Insights
A rare case of appendiceal knotting caused a strangulated closed-loop obstruction in a child. This unusual presentation of pediatric intestinal obstruction highlights the appendix
Area of Science:
- Pediatric Surgery
- Gastrointestinal Pathology
- Surgical Emergencies
Background:
- Intestinal obstruction is a common surgical emergency in children.
- Appendiceal abnormalities are rare causes of pediatric intestinal obstruction.
Observation:
- A 1-year 7-month-old boy presented with acute severe vomiting and abdominal pain.
- Barium enema showed a caecal mass and a 'bird's-beak' sign at the ileocaecal junction.
Findings:
- Surgery revealed an unusually long, necrotic appendix strangulating the terminal ileum.
- This resulted in a closed-loop obstruction without evidence of torsion.
Implications:
- This case represents the first documented instance of appendiceal knotting causing terminal ileum strangulation.
- Highlights the importance of considering rare appendiceal pathologies in pediatric intestinal obstruction.
Abstract:
A 1-year 7-month-old boy presented with sudden onset of severe vomiting and abdominal pain. Barium enema revealed the caecum was elevated by a mass and the ileocaecal junction was visualised with a very short segment of terminal ileum showing a 'bird's-beak' appearance. At surgery, an unusually long necrotic appendix knotting the terminal ileum resulted in strangulation of a segment of the terminal ileum. There was no evidence of torsion of the terminal ileum or appendix. To our knowledge, this is the first case of the appendix knotting the terminal ileum resulting in a strangulated closed-loop obstruction.
