Abstract
Background and Aims Fluoroscopy-free endoscopic retrograde cholangiopancreatography for common bile duct stone (CBDS) clearance is usually offered only to pregnant patients. We initiated a multicenter, randomized controlled trial comparing clearance of non-complex CBDSs using fluoroscopy-free direct solitary cholangioscopy (DSC) to standard endoscopic retrograde cholangiography (ERC) to evaluate the wider applicability of the DSC-based approach. Here we report the initial results of stone clearance and safety in roll-in cases for the randomized controlled trial. Methods Twelve expert endoscopists at tertiary care centers in four countries prospectively enrolled 47 patients with non-complex CBDSs for DSC-assisted CBDS removal in an index procedure including fluoroscopy-free cannulation. Successful CBDS clearance was first determined by DSC and subsequently validated by final occlusion cholangiogram as the ERC gold standard. Results Fully fluoroscopy-free cannulation was successful in 42/47 (89.4%) patients. Brief fluoroscopy with minimal contrast injection was used in 4/47 (8.5%) patients during cannulation. Cannulation failed in 1/47 (2.1%) patients. Fluoroscopy-free complete stone clearance was reached in 38/46 (82.6%) cases. Residual stones were detected in the validation ERC occlusion cholangiogram in three cases. Overall serious adverse event rate was 2.1% (95% confidence interval 0.1-11.3): postprocedural pancreatitis in one patient. Conclusions In patients with non-complex CBDS, the fluoroscopy-free technique is easily transferred to endoscopic retrograde cholangiopancreatography experts with acceptable rates of cannulation and stone clearance and few serious adverse events.

Abstract
BACKGROUND & AIMS Chronic pancreatitis (CP) causes an abdominal pain syndrome associated with poor quality of life. We conducted a clinical trial to further investigate the efficacy and safety of camostat, an oral serine protease inhibitor that has been used to alleviate pain in CP. METHODS This was a double-blind randomized controlled trial that enrolled adults with CP with a baseline average daily worst pain score ≥4 on a numeric rating system. Participants were randomized (1:1:1:1) to receive camostat at 100, 200, or 300 mg 3 times daily or placebo. The primary end point was a 4-week change from baseline in the mean daily worst pain intensity score (0-10 on a numeric rating system) using a mixed model repeated measure analysis. Secondary end points included changes in alternate pain end points, quality of life, and safety. RESULTS A total of 264 participants with CP were randomized. Changes in pain from baseline were similar between the camostat groups and placebo, with differences of least squares means of -0.11 (95% CI, -0.90 to 0.68), -0.04 (95% CI, -0.85 to 0.78), and -0.11 (95% CI, -0.94 to 0.73) for the 100 mg, 200 mg, and 300 mg groups, respectively. Multiple subgroup analyses were similar for the primary end point, and no differences were observed in any of the secondary end points. Treatment-emergent adverse events attributed to the study drug were identified in 42 participants (16.0%). CONCLUSION We were not able to reject the null hypothesis of no difference in improvements in pain or quality of life outcomes in participants with painful CP who received camostat compared with placebo. Studies are needed to further define mechanisms of pain in CP to guide future clinical trials, including minimizing placebo responses and selecting targeted therapies.

Abstract
BACKGROUND Endoscopic papillectomy (EP) offers a safe and effective method for resection of ampullary adenomas. Data regarding the long-term resolution of adenoma following EP are limited. The aim of this study therefore was to examine the timing of recurrence after EP of ampullary adenomas. METHODS This was a single-center retrospective study including patients who received EP for ampullary adenomas from 8/2000 to 1/2018. Patients with confirmed complete eradication of adenoma were included in the recurrence analysis with recurrence defined as finding adenomatous histology after 1 negative surveillance endoscopy. Kaplan-Meier estimates were calculated to determine recurrence rates. RESULTS Of the 165 patients who underwent EP, 136 patients (mean age 61.9, 51.5% female) had adenomatous histology with a mean lesion size of 21.2 mm. A total of 124 (91.2%) achieved complete eradication with a follow-up of 345.8 person-years. Recurrence occurred in 20 (16.1%) patients at a mean of 3.2 (± 3) years (range 0.5-9.75 years) for a recurrence rate of 5.8 (95% CI 3.6-8.8) per 100 person-years. Nine (45%) recurrences occurred after the 1st 2 years of surveillance. Recurrence rate did not differ by baseline pathology [low-grade dysplasia: 5.2 (95% CI 3.0-9.0), high-grade dysplasia: 6.9 (95% CI 2.3-15.5), adenocarcinoma: 7.7 (95% CI 0.9-25.1)]. CONCLUSION Recurrence remains a significant concern after EP. Given the timing of recurrence, long surveillance periods may be necessary. Larger multicenter studies are needed, however, to determine appropriate surveillance intervals.

Abstract
OBJECTIVE To evaluate the safety and efficacy of endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) using a lumen-apposing metal stent (LAMS). BACKGROUND For patients with acute cholecystitis who are poor surgical candidates, EUS-GBD using a LAMS is an important treatment alternative to percutaneous gallbladder drainage. METHODS We conducted a regulatory-compliant, prospective multicenter trial at 7 tertiary referral centers in the United States of America and Belgium. Thirty consecutive patients with mild or moderate acute cholecystitis who were not candidates for cholecystectomy were enrolled between September 2019 and August 2021. Eligible patients had a LAMS placed transmurally with 30 to 60-day indwell if removal was clinically indicated, and 30-day follow-up post-LAMS removal. Endpoints included days until acute cholecystitis resolution, reintervention rate, acute cholecystitis recurrence rate, and procedure-related adverse events (AEs). RESULTS Technical success was 93.3% (28/30) for LAMS placement and 100% for LAMS removal in 19 patients for whom removal was attempted. Five (16.7%) patients required reintervention. Mean time to acute cholecystitis resolution was 1.6±1.5 days. Acute cholecystitis symptoms recurred in 10.0% (3/30) after LAMS removal. Five (16.7%) patients died from unrelated causes. Procedure-related AEs were reported to the FDA in 30.0% (9/30) of patients, including one fatal event 21 days after LAMS removal; however, no AEs were causally related to the LAMS. CONCLUSIONS For selected patients with acute cholecystitis who are at elevated surgical risk, EUS-GBD with LAMS is an alternative to percutaneous gallbladder drainage. It has high technical and clinical success, with low recurrence and an acceptable AE rate. Clinicaltrials.gov, Number: NCT03767881.

