Cannulation Success

Abstract Background Selective biliary cannulation (SBC) is the first challenge of endoscopic retrograde cholangiopancreatography (ERCP), especially for trainees, and a rotatable sphincterotome may be useful to guide the directional axis of the scope and SBC. Methods We performed a prospective randomized single-center trial, enrolling 200 patients with a native papilla who required therapeutic biliary ERCP. Patients were randomly assigned to the rotatable sphincterotome group (n = 100) or the conventional sphincterotome group (n = 100). The primary endpoint was successful SBC by the trainees within 10 minutes. Results The early and late cannulation success rates did not differ significantly between the groups (P = 0.46 and P > 0.99, respectively). For the patients in whom trainees failed to achieve SBC, the rotatable sphincterotome was used as a rescue cannulation technique in four patients from the conventional group; in no patients in the rotatable group was the conventional sphincterotome used for SBC. Post-ERCP pancreatitis (PEP) occurred in 11 patients (5.5 %; 6 mild, 5 moderate); the incidence did not differ significantly between the two groups (rotatable group 3 %, conventional group 8 %; P = 0.21). The two groups were thus combined for evaluation of the factors relating to cannulation difficulty for trainees, which revealed that orientation of the papilla was a significant factor (P < 0.001). Conclusions The type of sphincterotome used did not affect the success of SBC by trainees. However, orientation of the papilla was revealed to be a significant factor relating to cannulation difficulty for trainees overall.

Background and Study Aims. The usefulness of wire-guided cannulation for avoiding hyperamylasemia and pancreatitis following endoscopic retrograde cholangiopancreatography (ERCP) is conflicting, and therefore we designed this study to determine whether wire-guided cannulation reduces the rate of post-ERCP hyperamylasemia and pancreatitis and compare its efficacy to conventional method. Patients and Methods. Seven hundred and forty-eight patients with hepatobiliary diseases consecutively underwent diagnostic or therapeutic ERCP at the unit of Taleghani referral hospital in Tehran. Among them, 546 patients were eligible for wire-guided cannulation and underwent this procedure and others underwent sphincterotome biliary cannulation using contrast injection as the conventional method. Results. Patients in the two groups were comparable in terms of gender and age. Successful biliary cannulation was achieved similary in the guidewire and conventional group (89.2% versus 86.4%) that in 5.4% and 14.1% of them it was difficultly performed, respectively (P=0.003). The main pancreatic duct was more visualized in 99.0% of patients in conventional group in comparison with 79.0% in another group (P<0.001). Multivariate regression analysis showed that wire-guided cannulation had a protective role for post-ERCP hyperamylasemia (OR: 0.336, 95% CI: 0.181–0.623, P<0.001). However, there were no significant differences between the two groups in rates of other procedure-related complications, such as, pancreatitis, bleeding, and perforation. Conclusion. The use of guidewire cannulation in comparison with conventional method can be accompanied with lower post-ERCP hyperamylasemia, and therefore selection of this cannulation technique especially in high-risk group is recommended.

Cannulation Success

Endoscopic retrograde cholangiopancreatography (ERCP) plays a significant role in the treatment of a vast array of pancreatobiliary diseases. However, despite significant progress in the optimisation of ERCP methods and accessories, the technical and clinical success of ERCP can vary significantly due to a variety of patient and operator factors. Over the past several decades, a number of advanced techniques have been developed to improve cannulation success rates, including the use of double-guidewire, pancreatic duct accessory-assisted, precut, and rendezvous techniques. Here, the authors provide an update and overview of the existing advanced techniques used in cases of difficult biliary cannulation, as well as the approach to their selection.

Abstract Background We investigated the utility and safety of a new uneven double-lumen sphincterotome in biliary cannulation in comparison with the conventional pancreatic guidewire (PGW) method. Methods We retrospectively evaluated 119 patients who required PGW placement because of difficult biliary cannulation. Endoscopic retrograde cholangiopancreatography (ERCP) was performed using a conventional ERCP catheter or a new uneven double-lumen sphincterotome. The success rate of bile duct cannulation, the operation time of bile duct cannulation, and the incidence of post-ERCP pancreatitis (PEP) were evaluated. Results Forty-four patients were treated with a new double-lumen sphincterotome (the new sphincterotome group) and 75 patients underwent conventional PGW placement (the conventional group). The success rate of bile duct cannulation was 39/44 (88.6%) in the new sphincterotome group and 63/75 (84.0%) in the conventional group (not significant). The total biliary cannulation time (from the reach to the papilla to the finish of biliary cannulation) was 16.0 (6.5–78) min in the new sphincterotome group and 26.0 (5–80) min in the conventional group (P < 0.01). The time from PGW placement to bile duct cannulation was 3.5 (0.3–57) min in the magictome group and 12.0 (1–65) min in the conventional group (P < 0.01). Hyperamylasemia was observed in 13/44 (29.5%) and 17/75 (22.7%), respectively (not significant). Five of 44 (11.3%) of the new sphincterotome group and 14/75 (18.7%) of the conventional group were diagnosed with PEP (not significant). Conclusion A new double-lumen sphincterotome allows selective bile duct cannulation to be performed in a shorter time than the conventional PGW method.

