A double-blind, randomized, sham-controlled trial of the effect of a radiation-attenuating drape on radiation exposure to endoscopy staff during ERCP
Study investigated whether a radiation-attenuating drape over the fluoroscopy image intensifier reduces radiation exposure during ERCP. Relative risk reduction in radiation was 90%, 91%, and 93% at the three sites. At a high-volume center in which an endoscopist performs 500 therapeutic ERCPs per year, the estimated cumulative annual effective dose is 126 mSv with conventional protection.
