The aim of this article is to present a new Technique of giant omphaloceles repair in neonatal period and also later in life in patients that the primary repair has been failed. From 1999 to 2006, seven consecutive children (male/female ratio 0.4) with giant omphalocele (n=6) and Gastroschesis (n=2) were underwent this new operation in our center. In this technique, there were two operations. The mean of hospital stay was 38 days (range, 23-42 days), and full enteral feeding was achieved on the 8 to 25 postoperative day (Mean, 14 day). The final closure, in all patients was achieved between the 14 to 32 days after the first operation (Mean, 21 day). Mechanical ventilation was necessary for the mean of 5 days (range, 2-8 days). All patients are alive and have no complication due to the operation (1 month-7 years). Giant omphalocele and Gastroschesis can be safely repaired. The placement of an intraperitoneal tissue expander and traction of abdominal muscles can create the needed space for closure in several weeks in patients with giant omphalocele/ Gastroschesis.The aim of this article is to present a new Technique of giant omphaloceles repair in neonatal period and also later in life in patients that the primary repair has been failed.
