Abstract
The bursa sac and greater omentum were considered as the dorsal mesogastrium more than 100 years. Bursectomy and omentectomy has been used as an essential part of radical gastrectomy with extended lymphadenectomy. However, structure of the bursa sac and omentum were difficult to be consistent with the definition and deduction of the mesentery. Also, it was hard to be proved that bursectomy and omentectomy could get oncological benefit from clinical randomized control trials recent years. We proposed a model of the proximal segment of dorsal mesogastrium (PSDM) here to compared with bursa model. It was demonstrated that the PSDM was consisted by the right gastric mesentery, right gastroepiploic mesentery, left gastric mesentery, left gastroepiploic mesentery, posterior gastric mesentery, and short gastric mesentery. The complete PSDM excision have been proved efficient in decreasing bleeding during operation and preventing cancer leak from PSDM during lymphadenectomy, as well as limiting the surgical hazard and developing oncological benefit. So that, PSDM model was presented as an alternative model for surgeons to practice and prove, even more evidences are still on the way.
