“…Gastric ultrasound has been utilized to identify gastritis, gastric impaction, gastric distension, and gastric neoplasia. [35][36][37][38] The ultrasonographic findings in horses with gastric SCC include visualization of a heterogeneous mural gastric mass in the left side of the abdomen associated with the greater curvature of the stomach, 37,38 similar to 2 of the 3 gastric masses reported here. Metastatic lesions are commonly described in cases of SCC 37-39 and were seen affecting the liver, spleen, omentum, and/or peritoneum in all horses that underwent transabdominal ultrasound examination.…”

Background: Gastric neoplasia of horses is incompletely described. Objective: Provide history, clinical signs, and clinicopathological and pathological findings associated with gastric neoplasia in horses. Animals: Twenty‐four horses with gastric neoplasia. Methods: Retrospective study. History, clinical signs, and clinicopathological and pathologic findings in horses diagnosed histologically with gastric neoplasia were reviewed. Results: Horses ranged in age from 9 to 25 years (median 18 years at presentation). There was no apparent breed or sex predisposition. The most common presenting complaints were inappetance (17/24), weight loss (14/24), lethargy (7/24), hypersalivation (7/24), colic (5/24), and fever (5/24). The most consistent clinical signs were tachypnea (10/19), decreased borborygmi (8/19), and low body weight (7/17). Useful diagnostic tests included rectal examination, routine blood analysis, gastroscopy, abdominocentesis, and transabdominal ultrasound examination. Anemia was the most common hematologic abnormality encountered (7/19), and hypercalcemia of malignancy was seen in 4/16 horses. Squamous cell carcinoma was the most common tumor identified (19/24), and was most often (14/19) found as a single ulcerated, necrotic mass in the nonglandular portion of the stomach. Other gastric neoplasms encountered were leiomyoma (n=2), mesothelioma (n=1), adenocarcinoma (n=1), and lymphoma (n=1). Metastatic neoplasia was found in 18/23 horses. The median time from onset of clinical signs to death was 4 weeks, and all horses died or were euthanized because of gastric neoplasia. Conclusions: Squamous cell carcinoma is the most common primary gastric neoplasia in horses. The survival time after diagnosis of gastric neoplasia in horses is short.

“…This is supported by studies showing that feed deprivation induces squamous mucosal ulceration, especially along the margo plicatus (Murray 1994;Murray and Eichorn 1996). Also, the position of the equine stomach, documented with transabdominal ultrasound, has been shown to change according to the amount of luminal contents (Lores et al 2007). These observations, considered in conjunction, could explain the decrease in proximal gastric pH during the early morning hours without a simultaneous alteration in ventral gastric pH.…”

“…T RANSCUTANEOUS ULTRASONOGRAPHY IS useful for evaluating horses and ponies with gastric disease. [1][2][3][4][5][6][7] Gastric distension with air is performed routinely during gastroscopy to facilitate viewing of the lumen of the stomach. We noticed that the ultrasonographic appearance of the stomach wall is sometimes undulated or folded after gastroscopy.…”

“…4 There was also no reference to this type of change following distension of the equine stomach with fluid. 5 It is important to know and document what happens to the ultrasonographic appearance of the stomach postintervention, in this instance gastroscopy, to determine what is normal or abnormal.…”

Gastroscopy with air insufflation was performed in 10 ponies, after which a transcutaneous ultrasound examination of the stomach and duodenum was performed immediately and at 1, 2, and 4 h postgastroscopy, and 24 h after feeding. Stomach measurements included the dorsoventral and craniocaudal dimensions, as well as the stomach depth from the skin surface and stomach wall thickness at the different time periods. Gastric wall folding was observed in one pony, becoming most distinct 2-4 h postgastroscopy. An undulating stomach wall was noted in eight other ponies postgastroscopy. These observations appeared to be a response to the deflation of the stomach as the insufflated air was released gradually. Gas was detected in the duodenum after the gastroscopy. The parameters measured were noted to be useful to evaluate the extent of stomach distension due to air or feed. The ultrasonographic appearance of the stomach can, therefore, be altered by gastroscopy and this should be borne in mind when examining horses with suspected gastric disease.

Abstract: Results suggested that use of TUS for gastric fluid volume estimation is a potentially useful technique.
