New Designs in Balloon Enteroscopes
Double-balloon endoscopy (DBE) has been a significant advancement in the endoscopic diagnosis and treatment of small intestinal disorders. What makes the device particularly remarkable is not only its ability to perform deep enteroscopy, but also the fact that it has therapeutic capabilities as well. The new therapeutic EN-580T has improved intervention capability with a 3.2 mm accessory channel and improved image quality as well, despite maintaining the same outer diameter of 9.4 mm as the previous model. The new diagnostic EN-580XP has the same improved image quality as EN-580T despite having a much smaller outer diameter of 7.5 mm. These new enteroscopes are expected to improve clinical management as well as the research of small intestinal disorders. Double-balloon endoscopy for evaluation of the small intestine can also be performed in patients with surgically altered anatomy and difficult colons. A short EI-530B or EC-450BI5 scope is useful for ERCP in patients with a Roux-en-Y anastomosis and also in patients who have had prior difficult colonoscopies. Future technology may allow for automated insertion of the enteroscopes.
