Capsule endoscopy device retention and magnetic resonance imaging

Area of Science:

• Gastroenterology
• Radiology
• Medical Device Safety

Background:

• Capsule endoscopy is a valuable tool for visualizing the gastrointestinal tract.
• Device retention is a known complication of capsule endoscopy, occurring in 1-1.7% of procedures.
• Retained capsule devices pose a significant safety risk, particularly in relation to magnetic resonance imaging (MRI).

Purpose of the Study:

• To report a unique case of a retained capsule endoscopy device.
• To emphasize the potential dangers of retained devices during MRI examinations.
• To highlight the importance of device retrieval and MRI contraindications.

Main Methods:

• A 55-year-old male patient underwent capsule endoscopy for an undiagnosed bleed.
• Diagnostic imaging, including abdominal radiography and MRI, was performed.
• Clinical presentation and diagnostic findings were reviewed.

Main Results:

• Capsule endoscopy revealed a retained capsule in a colonic diverticulum.
• The retained capsule was incidentally detected during an MRI scan for unrelated lumbar radiculopathy.
• The MRI was immediately terminated upon identification of the retained capsule, preventing potential harm.

Conclusions:

• Retained capsule endoscopy devices are a contraindication for MRI due to safety concerns.
• Incidental discovery of retained devices during imaging underscores the need for careful patient selection and device management.
• Awareness of capsule retention risks is crucial for patient safety in diagnostic procedures.
