This manuscript proposes a synthesis of the etiopathogenic, diagnostic and therapeutic data in chronic pancreatitis based on actual information correlated with the results of our experimental study. The experiment was conducted on 18 animals, in which was performed the intraduodenal ligation of the pancreatic duct apertures and the obstruction of the pancreatic ducts with intraparenchymatous, intraoperative neoprene injections. We investigated the lesions by using intraoperative pancreatic tissue collected after injections. The results encourage us to continue the research and to choose genetically modified animals because are closer to the human one.
