Insights
Antegrade intussusceptions around gastrojejunostomy tubes can be diagnosed using sonography and fluoroscopy. These imaging techniques also guide successful reduction of the intussusception.
Area of Science:
- Gastroenterology
- Radiology
- Medical Imaging
Background:
- Gastrojejunostomy tubes are used for enteral feeding and decompression.
- Intussusception, a telescoping of the bowel, can occur around these tubes.
- Diagnosis and management of this complication are crucial.
Purpose of the Study:
- To describe antegrade intussusceptions of the duodenum and jejunum occurring around gastrojejunostomy tubes.
- To highlight the role of sonography and fluoroscopic contrast tube studies in diagnosis.
- To present methods for intussusception reduction.
Main Methods:
- Review of sonography and fluoroscopic contrast tube studies in patients with gastrojejunostomy tubes.
- Description of intussusception imaging findings.
- Techniques for reduction including air or contrast injection and wire exchange.
Main Results:
- Antegrade intussusceptions of the duodenum and jejunum were identified around gastrojejunostomy tubes.
- Successful reduction was achieved via bolus injection of air or contrast medium through the tube.
- Exchange over a wire was also an effective reduction method.
Conclusions:
- Sonography is effective in diagnosing intussusception around gastrojejunostomy tubes.
- Fluoroscopic contrast tube studies are valuable for diagnosing this condition.
- These imaging modalities aid in the management of gastrojejunostomy tube-related intussusception.
Objective:
We describe antegrade intussusceptions of duodenum and jejunum around gastrojejunostomy tubes seen on sonography and fluoroscopic contrast tube studies. Reduction of the intussusception was achieved by bolus injection of air or contrast medium through the tube or exchange over a wire.
Conclusion:
Sonography and fluoroscopic contrast tube studies permit diagnosis of intussusception around gastrojejunostomy tubes.