Abstract
OBJECTIVE We evaluated a protocolized endoscopic necrosectomy approach with a lumen-apposing metal stent (LAMS) in patients with large symptomatic walled-off pancreatic necrosis (WON) comprising significant necrotic content, with or without infection. SUMMARY BACKGROUND DATA Randomized trials have shown similar efficacy of endoscopic treatment compared with surgery for infected WON. DESIGN We conducted a regulatory, prospective, multicenter single-arm clinical trial examining the efficacy and safety of endoscopic ultrasound -guided LAMS with protocolized necrosectomy to treat symptomatic WON ≥6 cm in diameter with >30% solid necrosis. After LAMS placement, protocolized WON assessment was conducted and endoscopic necrosectomy was performed for insufficient WON size reduction and persistent symptoms. Patients with radiographic WON resolution to ≤ 3 cm and/or 60-day LAMS indwell had LAMS removal, then 6-month follow-up. Primary endpoints were probability of radiographic resolution by 60 days and procedure-related serious adverse events. RESULTS Forty consecutive patients were enrolled September 2018 to March 2020, of whom 27 (67.5%) were inpatients and 19 (47.5%) had clinical evidence of infection at their index procedure. Mean WON size was 15.0 ± 5.6 cm with mean 53.2% ± 16.7% solid necrosis. Radiographic WON resolution was seen in 97.5% (95% CI, 86.8%, 99.9%) by 60 days, without recurrence in 34 patients with 6-month follow-up data. Mean time to radiographic WON resolution was 34.1 ± 16.8 days. Serious adverse events occurred in 3 patients (7.5%), including sepsis, vancomycin-resistant enterococcal bacteremia and shock, and upper gastrointestinal bleeding. There were no procedure-related deaths. CONCLUSIONS Endoscopic ultrasound-guided drainage with protocolized endoscopic necrosectomy to treat large symptomatic or infected walled-off necrotic pancreatic collections was highly effective and safe.

Abstract
BACKGROUND AND AIMS Fully covered self-expandable metal stents (FCSEMSs) may offer a treatment option for pain associated with a dilated pancreatic duct (PD) in chronic pancreatitis (CP), but optimal patient selection and FCSEMS design, efficacy, and safety remain uncertain. We studied an investigational pancreatic FCSEMS for treatment of CP-associated pain. METHODS Patients with painful CP, a dominant distal PD stricture, and PD dilation upstream were enrolled in a prospective, multicenter, single-arm trial studying 6-month indwell of a 4- to 6-cm-long soft pancreatic FCSEMS. Primary efficacy and safety endpoints were pain reduction 6 months after FCSEMS indwell (performance goal ≥53%) and PD stenting-related serious adverse events (SAEs), respectively (performance goal <32%). The primary efficacy endpoint was assessed in patients with sufficiently severe and frequent pain at FCSEMS placement as a first stent or in exchange of a plastic stent. RESULTS Among 67 patients (mean age, 52.7 ± 12.5 years; mean time since CP diagnosis, 6.4 ± 6.4 years), 34 (50.7%) had plastic stent placement within 90 days of FCSEMS placement, and 46 patients were eligible for the primary efficacy endpoint analysis. Technical success was 97.0% (65/67). The observed primary efficacy (26.1%, 12/46) and safety endpoints (31.3%, 21/67) failed to meet the a priori study hypotheses. Study stent migration occurred in 47.7% of patients (31/65). CONCLUSIONS Six-month treatment with an FCSEMS did not lead to an expected degree of pain reduction, and migrations and SAEs were common. Further study is needed to clarify optimal decompressive strategy, FCSEMS design, and patient selection. (Clinical trial registration number: NCT02802020.).

Abstract
Background and study aims Dominant strictures (DS) occur in up to 60 % of patients with primary sclerosing cholangitis (PSC). Data regarding the long-term effects of stenting vs. dilation remain limited. The aim of this study was to compare the two treatment modalities in terms of transplantation-free survival. Patients and methods This single-center, retrospective study examined patients with PSC and DS treated endoscopically with a minimum of 1 year follow-up. Patients were divided into two cohorts: 1) those who received dilation alone; and 2) those who received both dilation and stenting. The primary outcome was transplantation-free survival, defined as time after index ERCP to liver transplantation. Results In all, 169 patients (54 in dilation cohort, 115 in stenting cohort) were included. The stenting cohort had a significantly higher Mayo PSC Risk Score (1.8 ± 1.1 vs. 0.9 ± 1.2) and presented with cholangitis more frequently (22.6 % vs. 1.9 %). During a follow-up period of 1198 person-years, 69 (40.8 %) patients received transplantation at a mean of 3.4 (± 2.9) years. There was no difference in transplantation rate in the stenting cohort [68 (95 % CI 5.2-8.8) per 100 person-years] compared to the dilation cohort [3.7 (95 % CI 2.1-6.0) per 100 person-years] and no difference in risk for transplantation (dilation cohort adjusted hazards ratio 0.67, 95 % CI 0.33-1.32). Conclusions Despite a higher Mayo Risk Score in the stenting group, there was no difference in transplantation-free survival between patients managed with stenting vs. dilation alone. Stenting, therefore, may offer benefit in patients with advanced PSC and DS.

Abstract
This article highlights the current status of cholangioscopy. In addition, the authors present their view on the future directions of cholangioscopy, including novel clinical applications, the need for technologic developments, and the expansion on the use of cholangioscopy in clinical practice. The authors envision that cholangioscopy will eventually become a conventional tool in the shelf of any biliary endoscopist. Future technologic improvements including optics, maneuverability, and full device accessories, plus the introduction of real-time artificial intelligence algorithms, will optimize the outcomes of cholangioscopy, but baseline proficiency in therapeutic endoscopic retrograde cholangiopancreatography will remain necessary for its successful utilization.

Abstract
BACKGROUND AND AIMS Patients with primary sclerosing cholangitis (PSC) and dominant biliary strictures carry increased risk for the development of cholangiocarcinoma. Although ERCP-based techniques including brush cytology and intraductal biopsy sampling represent first-line tissue sampling methods for dominant strictures, sensitivity is low. Probe-based confocal laser endomicroscopy (pCLE) offers microscopic-level imaging of subepithelial biliary mucosa. Because data regarding the use of pCLE in PSC are limited, we aimed to investigate its diagnostic performance in dominant strictures. METHODS This was a multicenter prospective study involving PSC patients with dominant strictures. ERCP with pCLE was performed with use of the Miami classification (2+ criteria for malignant diagnosis) and Paris classification. Final malignant diagnoses required histopathologic confirmation, and benign diagnoses required a minimum of 1 year of follow-up without development of cancer. RESULTS Fifty-nine patients (mean age, 49 years; 59% men) with 63 strictures were included in the study. Stricture locations included the common bile duct (31.7%), bifurcation (22.2%), and common hepatic duct (19%). Seven patients (11.9%) were found to have cholangiocarcinoma. The sensitivity and specificity of pCLE was 85.7% (95% confidence interval [CI], 42.1-99.6) and 73.1% (95% CI, 58.9-84.4), respectively. Within specific stricture locations, the highest sensitivity was seen at the bifurcation (100%; 95% CI, 2.5-100) and the right hepatic duct (100%; 95% CI, 29.2-100). The lowest sensitivities were seen at the common bile duct (25%; 95% CI, 5.5-57.2) and the left hepatic duct (28.6%; 95% CI, 3.7-70.9). CONCLUSIONS In this prospective multicenter study, pCLE had a high sensitivity in detecting cholangiocarcinoma, but technical aspects of the probe may limit evaluation in the common bile duct and left hepatic duct. Further evaluation is needed to elucidate the role of pCLE in the algorithm of excluding neoplasia in biliary strictures associated with PSC. (Clinical trial registration number: NCT02736708.).

