Intestinal stricture in necrotizing enterocolitis
Insights
Infants surviving necrotizing enterocolitis (NEC) can develop intestinal strictures. These strictures, often found in the submucosa, may cause intestinal malfunction and require consideration in long-term infant care.
Area of Science:
- Pediatric Surgery
- Neonatal Medicine
- Gastroenterology
Background:
- Necrotizing enterocolitis (NEC) is a serious condition affecting premature infants.
- Intestinal strictures are a known complication following NEC.
- Understanding the incidence and characteristics of these strictures is crucial for patient outcomes.
Purpose of the Study:
- To investigate the incidence of intestinal strictures in infants who survived acute NEC.
- To analyze the relationship between treatment methods and stricture development.
- To evaluate the predictive value of initial radiographic findings for stricture formation.
Main Methods:
- Retrospective review of infants with NEC over a 3-year period.
- Inclusion of previously reported cases of intestinal stricture post-NEC from literature.
- Histological examination of stricture tissue.
Main Results:
- Eight of 43 NEC survivors developed intestinal strictures.
- Four infants had multiple strictures after diversion procedures; four had single strictures after medical therapy.
- Histology revealed wound healing, primarily in the submucosa; initial radiographs were not predictive.
Conclusions:
- Intestinal stricture is a significant complication in NEC survivors.
- Stricture should be considered in the differential diagnosis of intestinal dysfunction in these infants.
- Further research into prevention and management strategies is warranted.
Abstract:
In a 3-yr period, eight infants among 43 survivors of acute NEC developed intestinal stricture. Four infants developed multiple stricture after proximal diversion procedures, and four had single strictures after medical therapy. Nineteen cases of intestinal stricture after NEC were collected from the literature. Radiographic examinations at the time of the acute disease were not predictive of the risk of subsequent stricture. Histologic examination showed various stages of wound healing, most prominently in the submucosa. Stricture should be considered as the cause of intestinal malfunction in any child who survives acute NEC.
