Acute Edema of the Pancreas, Gallbladder and Stomach in Serum Anaphylaxis

Abstract

As far as we are aware, the occurrence of acute edema of the gallbladder, pancreas and stomach has not been described as a consequence of serum anaphylaxis in the dog.Incidence. In 21 dogs, we observed edema of the pancreas 8 times; edema of the gallbladder-mucosa and adventitia 15 times; and edema of the stomach-submucosa 8 times.Degree of Edema. This varied considerably; in the pancreas the entire gland could be involved so that the lobules were separated by a clear, watery fluid; or the edema was largely limited to that portion closely adherent to the duodenum and antrum.The lymph glands between the pancreas and stomach were generally black, hard and gorged with blood. Other lymph glands of the viscera appeared normal.In the gallbladder the edema of the mucosa and adventitia varied between 1 and 3 mm in thickness; the fundus was chiefly involved and the edema was less on the body and apparently absent on the neck of the bladder.In the stomach, the edema was found chiefly in the submucosa of the antrum ...
