“…E ndoscopic retrograde cholangio‐pancreatography is a combination of endoscopy and fluoroscopy to perform radiographic imaging of the biliary and pancreatic duct systems. This technique is technically possible in dogs 1–5 . In humans, endoscopic retrograde cholangiography is used for determination of the cause of extrahepatic cholestasis, and for preparation, implementation, and postoperative control of gallbladder surgery.…”

Endoscopic retrograde cholangio-pancreatography is a combination of endoscopy and fluoroscopy used for radiographic imaging of the biliary and pancreatic ducts. In order to assess its feasibility and to describe abnormal findings in dogs, this technique was performed in 30 dogs with nonspecific chronic gastrointestinal disturbances. Using an 11-mm side-view endoscope, retrograde cholangiography was successful in 20/30 dogs (67%) and pancreatography in 21/30 (70%). Success was affected by intraduodenal food, mucus or blood, problems in papillary cannulation, stomach overdistention, body size, and changes in duodenal mucosa. It was impossible to perform the procedure in dogs weighing < 10 kg with the available material. Endoscopic retrograde cholangiography revealed findings that differed from previous reports in healthy beagles in 5/20 dogs. Findings included enlarged common bile duct (n = 2), intraductal filling defects (n = 2), and deviated course of common bile duct (n = 1), and major papilla stenosis (n = 1). In the dog with major papilla stenosis and intraductal filling defects, endoscopic guided sphincterotomy was performed. Endoscopic retrograde pancreatography revealed an abnormal course of the accessory pancreatic duct in 2/21 dogs. In both dogs with proven end-stage pancreatic acinar atrophy, the left duct branch did not run distal the stomach to the left but went parallel to the right duct branch and the duodenum. Repeated clinical and laboratory examinations revealed no signs of complications after endoscopic retrograde cholangio-pancreatography. It was concluded that this imaging technique is promising for the diagnosis of biliary and pancreatic diseases in dogs. It also offers the chance for new treatment options such as endoscopic guided sphincterotomy in dogs.

“…Retrograde contrast filling of the biliary or pancreatic duct system was possible in 40% of dogs 26 . In another study on endoscopic retrograde pancreatography, almost identical radiographic appearance of in vivo endoscopic retrograde and post‐mortem pancreatograms was found in six dogs 27 . In a third study, endoscopic retrograde pancreatography was performed in a canine model for assessment of pancreatic imaging by computed tomography (CT) after endoscopic retrograde pancreatography.…”

Endoscopic retrograde cholangiography and pancreatography was performed in seven healthy Beagles to assess the common bile duct and the accessory pancreatic duct after retrograde filling with an iodine contrast medium. All dogs had a major and a minor duodenal papilla. One Beagle had additionally an accessory papilla. The diameter of the contrast filled ducts was measured at three defined measure points (MP1-3) in ventrodorsal radiographs and left lateral radiographs. In ventrodorsal radiographs of endoscopic retrograde cholangiography the common bile duct had a straight craniomedial course. The mean duct diameter was from proximal to distal 3.04 +/- 1.89mm at MP1, 2.38 +/- 1.23 mm at MP2, and 2.11 +/- 0.84 mm at MP3. In ventrodorsal radiographs of endoscopic retrograde pancreatography, the left and right branch of the accessory pancreatic duct united in the pancreatic body. The mean diameter of the right branch was 0.88 +/- 0.14 mm at MP1, 0.72 +/- 0.2 mm at MP2 and 0.61 +/- 0.11 mm at MP3. The left branch had a diameter of 0.93 +/- 0.28 mm at MP1, 0.86 +/- 0.21 at MP2, and 0.6 +/- 0.07 mm at MP3. The mean length was 81.6 +/- 14.3 mm for the right and 107.0 +/- 24.9mm for the left branch. In left lateral radiographs of endoscopic retrograde pancreatography, it was not possible to differentiate the left from the right branch. Both branches ran nearly parallel and showed similar diameters but slight differences in length. The study proves that endosopic retrograde cholangio-pancreatography is possible in dogs. Radiographs taken from dogs in dorsal recumbency allow an objective assessment of the common bile duct and the accessory pancreatic duct.

“…For ethical rea sons, it has become difficult to obtain a ref erence material of 'normal' pancreatograms [4]. Post-mortem pancreatograms have been studied [5,6], but as autolysis takes place rapidly, data obtained can be questioned. Increasing ductal size is found with increas ing age [7], Kasugai et al [8] analysed the pancreato grams from a large number of patients with pancreatitis and established three categories of lesions in chronic pancreatitis.…”

The incidence of pancreatitis has been increasing during the last decennium paralleling a rapid enhancement in alcohol consumption. For many years, diagnostic criteria of chronic pancreatitis were exclusively based on the estimation of the exocrine pancreatic function. New valuable information is provided from endoscopic retrograde pancreaticography (ERP) and pancreatic ultrasonography. In a consecutive series of patients with chronic alcoholism changes in the pancreatogram were demonstrated in approximately 44% of the patients. A comparative study of ERP and exocrine pancreatic function showed that only patients with advanced pancreatic lesions had a significant reduction in pancreatic function. It is suggested that ‘subclinical pancreatitis’ is frequent among alcoholics. Complementary use of pancreatic ultrasonography and ERP gives a differentiated picture of pancreatic disease and is recommended among the first steps in the diagnostic chain for pancreatic disease.
