Objective:
To determine early or late post surgical complications secondary to simple and complex gastroschisis.

Methods:
The association between early (acid-base disorders, electrolyte disturbances and presence of hypoalbuminemia), and late postnatal complications (respiratory, gastrointestinal, infectious) was investigated in newborn.

Results:
42 children, 54.8% male, 73.8% premature, average gestational age of 35.6±2.5 gestational weeks of age (GWA), weight 2147±537gr, they have a NICU stay of 192±14 days, PNT of 19.2±20 days, mortality of 26.2%. The frequent immediate postoperative complications were base-acid imbalance; the metabolic acidosis was associated to simple gastroschisis (p=0.049). The complex gastroschisis was associated to necrotizing enterocolitis (p=0.025), surgical closure type (p=0.003), reinterventions (p=0.025).

Conclusion:
Acid-Base alterations (76.1%), hypoalbuminemia (59.5%) as early complications and Late sepsis (40.4%), cholestasis (26.1%) as late complications are the most common in patients with Gasthoschisis.
