Abstract
OBJECTIVE To investigate profiles of circulating immune signatures in healthy controls and chronic pancreatitis patients (CP) with and without a preceding history of acute pancreatitis (AP). METHODS We performed a phase 1, cross-sectional analysis of prospectively collected serum samples from the PROspective Evaluation of Chronic Pancreatitis for EpidEmiologic and Translation StuDies (PROCEED) study. All samples were collected during a clinically quiescent phase. CP subjects were categorized into two subgroups based on preceding episode(s) of AP. Healthy controls were included for comparison. Blinded samples were analyzed using an 80-plex Luminex assay of cytokines, chemokines, and adhesion molecules. Group and pairwise comparisons of analytes were performed between the subgroups. RESULTS In total, 133 patients with CP (111 with AP and 22 without AP) and 50 healthy controls were included. Among the 80 analytes studied, CP patients with a history of AP had significantly higher serum levels of pro-inflammatory cytokines (interleukin (IL)-6, IL-8, IL-1 receptor antagonist, IL-15) and chemokines (Cutaneous T-Cell Attracting Chemokine (CTACK), Monokine induced Gamma Interferon (MIG), Macrophage-derived Chemokine (MDC), Monocyte Chemoattractant Protein-1 (MCP-1)) compared to CP without preceding AP and controls. In contrast, CP patients without AP had immune profiles characterized by low systemic inflammation and downregulation of anti-inflammatory mediators, including IL-10. CONCLUSION CP patients with a preceding history of AP have signs of systemic inflammatory activity even during a clinically quiescent phase. In contrast, CP patients without a history of AP have low systemic inflammatory activity. These findings suggest the presence of two immunologically diverse subtypes of CP.

Abstract
OBJECTIVE This pilot study seeks to identify serum immune signatures across clinical stages of patients with chronic pancreatitis (CP). METHODS We performed a cross-sectional analysis of prospectively collected serum samples from the PROspective Evaluation of Chronic Pancreatitis for EpidEmiologic and Translation StuDies-study. CP subjects were categorised into three clinical stages based on the presence/absence of metabolic complications: (1) CP with no diabetes and exocrine pancreatic dysfunction (EPD), (2) CP with either diabetes or EPD, and (3) CP with diabetes and EPD. Blinded samples were analysed using an 80-plex Luminex assay of cytokines/chemokines/adhesion molecules. Group and pairwise comparisons were performed to characterise immune signatures across CP subgroups. RESULTS A total of 135 CP subjects (evenly distributed between clinical stages) and 50 controls were studied. Interleukin-6 (IL-6), interleukin-8 (IL-8), and soluble intercellular adhesion molecule 1 (sICAM-1) were significantly elevated in CP subjects compared to controls. The levels of IL-6 and IL-8 increased with advancing disease stages, with the highest levels observed in CP with diabetes and EPD (clinical stage 3). Furthermore, hepatocyte growth factor and macrophage-derived chemokine were significantly increased in clinical stage 3 compared to controls. CONCLUSION Our study reveals a progressive elevation in pro-inflammatory cytokines and chemokines with advancing clinical stages of CP. These findings indicate potential targets for the development of disease-modifying interventions.

Abstract
BACKGROUND AND AIMS Coaxial double-pigtail plastic stent (DPPS) placement is often performed within lumen-apposing metal stents (LAMSs) for drainage of pancreatic fluid collections (PFCs) to prevent adverse events (AEs) such as stent occlusion and bleeding. This study compares the safety and outcomes of LAMSs alone versus LAMSs with coaxial DPPSs for PFC management. METHODS Patients undergoing drainage of a PFC with LAMSs were retrospectively identified and categorized as LAMS or LAMS/DPPS based on initial drainage strategy. The AE rate, AE type, and clinical success were extracted by chart review. RESULTS One hundred eighty-five individuals (83 LAMS, 102 LAMS/DPPS) were identified. No significant differences were found in rates of clinical success (75.9% LAMS vs 69.6% LAMS/DDPS, P = .34) or overall AEs (15.7% LAMS vs 15.7% LAMS/DPPS, P = .825). CONCLUSIONS In this comparative single-center study, placement of a coaxial DPPS for drainage of PFCs with LAMSs did not affect rates of AEs or clinical success.

Abstract
Background and study aims Adequacy of endoscope disinfection in resource-limited settings is unknown. Adenosine triphosphate (ATP) testing is useful for evaluation of endoscope reprocessing, and ATP <200 relative light units (RLUs) after manual endoscope cleaning has been associated with adequacy of endoscope disinfection. Methods Consecutive endoscopes undergoing reprocessing at five World Gastroenterology Organisation (WGO) training centers underwent ATP testing before and after an on-site educational intervention designed to optimize reprocessing practices. Results A total of 343 reprocessing cycles of 65 endoscopes were studied. Mean endoscope age was 5.3 years (range 1-13 years). Educational interventions, based on direct observation of endoscope reprocessing practices at each site, included refinements in pre-cleaning, manual cleaning, high-level disinfection, and endoscope drying and storage. The percentage of reprocessing cycles with post-manual cleaning ATP ≧200 decreased from 21.4% prior to educational intervention to 14.8% post-intervention ( P =0.11). In multivariable logistic modelling, gastroscopes were significantly less likely (odds ratio [OR] 0.04, 95% confidence interval [CI] 0.01-0.19; P <0.001) than colonoscopes to achieve post-manual cleaning ATP < 200. No other factor (educational intervention, study site, endoscope age) was significantly associated with improved outcomes. Endoscope ID was not significantly associated with ATP values, and sites that performed manual versus automated HLD did not have significantly different likelihood of post-manual cleaning ATP <200 (OR 1.18, 95% CI 0.56-2.50; P =0.67). Conclusions In resource-limited settings, approximately 20% of endoscope reprocessing cycles may result in inadequate disinfection. This was not significantly improved by a comprehensive educational intervention. Alternative approaches to endoscope reprocessing are needed.

Abstract
Debilitating abdominal pain is a common symptom affecting most patients with chronic pancreatitis (CP). There are multiple underlying mechanisms that contribute to CP-related pain, which makes successful treatment difficult. The identification of biomarkers for subtypes of pain could provide viable targets for nonopioid interventions and the development of mechanistic approaches to pain management in CP. Nineteen inflammation- and nociception-associated proteins were measured in serum collected from 358 subjects with definite CP enrolled in PROspective Evaluation of Chronic Pancreatitis for EpidEmiologic and Translational StuDies, a prospective observational study of pancreatitis in US adult subjects. First, serum levels of putative biomarkers were compared between CP subjects with and without pain. Only platelet-derived growth factor B (PDGF-B) stood out, with levels significantly higher in the CP pain group as compared to subjects with no pain. Subjects with pain were then stratified into 4 pain subtypes (Neuropathic, Nociceptive, Mixed, and Unclassified). A comparison of putative biomarker concentration among 5 groups (no pain and 4 pain subtypes) identified unique proteins that were correlated with pain subtypes. Serum transforming growth factor beta 1 (TGFβ1) level was significantly higher in the Nociceptive pain group compared to the No pain group, suggesting that TGFβ1 may be a biomarker for nociceptive pain. The Neuropathic pain only group was too small to detect statistical differences. However, glycoprotein 130 (GP130), a coreceptor for interleukin 6, was significantly higher in the Mixed pain group compared to the groups lacking a neuropathic pain component. These data suggest that GP130 may be a biomarker for neuropathic pain in CP. PERSPECTIVE: Serum TGFβ1 and GP130 may be biomarkers for nociceptive and neuropathic CP pain, respectively. Preclinical data suggest inhibiting TGFβ1 or GP130 reduces CP pain in rodent models, indicating that additional translational and clinical studies may be warranted to develop a precision medicine approach to the management of pain in CP.

Abstract
BACKGROUND AND AIMS Patients with infected or symptomatic walled-off necrosis (WON) have high morbidity and health care utilization. Despite the recent adoption of nonsurgical treatment approaches, WON management remains nonalgorithmic. We investigated the impact of a protocolized early necrosectomy approach compared with a nonprotocolized, clinician-driven approach on important clinical outcomes. METHODS Records were reviewed for consecutive patients with WON who underwent a protocolized endoscopic drainage with a lumen-apposing metal stent (cases), and for patients with WON treated with a lumen-apposing metal stent at the same tertiary referral center who were not managed according to the protocol (control subjects). The protocol required repeat cross-sectional imaging within 14 days after lumen-apposing metal stent placement, with regularly scheduled endoscopic necrosectomy if WON diameter reduction was <50%. Control patients were treated according to their clinician's preference without an a priori strategy. Inverse probability of treatment weighting-adjusted analysis was used to evaluate the influence of being in the protocolized group on time to resolution. RESULTS A total of 24 cases and 47 control subjects were included. There were no significant differences in baseline characteristics. Although numbers of endoscopies and necrosectomies were similar, cases had lower adverse event rates, shorter intensive care unit stay, and required nutritional support for fewer days. On matched multivariate Cox regression, cases had earlier WON resolution (hazard ratio, 5.73; 95% confidence interval, 2.62-12.5). This was confirmed in the inverse probability of treatment weighting-adjusted analysis (hazard ratio, 3.4; 95% confidence interval, 1.92-6.01). CONCLUSIONS A protocolized strategy resulted in faster WON resolution compared with a discretionary approach without the need for additional therapeutic interventions, and with a better safety profile and decreased health care utilization.

