Objective
To characterize the presentation, management and outcomes of infants with necrotizing enterocolitis totalis (
t
NEC) vs surgical non-totalis NEC (
s
NEC).
Study design
This retrospective study identified infants undergoing surgery for NEC through The Children’s Hospitals Neonatal Database. Demographic, surgical and mortality characteristics were compared.
Results
Of 1059 infants, 161 (15.2%) had
t
NEC. Perinatal characteristics did not differ.
t
NEC infants were older and were less likely to have pneumoperitoneum at referral (5.6% vs 13.1%,
p
< 0.001) or intestinal perforation at surgery (38.5% vs 66.7%,
p
< 0.001). Infants with
t
NEC were more acidotic preoperatively (7.1, [IQR 7, 7.3] vs 7.3, [IQR 7.2, 7.4],
p
< 0.001). Mortality was 96.9% for
t
NEC and 26.5% for
s
NEC (
p
< 0.001).
t
NEC cases varied by center, accounting for 0–43% of all surgical NEC cases.
Conclusions
Mortality is high for
t
NEC infants, who present at older age, with greater illness severity but are less likely to have intestinal perforation than
s
NEC infants.
