About this study
Investigators assess the gastric contents by ultrasonography in fasted patients undergoing cholecystectomy.
Read the detailed description
Investigators evaluate the gastric volume through cross sectional area and amount of clear fluid using Perlas grade by ultrasound in the supine and right lateral position of fasted patients undergoing cholecystectomy. Full stomach is regarded if solid gastric contents are detected or clear fluid is more than 1.5 ml/kg. The frequency of full stomach will be analyzed.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Ultrasound assessment of gastric contetOther
Ultrasound assessment of gastric content is performed in fasted patient undergoing cholecystectomy.
| Study group | Role | What they receive |
|---|---|---|
| Fasted patients for cholecyctectomy | The fasted patients for cholecyctectomy except exclusion criteria are included Receives: Other: Ultrasound assessment of gastric contet |
What is being measured
The primary outcome is the main question the study is designed to answer.
Incidence of full stomach
The incidence of full stomach is assessed by using ultrasonography.
Measured: Before the induction of anesthesia
Secondary outcomes (3)
Cross sectional area of the stomach
The cross sectional area of the stomach is assessed by using ultrasonography in the supine and right lateral positions.
Measured: Before the induction of anesthesia
Volume of stomach
The volume of stomach is assessed using the following formula; volume of stomach (mL) = 27.0 + 14.6 x cross-sectional area (right lateral position) - 1.28 x age.
Measured: Before the induction of anesthesia
Type of gastric contents
The type of gastric contents is assessed using ultrasonography.
Measured: Before the induction of anesthesia

The record says: finished, as of the sponsor's last update on 21 May 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Incidence of full stomach (time frame: Before the induction of anesthesia). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03259841, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 May 2019; AzTrials last refreshed its copy on 8 Nov 2026.