Abstract
BACKGROUND AND AIMS Pain is a cardinal symptom of chronic pancreatitis (CP). Using Patient-Reported Outcomes Measurement Information System (PROMIS) measures, we characterized physical and mental health and symptom profiles of a well-defined cohort of individuals with CP and compared them with control subjects. Among patients with CP, we also examined associations between pain (intensity, temporal nature) and PROMIS symptom profiles and the prevalence of clinically significant psychological comorbidities. METHODS We analyzed baseline data in 488 CP patients and 254 control subjects enrolled in PROCEED (Prospective Evaluation of Chronic Pancreatitis for Epidemiologic and Translational Studies), an ongoing longitudinal cohort study. Participants completed the PROMIS-Global Health, which captures global physical and mental health, and the PROMIS-29 profile, which captures 7 symptom domains. Self-reported pain was categorized by severity (none, mild-moderate, severe) and temporal nature (none, intermittent, constant). Demographic and clinical data were obtained from the PROCEED database. RESULTS Pain was significantly associated with impairments in physical and mental health. Compared with participants with no pain, CP participants with severe pain (but not mild-moderate pain) had more decrements in each PROMIS domain in multivariable models (effect sizes, 2.54-7.03) and had a higher prevalence of clinically significant depression, anxiety, sleep disturbance, and physical disability (odds ratios, 2.11-4.74). Similar results were noted for constant pain (but not intermittent pain) for PROMIS domains (effect sizes, 4.08-10.37) and clinically significant depression, anxiety, sleep disturbance and physical disability (odds ratios, 2.80-5.38). CONCLUSIONS Severe and constant pain are major drivers for poor psychological and physical health in CP. Systematic evaluation and management of psychiatric comorbidities and sleep disturbance should be incorporated into routine management of patients with CP. (ClinicalTrials.gov, Number: NCT03099850).

Abstract
BACKGROUND AND AIMS The optimal therapeutic approach for walled-off necrosis (WON) is not fully understood, given the lack of a validated classification system. We propose a novel and robust classification system based on radiologic and clinical factors to standardize the nomenclature, provide a framework to guide comparative effectiveness trials, and inform the optimal WON interventional approach. METHODS This was a retrospective analysis of patients who underwent endoscopic management of WON by lumen-apposing metal stent placement at a tertiary referral center. Patients were classified according to the proposed QNI classification system: quadrant ("Q"), represented an abdominal quadrant distribution; necrosis ("N"), denoted by the percentage of necrosis of WON; and infection ("I"), denoted as positive blood culture and/or systemic inflammatory response syndrome reaction with a positive WON culture. Two blinded reviewers classified all patients according to the QNI system. Patients were then divided into 2 groups: those with a lower QNI stratification (≤2 quadrants and ≤30% necrosis; group 1) and those with a higher stratification (≥3 quadrants, 2 quadrants with ≥30% necrosis, or 1 quadrant with >60% necrosis and infection; group 2). The primary outcome was mean time to WON resolution. Secondary procedural and clinical outcomes between the groups were compared. RESULTS Seventy-one patients (75% men) were included and stratified by the QNI classification; group 1 comprised 17 patients and group 2, 54 patients. Patients in group 2 had a higher number of necrosectomies, longer hospital stays, and more readmissions. The mean time to resolution was longer in group 2 than in group 1 (79.6 ± 7.76 days vs 48.4 ± 9.22 days, P = .02). The mortality rate was higher in group 2 (15% vs 0%, P = .18). CONCLUSIONS Despite the heterogeneous nature of WON in severe acute pancreatitis, a proposed QNI system may provide a standardized framework for WON classification to inform clinical trials, risk-stratify the disease course, and potentially inform an optimal management approach.

Abstract
BACKGROUND & AIMS Chronic pancreatitis (CP) is associated with osteopathy (osteoporosis or osteopenia). However, existing literature is mostly limited to retrospective or administrative studies that have not clearly defined the prevalence and risk factors. Our aim was to identify patient- and disease-related associations with osteopathy in a prospective cohort study of CP. METHODS We studied 282 subjects with definitive CP enrolled in the PROCEED study who had a baseline dual-energy X-ray absorptiometry (DXA) scan. Osteopenia and osteoporosis were defined using the lowest T-scores. Clinical data were collected using standardized case report forms. Comparisons were performed with a multivariate logistic regression model with forward selection to identify risk factors for osteopathy. RESULTS The majority of subjects had osteopathy on DXA scan (56.0%; 17.0% osteoporosis; 39.0% osteopenia). Subjects with osteopathy had a higher prevalence of traumatic (40.0% vs 26.4%; P = .02) and spontaneous fractures (3.9% vs 0; P = .04). On multivariate analysis, older age (odds ratio [OR], 1.29 per 5 years; 95% confidence interval [CI], 1.15-1.45), female sex (OR, 3.08; 95% CI, 1.75-5.43), white race (OR, 2.68; 95% CI, 1.20-6.01), and underweight body mass index category (OR, 7.40; 95% CI, 1.56-34.99) were associated with higher probability of osteopathy. There were no significant associations between osteopathy and other patient and disease-related features of CP. CONCLUSION In the largest study of patients with CP who underwent DXA screening, the majority had osteopathy. There are overlapping risk factors with osteopathy in the general population, but the high prevalence in men and younger women supports the need for future investigations into the mechanisms of bone loss in CP.

Abstract
BACKGROUND Endoscopic ultrasound (EUS)-guided main pancreatic duct (PD) access may be used when conventional endoscopic retrograde cholangiopancreatography (ERCP) techniques fail. The use of a percutaneous transluminal angioplasty balloon (PTAB), originally developed for vascular interventions, can be used to facilitate transmural (e.g., transgastric) PD access and to dilate high-grade pancreatic strictures.
AIM To describe the technique, efficacy, and safety of PTABs for EUS-guided PD interventions.
METHODS Patients who underwent EUS with use of a PTAB from March 2011 to August 2021 were retrospectively identified from a tertiary care medical center supply database. PTABs included 3-4 French angioplasty catheters with 3-4 mm balloons designed to use over a 0.018-inch guidewire. The primary outcome was technical success. Secondary outcomes included incidence of adverse events (AEs) and need for early reintervention.
RESULTS A total of 23 patients were identified (48% female, mean age 55.8 years). Chronic pancreatitis was the underlying etiology in 13 (56.5%) patients, surgically altered anatomy (SAA) with stricture in 7 (30.4%), and SAA with post-operative leak in 3 (13.0%). Technical success was achieved in 20 (87%) cases. Overall AE rate was 26% (n = 6). All AEs were mild and included 1 pancreatic duct leak, 2 cases of post-procedure pancreatitis, and 3 admissions for post-procedural pain. No patients required early re-intervention.
CONCLUSION EUS-guided use of PTABs for PD access and/or stricture management is feasible with an acceptable safety profile and can be considered in patients when conventional ERCP cannulation fails.

Abstract
BACKGROUND AND AIMS Malignant biliary strictures can be difficult to diagnose, with up to 20% considered indeterminate after initial tissue sampling. This study aimed to determine the performance characteristics of transpapillary biopsy sampling (TPB) and fluorescence in situ hybridization (FISH) in isolation or in combination with standard brush cytology (BC) in patients who received trimodality sampling for biliary strictures. METHODS This single-center retrospective cohort study included patients with biliary strictures undergoing ERCP with trimodality sampling between September 2014 and April 2019. Performance characteristics for each diagnostic test alone and in combination were calculated. RESULTS Two hundred four patients underwent trimodality biliary sampling, including 104 (51.0%) with malignancy. The diagnostic sensitivity for malignancy with BC (17.3%) significantly improved with dual modality (BC+FISH, 58.7%; BC+TPB, 40.4%) or trimodality sampling (68.3%; P < .001 for all comparisons). Trimodality sampling improved diagnostic sensitivity for malignancy compared with BC+FISH (P = .002) and BC+TPB (P < .001). There was no statistically significant difference in the sensitivity of trimodality sampling in detecting cholangiocarcinoma (79.7%) compared with pancreatic cancer (62.5%; P = .1). Among 57 patients with primary sclerosing cholangitis (PSC), the sensitivity of detecting biliary malignancy (n = 20) was 20% for BC and significantly improved with the addition of FISH (80%; P < .001) but not with TPB (35.0%; P = .25). Trimodality sampling did not further improve diagnostic sensitivity (85%) over BC+FISH (80%) for malignancy in the setting of PSC (P = 1). CONCLUSIONS Trimodality sampling improves the diagnostic sensitivity for the detection of malignant biliary strictures with no significant difference in sensitivity for cholangiocarcinoma compared with pancreatic cancer. However, in patients with PSC, trimodality sampling was not superior to BC+FISH.