Cannulation Success Rate

Background. Several previous studies assessed the competence in endoscopic retrograde cholangiopancreatography (ERCP) using the bile duct cannulation success rate. However, the cannulation time is also important, because a long cannulation time was reported to be a risk factor for post-ERCP pancreatitis. Aim. To determine the number of ERCP procedures required for short cannulation time of the bile duct. Methods. We retrospectively analyzed 605 ERCP procedures performed for bile duct cannulation in patients with native papilla at our institution between March 2012 and December 2015. The successful procedures were divided into 2 groups: group L and group S (cannulation time>15 minutes and ≤15 minutes, resp.). An analysis of the relationship among the biliary cannulation time, ERCP experience, and other factors was then conducted. Results. Multivariate analysis showed that the ERCP experience of ≤300 procedures (odds ratio, 2.080; 95% confidence interval, 1.337–3.142; P=0.001) and malignant biliary stricture due to pancreatic cancer (odds ratio, 1.912; 95% confidence interval, 1.072–3.412; P=0.028) were found to be significantly associated with a cannulation time of >15 minutes. Conclusions. Our findings suggested that an ERCP experience of ≤300 procedures and malignant biliary stricture due to pancreatic cancer were associated with prolonged biliary cannulation time.

Abstract Background and study aims Findings in the literature are conflicting on whether trainee involvement in endoscopic retrograde cholangiopancreatography (ERCP) procedures is detrimental to cannulation success rates. We addressed this in a prospective study, where cannulation success with or without trainee presence was the primary outcome measure. Patients and methods We prospectively recorded data on 2 senior endoscopists and their trainees over an 18-month period for ERCPs in patients with a virgin ampulla. Presence or absence of a trainee at ERCP procedures was pragmatic, reflecting their other service or training commitments or annual leave. For trainee presence, the training protocol allowed them 6 minutes of supervised time in which to achieve biliary cannulation after reaching the ampulla. Study outcome measures included cannulation success, time to cannulation, technique, whether this was achieved independently by the trainee, and complications. Results There were 219 procedures recorded and analyzed (134 with a trainee, 85 without). Three trainees were involved. Selective biliary cannulation was achieved in 201 (92 %) of cases. When a trainee was present, cannulation was successful in 122/134 procedures (91 %), compared to 79/85 (93 %) with a senior endoscopist alone (P = 0.8, Fisher’s exact test). Mean time to biliary cannulation with a trainee present was 7 minutes, compared with 5 minutes with no trainee. Mean time for successful independent cannulation by the trainee was 4 minutes, and 9 minutes for a consultant following a trainee’s attempt. There were no serious adverse events. Conclusion Our study shows that with this training protocol, involvement of a trainee on a routine secondary care ERCP list does not impair biliary cannulation success, and does not prolong a subsequent attempt by the senior endoscopist if initially unsuccessful. These findings support the involvement of trainees in routine ERCP lists with this training protocol.

AbstractPeriampullary diverticula (PAD) have been encountered in 5.9 to 18.5% of patients during all the endoscopic retrograde cholangiopancreatography (ERCP). Cannulation in the presence of PAD can sometimes be difficult, time consuming, and often requires a higher level of endoscopic skills.Several techniques have been reported to facilitate and increase the chances of successful bile duct cannulation in the presence of PAD. The two-devices in one-channel method has been sparingly used. It involves the simultaneous use of a biopsy forceps and another instrument, either a cannula or sphincterotome through the same working channel. We successfully performed ERCP in three cases, where bile duct cannulation was performed in the setting of intradiverticular papilla using two-devices in one-channel method.We feel that the two-devices in one-channel method can be very useful and positioned higher up in the algorithm for successful cannulation in patients with PAD.

Difficult Biliary Cannulation

Background and study aim: In European Society of Gastrointestinal Endoscopy guidelines, biliary cannulation of naive papillae is defined as difficult in the presence of more than 5 papilla contacts, more than 5min cannulation time or more than one unintended pancreatic duct cannulation or opacification. It is not known whether cholecystectomy is a cause of difficult biliary cannulation. This study aimed to investigate whether cholecystectomy (CCY) is a cause of difficult biliary cannulation in patients who have undergone Endoscopic Retrograde Cholangiopancreatography (ERCP) for choledocholithiasis. Patients and methods: Adult patients with naive papillae and those who underwent ERCP for common bile duct stones and/or sludge were included in this retrospective study. Patient demographics, clinical presentation (acute cholangitis, biliary pancreatitis or biliary colic), periprocedural data including laboratory and radiological findings and ERCP results were compared between no-CCY and post-CCY groups. Results: 438 patients were included in the present study and 347 of these patients were in the no-CCY group and 91 patients were in post-CCY group. A statistically significant difference was found in the number of patients with difficult cannulation in the post-CCY group (n=30, 33.0%) patients compared to the no- CCY group (n=67, 19.3%) (p=0.011). According the multivariate analyses results, presence of history of cholecystectomy was found an independent risk factor of difficult cannulation (Odds ratio: 2.014; 95 % Cl 1.205-3.366; p=0.008). Conclusions: The results showed that biliary cannulation was significantly more difficult in patients with cholecystectomy who underwent ERCP for common bile duct stones.
