ABSTRACT
BACKGROUND/OBJECTIVES: No simple, accurate diagnostic tests exist for exocrine pancreatic insufficiency (EPI), and EPI remains underdiagnosed in chronic pancreatitis (CP). We sought to develop a digital screening tool to assist clinicians to predict EPI in patients with definite CP. METHODS: This was a retrospective case-control study of patients with definite CP with/without EPI. Overall, 49 candidate predictor variables were utilized to train a Classification and Regression Tree (CART) model to rank all predictors and select a parsimonious set of predictors for EPI status. Five-fold cross-validation was used to assess generalizability, and the full CART model was compared with 4 additional predictive models. EPI misclassification rate (mRate) served as primary endpoint metric. RESULTS: 274 patients with definite CP from 6 pancreatitis centers across the United States were included, of which 58 % had EPI based on predetermined criteria. The optimal CART decision tree included 10 variables. The mRate without/with 5-fold cross-validation of the CART was 0.153 (training error) and 0.314 (prediction error), and the area under the receiver operating characteristic curve was 0.889 and 0.682, respectively. Sensitivity and specificity without/with 5-fold cross-validation was 0.888/0.789 and 0.794/0.535, respectively. A trained second CART without pancreas imaging variables (n = 6), yielded 8 variables. Training error/prediction error was 0.190/0.351; sensitivity was 0.869/0.650, and specificity was 0.728/0.649, each without/with 5-fold cross-validation. CONCLUSION: We developed two CART models that were integrated into one digital screening tool to assess for EPI in patients with definite CP and with two to six input variables needed for predicting EPI status.

Using a systematic literature search of original articles published during 2023 in Gastrointestinal Endoscopy (GIE) and other high-impact medical and gastroenterology journals, the GIE Editorial Board of the American Society for Gastrointestinal Endoscopy compiled a list of the top 10 most significant topic areas in general and advanced GI endoscopy during the year. Each GIE Editorial Board member was directed to consider 3 criteria in generating candidate topics-significance, novelty, and impact on global clinical practice-and subject matter consensus was facilitated by the Chair through electronic voting and a meeting of the entire GIE Editorial Board. The 10 identified areas collectively represent advances in the following endoscopic spheres: GI bleeding, endohepatology, endoscopic palliation, artificial intelligence and polyp detection, artificial intelligence beyond the colon, better polypectomy and EMR, how to make endoscopy units greener, high-quality upper endoscopy, endoscopic tissue apposition and closure devices, and endoscopic submucosal dissection. Each board member was assigned a topic area around which to summarize relevant important articles, thereby generating this overview of the "top 10" endoscopic advances of 2023.

Young adults who have experienced recurrent acute pancreatitis and chronic pancreatitis as children or adolescents are vulnerable to poor follow-up and disease management during the transfer from the pediatric to adult healthcare system. Although formalized transition programs for young adults have been developed and described for other disease conditions, no such program has been described for young adults with pancreatic disease. This document is the first expert opinion outlining the important aspects of a transitional care and transfer program tailored to youth with recurrent acute and chronic pancreatitis. We emphasize the unique needs of these patients as they transfer to adult health care and the need for further research. The goal of improved transitional care and transfer is to enhance the services provided to adolescents/young adults with pancreatic disease in both healthcare settings and improve continuity of follow-up care.

BACKGROUND & AIMS: The aims of this study were to: (1) assess the performance of the Pancreatitis Activity Scoring System (PASS) in a large intercontinental cohort of patients with acute pancreatitis (AP); and (2) investigate whether a modified PASS (mPASS) yields a similar predictive accuracy and produces distinct early trajectories between severity subgroups. METHODS: Data was prospectively collected through the Acute Pancreatitis Patient Registry to Examine Novel Therapies In Clinical Experience (APPRENTICE) consortium (2015-2018) involving 22 centers from 4 continents. AP severity was categorized per the revised Atlanta classification. PASS trajectories were compared between the three severity groups using the generalized estimating equations model. Four mPASS models were generated by modifying the morphine equivalent dose (MED), and their trajectories were compared. RESULTS: A total of 1393 subjects were enrolled (median age, 49 years; 51% males). The study cohort included 950 mild (68.2%), 315 (22.6%) moderately severe, and 128 (9.2%) severe AP. Mild cases had the lowest PASS at each study time point (all P < .001). A subset of patients with outlier admission PASS values was identified. In the outlier group, 70% of the PASS variation was attributed to the MED, and 66% of these patients were from the United States centers. Among the 4 modified models, the mPASS-1 (excluding MED from PASS) demonstrated high performance in predicting severe AP with an area under the receiver operating characteristic curve of 0.88 (vs area under the receiver operating characteristic of 0.83 in conventional PASS) and produced distinct trajectories with distinct slopes between severity subgroups (all P < .001). CONCLUSION: We propose a modified model by removing the MED component, which is easier to calculate, predicts accurately severe AP, and maintains significantly distinct early trajectories.