Abstract
Background and study aims Limited evidence suggests that endoscopy capacity in sub-Saharan Africa is insufficient to meet the levels of gastrointestinal disease. We aimed to quantify the human and material resources for endoscopy services in eastern African countries, and to identify barriers to expanding endoscopy capacity. Patients and methods In partnership with national professional societies, digestive healthcare professionals in participating countries were invited to complete an online survey between August 2018 and August 2020. Results Of 344 digestive healthcare professionals in Ethiopia, Kenya, Malawi, and Zambia, 87 (25.3 %) completed the survey, reporting data for 91 healthcare facilities and identifying 20 additional facilities. Most respondents (73.6 %) perform endoscopy and 59.8 % perform at least one therapeutic modality. Facilities have a median of two functioning gastroscopes and one functioning colonoscope each. Overall endoscopy capacity, adjusted for non-response and additional facilities, includes 0.12 endoscopists, 0.12 gastroscopes, and 0.09 colonoscopes per 100,000 population in the participating countries. Adjusted maximum upper gastrointestinal and lower gastrointestinal endoscopic capacity were 106 and 45 procedures per 100,000 persons per year, respectively. These values are 1 % to 10 % of those reported from resource-rich countries. Most respondents identified a lack of endoscopic equipment, lack of trained endoscopists and costs as barriers to provision of endoscopy services. Conclusions Endoscopy capacity is severely limited in eastern sub-Saharan Africa, despite a high burden of gastrointestinal disease. Expanding capacity requires investment in additional human and material resources, and technological innovations that improve the cost and sustainability of endoscopic services.

Abstract
BACKGROUND AND AIMS Select patients with acute cholecystitis (AC) are poor candidates for cholecystectomy. ERCP-guided transpapillary gallbladder (GB) drainage (ERGD) is one modality for nonoperative management of AC in these patients. Our primary aim was to evaluate long-term success of destination ERGD. Secondary aims were the rate of technical and clinical success, number of repeat procedures, rate of adverse events, and risk factors for recurrent AC. METHODS Consecutive patients with AC who were not candidates for cholecystectomy underwent ERGD with attempted transpapillary GB plastic double-pigtail stent placement at a tertiary hospital from January 2008 to December 2019. Long-term success was defined as no AC after ERGD until 6 months, death, or reintervention. Technical success was defined as placement of at least 1 transpapillary stent into the GB and clinical success as resolution of AC symptoms with discharge from the hospital. RESULTS Long-term success was achieved in 95.9% of patients (47/49), technical success in 96% (49/51), and clinical success 100% in those with technical success. Mild adverse events occurred in 5.9% (n = 3). Mean follow-up was 453 days after ERGD (range, 18-1879). A trend toward longer time to recurrence of AC was seen in patients with 2 rather than 1 GB stent placed (P = .13), and more repeat procedures were performed when a single stent was placed (P = .045). CONCLUSIONS ERGD with transpapillary GB double-pigtail stent placement is a safe and effective long-term therapy for poor surgical candidates with AC. Risk factors for recurrence include stent removal and single-stent therapy. Double-stent therapy is not always technically feasible but may salvage failed single-stent therapy or recurrence after elective stent removal and may therefore be the preferred treatment modality.

Abstract
BACKGROUND Exposure to polycyclic aromatic hydrocarbons (PAHs) is a risk factor for esophageal squamous cell carcinoma (ESCC) in high-incidence areas of China, Iran and Brazil, but PAH assessments have not been conducted in East Africa, another ESCC hot spot. OBJECTIVE To evaluate demographic or lifestyle factors associated with the PAH biomarker concentrations in the study population, and whether PAH metabolite concentrations showed any associations with esophageal precancerous lesions. METHODS We recruited a community-based sample of 289 asymptomatic adults from a rural area of Kenya and performed Lugol's chromoendoscopy to detect esophageal squamous dysplasia (ESD); participants completed a questionnaire and provided a spot urine specimen. We analyzed urine for seven hydroxylated metabolites of naphthalene, fluorene, phenanthrene, and pyrene at the U.S. National Center for Environmental Health, and compared creatinine-corrected PAH metabolite concentrations with questionnaire data and the presence of ESD. RESULTS PAH metabolite concentrations among never tobacco users in these rural Kenya residents were 2.4-28.1 times higher than those reported from never tobacco users in Iran, Brazil and the USA. Female sex, cooking indoors, having no post-primary education, and age <50, but not tobacco use, were positively and significantly associated with PAH metabolite concentrations. Almost all participants used wood as cooking fuel. Nine participants had advanced ESD. Adjusted logistic regression showed a significant association between 2-hydroxynaphthalene (OR = 4.19, 95%CI: 1.01-17.47) and advanced ESD. All other PAH metabolites had positive but non-significant associations with advanced ESD. CONCLUSIONS Urinary PAH metabolite concentrations among never tobacco users are markedly higher in this group from Kenya than in other populations and are associated with indoor cooking with wood on open, unvented stoves. These metabolite concentrations were also associated with the presence of advanced esophageal dysplasia. Our findings underline the importance of assessing alternative cooking conditions to reduce PAH exposure in this population.

Abstract
INTRODUCTION Severe abdominal pain is a cardinal symptom of chronic pancreatitis (CP) associated with a high economic and societal burden. In other chronic pain conditions, cognitive-behavioral therapy (CBT) has demonstrated efficacy in improving patient outcomes (e.g., pain-related disability and depression). However, CBT has not yet been evaluated in adult patients with painful CP. We aimed to (i) evaluate the feasibility and acceptability of an adapted Internet CBT program for CP and (ii) generate pilot data regarding the effects of treatment on patient pain outcomes. METHODS Thirty adults (mean age = 49.8 years, SD = 12.5; 80% women) with suspected or definite CP were randomized to Internet CBT (Pancreatitis Pain Course) versus control. The Pancreatitis Pain Course has 5 CBT lessons (e.g., thought challenging, relaxation, and activity pacing) delivered over 8 weeks. Pain interference, pain intensity, and quality of life were assessed at pretreatment, posttreatment, and the 3-month follow-up. Qualitative interviews were conducted at posttreatment with a subset of participants. RESULTS Eighty percent of participants rated the program as highly acceptable; 64.3% completed all 5 lessons. Qualitative data revealed positive perceptions of program features, relevancy, and skills. Patients randomized to Internet CBT demonstrated moderate to large effects in reducing pain intensity and pain interference from baseline to 3 months. The proportion of treatment responders (>30% improvement) was significantly greater in the Internet-CBT group than in the control group (50% vs 13%, Fisher exact t test P = 0.04). DISCUSSION In this first trial of CBT pain self-management in CP, feasibility, acceptability, and preliminary efficacy for reducing pain and disability were demonstrated. Future definitive trials of CBT are needed.

Abstract
BACKGROUND Endoscopic intervention for pancreatic fluid collections (PFCs) with disconnected pancreatic duct syndrome (DPDS) has been associated with failures and increased need for additional endoscopic and non-endoscopic interventions. The primary aim of this study was to determine the outcomes of endoscopic ultrasound (EUS)-guided transmural drainage of PFCs in patients with DPDS. METHODS In patients undergoing EUS-guided drainage of PFCs from January 2013 to January 2018, demographic profiles, procedural indications and details, adverse events, outcomes, and subsequent interventions were retrospectively collected. Overall treatment success was determined by PFC resolution on follow-up imaging or stent removal without recurrence. RESULTS EUS-guided drainage of PFCs was performed in 141 patients. DPDS was present in 57 of them (40 %) and walled-off necrosis was the most frequent type of PFC (55 %). DPDS was not associated with lower clinical success, increased number of repeat interventions, or increased time to PFC resolution. Patients with DPDS were more likely to be treated with permanent transmural plastic double-pigtail stents (odds ratio [OR] 6.4; 95 % confidence interval [CI] 2.5 - 16.5; P < 0.001). However, when stents were removed, DPDS was associated with increased PFC recurrence after stent removal (OR 8.0; 95 %CI 1.2 - 381.8; P = 0.04). CONCLUSIONS DPDS frequently occurs in patients with PFCs but does not negatively impact successful resolution. DPDS is associated with increased PFC recurrence after stent removal.

