BACKGROUND To determine the optimal management of the intraductal papillary mucinous neoplasms (IPMNs) according to the morphologic type based on distinguishing between benign and malignant diseases. BACKGROUNDS IPMNs are increasingly recognized clinicopathologic entity. Extended pancreatic resection with radical lymph node dissection has been recommended(More)
The aim of this study was to evaluate CT and MRI findings in xanthogranulomatous cholecystitis (XGC) and to correlate the imaging findings with various pathologic parameters. The study included 13 patients with histopathologically confirmed XGC. The CT (n=13) and MRI (n=5) obtained in these patients were evaluated retrospectively. On CT, low-attenuation(More)
BACKGROUND/AIMS Hepatocellular carcinoma (HCC) is uncommon in adolescent and young adult Japanese. The aim of this study was to examine the clinicopathological analysis of Japanese young adults with HCC. METHODOLOGY We reviewed the cases of 11 patients with HCC who were between 13 and 40 years of age. RESULTS All patients were HBs antigen-positive(More)
Although the standard operation for early cancer of gastric cardia is proximal gastrectomy followed by jejunal interposition, we recently reported a simple and useful technique for proximal gastrectomy with gastric tube reconstruction. The operative procedures included resection of the proximal two-thirds of the stomach, followed by anastomosis between the(More)
Desmoplastic fibroblastoma (collagenous fibroma) developing as a slowly enlarging lower abdominal mass is described. The lesion had inhomogeneous low signal intensity (SI) on T1-weighted images, and mixed SI as low SI within high SI on T2-weighted images. On post-contrast T1-weighted images, the mass showed inhomogeneous enhancement. Histologically, the(More)
Bile leakage after hepatic resection often results in the formation of a biliary-cutaneous fistula. Such a fistula, when caused by an isolated bile duct in the remnant liver, can be intractable. We report a successful case of ethanol injection therapy of an isolated bile duct. A 73-year-old man underwent right hepatic resection for hepatocellular carcinoma.(More)
BACKGROUND/AIMS Although microwave coagulation therapy (MCT) has been performed for liver cancer, there has been no report examining the influence of this therapy on the growth of possible remnant cancer. METHODS A solid cube of AH-130 cells (ascites hepatoma cell line) was implanted into the left lateral lobe of the rat liver. Five days later, MCT was(More)
Background/aims. To evaluate the safety and feasibility of immunotherapy based on autologous dendritic cells (DC) for patients with unresectable primary liver cancer (PLC). Methods. A total of ten patients were enrolled and immunized with DCs. Autologous DCs were generated ex vivo in the presence of granulocyte-macrophage colony-stimulating factor (GM-CSF)(More)
BACKGROUND/AIMS Surgical resection is not always feasible for patients with hepatocellular carcinoma. We used microwave coagulation therapy (MCT) as an alternative to resection and evaluated its efficacy. METHODOLOGY Twenty-four patients with unresectable hepatocellular carcinoma underwent microwave coagulation therapy by laparotomy (n=18), laparoscopy(More)
PURPOSE Pancreatic cancer has a poor prognosis and few effective therapies are available. The oncolytic effect of reovirus has been observed in cancer cells with an activated Ras signaling pathway, and pancreatic cancer may be a candidate target for reovirus because K-ras mutation is frequently found in pancreatic cancer. EXPERIMENTAL DESIGN In this(More)
