Complications and outcomes of gall bladder removal in 20 dogs

Abstract

OBJECTIVE: To report the complications and outcome of dogs undergoing laparoscopic cholecystectomy for uncomplicated gall bladder disease. STUDY DESIGN: Multi-institutional case series. ANIMALS: Client-owned dogs (n=20). METHODS: Medical records of dogs that underwent laparoscopic cholecystectomy were reviewed and signalment, history, clinical and ultrasound examination findings, surgical variables, and complications were collated. Laparoscopic cholecystectomy was performed using a multiport approach. Data were compared between dogs with successful laparoscopic cholecystectomy and dogs requiring conversion to open cholecystectomy. RESULTS: Six dogs (30%) required conversion from laparoscopic to open cholecystectomy due to inability to ligate the cystic duct (3), evidence of gall bladder rupture (1), leakage from the cystic duct during dissection (1), and cardiac arrest (1). Cystic duct dissection was performed in 19 dogs using an articulating dissector (10), right angle forceps (7), and unrecorded (2). The cystic duct was ligated in 15 dogs using surgical clips (5), suture (6), or a combination (4). All dogs were discharged from the hospital and had resolution of clinical signs, although 1 dog developed pancreatitis and 1 dog required revision surgery for bile peritonitis. There was no significant difference in preoperative blood analysis results, surgical technique, or duration of hospitalization between dogs undergoing laparoscopic cholecystectomy and cases converted to open cholecystectomy. CONCLUSION: Laparoscopic cholecystectomy can be performed successfully for uncomplicated gall bladder disease in dogs after careful case selection. The surgeon considering laparoscopic cholecystectomy should be familiar with a variety of methods for cystic duct dissection and ligation to avoid difficulties during the procedure.
