[PMID: 34799254 DOI: 10.1016/j.hbpd.2021.11.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/17/2021] [Accepted: 10/20/2021] [Indexed: 02/05/2023]
Abstract
BACKGROUND European Society of Gastrointestinal Endoscopy (ESGE) recommends needle-knife fistulotomy (NKF) as the preferred precut technique in cases when standard cannulation techniques fail. Despite scarce scientific evidence, flat and diverticular papillae are thought not to be ideal for NKF, as they are associated with poor outcomes. The present study aimed to determine the outcomes of the use of NKF in relation to flat and intradiverticular papillae. METHODS This prospective multicenter study enrolled consecutive patients, evidencing naïve flat (group A, n = 49) or diverticular papilla (group B, n = 28), who underwent NKF after failure of standard cannulation techniques. Diverticular morphology was subdivided into intradiverticular (group B1, n = 14) and diverticular border papillae (group B2, n = 14), using a previously validated endoscopic classification of the major papilla. The success of biliary cannulation at initial endoscopic retrograde cholangiopancreatography (ERCP), overall biliary cannulation, overall cannulation time, and the rate of adverse events were assessed in the study. RESULTS The initial cannulation rates were 93.9%, 64.3% and 71.4% for group A, B1, and B2, respectively (P = 0.005); overall cannulation rates after a second ERCP were 98.0%, 92.9% and 85.7%, respectively (P = 0.134). Adverse events occurred in 11.7% of patients, with post-ERCP pancreatitis (PEP) being the most common adverse event (10.4%). Although there was a trend towards a higher incidence of PEP in flat papillae, univariate and multivariate analyses did not show any significant relationship between pancreatitis and trainee involvement, papillary morphology, nor overall cannulation time. CONCLUSIONS Although flat papillae are associated with high success rates of biliary cannulation using NKF, the rate of PEP is not negligible. NKF is feasible in diverticular papillae, but it is associated with a modest success rate in the initial ERCP.

Abstract
BACKGROUND A successful bile duct cannulation is a prerequisite for the realization of endoscopic retrograde cholangiopancreatography (ERCP). When biliary cannulation is not possible, needle-knife fistulotomy (NKF) can be performed. However, when biliary access is not successfully achieved even after performing NKF, it is possible to interrupt the procedure, and repeat the ERCP after a short interval. OBJECTIVE The aim of this study is to analyze if repeating an ERCP after a short interval of 48 hours is effective in achieving biliary access after an initial NKF was unsuccessfully performed. METHODS A total of 1024 patients with a naive papilla, that underwent ERCP between the years of 2009-2019, were retrospectively reviewed. Difficult biliary cannulation was identified in 238 of these cases and NKF was performed. Success of biliary cannulation, NKF success at the first and second ERCPs, the associations between the type of the papilla, biliary dilatation, and overall success of NKF and adverse events rates were evaluated. RESULTS Biliary access was initially achieved in 183 (76.8%) cases. Of the 55 (23.1%) remaining cases a second attempt was performed after 48 hours, and biliary access was successfully achieved in 46 (83.6%) of them. The overall success of NKF after the first and second ERCP, the success rate was 96.2%. Papilla located out of its normal position was related to a minor chance of success at NKF (P<0.05). CONCLUSION We conclude that when biliary access is not achieved after the performance of a NKF, a second attempt is safe and effective and should be attempted.

Abstract
BACKGROUND AND AIMS Needle-knife fistulotomy (NKF) has emerged as the preferred precut technique. From a late strategy, NKF has shifted to an early rescue technique and has been used recently as a primary method for biliary access. It is unknown how these changes have affected NKF outcomes. We analyzed the outcomes of NKF over time in a large cohort of patients. METHODS Multicenter retrospective cohort study of 842 patients who underwent NKF for biliary access between 2006 and 2019. Patients were divided into four study periods according to a late or early cannulation strategy and to the use of post-ERCP pancreatitis prophylaxis (Period 1-Period 4). We assessed outcomes of NKF, learning curves and shifts over time. RESULTS Bile duct access was obtained in 88.0% of the patients. The initial cannulation rate increased significantly from 77.5% in P1 to 92.0% in P4 (p < .001). An endoscopist can obtain 80% success rate after performing 100 NKF procedures (95% CI: 0.79-0.86) and a 95% success rate after 830 procedures (95% CI: 0.92-0.98). Adverse events and pancreatitis were observed in 6.5% and 4.9% of patients respectively. The rate of pancreatitis was not significantly different during the 4 periods (p = .190). A decline in the pancreatitis rate was observed from 2006 until 2016 (no trainees) and then an increase until 2019 (trainees involved). The presence of trainees increased the rate of pancreatitis in the last period by 9.9%. CONCLUSIONS The success of NKF has increased significantly over the years, initially in a rapid manner and then more slowly. It is associated with a low rate of complications, which tend to decrease with experience. The involvement of trainees is associated with an increased rate of pancreatitis.

