Laparotomy versus peritoneal drainage for necrotizing enterocolitis and perforation.

Area of Science:

• Neonatal surgery
• Pediatric gastroenterology
• Critical care medicine

Background:

• Perforated necrotizing enterocolitis (NEC) is a severe condition in premature infants, leading to significant morbidity and mortality.
• The optimal surgical management for perforated NEC remains uncertain, prompting comparative studies.

Purpose of the Study:

• To compare the outcomes of primary peritoneal drainage versus laparotomy with bowel resection in preterm infants diagnosed with perforated necrotizing enterocolitis.
• To evaluate the impact of surgical approach on survival, parenteral nutrition dependence, and hospital stay.

Main Methods:

• A multicenter randomized trial involving 117 preterm infants (gestational age <34 weeks, birth weight <1500 g) with perforated NEC.
• Infants were assigned to either primary peritoneal drainage or laparotomy with bowel resection.
• Primary outcome was 90-day survival; secondary outcomes included 90-day dependence on parenteral nutrition and length of hospital stay.

Main Results:

• No significant difference in 90-day survival rates between primary peritoneal drainage (34.5%) and laparotomy (35.5%) groups (P=0.92).
• Similar rates of dependence on total parenteral nutrition at 90 days (47.2% vs. 40.0%, P=0.53) and comparable mean hospital stays for survivors (126 vs. 116 days, P=0.43).
• Subgroup analyses did not reveal a significant advantage for either treatment based on disease severity or gestational age.

Conclusions:

• The choice of surgical intervention (primary peritoneal drainage vs. laparotomy) does not influence survival or other key early clinical outcomes in preterm infants with perforated necrotizing enterocolitis.
• Findings suggest that current surgical options offer comparable results for this vulnerable patient population.
