Long-term survival of over 4 years after microwave tissue coagulation (MTC) therapy via percutaneous transhepatic cholangioscopy in men with jaundice and bile duct carcinoma in the far advanced stage

[Abstract] In this report, we suggest a probable treatment with microwave tissue coagulation (MTC) aimed at curing jaundice and early-stage bile duct carcinoma in elderly patients. Here we report cases of 2 jaundice patients with bile duct carcinoma in the far advanced stage of progression, who survived for more than 4 years after percutaneous transhepatic cholangioscopy (PTCS) and radiography-guided MTC. Long-term survival of over 10 years was achieved in jaundice patients with unresectable bile duct carcinoma and poor health after performing PTCS and radiography-guided MTC. MTC may be an alternative palliative treatment for jaundice patients in the far advanced stage of progression and may afford survival of over 4 years. [Introduction] Our previous reports in which bile duct carcinoma patients with poor physical health were treated by cholangioscopic microwave tissue coagulation (MTC) and survived over 10 years suggest that cholangioscopic MTC is a probable curative treatment for early-stage bile duct carcinoma1)-3).
