Complete mobilization of the liver before parenchymal transection has been a standard approach during major hepatectomy. This safe approach is not always feasible for the cases in which it is difficult to mobilize the hepatic lobe involved by large tumors with diaphragmatic invasion. Recently, anterior approach for the right-sided hepatic resection was(More)
Smaller-size infants undergoing living-donor liver transplantation (LDLT) are at increased risks of vascular complications because of their smaller vascular structures in addition to vascular pedicles of insufficient length for reconstruction. Out of 585 child patients transplanted between June 1990 and March 2005, 64 (10%) weighing less than 6 kg underwent(More)
To address the current role of liver transplantation (LT) for urea cycle disorders (UCDs), we reviewed the worldwide English literature on the outcomes of LT for UCD as well as 13 of our own cases of living donor liver transplantation (LDLT) for UCD. The total number of cases was 51, including our 13 cases. The overall cumulative patient survival rate is(More)
The development of portopulmonary hypertension (PH) in a patient with end-stage liver disease is related to high cardiac output and hyperdynamic circulation. However, PH following liver transplantation is not fully understood. Of 617 pediatric patients receiving transplants between June 1990 and March 2004, 5 (median age 12 yr, median weight 24.5 kg) were(More)
To analyze the risk factors in the development of hepatic artery thrombosis (HAT) and assess the impact of our perioperative management for HAT on the long-term outcome after pediatric living donor liver transplantation (LDLT), we reviewed 382 patients under 12 yr of age who underwent 403 LDLT from January 1996 to December 2005. One- and 10-yr patient(More)
BACKGROUND In pediatric living donor liver transplantation, left lateral segment or monosegmental graft is used to overcome size discrepancies between adult donors and pediatric recipients. For neonates and extremely small infants, however, problems related to large-for-size graft are sometimes encountered even when using such grafts. The reduced(More)
The authors reviewed 6 cases of giant cell tumor of bone with pulmonary metastases, analyzed the growth rate of the metastases, and performed flow cytometry on paraffin blocks from primary and metastatic lesions. Surgery on the pulmonary metastases was done in 3 cases. Chemotherapy was administered in all 6 cases. If the doubling time of the pulmonary(More)
BACKGROUND Prognostic factors for patients with advanced biliary tract cancer (BTC) who received palliative chemotherapy have not been fully established. Especially, the status of unresectable/recurrent disease has not been well studied because of a small number of patients with recurrent BTC in previous studies. METHODS This multicenter retrospective(More)
Ovarian mucinous cystadenomas are benign epithelial neoplasms that occur most often in the third to sixth decade of life. Ovarian mucinous cystadenoma can be classified into 3 categories (benign, borderline malignancy, malignancy) based on histopathologic evaluation. Premenarchal cases of ovarian mucinous cystadenoma of borderline malignancy are exceedingly(More)
