Gastrolienal ligament

The spleen is almost entirely surrounded by peritoneum, which is firmly adherent to its capsule. It is held in position by two folds of this membrane. One, the gastrolienal ligament (or gastrosplenic ligament), is also formed of two layers, derived from the general cavity and the omental respectively, where they meet between the spleen and stomach); the short gastric and left gastroepiploic branches of the lienal artery run between its two layers.
