Analysis of bowel perforation in necrotizing enterocolitis
Pediatric Radiology
|January 1, 1987
Summary
Necrotizing enterocolitis (NEC) perforation is often missed on imaging. Paracentesis is crucial for diagnosing NEC perforation when imaging is unclear, especially in neonates with ascites or peritonitis.
Area of Science:
- Neonatal Medicine
- Pediatric Surgery
- Radiology
Background:
- Necrotizing enterocolitis (NEC) is a severe gastrointestinal condition in neonates.
- Bowel perforation is the most critical complication of NEC, leading to high mortality.
- Accurate and timely diagnosis of NEC perforation is essential for improving outcomes.
Purpose of the Study:
- To evaluate the diagnostic accuracy of radiographic criteria for NEC-related bowel perforation.
- To determine the necessity of paracentesis in diagnosing NEC perforation.
- To identify key factors influencing NEC perforation, including timing and location.
Main Methods:
- Retrospective review of 155 NEC cases over 5.5 years.
- Analysis of surgical findings, autopsy results, and radiographs in 19 cases of NEC perforation.
- Assessment of radiographic evidence (free air, ascites) and clinical indicators.
Main Results:
- Only 63% of NEC perforations showed radiographic evidence of free air.
- 21% had ascites without pneumoperitoneum, and 16% had neither.
- Perforations often occurred within 30 hours of diagnosis, predominantly in the ileo-cecal region (58% of cases).
Conclusions:
- Radiographic criteria alone are imprecise for diagnosing NEC bowel perforation.
- Paracentesis is mandatory for NEC patients with ascites or clinical signs of peritonitis.
- Understanding perforation timing and ileo-cecal region involvement aids in management.
