Repair of a sliding (type I) hiatal hernia in a cat via herniorrhaphy, esophagoplasty and floppy Nissen fundoplication.

Case Summary: A 10-month-old domestic shorthair cat was evaluated for severe esophagitis and protracted vomiting and regurgitation secondary to a sliding (type I) hiatal hernia. The hernia and concurrent upper airway obstruction (nasopharyngeal polyp) were diagnosed with a multi-modality approach, including thoracic and abdominal radiographs, abdominal ultrasound, computed tomography and endoscopy. Following unsuccessful attempts at medical management, lower esophageal incompetence was successfully treated by employing a combination of surgical techniques, including herniorrhaphy, esophagopexy and modified (floppy) Nissen fundoplication.

Association between macroscopic appearance of liver lesions and liver histology in dogs with splenic hemangiosarcoma: 79 cases (2004-2009).

Medical records for 79 dogs with confirmed splenic hemangiosarcoma (HSA) following splenectomy were reviewed for information regarding either the presence or absence of macroscopic liver lesions and the histopathological characteristics of the liver. Only 29 of 58 dogs (50%) with grossly abnormal livers had HSA metastasis. No dogs with grossly normal livers had metastasis detected on liver pathology.

Ulnar osteosarcoma in dogs: 30 cases (1992-2008).

Objective: To examine the biological behavior of ulnar osteosarcoma and evaluate predictors of survival time in dogs.

Design: Retrospective case series.

Animals: 30 dogs with primary ulnar osteosarcoma.

Use of local and axial pattern flaps for reconstruction of the hard and soft palate.

There are numerous conditions that may result in defects of the hard and soft palate. Reconstruction of these defects may be difficult due to anatomical limitations and limited tissue availability. The majority of palate defects, even when large, may be closed using local and/or axial pattern flaps, while other more advanced techniques such as free tissue transfer and prosthetic implants are required in a smaller number of cases.

Hiatal hernia controversies--a review of pathophysiology and treatment options.

Objective: To provide a detailed discussion of the aetiology and pathophysiology of hiatal hernia in both humans and small animals, and review current medical and surgical treatments.

Design: Review article.

Summary: Hiatal hernia is not completely understood in humans or animals.
