    Resection of hilar cholangiocarcinoma with left hepatectomy after pre-operative embolization of the proper hepatic artery

    HPB, Issue 2 2010
    Yoshikazu Yasuda
    Abstract Background:, Right or right-extended hepatectomy including the caudate lobe is the most common treatment for hilar cholangiocarcinoma (HC). A 5-year survival of up to 60% can be achieved using this procedure if R0-resection is obtained. However, for some patients a left-sided liver resection is necessary to obtain radical resection. The close relationship between the right hepatic artery and the HC in these patients frequently limits the ability to achieve a radial R0-resection without difficult vascular reconstruction. The aim of the present study was to describe the outcome of patients who underwent pre-operative embolization of the proper hepatic artery in an effort to induce development of arterial collaterals thus allowing the resection of the proper and right hepatic artery without vascular reconstruction. Methods:, In patients presenting with HC who were considered to require a left hepatic lobectomy and in whom pre-operative work up revealed possible tumour invasion of the right hepatic artery, transcatheter arterial embolization (TAE) of the proper hepatic artery or the left and right hepatic arteries was performed. Three weeks later, a left-sided hepatectomy with resection of all portal structures except the portal vein was performed. Results:, In six patients, pre-operative embolization of the proper hepatic artery was performed. Almost instantaneously in all six patients arterial flow signals could be detected in the liver using Doppler ultrasonography. No patient died peri-operatively. In all six patients an R0 radial resection was achieved and in three an R0 proximal transection margin was obtained. All post-operative complications were managed successfully using percutaneous drainage procedures. No patient developed local recurrence and two patients remain disease free more than 7 years after surgery. Summary:, After pre-operative embolization of the proper hepatic artery, resection of the HC with left hepatectomy is a promising new approach for these technically demanding patients, giving them the chance of a cure.

    Vertical portal vein clamping in right hepatic lobectomy for live donation or neoplasm

    A modified technique is described in clamping the right branch of the portal vein in right hepatic lobectomy for live donation or neoplasm that allows flush division of the origin of the right branch without causing portal vein stenosis. [source]

    Laparoscopic-Assisted Right Lobe Donor Hepatectomy

    AMERICAN JOURNAL OF TRANSPLANTATION, Issue 10 2006
    A.J. Koffron
    The major impediment to a wider application of living donor hepatectomy, particularly of the right lobe, is its associated morbidity. The recent interest in a minimally invasive approach to liver surgery has raised the possibility of applying these techniques to living donor right lobectomy. Herein, we report the first case of a laparoscopic, hand-assisted living donor right hepatic lobectomy. We describe the technical aspects of the procedure, and discuss the rationale for considering this option. We propose that the procedure, as described, did not increase the operative risks of the procedure; instead, it decreased potential morbidity. We caution that this procedure should only be considered for select donors, and that only surgical teams familiar with both living donor hepatectomy and laparoscopic liver surgery should entertain this possibility.

    Liver regeneration after major hepatectomy for biliary cancer

    BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 8 2001
    Dr M. Nagino
    Background: The aim of this study was to evaluate serial changes in liver volume after major hepatectomy for biliary cancer and to elucidate clinical factors influencing liver regeneration. Methods: , Serial changes in liver volume were determined, using computed tomography, in 81 patients with biliary cancer who underwent right hepatic lobectomy or more extensive liver resection with or without portal vein resection and/or pancreatoduodenectomy. Possible factors influencing liver regeneration were evaluated by univariate and multivariate analyses. Results: The remnant mean(s.d.) liver volume was 41(8) per cent straight after hepatectomy. This increased rapidly to 59(9) per cent within 2 weeks, then increased more slowly, finally reaching a plateau at 74(12) per cent about 1 year after hepatectomy. The regeneration rate within the first 2 weeks was 16(8) cm3/day and was not related to the extent of posthepatectomy liver dysfunction. On multivariate analysis, the extent of liver resection (P < 0·001), body surface area (P = 0·02), combined portal vein resection (P = 0·024) and preoperative portal vein embolization (P = 0·047) were significantly associated with the liver regeneration rate within the first 2 weeks. In addition, body surface area (P < 0·001) and liver function expressed as plasma clearance rate of indocyanine green (P = 0·01) were significant determinants of final liver volume 1 year after hepatectomy. Conclusion: The liver regenerates rapidly in the first 2 weeks after major hepatectomy for biliary cancer. This early regeneration is influenced by four clinical factors. Thereafter, liver regeneration progresses slowly and stops when the liver is three-quarters of its original volume, approximately 6 months to 1 year after hepatectomy. © 2001 British Journal of Surgery Society Ltd [source]
