Results: Twenty-two dogs were included. No complications were reported during the laparoscopic procedure. The median number of portal triads per needle biopsy specimen was 6 (range, 4 to 8) compared to 20 (range 14;25) with wedge biopsy specimen. The median length of needle biopsy specimens was 10 mm; (range, 6 to 16 mm) and 6 mm for all wedge biopsies. On the basis of biopsy interpretation, the diagnosis was overall similar with the two methods: 8 dogs had vacuolar hepatopathy, 4 acute cholangitis, non-specific acute form in 3 dogs. Chronic hepatitis with cirrhosis was found in 2 cases, 3 dogs had diffuse neoplasia and 2 miscellaneous hepatic disorders. The fibrosis was considered to be severe in 3 dogs, moderate in 3 dogs and mild in 11 dogs. No quantitative and qualitative difference was observed between the two types of biopsies specimen.
