Lateral Expanse of the Greater Curvature of the Stomach

Description

Sweeping along the lateral profile of the stomach, the greater curvature forms a long convex border from the cardiac region near the gastroesophageal junction down toward the pyloric part. Superiorly it relates to the fundus, while inferiorly the body of the stomach descends before turning medially toward the pylorus, leaving the greater curvature as the most lateral and inferior gastric margin in this perspective. A peritoneal reflection is implied along this border where the greater omentum takes origin, with the anterior and posterior layers of peritoneum draping inferiorly like an apron. Surgeons and endoscopists track the greater curvature as a consistent landmark when orienting the stomach in a rotated abdomen, and its peritoneal attachments explain how disease can spread beyond the stomach. Gastric ulcers and carcinomas along the greater curvature can invade the gastrocolic ligament and transverse colon, and lymphatic drainage tends to course toward the right and left gastro-omental (gastroepiploic) vessels within the greater omentum. It also frames key operative planes: division of the gastrocolic ligament to enter the lesser sac during distal gastrectomy or pancreatic exposure typically starts along this border. Editors will find this view fits cleanly into upper gastrointestinal anatomy chapters, teaching the distinction between greater and lesser curvatures and introducing the greater omentum as a peritoneal fold with surgical consequences. It also supports bariatric surgery and general surgery teaching materials that discuss sleeve gastrectomy, where stapling runs parallel to the lesser curvature while mobilization requires freeing the greater curvature from the gastro-omental attachments.
