1/49. Fetal meconium peritonitis after maternal hepatitis A.hepatitis a virus has rarely been implicated in congenital infections. After maternal hepatitis A at 13 weeks' gestation, ultrasonographic examinations revealed fetal ascites (20 weeks) and meconium peritonitis (33 weeks). After delivery, a perforated distal ileum was resected. Elevated levels of hepatitis A immunoglobulin g persisted in the infant 6 months after delivery.- - - - - - - - - - ranking = 1keywords = meconium (Clic here for more details about this article) |
2/49. Disseminated intravascular meconium in a newborn with meconium peritonitis.A 3-day-old premature infant with meconium peritonitis, periventricular leukomalacia, and pulmonary hypertension died with respiratory insufficiency. An autopsy disclosed intravascular squamous cells in the lungs, brain, liver, pancreas, and kidneys. Numerous pulmonary capillaries and arterioles were occluded by squamous cells, accounting for pulmonary hypertension. brain parenchyma surrounding occluded cerebral vessels showed infarct and gliosis. A mediastinal lymph node filled with squamous cells alluded to the mechanism by which these cells from the peritoneal cavity likely entered the bloodstream--namely, via diaphragmatic pores connecting with lymphatics. Thus, disseminated intravascular meconium rarely may complicate meconium peritonitis and have devastating consequences.- - - - - - - - - - ranking = 2.2keywords = meconium (Clic here for more details about this article) |
3/49. Ultrasonographic detection of intrauterine intussusception resulting in ileal atresia complicated by meconium peritonitis.A neonate with ileal atresia (IA) complicated by meconium peritonitis (MP) whose prenatal ultrasonography (US) detected an intrauterine intussusception (IUI) is reported. Fetal ascites, dilated bowel loops, and abdominal calcifications were identified on serial US from 25 weeks of gestation. Intestinal loops with high echogenecity and a "target-like" appearance suggestive of IUI were detected in the right lower quadrant. The 2,680-g male was delivered vaginally at term and underwent a laparotomy. Fibrous adhesions and small calcifications were scattered throughout the peritoneal cavity. IA (interrupted type) was confirmed 17.0 cm cranial to the ileocecal valve (ICV). An ileo-ileal intussusception was also found between 16.5 cm and 9.0 cm cranial to the ICV. Partial resection of the ileum and an ileo-ileal anastomosis was performed. The postoperative course was uneventful. In this case, the pathological process of IUI resulting in IA and MP was demonstrated sonographically by identifying the "target-like" appearance in the fetus.- - - - - - - - - - ranking = 1keywords = meconium (Clic here for more details about this article) |
4/49. meconium peritonitis.meconium peritonitis can have a wide range of presentations. This report discusses two cases that have recently appeared in our neonatal intensive care unit. The first report discusses the case of a meconium pseudocyst in a preterm infant. The second case reports on a newborn baby with a healed bowel perforation during the prenatal period. Finally, a brief discussion of meconium peritonitis is also included.- - - - - - - - - - ranking = 0.4keywords = meconium (Clic here for more details about this article) |
5/49. Idiopathic origin of meconium peritonitis.A 26-year-old, gravida 3 presented at 31 weeks of gestation with polyhydramnios. On ultrasound there was marked foetal ascitis with unilateral hydrocele. Patient delivered a 3.15 kg, large-for-date baby at 33 weeks and 3 days of gestation. On basis of clinical, radiological and sonographic features, diagnosis of meconium peritonitis was made. Ascitic tapping was done. Surgery was withheld, as there were no signs of intestinal obstruction. dna testing for cystic fibrosis was negative. Baby did not deteriorate so he was discharged. Baby was doing well on 2 months follow up. Hydrocele and ascitis were resolving. Rarely meconium peritonitis may occur without an underlying cause when peritonitis may be innocuous and intervention may not be required.- - - - - - - - - - ranking = 1.2keywords = meconium (Clic here for more details about this article) |
