Panintestinal capsule endoscopy in patients with celiac disease. INTRODUCTION: Capsule endoscopy has proven its utility in diagnosing villous atrophy and lymphoma in patients with celiac disease. Recently, a novel capsule endoscopy system was introduced which enables the examination of the small and large bowel. So far, it has not been evaluated in patients with celiac disease. OBJECTIVE: The primary objective of this study was to evaluate the novel panintestinal capsule endoscopy system in patients with celiac disease. METHODS: Eleven patients with histologically proven celiac disease (Marsh 0-IV), who underwent a panintestinal capsule endoscopy between March 2018 and April 2019 at our institution, were included in this retrospective single-center study. All patients performed standard bowel preparation prior to the examination. Diagnostic yield, safety and therapeutic impact were analyzed. In addition, the correlation between capsule endoscopy findings and the histology of the duodenal mucosa was assessed. RESULTS: Panintestinal capsule endoscopy was feasible and produced an acceptable visualization quality in all cases. Concordance of capsule endoscopy findings with the Marsh classification showed a good correlation (r = 0.8). No lymphomas were detected. Evaluation of the colon revealed diminutive polyps (median size 4 mm) in 18% of patients. CONCLUSIONS: The novel panintestinal capsule endoscopy system shows a fair correlation with the Marsh classification in patients with celiac disease. It is also capable of identifying colon polyps. Therefore, the novel panintestinal capsule endoscopy system can be considered for patients with celiac disease and an indication for capsule endoscopy.