Efficacy and safety of primary, early and late needle-knife fistulotomy for biliary access. Sci Rep 2021; 11:16658.

Abstract
European Society of Gastrointestinal Endoscopy recommends needle-knife fistulotomy (NKF) as the preferred precut technique. However, there is little information on whether NKF performed at different times is associated with different success and adverse event rates. We compared the outcomes of 3 different timings of NKF. This was an observational study conducted at 4 institutions and this was a retrospective analysis of prospectively collected data. We included 330 consecutive patients submitted to NKF attempt for biliary access. Patients were divided into three groups: NKF as an initial procedure for biliary access (group A, n = 121); early NKF defined as after 5 min, 5 attempts, or 2 pancreatic passages (group B, n = 99); and late NKF: after at least 10 min of unsuccessful standard biliary cannulation (group C, n = 110). We assessed the success rate of biliary cannulation at initial ERCP, time to perform NKF until biliary cannulation, overall biliary cannulation rate (second ERCP when initial failure), adverse event rate, and predictors of post-ERCP pancreatitis (PEP). The initial cannulation rate was 98%, 91% and 94% for groups A, B and C respectively, p = 0.08, whereas overall biliary cannulation rate was 100%, 95% and 98%, p = 0.115. The adverse event rate/PEP was 4.1%/2.5%, 7.1%/4% and 10.9%/8.2%, for groups A, B and C respectively, (p = 0.197 and p = 0.190). Median time for creating the fistula was A = 4.0 min, B = 3.2 min, and C = 5.6 min, p < 000.1. Each additional minute spent attempting cannulation increased the odds ratio (OR) for PEP by 1.072, and patients with 3 or more risk factors for pancreatitis had a higher chance of PEP. In conclusion, the timing of NFK does not appear to influence success rates but late NFK is associated with a higher time to create a fistula and an increased risk of pancreatitis. Primary NFK is associated with a high rate of success and a low rate of PEP and deserves additional investigation.

Influence of a novel classification of the papilla of Vater on the outcome of needle-knife fistulotomy for biliary cannulation. BMC Gastroenterol 2021; 21:147. [PMID: 33794778 PMCID: PMC8017832 DOI: 10.1186/s12876-021-01735-3] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/26/2020] [Accepted: 03/23/2021] [Indexed: 02/03/2023] Open
Abstract
Background Existing proposed classification systems for the Papilla of Vater (PV) suboptimally account for all relevant, encountered PV appearances, are too complex or have not been assessed for intra- or interobserver variability. We proposed a novel endoscopic classification system for PV, determined its inter- and intraobserver rates and used the classification system to assess whether the success and complications of needle-knife fistulotomy (NKF) are influenced by the morphology of the PV. Methods The classification system was developed by expert endoscopists. To evaluate the inter- and intraobserver agreement, an online questionnaire was sent to 20 endoscopists from several countries (10 experts and 10 nonexperts) that included 50 images of papillae of Vater divided among various categories. Four weeks later, a second survey, with the images from the first questionnaire randomly reordered, was sent to the same endoscopists. The inter- and intraobserver agreements among the experts and nonexperts was calculated. Using the proposed classification system, all 361 consecutive patients who underwent NKF for biliary access to a naïve papilla were prospectively enrolled in the study. Results The novel classification system comprises 7 categories: type I, flat type, lacking an oral protrusion; type IIA, prominent tubular nonpleated type, with an oral protrusion and < 1 transverse fold over the oral protrusion; type IIB, prominent tubular pleated type, with an oral protrusion and > 2 transverse folds over the oral protrusion; type IIC: prominent bulging type, with an enlarged and bulging oral protrusion; type IIIA, diverticular-intradiverticular type, with a papillary orifice inside the diverticulum; type IIIB: diverticular-diverticular border type, with a papillary orifice less than 2 cm from the diverticular border; type IV: unclassified papilla, with no morphology classified in the other categories. The interobserver agreement between experts was substantial (K = 0.611, 95% CI 0.498–0.709) and was higher than that between nonexperts (K = 0.516; 95% CI 0.410–0.636). The intraobserver agreement was substantial among both experts (K = 0,651; 95% CI 0.586–0.715) and nonexperts (K = 0.646, 95% CI 0.615–0.677). In a multivariate model, type IIIA and IIIB were the only independent risk factors for difficult rescue NKF biliary cannulation (P = 0.003 and P = 0.019, respectively), and type I and type IIB were the only independent risk factors for a prolonged cannulation time using NKF (P < 0.001 and P = 0.005, respectively). Conclusions The novel endoscopic classification system for PV is highly reproducible among experienced ERCPists according to the substantial level of agreement between experts. However, nonexperts require further training in its use. Using the novel classification system, we identified different types of papillae significantly associated with a lower efficacy of NKF and a prolonged time to obtain successful biliary cannulation using NKF.