Abstract
BACKGROUND Pancreatic endotherapy provides treatment options for the management of chronic pancreatitis-related structural complications such as pancreatic duct stones, strictures, and pancreatic fluid collections. Most studies detailing endotherapy, however, have focused on technical success outcomes such as stone clearance or stricture resolution.
AIM To review the effect of pancreatic endotherapy on patient-centered outcomes.
METHODS Systematic review of studies examining pancreatic endotherapy.
RESULTS A total of 13 studies including 3 randomized clinical trials were included. The majority of studies found an improvement in quality of life with pancreatic endotherapy.
CONCLUSION While pancreatic endotherapy does appear to improve quality of life, there are clear gaps in knowledge regarding many pancreatic endotherapy modalities. Furthermore, qualitative analysis is lacking in these studies and further work is needed to elucidate the patient experience with pancreatic endotherapy.

Abstract
BACKGROUND Biliary stricture evaluation with brush cytology and intraductal forceps biopsy carries a low sensitivity, but the combination of newer modalities may improve sensitivity. AIM To determine whether the addition of advanced modalities increases diagnostic yield of ERCP-based sampling. METHODS This single-center retrospective study evaluates patients with biliary strictures sampled using brush cytology. Operating characteristics were calculated for individual and combinations of modalities including cholangioscopy, fluoroscopy- and cholangioscopy-directed intraductal biopsy, fluorescence in situ hybridization (FISH), and confocal laser endomicroscopy. Analyses under Standard Criteria (SC) included malignant results as "positive" and Expanded Criteria (EC) included "suspicious" and "high-grade dysplasia" results as "positive." RESULTS A total of 614 patients were included, and 354 (57.8%) received brush cytology alone, which had a sensitivity of 38.5% (SC) to 40.3% (EC) and a specificity of 97.8% (EC) to 99.3% (SC). Combining brush cytology with fluoroscopy-guided biopsy (n = 259, 42.2%) had a sensitivity of 62.5% (SC) to 67.9% (EC) and specificity of 90.2% (EC) to 96.7% (SC). Adding FISH to brush cytology had a sensitivity of 84.2% (SC) to 87.5% (EC) and specificity of 54.1% (SC and EC), while cholangioscopy visualization addition resulted in a sensitivity of 80.4% (SC) to 92.2% (EC) and specificity of 67.3% (EC) to 89.1% (SC). There were no significant differences in sensitivity and specificity using SC and EC. CONCLUSIONS Brush cytology has a low sensitivity, but the addition of other modalities increases sensitivity. There was no difference in specificity between the SC and the EC, supporting the inclusion of "suspicious" impressions with malignant results at our center.

Abstract
OBJECTIVES Data regarding the safety of endoscopic retrograde pancreatography (ERP) are limited compared with biliary endoscopic retrograde cholangiopancreatography. The aim of this study was to determine adverse events (AEs) associated with therapeutic ERP. METHODS This single-center retrospective study examined consecutive therapeutic ERPs with the primary intention of cannulating the pancreatic duct. Multivariate logistic regression was performed to identify risk factors for AEs. RESULTS A total of 3023 ERPs were performed in 1288 patients (mean age, 50.3 years; 57.8% female) from January 2000 to January 2017. Overall AE rate was 18.9% with abdominal pain requiring admission (9.8%) and post-ERP pancreatitis (5.7%) being most common. On multivariate analysis, female sex (adjusted odds ratio [aOR], 2.3; 95% confidence interval [CI], 1.9-2.9), acute recurrent pancreatitis (aOR, 5.0; 95% CI, 1.7-15.3), chronic pancreatitis (aOR, 1.8; 95% CI, 1.3-2.6), and pancreatic sphincter of Oddi dysfunction (aOR, 2.1; 95% CI, 1.4-3.3) were associated with an increased risk of overall AEs. Pancreatic sphincterotomy (aOR, 1.9; 95% CI, 1.5-2.4) and therapeutic stenting (aOR, 1.6; 95% CI, 1.2-2.2) also increased the risk of AEs. CONCLUSIONS Nearly 1 in 5 patients who undergo therapeutic ERP will experience an AE; however, the rates of major AEs, including post-ERP pancreatitis, bleeding, and perforation, are low.

Abstract
Advanced endoscopy training programs (AETPs) were developed as a result of the lack of comprehensive endoscopic retrograde cholangiopancreatography (ERCP) training during gastroenterology fellowships. There is no standardized curriculum for AETPs and the influence of program- and trainer-associated factors on trainee competence in ERCP has not been investigated adequately. In prior work, we showed that advanced endoscopy trainees (AETs) achieve ERCP competence at varying rates.1,2 The aims of this study were to measure the variability in time given to AETs to attempt cannulation between AETPs and throughout the 1-year training period, and to determine the association between AET cannulation time and AET competence at the end of training.

Abstract
Background and study aims Cholangiopancreatoscopy-guided laser dissection or ablation (CPL) is a novel therapeutic modality for refractory benign strictures. Our aim was to describe the safety and efficacy of CPL for pancreaticobiliary disorders. Patients and methods Patients who underwent CPL using holmium or thulium laser between February 2017 and September 2019 were included. For stricture dissection, gentle strokes of the laser fiber from a distal to proximal approach were applied until luminal patency permitted advancement of the cholangiopancreatoscope. Immediate technical success was defined as ability to traverse the stricture with the cholangiopancreatoscope after CPL. Short-term technical success was defined as > 90 % resolution of the stricture on follow-up pancreatogram. Results Eleven patients underwent a mean of 3.6 ERCPs (mean total diameter of 14.2 Fr of stenting) prior to CPL. Indications included pancreatic duct stricture (n = 8), pancreaticojejunostomy anastomotic stricture (n = 1), bile duct stricture (n = 1) and pancreatic intraductal papillary mucinous neoplasm ablation (n = 1). Immediate technical success was 94.1 % and short-term technical success rates was 88.2 %. At a mean follow-up of 12.1 months, there have been no stricture recurrences. Conclusions CPL may be an effective therapy for strictures refractory to conventional dilation and multiple stenting.

