Laparoscopic partial pancreatectomy of the left limb using a harmonic scalpel in nine cats

Abstract

AbstractObjectiveTo describe a laparoscopic technique and outcome for partial pancreatectomy in cats.Study designProspective cohort study.AnimalsNine cats.MethodsLaparoscopic pancreatectomy was performed using a single incision laparoscopic surgery port and an additional 5.5 mm port. The left pancreatic limb was dissected, sealed and divided at the level of the splenic vein insertion to the portal vein using a harmonic device. Surgical time and complications were recorded. The weight and length of the resected pancreatic limb was recorded. Pre‐ and postoperative trypsin‐like immunoreactivity (TLI), pancreatic lipase immunoreactivity (PLI), and hemoglobin A1C were documented.ResultsLaparoscopic partial pancreatectomy was performed successfully in all cats. One grade 1 intraoperative complication occurred (1/9; 11%) resulting in minor hemorrhage from a caudal splenic vein branch. A grade 2 postoperative complication occurred within 3 days after surgery in one cat (1/9; 11%), involving localized, sterile peritonitis in the region of the pancreatic angle. Signs resolved with conservative management. No cats exhibited signs of pancreatitis postoperatively. Long‐term, mean TLI decreased by 37% ± 38% (p = .03) following partial pancreatectomy, while PLI and A1C were unchanged. All cats were alive and clinically well at last follow‐up 250 to 446 days following surgery.ConclusionsLaparoscopic partial pancreatectomy using a harmonic device is effective in cats, and offers a minimally‐invasive alternative to open surgical pancreatectomy techniques. Laparoscopic pancreatectomy of the left limb results in adequate exocrine and endocrine function in the long‐term.
