Prediction of outcome in omphalocele and gastroschisis by intraoperative measurement of intravesical pressure.

Author information

Department of Surgery, Veterans General Hospital-Taipei, Taiwan R.O.C.


A simple and accurate measurement of intraabdominal pressure is essential to predict a successful closure of defects in omphalocele and gastroschisis. Intravesical pressure (IVP) is a close estimation of intraabdominal pressure and can be measured safely by placing a catheter in the urinary bladder during surgery. Three neonates with gastroschisis and four with omphalocele were studied. Pressure-related complications such as ascites leakage, ventral hernia, impaired venous return of the lower extremities, and oliguria developed only in the patients with IVP > 20 mmHg after fascial closure. Prolonged hospitalization, ventilation support and intensive care were required for these patients.
