Radiation exposure may put endoscopists at risk when performing endoscopic retrograde cholangiopancreatography. Although non-radiation endoscopic retrograde cholangiopancreatography was reported in pregnant women in previous reports, it remains unclear whether endoscopic retrograde cholangiopancreatography is also effective and safe when endoscopists were not expose to radiation. This study was to evaluate the effectiveness and safety of nonradiation-to-endoscopist endoscopic retrograde cholangiopancreatography in patients with complexity level I/II.

Enrollment
219
All patients received magnetic resonance cholangiopancreatography before the procedure. Characteristics of lesions (e.g. common bile duct stones, stenosis) in detail was identified. During the procedure, the endoscopist was not exposed to radiation. If fluoroscopy was needed, after contrast injection (sometimes not necessary), the endoscopist went outside of the operation room and observed the X-ray image by remote control of the fluoroscopy machine.
Patients received standard endoscopic retrograde cholangiopancreatography. Fluoroscopy was normally used when necessary.

Success of endoscopic retrograde cholangiopancreatography
The success is defined by complete removal of common bile duct stones or placement of stents in proper position.
Time frame: 6 months
Overall complications
Post-endoscopic retrograde cholangiopancreatography pancreatitis, bleeding, perforation, infection of biliary tract
Time frame: 6 months
Cannulation success rate
In patients with native papilla, cannulation success rate was defined as the proportion of subjects with successful cannulation of targeted duct
Time frame: 6 months
ERCP procedure time
defined by the interval time between scope insertion and complete of endoscopic retrograde cholangiopancreatography
Time frame: 6 months
