Hepaticojejunostomy is a standard biliary reconstruction method for infantile living donor liver transplantation (LDLT), but choledochocholedochostomy for infants is not generally accepted yet. Ten pediatric recipients weighing no more than 10 kg underwent duct-to-duct choledochocholedochostomy (DD) for biliary reconstruction for LDLT. Patients were(More)
Little attention has been paid to a ligation of the spontaneous portosystemic shunt in adult living donor liver transplantation (LDLT). A 33-year-old Japanese man with cryptogenic liver cirrhosis accompanied by a huge splenorenal shunt underwent LDLT. Acute cellular rejection produced “to and fro” portal venous flow on postoperative day (POD) 10. Steroid(More)
BACKGROUND Hepatic outflow block is one of the major complications leading to severe graft dysfunction after left lobe living donor liver transplantation (LDLT). METHODS Medical records of 46 recipients of a left lobe LDLT were reviewed. The method of outflow reconstruction and post-transplant morphological changes of hepatic veins were investigated. The(More)
BACKGROUND There are only limited data on post-transplant ascites unrelated to small-sized grafts in living donor liver transplantation (LDLT). METHODS The subjects were 59 adult patients who had received right lobe LDLT with a graft weight-to-recipient weight ratio (GRWR)>0.8%. Patients were divided into either Group 1 (n=14, massive ascites, defined as(More)
BACKGROUND We report 4 adult cases of mesenteroaxial gastric volvulus after living donor liver transplantation (LDLT). RESULTS All 4 recipients were female with a median age of 31 years (range, 21-69). All had undergone right lobe LDLT. Gastric volvulus developed on postoperative days (POD) 4-30, and all were successfully treated with an endoscopic(More)
BACKGROUND Systemic immunosuppression represents the major factor for cancer recurrence after orthotopic liver transplantation for hepatocellular carcinoma (HCC). Rapamycin is an immunosuppressant with unique antitumoral properties. Although rapamycin has been successfully used in HCC patients after liver transplantation, the detailed mechanisms of(More)
LLS reduction has been frequently used in infants weighing <7 kg. Twenty recipients weighing <7 kg at the time of LDLT, median age 11.0 months and body weight 5.6 kg, were treated with an RLLS (n = 12) or LLS (n = 8) graft. Absolute indication of size reduction was that the estimated GRWR was >4.0%. Even if the preoperative GRWR was <4.0%, the RLLS graft(More)
The purpose of this study is whether the fungal deoxyribonucleic acid (DNA) examination is useful as a sensitive parameter for pediatric surgical patients with mycosis. The eleven episodes of five cases (4 cases; progressive liver disease after biliary atresia operation, 1 case; short bowel syndrome and long term total parenteral nutrition with megacystis(More)
To re-evaluate the impact of recipient age on the outcome of LDLT for BA in an era in which LDLT is the established treatment for BA in Japan. Thirty-one patients with BA who underwent LDLT were divided into four groups regarding the age at LDLT: infants <1 yr old (group A; n = 14); young children 1 to 6 yr old (group B; n = 8); school children 6 to 15 yr(More)
We examined differences in host immunologic changes induced by the intravenous or intraportal administration of donor antigens at engrafting and evaluated their contribution to graft survival using a rat transplantation model. Lewis rat recipients were given either an intravenous or intraportal injection of donor splenocytes (1 × 108) immediately after(More)
