Stomach, Asian

Description

Centered in the upper abdomen, the stomach lies inferior to the diaphragm and left lobe of the liver, receiving the terminal esophagus at the cardia just left of the midline. The lesser curvature runs along the superomedial border toward the pylorus on the right, while the greater curvature arcs inferolaterally toward the fundus and body. Along the lesser curvature, the lesser omentum is shown spanning to the undersurface of the liver, forming the hepatogastric ligament and continuing toward the pyloric region. Proximal and distal segments of the esophagus and gastric outlet are emphasized within a translucent anterior torso view. Clinically, this orientation is the one you need when teaching the gastroesophageal junction and the transition from thoracic to abdominal esophagus, a common site for reflux-related mucosal injury and Barrett esophagus. The lesser omentum matters for operative anatomy because the hepatogastric ligament is opened to access the lesser sac, and the hepatoduodenal ligament at its right margin contains the portal triad, a landmark in cholecystectomy and in control of upper gastrointestinal bleeding. Short and practical. Use this illustration in gross anatomy and GI block teaching to anchor surface anatomy of the epigastrium and left upper quadrant, or in patient education materials explaining endoscopy, hiatal hernia, and peptic ulcer disease near the pylorus and lesser curvature. It also suits surgical overviews introducing antrectomy, pyloroplasty, or approaches to the lesser sac in upper abdominal procedures. Anatomical accuracy verified by SciePro's Medical Advisory Board.
