Abstract
Pancreatitis is the most common complication following endoscopic retrograde cholangio-pancreatography (ERCP). With the progress of research in many drugs and technologies, promising efficacy has been achieved in preventing post-ERCP pancreatitis (PEP). Recently, combined prevention has received more attention in order to further reduce the incidence of PEP. However, there is no review about the combined prevention of PEP. This review summarizes the medication and ERCP techniques that are used to prevent PEP and emphasizes that appropriate combination prevention approaches should be based on risk stratification.

The Safety and Efficacy of an Unflanged 4F Pancreatic Stent in Transpancreatic Precut Sphincterotomy for Patients with Difficult Biliary Cannulation: A Prospective Cohort Study. J Clin Med 2022; 11:jcm11195692. [PMID: 36233560 PMCID: PMC9573508 DOI: 10.3390/jcm11195692] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2022] [Revised: 09/19/2022] [Accepted: 09/22/2022] [Indexed: 11/16/2022] Open
Abstract
Prophylactic pancreatic stenting effectively reduces the rate and severity of post-ERCP pancreatitis (PEP) in the precut technique; however, studies on the optimal type and duration of the stent are still lacking. This prospective study evaluated the incidence and severity of PEP and the rate of spontaneous stent dislodgement in patients undergoing transpancreatic precut sphincterotomy (TPS) accompanied by prophylactic pancreatic stenting with an unflanged plastic stent (4F × 5 cm) for difficult biliary cannulation. A total of 247 patients with naïve papilla were enrolled in this study, and data were collected prospectively. In the final analysis, 170 and 61 patients were included in the standard cannulation technique and TPS groups, respectively. The incidence of PEP in the standard cannulation technique and TPS groups was 3.5% and 1.6% (p = 0.679), respectively. The technical success rate of selective biliary cannulation in the TPS group was 91.8%. The spontaneous dislodgement rate of the prophylactic plastic stent was 98.4%. In conclusion, an unflanged pancreatic stent (4F × 5 cm) placement in TPS for patients with failed standard cannulation technique is a safe and effective measure due to low adverse events and few additional endoscopic procedures for removing the pancreatic duct (PD) stent.

"Salvage techniques" are the key to overcome difficult biliary cannulation in endoscopic retrograde cholangiopancreatography. Sci Rep 2022; 12:13627. [PMID: 35948566 PMCID: PMC9365799 DOI: 10.1038/s41598-022-17809-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2021] [Accepted: 08/01/2022] [Indexed: 11/30/2022] Open
Abstract
Although the efficacy and safety of salvage techniques for biliary cannulation in endoscopic retrograde cholangiopancreatography (ERCP) have been reported, few reports analyzed the choice of techniques and their clinical outcomes in large cohorts. This study aimed to evaluate the outcomes of biliary cannulation in patients with native papillae. We retrospectively identified 1021 patients who underwent initial ERCP from January 2013 to March 2020. We investigated background factors, treatment details, cannulation success rates, and adverse event rates. Then we analyzed a series of treatment processes, including salvage techniques such as double guidewire technique (DGT), needle knife pre-cutting (NKP), and transpancreatic pre-cut papillotomy (TPPP). The initial ERCP success rate using standard technique alone was 62.8%, which increased to 94.3% including salvage techniques. Salvage techniques were frequently required in patients with long oral protrusions (OR 2.38; 95% CI 1.80–3.15; p < 0.001). A total of 503 cases (49.3%) had long oral protrusions, 47.5% of which required the salvage techniques, much higher than 27.5% of not-long cases. Patients with long oral protrusions had a higher frequency of NKP. In conclusion, patients with long oral protrusions frequently required salvage techniques. Salvage techniques may help to overcome many difficult biliary cannulation cases.

