Dissection of stomach
Blood vessels and nerves of lesser curvature of stomach, close-up view
The omental bursa, that portion of the peritoneal cavity which lies posterior to the lesser omentum and stomach, has been opened by dissection of the lesser omentum. In the drawing, an arrow indicates the position of the epiploic foramen behind the hepatoduodenal ligament and suggests the continuity of the general peritoneal cavity with the omental bursa. The point of the arrow lies in the vestibule of the bursa from where the superior recess extends behind the caudate lobe of the liver. The bursa continues to the left across the body of the pancreas (21) toward the spleen but this part is obscured by the overlying stomach.
