[Current status and clinical progress of capsule retention]

Area of Science:

• Gastroenterology
• Medical Devices
• Diagnostic Imaging

Background:

• Small bowel capsule endoscopy is a key tool for diagnosing obscure gastrointestinal bleeding and unexplained abdominal pain.
• Capsule retention is a known complication, occurring in 1-2% of procedures, particularly in Crohn's disease and small bowel tumor detection.
• While often asymptomatic, retention can rarely lead to intestinal obstruction or perforation, necessitating intervention.

Purpose of the Study:

• To evaluate the role and effectiveness of the patency capsule in preventing capsule retention.
• To highlight the importance of managing capsule retention risks in small bowel capsule endoscopy.

Main Methods:

• Review of current literature and clinical practices regarding small bowel capsule endoscopy.
• Analysis of the incidence and management strategies for capsule retention.
• Assessment of the patency capsule as a risk mitigation tool.

Main Results:

• Capsule retention is a significant concern in small bowel capsule endoscopy, with specific patient groups at higher risk.
• Conservative, endoscopic, and surgical interventions are available for managing retained capsules.
• The patency capsule has emerged as a novel method to proactively reduce the risk of capsule retention.

Conclusions:

• Small bowel capsule endoscopy is invaluable for diagnosing small bowel pathologies.
• Proactive measures, such as using a patency capsule, are crucial for patient safety and improving the overall utility of capsule endoscopy.
• Minimizing capsule retention enhances the diagnostic yield and patient experience in small bowel capsule endoscopy.
