Wireless Capsule Endoscopy in Enteropathy Induced by Nonsteroidal Anti-inflammatory Drugs in Pigs

AimThe aim of this study is to evaluate the diagnostic yield of capsule endoscopy in nonsteroidal anti-inflammatory drug (NSAID)-induced enteropathy in pigs.Materials and MethodsIndomethacin (400 mg/day) was administrated orally for 10 days to eight female pigs weighing 36.3 ± 2.4 kg. Afterwards, capsule endoscopy was performed, using the EndoCapsule system (Olympus Optical Co., Tokyo, Japan). The following morning, pharmacological euthanasia and immediate autopsy were performed.ResultsSmall bowel injury compatible with NSAID-induced enteropathy was observed in 7/8 animals. The most common lesions were red spots and erosions. Ulcers and small intestinal bleeding were identified sporadically. Sensitivity and specificity of capsule endoscopy were 83.3% and 95.8%, respectively.ConclusionOur results indicate that wireless capsule endoscopy is a highly accurate noninvasive method for evaluation of experimental NSAID-induced enteropathy.
