Cirrhosis is associated with blood loss during liver resection and postoperative complications. The liver stiffness measurement has recently become available for assessment of liver fibrosis.This prospective study was performed to predict postoperative outcomes of liver resection. The liver stiffness measurement was measured prospectively using magnetic resonance elastography for patients who had...
Incidental detection of nonenhancing tumors during imaging studies for patients with classical hepatocellular carcinoma is not unusual. These tumors are considered to have a high potential of malignant transformation. The aim of this study was to clarify the natural history of such tumors.In 93 patients who underwent liver resection for hepatocellular carcinoma, 138 nonenhancing or enhancing nodules...
Although MRI has been considered one of the most sensitive diagnostic techniques for hepatocellular carcinoma (HCC), a clear-cut beneficial effect of the use of preoperative MRI remains unclear. We assessed whether preoperative MRI has a beneficial effect on outcomes in patients scheduled to undergo resection of HCC.We evaluated 449 patients with 553 liver tumors. MRI was performed in 349 of these...
Surgeons have attempted to prevent early cancer-related death after resection of hepatocellular carcinoma to identify risk factors associated with early death from hepatocellular carcinoma recurrence after liver resection.The study group comprised 350 patients who had undergone liver resection for hepatocellular carcinoma between 1997 and 2007. The preoperative risk factors for early death from intrahepatic...
The surgical outcome of middle and/or distal bile duct cancer remains unsatisfactory. Although the resectional margin is known to be a predictive factor, the prognostic significance of a positive ductal margin and other radial margin has never been evaluated independently.The clinicopathologic data of 55 patients who had undergone surgical resection for middle and/or distal bile duct cancer between...
Background. Controversy exists as to whether selective biliary drainage (SBD) or total biliary drainage (TBD) is preferable as a preoperative procedure before extended hemihepatectomy for hilar cholangiocarcinoma, especially with regard to the functional reserve of the future remnant liver. Methods. SBD or TBD was performed after 1 week of total biliary obstruction in rats. In SBD, the biliary trees...
Background: In living related liver transplantation (LRLT), reconstruction of the hepatic vein (HV) by end-to-end anastomosis has been reported to be associated with acute or late outflow block. Methods: We reviewed 42 patients who underwent LRLT from January 1996 to September 1998. Results: In 7 (27%) of the 26 donor grafts obtained from left lateral segmentectomy or extended lateral segmentectomy...
Background: Although hepatic resection is the most reliable treatment for hepatocellular carcinoma, impaired liver function because of cirrhosis or chronic hepatitis contributes to relatively high rates of postoperative complications. We have reviewed a series of hepatectomies at our institution and investigated risk factors for complications after hepatectomy in patients with impaired liver compared...
