Adenocarcinoma of the esophagogastric junction (AEG) is one of the most aggressive and poor prognosis cancers. To date, no standard procedures have been established for the surgical treatment of Siewert type II. In this study, we proposed the approach of thoracoscopic-laparoscopic Ivor-Lewis surgery plus D2 celiac lymphadenectomy (TLILD2) and aimed to investigate the patterns of lymph node metastasis and long-term survival.From June 2015 to June 2018, 72 patients accepted TLILD2 and enrolled in this study. Relevant patient characteristics and postoperative variables were collected and evaluated. The disease-free survival (DFS) and disease-specific survival (DSS) were determined by the Kaplan-Meier method and compared by log-rank tests.There was no case of postoperative death in this study, and the most common complication was anastomotic mediastinal fistula (5/72, 6.9%). A total of 2811 lymph nodes were retrieved, and the positivity rate was 11.9% (334/2811). The positivity rate of celiac and mediastinal lymph nodes was 14.4% (314/2186) and 3.2% (20/625), respectively. The percentage of patients who had positive celiac and mediastinal lymph nodes reached up to 58.3% (42/72) and 8.3% (6/72), respectively. The DFS and DSS of these 72 patients were 94% and 93.4% at 1 year after surgery and 59.8% and 62% at 3 years after surgery, respectively. The pTNM stage showed a significant difference between DFS and DSS.TLILD2 could be a potential way to promote long-term survival of AEG patients. On the basis of the patterns of lymph nodes metastasis, we suggest that lower mediastinal and D2 celiac lymphadenectomy is necessary to improve the oncological outcome.
