Objective:   We aimed to assess the usefulness of a novel guide-wire technique for repositioning without the use of a Nelaton tube and to compare this to the conventional technique.   Subjects and Methods:   A total of 50 patients who underwent endoscopic nasobiliary drainage (ENBD) at the Yachiyo Medical Center, Chiba, Japan, were enrolled into the study. The patients were randomly divided into 2 groups according to the use of a novel guide-wire technique (n = 28) or the conventional technique (n = 22). The ENBD catheters were repositioned from the mouth to the nose. The primary end point was the procedural time from the insertion of the Nelaton tube or guide wire into the nostril until the ENBD catheter had been repositioned in the nose. The secondary end point was the success rate of the procedure.   Results:   The mean procedure time of our technique (120.8 s) was shorter than the traditional technique (131.9 s), but this difference was not statistically significant (p = 0.56). Our technique did not involve the use of the Nelaton tube, and so could save the cost of USD 1.17 per patient. The novel technique did not require the removal of the mouthpiece with a laryngoscope or the use of a Nelaton tube, and no postural change was necessary. A single operator performed the novel procedure unassisted. No adverse events were observed relating to either the novel or the traditional technique.   Conclusions:   The novel guide-wire technique for repositioning ENBD catheters was effective and is recommended for use.
