Omphalocele and gastroschisis: prenatal diagnosis and peripartal management. A case analysis of the years 1989-1997 at the Department of Obstetrics and Gynecology, University of Homburg/Saar.

OBJECTIVE: The article presents a retrospective analysis (1989-1997) of the prenatal diagnosis, the course and completion of pregnancy of 26 fetuses with omphalocele and 18 fetuses with gastroschisis. SUBJECTS: 44 pregnancies with anterior fetal wall defect diagnosed by prenatal ultrasound, clinical or patho-anatomic examination between 1989 and 1997 at the Department of Obstetrics and Gynecology, University of Homburg/Saar. RESULTS: In 40 of 44 pregnancies (91%) the fetal ventral abdominal wall defect could be detected antenatally with ultrasound. Associated malformations in fetuses with omphalocele were seen in 18 cases (69%), whereas only five fetuses with gastroschisis (28%) had an associated malformation. Nineteen of 26 fetuses (73%) with omphalocele had a normal karyotype. Seven of 26 fetuses (27%) with omphalocele had an abnormal karyotype. Eleven fetuses with omphalocele were live born, three of them with minor anomalies. Ten babies with omphalocele survived. No chromosomal anomalies were detected in fetuses with gastroschisis. There were four gastrointestinal malformations and one lethal associated malformation in fetuses with gastroschisis. There were 15 live born babies with gastroschisis, all of whom have survived. In 20 of 44 cases (45%) with ventral abdominal wall defect oligohydramnios could be detected by ultrasound. In 28 of 44 cases (64%) we found fetal growth retardation <10th percentile for gestational age. CONCLUSION: In case of a fetal ventral abdominal wall defect, the detection and appropriate classification of associated fetal anomalies is of great importance for the further course of pregnancy. Fetal karyotyping should be offered in case of a fetal abdominal wall defect. Early and close prenatal consultation of the neonatologist and the pediatric surgeon will favorably influence the perinatal outcome.

[Spinal anesthesia for surgery of inguinal hernia in infants at risk for respiratory complications. Initial experiences with 12 patients].

11 former premature babies born at a mean gestational age of 32 weeks (range 27-34 weeks) and one baby born at term with congenital diaphragmatic hernia scheduled for inguinal hernia repair were selected to receive a spinal anaesthesia after informed written consent was obtained from one of the parents. At birth, 10 infants were intubated and received assisted ventilation; the remaining two were on nasal CPAP for 24 hours after birth. The mean post-conceptual age of the former premature infants on the day of surgery was 39 weeks (range 36-43 weeks), the mean weight was 2.2 kg (range 1.8 to 3.6 kg). One boy with congenital diaphragmatic hernia who was intubated for 19 days after birth aged 4 months on the day of operation and weighed 5.3 kg. None of the children was oxygen-dependent on the day of surgery. Spinal anaesthesia was performed in 3 children in the lateral decubitus and in 9 children in the sitting position. In each group, there was one case when spinal anaesthesia could not be performed due to a bloody spinal tap. These children received general anaesthesia, one of them in combination with a caudal block. The 9 former premature received 0.6 ml isobaric bupivacaine 0.5%, and the child born on term with diaphragmatic hernia 0.8 ml isobaric bupivacaine 0.5%. The onset of the motor blockade in the former preterm infants was within 60-90 seconds, while in the older child the onset was 10 minutes. With the given dose, the operation could be performed without any problems.(ABSTRACT TRUNCATED AT 250 WORDS)

[Localization diagnosis and differential diagnosis of postoperative intraperitoneal abscesses using 99m technetium-stannum-colloid-marked granulocytes].

Occult intraperitoneal abscesses are difficult to locate and dispose of. Therefore, a method of examination is needed that is specific, can be used at any time, is not expensive, and yields early results within 2-3 h. This seems possible with a new methods of examination. 99mTc-Sn colloid was used to label autologous polymorphonuclear leukocytes which, when reinjected, emigrate to the site of the suspected abscess. Standard scintigraphy localizes the labeled inflammatory cells. In 32 surgical patients, 34 scans were performed with good results (controlled by greyscale ultrasound); 17 (53.1%) scans represented intraperitoneal abscesses; 3 (9.4%) scans demonstrated true positive extra-abdominal inflammations.

[Spinal traction syndrome].

The causes of Spinal-Traction-Syndrome are discussed in a case of marked Spinal-Traction-Syndrome, that appeared after correction of a thoracal scoliosis, instrumented according to Harrington. On account of our case we tend to support the opinion, that the cause for the Spinal-Traction-Syndrome is to be seen rather in the mechanical obstruction of the flexura duodeno-jejunalis than in the overstretching of vagus nerve.

Prenatal and perinatal aspects of a giant fetal cervicothoracal lymphangioma.

A massive cervicothoracal lymphangioma was diagnosed in a fetus at 25 weeks of gestation. On ultrasound study, the mass showed septated, cystic components and extended from the right submandibular region to the right anterolateral thoracic wall including the right axilla and right scapula. Close sonographic follow-up revealed an increase in the size of the lymphangioma without fetal hydrops. An interdisciplinary approach including a pediatric surgeon, neonatologist, perinatologist and anesthesiologist was chosen. Elective cesarean section under general anesthesia was planned at 37 + 0 weeks of gestation. Surgical correction of the lymphangioma was successfully performed on the 4th day of life. Possible differential diagnoses and the obstetrical management are presented.
