Outcomes of a Physician-Controlled Wire-Guided Cannulation of the Bile Duct Using a Novel Sphincterotome: A Single-Center, Prospective Study

Figure 1. (a) CleverCut3V Short Bend Tip with a tip length of 2 mm and a cutting wire length of 15 mm. (b) The tip can be bowed compactly.
Figure 2.
Figure 2. The proportion of final SBDC success was 97.5% (n = 39). The final SBDC techniques used in 10 patients with failed PCWGC were contrast injection method (n = 6), PGP (n = 1), and precutting (n = 3).