Abstract
BACKGROUND & AIMS Fiducial markers are inert radiopaque gold or carbon markers implanted in or near pancreatic tumor to demarcate areas for image-guided radiation therapy. Endoscopic ultrasound (EUS) pre-loaded fiducial needles (PLNs) have been developed to circumvent technical issues associated with traditional back-loaded fiducials (BLNs). We performed a randomized controlled trial to compare procedure times in patients with pancreatic adenocarcinoma undergoing EUS-guided placement of BLNs vs PLNs. METHODS In a prospective study, 44 patients with pancreatic adenocarcinoma referred for fiducial marker placement at 2 tertiary care centers were assigned to groups that received PLNs (n = 22) or BLNs (n = 22); each group had the same proportion of patients with tumors of different locations (head or neck vs body or tail).The procedure was standardized among all endoscopists and placement of a minimum of 3 markers inside the tumor was defined as technical success. The times for procedure and fiducial placement were recorded, total number of fiducial markers used documented, and grade of procedure difficulty ranked by passing the needle or deploying the fiducials. Other recorded variables included tumor characteristics, fluoroscopy use, and the number of fiducials clearly seen by EUS and fluoroscopy. The primary aim was to compare the duration of EUS-guided fiducial insertion of BLNs vs PLNs. RESULTS The median placement time was significantly shorter in the PLN group (9 min) than the BLN group (16 min) (P < .001). However, the 44% reduction in time did not reach pre-specified levels (≥60%). Similar results were found after stratifying by tumor location. Deployment of BLNs was easier than deployment of PLNs (P = .03). There was no significant difference between groups in technical success, number of fiducials placed, EUS or fluoroscopic visualization, or adverse events. During simulation computed tomography and image-guided radiation therapy, there was no difference between groups in visualization of fiducials, migration rate, or accuracy of placement. CONCLUSIONS In a randomized controlled trial of 44 patients with pancreatic adenocarcinoma, we found EUS-guided placement of PLNs to require less time and produce similar results compared with BLNs. Further refinements in PLN delivery system are needed to increase the ease of deployment. Clinicaltrials.gov no: NCT02332863.

Abstract
Abstract
Background
Progressive right ventricular (RV) dysfunction is a natural progression of pulmonary arterial hypertension (PAH) which is associated with adverse clinical outcomes. The main contributor to progressive RV dysfunction is RV ischemia. Oxygen-sensitive (OS) cardiovascular magnetic resonance (CMR) has been used to determine the in-vivo myocardial oxygenation of the left ventricle (LV).
Purpose
The aim of the present study was to (1) Determine the feasibility of RV targeted rest/stress OS-CMR imaging in PAH patients and normal volunteers; (2) To define the presence and extent of RV myocardial ischaemia in patients with known PAH.
Methods
We prospectively recruited 20 patients with right heart catheter proven PAH and 9 normal (NC), age matched controls with no heart disease. The CMR examination involved standard functional imaging and OS-CMR imaging. OS-CMR images were acquired using a T2* sequence at rest and adenosine-induced stress vasodilatation. The RV was divided into 3 segments - RV anterior, RV free-wall and RV inferior. An OS-CMR signal intensity (SI) index (stress/rest signal intensity) was acquired at RV anterior, RV free-wall and RV inferior segments.
Results
All the PAH patients tolerated and completed the adenosine induced stress OS-CMR without any complications or adverse effects. In NC, reliable OS signal intensity changes was only obtained from the RV inferior segment. As RV dysfunction in PAH is a global process, hence this segment was used in both patients and NC for further comparison. RV OS-CMR signal intensity change between rest and stress in the normal volunteers was 17±4% (mean ± SD). 9 out of twenty (45%) of the PAH patients had a mean BOLD signal intensity change of less than 9% (or 2SD different from the mean values in normal volunteers). Overall, RV OS SI index between the PAH patients and controls was 11±9% vs 17±5% (p-value = 0.045) in RV inferior segment.
Conclusion
Pharmacological induced OS-CMR is a feasible and safe technique to identify and study myocardial oxygenation in the RV of PAH patients.

Abstract
BACKGROUND Biliary-enteric anastomotic strictures (AS) in long-limb surgical biliary bypass (LLBB) require percutaneous transhepatic biliary drains (PTBD), enteroscopy-assisted ERCP (E-ERCP), or surgical revision. AIM To compare E-ERCP and PTBD for AS treatment. METHODS E-ERCP stricturoplasty included dilation, cautery, and stent; PTBD included balloon dilation and serial drain upsizing events. RESULTS From May 2008 to October 2015, 71 patients (37 M, median age 52) had E-ERCP (n = 45) or PTBD (n = 26) for AS in Roux-en-Y hepaticojejunostomy: liver transplant (n = 28), cholecystectomy injury revision (n = 21), other (n = 13) or Whipple's resection (n = 9). Median follow-up is 11 months (range 1-56) in 67 (94%) patients. Technical success, clinical improvement, and adverse events between E-ERCP and PTBD were similar (76% vs. 77%, p = 0.89; 82% vs. 85%, p = 0.80, and 6% vs. 5%, p = 0.60, respectively). However, E-ERCP had fewer post-procedural hospitalization days (0.2 ± 0.65 vs. 4.5±10, p = 0.0001), mean procedures (4.4 ± 6.3 vs. 9.5 ± 8, p = 0.006), and median months of treatment to resolve AS (1, range 1-22 vs. 7, range 3-23; p = 0.003). Two patients in PTBD group required surgery. CONCLUSIONS (1) Technical success and clinical improvement are seen in the majority of LLBB patients with biliary-enteric AS undergoing E-ERCP or PTBD. (2) E-ERCP is associated with fewer procedures, post-procedure hospitalization days, and months to resolve AS. When expertise is available, E-ERCP to identify and treat AS should be considered as an alternative to PTBD.

Abstract
Background and study aims The role of the digital single-operator pancreatoscopy (D-SOP) with electrohydraulic (EHL) or laser lithotripsy (LL) in treating pancreatic ductal stones is unclear. We investigated the safety and efficacy of D-SOP with EHL or LL in patients with obstructing pancreatic duct stones.
Patients and methods Retrospective analysis of 109 patients who underwent D-SOP for pancreatic stones at 17 tertiary centers in the United States and Europe from February 2015 to September 2017. Logistic regression was performed to identify factors associated with the need for more than one D-SOP with EHL/LL.
Results Most patients were males (70.6 %),mean age 54.7 years. Fifty-nine (54.1 %) underwent EHL and 50 (45.9 %) underwent LL. Mean procedure time was longer in the EHL group (74.4 min vs 53.8 min; P < 0.001). Ducts were completely cleared (technical success) in 89.9 % of patients (94.1 % in EHL vs 100 % in LL; P = 0.243), achieved in a single session in 73.5 % of patients (77.1 % by EHL and 70 % by LL; P= 0.5).D-SOP failed in 11 patients (10.1 %); 6 patients were treated with extracorporeal shockwave lithotripsy (ESWL), 1 with surgery,1 with combined treatment (ESWL + D-SOP EHL) and 3 with other. Fourteen adverse events occurred in 11 patients (10.1 %). Patients with more than three ductal stones were more likely to have technical failure compared to those with less than three stones (17 % vs. 4.8 %; P = 0.04). Having more than three stones was independently associated with the need for more than one D-SOC EHL/LL session (OR 2.94, 95 % CI 1.13 – 7.65).
Conclusion D-SOP with EHL or LL is effective and safe in patients with pancreatic ductal stones.

