Weight at Ostomy Takedown as a Factor to Consider for Operative Timing-Is It Relevant?

Weight thresholds have historically determined timing of enterostomy closure (EC) in premature neonates. Recent evidence suggests that neonates less than 2 kg (L2K) can safely undergo EC. We evaluate our single-center experience with performing EC in preterm neonates at L2K versus greater than 2 kg (G2K) at time of EC. A retrospective review of neonates who underwent EC from January 2018 to 2020 was performed. Neonates who were greater than 90 days at initial operation were excluded. Demographics, clinical characteristics including gestational age (GA) and birth weight (BW), operative reports, and outcomes were reviewed. We compared 30-day complications between neonates who underwent EC at L2K and G2K. We also compared time to full feeds (FF) and postoperative length of stay (LOS). Twenty-four neonates were included: 11 L2K and 13 G2K. The median GA and BW was 25.9 weeks (IQR 2.89) and 805 g (IQR 327), respectively. The most common intraoperative diagnosis during index operation was spontaneous perforation (70%), followed by necrotizing enterocolitis (8.69%). There were no significant differences in GA, BW, or diagnosis, between the L2K versus G2K cohort. We found no difference in complication rates, time to FF (12 days versus 10 days, P = .89), or postoperative LOS (31 days versus 36.5 days, P = .76) between patients who underwent EC at L2K versus G2K, respectively. Although weight gain may be an important indicator of perioperative nutrition status, this study shows that weight alone should not preclude otherwise appropriate patients from undergoing EC.
