This report describes the case of an ileal perforation secondary to clamping of the exomphalos minor in 3-day-old girl. Eighteen accidental clamping or cutting cases were found in the published work. It is thought that this defect resulted from either the clamping, ligation or cutting of the bowel in a small unrecognized omphalocele. These complications are(More)
BACKGROUND Recently, minimally invasive thoracoscopic surgery has offered several options for both the diagnosis and surgical treatment in the field of pediatric surgery. This report reviews the surgical experience in order to assess the problems including the complications, encountered during thoracoscopic surgery in children under 15 years of age in the(More)
CASE REPORT A 12-year-old girl had the hair on the right side of her head pulled during a quarrel, after which a subgaleal hematoma (SGH) developed over her right cranium. The subcutaneous swelling progressed to the forehead, and a marked exophthalmos then developed on the left side. The bilateral, liquefied SGH was removed surgically, and two drainage(More)
We herein report a case of type I congenital cystic adenomatoid malformation of the lung (CCAML) with non-immune hydrops fetalis (NIHF), a mediastinal shift and polyhydramnios diagnosed at 24 weeks' gestation by ultrasonography. The fetus was treated with a cyst-amniotic shunt at 29 weeks' gestation. Following a postnatal whole resection of the right lung,(More)
Infants, especially extremely low birth weight infants (ELBWIs, birth weight <1,000 g) continue to have a high mortality after gastrointestinal (GI) perforation. In Japan, the overall mortality rate for neonates under 30 days having GI perforation was 31.6% in 2003. From 1974 to 2003, 34 cases of GI perforation in neonates were treated surgically in Fukuoka(More)
OBJECTIVE Wound dehiscence caused by surgical site infection (SSI) presents a complicated problem. Negative pressure wound therapy (NPWT) was developed to treat wound dehiscence. Nutritional treatment using arginine has also been recently shown to be effective for the treatment of pressure ulcers. Therefore, wound complications due to SSI were treated using(More)
A previous study documented the effects of maternal corticosteroid treatment on structural growth and functional development in fetal lungs associated with pathogenic conditions such as oligohydramnios using immunohistochemical and morphometric analyses. The purpose of the present study was to examine the effect of maternal dexamethasone treatment the(More)
We herein present a megacystis-microcolon-intestinal hypoperistalsis syndrome (MMIHS) case followed by ultrasound (US) examinations before birth. During the prenatal US examination of a 34-year-old woman, an enlarged bladder with bilateral hydronephrosis and hydroureter of the fetus were detected. The amniotic fluid was normal in the second trimester but(More)
This report presents the case of a 6-day-old male with cystic biliary atresia (CBA), and the cyst was detected antenatally. Antenatal ultrasonography suggested the possibility of CBA or a choledochal cyst at 16 weeks' gestation. However, the cyst disappeared during the later gestational period. The cyst was detected again by preoperative imaging. Surgical(More)
AIM The present study was carried out using electron microscopy to evaluate the expression of lamellar bodies in type II pneumocytes of fetal rabbit lungs with hypoplasia induced by oligohydramnios. METHODS Using an amniotic shunting rabbit model, the lungs obtained from 32 fetuses, including 16 experimental fetuses (shunting group) and 16 control fetuses(More)