6/49. Changes in fetal heart rate pattern after intrauterine paracentesis in one twin with meconium peritonitis.We report a case of in utero paracentesis of ascites in a fetus with meconium peritonitis due to volvulus at 34 weeks which resulted in the correction of an abnormal fetal heart rate pattern and enabled vaginal delivery by preventing abdominal dystocia. The intrauterine intervention also helped to establish the diagnosis and potentially reduced the respiratory compromise after birth.- - - - - - - - - - ranking = 1keywords = meconium (Clic here for more details about this article) |
7/49. Fetal meconium peritonitis in single and twin pregnancy. Two cases report.We present two cases of fetal meconium peritonitis in a single and twin pregnancy, respectively. The first case diagnosis was made at 30 weeks and was confirmed after delivery of the twins by cesarean section at 37 weeks. The second case diagnosis was made at 31 week and was confirmed at 37 weeks. meconium peritonitis is a rare prenatal complication that results from intrauterine perforation of small bowel with spillage of sterile meconium into peritoneal cavity. We now report two cases of meconium peritonitis diagnosed at 30 and 31 weeks gestation.- - - - - - - - - - ranking = 1.4keywords = meconium (Clic here for more details about this article) |
8/49. cystic fibrosis presenting as fetal anemia. A case report.BACKGROUND: cystic fibrosis in the fetus may present with meconium ileus, seen as dilated, hyperechogenic bowel on the prenatal ultrasound examination. Rarely does in utero bowel perforation occur with resulting peritoneal echogenicity, ascites or lack of bowel dilation. CASE: In a case of cystic fibrosis in a fetus, all three findings above occurred, as did anemia, most likely secondary to bleeding from perforated bowel. The anemia was detected following the finding of significantly elevated peak flow velocity in the middle cerebral artery (MCA). CONCLUSION: Fetuses with cystic fibrosis can develop anemia. MCA peak flow velocity measurements are helpful in detecting the anemia.- - - - - - - - - - ranking = 0.2keywords = meconium (Clic here for more details about this article) |
9/49. Fetal meconium peritonitis in the infant of a woman with fulminant hepatitis b. A case report.BACKGROUND: Simultaneous fulminant maternal hepatitis b infection and fetal meconium peritonitis has never been reported before in the English-language literature. CASE REPORT: Fetal meconium peritonitis was detected at 32 weeks' gestation in a 21-year-old woman suffering from fulminant hepatitis. Fulminant hepatitis b was confirmed by clinical observation and serologic examination results. The course was also complicated with preterm labor. The fetus was diagnosed with meconium peritonitis prenatally. Because of failed tocolytic treatment, the fetus was delivered vaginally. Both the mother and fetus received intensive care, and the mother recovered. In contrast, the fetus's course worsened due to progressive abdominal distension. Although exploratory laparotomy was attempted, the operation was not successful. The infant died five days after birth. CONCLUSION: Recognition of the predisposing factors in fetal meconium peritonitis and immediate referral to a tertiary medical center, where specialists are available, could help physicians determine an accurate diagnosis and might improve prognosis.- - - - - - - - - - ranking = 1.6keywords = meconium (Clic here for more details about this article) |
10/49. Congenital fibrosarcoma of the jejunum in a premature infant with meconium peritonitis.We report an unusual case of perforation of a congenital fibrosarcoma of the jejunum in utero and secondary meconium peritonitis. Prenatal ultrasound showed polyhydramnios and fetal ascites from 25 gestational weeks in the absence of other fetal congenital anomalies. A 2200 g baby girl was born at 34 weeks gestation, presenting with severe generalized edema and respiratory distress immediately after birth. Plain radiography revealed progressive abdominal distension and pneumoperitoneum. The baby subsequently underwent surgery at the age of one day. A perforation of the upper jejunum, which had resulted in meconium peritonitis, was discovered intraoperatively and the perforated section of the intestine was resected and anastomosed successfully. The postoperative course was uneventful. Pathological examination confirmed that the perforation was caused by rupture of a congenital fibrosarcoma originating from the jejunum. rupture of a malignant tumor is an extremely rare cause of peritonitis in the fetus and neonate.- - - - - - - - - - ranking = 1.2keywords = meconium (Clic here for more details about this article) |