Primary Needle-Knife Fistulotomy Versus Conventional Cannulation Method in a High-Risk Cohort of Post-Endoscopic Retrograde Cholangiopancreatography Pancreatitis. Am J Gastroenterol 2020; 115:616-624.

Abstract
OBJECTIVES Successful biliary cannulation is a prerequisite and important component of endoscopic retrograde cholangiopancreatography, but conventional cannulation methods (CCMs) have a postendoscopic retrograde cholangiopancreatography pancreatitis (PEP) rate of 14.1% in patients at high risk for PEP. The aim of this study was to evaluate the effectiveness and safety of needle-knife fistulotomy (NKF), compared with a CCM, when used for primary biliary access in patients at high risk for developing PEP. METHODS A total of 207 patients with one or more risk factors for PEP were prospectively enrolled. The patients were randomly allocated to one of 2 groups according to the primary biliary cannulation technique (NKF or CCM). We compared biliary cannulation success rates, cannulation and procedure times, and the incidence of adverse events, including PEP, between the groups. RESULTS The mean number of PEP risk factors was similar between the groups (NKF, 2.2 ± 1.0; CCM, 2.2 ± 0.9). PEP occurred in 8 patients in the CCM group and in no patients in the NKF group (9.2% vs 0%, P < 0.001). The rates of other adverse events did not differ between the groups. The biliary cannulation success rate was high in the NKF group, but relatively low in the CCM group, possibly because of the stringent failure criteria aimed at reducing PEP. However, the mean cannulation and total procedural times were longer in the NKF group than in the CCM group. DISCUSSION NKF is an effective and safe procedure to gain primary biliary access in patients at high risk for developing PEP. ClinicalTrials.gov, NCT02916199.

Abstract
The Japan Gastroenterological Endoscopy Society (JGES) has recently compiled guidelines for endoscopic sphincterotomy (EST) using evidence-based methods. Content regarding actual clinical practice, including detailed endoscopic procedures, instruments, device types and usage, has already been published by the JGES postgraduate education committee in May 2015 and, thus, in these guidelines we avoided duplicating such content as much as possible. The guidelines do not address pancreatic sphincterotomy, endoscopic papillary balloon dilation (EPBD), and endoscopic papillary large balloon dilation (EPLBD). The guidelines for EPLBD are planned to be developed separately. The evidence level in this field is often low and, in many instances, strong recommendation has to be determined on the basis of expert consensus. At this point in time, the guidelines are divided into six items including indications, techniques, specific cases, adverse events, outcomes, and postoperative follow up.

