AB36. Does stomach have mesentery? Learning from gastric cancer surgery

Objective: This study will first confirm the existence of mesogastrium (gastric mesentery) and then examine its architecture and suggest improvements in the surgical methods for excision of gastric cancer.

Methods: By employing video laparoscopy, a number of proximal segments of dorsal mesogastrium were found being extensively scattered around the pancreas. In this study, these segments were histologically analyzed and studied.

Results: The structure of the mesogastrium was identified intraoperatively and then confirmed both grossly and histologically after the operation.

Conclusions: This study suggests for the first time a “Table Model” to describe the relationship between the stomach and gastric mesenteries.
