Abstract

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.

DESIGN:

Randomized prospective study.

SETTING:

Third-level hospital.

PATIENTS:

Consecutive outpatients in whom VCE was indicated. Exclusion criteria were inpatients and previous gastric surgery.

INTERVENTION:

GTT for RLP 30 minutes after swallowing the capsule versus non-RLP (standing up position).

MAIN OUTCOME MEASUREMENTS:

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.

LIMITATION:

Only outpatients were included.

CONCLUSIONS:

RLP after swallowing the capsule does not influence either GTT nor the rate of VCE complete procedures.
