Patients with Crohnʼs disease may have multiple strictures of the small intestine, and surgical resection can lead to shortbowel syndrome. Endoscopic balloon dilation (EBD) is an alternative treatment to avoid surgical resection [1]; however, it is considered challenging to perform EBDs of multiple strictures. The calibrated small-caliber-tip transparent (CAST) hood (TOP Corporation, Tokyo, Japan) (▶Fig. 1) [2] makes it easier to insert a guidewire and a balloon catheter through a stricture. The CAST hood enables measurement of the strictureʼs inner diameter (▶Fig. 2), which is an important factor in choosing the appropriate size of balloon catheter for EBD. Although the passage through dilated strictures is frequently difficult, the CAST hood makes it easier to pass through post-EBD strictures. Therefore, the CAST hood makes it easier to perform EBDs of multiple strictures. Furthermore, endoscopic enteroclysis during double-balloon endoscopy (DBE) E-Videos
