Upon re-entering the abdomen at necropsy, ~1L of clear-brown ascites was encountered. Two adjacent perforations were found in the fundus of the stomach (yellow arrows), and copious amounts of gastric contents had spilled into the peritoneal cavity. The stomach was still distended with feed, however. The stomach and pylorus were opened with a longitudinal incision. The pylorus was patent and the segment of duodenum where the anastomosis was located was identified. The suture line of the anastomosis was intact, patent, and without inflammation or reaction. Distal to that was a hemorrhagic segment of bowel with a mass effect (B), adjacent to the site of location of the pancreatic injection. This section of bowel was not patent (i.e., it was the site of the obstruction which produced the gastric distention which led to the perforations. The rest of the pancreatic parenchyma felt firm and was hemorrhagic. The subject had lab testing 24 h prior to expiration: WBC = 17K; Hb = 13.7; . :. . Germ layers, formed during gastrulation, are present by two weeks and include endoderm, mesoderm and ectoderm, the germ tissues are the basis of all tissues and organs. .  Endoderm -Epithelial lining and glands.
