OBJECTIVE: To describe the operative technique, complications, and conversion rates for laparoscopic liver biopsy (LLB) in dogs and evaluate short-term clinical outcome for dogs that underwent the procedure.
DESIGN: Retrospective case series.
ANIMALS: 106 client-owned dogs.
PROCEDURES: Medical records were reviewed to identify dogs that underwent an LLB with a single-port or multiport technique at either of 2 veterinary teaching hospitals from August 2003 to September 2013. Demographic and laboratory data, preoperative administration of fresh frozen plasma, procedural and diagnostic information, intraoperative complications, and survival to discharge were recorded. The LLB specimens were obtained with 5-mm laparoscopic biopsy cup forceps and a grasp-and-twist technique.
RESULTS: Prior to surgery, 25 of 94 (27%) dogs had coagulopathy (prothrombin time or partial thromboplastin time greater than the facility reference ranges, regardless of platelet count). Twenty-one dogs were thrombocytopenic, 14 had ascites, and 14 received fresh frozen plasma transfusion before surgery. In all cases, biopsy samples collected were of sufficient size and quality for histopathologic evaluation. Two dogs required conversion to an open laparotomy because of splenic laceration during initial port placement. One hundred one of 106 dogs survived to discharge; 5 were euthanized during hospitalization owing to progression of liver disease and poor prognosis.
CONCLUSIONS AND CLINICAL RELEVANCE: Single-port and multiport LLB were found to be effective, minimally invasive diagnostic techniques with a low rate of complications. Results suggested LLB can be safely used in dogs with underlying coagulopathies and advanced liver disease.
