Choledochal tube stenting for decompression of the extrahepatic portion of the biliary tract in dogs: 13 cases (2002–2005)

Abstract

Choledochal tube stenting is an effective method of decompression of the extrahepatic portion of the biliary tract in dogs and provides a less complex alternative to traditional cholecystoenterostomy techniques in select cases.

Initial experience with endoscopic retrograde cholangiography and endoscopic retrograde biliary stenting for treatment of extrahepatic bile duct obstruction in dogs

“…2,[6][7][8][9] Endoscopic retrograde sphincterotomy with biliary stenting is considered the treatment of choice for many of these conditions. [14][15][16][17][18][19] Surgical biliary diversion techniques in dogs and cats have been associated with a 25% to 73% and 50% to 75% mortality rate, respectively.

“…[2][3][4]6,8,[10][11][12][13] Traditional reported treatment for EHBDO in veterinary small animal patients involves laparotomy with surgical manipulation of the CBD and pancreatic duct via choledochotomy, diversion procedures such as cholecystoenterostomy, or surgical stent placement across the MDP. [14][15][16][17][18][19] When a traditional open surgical approach was used for the placement of biliary stents, the mortality rate has been reported to be 30.7% in dogs 16 and 28% in cats, 17 respectively.

Prolonged anesthesia times (median, 3.5 hours; range, 2.4 to 6.75 hours) 16 and manipulation of the pancreatic and biliary system in unstable patients may contribute to the high morbidity and mortality rates reported with traditional rerouting surgery or open surgical stent placement.

[14][15][16][17][18][19] In human patients, similar risks and complications of traditional open surgeries in debilitated patients have led to the use of interventional radiology-guided procedures (eg, placement of cholecystostomy tubes and percutaneous biliary stenting) and interventional endoscopy techniques (eg, ERCP and biliary stenting) in an effort to minimize procedure-related complications.

Liver and biliary tract

“…Five of the seven cats survived to discharge but there was a greater morbidity associated with this technique in cats than previously described in dogs, most likely due to differences in the pathogenesis of these diseases. 108,109 Cholecystotomy/dochotomy pathology. 97 In this report, three of the cats had dysfunction associated with pre-existing inflammatory bowel disease, two had inspissated bile causing an obstruction, and one cat was diagnosed with cholangiocellular carcinoma.…”
