Laparoscopic resection of pancreatic masses in 12 dogs

Abstract

AbstractObjectiveTo describe the surgical management and outcome of dogs undergoing laparoscopic pancreatic mass resection (LPMR).Study designRetrospective study.AnimalsTwelve client‐owned dogs.MethodsData collected from medical records of dogs that underwent LPMR between 2012 and 2023 included signalment, clinical signs, mass location within pancreas, preoperative diagnostic imaging, laparoscopic approach, number of portals and device type used for LPMR, operating time, complications and clinical outcome.ResultsPancreatic tumors were located in the left lobe (7), in the right lobe (4) and in the body of the pancreas (1). A 3‐ or 4‐port technique was used in nine and three dogs, respectively. LPMR was performed with the Ligasure in nine dogs, a harmonic scalpel in two dogs and an endoscopic stapler in one dog. The procedure was performed successfully, with no conversion to open laparotomy, in all cases with a median operating time of 69 min. Postoperative complications occurred in four dogs, which resolved with medical treatments. All dogs survived the surgical procedure, were discharged from the hospital and alive a minimum of 90 days postoperatively. The final follow‐up time ranged between 105 and 245 days (median 147). Histopathological diagnosis included insulinoma (9) and pancreatic carcinoma (3).ConclusionLPMR was performed successfully using a 3‐ or 4‐port technique and was associated with a low complication rate and a good clinical outcome.Clinical significanceLPMR may be considered as an alternative to open celiotomy in dogs, particularly for small tumors located in the distal aspect of the pancreatic lobes.