Abstract
BACKGROUND/AIMS The aim of this study was to assess the feasibility of needle-knife fistulotomy (NKF) as an initial procedure for biliary access in patients with stones in the common bile duct (CBD) who were at increased risk for post-ERCP pancreatitis (PEP). METHOD Fifty-five patients who underwent ERCP with NKF for CBD stones at our institution between July 2013, and May 2015, were prospectively enrolled in this study. They had one or more of the following risk factors for PEP: young age (<60 years), female sex, or normal CBD diameter (≤9 mm). The procedure was performed by an expert biliary endoscopist (S.J.). The success rate of biliary cannulation and CBD stone removal, and the incidence rate of adverse events were assessed. RESULTS Seventeen patients had 1 risk factor for PEP, 27 had 2, and 11 had 3. The median procedure times for NKF and CBD stone removal after NKF were 2.1 minutes (range, 0.2-8.7 min) and 6.5 minutes (range, 1.1-28.3 min), respectively. Success rates of CBD cannulation and stone removal using NKF were 96.3% (53/55) and 92.7% (51/55), respectively. None of the patients experienced PEP. Retroperitoneal duodenal perforation occurred in 1 patient (1.8%), but it was successfully treated by conservative management. CONCLUSION NKF might be feasible as an initial procedure for biliary access in patients with CBD stones who are at high risk for PEP if the procedure is performed by an expert biliary endoscopist.

Abstract
BACKGROUND AND AIMS Needle-knife papillotomy and fistulotomy (NKPF) is a new, modified technique designed for difficult biliary cannulation. The safety and efficacy of performing NKPF based on characteristics of main duodenal papilla (MDP) was evaluated. METHODS We performed a retrospective review of consecutive patients with intact papilla who were established as candidates for therapeutic ERCP at tertiary referral center. A total of 532 patients were included in conventional endoscopic retrograde cholangiopancreatography (ERCP) group in which repeated cannulation was tried in patients with difficult bile duct cannulation; and 598 patients enrolled in early NKPF group according to predefined parameters. Based on the characteristics of MDP, different types of NKPF were performed. The endoscopic data (mean procedure time, anatomy of the main papilla), rate of cannulation success, and post-ERCP complications were collected. RESULTS A total of 82 patients underwent NKPF. The mean procedure time of the small papilla group was longer than bulging papilla group (P < 0.05). The success rate of biliary cannulation in the small papilla group (69.3 %) was lower than in the bulging papilla group (100 %, P < 0.01). The overall successful biliary cannulation of patients in the NKPF group was significantly higher than in the conventional group (98.8 vs 90.8 %, P > 0.05). The total complication rate was 6.6 % among conventional group patients and 5.7 % among NKPF group, respectively. The overall complication rate and rates of specific complications (pancreatitis, bleeding, cholangitis, and perforation) in the two groups were similar (P > 0.05). CONCLUSION Early NKPF based on characteristics of MDP raised the success rate of biliary cannulation when conventional cannulation failed and did not increase the complication rate post-ERCP.

Abstract
In 1970, a Japanese group reported the first use of endoscopic retrograde cholangiopancreatography (ERCP), which is now carried out worldwide. Selective bile duct cannulation is a mandatory technique for diagnostic and therapeutic ERCP. Development of the endoscope and other devices has contributed to the extended use of ERCP, which has become a basic procedure to diagnose and treat pancreaticobiliary diseases. Various techniques related to selective bile duct cannulation have been widely applied. Although the classical contrast medium injection cannulation technique remains valuable, use of wire-guided cannulation has expanded since the early 2000s, and the technique is now widely carried out in the USA and Europe. Endoscopists must pay particular attention to a patient's condition and make an attendant choice about the most effective technique for selective bile duct cannulation. Some techniques have the potential to shorten procedure time and reduce the incidence of adverse events, particularly post-ERCP pancreatitis. However, a great deal of experience is required and endoscopists must be skilled in a variety of techniques. Although the development of the transpapillary biliary cannulation approach is remarkable, it is important to note that, to date, there have been no reports of transpapillary cannulation preventing post-ERCP pancreatitis. In the present article, selective bile duct cannulation techniques in the context of recent Japanese randomized controlled trials and cases of precut sphincterotomy are reviewed and discussed.

