Incremental yield of dysplasia detection in Barrett's esophagus using volumetric laser endomicroscopy with and without laser marking compared with a standardized random biopsy protocol.

Background And Aims: Volumetric laser endomicroscopy (VLE) is a new wide-field advanced imaging technology for Barrett's esophagus (BE). No data exist on incremental yield of dysplasia detection. Our aim is to report the incremental yield of dysplasia detection in BE using VLE.

Comparison of the diagnostic yield and outcomes between standard 8 h capsule endoscopy and the new 12 h capsule endoscopy for investigating small bowel pathology.

Aim: To evaluate the completion rate and diagnostic yield of the PillCam SB2-ex in comparison to the PillCam SB2.

Methods: Two hundred cases using the 8-h PillCam SB2 were retrospectively compared to 200 cases using the 12 h PillCam SB2-ex at a tertiary academic center. Endoscopically placed capsules were excluded from the study.

CT enterography vs. capsule endoscopy.

Small bowel imaging has been revolutionized by CT enterography and capsule endoscopy. We present an overview of both imaging modalities, discuss advantages and disadvantages of each, and compare findings in Crohn's disease, occult gastrointestinal bleeding, and small bowel tumors. Both methods complement each other often providing information that the other one cannot.
