Objective: To describe the paracostal approach to caudate liver lobectomy in rabbits and compare the outcome of paracostal versus ventral midline approach for caudate liver lobectomy in rabbits with caudate liver lobe torsion (LLT).

Study Design: Cadaveric and retrospective study.

Animals: Normal rabbit cadavers (n = 5) and rabbits with caudate LLT (n = 22).

Computed tomography of testicular torsion in a juvenile dog with unilateral cryptorchidism.

A 14-week-old male unilaterally cryptorchid Clumber spaniel was presented for acute lethargy. Physical examination revealed abdominal pain, and a single testis was palpated in the scrotum.

Incidence, survival time, and surgical treatment of parathyroid carcinomas in dogs: 100 cases (2010-2019).

Objective: To evaluate outcomes of dogs with parathyroid carcinoma (PTC) treated by surgical excision and to describe the incidence of postoperative hypocalcemia, degree of hypocalcemia, duration of hospitalization, duration of calcium supplementation, and survival time.

Animals: 100 client-owned dogs with PTC admitted to academic, referral veterinary institutions.

Procedures: In a retrospective multi-institutional study, medical records of dogs undergoing surgical excision of PTC between 2010 to 2019 were reviewed.
