The omental bursa is a large peritoneal recess located in the abdomen, posterior to the stomach and the lesser omentum. It is also known as the lesser sac, in contrast to the main and larger part of the peritoneal cavity which is referred to as the greater sac. These two cavities are connected by the epiploic foramen (of Winslow). The size of the omental bursa varies greatly, mainly due to the volume of the organs that make up its walls.
