Safety and Accuracy of Suction Rectal Biopsy in Preterm Infants

Abstract

Purpose: Little attention were paid in the diagnosis of preterm infants with Hirschsprung disease (HD) in most pediatric surgeons. We aimed to explore the safety and accuracy of suction rectal biopsy (SRB) in preterm infants.Methods: A retrospective review was conducted on 45 preterm patients who underwent SRB from 2015 to 2019 in our hospital. We collected the clinical characteristics and pathology results of the patients, and followed up. The sensitivity and specificity of SRB for HD diagnosis were calculated.Results: The median gestational age of the patients was 35 weeks (range: 28.9 to 36.9 weeks) while the median gestational age at biopsy was 38.6 weeks (range: 33.4 to 60.0 weeks), and the median weight was 2790 g (range: 1580 to 4100 g). Fifteen cases (33.3%) were positive for HD which were confirmed after the pull-through surgery. The ganglion cells presented on 30 cases. And the diagnosis of HD was excluded in 29 patients after discharge follow-up. The sensitivity was supposed to be 93.7%-100% and specificity was 100%. Among the patients whose biopsy age is < 37 weeks (10 cases) or biopsy weight is < 2000 g (5 cases), no complications occurred after SRB.Conclusion: SRB is safe and accurate in late preterm infants.

A two-center retrospective study: association of early caffeine administration and oxygen radical diseases in neonatology in Chinese preterm neonates

“…However, in our study, we did not observe a significant difference in the gross incidence of PVL or in subgroups between the early and late caffeine treatment groups. This finding is consistent with a retrospective study reported by Yang et al (18).…”
