Video capsule endoscopy (VCE) is a non-invasive imaging modality with reported applications including identification of mucosal lesions not detected with traditional endoscopy or abdominal imaging and evaluation of anthelmintic efficacy. In people, VCE is used in diagnostic and management protocols of various gastrointestinal disorders, particularly in obscure gastrointestinal bleeding or unexplained iron deficiency anemia (IDA). The objective of this study was to evaluate the use of VCE in dogs with microcytosis.

Medical records were reviewed to identify dogs with microcytosis that received VCE without a defined etiology based on other imaging. Signalment, history, physical examination findings, clinicopathologic data, and capsule endoscopy findings were recorded.

Dogs were 8 to 12 years old, 6.9-40 kg, and a mix of sexes and breeds. Clinical signs included pica, melena, hematochezia, vomiting, diarrhea, and hyporexia. Abdominal radiographs and abdominal ultrasound were unremarkable in all dogs. Esophageal transit time, gastric emptying time, and small intestinal transit time was: 5-14 minutes, 18-451.30 minutes, and 67.5-228 minutes, respectively. Mucosal lesions were identified in 8/9 dogs. Gastric lesions included erosion/ulcers (7), hemorrhage (2), mucosal irregularity (5), and a polypoid lesion (1). Intestinal lesions included erosions (3), hemorrhage (1), irregular mucosa (5), and a mass in the duodenum (1) and jejunum (1). Colonic lesions included an irregular mucosa (1).

VCE identified lesions not detected with other diagnostic modalities in 8/9 dogs with microcytosis of unknown origin. VCE is a non-invasive diagnostic tool that could assist in the identification of gastrointestinal lesions in dogs presenting with microcytosis when other diagnostic modalities are inconclusive.