Systematic review and meta-analysis of the incidence rates of adverse events after digestive endoscopy in children. Transl Pediatr 2022; 11:920-932. [PMID: 35800278 PMCID: PMC9253955 DOI: 10.21037/tp-22-179] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/07/2022] [Accepted: 06/14/2022] [Indexed: 11/12/2022] Open
Abstract
BACKGROUND With the widespread use of digestive endoscopy in children, a variety of adverse events (AEs) have occurred after digestive endoscopy. However, there are notable differences in the incidence of adverse reactions in digestive endoscopy in children at present, which makes it difficult to assess the safety of digestive endoscopy in children. METHODS Studies related to digestive endoscopy in children were screened from January 2005 to October 2021 from PubMed, Web of Science, Spring, CNKI, and Science Direct databases. RevMan5.3 and Stata were employed to carry out meta-analysis on the incidence of adverse respiratory events, myoclonus, abdominal pain, fever, bleeding, chest pain, sore throat, vomiting, and delayed capsule discharge after digestive endoscopy in children. The article quality was evaluated by the Agency for Healthcare Research and Quality (AHRQ). The chi-square test and I2 were adopted to test literature heterogeneity, and the article publication bias was assessed by displaying an inverted funnel plot as a funnel plot. RESULTS In all, 15 articles were included, involving a total of 27,770 children. In all, 15 articles were included, involving a total of 27,770 children. The risk ratio (RR) value of adverse respiratory events after digestive endoscopy in children was 1.31 [95% confidence interval (CI): 1.17 to 1.47, P<0.00001]; the odds ratio (OR) value of the incidence of myoclonus was 1.21 (95% CI: 1.01 to 1.46, P=0.04); the incidence of abdominal pain was 1.18 (95% CI: 1.11 to 1.27, P<0.00001); the incidence of fever was 1.09 (95% CI: 1.06 to 1.12, P<0.00001); the incidence of bleeding was 1.24 (95% CI: 0.94 to 1.64, P=0.13); the incidence of chest pain was 1.06 (95% CI: 1.03 to 1.09, P<0.0001); incidence of sore throat was 1.11 (95% CI: 1.05 to 1.18, P=0.0004); incidence of vomiting was 1.13 (95% CI: 1.06 to 1.21, P=0.0001); and the incidence of delayed capsule expulsion was 1.18 (95% CI: 1.00 to 1.40, P=0.05). DISCUSSION The incidence of AEs after digestive endoscopy in children was low, which can be used in the diagnosis and therapy of digestive system diseases in children.

Difficult biliary cannulation in patients with distal malignant biliary obstruction: An underestimated problem? Dig Liver Dis 2022; 54:529-536. [PMID: 34362708 DOI: 10.1016/j.dld.2021.07.010] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/20/2021] [Revised: 07/13/2021] [Accepted: 07/14/2021] [Indexed: 12/11/2022]
Abstract
BACKGROUND Failed biliary cannulation still poses a major challenge in patients undergoing Endoscopic Retrograde Cholangiopancreatography (ERCP). To date, there is a lack of data on rates of Difficult Biliary Cannulation (DBC) in patients with distal malignant biliary obstruction (DMBO). MATERIALS This was a retrospective study (09/2015 to 02/2019) of consecutive patients with DMBO that underwent ERCP in four Italian centers. The primary outcome was to evaluate the rate of DBC. Secondary outcomes were: cannulation failure, rate of adverse events (AEs), the predictive factors for DBC as well as for AEs. RESULTS A total of 622 patients with DMBO, were included in the study, with 351(56,4%) matching the definition of DBC. One-hundred and two ERCP-related AEs occurred in 97 of 622 patients (15,6%). Subjects with DBC showed a higher risk for AEs (p = 0.02). The lack of pancreatitis prophylaxis (p = 0.03), diagnosis of cholangiocarcinoma (p = 0.02), the use of papillotomy (OR=1.98; 95%CI = 1.14-3.45) and the combination of two or more techniques for cannulation (OR = 2.88; 95%CI = 1.04-7.97) were associated with the occurrence of AEs. CONCLUSIONS According to the results of this study, patients with DMBO carries a higher rate of DBC thus requiring alternative techniques for biliary drainage. Furthermore, DBC carries a high risk for AEs. Further prospective multicentric studies are needed to confirm these data in this specific subgroup of patients.

