Preoperative optimization of the liver for resection in patients with hilar cholangiocarcinoma

Optimal preoperative preparation is required to reduce operative risk of major hepatectomy in jaundiced patients. The role of percutaneous preoperative biliary drainage (PTBD) is, apart from assessment of intraductal extent of the tumour, to allow contralateral hypertrophy if portal vein embolization (PVE) is performed. The increased use of PTBD over a 10-year period was associated with increased resectability rate in this study, while PTBD-related complications decreased. Efficient hypertrophy of the future liver remnant (FLR) requires biliary drainage to reduce the risk of postoperative liver dysfunction. Preoperative staging laparoscopy avoided unnecessary surgical exploration in 20% of patients previously considered resectable.
