Repetitive Position Change Improves Gastric Cleanliness for MCE

3. juli 2019 opdateret af: Zhuan Liao, Changhai Hospital

Repetitive Position Change After Dimethicone Premedication Improves Gastric Cleanliness for Magnetically Controlled Capsule Endoscopy: a Single-blind, Randomized Controlled Trial

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.

Detaljeret beskrivelse

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.

Intervention / Behandling
Ingen indgriben: 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.
Eksperimentel: 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.

Tidsramme
Image Cleanliness of Gastric Cavity
Tidsramme: 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)

Tidsramme
The Type of Positive Findings Detected by Magnetically Controlled Capsule Gastroscopy
Tidsramme: 30 minutes
Positive findings defined as any pathology detected by Magnetically controlled capsule gastroscopy (MCCG), including polyps, ulcer, gastric fundus varices, submucosal tumor, and carditis.
30 minutes
Number of Participants With Adverse Events
Tidsramme: 2 weeks
Safety of MCCG, or adverse events, defined as symptoms or signs such as abdominal distention, nausea, or vomiting, were monitored closely during the MCCG 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.