Abstract
BACKGROUND AND AIMS Several methods with variable efficacy have been proposed for difficult biliary cannulation in ERCP. We assessed the comparative efficacy of different strategies for difficult biliary cannulation through a network meta-analysis combining direct and indirect treatment comparisons. METHODS We identified 17 randomized controlled trials (2015 patients) that compared the efficacy of different adjunctive methods for difficult biliary cannulation (needle-knife techniques, pancreatic guidewire-assisted technique, pancreatic-assisted technique, and transpancreatic sphincterotomy) either with each other or with persistence with the standard cannulation techniques. The success rate of biliary cannulation and the incidence of post-ERCP pancreatitis (PEP) were the outcomes of interest. We performed pairwise and network meta-analysis for all treatments and used Grading of Recommendations Assessment, Development and Evaluation criteria to appraise quality of evidence. RESULTS Low-quality evidence supported the use of transpancreatic sphincterotomy over persistence with standard cannulation techniques (risk ratio [RR], 1.29; 95% confidence interval [CI], 1.05-1.59) and over any other adjunctive intervention (RR, 1.21 [95% CI, 1.01-1.44] vs pancreatic guidewire-assisted technique, RR, 1.19 [95% CI, 1.01-1.43] vs early needle-knife techniques, RR, 1.47 [95% CI, 1.03-2.10] vs pancreatic stent-assisted technique) for increasing the success rate of biliary cannulation. No other significant results were observed in any other comparisons. Based on the network model, transpancreatic sphincterotomy (P-score, .97) followed by early needle-knife techniques (P-score, .62) were ranked highest in terms of increasing the success rate of biliary cannulation. Early needle-knife techniques outperformed persistence with standard cannulation techniques in terms of decreasing PEP rate (RR, .61; 95% CI, .37-1.00), whereas both early needle-knife techniques and transpancreatic sphincterotomy led to lower PEP rates as compared with pancreatic guidewire-assisted technique (RR, .49 [95% CI, .23-.99] and .53 [95% CI, .30-.92], respectively). CONCLUSIONS Transpancreatic sphincterotomy increases the success rate of biliary cannulation as compared with persistence with the standard cannulation techniques. Early needle-knife techniques and transpancreatic sphincterotomy are superior to other interventions in decreasing PEP rates and should be considered in patients with difficult cannulation.

Abstract
Transpancreatic sphincterotomy (TPS) can be an alternative approach of difficult biliary access in endoscopic retrograde cholangiopancreatography (ERCP). We aimed to evaluate the efficacy and safety of TPS compared to needle-knife precut (NKP), considering the early and late outcomes of both techniques. The prospectively collected clinical data, ERCP procedure findings, and outcomes of patients who underwent ERCP with difficult biliary access in our hospital from July 2016 to January 2018 were retrospectively analyzed. The patients were divided into two groups according to the applied secondary cannulation techniques. The propensity score matching (PSM) was applied to reduce the potential selection bias and unify the preventive measures of post-ERCP pancreatitis (PEP) in both groups. A total of 125 patients were enrolled in this study, with 54.4% male and a mean age of 63.29 ± 16.33 years. NKP group included 82 patients, and 43 patients received TPS. Prophylactic pancreatic stents were placed in all patients with TPS and 58.5% of patients with NKP. After applying PSM, the cohort was comprised to 86 patients with 43 patients in each TPS and NKP groups. Successful selective cannulation was achieved by 95.3% using TPS and by 93% using NKP. The mean procedure time was shorter in the TPS group without significant difference. Compared to NKP, using TPS did not affect the rate of PEP. Moreover, TPS was associated with less frequent post-ERCP bleeding and perforation, but without significant differences (all p > 0.05). Patients who received TPS or NKP had no symptoms related to papillary stenosis or chronic pancreatitis during the follow-up period. In conclusion, using TPS in difficult cannulation cases was useful to achieve success cannulation with an acceptable PEP rate and less frequent post-ERCP bleeding and perforation compared to NKP. There were no symptoms related to papillary stenosis or chronic pancreatitis during the follow-up period.

Abstract
BACKGROUND In the setting of a naïve papilla, biliary cannulation is a key step in successfully performing endoscopic retrograde cholangiography. Difficult biliary cannulation (DBC) is associated with an increased risk of post-ERCP pancreatitis and failure of the whole procedure. SUMMARY Recommendations for biliary cannulation can be divided into (a) measures to reduce the likelihood of a difficult papilla situation a priori and (b) rescue techniques in case the endoscopist is actually facing DBC. (a) Careful inspection of the papillary anatomy and optimizing its accessibility by scope positioning is fundamental. A sphincterotome in combination with a soft-tip hydrophilic guidewire rather than a standard catheter with a standard guidewire should be used in most situations. (b) The most important rescue techniques are needle-knife precut, double-guidewire technique, and transpancreatic sphincterotomy. In few cases, anterograde cannulation techniques are needed. To this regard, the EUS-guided biliary drainage followed by rendezvous is increasingly used as an alternative to percutaneous transhepatic biliary drainage. Key Messages: Biliary cannulation can be accomplished with alternative retrograde or less frequently by salvage anterograde techniques, once conventional direct cannulation attempts have failed. Considering recent favorable data for the early use of transpancreatic sphincterotomy, an adopted version of the 2016 European Society for Gastrointestinal Endoscopy (ESGE) algorithm on biliary cannulation is proposed.

