Lesser omentum: fold of peritoneum connecting the lesser curvature of the stomach and proximal 1 in (2.5 cm) of duodenum to the visceral surface of the liver.
Hepatic Attachment
Hepatic attachment is J-shaped: vertical limb attached to the margins of the fissure for ligamentum venosum, horizontal limb attached to the margins (lips) of the porta hepatis.
Clinical
Functional significance: the lesser omentum's J-shaped hepatic attachment, along the fissure for ligamentum venosum and the porta hepatis, anchors the stomach and proximal duodenum to the liver's visceral surface.
