Abstract
Endoscopic microwave coagulation therapy (EMCT) was applied to three patients (bile duct cancer: 2 cases, pancreas cancer: 1 case) with re-obstructive jaundice after expandable metallic stent (EMS) therapy due to unresectable malignant biliary obstruction. Bile duct re-endoprosthesis was difficult after EMS therapy and the period of patency after re-endoprosthesis was short about 2-3 months, EMCT was carried out for local control. One patient is alive for 20 months and obstructive jaundice has not been occurred for 11 months after EMCT, and other 2 patients died 7 months, 5 months later after EMCT by liver metastasis and peritoneal dissemination but patency was reserved. Endoprosthesis was performed by EMCT with safe and this therapy was an effective therapy for patients with re-obstructive jaundice after EMS.
