About this study

Official title: Success of Routine Intraoperative Cholangiography

The purpose of the present study was to evaluate the success of routine use of intraoperative cholangiography (IOC ) and to examine the factors that are hindering the performance of intraoperative c-arm cholangiography.

Read the detailed description

From January 2018 to August 2018 all consecutive elective and emergency cholecystectomies performed were entered in a prospective database. IOC has been instructed to be performed routinely when feasible during cholecystectomy since 1998. All elective operations were performed either by residents or specialist surgeons. For this study the investigators collected the radiation exposure values from exposure and pulsed fluoroscopy. Fluoroscopy time (s) was recorded.The operating surgeon was asked to fulfill a questionnaire directly after the cholecystectomy. The technical success and reasons for possible deferral of IOC were documented.Patient data from unsuccessful or deferred cholangiography cases was checked 6 months after cholecystectomy for possible symptomatic residual choledocholithiasis.Laparoscopic cholecystectomies were performed both by residents and specialist surgeons.

Ethics: The study was approved by the hospital administration.

Where is the study taking place?

The record lists 1 site in Finland. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

number of intraoperative cholangiography (time frame: 6 months). 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 NCT04052633, which also lists 7 linked publications.

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 Aug 2019.
