We report a case of torsion of an accessory lobe of the liver (ALL) in a 14-year-old girl. The patient was admitted for acute abdominal pain and laparotomy revealed an ALL, the pedicle of which was elongated with 180° torsion. The diagnosis was not made preoperatively because of the rarity of this condition. However, a close relationship between omphalocele(More)
BACKGROUND/AIMS Although advanced liver fibrosis is a critical complication in influencing the outcome of biliary atresia (BA), the mechanism is poorly understood. In adult hepatic disorders, the relationships between sinusoidal liver cells (SLC) such as hepatic stellate cells (HSCs), some growth factors and enzymes concerned with extracellular matrix (ECM)(More)
We recently treated a 14-year-old girl with a clinically and histologically diagnosed with adenoma of the nipple. Enucleation of a mass preserving the nipple was successfully performed. Adenoma of the nipple is a rare disease which is often mistaken clinically for Paget's disease. About 200 cases of the tumors have been reported worldwide so far. The most(More)
BACKGROUND Sonographic demonstration of extramural and intrapancreatic junction of the pancreatic and bile ducts, pathognomonic for pancreatico-biliary maljunction (PBM), is not easy in pediatric patients. We measured sonographic thickness of the gallbladder (GB) and retrospectively examined correlation of it with PBM. METHODS Twenty-seven children with(More)
AIM To analyze the efficacy of routine intraoperative ultrasound (IOUS) as a guide for understanding biliary tract anatomy, to avoid bile duct injury (BDI) after laparoscopic cholecystectomy (LC), as well as any burden during the learning period. METHODS A retrospective analysis was performed using 644 consecutive patients who underwent LC from 1991 to(More)
Pancreatoblastoma in childhood is a very rare malignant tumor, but is considered to have a relatively good prognosis because of its low metastatic potential. We report 1-day-old female infant who was recently found to have an intraabdominal cyst on prenatal ultrasound examination. The tumor was a unilocular, cystic mass without invasion or metastasis to(More)
The eye fixation related potential (EFRP) associated with the occurrence of fixation pauses can be obtained by averaging EEGs at termination of saccades. EFRP is a kind of ERP measurable at the eye movement situation. Variations of EFRP were examined during a proof reading task for a long time. Two paragraphs of sentences were presented on the left and the(More)
BACKGROUND/AIMS Inflammatory cytokines, such as interleukin-1 beta and tumor necrosis factor-alpha, which activate neutrophils, contribute to hepatic warm ischemia-reperfusion injury. However, the role of the cytokines in hepatic microcirculation immediately after reperfusion is still unclear. This study was carried out to investigate whether FR167653, a(More)
Biliary atresia (BA) is diagnosed by ultrasound (US) examination of the hepatic artery and gallbladder. This study was designed to assess the usefulness of the hepatic artery resistance index (HRI) measured by Doppler ultrasonography (DUS) for prognostication of liver viability in children with BA. Seventeen patients with non-correctable BA were examined by(More)