Abstract
OBJECTIVES Evaluation of indeterminate biliary strictures remains challenging due to limited sensitivity of endoscopic tissue sampling. Biliary probe-based confocal laser endomicroscopy (pCLE) has shown promise to detect and exclude neoplasia. However, knowledge of whether individual inflammatory criteria are more prevalent in neoplasia compared to benign strictures is limited. The objective of this work is to improve diagnosis of neoplastic and inflammatory conditions using pCLE. MATERIALS AND METHODS The charts of all patients who underwent pCLE at a single referral center between 2009 and 2015 were reviewed. ERCP reports were reviewed for eleven Miami and Paris criteria. Primary outcome was the identification of neoplasia by histopathology (defined as high-grade dysplasia and/or adenocarcinoma). To model predictors of neoplasia, we fit a binary regression model incorporating data from pCLE operating criteria, pCLE impression, and PSC status. RESULTS 97 patients were identified. In the 27 patients with neoplasia, there was increasing number of Miami malignant criteria (Pearson r = 0.512, p < .001) while inflammatory criteria were less prevalent. 10% (5/51, p < .001) of patients with benign pCLE impression developed neoplasia, while 48% (22/46, p < .001) with suspicious pCLE impressions developed neoplasia. The binary regression model to predict neoplasia had a sensitivity of 83.3%, specificity of 92.5%, and overall accuracy 89.7%. CONCLUSIONS Presence of malignant criteria and absence of certain inflammatory criteria are more prevalent in patients with neoplasia. Our model, which weights individual imaging components, shows impressive sensitivity and specificity over prior prognostic efforts. Prospective studies will be required to evaluate this model.

Abstract
INTRODUCTION Increased faculty and resident responsibilities have led to the decreased time available for teaching clinical skills to medical students. Numerous advances in education and simulation have attempted to obviate this problem; however, documented success is lacking. Our objective was to describe a novel fresh cadaver-based, student-driven procedural skills lab and to compare the educational effectiveness of student instructors to the senior instructor (SI). METHODS This was a prospective study performed at an academic medical center. A pilot program, "Students Teaching Students," was introduced where four trained first-year medical students (TMS) instructed 41 other untrained first-year medical students in technical procedures. This study compared the teaching evaluations of the SI with the TMS teaching equivalent procedures. Paired t-test was used to determine statistically significant changes in procedural confidence between pre- and post-training. Utilizing a post-training questionnaire, average post-training confidence improvement values and objective post-training test scores of the participants were compared between TMS and SI, using a 2 sample t-test. Statistical significance was considered as a P-value<0.05. All statistical analyses were conducted in Stata 11 (StataCorp LP, College Station, TX, USA). RESULTS Twenty-nine out of 39 (74%) students completed the questionnaire. Both groups demonstrated a statistically significant improvement in subjective confidence level in performing each procedure when pre- and post-training scores were compared, while there was no statistically significant difference found in cognitive knowledge between the groups (p=0.73). There was no statistically significant difference in the mean confidence improvement between the SI and TMS groups for chest tube insertion (2.06 versus 1.92 respectively, p=0.587), femoral line placement (2.00 versus 1.94 respectively, p=.734) or student test score (88% versus 85% respectively). CONCLUSION Our results demonstrate that first-year medical students well-trained in technical skills, such as our TMS, may be a valuable additional teaching resource. The Students Teaching Students procedure lab employed in this study was effective at immediately increasing first-year medical students' confidence and technical skill. First-year medical students well-trained in technical skills, such as our TMS, may be a valuable additional teaching resource.

Abstract
BACKGROUND AND AIMS Per-oral pancreatoscopy (POP) permits direct evaluation of the pancreatic duct for the visualization and sampling of neoplastic lesions and treatment of pancreatic duct stones by using intraductal lithotripsy techniques. Pancreatic laser endotherapy of mucosa has been described in animal models for tumor ablation, but human experience is lacking. We describe 3 unique and challenging clinical situations that benefited from pancreatic laser dissection and ablation. CASE DESCRIPTION Case 1 was a 75-year-old woman with presumed divisum-associated chronic pancreatitis who had recurrent acute pancreatitis despite minor papilla sphincterotomy and therapeutic stent placement. POP showed a side-branch intraductal papillary mucinous neoplasm within the neck of the pancreas. POP-guided holmium laser ablation of neoplastic tissue was performed, followed by pancreatic stent placement every 6 months, with no further hospitalizations at 20 months of follow-up. Case 2 was a 69-year-old woman with divisum-associated chronic calcific pancreatitis and recalcitrant mid-body stenosis. Previous attempts at balloon dilation and stent placement failed to resolve the stenosis. POP-guided holmium laser dissection of the stenosis was pursued, with immediate radiographic resolution. Case 3 was a 65-year-old woman with chronic calcific pancreatitis and a large stone burden who underwent POP-guided electrohydraulic lithotripsy and partial stone extraction followed by stent placement. Unfortunately, the stent fractured during the subsequent removal attempt because the fragment was impacted in the pancreatic body. POP-guided laser dissection and lithotripsy were used to debulk dense fibrous tissue and stones surrounding the stent fragment, respectively, followed by removal. CONCLUSIONS Pancreatoscopy-guided laser endotherapy is a novel and potentially useful technique to manage difficult benign and neoplastic pancreatic disorders.

Abstract
BACKGROUND & AIMS It is unclear whether participation in competency-based fellowship programs for endoscopic ultrasound (EUS) and endoscopic retrograde cholangiopancreatography (ERCP) results in high-quality care in independent practice. We measured quality indicator (QI) adherence during the first year of independent practice among physicians who completed endoscopic training with a systematic assessment of competence. METHODS We performed a prospective multicenter cohort study of invited participants from 62 training programs. In phase 1, 24 advanced endoscopy trainees (AETs), from 20 programs, were assessed using a validated competence assessment tool. We used a comprehensive data collection and reporting system to create learning curves using cumulative sum analysis that were shared with AETs and trainers quarterly. In phase 2, participating AETs entered data into a database pertaining to every EUS and ERCP examination during their first year of independent practice, anchored by key QIs. RESULTS By the end of training, most AETs had achieved overall technical competence (EUS 91.7%, ERCP 73.9%) and cognitive competence (EUS 91.7%, ERCP 94.1%). In phase 2 of the study, 22 AETs (91.6%) participated and completed a median of 136 EUS examinations per AET and 116 ERCP examinations per AET. Most AETs met the performance thresholds for QIs in EUS (including 94.4% diagnostic rate of adequate samples and 83.8% diagnostic yield of malignancy in pancreatic masses) and ERCP (94.9% overall cannulation rate). CONCLUSIONS In this prospective multicenter study, we found that although competence cannot be confirmed for all AETs at the end of training, most meet QI thresholds for EUS and ERCP at the end of their first year of independent practice. This finding affirms the effectiveness of training programs. Clinicaltrials.gov ID NCT02509416.

