Key Features/Anatomical Relations
The gastrophrenic ligament is a thin layer of peritoneal tissue and forms part of the greater omentum. The gastrophrenic ligament attaches the proximal portion of the greater curvature of the stomach (near the posterior fundus) to the diaphragm. The two layers of this ligament will separate near the attachment on the stomach, which leaves a small “bare” area on its posterior surface that lacks peritoneum.
This ligament serves as the upper left border for the lesser sac of the peritoneal cavity.
