Value of the peroral pneumocolon in children
Insights
The peroral pneumocolon is a safe and effective imaging technique for pediatric patients. This method aids in diagnosing conditions like Crohn disease and Behçet syndrome when conventional barium studies are unclear.
Area of Science:
- Pediatric Radiology
- Gastrointestinal Imaging
Background:
- Conventional barium follow-through examinations can yield ambiguous results in pediatric patients.
- Accurate diagnosis of terminal ileum and cecum conditions is crucial for effective treatment.
Purpose of the Study:
- To evaluate the utility of peroral pneumocolon in pediatric patients with unclear barium study findings.
- To assess the diagnostic accuracy and tolerability of peroral pneumocolon in children.
Main Methods:
- A peroral pneumocolon study was performed on 13 pediatric patients with ambiguous results from 1188 conventional barium follow-through examinations.
- Air was insufflated rectally to visualize the terminal ileum and cecum.
Main Results:
- Peroral pneumocolon diagnosed terminal ileitis in six patients, confirming Crohn disease (5) and Behçet syndrome (1).
- It revealed more extensive disease in three patients and confidently excluded suspected fistulae in two.
- The procedure was well-tolerated and avoided more invasive interventions.
Conclusions:
- Peroral pneumocolon is a valuable diagnostic tool in pediatric radiology for evaluating the terminal ileum and cecum.
- It enhances diagnostic clarity when conventional barium studies are inconclusive.
- The technique is safe, well-tolerated, and can prevent the need for more invasive procedures in children.
Abstract:
This is the first study in children of the use of the peroral pneumocolon, which entails insufflation of air per rectum to examine the terminal ileum and cecum in conjunction with a conventional barium follow-through examination. Of 1188 conventional barium follow-through examinations performed during 2 1/2 years, results were ambiguous in 13 patients, who then underwent a peroral pneumocolon study. This study showed terminal ileitis in six patients, confirming the diagnosis of Crohn disease in five and Behçet syndrome in the other. In four patients peroral pneumocolon findings were normal. More extensive cecal or proximal ileal disease was shown in three patients by peroral pneumocolon, and fistulae suspected on conventional study were confidently excluded in two others. In all 13 the examination was well tolerated, and avoided further, more invasive procedures. The peroral pneumocolon is a useful procedure in children for these indications.