Abstract
OBJECTIVE. Although precut is considered an useful alternative when standard methods of biliary access have failed, there is some controversy about it's safety. The study aim was to evaluate the effectiveness of needle-knife fistulotomy (NKF) after a difficult biliary cannulation and whether common bile duct (CBD) diameter influenced complications. MATERIAL AND METHODS. Between November 2006 and December 2010, a total of 1087 consecutive patients with naive papilla were submitted to endoscopic retrograde cholangiopancreatography (ERCP) for biliary access, in an affiliated university hospital. If the biliary cannulation was unsuccessful after 12-15 min, a NKF was performed. The main outcomes were biliary cannulation rate, NKF success and post-ERCP complications. RESULTS. Biliary cannulation by standard methods was successful in 883 patients (81%). In the remaining 204 patients, NKF was performed and allowed CBD access in 166 (81%), leading to a 96% cannulation rate. A second ERCP was performed in 25 patients, with an NKF success of 90% and an overall biliary cannulation rate of 98%. The post-ERCP complication rate was 7.9% (n = 16) with a 6.4% pancreatitis rate and no deaths. The complication for patients with a CBD ≤ to 4 mm was 13.9% compared with 4.5% in the remaining patients (OR = 3.39, p = 0.024). CONCLUSIONS. NKF is a safe and highly useful method of accessing the CBD in the setting of a difficult biliary cannulation. Despite its safety profile, extra caution is needed when applying NKF to patients with thin bile ducts.

[PMID: 23877349 PMCID: PMC3840532 DOI: 10.1038/ajg.2013.217] [Citation(s) in RCA: 29] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/28/2012] [Accepted: 06/10/2013] [Indexed: 12/11/2022]
Abstract
OBJECTIVES In 2006, the American College of Gastroenterology (ACG)/the American Society for Gastrointestinal Endoscopy (ASGE) Taskforce on Quality in Endoscopy published quality indicators for the major gastrointestinal procedures. Our primary aim was to use the published literature to assess current endoscopic retrograde cholangiopancreatography (ERCP) intraprocedural performance and compare it to the targets set by the ACG/ASGE taskforce. Our secondary aim was to determine whether performance varies across different health-care settings (academic and community), study designs (prospective and retrospective), and trainee participation. METHODS A PubMed and EMBASE literature search from 1/1/2006 to 2/1/2013 was conducted. Articles were selected based on title, abstract, full text, and reporting of success rates for the intraprocedural quality indicators. Success rates, represented as numerical proportions, were collected from each study. For each success rate, a standard error and a 95% confidence interval (CI) was calculated. A random-effects meta-analysis model was used to weight each study, and a cumulative, weighted success rate (or effect size) for each indicator was determined. Random-effects meta-regression was then used to examine the impact of study setting, design, and trainee involvement on each quality indicator. RESULTS A total of 8,005 articles were initially retrieved. Following the application of predefined criteria, 52 articles remained. The cumulative, weighted bile duct cannulation success rate was 89.3% (95% CI 0.866-0.919); pancreatic duct cannulation was 85.0% (95% CI 0.813-0.886); precut utilization rate was 10.5% (95% CI 0.087-0.123); common bile duct stone extraction rate was 88.3% (95% CI 0.825-0.941); and the rate of successful biliary stenting below the common bile duct bifurcation was 97.5% (95% CI 0.967-0.984). Subgroup analysis with meta-regression showed no statistically significant differences between academic and community settings, prospective and retrospective study designs, and trainee participation on success across bile duct cannulation, precut utilization, and common bile duct stone extraction (insufficient observations/variance for pancreatic duct cannulation and biliary stent placement). CONCLUSIONS ERCP intraprocedural quality is in good standing. On the basis of this analysis, the two targets that could be potentially revised are precut utilization and biliary stenting. This analysis was confined to the published literature and therefore, in general, reflects the ERCP performance of institutions, primarily academic, that are conducting clinical research. Thus, it is difficult to generalize this performance assessment to the broader ERCP community as a whole.

Needle-knife precut papillotomy with a small incision over a pancreatic stent improves the success rate and reduces the complication rate in difficult biliary cannulations. JOURNAL OF HEPATO-BILIARY-PANCREATIC SCIENCES 2013; 20:382-8.

