Retained capsule endoscopy causing intestinal obstruction - Endoscopic retrieval by retrograde single-balloon enteroscopy.

Capsule endoscopy (CE) has revolutionized the investigation of gastrointestinal tract disease and is a safe device. Capsule retention is the most common complication occurring in 1.4% of the procedures. Patients with pre-existing conditions such as Crohn’s disease (CD), have a higher retention rate at 2.6%. The retained capsule can be excreted spontaneously or after drug stimulation in a few cases, but the majority will need to be removed by surgical or endoscopic intervention including double-balloon enteroscopy (DBE). This report presents a case of successful removal of retained CE causing intestinal obstruction by retrograde single-balloon enteroscopy (SBE) in a patient with CD.
