Ultrasonographic appearance of retained surgical sponges and gauzes in the acute postoperative period: a phantom and cadaveric study.

Retained surgical sponges or gauzes (RSS) are an uncommon complication of exploratory laparotomy surgery and pose a clinically significant risk to the patient. The purpose of this two-part, prospective, descriptive study was to describe the previously uncharacterized ultrasonographic appearance of RSS in phantom and cadaveric models of the acute postoperative period (24-48 h). For the first part of the study, a gelatin phantom containing a woven gauze with a radiopaque marker (radiopaque gauze), a woven gauze with no marker (nonradiopaque gauze), and a laparotomy sponge with a radiopaque marker (radiopaque sponge) was evaluated with ultrasonography.

Computed tomographic features of confirmed gallbladder pathology in 34 dogs.

Gallbladder pathology is common in dogs, but published studies describing the computed tomographic (CT) appearance of many gallbladder pathologies are currently lacking. This retrospective, multicenter, cases series, descriptive study evaluated the CT features of confirmed gallbladder pathology in 34 dogs. In this subset of dogs, the most common pathologies included cystic mucosal hyperplasia (15/34, 44.

Concurrent bullous emphysema, bronchointerstitial pneumonia with necrosis, and tension pneumothorax in an 8-week-old puppy.

An 8-week-old, male, mixed breed puppy was presented because of progressive respiratory distress. Thoracic radiographs revealed innumerable coalescing pulmonary bullae throughout the lungs with increased soft tissue opacity of the remaining pulmonary parenchyma and tension pneumothorax. Necropsy and histopathological findings were compatible with bullous emphysema and marked neutrophilic to histiocytic bronchointerstitial pneumonia with necrosis, bronchiectasis, fibrosis, dystrophic mineralization, and vasculitis with thrombosis.
