Mesenteric-guided approach to pyloric lymphadenectomy in laparoscopic radical gastrectomy

Figure 1 Schematic illustrations of the right gastroepiploic mesentery: Anatomical components, separation, and dissection. A: Schematic diagram of the three key anatomical components of the right gastroepiploic mesentery; B: Schematic diagram showing the complete separation of the right gastroepiploic mesentery from the transverse mesocolon and identification of the three suspension points of the right gastroepiploic mesentery “anterior” surface; C: Schematic diagram showing the exposure and division of the connection of the right gastroepiploic mesentery; D: Schematic diagram showing the exposure and division of the right gastroepiploic mesentery “posterior” surface. ASPDV: Anterior superior pancreaticoduodenal vein; GDA: Gastroduodenal artery; RGEV: Right gastroepiploic vein; RGEA: Right gastroepiploic arteria; CME: Complete mesogastric excision; CVL: Central vascular ligation; A: Anterior; P: Posterior; A1: First suspended point; A2: Second suspended point; A3: Third suspended point.
