Right lateral position does not affect gastric transit times of video capsule endoscopy: a prospective study.

Background: Video capsule endoscopy (VCE) examination of the small bowel is not complete in approximately 20% of the procedures. This fact limits its diagnostic yield. One of the main factors that influences the small-bowel transit time (SBTT) is the gastric transit time (GTT), ie, the interval in which the capsule stays in the stomach. It has been described that placing the patient in a right lateral position (RLP) after swallowing the capsule could decrease the GTT.

Objective: To investigate whether the RLP, after the patient swallows the capsule, shortens the GTT and, secondarily, increases the rate of complete procedures.

Methods: Randomized prospective study. Methods: Third-level hospital. Methods: Consecutive outpatients in whom VCE was indicated. Exclusion criteria were inpatients and previous gastric surgery. Methods: GTT for RLP 30 minutes after swallowing the capsule versus non-RLP (standing up position). Methods: The GTT, SBTT, and rate of complete procedures (examination of the entire small bowel).

Results: We did not observe significant differences in the GTT, the SBTT, and the complete procedures between groups.

Conclusions: Only outpatients were included. Conclusions: RLP after swallowing the capsule does not influence either GTT nor the rate of VCE complete procedures.