Abstract
Background Abdominal pain is a debilitating symptom affecting ∼80% of pancreatic cancer (PC) patients. Pancreatic duct (PD) decompression has been reported to alleviate this pain, although this practice has not been widely adopted. We aimed to evaluate the role, efficacy, and safety of endoscopic PD decompression for palliation of PC post-prandial obstructive-type pain. Methods A systematic review until 7 October 2020 was performed. Two independent reviewers selected studies, extracted data, and assessed the methodological quality. Results We identified 12 publications with a total of 192 patients with PC presenting with abdominal pain, in whom PD decompression was attempted, and was successful in 167 patients (mean age 62.5 years, 58.7% males). The use of plastic stents was reported in 159 patients (95.2%). All included studies reported partial or complete improvement in pain levels after PD stenting, with an improvement rate of 93% (95% confidence interval, 79%–100%). The mean duration of pain improvement was 94 ± 16 days. Endoscopic retrograde cholangiopancreatography (ERCP)-related adverse events (AEs) were post-sphincterotomy bleeding (1.8%), post-ERCP pancreatitis (0.6%), and hemosuccus pancreaticus (0.6%). AEs were not reported in two patients who underwent endoscopic ultrasound-guided PD decompression. In the 167 patients with technical success, the stent-migration and stent-occlusion rates were 3.6% and 3.0%, respectively. No AE-related mortality was reported. The methodological quality assessment showed the majority of the studies having low or unclear quality. Conclusion In this exploratory analysis, endoscopic PD drainage may be an effective and safe option in selected patients for the management of obstructive-type PC pain. However, a randomized–controlled trial is needed to delineate the role of this invasive practice.

Abstract
PURPOSE The eastern corridor of Africa is affected by a high burden of esophageal cancer (EC), with > 90% of patients presenting with advanced disease. Self-expanding metal stents (SEMS) have been previously reported as safe and effective for palliation of malignant dysphagia in resource-limited settings; however, access is limited throughout Eastern Africa. METHODS In response to demand for palliative interventions for patients with dysphagia because of EC, the African Esophageal Cancer Consortium (AfrECC) partnered with the Clinton Health Access Initiative to improve access to SEMS in Eastern Africa. We undertook a stepwise implementation approach to (1) identify barriers to SEMS access, (2) conduct a market analysis, (3) select an industry partner, (4) establish regulatory and procurement processes, (5) develop endoscopic training resources, (6) create a medical device registry, and (7) establish principles of accountability. RESULTS Following an evaluation of market demand and potential SEMS manufacturers, Boston Scientific Corporation announced its commitment to launch an access program to provide esophageal SEMS to patients in Tanzania, Kenya, Malawi, and Zambia at a subsidized price. Parallel regulatory and procurement processes were established in each participating country. Endoscopy training courses were designed and conducted, using the Training-of-Trainers model. A device registry was created to centralize data for quality control and to monitor channels of SEMS distribution. Principles of accountability were developed to guide the sustainability of this endeavor. CONCLUSION The AfrECC Stent Access Initiative is an example of a multisector partnership formed to provide an innovative solution to align regional needs with a supply chain for a high-priority medical device.

Abstract
Background and Aims Serial stent placement may be necessary during endoscopic interventions, but the passage of a guidewire alongside an initial stent can be challenging, time-consuming, and sometimes unsuccessful. We describe a modification of a cytology brush catheter to allow simultaneous placement of 2 guidewires to facilitate serial stent placement and demonstrate its application in different scenarios. Methods This is a retrospective series of 3 patients with different conditions (acute cholecystitis, pancreas pseudocyst, and severe biliary stricture) in whom placement of a second guidewire facilitated serial stent placement. A step-by-step demonstration of the technique is provided. Results Serial stent placement was successful in all patients without adverse events. Conclusions A modified cytology brush catheter can be used to deliver 2 guidewires simultaneously during ERCP and EUS procedures. This technique may improve procedural efficiency, maintain a safety track, and augment therapy in certain situations.

Abstract
BACKGROUND Gastrointestinal endoscopy (GIE) is not routinely accessible in many parts of rural Africa. As surgical training expands and technology progresses, the capacity to deliver endoscopic care to patients improves. We aimed to describe the current burden of gastrointestinal (GI) disease undergoing GIE by examining the experience of surgical training related to GIE. METHODS A retrospective review was conducted on GIE procedures performed by trainees with complete case logs during 5-year general surgery training at Pan-African Academy of Christian Surgeons (PAACS) sites. Cases were classified according to diagnosis and/or indication, anatomic location, intervention, adverse events, and outcomes. Comparisons were performed by institutional location and case volumes. Analysis was performed for trainee self-reported autonomy by post-graduate year and case volume experience. RESULTS Twenty trainees performed a total of 2181 endoscopic procedures. More upper endoscopies (N = 1,853) were performed than lower endoscopies (N = 325). Of all procedures, 546 (26.7%) involved a cancer or mass, 267 (12.2%) involved a report of blood loss, and 452 (20.7%) reported pain as a component of the diagnosis. Interventions beyond biopsy were reported in 555 (25%) procedures. Esophageal indications predominated the upper endoscopies, particularly esophageal cancer. Trainees in high-volume centers and in East Africa performed more interventional endoscopy and procedures focused on esophageal cancer. Procedure logs documented adverse events in 39 cases (1.8% of all procedures), including 16 patients (0.8%) who died within 30 days of the procedure. Self-reported autonomy improved with both increased endoscopy experience and post-graduate year. CONCLUSIONS GIE is an appropriate component of general surgery residency training in Africa, and adequate training can be provided, particularly in upper GI endoscopy, and includes a wide variety of endoscopic therapeutic interventions.

Abstract
BACKGROUND Discovery of methylated DNA markers (MDM) of esophageal squamous cell carcinoma (ESCC) has sparked interest in assessing these markers in tissue. We evaluated MDMs in ESCC from three geographically and ethnically distinct populations, and explored the feasibility of assaying MDMs from DNA obtained by swallowed balloon devices. METHODS MDMs were assayed in ESCC and normal tissues obtained from the populations of United States, Iran, and China, and from exfoliative cytology specimens obtained by balloons in a Chinese population. Areas under the receiver operating curve (AUC) of MDMs discriminating ESCC from normal tissues were calculated. Random forest prediction models were built, trained on U.S. cases and controls, and calibrated to U.S.-only controls (model 1) and three-country controls (model 2). Statistical tests were used to assess the relationship between dysplasia and MDM levels in balloons. RESULTS Extracted DNA from 333 ESCC and 322 normal tissues was analyzed, in addition to archival DNA from 98 balloons. For ESCC, model 1 validated in Iranian and Chinese tissues with AUCs of 0.90 and 0.87, and model 2 yielded AUCs of 0.99, 0.96, and 0.94 in tissues from the United States, Iran, and China, respectively. In Chinese balloons, MDMs showed a statistically significant trend of increasing levels with increasing grades of dysplasia (P < 0.004). CONCLUSIONS MDMs accurately discriminate ESCC from normal esophagus in tissues obtained from high- and low-incidence countries. Preliminary data suggest that levels of MDMs assayed in DNA from swallowed balloon devices increase with dysplasia grade. Larger studies are needed to validate these results. IMPACT MDMs coupled with minimally invasive collection methods have the potential for worldwide application in ESCC screening.

Abstract
BACKGROUND AND AIMS Presence of malignant regional lymph nodes (MRLNs) precludes curative oncological resection or liver transplantation for cholangiocarcinoma (CCA). Limited data support the utility of endoscopic ultrasound (EUS)/fine needle aspiration (FNA) for detection of MRLNs in extrahepatic CCA, but there are no data for its role in intrahepatic CCA (iCCA). The aim of this study is to evaluate the staging impact of EUS for CCA, including analysis by subtype. APPROACH AND RESULTS We identified consecutive patients with CCA who underwent EUS staging at a single tertiary care center from October 2014 to April 2018. Among this cohort, we abstracted clinical demographic, radiographical, procedural, cytopathological, and surgical data. STATA 15 software was used for comparative analysis calculations (StataCorp LP, College Station, TX). The study cohort included 157 patients; 24 (15%), 124 (79%), and 9 (6%) with intrahepatic, perihilar, and distal CCA, respectively. EUS was able to identify regional lymph nodes (RLNs) in a higher percentage of patients compared to cross-sectional imaging (86% vs. 47%; P < 0.001). FNA was performed in 133 (98.5%) patients with RLNs, with a median of three passes per node. EUS-FNA identified MRLN in 27 of 31 (87.1%) patients ultimately found to have MRLNs. For iCCA, EUS detected a higher percentage of RLN compared to cross-sectional imaging (83% vs. 50%; P = 0.048), with MRLNs identified in 4 (17%) patients. Among the entire cohort, identification of at least one MRLN by EUS was associated with lower median survival (353 vs. 1,050 days; P < 0.001) and increased risk of death (hazard ratio = 4.1; P < 0.001). CONCLUSIONS EUS-FNA is effective for identifying MRLN in patients with CCA, and should be routinely incorporated into staging of all CCA subtypes given the impact of MRLN on prognosis and management decisions.

