greater curvature
The longer, left border of the stomach along which sleeve gastrectomy resection is performed.
Full Definition
The greater curvature is the longer, convex border of the stomach that extends from the cardiac notch to the pyloric antrum along the left side of the organ. In bariatric surgery, particularly sleeve gastrectomy, the greater curvature serves as the primary resection line where the majority of the stomach is removed. The short gastric vessels and greater omentum are attached along this border, requiring careful dissection during surgery. Proper identification and mobilization of the greater curvature is crucial for achieving adequate gastric volume reduction while preserving the lesser curvature and maintaining proper gastric geometry.
Usage
Usage note: Distinguish from lesser curvature; key anatomical landmark in sleeve gastrectomy.
