Intraductal papillary neoplasm of the left hepatic duct treated with endoscopic retrograde cholangiopancreatography guided radiofrequency ablation.

Intraductal papillary neoplasm of the biliary tree (IPNB) is a rare non-invasive neoplasm that carries a high potential for progression to malignancy. Typically, these tumors are managed via surgery with total resection being the fundamental goal. Recently, radiofrequency ablation (RFA) has gained momentum as a treatment option for biliary cancers. Prior studies examining the effect of RFA on biliary tumors usually group all tumor types together, leaving few reports looking at sole outcomes in IPNB. We present an elderly woman with advanced dementia who was admitted with obstructive jaundice secondary to intrahepatic IPNB, and underwent Endoscopic Retrograde Cholangiopancreatography (ERCP) with RFA and stenting resulting in objective improvement in both the size of the lesion and laboratory markers. In the right subset of patients, endobiliary RFA can be used as a safe and effective modality of treatment with minimal complications.
