Introduction: Gastroschisis and omphalocele are neonatal malformations of the abdominal wall. Despite their great differences, both are severe diseases characterized by herniation of viscera through the defect in the abdominal wall. Children with these defects present as surgical emergencies that pose a difficult challenge to the attending surgeon. Even with appropriate management, the mortality rate is between 20-40%. Omphalocele and, to a lesser degree gastroschisis, are associated with a wide range of malformations. Objective: The aim of this retrospective review was to describe the management of children with gastroschisis or omphalocele, and the results obtained with it, at the Pediatric Surgery Section, Hospital Universitario San Vicente de Paúl, in Medellin, Colombia. Patients and methods: We evaluated the charts of all patients admitted to the Pediatric Surgery Section, between January 1, 1998 and December 31, 2006, with a diagnosis of gastroschisis or omphalocele. The type of treatment was defined as either primary closure or closure by stages; accordingly, we reviewed the results of the operation, the surgical complications (surgical site infection, evisceration, sepsis, ileus and intraabdominal hypertension), the time of onset of oral and total parenteral nutrition (TPN), and the duration of hospital and UCI stay. Results: 55 patients were identified, 32 with gastroschisis and 23 with omphalocele, all of whom were surgically treated. In 31 patients (56.4%) primary closure was carried out, while in 24 ( 43.6%) the closure was done by stages; in the latter modality silo was most frequently used (12 cases). Complications, mostly sepsis, occurred in 42 patients (76.4%). The frequency of complications associated with the surgical procedure was similar for primary closure (49.9%) and for closure by stages (49.7%). Onset of the oral route was earlier in patients treated by primary closure. Patients with gastroschisis required longer hospital and UCI stays. Sixteen patients died (29.1%); mortality was higher in those with omphalocele (10/23; 43.5%) than in those with gastroschisis (6/32; 18.8%).