METHODS Consecutive patients undergoing ERGD or PC for AC from January 2007 to October 2018 were included. Primary outcome was the rate of conversion to open cholecystectomy and perioperative complications in groups. RESULTS The study included 52 patients with ERGD and 140 with PC prior to cholecystectomy (median 68 days [IQR: 47-105.5]). Technical success was higher in the PC group (100% vs 91%; P = 0.0004). There was a nonsignificant trend to lower postoperative complications with ERGD (30.7% vs 43.5%; P = 0.07). No difference in conversion to open cholecystectomy OR: 1.5 (95% CI: 0.68-3.65; P = 0.28) or severity of complications (Clavien-Dindo grade >2) OR: 0.60, (95% CI: 0.19-1.87; P = 0.38) was noted between the ERGD and PC groups. PC was associated with higher rates of unplanned repeat intervention (16.4% vs 7.7%; P = 0.02). CONCLUSION ERGD is suitable for patients with AC who is candidates for delayed cholecystectomy and should be considered for gallbladder drainage in patients with concomitant choledocholithiasis or cholangitis who require ERCP.

Abstract
BACKGROUND & AIMS Precursors of pancreatic cancer arise in the ductal epithelium; markers exfoliated into pancreatic juice might be used to detect high-grade dysplasia (HGD) and cancer. Specific methylated DNA sequences in pancreatic tissue have been associated with adenocarcinoma. We analyzed these methylated DNA markers (MDMs) in pancreatic juice samples from patients with pancreatic ductal adenocarcinomas (PDACs) or intraductal papillary mucinous neoplasms (IPMNs) with HGD (cases), and assessed their ability to discriminate these patients from individuals without dysplasia or with IPMNs with low-grade dysplasia (controls). METHODS We obtained pancreatic juice samples from 38 patients (35 with biopsy-proven PDAC or pancreatic cystic lesions with invasive cancer and 3 with HGD) and 73 controls (32 with normal pancreas and 41 with benign disease), collected endoscopically from the duodenum after secretin administration from February 2015 through November 2016 at 3 medical centers. Samples were analyzed for the presence of 14 MDMs (in the genes NDRG4, BMP3, TBX15, C13orf18, PRKCB, CLEC11A, CD1D, ELMO1, IGF2BP1, RYR2, ADCY1, FER1L4, EMX1, and LRRC4), by quantitative allele-specific real-time target and signal amplification. We performed area under the receiver operating characteristic curve analyses to determine the ability of each marker, and panels of markers, to distinguish patients with HGD and cancer from controls. MDMs were combined to form a panel for detection using recursive partition trees. RESULTS We identified a group of 3 MDMs (at C13orf18, FER1L4, and BMP3) in pancreatic juice that distinguished cases from controls with an area under the receiver operating characteristic value of 0.90 (95% CI, 0.83-0.97). Using a specificity cut-off value of 86%, this group of MDMs distinguished patients with any stage of pancreatic cancer from controls with 83% sensitivity (95% CI, 66%-93%) and identified patients with stage I or II PDAC or IPMN with HGD with 80% sensitivity (95% CI, 56%-95%). CONCLUSIONS We identified a group of 3 MDMs in pancreatic juice that identify patients with pancreatic cancer with an area under the receiver operating characteristic value of 0.90, including patients with early stage disease or advanced precancer. These DNA methylation patterns might be included in algorithms for early detection of pancreatic cancer, especially in high-risk cohorts. Further optimization and clinical studies are needed.

Abstract
BACKGROUND Pre-operative staging of pancreatic adenocarcinoma guides clinical decision making. Limited data indicate that metastasis to celiac ganglia (CG) correlates with poor prognosis. We investigated feasibility and safety of endoscopic ultrasound fine needle aspiration (EUS-FNA) detection of CG metastasis and its impact upon tumor stage, resectability, and survival in pancreatic ductal adenocarcinoma (PDAC). PATIENTS We reviewed our prospectively maintained EUS and cytopathology databases to identify patients with FNA proven CG metastasis in patients with PDAC from 2004 to 2017. Clinical demographics, EUS, CT, MRI, cytopathology, cancer stage, and resectability data were analyzed. Survival of PDAC patients with CG metastasis was compared to the expected survival of PDAC patients of similar stage as reported by the United States National Cancer Database. RESULTS Twenty-one patients with PDAC [median age 73 (IQR63-78); 14 (67%) female)], had CG metastasis confirmed by cytopathologic assessment. CG metastasis resulted in tumor upstaging relative to other EUS findings and cross sectional imaging findings in 12 (57%) and 15 (71%) patients, and converted cancers from resectable to unresectable relative to EUS and cross sectional imaging in 7 (37%) and 7 (37%) patients, respectively. In patients with PDAC, the survival of patients with CG metastasis was not significantly different from the overall survival (hazard ratio 0.71; 95% confidence interval 0.44, 1.13; p = 0.15). CONCLUSIONS EUS-FNA may safely identify CG metastases. While CG metastasis upstaged and altered the resectability status among this cohort of patients with PDAC, the survival data with regard to PDAC suggest that this may be misguided.

Abstract
OBJECTIVES In this study, we aim to assess the diagnostic utility of elevated serum IgG4 (sIgG4) concentration alone and in combination with peripheral eosinophilia (PE) for IgG4-related disease (IgG4-RD). METHODS From the Mayo Clinic, Rochester electronic medical record database we identified 409 patients with above normal levels of sIgG4 (reference range 121-140 mg/dL) who had sIgG4 measured to differentiate IgG4-RD from another disease. RESULTS Among 409 patients with any elevation in sIgG4 levels, 129 (31.5%) had a definite diagnosis of IgG4-RD. The prevalence of PE increased with increasing sIgG4 levels and was more likely to be seen in subjects with IgG4-RD vs. non-IgG4-RD at ≥1X (n = 35/120, 29.2% vs. n = 23/258, 8.9%; p < 0.001), ≥2X (n = 23/64, 35.9% vs. n = 5/54,9.3%; p = 0.001) and ≥3X (n = 18/42, 42.9% vs. n = 0/9, 0%; p = 0.015) of sIgG4 upper limit of normal (ULN), respectively. After adjusting for gender and age, sIgG4 levels ≥ 2X ULN with PE as a predictor, had a higher positive predictive value in predicting IgG4-RD (72.2% vs. 65.9%) with an Area Under the Receiver Operatic Characteristic Curve (AUC) of 0.776, compared to sIgG4 ≥ 2X ULN without PE predictor (AUC = 0.74), p = 0.016. PE, sIgG4≥2X ULN, male gender, and age independently predicted the disease with odds ratio of 4.89 (95% CI:2.51-9.54), 3.78 (95% CI:2.27-6.28), 2.78 (95% CI:1.55-4.97), and 1.03 (95% CI:1.02-1.05), respectively. CONCLUSION Even in subjects in whom IgG4-RD is suspected, only a minority (∼30%) with elevated sIgG4 levels have IgG4-RD. sIgG4 by itself is more specific at higher levels, though never diagnostic. PE increases with increasing sIgG4 and adds diagnostic value at higher sIgG4 levels.

Abstract
BACKGROUND AND AIMS Diagnostic tools for nonalcoholic fatty liver disease (NAFLD) detection and prognostication are limited, with histology remaining the criterion standard. We evaluated the feasibility and safety of EUS-guided liver biopsy (EUS-LB) sampling in NAFLD staging. METHODS In a prospective cohort of NAFLD patients with steatohepatitis and early liver fibrosis based on magnetic resonance elastography (MRE), EUS-LB sampling procedures were performed using a 22-gauge fork-tip core biopsy needle. Samples were evaluated by a blinded pathologist. Total aggregate sample length (TASL), number of complete portal triads, ability to calculate NAFLD activity score, ability to stage liver fibrosis, and ability to provide enough core liver tissue for lipidomics analysis were evaluated. Performance of EUS-LB sampling was compared with MRE. RESULTS Forty-one EUS-LB samples were obtained. The median TASL was 2.4 cm (interquartile range, 2.00-2.75). The median number of complete portal triads per TASL was 26 (interquartile range, 7-62). Of the samples, 100% were adequate to convey NAFLD activity score and fibrosis stage. All samples provided enough core liver tissue to allow the application of lipidomics testing. A significant positive linear association between EUS-LB sampling-detected fibrosis and MRE-detected fibrosis was observed (r = .469, P < .005). Compared with MRE, EUS-LB sampling established early fibrosis in 13 cases that MRE classified as normal. EUS-LB sampling-related adverse events occurred in 7% and were restricted to postprocedural pain. CONCLUSIONS EUS-LB sampling is a viable technique for full NAFLD evaluation and may be superior to MRE in establishing the diagnosis of nonalcoholic steatohepatitis with early fibrosis.

