The left renal vein lymph node (LRVLN) may be the extended locoregional node in esophagogastric junction cancer; however, only open-surgical methods of dissection have been reported. We therefore developed a novel minimally invasive laparoscopic method for LRVLN dissection. Following esophagectomy, the stomach was mobilized and LRVLN dissection was started by taping the pancreatic body using two silicone drains. The transverse mesocolon was then retracted through the superior duodenal fossa to expose the horizontal duodenum and permit LRVLN dissection. We carried out the procedure successfully in 17 patients with advanced esophagogastric cancer. The median total and laparoscopic operative times were 415 and 161 min, respectively. Postoperative esophagectomy-related complications occurred in six patients. The median estimated blood loss was 120 ml and hospital stay was 15 days. This minimally invasive laparoscopic LRVLN dissection method was safe and effective, and may support faster recovery and earlier postoperative adjuvant therapy in patients with esophagogastric junction cancer.
