Case Study: Minimally Invasive Liver Biopsy in a Dog with Progressive Hepatopathy
An Advanced Surgery Case Study by Katherine Neal, DVM, MS, DACVS
The Case
A senior canine patient was referred to our surgery service for diagnostic evaluation after persistent elevation of liver enzymes despite appropriate medical management. Previous diagnostic workup, including abdominal ultrasound, bile acid testing, and coagulation screening, had not established a definitive diagnosis, and the patient remained clinically asymptomatic.
The goal of surgery was to obtain high-quality diagnostic tissue while minimizing patient morbidity and facilitating a rapid recovery.
Surgical Findings
Diagnostic laparoscopy revealed multiple red-to-tan nodules distributed throughout several hepatic lobes without evidence of other significant intra-abdominal abnormalities.
Using a Single Incision Laparoscopic Surgery (SILS) approach, Dr. Katherine Neal obtained multiple full-thickness liver biopsies from separate hepatic lobes. Samples were submitted for:
- Histopathology
- Quantitative hepatic copper analysis
- Aerobic culture
- Anaerobic culture
Following confirmation of hemostasis, the procedure was completed through the same small incision. Anesthesia and recovery were uneventful.
Why Choose Laparoscopic Liver Biopsy?
For patients with diffuse hepatopathies, laparoscopic biopsy provides excellent diagnostic yield while minimizing surgical trauma.
- Magnified visualization of the liver and abdominal cavity
- Ability to obtain biopsies from multiple liver lobes
- Reduced postoperative discomfort
- Small incision with improved healing
- Rapid recovery with same-day discharge in many patients
- Excellent tissue quality for histopathology and quantitative copper analysis
Outcome
The patient recovered comfortably from anesthesia, required only oral pain management, and was discharged the same day. Ongoing treatment recommendations will be guided by histopathology, quantitative copper analysis, and culture results in collaboration with the primary care veterinarian.
Clinical Pearl
Elevated liver enzymes with nonspecific imaging findings often require histopathology for definitive diagnosis. Laparoscopic liver biopsy provides excellent diagnostic tissue while reducing patient morbidity and shortening recovery compared with traditional exploratory surgery.