Abstract
BACKGROUND Endoscopic retrograde cholangiopancreatography (ERCP) is an important therapeutic modality in acute biliary pancreatitis (ABP) cases with cholangitis or ongoing common bile duct obstruction. Theoretically, inflammation of the surrounding tissues would result in a more difficult procedure. No previous studies examined this hypothesis. OBJECTIVES ABP and acute cholangitis (AC) without ABP cases were compared to assess difficulty of ERCP. METHODS The rate of successful biliary access, advanced cannulation method, adverse events, cannulation and fluoroscopy time were compared in 240 ABP cases and 250 AC cases without ABP. Previous papillotomy, altered gastroduodenal anatomy, and cases with biliary stricture were excluded. RESULTS Significantly more pancreatic guidewire manipulation (adjusted odds ratio (aOR) 1.921 [1.241-2.974]) and prophylactic pancreatic stent use (aOR 4.687 [2.415-9.098]) were seen in the ABP than in AC group. Average cannulation time in the ABP patients (248 vs. 185 s; p = 0.043) were longer than in AC cases. No difference was found between biliary cannulation and adverse events rates. CONCLUSION ERCP in ABP cases seem to be more challenging than in AC. Difficult biliary access is more frequent in the ABP cases which warrants the involvement of an experienced endoscopist.

Abstract
Background Selective deep biliary cannulation is the first and the most important step before further biliary therapy. Transpancreatic sphincterotomy (TPS), and needle knife fistulotomy (NKF) were commonly used in patients with difficult cannulation, but few studies compare the outcome between TPS and NKF. Methods A total of 78 patients who met the criteria of difficult cannulation in the National Taiwan University hospital from October 2015 to October 2017 were retrospectively reviewed. Their baseline demographics, success rate of biliary cannulation, and the rate of adverse events were assessed. Results 31 patients and 47 patients underwent TPS and NKF for difficult biliary access, respectively. The characteristics of the 2 groups were similar, but patients in TPS group had more frequent pancreatic duct cannulation. Bile duct cannulation was successful in 23 patients (74.2%) in the TPS group and 39 (83.0%) in the NKF group (P = 0.34). There was no difference between the TPS and NKF in the rate of adverse events, including post-ERCP pancreatitis (PEP) (16.1% vs. 6.4%, p = 0.17), and hemorrhage (3.2% vs. 8.5%, p = 0.35). No perforation occurred. Conclusions Both TPS and NKF have good biliary access rate in patient with difficult cannulation. TPS has acceptable successful rate and similar complication rate, compared with NKF.

Abstract
GOALS Our study aims to define success and complication rates of precut sphincterotomy with the needle-knife and transpancreatic papillary septotomy (TPS) techniques as experienced at a single, high-volume endoscopy centre. BACKGROUND Complication rates rise with increasing number of failed attempts at biliary cannulation; therefore, early precut sphincterotomy (PS) has been recommended. Selecting the ideal method for PS can be challenging and there is a paucity of data to help guide this decision. STUDY We performed a retrospective analysis over 37 months of endoscopic retrograde cholangiopancreatography (ERCP) experience at a single institution. We identified all ERCPs performed and stratified based on the presence of PS; if PS occurred, a thorough chart review was performed to identify success and complication rates. Patients received guideline-driven management for post-ERCP pancreatitis including rectal indomethacin and pancreatic duct stenting when appropriate. RESULTS We identified 1808 ERCP procedures performed during this time. Successful biliary cannulation was achieved in 1748 cases, yielding a success rate of 96.7% (Grades I-IV ERCP difficulty/complexity). PS was required in 232 cases (12.8%); we identified 88 TPS cases and 114 needle-knife precut sphincterotomy (NKPS) cases. Complications following PS procedures occurred in 9.1% of TPS patients and 11.4% of NKPS patients. Success rates for TPS and NKPS were 97.7% and 81.6%, respectively-a statistically significant difference (p<0.001). CONCLUSION This data supports TPS as a safe and effective option for biliary access in difficult cannulation settings when performed by experienced advanced endoscopists.

Abstract
Endoscopic retrograde cholangiopancreatography (ERCP) is a well-known procedure with both diagnostic and therapeutic utilities in managing pancreaticobiliary conditions. With the advancements of endoscopic techniques, ERCP has become a relatively safe and effective procedure. However, as ERCP is increasingly being utilized for different advanced techniques, newer complications have been noticed. Post-ERCP complications are known, and mostly include pancreatitis, infection, hemorrhage, and perforation. The risks of these complications vary depending on several factors, such as patient selection, endoscopist's skills, and the difficulties involved during the procedure. This review discusses post-ERCP complications and management strategies with new and evolving concepts.

