title: Identification of the duodenal papilla by colon capsule endoscope.
abstract: The sensitivity of small-bowel capsule endoscopy in visualizing a single finding present in everyone, the duodenal papilla, is limited. In this retrospective case series study we evaluated whether the duodenal papilla can be better visualized by a capsule endoscope equipped with cameras on both ends. The recordings of 45 colonic capsule endoscopies (PillCam Colon) performed in a single tertiary center were re-evaluated seeking for the duodenal papilla. The two-hour sleeping period of the colon capsule endoscopy system led to the imaging of duodenum in 10 / 45 patients. The duodenal papilla was identified in 6 / 10 (60 %) patients while the number of frames where the papilla was clearly visualized ranged from 2 - 9. Consequently, a small-bowel capsule endoscope containing two cameras could better identify the duodenal papilla and theoretically other obscure areas of the small bowel, expanding its diagnostic accuracy.
