				        	The unique multi perspective and magni-fying effect of laparoscopic surgery make gastric surgery more precise and minimally invasive. The technical innovation of 4K laparoscopy enable surgeons to understand the finer submicrostructure-membrane anatomy. The advantages of perigastric lymph node dissection with less trauma and bleeding under the guidance of membrane anatomy theory are widely recognized. As a common metastatic site of advanced distal gastric cancer, lymph nodes in the infrapyloric region play an important role in radical gastrectomy. Blood vessels variation is common in the inferior pyloric region, and the layer between gastric and mesenteric membrane is complex. Complete resection of the right gastric omentum membrane can yield greater surgical benefits. In this article, the author discuss the key points of lymph node dissection in the subpyloric region based on their surgical experience, aiming to promote the standard surgical procedure of 4K laparoscopic lymph node dissection in the inferior pyloric region based on membrane anatomy.
