benefit to patients.
