Q

Piegols VS 2021 - Association between biliary tree manipulation and outcome in dogs undergoing cholecystectomy for gallbladder mucocele: A multi-institutional retrospective study

What was CBD catheterisation associated with?

A

Post-op pancreatitis (regardless if normo or retrograde)

While catheterization of the CBD should still be pursued in light of specific concerns such as lack of integrity or patency of the CBD, routine catheterization in dogs undergoing a cholecystectomy for GBM should be questioned because of possible morbidity.
