title: Repeat hepatectomy for colonic liver metastasis presenting intrabiliary growth--application of percutaneous transhepatic portal vein embolization for impaired liver.
abstract: A 77-year-old man, whose past history included hepatitis C viral infection, transverse colectomy for transverse colon carcinoma, and right hepatectomy for colonic liver metastasis with intrabiliary growth, demonstrated left lateral sectional bile duct dilatation by computed tomography (CT). Percutaneous transhepatic cholangioscopy following percutaneous transhepatic biliary drainage demonstrated a papillary tumor compatible with recurrent liver metastasis presenting with intrabiliary growth. The recurrent tumor extended both into the left lateral inferior (B2) and superior (B3) bile duct branches. Percutaneous transhepatic portal vein embolization (PTPE) of the left lateral sectional branches was performed selectively to enhance the safety of hepatectomy in patients with impaired liver. Expected liver resection volume decreased from 48% to 36% by CT volumetry before and 5 weeks after PTPE. Left lateral sectionectomy was performed without serious postoperative complications. Resected specimen showed a solid tumor measuring 30x25mm and intraluminal tumor extension in B3 and B2. All surgical margins including the bile duct stump were free from carcinoma invasion. The patient survived for 4 years and 5 months postoperatively and died of other causes. An aggressive surgical strategy and PTPE provided significant palliation in this selected patient.
