Is Early Delivery for Gastroschisis Beneficial?

image_pdfFavoriteLoadingFavorite

BACKGROUND AND PURPOSE:

  • Shamshirsaz et al. (Ultrasound in Obstetrics & Gynecology, 2019) assessed whether elective preterm delivery at 34 weeks for gastroschisis to limit bowel exposure to amniotic fluid was of benefit compared with routine obstetric care

METHODS:

  • Randomized controlled trial (RCT)
  • Participants
    • Sonographic diagnosis of fetal gastroschisis
    • Referred <34 weeks
  • Exposures
    • Early delivery
      • Induction of labor at 34 weeks
    • Routine care (standardized protocol)
      • From 32 weeks: Fetal assessment weekly or twice a weekly
      • Delivery by 37 to 38 weeks
  • Primary outcome
    • Length of time on total parenteral nutrition (TPN)
  • Secondary outcomes
    • Time to closure of gastroschisis
    • Length of stay in hospital
  • Data analysis was based on intention-to-treat
    • For 90% power, total sample size of 86 patients (43 in each arm) would be needed to demonstrate a 7 day reduction in the time on TPN from the historic control of 25 days

RESULTS:

  • 10 women in early delivery group | 11 in routine care group
    • Trial stopped early at the first planned interim analysis due to patient safety concerns and for futility
  • Median gestational age at delivery:
    • Early delivery: 34.3 weeks
    • Routine care: 36.7 weeks
  • Primary outcome: There were no differences between neonates of women who underwent early delivery vs routine care
    • Median number of days on TPN (P = 0.08)
      • Early delivery: 54 days
      • Routine care: 21 days
    • Length of stay in hospital (P = 0.15)
      • Early delivery: 70.5 days
      • Routine care: 31 days
  • Neonates in the early delivery group experienced more late-onset sepsis vs the routine care group (P = 0.03)
    • Early delivery: 40%
    • Routine delivery: 0%

CONCLUSION:

  • There is no benefit to early delivery for fetuses with gastroschisis compared to routine care
  • The study needed to be terminated early because evidence pointed to harmful effects of early delivery vs routine care for prenatally identified gastroschisis
