Discharge Summary:

Hospital Course:

The 75-year-old male patient was admitted with elevated serum hepatobiliary enzymes and a history of hypertension, type 2 diabetes mellitus, malignant otitis externa, and an operative history of emergent coronary artery bypass grafting. The results of preoperative laboratory testing showed elevated serum hepatobiliary enzymes, including alkaline phosphatase and gamma glutamic transpeptidase. Imaging tests indicated the presence of a Bismuth type 4, T2N0M0 Stage II hilar cholangiocarcinoma with abrupt narrowing of the common hepatic duct and involvement of the right anterior and posterior bile duct bifurcations. Further investigation confirmed the diagnosis of adenocarcinoma.

Treatment:

The patient underwent left trisectionectomy, extrahepatic bile duct resection, and Roux-en-Y choledochojejunostomy 51 days after undergoing percutaneous balloon arterioplasty followed by bare-metal stent placement to prevent postoperative biliary complications due to the suspected benign stricture caused by atherosclerosis in the right posterior hepatic artery (RPHA).

Clinical Course:

The patient had bile leakage postoperatively, which was successfully controlled through percutaneous drainage. However, he was re-hospitalized with multiple pyogenic liver abscesses 4 months after hepatectomy that eventually led to liver failure. Despite intensive multimodal treatment for the pyogenic liver abscesses, the patient could not be saved.

Disposition:

The patient was discharged from the hospital 3 months after surgery but was re-hospitalized due to complications related to liver abscesses. Unfortunately, he passed away due to liver failure 14 months after surgery.
