The balloon-assisted enteroscope has been regarded as the standard device for direct visualization of deep small bowels and allows for the diagnosis and treatment of small bowel disease. At the beginning, its application was focused on the diagnosis of obscure gastrointestinal bleeding, inflammatory bowel disease, and small bowel tumor. However, the indications are being expanded to various therapeutic procedures, not only confined to bleeding control. With the expansion of the indications, the need to perform enteroscopy effectively and safely is increasing. Recent studies have been focused on the diagnostic yield, therapeutic yield, and long-term outcomes of the device. However, with the increasing number of procedures, procedural guidelines and quality indicators are also needed.
