AIM The current study aimed to assess the perinatal risk of congenital cystic lung diseases (CCLD) and to establish a suitable surgical strategy in consideration of postoperative lung growth and problems during adulthood. METHODS Among 874 CCLD patients identified in a nationwide survey, 428 patients were born between 1992 and 2012 and treated at 10(More)
The optimal management of microcystic lymphatic malformations (LMs) in children has not been established. We describe how we used the Ligasure™ Vessel Sealing System (LVSS) to achieve partial resection of refractory microcystic LMs in a 1-year-old boy. The child was admitted in respiratory distress caused by infection and swelling of cervical LMs. The LMs(More)
AIM Disorders of protein metabolism in liver cirrhosis can affect prognosis or cause complications. Treatment with branched-chain amino acid (BCAA) and zinc supplements has been shown to be effective against abnormal nitrogen metabolism in liver cirrhosis. There are, however, few studies on the effects of combining these supplements. In this study, the(More)
INTRODUCTION Intrahepatic bile duct (IHBD) stones are one of the most complicated morbidities that occur after Roux-en-Y hepaticojejunostomy (RYH); however, the optimal therapeutic approach is controversial. METHODS Double-balloon enteroscopy (DBE) has been widely and frequently performed even in pediatric patients. We herein report the successful(More)
Blunt trauma to the abdomen accounts for the majority of abdominal injuries in children. Pancreatic injury is the fourth most common solid organ injury, following injuries to the spleen, liver and kidneys. The most common complications are the formation of pancreatic fistulae, pancreatitis and the development of pancreatic pseudocysts, which usually present(More)
Neonates with congenital tracheal stenosis (CTS) sometimes develop respiratory distress and may be difficult to intubate. We used balloon tracheoplasty with a rigid bronchoscope for emergency airway management in neonates with symptomatic CTS. Herein, we describe the balloon tracheoplasty procedure and the early outcomes following its use as the initial(More)
BACKGROUND AND STUDY AIMS Endoscopic submucosal dissection (ESD) has become widely accepted as a minimally invasive treatment for early gastric cancer (EGC), and opportunities to use ESD to treat EGC in elderly patients are increasing. The objective of this study was to elucidate the safety and efficacy of ESD in elderly patients. PATIENTS AND METHODS(More)
Successful prophylactic administration of Helicobacter pylori whole cell sonicate (WCS) plus complete Freund's adjuvant (CFA) or aluminum hydroxide (ALM) against subsequent H. pylori infection was reported recently. Here we tested the effect of WCS plus TiterMax Gold (TMX) or ALM in mice with chronic H. pylori infection. Mice with chronic (18 weeks) H.(More)
AIM Liver cirrhosis is often accompanied by zinc deficiency. The exact mechanisms underlying zinc deficiency remain unclear. This study was undertaken to clarify the influence of diuretics on blood zinc levels and zinc excretion in urine in liver cirrhosis. METHODS Seventy-nine outpatients with liver cirrhosis were divided into four groups: (i) patients(More)
PURPOSE Malignant rhabdoid tumor of the kidney (MRTK) is a rare and highly aggressive malignancy of infanthood. In an effort to delineate MRTK progression, we investigated the metastatic fate of some MRTK cells using xenotransplantation animal models and the tumor-initiating potential of CD133(+) MRTK cells. EXPERIMENTAL DESIGN We established two MRTK(More)
