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

LIVER TRANSPLANTATION, Issue 6 2002
Katsuhiko Yanaga MD
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]