Abstract
PURPOSE OF REVIEW ERCP is undergoing its 50th anniversary with a steady conversion from a diagnostic procedure to a therapeutic procedure. This paper shows a reflection of my 42 years of experience in the accession of biliary and pancreatic ducts and how the techniques have evolved to achieve a high rate of primary duct cannulation. RECENT FINDINGS There has been an increase in the primary approach to cannulation involving different cannulation catheters and guidewires, and we will review some of those available, realizing that the selection may vary depending on operator preference and team approach. Different views and experiences with these techniques will be presented. ERCP has evolved from a diagnostic to primarily a therapeutic procedure. This has resulted in the development of a variety of devices and techniques to access the ducts of interest. I have presented several of the techniques and my team approach that has evolved over a number of years. A more prospective evaluation of devices and wires is needed to see if one is superior to the other.

Abstract
Despite improvements in endoscopic technologies and accessories, development of advanced endoscopy fellowship programs, and advances in ancillary imaging techniques, biliary cannulation in endoscopic retrograde cholangiopancreatography (ERCP) can still be unsuccessful in up to 20% of patients, even in referral centers. Once cannulation has been deemed to be difficult, the risk of post-ERCP pancreatitis and technical failure inherently increases. A number of factors, including endoscopist experience and patient anatomy, have been associated with difficult biliary cannulation, but predicting a case of difficult cannulation a priori is often not possible. Numerous techniques such as pancreatic guidewire and stenting, early pre-cut, and rendezvous may be employed when standard approaches fail. Data regarding the rate of success and adverse events of these techniques have been variable, though most studies suggest that pancreatic duct stenting generally reduces the rate of post-ERCP pancreatitis in instances of difficult biliary cannulation. Here we provide a review on difficult biliary cannulation and discuss how the choice of which techniques to employ and how to best employ them should be individualized and take into account the skill of the endoscopist, the disorder being treated, the anatomy of the patient, and the available biomedical literature.

Abstract
In cases of difficult biliary cannulation, transpancreatic sphincterotomy (TPS) can be an alternative approach of biliary access. However, its success and safety profile have not been studied in detail. A systematic review and meta-analysis were performed to study the overall cannulation success and adverse events of TPS. These outcomes were also compared to other advanced cannulation methods. A systematic literature search was conducted to find all relevant articles containing data on TPS. Successful biliary cannulation and complications rates [post-ERCP pancreatitis (PEP), bleeding, and perforation rates] were compared in the pooled analyses of prospective comparative studies. The overall outcomes were calculated involving all studies on TPS. TPS was superior compared to needle-knife precut papillotomy (NKPP) and the double-guidewire method (DGW) regarding cannulation success (odds ratio [OR] 2.32; 95% confidence interval [CI] 1.37-3.93; and OR 2.72; 95% CI 1.30-5.69, respectively). The rate of PEP did not differ between TPS and NKPP or DGW; however, TPS (only retrospective studies were available for comparison) proved to be worse than needle-knife fistulotomy in this regard (OR 4.62; 95% CI 1.36-15.72). Bleeding and perforation rates were similar among these advanced techniques. There were no data about long-term consequences of TPS. The biliary cannulation rate of TPS is higher than that of the other advanced cannulation techniques, while the safety profile is similar to those. However, no long-term follow-up studies are available on the later consequences of TPS; therefore, such studies are strongly needed for its full evaluation.

Abstract
Since the first report of endoscopic retrograde cholangio-pancreatography (ERCP) in 1986 for the diagnosis of biliary-pancreatic disease, ERCP has become an important means for the diagnosis and treatment of biliary-pancreatic disease. At present, although the success rate of endoscopic selective biliary cannulation is more than 90%, there are still 5%-10% of cases with failed cannulation, for which assistive technology is needed as a supplementary to achieve successful cannulation. Repeated attempts correlate with a higher success rate of cannulation, but also extend the operating time and increase the incidence of complications. In recent years, the concept of difficult biliary cannulation has been put forward and gradually accepted by endoscopic physicians. In the cases of difficult biliary cannulation, endoscopic physicians can adjust the cannulation strategy in time to improve the success rate and reduce the complication rate. This paper summarizes the literature published recently to make a systematic review of the advances in the management of difficult biliary cannulation.
