EGD: Esophagogastroduodenoscopy; AXR: Abdominal X-ray; MRI: Magnetic resonance imaging; CE: Capsule endoscopy; CTE: CT enterography; SBFT: Small bowel follow-through; US: Ultrasound; CD: Crohn’s disease. (±): Suspected positive; (+): Positive; (-): Negative; Not pass: The capsule did not pass the ileocecal valve within the duration of the examination, but was not retained. GI: Gastrointestinal.

¹The patient was lost to follow-up 1 mo after surgery.

²The follow-up was missed after CE examination.
