Laparoscopic partial pancreatectomy in a cat with exocrine pancreatic carcinoma

CASE SUMMARY: Minimally invasive surgery is an increasingly popular alternative to open surgery in veterinary medicine. Compared with traditional surgical approaches, laparoscopic pancreatectomy provides a less invasive approach and has several potential benefits, including improved visualization, reduced infection rate and decreased postoperative pain. Laparoscopic partial pancreatectomy has been described in humans, dogs and pigs but not cats. Pancreatectomy with or without chemotherapy is a treatment option for exocrine pancreatic carcinoma, a rare but malignant cancer in cats. We report the case of a 16-year-old male neutered domestic longhair cat diagnosed with exocrine pancreatic carcinoma that was treated with laparoscopic partial pancreatectomy, carboplatin and toceranib phosphate. A three-port technique using a 5 mm 0º telescope and bipolar vessel sealing device was performed to remove the entire left limb of the pancreas. No intra- or postoperative complications occurred, and the patient was discharged the following day. Forty days postoperatively, the patient received its first of five doses of carboplatin, which were given every 4–5 weeks over a period of 4 months. A maintenance protocol of toceranib phosphate was started after completion of carboplatin treatment. At the time of this article being submitted, the patient had survived for more than 221 days. RELEVANCE AND NOVEL INFORMATION: This is the first report of a laparoscopic partial pancreatectomy performed on a feline patient for pancreatic carcinoma.
