[Edwardsiella tarda Bacteremia in the Setting of Recurrence at the Hepatic Hilum after Surgery for Lower Bile Duct Cancer-A Case Report].

The patient was a 70s-years-old male. Subtotal stomach-preserving pancreaticoduodenectomy and Child modified reconstruction was performed for lower bile duct cancer. Seven months after surgery, the patient developed pulmonary metastasis recurrence, and 9 months after surgery, the soft tissue shadow at the hepatic hilum had increased and portal vein obstruction had occurred, so best supportive care was adopted. Diarrhea began at the 10 months after surgery. 13 months after surgery, the patient was hospitalized with respiratory dysfunction due to malignant pleural effusion. One week after admission, the patient exhibited liver dysfunction and a high fever of 41.0℃; blood cultures were submitted and MEPM/ VCM was initiated, after which the fever subsided tomorrow. Edwardsiella tarda (E. tarda) was detected in the blood culture results obtained 2 days later, and based on the clinical symptoms, the patient was diagnosed with bacteremia resulting from cholangitis due to E. tarda. If recurrence occurs in the hepatic hilum after pancreaticoduodenectomy, intestinal fluid reflux is likely to occur, leading to cholangitis due to E. tarda, and bacteremia can be fatal, so this should be kept in mind as an oncology emergency.
