Brief summary
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.
Interventions
RADIATIONnonradiation-to-endoscopist endoscopic retrograde cholangiopancreatography
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.
RADIATIONstandard endoscopic retrograde cholangiopancreatography
Patients received standard endoscopic retrograde cholangiopancreatography. Fluoroscopy was normally used when necessary.

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