Cholangioscopy assisted guidewire placements can be technically successful, especially in cases where conventional ERCP guidewire placement previously failed.¹

​This technique may also help to avoid more invasive procedures such as percutaneous transhepatic management or endoscopic ultrasound-guided biliary drainage.¹

Experience at the University Hospital of Münster1,2

A retrospective study1…​

…analyzed 167 cholangioscopy procedures for successful guidewire placements across biliary strictures. Only cases with previous failed conventional guidewire placement approaches were included. ​

30 cases performed in 23 patients were identified: ​

  • ​Post-liver-transplant strictures were the most frequent finding among benign patients (52%) 
  • Guidewire placement was successful in 21 of 30 procedures (70%)​
  • Guidewire placements were significantly more successful in patients with benign strictures    ​

A prospective trial2

 …evaluated the benefit of cholangioscopy following fluoroscopy-guided ERCP for management of biliary complications after liver transplantation in a cohort of 26 patients.

Benefits of cholangioscopy over ERCP were found in 12 of 26 (46,2%) patients: 

  • Four successful selective guidewire placements where ERCP attempts had failed
  • Three biliary cast and six stones cases not diagnosed by ERCP
  • One bile duct ulcer due to fungal infection and one case of inflammation in the bile duct caused by acute cholangitis
