Closing arguments for gastroschisis: management with silo reduction.

Author information

  • 1Children's Memorial Hospital Chicago, IL 60614, USA.



There are two approaches to close gastroschisis. Primary closure (PC) is reduction and fascial closure; silo closure (SC) places viscera in a preformed-silo and reduces the contents over time. We have shifted from PC to SC. This study compared the outcomes of these two techniques.


Records of babies with gastroschisis from 1994-2004 were reviewed. Closure type, ventilator days, days to full-feeds, hospital days, complications, and mortality were recorded.


Twenty-eight patients underwent PC; 20 patients had SC. Differences in ventilator days, days to full-feeds, and hospital days were not statistically significant. Nine PC patients developed closure-related complications vs. none in SC (P < 0.05). Eight PC vs. two SC patients had non-closure-related complications (P < 0.05). Four PC vs. zero SC patients developed necrotizing enterocolitis (P < 0.05). Five PC vs. one SC patients had ventral hernia (P < 0.05). No patient died.


PC resulted in higher incidence of reclosure, non-closure-related complications, and necrotizing enterocolitis. Consequently, we recommend SC as the preferred treatment.
