Resection of the automonic nervous system in the process of lymph nodes dissection is a major factor leading to postoperative gastrointestinal dysfunction.The era of blind expansion of the wide excision has been questioned,and safety first,radical dissection of the metastatic lymph nodes,low invasive rate and organ function-saving surgery have been highly emphasized.Preserving the gastric autonomic nerve effectively reduces postoperative diarrhea,shortens the time for weight recovery,and prevents insulin secretion disorders and postoperative cholelithiasis.In the process of laparoscopic or open autonomic nerve preservation in lymph node dissection for gastric cancer,full understanding of the anatomy of the autonomic nervous system,recognizing the landmark of the nerves,proper designing the surgical space,dissecting according to the extracellular space in the membrane of the nerve fibers and nerve plexus are factors which ensures the quality and effects of the surgery.
