Barium Appendicitis 6 Weeks After Upper Gastrointestinal Imaging

Area of Science:

• Radiology
• Pediatric Surgery
• Gastroenterology

Background:

• Barium sulfate is a common contrast agent for upper gastrointestinal imaging (UGI).
• Retention of barium in the appendix can form a barolith, potentially leading to appendicitis.
• Barium-associated appendicitis is a rare but serious complication, particularly in pediatric patients.

Observation:

• An 8-year-old girl developed acute appendicitis secondary to a barolith.
• The patient underwent a laparoscopic appendectomy six weeks after UGI procedures.
• This case highlights the risk of barium retention causing appendicitis in children.

Findings:

• Barium sulfate can act as an appendicolith, causing obstruction and inflammation.
• Prompt diagnosis and surgical intervention (laparoscopic appendectomy) are effective treatments.
• Early recognition of baroliths is key to preventing complications.

Implications:

• Patients undergoing UGI imaging should be informed about the potential risk of barium retention in the appendix.
• Clinicians should maintain a high index of suspicion for barium-associated appendicitis in pediatric patients presenting with appendicitis symptoms.
• Awareness and early intervention can mitigate the risk of severe outcomes and ensure successful treatment.
