Single balloon enteroscopy: Technical aspects and clinical applications

The small bowel has long been considered a black box for endoscopists because of its long length and the presence of multiple complex loop. Most of the small bowel is inaccessible by traditional endoscopic means. In addition, radiographic studies have significant limitations with regard to diagnostic yield, and surgery is an invasive alternative. This limitation was overcome through the development of balloon enteroscopy that becomes established throughout the world for diagnostic and therapeutic examinations of the small bowel. The single-balloon enteroscope (SBE) system (Olympus, Tokyo, Japan) was introduced into the commercial market in 2007. Several study demonstrated its efficacy and safety. Early reports on the use of singleballoon enteroscopy have suggested a high diagnostic yield and similar therapeutic potential to that of the double-balloon endoscope. SBE is viable technique for in the management of small bowel disease. Technically, it is easy to perform, may be efficient, and in the literature data available, seems to provide high diagnostic and therapeutic yield.