Abstract
BACKGROUND Successful precut sphincterotomy (PS) in difficult biliary cannulation (DBC) requires a large incision for deroofing the papilla. However, the high complication rate poses a substantial problem, in addition to the need for expert skills. Pancreatic stent placement could facilitate this procedure. Needle-knife precut papillotomy with a small incision using a layer-by-layer method over a pancreatic stent (NKPP-SIPS) could potentially improve the success rate and reduce the complication rate of PS. AIMS To validate the efficacy, feasibility and safety of NKPP-SIPS in DBC. METHODS Therapeutic endoscopic retrograde cholangiopancreatography with a naïve papilla was performed in 1619 cases between May 2004 and July 2011. We prospectively divided the patients chronologically, in terms of the period during which the procedure was performed, into two groups: group A; needle-knife precut papillotomy (NKPP) performed between April 2004 and October 2006; group B; NKPP-SIPS performed between November 2006 and July 2011. The success rates and complication rates were evaluated. NKPP was performed without pancreatic stent placement and the cut was made starting at the papillary orifice, extended upward over a length of more than 5-10 mm for deroofing the papilla. On the other hand, in NKPP-SIPS, a pancreatic stent was placed initially as a guide, and to prevent post-ERCP pancreatitis, the incision was begun at the papillary orifice in a layer-by-layer fashion and extended upward in 1-2 mm increments, not going beyond the oral protrusion, finally measuring less than 5 mm in length. RESULTS PS was performed in 8.3 % of the patients (134/1619). The cannulation success rate of PS in the entire group was 94.0 % (126/134). NKPP and NKPP-SIPS were performed in 36 and 98 of the patients, respectively. There was one case of major bleeding in group A, and no severe complications in group B. The success rates of bile duct cannulation increased from 86.1 % (31/36) in group A to 96.9 % (95/98) in group B (p = 0.0189). The overall complication rate of PS was YC 33 % (12/36) in group A (major bleeding 8.3 %; mild to moderate pancreatitis 19.4 %; perforation requiring surgery 2.8 %), and 7.1 % (7/98) in group B (mild to moderate pancreatitis 6.1 %; minor perforation 1 %) (p < 0.001). CONCLUSIONS NKPP-SIPS has significantly improved the success rate and reduced the complication rate of DBC, proving that a small incision starting at the orifice of the PS is sufficient, feasible and safe in DBC, when a pancreatic stent is inserted at the outset.

Abstract
AIM: To compare the efficacy, complications and post-procedural hyperamylasemia in endoscopic pre-cut conventional and needle knife sphincterotomie.
METHODS: We performed a retrospective analysis of two pre-cut sphincterotomy (PS) techniques, pre-cut conventional sphincterotomy (PCS), and pre-cut needle knife (PNK). The study included 143 patients; the classic technique was used in 59 patients (41.3%), and the needle knife technique was used in 84 patients (58.7%). We analyzed the efficacy of bile duct access, the need for a two-step procedure, the rates of complications and hyperamylasemia 4 h after the procedure, “endoscopic bleeding” and the need for bleeding control. Furthermore, to assess whether the anatomy of the Vater’s papilla, indications for the procedure or the need for additional procedures could inform the choice of the PS method, we evaluated the additive hyperamylasemia risk 4 h after the procedure with respect to the above mentioned variables.
RESULTS: The bile duct access efficacy with PNK and PCS was 100% and 96.6%, respectively, and the difference between the two groups was not significant (P = 0.06). However, the needle knife technique required two-step access significantly more often, in 48.8% vs 8.5% of cases (P < 0.0001). The only complication noted was post-ercp pancreatitis (PEP), which was observed in 4/84 (4.8%) and 2/59 (3.4%) patients submitted to PNK and PSC, respectively; the difference between the two procedures was not significant (P = 0.98). An analysis of other consequences of the techniques yielded the following results in the PNK and PCS groups: hyperamylasemia 4 h after the procedure > 80 U/L, 41/84 vs 23/59 (P = 0.32); hyperamylasemia 4 h after the procedure > 240 U/L, 19/84 vs 11/59 (P = 0.71); pancreatic pain, 13/84 vs 7/59 (P = 0.71); endoscopic bleeding, 10/84 vs 8/59 (P = 0.97); and the need for bleeding control, 10/84 vs 7/59 (P = 0.79). In the next part of the study, we analyzed the influence of the method chosen on the risk of hyperamylasemia with respect to an indication for endoscopic retrograde cholangiopancreatography, papillary anatomy and concomitant procedures performed. We determined that the hyperamylasemia risk was increased by more than threefold [odds ratio (OR) = 3.38; P = 0.027] after PCS in patients with a flat Vater’s papilla and more than fivefold (OR = 5.3; P = 0.049) after the PNK procedure in patients who required endoscopic homeostasis.
CONCLUSION: PCS and PNK do not differ in terms of efficacy or complication rates, but PNK is more often associated with the necessity for a two-step procedure.

