|January 1, 1978
Summary
Liver hilus dearterialization in dogs showed that removing the gallbladder significantly reduced intra-abdominal complications. Angiography ensured complete arterial control during the procedure.
Area of Science:
- Veterinary Surgery
- Surgical Oncology
- Hepatic Artery Interventions
Background:
- Liver hilus dearterialization is a complex surgical procedure.
- Potential complications include gallbladder issues and peritonitis.
- Angiography is crucial for precise arterial control.
Purpose of the Study:
- To evaluate the impact of cholecystectomy on complications following liver hilus dearterialization in dogs.
- To assess the efficacy of pre- and post-procedural angiography in controlling hepatic artery ligation.
Main Methods:
- Standardized liver hilus dearterialization was performed on 21 dogs, with 7 also undergoing cholecystectomy.
- Sham-operated dogs served as controls.
- Repeat laparotomies and selective hepatic angiography were conducted.
- Angiography was used to identify and confirm ligation of all hepatic artery tributaries.
Main Results:
- Dogs without cholecystectomy experienced high rates of gallbladder gangrene, perforation, and bile peritonitis.
- Cholecystectomy significantly decreased intra-abdominal complications.
- No significant changes in basic liver microscopic structure were observed.
- Angiography effectively identified and confirmed ligation of all hepatic artery branches.
Conclusions:
- Concurrent cholecystectomy is recommended during liver hilus dearterialization to mitigate gallbladder-related complications.
- Pre- and post-procedural angiography provides essential control for hepatic artery dearterialization.
- The surgical technique did not adversely affect the liver's fundamental microscopic integrity.
