Surgical strategies for adenocarcinoma of esophagogastric junction under the era of mini-invasive surgery

With the continuous update and improvement of minimally invasive techni-ques, laparoscopic and robotic surgeries have increased significantly for the surgical treatment of adenocarcinoma of esophagogastric junction (AEG). Due to the anatomical particularity and biolo-gical characteristics of Siewert type Ⅱ AEG, surgical approach, the range of resection, lymph node dissection and digestive tract reconstruction cannot be unified at present, which is also the contro-versy between gastrointestinal surgery and thoracic surgery. Laparoscopic minimally invasive techni-que may be more conducive to lower mediastinal lymph node dissection. Laparoscopic surgery of AEG after neoadjuvant chemotherapy is safe and feasible. Robotic surgery may be the direction of minimally invasive surgery in the future. The authors mainly investigate strategies of minimally invasive surgery for the surgical treatment of AEG, and look forward to more clinical trials on Siewert type Ⅱ AEG surgery to guide surgical treatment.
