Prenatal diagnosis and management of abdominal diseases in pediatric surgery

Purpose The aim of this study was to investigate the prenatal courses and management of abdominal surgical diseases. Methods Of the 327 patients registered with our fetal treatment board since March 2002, 83 fetuses referred to the surgical department were enrolled for the current study. The prenatal diagnosis, sequential fetal images, and perinatal courses of these cases were reviewed retrospectively. Results Of the 83 cases, abdominal diseases were suspected in 34, lung and thoracic diseases in 25, genitourinary diseases in 12, and other anomalies in 12. Meconium peritonitis (MP), intestinal obstruction, and abdominal wall defects accounted for approximately 65% of the abdominal diseases. Five patients with prenatally diagnosed lung diseases underwent fetal surgical intervention, and 17 of the 22 liveborn patients survived. In contrast, none of the patients with prenatally diagnosed abdominal anomalies underwent fetal surgical intervention, yet, 23 of the 24 liveborn patients survived. However, preterm labor and hydrops were seen frequently in the patients with giant cystic MP, suggesting a fetal critical condition. Conclusions Although the clinical outcome of abdominal diseases seemed favorable with postnatal treatment, the current results suggested the occurrence of hidden mortality in utero and the potential need for fetal intervention for some abdominal conditions, such as MP.