Abstract
BACKGROUND & AIMS There have been few studies that compared the effects of lumen-apposing metal stents (LAMS) and double-pigtail plastic stents (DPS) in patients with peripancreatic fluid collections from pancreatitis. We aimed to compare technical and clinical success and adverse events in patients who received LAMS vs DPS for pancreatic pseudocysts and walled-off necrosis. METHODS We performed a retrospective study of endoscopic ultrasound-mediated drainage in 149 patients (65% male; mean age, 47 y) with pancreatic pseudocysts or walled-off necrosis (97 received LAMS and 152 received DPS), from January 2011 through September 2016 at a single center. We collected data on patient characteristics, outcomes, hospitalizations, and imaging findings. Technical success was defined as LAMS insertion or a minimum of 2 DPS. Clinical success was defined as resolution of pancreatic pseudocysts or walled-off necrosis based on imaging results. The primary outcome was resolution of peripancreatic fluid collection with reduced abdominal pain or obstructive signs or symptoms. Secondary outcomes included the identification and management of adverse events, number of additional procedures required to resolve fluid collection, and the recurrence of fluid collection. RESULTS Patients who received LAMS had larger peripancreatic fluid collections than patients who received DPS prior to intervention (P = .001), and underwent an average 1.7 interventions vs 1.9 interventions for patients who received DPS (P = .93). Technical success was achieved for 90 patients with LAMS (92.8%) vs 137 patients with DPS (90.1%) (odds ratio [OR] for success with DPS, 0.82; 95% CI, 0.33-2.0; P = .67). Despite larger fluid collections in the LAMS group, there was no significant difference in proportions of patients with clinical success following placement of LAMS (82 of 84 patients, 97.6%) vs DPS (118 of 122 patients, 96.7%) (OR for clinical success with DPS, 0.73; 95% CI, 0.13-4.0; P = .71). Adverse events developed in 24 patients who received LAMS (24.7%) vs 27 patients who received DPS (17.8%) (OR for an adverse event in a patient receiving a DPS, 0.82; 95% CI, 0.33-2.0; P = .67). However, patients with LAMS had a higher risk of pseudoaneurysm bleeding than patients with DPS (OR, 10.0; 95% CI, 1.19-84.6; P = .009). CONCLUSIONS In a retrospective study of patients undergoing drainage of pancreatic pseudocysts or walled-off necrosis, we found LAMS and DPS to have comparable rates of technical and clinical success and adverse events. Drainage of walled-off necrosis or pancreatic pseudocysts using DPS was associated with fewer bleeding events overall, including pseudoaneurysm bleeding, but bleeding risk with LAMS should be weighed against the trend of higher actionable perforation and infection rates with DPS.

Abstract
BACKGROUND AND STUDY AIMS Cholangiopancreatoscopy is utilized for diagnosis and therapy of pancreaticobiliary disorders. a fully-disposable, digital, single-operator cholangioscope (DSOC) was developed with high image resolution and wide field-of-view. This bench study compared the new DSOC to the previous semi-disposable, fiber-optic cholangioscope (FSOC) prior to the clinical availability of the DSOC system. METHODS Five experts performed one practice run followed by randomized runs comparing DSOC to FSOC in a biliary tract model consisting of three fixed left-intrahepatic tracts (LIHD), and variable common bile duct (CBD) and right-intrahepatic tracts (RIHD) with seven total lesions in multiple configurations. Timed runs aimed to visualize and target each lesion using miniature biopsy forceps. Definitions: visual success, visualizing targets; targeting success, touching target with forceps; complete run, touching seven targets within 20 minutes. Image quality, ease-of-use, and time to completion were recorded. RESULTS Thirty-seven evaluable runs (20 DSOC, 17 FSOC) were completed. DSOC was superior to FSOC in Visual (99 % vs. 67 %, P < 0.001) and targeting success (6.6 vs. 4.5, P = 0.009), proportion of complete runs (13 /20 vs. 0 /17, P < 0.001) and time of run (10.1 min vs. 15.4 min, P < 0.001). For fixed LIHD, DSOC achieved higher targeting success compared to FSOC (2.6 vs. 1.1, P < 0.001) with no difference in RIHD and CBD targets (4.0 vs. 3.4, P = 0.39). Investigators reported superior image quality and ease-of-use with DSOC. CONCLUSIONS In this model, DSOC performed superiorly to FSOC in image quality, visualization, and maneuverability. The model could potentially be utilized for training endoscopists less experienced with cholangiopancreatoscopy.

Abstract
BACKGROUND AND AIMS Through-the-needle microforceps are a recent addition to the EUS armamentarium for evaluation of pancreatic cystic lesions (PCLs). The main aim of this study was to assess the technical feasibility, diagnostic yield, and safety of EUS-guided microforceps biopsy for PCLs. METHODS Our electronic endoscopy database was queried to identify patients who underwent EUS-guided FNA (EUS-FNA) of PCLs and microforceps biopsies during the same procedure. A biopsy was done on the wall of the cyst with the microforceps through the 19-gauge needle, and cyst fluid was collected for cytology and carcinoembryonic antigen (CEA) levels. Adverse events were recorded per published American Society for Gastrointestinal Endoscopy criteria. RESULTS Twenty-seven patients underwent EUS-FNA and microforceps biopsy of PCLs from February 2016 to July 2017. Fourteen cysts were located in the pancreatic head and/or uncinate, and 13 were located in the body and/or tail region. Microforceps biopsies were technically successful in all cases and provided a pathology diagnosis in 24 of 27 cases (yield 88.9%). Microforceps biopsies diagnosed mucinous cyst in 9 patients (33.3%), serous cystadenoma in 4 (14.8%), neuroendocrine tumor in 1 (3.7%), and benign and/or inflammatory cyst in 10 (37.1%). In 7 patients (26%), microforceps biopsy results drastically changed the diagnosis, providing diagnoses otherwise not suggested by cytology or cyst fluid CEA levels. However, cytology provided a diagnosis of mucinous cyst in 4 cases (14.8%) not detected by microforceps biopsies. No adverse events were noted. CONCLUSION Microforceps biopsies were associated with high technical success, and an excellent safety profile and may be a useful adjunctive tool, complementing existing EUS-FNA sampling protocols for PCLs.

