【摘要】 SiewertⅡ型和Ⅲ型食管胃结合部腺癌(adenocarcinoma of the esophagogastric junction, AEG)发病率逐年上升，外科治疗是其多学科综合治疗中最主要的治疗方式。由于其解剖学部位的特殊性，在手术方式上行食管下段切除加近端胃切除术或全胃切除术，目前一直存在较大争议。因此，本文通过分析SiewertⅡ型和Ⅲ型的AEG患者幽门部淋巴结转移情况与肿瘤部位和肿瘤大小等关系，进一步分析行近端胃切除术和全胃切除术的术后生存率、短期并发症、长期并发症是否存在差异，从而为临床上手术方式的选择提供理论依据。更多还原

【Abstract】 The incidence of Siewert type Ⅱ and type Ⅲ adenocarcinoma of the esophagogastric junction(AEG) is increasing year by year, surgical treatment is the most important method in its multidisciplinary comprehensive treatment. Because of its special anatomical location, the surgical method of lower esophagectomy plus proximal gastrectomy or total gastrectomy has been controversial at present. Therefore, by analyzing the relationship between pyloric lymph node metastasis and tumor location and tumor size in patients with AEG of Siewert type Ⅱ and Ⅲ, we further analyzed the differences in survival rate, short-term complications and long-term complications between proximal gastrectomy and total gastrectomy. It provides a theoretical basis for the selection of surgical methods in clinical practice.更多还原
