The lymphatic system of the pancreas is a complex, intricate network of lymphatic vessels and nodes responsible for the drainage of the head, neck, body, and tail of the pancreas. EBioMedicine. Both exocrine and endocrine secretions of the pancreas may enter thoracic duct lymph directly in pancreatic lymph, but in normal circumstances this route of entry is not quantitatively important. Microsc Res Tech. It should be noted that the upper abdomen lymphatic channels generally follow the arterial supply and this holds true with the pancreas. Arches of venules connect with a larger vein that runs the length of the body of the pancreas. In consequence, they become inadequate at an even earlier stage in subsequent attacks of inflammation and thereby predispose to chronic and recurrent pancreatitis. In this sense, the lymphatics may be considered to serve as an overflow, protective, or safety system. Lymph is drained from the body and tail of the pancreas via lymphatic vessels that empty into the pancreaticosplenic lymph nodes located along the splenic artery. et al. Acute pancreatitis was induced in anaesthetised dogs in order to investigate the relative contribution of peritoneal ascitic fluid and thoracic duct lymph as However in random areas, both intra- and interlobular lymphatics come into close relationship with acinar cells. The structural relationships between lymphatics and pancreatic parenchymal cells also make clear that lymph is not a significant pathway for their secretory products. 2016 Oct 20;13(5):475-484. doi: 10.1007/s13770-016-0014-1.
