Vacuum-assisted closure: a new method for treating patients with giant omphalocele.
BACKGROUND
Closure of giant omphalocele can present a surgical challenge. Neither silo, skin flap, nor primary closure has been successful in treating all patients. We present a novel application of the vacuum-assisted closure (VAC) device, which allows for improved results in these difficult cases.


METHODS
The VAC device (KCI, San Antonio, Tex) consisted of a sponge applied directly to the bowel and liver, covered with impermeable transparent dressing, and attached to a low negative pressure system. The sponge was changed every 3 to 5 days under local sedation.


METHODS
All 3 patients had giant omphaloceles. The first infant, a 34 week gestational age (WGA) male, was initially treated with silo reduction, which disrupted after 21 days. The large mass of bowel and liver made primary closure impossible. The VAC was applied for 45 days. The viscera was easily reduced and subsequently covered with acellular dermal matrix (AlloDerm). The VAC was reapplied, and the small remaining defect was skin-grafted. The second male infant was a 34 WGA male infant who became septic after failure of prosthetic mesh closure. The VAC was applied for 22 days after removal of the mesh. The infection resolved, and the defect size was reduced, allowing for skin flap closure. Mesh infection and development of an enterocutaneous fistula in the last patient, a 37 WGA female child, were treated by mesh removal and application of the VAC for 36 days. The VAC allowed for control of the fistula output and development of a healthy granulation bed.


RESULTS
Vacuum-assisted closure was associated with (1) rapid shrinkage and reduction of the viscera (22-45 days); (2) cleansing of the wound; (3) excellent granulation; (4) maintenance of a sterile environment; and (5) ease of use, with changes possible at the bedside.


CONCLUSIONS
The VAC device should be considered a safe and effective alternative in treating complicated cases of giant omphalocele until a more definitive closure method can be used.
