Endoluminal radiofrequency ablation shows promise for mitigating ingrowth occlusion in biliary tract cancers, indicating a potential solution for obstruction management.
Endoscopic ultrasound-guided hepaticogastrostomy with bridging stent placement is a useful drainage option when endoscopic retrograde cholangiopancreatography fails for reasons such as inaccessible papillae or surgical anastomosis, particularly in patients with malignant hilar biliary obstruction who require bilateral drainage [1] [2]. Recent advances in chemotherapy, such as targeted drugs for specific gene mutations, have improved prognosis in biliary tract cancers [3]. Therefore, the management of recurrent biliary obstruction after stent placement is also an important issue. Endoluminal radiofrequency ablation (RFA) is a novel procedure for biliary diseases and may be an option for treating ingrowth occlusion after metal stent deployment [4] [5].
