title: Gastroschisis wringer clamp: a safe, simplified method for delayed primary closure.
abstract: When primary abdominal wall closure in a newborn with gastroschisis cannot be accomplished safely, placement of a reinforced Silastic silo facilitates delayed primary closure (DPC). In this report we describe our experience with the gastroschisis wringer clamp (GWC). The GWC is an autoclavable, 140-g, aluminum alloy device reminiscent of an old wringer washing machine. It consists of two apposing serrated rollers that pull the Silastic silo through a slotted base plate. This protects the intestine and converts the circular defect into a vertical slit to ease DPC. The GWC is adjusted daily on the awake newborn in the nursery and the magnitude of each adjustment is gauged by the infant's cardiac and pulmonary status. For the past 10 years we have cared for 116 newborns with gastroschisis. The average birth weight was 2,530 g (range, 1,380 to 3,300 g). Eighty-six infants (74.1%) have undergone primary closure. The remaining 30 infants (25.9%) were treated by placement of a Silastic silo and application of the GWC, forming the basis of this report. The DPC operation was performed an average of 6.7 days (range, 3 to 23 days) following the application of the silo. Extubation was usually possible prior to the DPC, with the mean length of mechanical ventilation being 3.8 days. Three patients developed serious complications including two dehiscences of the silo-fascia interface. There were no deaths in this group of 30 patients. The GWC offers many technical advantages and can be easily reversed when the infant's cardiopulmonary status deteriorates. We advocate its adoption as a method of choice in the newborn with gastroschisis who requires DPC.
