Objective:To determine an optimal route of delivery for fetuses with prenat
ally diagnosed omphalocele. Data source: MEDLINE(C)search of years 1966-199
6. Results: Descriptive retrospective analyses do not support the idea that
cesarean delivery of fetuses with omphalocele is associated with an improv
ed survival rate. However, most of those studies do not control for confoun
ding variables like type and severity of associated anomalies, omphalocele
size, prematurity rate, presence of trial of vaginal delivery, rate of intr
apartum sac rupture, tertiary treatment centers accessibility, time and typ
e of surgical correction, and postoperative morbidity. There is no evidence
that vaginal delivery is safer than cesarean for fetuses with isolated sma
ll omphalocele. Fetuses with giant (>5 cm) omphalocele should be delivered
by cesarean section. Vaginal delivery at term is offered for fetuses with c
oexisting life-threatening anomalies. Conclusions: We propose that until ra
ndomized trial of vaginal and cesarean delivery for fetal omphalocele is av
ailable, the preferred mode of delivery would be the vaginal route as that
is safer for the mother. (C) 1999 Elsevier Science Ireland Ltd. All rights