Abstract
Background and study aim The role of esophageal overtubes in upper gastrointestinal endoscopic suturing is unknown. This study aimed to determine whether overtube use was associated with technical success or adverse events. Patients and methods A retrospective review of consecutive patients who underwent endoscopic suturing for various indications was performed. Results A total of 719 patients underwent endoscopic suturing for various indications, including endoscopic bariatric procedures in 262, stent fixation in 258, defect closure in 190, and hemostasis in nine. An overtube was used in 186 procedures (25.9 %). Technical success was achieved in all cases. Minor mucosal trauma occurred in 15 cases (8.1 %) with use of an overtube, and none without an overtube ( P < 0.0001). No full-thickness esophageal perforation or hemorrhage related to overtube use or the suturing device occurred. Conclusions Endoscopic suturing can be performed safely for a variety of indications, including endoscopic bariatric procedures, defect repair, and stent fixation without an esophageal overtube. Minor esophageal mucosal trauma and equipment cost are increased when an overtube is used.

Abstract
BACKGROUND There is lack of consensus on post-operative surveillance for resected non-invasive intraductal papillary neoplasms (IPMNs). In this study we explored risk factors for subsequent PC in patients with MD-IPMN undergoing partial pancreatectomy. METHODS We searched the Mayo Clinic surgical pathology database for all cases of resected MD-IPMN between 1997 and 2014. Cases with histologically confirmed main pancreatic duct involvement either isolated or in a mixed pattern with branch-duct involvement were included. Outcomes of PC in the remnant pancreas, and death related to MD-IPMN were assessed with survival analyses (Kaplan-Meier and Cox regression). RESULTS Among the 179 patients with resected MD-IPMN the incidence of concomitant PC and high-grade dysplasia (HGD) in the resected specimen was 23 and 14%, respectively. The mean duration of follow-up was 4.31 years (range 0.12-13.5 years). Excluding 28 subjects who either underwent initial total pancreatectomy or partial pancreatectomy with surgical margins positive for PC/HGD, the 5-year incidence of subsequent PC was 12%, including 60.6% and 15.6% in those with initial PC and HGD, respectively. The 10-year incidence of PC was 21.2% overall, 60.6% for PC, 38.3% for HGD, and 3.0% for LGD. Risk of subsequent PC was significantly higher for those with initial PC compared with HGD (HR = 4.95, 95% CI: 1.63-15.03, p = 0.005 and for HGD compared with LGD (HR = 11.30, 95% CI: 1.55-82.26, p = 0.017). CONCLUSIONS Patients with MD-IPMN with PC or HGD undergoing segmental pancreatectomy are at higher risk of subsequent PC and may benefit from post-operative surveillance. The post-operative surveillance intervals in resected MD-IPMNs need to be tailored based on dysplasia grade.

Abstract
BACKGROUND & AIMS Pancreatic cancer produces debilitating pain that opioids often ineffectively manage. The suboptimal efficacy of celiac plexus neurolysis (CPN) might result from brief contact of the injectate with celiac ganglia. We compared the effects of endoscopic ultrasound-guided celiac ganglia neurolysis (CGN) vs the effects of CPN on pain, quality of life (QOL), and survival. METHODS We performed a randomized, double-blind trial of patients with unresectable pancreatic ductal adenocarcinoma and abdominal pain; 60 patients (age 66.4±11.6 years; male 66%) received CPN and 50 patients (age 66.8±10.0 years; male 56%) received CGN. Primary outcomes included pain control and QOL at week 12 and survival (overall median and 12 months). Secondary outcomes included morphine response, performance status, secondary neurolytic effects, and adverse events. RESULTS Rates of pain response at 12 weeks were 46.2% for CGN and 40.4% for CPN (P = .84). There was no significant difference in improvement of QOL between the techniques. The median survival time was significantly shorter for patients receiving CGN (5.59 months) compared to (10.46 months) (hazard ratio for CGN, 1.49; 95% CI, 1.02-2.19; P = .042), particularly for patients with non-metastatic disease (hazard ratio for CGN, 2.95; 95% CI, 1.61-5.45; P < .001). Rates of survival at 12 months were 42% for patients who underwent CPN vs 26% for patients who underwent CGN. The number of adverse events did not differ between techniques. CONCLUSION In a prospective study of patients with unresectable pancreatic ductal adenocarcinoma and abdominal pain, we found CGN to reduce median survival time without improving pain, QOL, or adverse events, compared to CPN. The role of CGN must be therefore be reassessed. Clinicaltrials.gov no: NCT01615653.

Abstract
BACKGROUND The sentinel acute pancreatitis event (SAPE) hypothesis for pathogenesis of chronic pancreatitis (CP) postulates that acute pancreatitis (AP), especially recurrent AP (RAP), precedes development of CP. However, in a recent population-based study, 52/89 (58.4%) of CP had no prior episodes of AP. In a large clinic-based CP cohort, we aimed to determine the incidence and timing of prior AP in patients diagnosed with CP. METHODS We retrospectively identified 499 consecutive patients with classic CP diagnosed at our institution from January 2013 through December 2015. We abstracted their demographic and clinical data, especially regarding prior AP. RESULTS We identified 3 cohorts: 1) CP with no AP (n = 231 [46.3%]), 2) AP before CP (n = 250 [50.1%]), and 3) AP after CP (n = 18 [3.6%]). At CP diagnosis, 249 patients (49.9%) had no prior AP. Compared with the "CP preceded by AP" cohort, the "CP without AP"' cohort was older (59.2 ± 13.9 vs 48.6 ± 15.7 years; P < .001), had a higher prevalence of diabetes mellitus (30.3% vs 12.4%; P < .001), reported less pain (52.8% vs 87.6%; P < .001), and had a lower rate of endoscopic interventions (16.0% vs 39.2%; P < .001). In the "CP preceded by AP" cohort, 117 (46.8%) had a single episode of AP and 133 (53.2%) had RAP. CONCLUSION Nearly half the patients with classic CP did not have prior AP. Only a quarter of patients had CP that could potentially have evolved from prior RAP. Development of CP may be attributable to an altogether different pathogenesis (a non-SAPE pathway) for a considerable proportion of patients.

Abstract
BACKGROUND Thiamin deficiency is a major public health concern in several low- and middle-income countries (LMICs)-current attention to the problem is lacking. AIM This review discusses prevalence of thiamin insufficiency and thiamin-deficiency disorders (TDDs) in LMICs, outlines programmatic experience with thiamin interventions, and offers recommendations to improve public-health and research attention to thiamin in LMICs. DISCUSSION Thiamin insufficiency, i.e. low-blood-thiamin status, is endemic among several Southeast Asian countries: Cambodia (70-100% of infants and 27-100% of reproductive-age women); Laos (13% of hospitalized infants); Thailand (16-25% of children and 30% of elderly adults). Thiamin deficiency accounts for up to 45% of under-5 deaths in Cambodia, 34% of infant deaths in Laos, and 17% of infant deaths in Myanmar. Deficiency also exists in Africa, Asia, and the Americas, but these instances have typically been isolated. Exclusively breastfed infants of thiamin-deficient mothers are at highest risk for TDD and related death. Intervention strategies that have been employed to combat thiamin deficiency include food processing, fortification, supplementation, dietary diversification, and dietary behaviors, all of which have shown varying levels of effectiveness. CONCLUSIONS We recommend universal thiamin-fortification of context-specific staple-foods in LMICs as a promising solution, as well as thiamin supplementation, particularly for pregnant and lactating women. Food processing regulations, dietary diversification, and modification of dietary behaviors to increase consumption of thiamin-rich foods may provide benefits in some circumstances, especially in countries without universal fortification programs or in populations dependent on food aid.

Abstract
BACKGROUND & AIMS Endoscopic ultrasound (EUS) allows visualization of celiac lymph nodes (CLNs) and celiac ganglia (CG). Reliably distinguishing these structures is important for tumor staging and CG ablative therapies. We aimed to evaluate the accuracy of EUS in distinguishing CLNs from CG using a strict cytopathology reference standard. We also determined the rate of detection of CLN and CG by conventional cross-sectional imaging. METHODS From EUS and cytopathology databases, we identified all patients who underwent EUS-FNA of a presumed CLN or CG from October 1, 2004, through March 1, 2017, and compared the findings with those from cytology (reference standard). Indeterminate cytology results were re-reviewed. EUS imaging (ie, index test) results were compared with those from the reference standard. An expert radiologist re-reviewed computed tomography and magnetic resonance images from 100 lesions, from 94 randomly selected patients with a reference standard, to determine the rates of CLN and CG detection. RESULTS A total of 504 patients (mean age, 63.4 ± 13.2 years; 292 men) underwent a median of 7 EUS-FNA passes (range, 1-13) for a total of 566 lesions perceived to be either a CLN or CG; the cytology reference standard was available for 521 lesions (92.1%). When we excluded indeterminate cytology results, the EUS accurately identified 281/286 CLNs (98.3%) and 166/186 CGs (89.2%), for an overall accuracy of 447/472 (94.7%). EUS-FNA distinguished CG from CLNs with a 93.3% sensitivity, 93.7% specificity, a positive predictive value of 96.2%, and a negative predictive value of 89.2%. Of 100 lesions in 94 patients randomly selected for a second expert radiology review, computed tomography and magnetic resonance imaging detected 59/67 CLNs (88.1%) and 13/33 CG (39.4%). CONCLUSION EUS accurately distinguishes CLNs from CG. EUS might therefore be used to increase the accuracy of tumor staging, to select tumor stage-appropriate therapy, and to guide CG-ablative therapies.

