Study summary

The goal of this prospective cohort observational study is to compare incidence of cholangitis cause by multi-drug resistant pathogens in patient who underwent ERCP.

The main question it aims to answer are:

  • Is the single use disposable elevator cap duodenoscope more effective in preventing cholangitis caused by MDR than fixed cap duodeoscope?
  • Is the single use disposable elevator cap duodenoscope more effective in preventing severe cholangitis than fixed cap duodenoscope?

Participants will undergo and ERCP procedure. Among the patients who received the procedure, those who developed cholangitis after procedure will treated with antibiotics after blood culture test. The result of the post procedure cholangitis group's blood culture test and lab data including LFT will be collected. Researches will compare single use disposable elevator cap duodenoscope group and fixed distal cap duodenoscope group to see if there is difference in the incidence of cholangitis caused by MDR pathogens.

Read the detailed description

Insufficient disinfection of duodenoscopes, particularly the elevator site, can cause ERCP-related infections and serve as a significant source of multidrug-resistant (MDR) infection. To address this issue, a disposable elevator cap (DEC) was developed, and a recent randomized clinical trial demonstrated its effectiveness in reducing contamination following high-level disinfection. However, there is limited evidence in actual clinical practice to reduce cholangitis caused by MDR pathogens. This study aimed to compare the efficacy of the novel DEC duodenoscope with the standard duodenoscope in preventing infection transmission.

We conducted a prospective non-randomized cohort study in a single institution comparing baseline characteristics, technical performance, and incidence of acute cholangitis, including MDR pathogen, in 95 patients using a standard duodenoscope and 101 patients using a DEC duodenoscope.

Age, sex, comorbidities, and indication for ERCP were similar between the two groups. However, the standard duodenoscope group had a higher proportion of naïve papilla (51% vs. 34%, p = 0.04), while the technical success rate was slightly higher in the DEC duodenoscope group (95% vs. 85%, p = 0.15). The rates of procedure-related adverse events were similar between the two groups (16% for DEC vs. 15% for standard). The incidence of post-ERCP cholangitis was also similar (10% for DEC vs. 11% for standard, p = 0.90). The proportion of post-ERCP cholangitis caused by MDR pathogens was similar in the two groups (1% for DEC vs. 2% for standard, p = 0.39).

This study suggests that the technical performance of the DEC duodenoscope is similar to that of the standard duodenoscope. However, more clinical data are needed to confirm the efficacy of the DEC duodenoscope in preventing ERCP-related infection transmission.

ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Apr 2023 (actual). Primary completion is estimated for Feb 2024, 9 months after the start.

Of 30 observational studies under Cholangitis, half reached primary completion within 30 months of starting (the median), counting those still running; a quarter within 21 and three quarters within 60. This study's planned 9 months is below that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 3, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
