“…Four recent RCTs comparing different types of guidewire or techniques of cannulation found no differences in AE rates, particularly for PEP [177 -180]. In one of these RCTs, higher rates of successful cannulation were obtained with guidewires with highly flexible tips [178].…”

Main Recommendations Prophylaxis 1 ESGE recommends routine rectal administration of 100 mg of diclofenac or indomethacin immediately before endoscopic retrograde cholangiopancreatography (ERCP) in all patients without contraindications to nonsteroidal anti-inflammatory drug administration.Strong recommendation, moderate quality evidence. 2 ESGE recommends prophylactic pancreatic stenting in selected patients at high risk for post-ERCP pancreatitis (inadvertent guidewire insertion/opacification of the pancreatic duct, double-guidewire cannulation).Strong recommendation, moderate quality evidence. 3 ESGE suggests against routine endoscopic biliary sphincterotomy before the insertion of a single plastic stent or an uncovered/partially covered self-expandable metal stent for relief of biliary obstruction.Weak recommendation, moderate quality evidence. 4 ESGE recommends against the routine use of antibiotic prophylaxis before ERCP.Strong recommendation, moderate quality evidence. 5 ESGE suggests antibiotic prophylaxis before ERCP in the case of anticipated incomplete biliary drainage, for severely immunocompromised patients, and when performing cholangioscopy.Weak recommendation, moderate quality evidence. 6 ESGE suggests tests of coagulation are not routinely required prior to ERCP for patients who are not on anticoagulants and not jaundiced.Weak recommendation, low quality evidence. Treatment 7 ESGE suggests against salvage pancreatic stenting in patients with post-ERCP pancreatitis.Weak recommendation, low quality evidence. 8 ESGE suggests temporary placement of a biliary fully covered self-expandable metal stent for post-sphincterotomy bleeding refractory to standard hemostatic modalities.Weak recommendation, low quality evidence. 9 ESGE suggests to evaluate patients with post-ERCP cholangitis by abdominal ultrasonography or computed tomography (CT) scan and, in the absence of improvement with conservative therapy, to consider repeat ERCP. A bile sample should be collected for microbiological examination during repeat ERCP.Weak recommendation, low quality evidence.

“…Second, although the aim of the study was to evaluate how guidewires form a loop shape, the role of lubricity in each guidewire was not examined. In addition, the core wire constituting the guidewire, such as monofilament wires or monofilament wires covered with spiral coiled spring, might have influenced stricture penetration during cannulation [16]. Our experimental study did not account for this factor.…”

Background and study aims Duct penetration by the guidewire sometimes occurs during endoscopic retrograde cholangiography, which might lead to adverse events such as acute pancreatitis. To prevent duct penetration, making a loop shape with the guidewire might provide a useful technique. The aim of this experimental study was thus to evaluate which types of guidewire can most easily form a loop shape. Methods This experimental study evaluated six guidewires (0.025-inch, angle type): MICHISUJI; VisiGlide 2; Jagwire; Pathcorse; RevoWave-α UltraHard 2; and M-through. Flexibility of the tip, shaft stiffness, and the ability to form a loop were evaluated for each type in an ex vivo model. Deformation behavior was also recorded on video, and factors suitable for making a loop shape in each guidewire were evaluated. Results Flexibility and stiffness of each guidewire differed significantly. During an experimental study regrading deformation behavior before forming a loop shape, maximum load was lower for MICHISUJI (6.8 g) than for other guidewires (Jagwire [11.3 g], M-through [12.9 g], VisiGlide 2 [12.9 g], Revowave [21 g], and Pathcorse [25.4 g]). Mean time required to achieve a loop shape was as follows: MICHISUJI, 6.2 seconds; M-through, 8.7 seconds; VisiGlide 2, 11.0 seconds; and Revowave, 7.1 seconds. Conclusion In conclusion, characteristics of flexibility and stiffness among guidewires were significantly different in the ex-vivo study. In the experimental study regrading deformation behavior until achieving a loop shape, maximum load also differed. To evaluate whether guidewires easily form a loop shape, clinical study is needed.

“…The most important part of the guidewire configuration for biliary cannulation is the tip, and the new products are mainly focused on this part. 10,11 However, in order to ensure an objective evaluation, we believe that the research method should be more elaborate. More accurate results could be obtained if the research were conducted separately for each tip' s core material, coating, and shape, even for the same products.…”

Background/Aims: Using an appropriate guidewire can increase the success rate of selective cannulation in endoscopic retrograde cholangiopancreatography. The purpose of this technical study was to investigate the characteristics of each guidewire type and to evaluate its efficiency and rapidity of insertion. Methods: We conducted a three-point bending test using a universal testing machine to investigate the flexibility and bending features of each guidewire. 3D-printed silicone tubes with various types of stricture and a handmade biliary tree silicone model with sixstranded intrahepatic ducts were used to evaluate the success rate and insertion time of each guidewire. Results: In the three-point bending test, the characteristics of each guidewire were classified. We found that the bending strengths and times were independent of shaft thickness. Using two in vitro biliary duct models, we determined that the success rate and total insertion time were better for guidewires with a resilient shaft and angled tip than for other types of guidewires (p<0.001). Although thickness of the guidewire affected the success rate (p<0.05), it did not affect the total insertion time (p≥0.05). Conclusions: Among several types of guidewire, some factors (resilient shaft, highly flexible, and angled tip) appeared to be associated with the efficiency and rapidity of the guidewire insertion.
