Abstract    Adenocarcinoma of esophagogastric junction(adenocarcinoma of esophagogastric junction, AEG) is a special type of tumor with a special location, different from gastric cancer and esophageal cancer, and with unique biological behavior. Lymph node metastasis is one of the most common metastatic routes of AEG, and lymphatic metastasis can occur to the lower mediastinal lymph nodes on the oral side and the abdominal lymph nodes on the anal side. Therefore，in addition to the routine dissection of abdominal lymph nodes, the lower mediastinal lymph nodes should be included in the scope of the dissection for patients with AEG undergoing radical surgery. However, there is still a lack of high-level evidence to support the applicability of lower mediastinal lymph node dissection, the scope of dissection, and the surgical approach, and therefore there is still controversy, coupled with the fact that the lower mediastinal lymph nodes are located at a high level, which makes dissection difficult and is usually performed only in some experienced centers.

Key words: adenocarcinoma of esophagogastric junction, lower mediastinal lymph node, lymphadenectomy, surgical technique, laparoscopy