Abstract
BACKGROUND & AIMS IgG4-related disease (IgG4-RD), a multi-organ fibroinflammatory syndrome, typically responds to steroids. However, some cases are steroid resistant, and pancreaticobiliary IgG4-RD commonly relapses after steroid withdrawal. Rituximab induces remission of IgG4-RD, but the need for and safety of maintenance rituximab treatment are unknown. We compared outcomes of patients with pancreaticobiliary IgG4-RD treated with or without maintenance rituximab therapy. METHODS We performed a retrospective study of patients with pancreaticobiliary IgG4-RD treated with rituximab at the Mayo Clinic in Rochester, Minnesota, from January 2005 through December 2015. The cohort was divided into patients who received only rituximab induction therapy (group 1, n = 14) and patients who received rituximab induction followed by maintenance therapy (group 2, n = 29). We collected data on recurrence of IgG4-RD symptoms and findings, as well as information on evaluations, treatment, and adverse events. RESULTS Median follow-up times were similar between group 1 (34 mo) and group 2 (27 mo) (P = .99). Thirty-seven patients (86%) were in steroid-free remission 6 months after rituximab initiation. A higher proportion of patients in group 1 had disease relapse (3-year event rate, 45%) than in group 2 (3-year event rate, 11%) (P = .034). Younger age, higher IgG4 responder index score after induction therapy, and increased serum levels of alkaline phosphatase at baseline or after rituximab induction were associated with relapse. Infections developed in 6 of 43 patients, all in group 2 (P = .067 vs group 1); all but 1 occurred during maintenance therapy. CONCLUSIONS In a retrospective study of patients with pancreaticobiliary IgG4-RD, we found rituximab maintenance therapy prolongs remission. Relapses are uncommon among patients receiving maintenance therapy, but maintenance therapy may increase risk of infection. Patients with factors that predict relapse could be candidates for rituximab maintenance therapy.

Abstract
AIM To determine if end-stage renal disease (ESRD) is a risk factor for post endoscopic retrograde cholangiopancreatography (ERCP) adverse events (AEs).
METHODS We performed a retrospective cohort study using the Nationwide Inpatient Sample (NIS) 2011-2013. We identified adult patients who underwent ERCP using the International Classification of Diseases 9th Revision (ICD-9-CM). Included patients were divided into three groups: ESRD, chronic kidney disease (CKD), and control. The primary outcome was post-ERCP AEs including pancreatitis, bleeding, and perforation determined based on specific ICD-9-CM codes. Secondary outcomes were length of hospital stay, in-hospital mortality, and admission cost. AEs and mortality were compared using multivariate logistic regression analysis.
RESULTS There were 492175 discharges that underwent ERCP during the 3 years. The ESRD and CKD groups contained 7347 and 39403 hospitalizations respectively, whereas the control group had 445424 hospitalizations. Post-ERCP pancreatitis (PEP) was significantly higher in the ESRD group (8.3%) compared to the control group (4.6%) with adjusted odd ratio (aOR) = 1.7 (95%CI: 1.4-2.1, aP < 0.001). ESRD was associated with significantly higher ERCP-related bleeding (5.1%) compared to the control group 1.5% (aOR = 1.86, 95%CI: 1.4-2.4, aP < 0.001). ESRD had increased hospital mortality 7.1% vs 1.15% in the control OR = 6.6 (95%CI: 5.3-8.2, aP < 0.001), longer hospital stay with adjusted mean difference (aMD) = 5.9 d (95%CI: 5.0-6.7 d, aP < 0.001) and higher hospitalization charges aMD = $+82064 (95%CI: $68221-$95906, aP < 0.001).
CONCLUSION ESRD is a risk factor for post-ERCP AEs and is associated with higher hospital mortality. Careful selection and close monitoring is warranted to improve outcomes.

Abstract
Esophageal cancer is the eighth most common cancer worldwide and the sixth most common cause of cancer-related death; however, worldwide incidence and mortality rates do not reflect the geographic variations in the occurrence of this disease. In recent years, increased attention has been focused on the high incidence of esophageal squamous cell carcinoma (ESCC) throughout the eastern corridor of Africa, extending from Ethiopia to South Africa. Nascent investigations are underway at a number of sites throughout the region in an effort to improve our understanding of the etiology behind the high incidence of ESCC in this region. In 2017, these sites established the African Esophageal Cancer Consortium. Here, we summarize the priorities of this newly established consortium: to implement coordinated multisite investigations into etiology and identify targets for primary prevention; to address the impact of the clinical burden of ESCC via capacity building and shared resources in treatment and palliative care; and to heighten awareness of ESCC among physicians, at-risk populations, policy makers, and funding agencies.

Abstract
BACKGROUND Endoscopic sleeve gastroplasty (ESG) is a technique for managing mild to moderately obese patients. We aimed to evaluate the long-term outcomes, reproducibility, and predictors of weight response in a large multicenter cohort. METHODS Patients who underwent ESG between January 2013 and December 2015 in three centers were retrospectively analyzed. All procedures were performed using the Apollo OverStitch device (Apollo Endosurgery, Austin, TX). We performed per protocol (PP) and intention-to-treat (ITT) analyses, where patients lost to follow-up were considered failures. Multivariable linear and logistic regression analyses were performed. RESULTS We included 248 patients (mean age 44.5 ± 10 years, 73% female). Baseline BMI was 37.8 ± 5.6 kg/m2. At 6 and 24 months, 33 and 35 patients were lost to follow-up, respectively. At 6 and 24 months, %TBWL was 15.2 [95%CI 14.2-16.3] and 18.6 [15.7-21.5], respectively. Weight loss was similar between centers at both follow-up intervals. At 24 months, % of patients achieving ≥10% TBWL was 84.2 and 53% with PP and ITT analyses, respectively. On multivariable linear regression analysis, only %TBWL at 6 months strongly predicted %TBWL at 24 months (adjusted for age, gender, and baseline BMI, β = 1.21, p < 0.001). The odds of achieving ≥10%TBWL at 24 months if a patient achieved <10%TBWL at 6 months is 0.18 [0.034-0.84]. Five (2%) serious adverse events occurred. CONCLUSIONS ESG effectively induces weight loss up to 24 months in moderately obese patients. Failure to achieve adequate weight loss can be predicted early, and patients should be offered adjunctive therapies to augment it.

Abstract
BACKGROUND AND AIMS Symptomatic pancreatic walled-off necrosis (WON) may be managed by endoscopic transmural drainage and endoscopic transmural necrosectomy, with stent placement at endoscopic drainage sites. The optimal stent choice is yet to be determined. We compared outcomes after endoscopic management of WON using either large-caliber fully covered self-expandable metal stents (LC-SEMSs) or double-pigtail plastic stents (DPPSs). METHODS We performed a retrospective comparison of outcomes among patients who received LC-SEMSs or DPPSs before endoscopic transmural necrosectomy for WON. RESULTS Among 94 patients included, WON resolution rates did not differ between the DPPS (36 patients) and LC-SEMS (58 patients) groups, whether concomitant percutaneous drainage was considered a failure (75% vs 82.8%; P = .36) or not (91.7% vs 94.8%; P = .55). Of 75 patients (80%) successfully treated without percutaneous drainage, 37 (49%) underwent endoscopic transmural drainage without subsequent endoscopic transmural necrosectomy. WON was more likely to resolve without subsequent endoscopic transmural necrosectomy in the LC-SEMS group than the DPPS group (60.4% vs 30.8%; P = .01). WON resolution without subsequent endoscopic transmural necrosectomy remained more likely with LC-SEMSs (odds ratio, 4.5 [95% confidence interval, 1.5-15.5]) after adjusting for patient age and size and location of WON. Rates of adverse events were similar except for clinically significant bleeding requiring endoscopic intervention, which was higher with DPPSs than LC-SEMSs (14% vs 2%; P = .02). CONCLUSION Management of pancreatic WON with LC-SEMSs appears to decrease both the need for repeated necrosectomy procedures and the risk of intervention-related hemorrhage.

