Case report: serial percutaneous cholangioscopy with laser ablation for the management of locally recurrent biliary intraductal papillary mucinous tumor.

ABSTRACT

We present a case of serial cholangioscopic laser fulguration of a biliary recurrence of pancreatic intraductal papillary mucinous tumor in a 76-year-old man. Through established percutaneous biliary drain tracts, the aseptic use of a standard 6.9 F ureteroscope and holmium laser fiber facilitated visual ablation within the biliary tree. Quarterly cholangioscopic laser ablation provided safe and effective local control without biliary infectious complications. This case appears to be the first treatment of recurrent intrabiliary intraductal papillary mucinous tumor by serial antegrade choledocoscopy and laser photocoagulation. Effective local control appears possible with minimal morbidity. Standard ureteroscopic equipment facilitates safe and efficient percutaneous antegrade choledocoscopy.
