Physician-Controlled Wire-Guided Cannulation of the Minor Papilla

Figure 1

Cannulation technique: (a) a pull-type sphincterotome loaded with a 0.035^′′ guidewire is positioned adjacent to the minor papilla (arrow). (b) The wire is used to cannulate the papillary os. (c) The wire is advanced 20 mm, achieving superficial wire cannulation. (d, e) The sphincterotome is lightly impacted on the minor papilla and a dorsal pancreatogram is then obtained. (f, g) Deep wire and device cannulation are attained and more robust dorsal ductography is performed.
