Small bowel obstruction (SBO) after congenital diaphragmatic hernia (CDH) repair is common, often requiring surgery. Higher illness acuity, including ECMO and additional abdominal surgeries, increases SBO risk.
Area of Science:
- Pediatric Surgery
- Gastroenterology
- Neonatology
Background:
- Small bowel obstruction (SBO) is a significant complication post-congenital diaphragmatic hernia (CDH) repair.
- SBO can lead to increased morbidity and mortality in affected neonates.
Purpose of the Study:
- To determine the incidence of SBO following CDH repair.
- To identify risk factors associated with SBO development after CDH repair.
Main Methods:
- Retrospective review of 120 CDH patients from January 2010 to September 2022.
- Analysis of risk factors including operative approach, repair type, ECMO, and additional abdominal surgeries (gastrostomy tube, fundoplication).
Main Results:
- 16% of patients developed SBO, primarily due to adhesive bands (94%).
- Need for ECMO, prior gastrostomy tube, prior fundoplication, longer time to CDH repair, and longer initial hospitalization were significant risk factors.
- 94% of SBO cases required surgical intervention.
Conclusions:
- Neonates with higher illness acuity (ECMO, additional surgeries, prolonged hospitalization/repair time) face increased risk of adhesive SBO post-CDH repair.
- SBO following CDH repair frequently necessitates surgical management.

Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...
Esophageal Strictures-I: Introduction
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
