Abstract
ERCP is a difficult to teach procedure. Many models have been created for this purpose. The problem with the live anesthetized pig and the CompactEASIE models are the location of the biliary orifice in the first portion of the duodenum and the fact that it differs from the pancreatic duct orifice, limiting the teaching cannulation methods. The chicken heart neo papilla is a good alternative, providing the capability to approach both biliary and pancreatic ducts and perform sphincterotomy. We found some problems with this model: it is unstable in some situations; the tip of the duodenoscope was located too close to the papilla and problems getting the splenic and iliac arteries.
