Abstract:
The most common metastasis modality of gastric cancer is the perigastric lymph node metastasis. Complete dissection of regional lymph nodes of the stomach is the core surgical treatment strategy of gastric cancer, and is closely related to the prognosis of gastric cancer patients. Infrapyloric lymph node metastasis is common in gastric cancer,and its incomplete dissection is associated with tumor recurrence. Meanwhile, anatomical variations of vessels and complex mesentery layers of infrapyloric area increase the difficulty of lymphadenectomy during the operation. So, infrapyloric lymph node (No. 6) is an important station. Based on the theory of embryonic development and complete mesogastrium excision, operation across the anatomical space among mesentery layers can ensure en bloc resection of the infrapyloric lymph nodes.
