Abstract

The greater omentum is a large peritoneal fold that hangs down from the greater curvature of stomach like an apron. It consists of a double sheet of peritoneum folded on itself; hence, it is made up of four layers. The anterior two layers come down from the greater curvature of the stomach and the first part of the duodenum. They pass in front of the small bowel, sometimes as low down as the pelvis. They then ascend again to the transverse colon. They encompass a variety of structures, small intestines, transverse colon, and spleen [1].
