Necrotizing enterocolitis: late surgical results after enterostomy without resection

Area of Science:

• Pediatric Surgery
• Neonatal Care
• Gastroenterology

Background:

• Necrotizing enterocolitis (NEC) is a serious condition in neonates.
• Surgical intervention is often required for NEC, but optimal timing and approach remain debated.
• Previous approaches involved early resection of necrotic bowel.

Purpose of the Study:

• To evaluate the outcomes of delayed intestinal resection in neonates treated for NEC.
• To assess the efficacy of decompressive enterostomy without resection in the acute phase.
• To determine if delaying resection impacts bowel length preservation and long-term outcomes.

Main Methods:

• Retrospective review of 36 neonates treated for NEC between 1985 and 1992.
• Analysis of outcomes for conservative management versus surgical treatment.
• Detailed examination of 14 infants who underwent initial surgery with decompressive enterostomy and subsequent reintervention for intestinal continuity restoration.

Main Results:

• 18% mortality in conservatively treated NEC cases; 26% mortality in surgically treated cases.
• 14 of 17 survivors of initial surgery required reintervention 3-26 months later.
• Delayed resection after enterostomy led to spontaneous healing, preservation of bowel length, and minimal complications like short-gut syndrome.

Conclusions:

• Early resection of gangrenous bowel in NEC is not supported by this experience.
• A simple diverting enterostomy without resection in the acute phase is an effective initial surgical strategy.
• Delaying intestinal resection until recanalization allows for spontaneous healing and maximizes bowel length preservation.
