Endoscopic Biliary Drainage Using Guidewire Cannulation in a Case with Severe Duodenal Stenosis Caused by Duodenal Undifferentiated Carcinoma

摘要

We present a case of duodenal carcinoma, 12 cm in size, with severe stenosis at the second portion of the duodenum. When the patient developed obstructive jaundice, it was impossible to perform endoscopic biliary drainage by standard cannulation due to the stenosis, but was succeeded by wire-guided cannulation using papillotome. Histology of the tumor showed undifferentiated carcinoma without differentiation to any specific cell type. Systemic chemotherapy was started with 5-FU, leucovorin and oxaliplatin. Biliary stent worked well until the patient succumbed three months after. Herein we demonstrate the new advantage of wire-guided cannulation in case of duodenal stenosis.