Abstract
OBJECTIVES Advanced ERCP techniques (AETs) for difficult biliary stones include peroral cholangioscopy (POC) with electrohydraulic/laser lithotripsy (EHL/LL), endoscopic papillary large balloon dilation (EPLBD) and mechanical lithotripsy (ML). We assess the efficacy of AETs. METHODS A retrospective query for AETs. PRIMARY OUTCOME Complete duct clearance. Secondary outcome: Complete duct clearance by technique. Statistical Analysis version 9.3 (SAS Inc., Cary, NC). RESULTS From 1/00 to 10/12, 349 patients were identified of which 222 (80% had prior ERCPs) had AETs. 211 with sufficient follow-up underwent 295 ERCPs; 280 of which were AET's. Index AETs: POC with EHL/LL (n = 46/211, 22%), ML (n = 84/211, 40%), EPLBD with mean balloon size of 11.5 ± 1.7 mm (n = 39/211, 18%) and combination AETs (n = 42/211, 20%). Stone characteristics: 76% had ≥1 stone, 81% extrahepatic and 32% had strictures. Number of stones (mean 2.5 and range 1-20) did not differ among groups. EPLBD had higher percentage (95%) of extrahepatic stones (p = .0003). The 'Combination' and 'POC' groups had larger stones (mean 17.7 mm ±6.4 and 16.8 mm ±6.1, respectively; p < .001). Complete clearance: 209/211 (99%) at index AET 167/211 (79%) or after mean of 2.5 ± 0.7 AETs in 42/211 (20%). Partial clearance: 2/211 (1%). Clearance at index AETs was higher with EPLBD (90%, p = .014). Adverse Events: 7/280 (2.5%). CONCLUSIONS AETs achieved clearance in 99%. EPLBD had higher clearance at index AET likely owing to higher extrahepatic stones. Larger stones, but not number, were associated with increased combination AETs and total ERCPs.

Abstract
BACKGROUND & AIMS On the basis of the Next Accreditation System, trainee assessment should occur on a continuous basis with individualized feedback. We aimed to validate endoscopic ultrasound (EUS) and endoscopic retrograde cholangiopancreatography (ERCP) learning curves among advanced endoscopy trainees (AETs) by using a large national sample of training programs and to develop a centralized database that allows assessment of performance in relation to peers. METHODS ASGE recognized training programs were invited to participate, and AETs were graded on ERCP and EUS exams by using a validated competency assessment tool that assesses technical and cognitive competence in a continuous fashion. Grading for each skill was done by using a 4-point scoring system, and a comprehensive data collection and reporting system was built to create learning curves by using cumulative sum analysis. Individual results and benchmarking to peers were shared with AETs and trainers quarterly. RESULTS Of the 62 programs invited, 20 programs and 22 AETs participated in this study. At the end of training, median number of EUS and ERCP performed/AET was 300 (range, 155-650) and 350 (125-500), respectively. Overall, 3786 exams were graded (EUS, 1137; ERCP-biliary, 2280; ERCP-pancreatic, 369). Learning curves for individual end points and overall technical/cognitive aspects in EUS and ERCP demonstrated substantial variability and were successfully shared with all programs. The majority of trainees achieved overall technical (EUS, 82%; ERCP, 60%) and cognitive (EUS, 76%; ERCP, 100%) competence at conclusion of training. CONCLUSIONS These results demonstrate the feasibility of establishing a centralized database to report individualized learning curves and confirm the substantial variability in time to achieve competence among AETs in EUS and ERCP.

Abstract
OBJECTIVE To test the hypothesis that urinary incontinence (UI) is associated with incident parkinsonism in older adults. METHODS We used data from 2,617 older persons without dementia. Assessment included baseline self-report UI and annual structured exam which assessed parkinsonian signs, motor performances, cognitive function, and self-report disabilities. We used a series of Cox proportional hazards models to examine the association of UI with parkinsonism and adverse health outcomes and a mixed-effect model to examine the association of UI with the annual rate of cognitive decline. In decedents, regression models were used to examine if UI proximate to death was related to postmortem indices of neuropathologies. RESULTS At baseline, more than 45% of participants reported some degree of UI. Over an average of nearly 8 years of follow-up, UI was associated with incident parkinsonism (hazard ratio [HR] = 1.07, 95% CI = 1.02, 1.12), death (HR = 1.07, 95% CI = 1.03, 1.11), incident ADL disability (HR = 1.11, 95% CI = 1.07, 1.16), and incident mobility disability (HR = 1.07, 95% CI = 1.02, 1.13). UI was not related to incident MCI (HR = 1.02, 95% CI = 0.97, 1.07), incident AD dementia (HR = 1.00, 95% CI = 0.95, 1.05) or to the rate of cognitive decline (Estimate = -.002, standard error = .002, p = .167). In 1,024 decedents with brain autopsy, UI proximate to death was related to PD pathology (Lewy body pathology and nigral neuronal loss), but not Alzheimer's disease pathology or other age-related neuropathologies. CONCLUSION UI in older adults is associated with incident parkinsonism and may identify older adults at risk for accumulating PD brain pathology.

Abstract
Background and study aim Our aim was to evaluate the first use in humans of a new, single-use, digital, single-operator intraductal cholangiopancreatoscopy system (IDCP). Patients and methods Data were collected retrospectively from four US institutions between February 2015 and April 2015. The visual impression of neoplasia or benign findings with IDCP was determined by the performing endoscopist. High grade dysplasia, intraductal papillary mucinous neoplasm, neuroendocrine tumor, and malignancy were categorized as neoplasia. Benign disease was defined as the absence of neoplasia during ≥ 6 months of follow-up. Results Patients (n = 108) with indeterminate strictures, dilatation, or difficult stones underwent IDCP. Of 74 patients with indeterminate stricture or dilatation, 29 (39 %) had neoplasia, of which 25 were confirmed by miniature biopsy forceps, 2 by surgical pathology, and 2 by the presence of metastatic disease on follow-up imaging. In patients with benign disease, 15 had concentric stenosis or normal/erythematous changes, 5 had low papillary mucosal projections, 6 had coarse granular mucosa, and 4 had nodular mucosa. Findings in patients with neoplastic disease included dilated, tortuous vessels ("tumor vessels"; n = 13), irregular margins with partial occlusion of the lumen (infiltrative stricture, n = 12), villous or nodular mass (n = 9), and finger-like villiform projections (n = 5). Operating characteristics for indeterminate stricture or dilatation were: 97 % sensitivity, 93 % specificity, 90 % positive predictive value, 98 % negative predictive value. Targeted biopsy yielded 86 % sensitivity and 100 % specificity. Stone clearance was noted in all cases. Adverse events occurred in 3 %. Conclusion The new IDCP system provides enhanced image resolution, and may improve the ability to target difficult stones and diagnose indeterminate strictures.

Abstract
Under the U.S. Lung Allocation Score (LAS) system, older and sicker patients are prioritized for lung transplantation (LT). The impact of these changes on health-related quality of life (HRQL) after transplant has not been determined. In a single-center prospective cohort study from 2010 to 2016, we assessed HRQL before and repeatedly after LT for up to 3 years using the SF12-Physical and Mental Health, the respiratory-specific Airway Questionnaire 20-Revised, and the Euroqol 5D/Visual Analog Scale utility measures by multivariate linear mixed models jointly modeled with death. We also tested changes in LT-Valued Life Activities disability, BMI, allograft function, and 6-min walk test exercise capacity as predictors of HRQL change. Among 211 initial participants (92% of those eligible), LT improved HRQL by all 5 measures (p < 0.05) and all but SF12-Mental Health improved by threefold or greater than the minimally clinically important difference. Compared to younger participants, those aged ≥65 improved less in SF12-Physical and Mental Health (p < 0.01). Improvements in disability accounted for much of the HRQL improvement. In the LAS era, LT affords meaningful and durable HRQL improvements, mediated by amelioration of disability. Identifying factors limiting HRQL improvement in selected subgroups, especially those aged ≥65, are needed to maximize the net benefits of LT.

