Biliary complications remain a major concern after living donor liver transplantation. We describe a pediatric case who underwent a successful endoscopic balloon dilatation of biliary-enteric stricture following living donor liver transplantation using a newly developed method of enteroscopy. The 7-year-old boy with late biliary stricture of(More)
Bilioenteric anastomotic stricture after liver transplantation is still frequent and early detection and treatment is important. We established the management using double-balloon enteroscopy (DBE) and evaluated the intractability for bilioenteric anastomotic stricture after pediatric living donor liver transplantation (LDLT). We underwent DBE at Jichi(More)
To improve the welfare of experimental animals, investigators seek to respect the 3R principle (Replacement, Reduction, and Refinement). Even when large animal studies are essential before moving to clinical trials, it is important to look for ways to reduce the number of experimental animals used. At the Center for the Development of Advanced Medical(More)
We encountered two cases of pediatric living-related liver transplant recipients who showed increases in blood concentration of cyclosporine or tacrolimus, a dual substrate for cytochrome P450 (CYP) 3A and P-glycoprotein (P-gp), during a diarrheal episode. To investigate the effect of intestinal inflammation on the metabolic and efflux pump activities, we(More)
Hepatic artery complications after living donor liver transplantation (LDLT) can directly affect both graft and recipient outcomes. For this reason, early diagnosis and treatment are essential. In the past, relaparotomy was generally employed to treat them. Following recent advances in interventional radiology, favorable outcomes have been reported with(More)
Early hepatic artery complications after liver transplantation in children, having undergone LDLT, can directly affect graft and recipient outcomes, making early diagnosis and treatment essential. In the past, laparotomy (thrombectomy or reanastomosis) was generally employed to treat early hepatic artery complications. Recently, favorable outcomes of IR(More)
OBJECTIVES Cholestatic liver disease (CLD) is the main indication for liver transplantation in children. This retrospective study evaluated the outcomes of living donor liver transplantation (LDLT) in children with CLD. METHODS One hundred fifty-nine children with CLD who underwent 164 LDLT between May 2001 and May 2011 were evaluated. Their original(More)
Hepatopulmonary syndrome (HPS) is a progressive, deteriorating complication of end-stage liver disease (ESLD) that occurs in 13–47% of liver transplant candidates. Although LT is the only therapeutic option for HPS, it has a high morbidity and mortality, especially in patients with severe hypoxemia before transplantation, but the course of HPS after living(More)
OBJECTIVE A new strategy is required in order to regenerate a meniscus for extensive defects. Synovial mesenchymal stem cells (MSCs) are an attractive cell source for meniscus regeneration due to their high proliferation and chondrogenic potential. We examined the effect of repetitive intraarticular injections of synovial MSCs on meniscus regeneration in a(More)
We evaluated the growth curves of children with BA after LDLT, and identified factors influencing growth velocity one-yr after LDLT (DeltaZ). The clinical data of 51 children with BA, who had an LDLT at our center from 2001 to 2005, were retrospectively reviewed. The Z scores for height and weight, and DeltaZ were studied. The correlation between DeltaZ and(More)
