BACKGROUND Portal venous thrombosis (PVT) is a potentially fatal complication following splenectomy. Its mechanisms and risk factors are poorly understood, especially in patients with cirrhosis and portal hypertension. This study investigated risk factors for PVT following splenectomy in such patients. METHODS All consecutive patients with cirrhosis who(More)
Vascular endothelial growth factor (VEGF) plays an essential role in the initiation and regulation of angiogenesis-a crucial component of wound healing and cancer growth. Prostaglandins (PGs) stimulate angiogenesis but the precise mechanisms of their pro-angiogenic actions remain unexplained. We investigated whether prostaglandin E(2) (PGE(2)) can induce(More)
BACKGROUND/AIM Combined hepatocellular-cholangiocarcinoma (cHC-CC) is found unexpectedly in explanted or resected liver specimens. The current study evaluated the longterm outcomes of living-donor liver transplantation (LDLT) between patients with cHC-CC and hepatocellular carcinoma (HCC). PATIENTS AND METHODS We performed 178 LDLT including 8 patients of(More)
BACKGROUND In order to improve the prognosis of gastric cancer patients, the timely identification of second primary cancers is considered to be a crucial clinical problem. METHODS We analyzed the clinicopathological data of 2250 patients with gastric cancer with regard to both synchronous and metachronous second primary cancers. RESULTS Of 2250(More)
Re-epithelialization is essential for gastrointestinal ulcer and cutaneous wound healing. It requires epithelial cell migration and proliferation, processes that are stimulated by epidermal growth factor (EGF), and dependent on the cell cytoskeleton. Activation of Src and focal adhesion kinase (FAK) has been implicated in EGF-stimulated cell migration.(More)
BACKGROUND We aimed to evaluate the efficacy and long-term outcome in surgical microwave therapy (MW) for patients with unresectable hepatocellular carcinoma (HCC). METHODS An institutional review board approved and single-institutional study of surgical MW of unresectable HCC was conducted from May 2003 to December 2010. The median follow-up period was(More)
Nonsteroidal anti-inflammatory drugs (NSAIDs) block prostaglandin synthesis and impair healing of gastrointestinal ulcers and growth of colonic tumors, in part, by inhibiting angiogenesis. The mechanisms of this inhibition are incompletely explained. Here we demonstrate that both nonselective (indomethacin) and COX-2-selective (NS-398) NSAIDs inhibit(More)
Small-for-size (SFS) graft syndrome is one of the major causes of graft loss in living donor liver transplantation (LDLT). We examined whether splenectomy is beneficial for overcoming SFS graft syndrome in LDLT. The patients were classified into two groups: the Sp (-) group (n=69), in which splenectomy was not performed, and the Sp (+) group (n=44), in(More)
BACKGROUND AND AIM Balloon-occluded retrograde transvenous obliteration (B-RTO) is a new alternative treatment for gastric varices (GVx), but the long-term efficacy is not known. We investigated the long-term effects of B-RTO on rebleeding, prevention of first bleeding, mortality and occurrence of risky esophageal varices (EVx). METHODS B-RTO was(More)
