Left pancreaticoduodenostomy after removal of the right lobe and the head of the pancreas in a cat.

OBJECTIVE: To report a surgical technique for pancreaticoduodenostomy and its outcomes in a cat. ANIMALS: A 14-year-old domestic cat. STUDY DESIGN: Case report. METHODS: A cat was referred to our hospital with a large abdominal mass. On ultrasonographic examination, this mass was identified as a large fluid-filled cavity in place of the right pancreatic duct and involved the pancreatic and accessory pancreatic ducts. A small echoic cavity was observed in the left pancreatic lobe. Serous fluid was collected from the large cavity. On cytology, the small cavity was consistent with an abscess. A partial left pancreatectomy was performed to remove the abscess. The large cavity was excised with the remnant of the right pancreatic lobe and body. After ligation of the pancreatic ducts, the left pancreatic duct was isolated and an end-to-side pancreaticoduodenostomy was performed. RESULTS: The cat recovered without complications. Histological examination was consistent with chronic pancreatitis and peripheral inflammation. No evidence of postoperative pancreatic insufficiency was detected on clinical examination or laboratory findings. A focal ampulla-like dilation of the pancreatic duct was noted on ultrasonography, with no other complications at the anastomosis. The cat presented 225 days postoperatively with respiratory distress. Multiple nodules were identified throughout the lung parenchyma on radiographs. Abnormalities on ultrasonographic examination included an enlarged liver infiltrated with nodules. Due to poor prognosis, the cat was euthanized. Final histopathological diagnosis was diffuse carcinoma. CONCLUSION: Pancreaticoduodenostomy restored pancreaticointestinal continuity after extensive pancreatectomy involving the pancreatic ducts and resulted in long-term survival in the cat reported here.

Excellent long-term clinical outcome in a young athletic dog following surgical complications of a comminuted patellar fracture and patellar ligament rupture.

A 1-year-old athletic golden retriever dog was presented for a non-weight-bearing right pelvic limb lameness that occurred during a canicross race. Orthopedic examination revealed pain and inflammation of the right stifle joint. Radiographs showed a traumatic comminuted patellar fracture. Surgery was elected and a midsubstance patellar ligament rupture was also identified. Surgical management consisted of a combination of techniques for patellar fracture fixation and primary patellar ligament reconstruction. All orthopedic implants were removed secondary to implant failure. Postoperative 20-month radiographic follow-up revealed patella alta and non-union of the fracture. However, an excellent clinical outcome was achieved with a complete return to a high activity level. Key clinical message: Surgical stabilization of patellar fractures is usually a significant challenge. A return to apparent normal limb function was achieved in this dog suffering complex patellar fracture with concomitant patellar ligament rupture despite postoperative fracture non-union.

Excellents résultats cliniques à long terme chez un jeune chien athlétique suite à des complications chirurgicales d'une fracture patellaire comminutive et d'une rupture du ligament patellaire. Un golden retriever athlétique âgé d'un an a été présenté pour une boiterie de suppression d'appui du membre pelvien droit survenue lors d'une course de canicourse. L'examen orthopédique a révélé une douleur et une inflammation du grasset droit. Les radiographies ont montré une fracture patellaire comminutive traumatique. Une chirurgie a été recommandée et une rupture du ligament patellaire à son tiers moyen a également été identifiée. La prise en charge chirurgicale consistait en une combinaison de techniques pour réaliser la réduction de la fracture patellaire et la reconstruction primaire du ligament patellaire. Tous les implants orthopédiques ont été retirés suite à des complications associées au matériel d'ostéosynthèse. Le suivi radiographique postopératoire à 20 mois a révélé une patella alta et une nonunion de la fracture. Un excellent résultat clinique a cependant été obtenu avec un retour complet à un niveau d'activité physique élevé.Message clinique clé :Les fractures patellaires sont rares chez le chien et la stabilisation chirurgicale est généralement un défi important. Selon les auteurs, seuls quelques rapports cliniques avec des suivis à court et moyen terme sont disponibles dans la littérature. Un retour à une fonction apparemment normale du membre a été obtenu chez ce patient souffrant d'une fracture patellaire complexe avec rupture concomitante du ligament patellaire malgré la non-union de la fracture en postopératoire.(Traduit par Dre Dominique Gagnon).

Removal of lower urinary tract stones by percutaneous cystolithotomy: 68 cases (2012-2017).

OBJECTIVE: To describe the use and outcome of percutaneous cystolithotomy (PCCL) for removal of urethral and bladder stones in dogs and cats. STUDY DESIGN: Retrospective case series. ANIMALS: Sixty-eight client-owned dogs and cats. METHODS: Records were reviewed and analyzed for dogs and cats that underwent PCCL between January 2012 and December 2017. Signalment, clinical presentation, laboratory and imaging data, procedure time, use of lithotripsy, biopsy, perioperative and immediate postoperative complications, hospitalization times, stone composition, and urine culture results were recorded. Owners were contacted by phone or email 3 weeks after the procedure. Follow-up communications with the owner and referring veterinarian were also recorded. RESULTS: Seventy percutaneous cystolithotomies were performed in 59 dogs and nine cats. The median duration of the procedure was 95 minutes (45-420), and lithotripsy was required in 3% (2/70) of PCCL. Complications during the procedure were reported in one case. In eighty-three percent of procedures (58/70), animals were discharged within 24 hours postoperative. Twenty-four percent (16/68) of animals had minor complications (lower urinary tract signs), and one dog had a major complication (surgical wound dehiscence) during the 3 weeks after the operation. Long-term follow-up revealed stone recurrence in 21% of cases followed more than a year after the procedure (7/33). CONCLUSION: Percutaneous cystolithotomy allowed removal of bladder and urethral stones with rapid postoperative recovery and few major perioperative or short-term postoperative complications. CLINICAL SIGNIFICANCE: Percutaneous cystolithotomy provides an attractive minimally invasive surgical alternative for removal of lower urinary tract stones in small animals.
