Staged silo repair of gastroschisis with preservation of the umbilical cord.
BACKGROUND
The optimal surgical approach for gastroschisis remains controversial, although primary closure after vigorous stretching of the abdominal wall and decompression of the intestinal contents is currently preferred.


METHODS
Between 1984 and 1997, 24 newborns with gastroschisis were treated at Saitama Children's Medical Center. The average gestational age was 37.3 weeks, and the average birth weight was 2,285 g. One patient had the associated anomaly of intestinal atresia and short bowel. Rupture of the intestines during delivery was noted in one patient. The authors applied their nonaggressive staged repair using a prosthetic silo with preservation of the umbilical cord in 20 of the 24 cases (83.3%). Primary closure with preservation of the umbilical cord was performed in the remaining four cases (16.7%). In these patients, the gastroschisis was mild.


RESULTS
In the 20 cases treated by staged repair, the average interval between the first and second operation was 9.8 days. Mechanical ventilation was not required in 16 of 20 (80%) patients treated by staged repair, or in two of four (50%) patients treated by primary repair. The number of days to the first feeding averaged 14.6 days in 23 cases, excluding the patient with short bowel syndrome who required continuous total parenteral nutrition (TPN). TPN through a central venous catheter was required in 3 of 23 patients (13.0%). The overall average hospital stay was 55.1 days. Survival was 24 of 24 or 100%. Complications included perforation of the intestines, gastric bleeding, ventral hernia, and wound infection. No infections were associated with the prosthetic silo. All of the patients had a satisfactory cosmetic outcome. Recent advances in neonatal intensive care, including antibiotic therapy, reduced the possibility of infection.


CONCLUSIONS
This staged repair of gastroschisis was simple and safe, neither requiring experienced surgical judgment nor complicated postoperative management, and achieved satisfactory results. Furthermore, preservation of the umbilical cord provided an improved cosmetic appearance.
