We performed capsule endoscopy for a patient with immune checkpoint inhibitor-induced enteritis and found multiple erosions or small ulcers in the small intestine. No reports demonstrated the effectiveness of capsule endoscopy for immune checkpoint inhibitor-induced gastrointestinal adverse events, and our case suggests that capsule endoscopy may be useful to evaluate immune checkpoint inhibitor-induced enteritis.
Keywords: capsule endoscopy; immune‐related adverse event; intestinal disorder.
