“…The V-system was found to have both reduced rates of guidewire adjustments and time needed to complete accessory exchanges over a guidewire when compared to the traditional system. Reduction in exchange time between the V-system and the conventional system was 19.4 s versus 31.7 s (P < 0.001) [8] , whereas the need to reposition the guidewire was required less often with the V-system, 9.4% versus 35.7% (P = 0.0005) [8] . In contrast, the reduced procedure and fluoroscopy times were not found to be statistically significant [8] .…”

“…This is the first modification of a duodenoscope for facilitation of wire exchanges [8] . The V-system scope elevator lever includes a V-shaped g roove and an increased angle of articulation in comparison to the standard Olympus TJF-160 series endoscope.…”

“…The V-system scope elevator lever includes a V-shaped g roove and an increased angle of articulation in comparison to the standard Olympus TJF-160 series endoscope. This design promotes securing and locking of the short guidewire at the elevator level to reduce repositioning of the guidewire during accessor y exchanges [8] . The groove described above acts as the internal wire lock allowing use of a catheter without a short-wire track.…”

“…The ability of the V-scope to hold the Glidewire varied between exchanges regardless of endoscopic position, but still resulted in faster exchanges than a regular duodenoscope with no change in wire loss rates [16] . A prospective multicenter, randomized and controlled trial was conducted by Joyce et al [8] to compare the V-system (Olympus XTJF-140V2F) with the traditional duodenoscope and accessories. The V system scope elevator lever includes a V-shaped groove and an increased angle of articulation in comparison to the standard Olympus TJF-160.…”

Guidewires are routinely used at the time of endoscopic retrograde cholangiopancreatography (ERCP) to gain and maintain access to the desired duct and aid in the advancement of various devices. Limitations of the traditional long-wire systems have led to the introduction of three proprietary short-wire systems. These systems differ in many respects but share two main principles: They lock a shorter wire in position to allow advancement or removal of various devices without displacement of the wire and they all allow for physician control of the wire. In this comprehensive review, we describe the key features of the three currently available short-wire systems: RX, Fusion and V systems. We also focus on the potential benefits and drawbacks that accompany the short-wire concept as a whole and each specific system in particular. Although the available data are limited, it appears that the use of the short-wire systems lead to reduced procedure, fluoroscopy and device exchange times, decreased sedation requirements, improved wire stability and increased endoscopist control of the wire. Furthermore, the physician-controlled wire-guided cannulation has the potential to decrease ampullary trauma and the rate of post-ERCP pancreatitis. The short guidewire systems appear to be an improvement over the traditional long-wire systems but further studies directly comparing the two approaches are needed.
