Question 12

Putterman, vet surg 2021
Influence of normograde versus retrograde catheterization of bile ducts in dogs treated for gallbladder mucocele

-what factors resulted in a reduction in complication?

Answer 12

dogs catheterised normograde had more post op complications (including persistence of GI signs), and the presence of a diplomat at surgery reduced intra and post op complications

Answer 16

-incision extending to thorax, often associated with a right divisions.
-post op complications less likely when used TA stapler by specialist surgeon and in bigger dogs.
Complications less likely with left sided masses.
TA stapler reduced odds of complication by 19x.