Outcome of repeat ERCP after initial failed use of a needle knife for biliary access. Dig Dis Sci 2012; 57:1069-71. [PMID: 22147249 DOI: 10.1007/s10620-011-1982-6] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/12/2011] [Accepted: 11/09/2011] [Indexed: 12/28/2022]
Abstract
INTRODUCTION A needle knife is often used to gain bile duct access when standard techniques have failed. If unsuccessful, the next step may involve either radiological- or endoscopic ultrasound-guided biliary access. However, repeat endoscopic retrograde cholangiopancreatography (ERCP) may be an option if the patient's clinical condition permits. AIM To determine the success of repeat ERCP after failed use of a needle knife to gain biliary access. METHODS Retrospective analysis of all patients who underwent initial unsuccessful biliary cannulation after use of a needle knife between 2007 and 2010. RESULTS Seventy five patients were identified. Of these, 51 (68%) underwent repeat ERCP, and biliary cannulation was successful in 38 (75%). The median time to repeat ERCP was 7.7 days (range 1-28 days). Complications developed in two (4%) patients. These included one case each of wire-guided perforation and mild pancreatitis, both of which were resolved by conservative management. CONCLUSIONS Repeat ERCP within a few days after failed use of a needle knife for biliary access is associated with acceptable success and acceptable incidence of complications, and therefore obviates the need for alternative approaches for biliary access for most patients.

Precut fistulotomy for difficult biliary cannulation: is it a risky preference in relation to the experience of an endoscopist? Dig Dis Sci 2011; 56:1896-903. [PMID: 21082346 DOI: 10.1007/s10620-010-1483-z] [Citation(s) in RCA: 26] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/07/2010] [Accepted: 10/26/2010] [Indexed: 02/06/2023]
Abstract
BACKGROUND Several studies have reported on the correlation between the experience level of an endoscopist and the outcomes of precut procedures. However, there are limited data on the early use of the precut fistulotomy in relation to the experience of an endoscopist. AIM To evaluate the efficacy and safety of precut fistulotomy in difficult biliary cannulation after ERCP training. METHODS Two endoscopists, one at each tertiary referral center, performed the precut fistulotomy for difficult biliary cannulation between September 2008 and February 2010. The technical success, complications, and clinical outcomes in three groups were recorded prospectively over time. RESULTS A total of 159 (23.1%) patients underwent precut fistulotomy. The mean procedure time was decreased as the number of procedures increased (p < 0.01). The success rates of selective biliary cannulation in the three groups were 86.8, 86.8, and 88.7% respectively, for the first attempt (p = 0.77) and 93.7% for the second attempt. Post-ERCP pancreatitis developed in nine (5.7%) patients, which was not statistically significant between the three groups. As the frequency of papillary contacts increased, post-ERCP pancreatitis tended to increase (p = 0.017). In the multivariate analysis, more than 15 attempts at cannulating the major papilla prior to fistulotomy was a risk factor for pancreatitis (odds ratio 4.8, 95% CI 1.178-19.580, p = 0.029). CONCLUSIONS After therapeutic ERCP training involving at least 100 ERCPs, including at least half that were therapeutic cases and more than ten that were precut papillotomies, a precut fistulotomy can be performed safely and effectively in low-risk patients.

Abstract
Endoscopic retrograde cholangiopancreatography is an important tool in the diagnosis and treatment of pancreatobiliary diseases. A critical step in this procedure is deep cannulation of the bile duct as failure of cannulation generally results in an aborted procedure and failed intervention. Expert endoscopists usually achieve a high rate of successful cannulation while those less experienced typically have a much lower rate and a greater incidence of complications. Prolonged attempts at cannulation can result in significant morbidity to patients, anxiety for endoscopists, unnecessary radiation exposure and inefficient patient care. Here we review the most common endoscopic techniques used to achieve selective biliary cannulation. Pharmacologic aids to cannulation are also discussed briefly in this review.
