NCT02791659

Brief Summary

X-ray beam produced during endoscopic retrograde cholangiopancreatography (ERCP) affect not only the patient, but the personnel of ERCP team may have the effect from the scattered ray. According to the automatic beam adjustment function, the thicker object (eg. lying left lateral) might produce higher scatter ray than thinner object (eg. lying prone). The investigators evaluate the radiation exposure among ERCP personnel compare between patient's 2 different positions.

Outcome Measures

Primary Outcomes (1)

  • Effective Radiation Dose

    The effective radiation which represents equivalent dose to eye lens of each personnel were compared between 2 groups.

    Immediate after procedure

Study Arms (2)

Left lateral decubitus

ACTIVE COMPARATOR

In this group, the position will be assigned to Left lateral decubitus during ERCP. The radiation from fluoroscopy will be adjusted by automatic beam adjustment function to obtain the image quality.

Radiation: Automatic beam adjustment function

Prone

EXPERIMENTAL

In this group, the position will be assigned to Prone during ERCP. The radiation from fluoroscopy will be adjusted by automatic beam adjustment function to obtain the image quality.

Radiation: Automatic beam adjustment function

Interventions

The fluoroscopy system has an automatic beam adjustment function to maintain a good quality of image output.
