    Aims:

    To evaluate our mean radiation exposure during endoscopic procedures.

    Methods:

    We randomized between september 2017 and june 2018, 255 endoscopic procedures realized under fluoroscopy. 5 experienced endoscopist work in 2 rooms (one with GE system, the other with Siemens system). The Kerma-area product (KAP) was retrospectively evaluated and classified according to the type of procedure.

    Results:

    Our global mean KAP differs between the two rooms (13 vs. 21 Gy-cm2). We independently analyzed the results for each type of procedures: for difficult ERCP procedure the difference persists (14 vs. 27) when the mean KAP was the same in the 2 rooms for bile duct sone removal (12 Gy-cm2). The mean KAP was the same for the two rooms for prosthesis removal (6 Gy-cm2), and evaluated only in room 1 for dilation (7 Gy-cm2), and digestive prosthesis (9 Gy-cm2).

    Conclusions:

    Our mean KAP were globally close to the more recent dose level reference. It differs between two rooms and the difference may be explained by different procedures in the both rooms. Usually the dose level reference are pooling in"therapeutic ERCP" which may induce different results depending on kind of procedures realized in the center. We propose a more precise mean value dose level reference to evaluated (taking into account also a standard situation especially results given for patients of 70 – 75 kg). In our center, this evaluation was done before a training in radiation exposure and will be repeated each year to verify the continuation of optimization.