Abstract
BACKGROUND AND AIMS Cholangiopancreatoscopy for evaluating pancreaticobiliary pathology is currently limited by suboptimal optics. The aim of this study was to characterize the operating characteristics of per-oral video cholangiopancreatoscopy with narrow-band imaging (POVCP) findings in indeterminate pancreaticobiliary disease and to describe their association with neoplasia. METHODS Data from consecutive patients undergoing POVCP for the evaluation of indeterminate pancreaticobiliary disease at a single tertiary care center were analyzed. Two experienced investigators had previously agreed on POVCP findings and terminology that were documented in endoscopy reports. Endoscopic procedural data from POVCPs performed between January 2006 and April 2015 and clinical data were abstracted from the endoscopic database and electronic medical records. Study endpoints included tissue-proven neoplasia or benign disease with ≥1 year of follow-up. RESULTS A total of 109 patients were identified; 13 were excluded because of the presence of stone disease, known pancreaticobiliary malignancy, or presumed benign disease with ≤1 year of follow-up. Most patients (85%) underwent POVCP for biliary disease and 15% underwent POVCP for a pancreatic cause. Tortuous and dilated vessels (P < .001), infiltrative stricture (P < .001), polypoid mass (P = .003), and the presence of fish-egg lesions (P = .04) were found to be significantly associated with neoplasia. The overall POVCP impression had a high sensitivity (85%) and negative predictive value (89%) in assessing for the presence of neoplasia. CONCLUSIONS Per-oral video cholangiopancreatoscopy is effective in the evaluation of indeterminate pancreaticobiliary disease. Tortuous and dilated vessels, infiltrative stricture, polypoid mass, and the presence of fish-egg lesions are significantly associated with neoplasia.

Abstract
BACKGROUND AND AIMS Pancreatic duct (PD) cannulation via the major papilla may be compromised by downstream obstruction of the ventral PD from a stone or stricture. In patients with a patent accessory PD, cannulation of the minor papilla permits stenting or stone removal upstream of the ventral PD obstruction. Data on this technique are limited. METHODS University of Colorado Hospital and Maine Medical Center endoscopy databases were queried for ERCPs with minor papilla cannulation. Technical success was defined as deep cannulation of the minor papilla. Minor papilla endotherapy included sphincterotomy, stricture dilation, stenting, or stone treatment. Clinical improvement was designated as >50% reduction in pain or narcotic analgesia. Follow-up was obtained by chart review and telephone contact. RESULTS Over a 22-year period, 464 patients had minor papilla cannulation. Congenital and incomplete pancreas divisum were excluded, and 64 patients met study criteria. Technical success was achieved in 58 of 64 patients (91%). In patients with stones, 25 of 34 (74%) had clearance using endoscopic techniques. Median follow-up was 15.5 months. Twelve of 28 patients (43%) on chronic narcotic regimens reported a reduction in narcotic use by >50%, and 32 of 44 patients (73%) reached for discussion noted improved abdominal pain by >50%. Thirteen patients required surgery for symptom control. CONCLUSIONS In this multicenter experience, 15% of patients undergoing minor papilla cannulation had acquired a ventral PD obstruction. Access via the minor papilla to the upstream main PD for endotherapy and clinical improvement was achieved in most patients. Increased and early recognition of these intensive therapeutic options may enhance treatment options for this complex group of patients.

Abstract
BACKGROUND AND AIMS EUS-guided FNA or biopsy sampling is widely practiced. Optimal sonographic visualization of the needle is critical for image-guided interventions. Of the several commercially available needles, bench-top testing and direct comparison of these needles have not been done to reveal their inherent echogenicity. The aims are to provide bench-top data that can be used to guide clinical applications and to promote future device research and development. METHODS Descriptive bench-top testing and comparison of 8 commonly used EUS-FNA needles (all size 22 gauge): SonoTip Pro Control (Medi-Globe); Expect Slimline (Boston Scientific); EchoTip, EchoTip Ultra, EchoTip ProCore High Definition (Cook Medical); ClearView (Conmed); EZ Shot 2 (Olympus); and BNX (Beacon Endoscopic), and 2 new prototype needles, SonoCoat (Medi-Globe), coated by echogenic polymers made by Encapson. Blinded evaluation of standardized and unedited videos by 43 EUS endoscopists and 17 radiologists specialized in GI US examination who were unfamiliar with EUS needle devices. RESULTS There was no significant difference in the ratings and rankings of these needles between endosonographers and radiologists. Overall, 1 prototype needle was rated as the best, ranking 10% to 40% higher than all other needles (P < .01). Among the commercially available needles, the EchoTip Ultra needle and the ClearView needle were top choices. The EZ Shot 2 needle was ranked statistically lower than other needles (30%-75% worse, P < .001). CONCLUSIONS All FNA needles have their inherent and different echogenicities, and these differences are similarly recognized by EUS endoscopists and radiologists. Needles with polymeric coating from the entire shaft to the needle tip may offer better echogenicity.

Abstract
BACKGROUND AND AIMS There are limited data on learning curves and competence in ERCP. By using a standardized data collection tool, we aimed to prospectively define learning curves and measure competence among advanced endoscopy trainees (AETs) by using cumulative sum (CUSUM) analysis. METHODS AETs were evaluated by attending endoscopists starting with the 26th hands-on ERCP examination and then every ERCP examination during the 12-month training period. A standardized ERCP competency assessment tool (using a 4-point scoring system) was used to grade the examination. CUSUM analysis was applied to produce learning curves for individual technical and cognitive components of ERCP performance (success defined as a score of 1, acceptable and unacceptable failures [p1] of 10% and 20%, respectively). Sensitivity analyses varying p1 and by using a less-stringent definition of success were performed. RESULTS Five AETs were included with a total of 1049 graded ERCPs (mean ± SD, 209.8 ± 91.6/AET). The majority of cases were performed for a biliary indication (80%). The overall and native papilla allowed cannulation times were 3.1 ± 3.6 and 5.7 ± 4, respectively. Overall learning curves demonstrated substantial variability for individual technical and cognitive endpoints. Although nearly all AETs achieved competence in overall cannulation, none achieved competence for cannulation in cases with a native papilla. Sensitivity analyses increased the proportion of AETs who achieved competence. CONCLUSION This study demonstrates that there is substantial variability in ERCP learning curves among AETs. A specific case volume does not ensure competence, especially for native papilla cannulation.
