Use of a bipolar vessel-sealing device in resection of canine insulinoma

Abstract

OBJECTIVES: To describe partial pancreatectomy using a bipolar vessel-sealing device (BVSD) and compare this novel technique to the conventional suture-fracture (SF) method for canine insulinoma. METHODS: Pre-, intra- and postoperative data of eight dogs with insulinoma, which underwent resection using the BVSD (LigaSure V), were prospectively collected and compared with those of eight randomly selected case-matched patients that underwent resection using the conventional SF technique. RESULTS: Mean surgical time was significantly (P=0·022) shorter in the BVSD (107 ±9 minutes) than in the SF (135 ±22 minutes) group. The BVSD technique was negatively associated with surgical time and duration of the hospitalisation period. Neither technique caused intraoperative complications, such as bleeding, collateral damage to adjacent tissues or problems with sealing or suturing the pancreatic tissue. Three dogs in the SF group and none in the BVSD group developed postoperative clinical signs associated with pancreatitis. CLINICAL SIGNIFICANCE: BVSD is a safe and viable alternative to conventional methods of pancreatectomy for canine insulinoma. It provides the possibility to remove insulinomas in the pancreatic limbs and corpus with relative ease. BVSD pancreatectomy in dogs with insulinoma significantly decreases operative and hospitalisation times and is not associated with more clinical complications than SF pancreatectomy
