Background/purpose: Standard treatment of large hepatoomphaloceles has been SILASTIC (Dow Corning, Midland, MI) silo placement followed by closure. This requires two operations, and complications from the silo may occur. The authors have looked for a safe and simpler alternate method of closure. Delayed external compression reduction of an omphalocele (DECRO), appears to have a low complication rate and a rapid time to closure.
Methods: The authors reviewed retrospectively the records of six patients with hepato-omphaloceles treated with DECRO from August 1993 to July 1997. All defects were evaluated by the attending surgeon and could not be closed primarily. All data are expressed as mean +/- SEM.
Results: The average gestational age was 36.5 +/- 0.67 weeks with mean weight of 2,780 +/- 256 g. Two patients had congenital cardiac disease. The mean size of the defects was 6.2 x 5.7 cm. All defects had the liver out of the abdomen. No patients required silo placement. The mean time to reduction and final closure was 5.6 +/- 0.49 days. The average postoperative time on the ventilator was 7.1 +/- 3.5 days. Mean time to full feeds was 18.8 +/- 3.4 days. One patient had superficial necrosis of the skin flap. Mean time to discharge was 30.5 +/- 5.5 days. All patients had DECRO completed without complications.
Conclusions: This procedure decreases the number of operations needed from two to one. No complications were seen from the procedure and the time of mechanical ventilation required was low. The abdominal compartment syndrome developed in none of the patients. DECRO is a safe and very effective alternative to SILASTIC silo placement in moderate and large omphaloceles that cannot be closed primarily.
