Study population: Any indications for undergoing an ERCP. If a patient undergoes more than one ERCP then it shall be reported as such, as multiple data points. Only those ERCP cases will be included that have been exposed to fluoroscopy (X-ray radiation). Those in whom the biliary or pancreatic ducts are not cannulated and therefore who do not receive any fluoroscopy will be excluded. Adult populations will be included, all races and belonging to any gender will be included in the study.

What is being measured
The primary outcome is the main question the study is designed to answer.
Radiation exposure as assessed by fluoroscopy time
Radiation exposure of patients who undergo ERCP (Endoscopic Retrograde Cholangio Pancreatography) will be assessed by fluoroscopy time, which is indicated by the device used for ERCP. Fluoroscopy time at the time of ERCP will be recorded at the end of the procedure and is documented by the endoscopy technician.
Measured: at the time of ERCP
Radiation exposure as assessed by total emittance
Radiation exposure of patients who undergo ERCP (Endoscopic Retrograde Cholangio Pancreatography) will be assessed by total emittance, which is indicated by the device used for ERCP. Total emittance at the time of ERCP will be recorded at the end of the procedure and is documented by the endoscopy technician.
Measured: at the time of ERCP

Questions about this trial
What is this clinical trial studying?
An observational study of Pancreatic Cancer, run by The University of Texas Health Science Center, Houston at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 12 Jan 2021. 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 United States. 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Prithvi Patil, MS ((713) 500-6654, prithvi.b.patil@uth.tmc.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Radiation exposure as assessed by fluoroscopy time (time frame: at the time of ERCP). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 12 Jan 2021; AzTrials last refreshed its copy on 8 Nov 2026.
