Objectives:
To assess the safety and feasibility and discuss the oncological impact of a portal vein resection using the no-touch technique with a hepatectomy for locally advanced hilar cholangiocarcinoma.
Patients And Methods:
From 2005 to March 2009, 49 patients with hilar cholangiocarcinoma underwent a major right-sided hepatectomy with curative intent. Portal vein resection was performed using the no-touch technique in 36 patients (PVR group) but the portal vein was not resected in the other 13 patients (NR group). Peri-operative data and histological findings were compared between the two groups. Moreover, tumour recurrence and survival rates after surgery were calculated and compared for each group.
Results:
Although the tumours of the patients in the PVR group were more locally advanced, the residual tumour status and tumour recurrence rate were similar and there was no significant difference in long-term survival between the two groups: 5-year survival rates in the PVR and NR groups were 59% and 51%, respectively (P = 0.353). In-hospital mortality was encountered in 2 of the 49 patients.
Conclusion:
A portal vein resection using the no-touch technique with a right-sided hepatectomy had a positive impact on survival and is feasible in terms of long-term outcomes with acceptable mortality.
