Endoscopic approach to capsule endoscope retention

In recent years, wireless capsule endoscopy has become increasingly indicated and utilized in the diagnosis and management of small bowel disorders. As such, its most common complication, capsule retention, has become a more frequently encountered clinical entity. Historically, when medical management of capsule retention has failed, patients have been sent directly to surgery. However, recent advances in small bowel enteroscopy have demonstrated a high success rate and safety profile in retrieving retained capsules. These approaches appear to be a viable alternative to surgery in many clinical scenarios. This article discusses both standard and advanced endoscopic approaches to capsule retention, and presents an algorithmic approach to their utilization.
