“…This recommendation, which is generally accepted in veterinary medicine, arises from the ‘nil by mouth from midnight’ rule historically used in human medicine [ 15 ]. Gastric emptying times of 7–15 h have been reported in dogs [ 16 ]. However, several studies have shown that fasting does not necessarily result in an empty stomach [ 15 ].…”

Background: Gastroesophageal reflux (GER) has been reported to be a common finding in dogs under general anesthesia. Objectives: The aim of this retrospective study was to assess the esophageal and gastric contents in a population of dogs undergoing computed tomographic myelography (myelo-CT) examination and to evaluate the factors influencing the presence of esophageal fluid (gastric content, duration of anesthesia, body position, and intrinsic factors). Methods: Esophageal and gastric contents of 83 non-brachycephalic dogs were retrospectively assessed based on plain and myelo-CT scans. Age, weight, breed, sex, and the time between the 2 computed tomography [CT] scans were included. Results: Esophageal fluid was present in 19% (16/83) of the animals, and 14% (12/83) and 46% (37/83), respectively, had fluid or food material in their stomachs. The frequency of observing esophageal fluid on myelo-CT scans was significantly increased compared with plain CT scans (p = 0.006). The presence of gastric fluid was significantly associated with an increased frequency of observing esophageal fluid compared to other gastric contents (p = 0.049; odds ratio, 3.1). The presence of esophageal fluid was not correlated with alimentary gastric contents (p = 0.17). Increased body weight and duration of anesthesia were significantly associated with an increased frequency of observing esophageal fluid (p = 0.022, p = 0.021). Conclusions: Unlike alimentary gastric contents, fluid gastric contents were correlated with the presence of esophageal fluid upon myelo-CT. The observation of fluid in the esophagus may be consistent with GER. This study provides data additional to pH monitoring studies of GER and may support previous studies recommending shorter pre-anesthetic fasting periods in dogs.

Gastric leiomyoma (GL) is an uncommon benign neoplasm found in older dogs and generally identified as an incidental finding. The purpose of this paper is to describe the imaging appearance of GL in different diagnostic imaging modalities (radiography [XR], ultrasonography [US] and computed tomography [CT]). All three modalities revealed a mass arising within the gastric wall, radiopaque on XR, hypoechoic on US and isoattenuating on CT, with intralesional radiopaque/hyperechoic/hyperattenuating foci, respectively. US and CT are sensitive and proved very useful in the diagnosis of this type of neoplasia, identifying the location, extent and appearance of the mass before a surgical treatment. GL should be considered as a possible diagnosis in the presence of dystrophic mineralisation within a gastric mass.

Gastric dilatation and volvulus (GDV) is a life‐threatening emergency that requires urgent intervention. Radiographic features associated with 360‐GDV in dogs have not been investigated. The aim of this retrospective observational study is to describe radiographic features and clinical variables in dogs affected with 360‐GDV and to report agreement rates between different radiologists. We also report the sensitivity and specificity of radiographs to diagnose 360‐GDV in dogs. Confirmed 360‐GDV cases were retrieved, and the radiographic findings were compared with dogs presenting with gastric dilatation (GD) and 180‐GDV. Images were reviewed and graded by three blinded board‐certified radiologists. A total of 16 dogs with confirmed 360‐GDV were identified. The median age was 10 years old (2–13 years). The sensitivity for detection of 360‐GDV ranged between 43.7% and 50%, and the specificity between 84.6% and 92.1%. Interobserver agreement on final diagnosis was substantial (Kappa = 0.623; 0.487–0.760, 95% CI). The highest agreement rate was in cases of 180‐GDV (87%), followed by the GD cases (72%) and 360‐GDV (46%). Severe esophageal distension and absence of small intestinal dilation were the only radiographic features specifically associated with 360‐GDV. A similar pyloric position was found between GD and 360‐GDV. Additional radiographic variables that could help differentiate GD from 360‐GDV include the degree of gastric distension and the peritoneal serosal contrast. Two cases with 360‐GDV were misdiagnosed by the three radiologists as GD. In conclusion, radiographically, 360‐GDV cases can reassemble GD and vice versa. Radiologists and clinicians should be aware of the low sensitivity of radiographs for the detection of 360‐GDV.
