Case 1 was a 64-year-old man who suffered from choledochoduodenal fistula (CDF) after endoscopic placement of a self-expandable metallic stent (SEMS) for biliary tract obstruction caused by advanced duodenal cancer Stage Ⅳ (T4, N3, M1). Case 2 was a 68-year-old man who suffered from CDF similar to case 1 after endoscopic placement of a SEMS for biliary tract obstruction caused by advanced pancreatic head cancer cStage Ⅳb (T3N2M1). Thereafter, the two patients developed duodenal stenosis of the superior duodenal angle or the second portion, respectively, by tumor invasion. We performed endoscopic duodenal SEMS placement in these 2 cases. These procedures were successful and we could assure safety without short- and long-term occurrences of accidental symptoms. It is important to select a treatment procedure appropriate for the general state and prognosis of the patient and an optimal duodenal stent.
