Neonatal small bowel atresia, stenosis and segmental dilatation

Area of Science:

• Pediatric Surgery
• Gastrointestinal Surgery
• Neonatal Care

Background:

• Small bowel atresia, stenosis, and segmental dilatation are congenital conditions requiring surgical intervention in neonates.
• These conditions can present as single or multiple sites of intestinal obstruction.
• Associated gastrointestinal abnormalities are common in affected infants.

Purpose of the Study:

• To evaluate the surgical outcomes and long-term complications in neonates treated for small bowel atresia, stenosis, or segmental dilatation.
• To compare complication rates between primary anastomosis and staged procedures for intestinal obstruction.

Main Methods:

• Retrospective analysis of 44 neonates treated over 8 years by a single surgical team.
• Surgical approaches included resection with primary anastomosis and staged procedures for complicated lesions.
• Data collected on lesion type, associated anomalies, surgical method, complications, and survival rates.

Main Results:

• 44 neonates underwent surgery for small bowel atresia, stenosis, or segmental dilatation.
• 34 infants had primary anastomosis, while 10 required staged procedures.
• Staged procedures had a higher complication rate (60%) compared to primary repair (32.4%).
• Overall initial survival was 93%, reaching 100% in cases without associated anomalies or prenatal complications.
• 27% of survivors developed long-term disabilities.

Conclusions:

• Primary anastomosis is associated with a lower complication rate for small bowel atresia compared to staged procedures.
• While initial survival rates are high, long-term disabilities are a significant concern for survivors of neonatal intestinal obstruction.
• Further research into mitigating long-term sequelae is warranted.
