Title: Location of ERCP Impacts Fluoroscopy Time: A Multi-Institutional Retrospective Study
at Tertiary Academic Centers
Version: 1 Date: 02 Jun 2024
Reviewer's report:
This study is a report of a relatively large sample size for exposure to ERCP.
The theme of the difference of radiation exposure  whether fluoroscopic manipulation is
performed by an endoscopist or a radiology technician, and whether the fluoroscopy is
performed after hours or not.
#1. Fluoroscopic procedures such as ERCP vary greatly between diagnosis and treatment.
Especially in treatment,  the difficulty differ depending on the purpose of treatment, so it is
difficult to make comparisons without the background of such procedures. As mentioned in
the Limitation section of the Discussion, in urgent cases or out-of-hours situations, it is often
necessary to minimize the procedures to a minimum, such as drainage only.
It would be very interesting to see the results of the study that there was a difference in the results
of EU, RS, and OR, though, it is difficult to conclude from this results that there is a difference
in fluoroscopy time between endoscopists or technicians.
#2. The term "Multi-Institutional" is mentioned, but the breakdown of multi-institutional should
be indicated.
Method section line, only the setup of one institution is described.
"ERCPs in the EU were performed with Siemens Luminos Agile fluoroscopy device, in the RS
with Shimadzu G4 Sonial vision fluoroscopy device, and in the OR with GE OEC Elite C-Arm
device."
