INTRODUCTION Laparoscopic procedures for inguinal hernias and hydroceles in children have become widespread in the past few decades. The purpose of this study was to perform a retrospective analysis of our experience in order to assess the safety and efficacy of laparoscopic percutaneous extraperitoneal closure (LPEC) and to compare the findings with those(More)
BACKGROUND/PURPOSE The outcome of antenatally diagnosed congenital diaphragmatic hernia (CDH) has remained poor despite aggressive therapeutic strategies. Since 1996, the authors have used a new approach including early surgery and inhaled nitric oxide (iNO). The aim of this study is to determine whether early surgery in combination with iNO improves the(More)
PURPOSE Children with neurologic and neuromuscular handicaps frequently have various symptoms related to gastroesophageal reflux (GER) disease. The long-term efficacy of antireflux surgery remains controversial in such children with GER. The clinical results of such patients who underwent laparoscopic fundoplication were examined in the current study. (More)
BACKGROUND/PURPOSE The authors compared the clinical outcome between laparoscopically assisted endorectal pull-through (EPT) with an extraanal approach (EA) and conventional abdominal approach (AB) in Hirschsprung's disease (HD), and found that the former approach was less invasive and can provide a better clinical outcome. Recently, they introduced(More)
CT-guided localization followed by video-assisted thoracoscopic surgery was performed in three children with pulmonary nodules less than 5 mm in diameter. The patients' respective primary diagnoses were Wilms tumor, hepatoblastoma, and osteosarcoma of the femur. The pulmonary nodules were marked preoperatively by a percutaneously placed hook-wire or dye(More)
BACKGROUND The aim of the present study was to evaluate the value of an end-tidal carbon monoxide corrected for inhaled carbon monoxide concentration (ETCOc) at the early neonatal period. The value would be useful for predicting subsequent hyperbilirubinemia in non-hemolytic full-term infants. METHODS The ETCOc levels were measured every 6 h during the(More)
BACKGROUND A nationwide survey on neonatal surgery conducted by the Japanese Society of Pediatric Surgeons has demonstrated that the mortality of neonatal intestinal perforation has risen over the past 15 years. The incidence of intestinal perforation in extremely low-birthweight (ELBW) neonates has been increasing as more ELBW neonates survive and as the(More)
BACKGROUND/PURPOSE Laparoscopic pyloromyotomy has recently gained wide acceptance as the optimum treatment of infantile hypertrophic pyloric stenosis (IHPS). However, medical treatment may be superior to laparoscopic surgery in invasiveness. The efficacy of our regimen of intravenous atropine therapy for IHPS was assessed in comparison with surgical(More)
There is controversy about the identity of focal intestinal perforation (FIP) and necrotizing enterocolitis (NEC). To elucidate the difference between them, we reviewed their clinical presentations. Over the last 20 years, 39 very-low-birth-weight (VLBW) neonates, including 21 extremely-low-birth-weight neonates, underwent a laparotomy for intestinal(More)
BACKGROUND/PURPOSE The incidence of hepatoblastoma (HB) in children of low birth weight is increasing. In the authors' institute, 5 infants of extremely low birth weight (ELBW) were found to have HB. The purpose of this study was to identify the characteristics of these infants to elucidate the pathogenesis of HB arising in ELBW infants. METHODS Birth(More)
