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)
BACKGROUND The role of surgical resection for hepatocellular carcinoma with tumor thrombi involving the major portal vein is controversial because of a high operative risk and poor prognosis. Previously, a resection was performed only when the tumor thrombi were limited to the first branch of the portal vein without extension to the portal bifurcation. (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 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)
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)
BACKGROUND Systemic antibiotics are administered frequently after hepatectomy to prevent infective complications, but their effectiveness is uncertain. METHODS A total of 127 patients with liver tumours were prospectively randomized into two groups after hepatectomy: in group 1 (62 patients) no antibiotics were given until the appearance of infective(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 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 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 Hepatic resection for multiple hepatocellular carcinomas (HCCs) involving both lobes of the liver is rarely recommended because of high operative risks and low radicality. Thus the justification of hepatic resection for bilobar multicentric HCC remains undefined. METHODS Two hundred eleven patients with HCC, who underwent curative hepatic(More)
