BACKGROUND Liver resection is risky in patients aged > or = 80 years. Because of short life expectancies and improved nonoperative modalities, the role of liver resection in octogenarians with hepatocellular carcinoma (HCC) is unclear. METHODS A retrospective review of the operative results of 260 patients with HCC between 1991 and 1997 was performed.(More)
BACKGROUND For centrally located hepatocellular carcinoma (HCC), extended major hepatectomy is usually recommended, but the risk of postoperative liver failure is high when liver function is not sound. Mesohepatectomy (en bloc resection of Goldsmith and Woodburne's left medial and right anterior segments or Couinaud's segments IV, V, and VIII) is a rare(More)
BACKGROUND Resection for hepatocellular carcinoma in patients with cirrhosis and impaired liver function is usually unjustified because of higher surgical risks and poorer long-term prognosis. METHODS A retrospective comparison of the background and resectional results of patients with cirrhosis and hepatocellular carcinoma was carried out between those(More)
BACKGROUND Hepatitis B and C viruses are the main causative agents of hepatocellular carcinoma (HCC). The influence of hepatitis viral status on liver resection for HCC remains undetermined. METHODS Patients who underwent curative resection for HCC were divided into four groups: group 1, seronegative for hepatitis B surface antigen (HBsAg) and(More)
BACKGROUND Radical gastrectomy with systematic lymphadenectomy (RG) remains controversial in the treatment of gastric carcinoma. On the other hand, the prognosis of gastric carcinoma, in the presence of intraperitoneal free cancer cells, is poor. The optimal surgical strategy for serosa-involved gastric carcinoma with intraperitoneal free cancer cells(More)
BACKGROUND Liver resection in a patient with cirrhosis carries increased risk. The purposes of this study were to review the results of cirrhotic liver resection in the past decade and to propose safe strategies for cirrhotic liver resection. METHODS Based on the date of operation, 359 cirrhotic liver resections in 329 patients were divided into two(More)
BACKGROUND The need for blood transfusion in cirrhotic liver resection is difficult to determine because of inaccurate estimation of operative blood loss. Moreover, blood transfusion is detrimental to cirrhotic patients. OBJECTIVE To investigate the predictors and limitations of hepatectomy without blood transfusion for cirrhotic patients. DESIGN(More)
BACKGROUND AND OBJECTIVES Surgical resection remains the main option for curing hepatocellular carcinoma (HCC). However, liver resection in patients with end-stage renal disease (ESRD) is risky. The aim of this study is to clarify the role of liver resection for treating HCC in patients with ESRD. METHODS A retrospective review was carried out on 468(More)
BACKGROUND/AIMS Partial or total disruption of pancreaticojejunostomy (PJ) is a rare but serious complication after pancreaticoduodenectomy (PD). The recommended option of treatment is completion pancreatectomy. However, the mortality remains high as most patients were too critical to withstand the procedure. PATIENTS AND METHODS 12 consecutive patients(More)
In this work, we developed a highly memory-efficient, accurate table model that is 10X+ faster than its analytical counterparts: BSIN3/4 models. Speed derives from linear interpolation; accuracy and memory efficiency result from the unstructured grid founded on a BSP tree for discretizing the device function space. We also describe a methodology invoked(More)
