The development of double-balloon enteroscopy enables us to diagnose various bleeding source, including Meckel diverticulum, in the small intestine. We herein report a case of bleeding Meckel diverticulum, diagnosed by double-balloon enteroscopy and treated successfully by laparoscopic surgery, and review of the literature.
