Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Stomach Diseases Behavioral: Position change group Not Applicable

Detailed Description:
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.

Arm Intervention/treatment
No Intervention: 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.
Experimental: 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.
Behavioral: 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.




Primary Outcome Measures :
  1. Image cleanliness of gastric cavity [ Time Frame: 30 minutes ]
    The image cleanliness of gastric cavity of six primary anatomical landmarks of stomach (cardia, fundus, body, angulus, antrum, and pylorus) were recorded for evaluation. A 4-point grading scale was introduced to define the cleanliness as excellent (no adherent mucus and foam: score 4), good (mild mucus and foam but does not obscure vision: score 3), fair (considerable amount of mucus or foam present precluding a completely reliable examination: score 2) and poor (large amount of mucus or foam residue needing water to clear it: score 1)


Secondary Outcome Measures :
  1. Positive findings of MCE [ Time Frame: 30 minutes ]
    Positive findings defined as any pathology detected by MCE.

  2. Safety outcomes and adverse events [ Time Frame: 2 weeks ]
    Safety of MCE, or adverse events, defined as symptoms or signs such as abdominal distention, nausea, or vomiting, were monitored closely during the MCE procedure. Capsule retention (i.e., a capsule endoscope remaining in the gastrointestinal tract for more than two weeks or a capsule endoscope that requires directed intervention or therapy to aid its expulsion) was monitored and followed up for up to two weeks.
