The objective of this study were to evaluate the efficacy of hepatic resection for large hepatocellular carcinomas (HCCs) and examine clinicopathologic factors influencing overall survival after resection of a large HCC. The pre-, intra-, and postoperative factors and long-term outcome of 26 patients with HCCs >10 cm who underwent hepatic resection (group(More)
Hepatectomy with vascular reconstruction for biliary malignancy remains controversial. This study aimed to clarify the indications for surgery. Patients with advanced hilar bile duct cancer (HBDC) (n = 26) and gallbladder cancer (GBC) involving the hepatoduodenal ligament (n = 13) who underwent hepatectomy were enrolled. They were divided into two groups on(More)
Although liver resection offers the only realistic chance of cure for patients with liver metastases from colorectal cancer, no consensus exists as to the procedure of choice for managing these tumors. Data from 193 patients who underwent hepatectomy for liver metastases from colorectal cancer and 26 of 193 patients who underwent repeat hepatectomy for(More)
We determined the relative value of the metastatic colorectal cancer doubling time as a predictor of recurrence and survival after hepatectomy in comparison with other established predictors. Consecutive patients who underwent hepatic resection (n = 144) for colorectal cancer liver metastases were studied retrospectively to identify factors that influence(More)
Prostaglandin E1 (PGE1) has several potential therapeutic effects, including cytoprotection, vasodilation, and inhibition of platelet aggregation. This study investigates the protective action of PGE1 against hepatic ischemia/reperfusion injury in vivo using a complementary DNA microarray. PGE1 or saline was continuously administered intravenously to mice(More)
The objective of this study was to evaluate the effectiveness and feasibility of using the Cavitron ultrasonic surgical aspirator (CUSA) with argon beam coagulation (ABC) during hepatic resection, in comparison with a conventional method using CUSA with bipolar cautery. Between April 2003 and March 2004, a series of 14 consecutive patients underwent hepatic(More)
The safe and permissible limits of hepatectomy in obstructive jaundice patients and the usefulness of preoperative portal embolization (PE) for increasing the limit for safe hepatectomy were examined. We classified 416 patients with hepatectomy performed over 9 years under the following headings: normal liver function (n = 242); chronic hepatitis (n = 71);(More)
Division of the splenic vein was performed in 29 patients who underwent pancreatoduodenectomy to achieve lymph node dissection and neural resection around the superior mesenteric artery. The basic protocol for the splenic vein reconstruction to reduce congestion of the spleen and stomach is as follows. When the inferior mesenteric vein (IMV) drained into(More)
The aim of this study was to identify the perioperative risk factors for postoperative bile leakage after hepatic resection and to propose a treatment strategy for such leakage when it does occur. Between 1992 and 2000 a total of 313 hepatic resections without choledocojejunal anastomosis were performed at our institute. Risk factors related to bile leakage(More)
