Management and outcome in prenatally diagnosed sacrococcygeal teratomas.

BACKGROUND: The aim of the present study was to retrospectively determine the clinical factors affecting the outcome after birth in prenatally diagnosed sacrococcygeal teratomas (SCT). METHODS: Six cases of prenatal SCT were identified from January 1985 until August 2005. A retrospective review of case-notes and pathological reports was carried out. Clinical data during the perinatal period, operative findings, postoperative complications and follow up were evaluated in the patients with prenatally diagnosed SCT. RESULTS: SCT presented as type I in two neonates and type III in four between 22 and 33 weeks' gestation. Fetal intervention was not performed for any fetus. Five of six were delivered by cesarean section and the other was delivered vaginally due to small tumor size. Patients were born at between 29 and 39 weeks' gestation and weighed from 1840 to 3500 g. All patients with type III SCT presented with related diseases, including bilateral hydronephrosis, neurological deficit of the communicating peroneal nerve such as paralytic talipes equines, bladder or bowel dysfunction, high-output cardiac failure, or fetal hydrops in one of a set of fraternal twins. A baby with high-output cardiac failure and fetal hydrops underwent urgent cesarean section at 29 weeks' gestation and died 8 days after birth despite intensive care due to multi-organ failure. In five cases, surgery was successful with good outcomes maintained at follow-up of between 8 months and 14 years. CONCLUSIONS: Detailed ultrasound should be performed to rule out associated anomalies, and determine the presence or absence of hydrops in prenatally diagnosed SCT. Fetal hydrops, orthopedic impairment such as lower extremity weakness and swelling, and urinary incontinence are important clinical factors affecting the outcome after birth in prenatally diagnosed SCT. In particular, the present study indicated that the association of a fraternal twin and fetal hydrops makes it very difficult to treat SCT perinatally.

Postnatal management for prenatally diagnosed choledochal cysts.

PURPOSE: The aim of this study was to determine an appropriate postnatal management plan for prenatally diagnosed congenital biliary dilatation (CBD). METHODS: Between 1962 and 2002, 5 (5.9 %) of 85 patients had CBD diagnosed prenatally and were examined clinically. Of these 5 patients, 2 (group A) underwent delayed primary definitive surgery after percutaneous transhepatic cholangiodrainage (PTCD), 1 (group B) underwent early definitive surgery in the neonatal period, and 2 (group C) underwent delayed primary definitive surgery without PTCD in early infancy (within 6 months after birth). The clinical data, operative findings, intra- and postoperative complications, and follow-up were evaluated in these 3 groups. RESULTS: There were no postoperative complications, such as catheter-related complications, in group A. However, there was adhesion around the choledochal cyst, and the operation was therefore difficult in group A. The diameter of the anastomosis in the hepaticojejunostomy was small, and the cyst wall was thin in group B. Consequently, anastomotic leakage of the hepaticojejunostomy occurred in group B. Neither operative nor postoperative complications such as anastomotic leakage or stenosis occurred in group C. Slight fibrosis of Glisson's sheath was seen in 2 patients of groups A and C. No liver cirrhosis was seen in any group. CONCLUSIONS: The authors propose that asymptomatic patients should undergo elective definitive surgery by 6 months of age. For symptomatic patients, especially when a differential diagnosis of type I cystic biliary atresia is doubtful, early definitive surgery is needed before 2 months of age. PTCD appears to be indicated only under certain circumstances, and delayed primary definitive surgery should be performed as early as possible thereafter.
