Closing arguments for gastroschisis: management with silo reduction

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