A prospective evaluation of radiation-free direct solitary cholangioscopy for the management of choledocholithiasis.

Background And Aims: Endoscopy has replaced many radiologic studies for the GI tract. However, ERCP remains a hybrid endoscopic-fluoroscopic procedure, which limits its portable delivery, creates delays because of fluoroscopy room unavailability, and exposes patients and providers to radiation. We evaluated fluoroscopy/radiation-free management of patients with noncomplex choledocholithiasis using direct solitary cholangioscopy (DSC).

Liver transplant-related anastomotic biliary strictures: a novel, rapid, safe, radiation-sparing, and cost-effective management approach.

Background And Aims: Biliary strictures after orthotopic liver transplantation (OLT) are typically managed by sequential ERCP procedures, with incremental dilation of the stricture and stent exchange (IDSE) and placement of new stents. This approach resolves >80% of strictures after 12 months but requires costly, lengthy ERCPs with significant patient radiation exposure. Increasing awareness of the harmful effects of radiation, escalating healthcare costs, and decreasing reimbursement for procedures mandate maximal efficiency in performing ERCP.
