Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

By comparing dimethicone administration with/without subsequent repetitive position change before magnetically controlled capsule endoscopy (MCE) examination, the investigators aim to determine the efficacy of repetitive position change in improving gastric cleanliness for MCE examination.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a single-blind, randomized controlled trial. Subjects receiving magnetically controlled capsule endoscopy at the institution will be randomly allocated into positional change group and conventional group before the procedure. Right after ingesting 5 g dimethicone mixed with 100 ml water, subjects in the position change group will be instructed to repeatedly change the body position according to a pre-specified protocol for a period of 15 min: in the order of supine to the left lateral position to prone, left lateral, supine, right lateral, and repeat last four positions twice, each for 1 min; finally supine for 1 min. Thirty and 40 min after dimethicone administration, subjects in both groups will additionally take 200 ml and 800 ml water, respectively, and undergo MCE examination. Gastric cleanliness will be rated by two physicians independently.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Conventional group

Right after ingesting 5 g dimethicone mixed with 100 ml water, subjects in the conventional group will receive no intervention. Thirty and 40 min after dimethicone administration, subjects will additionally take 200 ml and 800 ml water, respectively, and undergo MCE examination.

Group Type NO_INTERVENTION

No interventions assigned to this group

Position change group

Right after ingesting 5 g dimethicone mixed with 100 ml water, subjects in the position change group will be instructed to repeatedly change the body position according to a pre-specified protocol for a period of 15 min: in the order of supine to the left lateral position to prone, left lateral, supine, right lateral, and repeat last four positions twice, each for 1 min; finally supine for 1 min. Thirty and 40 min after dimethicone administration, subjects in both groups will additionally take 200 ml and 800 ml water, respectively before undergoing MCE examination.

Group Type EXPERIMENTAL

Position change group

Intervention Type BEHAVIORAL

Right after ingesting 5 g dimethicone mixed with 100 ml water, subjects in the position change group will be instructed to repeatedly change the body position according to a pre-specified protocol for a period of 15 min: in the order of supine to the left lateral position to prone, left lateral, supine, right lateral, and repeat last four positions twice, each for 1 min; finally supine for 1 min. Thirty and 40 min after dimethicone administration, subjects in both groups will additionally take 200 ml and 800 ml water, respectively before undergoing MCE examination.
