In a prospective study following a validated training module, we found that a selected group of endoscopists identified rectosigmoid neoplastic lesions with pooled NPVs greater than 90% and accurately selected surveillance intervals for more than 90% of patients over the course of 1 year. Providing regular interim feedback on the accuracy of neoplastic lesion prediction and surveillance interval selection did not lead to differences in those endpoints. Monitoring is suggested, as individual performance varied. ClinicalTrials.gov no: NCT02516748; Netherland Trial Register: NTR4635.

We aimed to assess technical feasibility, clinical applicability, and diagnostic yield of videocapsule endoscopy (VCE) in a large group of unselected patients. VCE was performed with the Given Imaging swallowable capsule. Findings were considered diagnostic if the observed finding could explain the symptomatology of the patient. Findings were considered suspicious if an observed finding failed to completely explain the patient's symptoms. We studied 250 patients. A definite diagnosis was made in 95 patients (38%). Suspicious findings were noted in 80 patients (32%). No diagnosis was obtained in 74 patients (30%). The yield of VCE was higher in patients with suspected Crohn's disease. Mean viewing time decreased significantly from 51 +/- 14 to 30 +/- 7 minutes after reviewing 50 procedures. VCE is an important diagnostic tool, but a definite diagnosis is established in only 38% of the patients. The highest diagnostic yield is obtained in patients with suspected Crohn's disease.