Abstract
Background Low serum selenium status has been associated with increased risk of esophageal squamous cell carcinoma (ESCC). East Africa is a region of high ESCC incidence and is known to have low soil selenium levels, but this association has not previously been evaluated. In this study we assessed the association of serum selenium concentration and the prevalence of esophageal squamous dysplasia (ESD), the precursor lesion of ESCC, in a cross-sectional study of subjects from Bomet, Kenya. Methods 294 asymptomatic adult residents of Bomet, Kenya completed questionnaires and underwent endoscopy with Lugol’s iodine staining and biopsy for detection of ESD. Serum selenium concentrations were measured by instrumental neutron activation analysis. Odds ratios (OR) and confidence intervals (95% CI) for associations between serum selenium and ESD were calculated using unconditional logistic regression. Results The mean serum selenium concentration was 85.5 (±28.3) μg/L. Forty-two ESD cases were identified (14% of those screened), including 5 (12%) in selenium quartile 1 (Q1), 5 (12%) in Q2, 15 (36%) in Q3, and 17 (40%) in Q4. Higher serum selenium was associated with prevalence of ESD (Q4 vs Q1: OR: 3.03; 95% CI: 1.05–8.74) and this association remained after adjusting for potential confounders (Q4 vs Q1: OR: 3.87; 95% CI: 1.06–14.19). Conclusion This is the first study to evaluate the association of serum selenium concentration and esophageal squamous dysplasia in an African population at high risk for ESCC. We found a positive association between higher serum selenium concentration and prevalence of ESD, an association contrary to our original hypothesis. Further work is needed to better understand the role of selenium in the etiology of ESCC in this region, and to develop effective ESCC prevention and control strategies.

Abstract
Background and study aims The preferred management of bleeding esophageal varices includes endoscopic band ligation. Endoscopic ligation devices (ELDs) are expensive and designed for single use, limiting their uptake in developing countries. We aimed to assess the efficacy of reprocessing ELDs using terminal microbial cultures and adenosine triphosphate (ATP) testing. Materials and methods ELDs were recovered after clinical use and their components (cap, handle, and cord) were subjected to reprocessing. This included manual cleaning, automated high-level disinfection (HLD), and drying with forced air. Using sterile technique, ELD components were sampled for ATP at three stages: before manual cleaning, after manual cleaning, and after HLD. Components were sent to an external laboratory for culturing. Cultures were interpreted as positive upon identification of Gram-negative bacilli. Results A total of 14 clinically used ELDs were studied, and 189 ATP tests and 41 cultures were evaluated. Overall, 95 % (39/41) of components and 86 % (12/14) of ELDs were culture-negative or did not yield Gram-negative bacilli. Two components (5 %; one handle and one cord) harbored Gram-negative bacilli in quantities of 1 CFU per component. There was no apparent correlation between ATP at any juncture of reprocessing and terminal cultures. Conclusions Reprocessing of ELDs is effective, resulting in infrequent and minimal microbial contamination. Microbial culturing can be used to ensure adequacy of ELD reprocessing if pursued. Until reusable ELDs are commercially available, continued efforts to better define the adequacy and long-term effects of reprocessing ELDs are needed.

Abstract
A workshop was sponsored by the National Institute of Diabetes and Digestive and Kidney Diseases to address the research gaps and opportunities in pancreatic EUS. The event occurred on July 26, 2017 in 4 sessions: (1) benign pancreatic diseases, (2) high-risk pancreatic diseases, (3) diagnostic and therapeutics, and (4) new technologies. The current state of knowledge was reviewed, with identification of numerous gaps in knowledge and research needs. Common themes included the need for large multicenter consortia of various pancreatic diseases to facilitate meaningful research of these entities; to standardize EUS features of different pancreatic disorders, the technique of sampling pancreatic lesions, and the performance of various therapeutic EUS procedures; and to identify high-risk disease early at the cellular level before macroscopic disease develops. The need for specialized tools and accessories to enable the safe and effective performance of therapeutic EUS procedures also was discussed.

Abstract
BACKGROUND AND AIMS Benign gastrointestinal (GI) strictures are often refractory to standard endoscopic interventions. Fully covered coaxial lumen-apposing metal stents (LAMS) have emerged as a novel therapy for these strictures. The aim of this study was to evaluate the safety and efficacy of LAMS for refractory GI strictures. PATIENTS AND METHODS A retrospective analysis was performed for patients who underwent LAMS placement for benign luminal strictures in three US centers between January 2014 and December 2016. The primary outcomes were technical success and initial clinical success of LAMS placement. Secondary outcomes were stent migration, rate of re-intervention, and adverse events. RESULTS A total of 49 patients underwent 56 LAMS placement procedures. Previous treatment had failed in 39 patients (79.6 %), and anastomotic strictures were the indication in 77.6 % (38/49), with the most common site being gastrojejunal (34.7 % [17/49]). Technical success was achieved in all procedures and initial clinical success was achieved in 96.4 % of all procedures (54/56). Patient initial clinical success was 95.9 % (47/49). Stent migration occurred in 17.9 % of procedures, and was more likely to occur at sites in the lower GI tract ( P = 0.02). The mean stent dwell time was 100.6 days, and the mean follow-up was 169.8 days. Minor adverse events, not requiring hospitalization, occurred in 33.9 % of procedures, including subsequent stricture progression (10.7 %). In cases where LAMS were removed, mean follow-up time was 102.2 days. The re-intervention rate was 75 % at 300 days follow-up after stent removal. Of the LAMS placed at anastomotic strictures, 36.4 % required re-intervention, with approximately two-thirds of these re-interventions requiring placement of a new stent or surgery. CONCLUSION LAMS placement was successful for the management of refractory GI strictures, with good technical and initial clinical success rates. However, re-intervention rates after LAMS removal were high, and many strictures were not resolved by an extended period of stenting with these coaxial stents. LAMS placement offers additional therapeutic options and in selected cases might be considered a destination therapy for patients with recalcitrant benign strictures.

Abstract
BACKGROUND AND AIMS Extension of ampullary adenomas into the common bile duct (CBD) or pancreatic duct (PD) may be difficult to treat endoscopically. We evaluated the feasibility, safety, and efficacy of endoscopic radiofrequency ablation (RFA) in the management of ampullary neoplasms with intraductal extension. METHODS This was a multicenter, retrospective analysis of all patients with intraductal extension of ampullary neoplasms treated with endoscopic RFA between February 2012 and June 2015. Treatment success was defined as the absence of detectable intraductal polyps by ductography, visual inspection, and biopsy sampling. RESULTS Fourteen patients with adenoma extension into the CBD (13 ± 7 mm, n = 14) and PD (7 ± 2 mm, n = 3) underwent a median of 1 RFA sessions (range, 1-5). Additional modalities (thermal probes, argon plasma coagulation, and/or photodynamic therapy) were also used in 7 patients, and prophylactic stents were routinely placed. Thirteen assessable patients underwent a median of 2 surveillance ERCPs after completion of treatment over a median follow-up of 16 months (range, 5-46), with intraductal biopsy specimens showing no neoplasm in 12 patients at the conclusion of endoscopic treatment. Treatment success was achieved in 92%, including 100% of those treated with RFA alone. Adverse events occurred in 43% and included ductal strictures (5 patients) and retroduodenal abscess (1 patient), all of which were successfully treated endoscopically. CONCLUSIONS Endoscopic RFA, alone or in combination with other modalities, may effectively treat intraductal extension of ampullary neoplasms. Ductal strictures were common after RFA but responded to endoscopic stent therapy. RFA may be appropriate in selected patients, particularly when the main treatment alternative is pancreaticoduodenectomy.

Abstract
BACKGROUND AND AIMS Malignant vascular invasion usually results from gross direct infiltration from a primary tumor and impacts cancer staging, prognosis, and therapy. However, patients may also develop a remote malignant thrombi (RMT), defined as a malignant intravascular thrombus located remote and noncontiguous to the primary tumor. Our aim was to compare EUS, CT, and magnetic resonance imaging (MRI) findings of RMT and to explore the potential impact on cancer staging. METHODS Patients with RMT were identified from a prospectively maintained EUS database. Retrospective chart review was performed to obtain EUS, CT/MRI, clinical, and outcome data. RESULTS A median of 3 FNAs (range, 1-8) was obtained from RMT in 17 patients (60 ± 14.1 years, 56% men) between April 2003 and August 2016, with the finding of malignant cytology in 12 patients (70.6%; 10 positive, 2 suspicious). CT/MRI detected the RMT in 5 patients (29.4%), 4 of whom had positive or suspicious EUS-FNA cytology. Among the 8 newly diagnosed pancreatic adenocarcinoma (PaC) patients, CT did not detect the RMT in 5 (63%), of whom 3 patients had positive or suspicious intravascular EUS-FNA cytology. For newly diagnosed PaC patients (n = 8), the EUS-FNA diagnosis of a biopsy specimen-proven RMT upstaged 3 patients (37.5%) and converted 2 patients (25%) from CT resectable to unresectable disease. No adverse events were reported. The mean follow-up was 18.9 ± 27.7 months. CONCLUSIONS Our study demonstrates the ability and potential safety of intravascular FNA to detect radiographically occult RMT, which substantially impacts cancer staging and resectability.
