Abstract
Background and study aims We present the first clinical results of a new tandem technique for direct peroral cholangioscopy using a standard ultraslim upper gastrointestinal endoscope and a guide probe that was originally developed for the non-transendoscopic placement of biliary endoprostheses (guide probe of Kautz; MTW, Wesel, Germany).
Patients and methods Twenty direct peroral cholangioscopy procedures were performed with the new anchor-assisted method using the guide probe of Kautz in a single center and were retrospectively analyzed.
Results Indications for anchor-assisted cholangioscopy procedures included indeterminate bile duct strictures (n = 14), filling defects that remained after stone extraction (n = 4), and complex stone extractions (n = 2). Biliary access and visualization of the target region were achieved in 18/20 procedures (90 %). The interventional success rate was 85 % (11 /13 interventions). One case of postinterventional cholangitis occurred (5 %), along with one case of minor peri-interventional papillary bleeding (5 %).
Conclusions The anchor-assisted cholangioscopy technique is feasible and safe for direct cholangioscopy and provides reliable success rates in clinical practice. This technique represents an alternative approach for direct cholangioscopy on a single-operator basis using standard endoscopes.
