Abstract
The present study aimed to evaluate the use of venous graft in reconstruction of completely lost segments of common bile duct in dogs. Thirty adult apparently healthy stray dogs were used. They were randomly divided into the following three groups : Group I (control group), this had choledochojejunostomy as a Roux-en-L anastomosis after the transection of the common bile duct with ligation of the distal stump of the duct. Group IIA had external jugular vein autograft as a substitute to the transected segment of the common bile duct with bilateral end-to-end anastomosis without stenting. Group IIB had external jugular vein autograft as a substitute to the transected segment of the common bile duct with bilateral end-to-end anastomosis with stenting by using a silastic tube ”part of a feeding tube no. 5”. The results of the study revealed that there are no significant differences between the three groups regarding all the studied non-parametric data (immediate mortality, total mortality, morbidity, radiological findings and pathological findings). However, different levels of significant differences were found between the three groups regarding all the laboratory liver function tests..
