[Background/Objective] Therapeutic ERCP using short guidewires provides advantages in which the irradiation and performance time are minimized, and it can be performed within a small room by a fewer number of staff members, etc. However, ENBD cannot be performed with this system, so the creation of ENBD tubes that are compatible with short guidewires was therefore attempted. [Methods] A side hole was made in a tube so that it could be used for ENBD using a short guidewire. To investigate the durability of the side hole portion, holes were made in tubes of various sizes, after which traction experiments were conducted. Furthermore, to study the safety of the use of such a tube, this method was performed on 15 patients. [Results] The JIS criteria of tensile strength were sufficiently met with all of the sizes that were studied. No obstruction, dislodging, or damage of the tubes was observed in any of the patients, and this method could be performed without any problems associated with drainage or contrast. [Conclusion] Therapeutic ERCP using short guidewires is expected to be widely used in the future in Japan using these EN BD tubes.
