Pancreatography Retrograde

Retrograde pancreatography (RP) is classified as an invasive examination, which makes its use limited. The RP is as follows. First, a pyelorenal siphon with a contrast agent is performed, then the intestinal contents are evacuated through a gastrostomy or stoma, and a radiocontrast agent is injected through them with a syringe. The retrograde contrast obtained in this way from the stomach enters the duodenum and is secreted by the pancreas, then causing a shadow resembling an inverted question letter “e”. This leads to true enlightenment of the head of the gland. If there is no diagnostic value of RP, it is immediately followed by a PCI of the gastrointestinal tract (initiated by it) or a traditional PC. mistletoe. Having ensured the patency of the bile ducts during their preparation before this, during the inflation of the duodenum for the best demonstration of the shadow of the head of the pancreatic-duodenal duct, the piston is removed and its original position is maintained in the colonostomy or stoma before contrasting and returned to it with the start of the study. At the end of the RP, the appropriate point is selected under fluoroscopy control and the head of the pancreas is punctured (under control), removing material for histological examination.
