FIG. 132. Dissection of the Abdomen to display the Posterior Wall of 

 the Omental Bursa and some of its relations ; a stage further of the 

 dissection shown in Fig. 131. 



The greater part of the left lobe of the liver has been removed and the 

 remainder of the liver has been displaced upwards and to the right. The 

 round ligament of the liver and the falciform ligament have been stitched 

 to the right costal arch. All the lesser omentum, except the posterior 

 layer of its right free margin, has been removed or turned aside. 



The greater omentum has been detached from the lower part of the 

 greater curvature of the stomach and a large segment of the wall formed by 

 its anterior two layers has been removed. 



The stomach has been divided near its pyloric end and afterwards 

 turned upwards and to the left under cover of the left costal arch, to the 

 margin of which the divided end has been fastened. 



A portion of the peritoneal layer which forms the upper part of the 

 posterior wall of the omental bursa has been removed .to display a part of 

 the pancreas. 



The posterior wall of the omental bursa, which is displayed, is formed 

 from below upwards by ( I ) the posterior two layers of the greater omentum. 

 (2) The transverse colon, enclosed between two layers of peritoneum which 

 are continuous below with the posterior two layers of the greater omentum 

 and above with the two layers of the transverse meso-colon. (3) The 

 transverse meso-colon, formed by two layers of peritoneum of which only 

 the upper or anterior is visible in the figure. (4) The ascending layer of 

 the transverse meso-colon, which is the upward prolongation of the upper 

 layer of the transverse meso-colon across the anterior surface of the pancreas 

 to the diaphragm.
