Background: Diagnostic yield of video capsule endoscopy (VCE) may be higher if it is performed closer to the
time of overt obscure GI bleeding (OOGIB).
Objective: To evaluate the diagnostic yield of VCE and rate of therapeutic intervention for OOGIB for inpatients
and outpatients with respect to timing of the intervention.
Design: Retrospective cohort study.
Setting: Tertiary academic center.
Patients: Patients who had VCE for OOGIB between August 2008 and August 2010.
Interventions: VCE for inpatients versus outpatients.
Main Outcome Measures: Diagnostic yield and rate of therapeutic intervention for inpatients versus outpatients.
Results: One hundred forty-four inpatients (65 women) and 116 outpatients (49 women) were included.
Diagnostic yield was 65.9% for inpatients versus 53.4% for outpatients (P = .054). Inpatients were divided into
those who had VCE within 3 days (3 days; n = 90) of admission versus after 3 days (3 days; n = 54). Active
bleeding and/or an angioectasia was found in 44.4% of the 3-day group compared with 27.8% of the 3-day
group (P = .046) versus 25.8% of the outpatients. Therapeutic intervention was performed in 18.9% of the
3-day group versus 7.4% of the 3-day group (P = .046) versus 10.3% of outpatients. Diagnostic yield and
therapeutic intervention rate between the 3-day group and outpatients were not significantly different. Length
of stay (days) was less in the 3-day cohort, at 6.1 versus 10.3 in the 3-day cohort (P .0001).
Limitations: Long-term outcomes were not studied. This was a retrospective study.
Conclusions: Early deployment of VCE within 3 days of admission results in a higher diagnostic yield and
therapeutic intervention rate and an associated reduction of length of stay. ( Gastrointest Endosc 2013;77:761-6.)
