Application of posterior gastric mesentery in laparoscopic gastric surgery / 中华胃肠外科杂志

ABSTRACT

The posterior gastric mesentery is one of the six mesenteries of the stomach in the membrane anatomy theory. It locates in the upper area of the pancreas, surrounds the posterior gastric vessels, and is adjacent to the short gastric mesentery by the left side, and is adjacent to the left gastric mesentery by the right side, which fixes the fundus body to the posterior abdominal wall of the upper area of pancreas. Due to its anatomical structure, in complete mesentery excision (CME)+D2 surgery, it is a surgical approach to deal with gastric mesentery in the upper area of pancreas; the second step of the "Huang's three-step method" corresponds to the posterior gastric mesentery in the theory of membrane anatomy. In the surgery of benign diseases of the stomach, laparoscopic sleeve gastrectomy (LSG) and laparoscopic Nissen fundoplication, if the short gastric vessels are difficult to be exposed and safely divided, we can dissect the posterior gastric mesentery firstly, and then hoist the fundus of the stomach in order to help dissection of the short gastric vessels. The membrane anatomy theory, as a frontier theory, provides us the new surgical perspectives and paths in gastric surgery.
