Insights
Ultrasonography (US) reveals distinct jejunal intussusception findings in children, aiding prompt diagnosis. This imaging helps identify lead points and intussusception direction, preventing diagnostic delays.
Area of Science:
- Pediatric radiology
- Gastrointestinal imaging
- Abdominal ultrasonography
Background:
- Jejunal intussusception is a rare condition in children.
- Diagnosis can be challenging, often leading to delays in treatment.
- Ultrasonography plays a crucial role in identifying intussusception.
Purpose of the Study:
- To detail ultrasonographic findings in various jejunal intussusception types.
- To correlate imaging findings with underlying causes and intussusception direction.
- To evaluate the utility of ultrasonography in diagnosing jejunal intussusception.
Main Methods:
- Retrospective review of ultrasonography (US) findings in three pediatric patients.
- Cases included hamartomatous polyps causing antegrade and retrograde intussusception, and idiopathic postoperative intussusception.
- US findings guided subsequent diagnostic imaging and surgical planning.
Main Results:
- Ultrasonographic findings varied based on the cause and direction of intussusception.
- Hamartomatous polyps appeared as hyperechoic masses; a target lesion was noted in postoperative intussusception.
- US results facilitated timely further investigations like air enema or barium meal, leading to prompt surgery.
Conclusions:
- Ultrasonography is a valuable tool for diagnosing jejunal intussusception in children.
- Prompt US evaluation can prevent diagnostic delays and expedite appropriate management.
- Imaging findings guide selection of further gastrointestinal studies.
Objective:
To describe the ultrasonographic findings in different forms of jejunal intussusception in three children.
Patients And Method:
Two children with hamartomatous polyps of the jejunum acting as lead points for antegrade jejunoileocolic intussusception and retrograde jejunoduodenogastric intussusception respectively and one child with idiopathic postoperative intussusception were examined by ultrasonography.
Results:
The findings of the US studies were abnormal and different in each case, depending on the underlying condition and the direction (antegrade or retrograde) of the intussusception. The hamartomatous polyps were seen as hyperechoic solid masses but could not be diagnosed more specifically with US. A target lesion was found in the case of idiopathic postoperative intussusception. The US results prompted the next imaging procedure, air enema in the one patient in whom the intussusception had reached the colon and preoperative barium meal in all of the patients. Surgery was performed without the delay that usually occurs with jejunal intussusception.
Conclusion:
In the appropriate clinical setting, US should be used to look for jejunal intussusception, so that suitable diagnostic gastrointestinal studies can be performed and delay in diagnosis avoided.