BACKGROUND: Total pancreatectomy with islet autotransplantation (TPIAT) is a viable option for treating debilitating recurrent acute pancreatitis (RAP) and chronic pancreatitis (CP) in adults and children. No data is currently available regarding variation in approach to operation. METHODS: We evaluated surgical techniques, islet isolation and infusion approaches, and outcomes and complications, comparing children (n = 84) with adults (n = 195) enrolled between January 2017 and April 2020 by 11 centers in the United States in the Prospective Observational Study of TPIAT (POST), which was launched in 2017 to collect standard history and outcomes data from patients undergoing TPIAT for RAP or CP. RESULTS: Children more commonly underwent splenectomy (100% versus 91%, p = 0.002), pylorus preservation (93% versus 67%; p < 0.0001), Roux-en-Y duodenojejunostomy reconstruction (92% versus 35%; p < 0.0001), and enteral feeding tube placement (93% versus 63%; p < 0.0001). Median islet equivalents/kg transplanted was higher in children (4577; IQR 2816-6517) than adults (2909; IQR 1555-4479; p < 0.0001), with COBE purification less common in children (4% versus 15%; p = 0.0068). Median length of hospital stay was higher in children (15 days; IQR 14-22 versus 11 days; IQR 8-14; p < 0.0001), but 30-day readmissions were lower in children (13% versus 26%, p = 0.018). Rate of portal vein thrombosis was significantly lower in children than in adults (2% versus 10%, p = 0.028). There were no mortalities in the first 90 days post-TPIAT. CONCLUSIONS: Pancreatectomy techniques differ between children and adults, with islet yields higher in children. The rates of portal vein thrombosis and early readmission are lower in children.

BACKGROUND: Symptomatic Zenker's diverticulum management has evolved from an open intervention to an endoscopic management. At our center, both an otolaryngologist and a gastroenterologist are present in the operating room when treating these lesions. An intra-procedural consensus is reached to undergo either rigid endoscopy or flexible endoscopic diverticulotomy with ENT guidance. We evaluated the real-world efficacy with a cooperative gastroenterology-otolaryngology approach. METHODS: Single-center retrospective study of patients who underwent a cooperative endoscopic diverticulotomy by a gastroenterologist and otolaryngologist at Cleveland Clinic Florida between 2012 and 2019. Demographic and clinical data, intra-procedural findings/complications, post-procedural symptoms, recurrence rate, and reintervention variables were extracted. Patients included in the study were > 17 years old, with symptomatic confirmed typical single Zenker's diverticulum. RESULTS: 63 subjects were identified. Patients were predominantly males (63.5%) and white (84.1%), with mean age 73.5 years (53-95). Most subjects presented dysphagia (98.4%), mostly to solids (79.4%). Other demographic and clinical data are described in Table 1. The diverticula had a mean size of 36.3 mm. In 30.1% of the cases food debris was found during the procedure. The mean procedure length was 38.4 minutes. All cases were performed as outpatient. Technical success was achieved in all cases. Patients were followed for a mean of 3.24 months post-procedure. Clinical success was achieved in 92% subjects. One intra-procedural perforation was treated with endoclip. Table 1 Pre-procedural demographic and clinical variables in patients undergoing Zenker's diverticulum cooperative approach Variable Value (n = 63) Sex, n (%) Male Female 40 (63.5) 23 (36.5) Ethnicity/Race, n (%) Non-Hispanic White Hispanic Black 53 (84.1) 7 (11.1) 3 (4.8) Smoking status, n (%) Never Former Active 29 (46.0) 26 (41.3) 8 (10.7) Previous intervention for Zenker's diverticulum, n (%) 12 (19.1) Dysphagia, n (%) Only to solids Only to liquids Both solids and liquids 50 (79.4) 0 (0) 12 (19.0) Regurgitation of food, n (%) Chronic cough, n (%) 13 (20.6) Halitosis, n (%) 9 (14.3) CONCLUSION: A cooperative endoscopic approach by gastroenterology and otolaryngology for symptomatic Zenker's diverticulum management offered excellent technical and clinical success. This approach proved to be safe and effective.

BACKGROUND: Same-admission cholecystectomy (CCY) is recommended for mild acute biliary pancreatitis (biliary-AP). However, there is a paucity of research investigating reasons for early (30-day) unplanned readmissions in patients who undergo CCY for biliary-AP. Hence, we sought to investigate this gap using a large population database. METHODS: Using the Nationwide Readmission Database (2010-2014), we identified all adults (age ≥ 18 years) with a principal diagnosis of biliary-AP who had undergone CCY during the index hospitalization. Multivariable logistic regression models were obtained to assess independent predictors for 30-day readmission. Principal diagnosis for all readmissions was collected to ascertain the indications for early readmission. RESULTS: During the study period, 118,224 patients underwent same-admission CCY for biliary-AP. Three-fourths of all patients underwent invasive cholangiography during the hospitalization (intraoperative cholangiogram (IOC) = 57,038, ERCP = 31,500). The rate of early (30-day) readmission was 7.25% (n = 8574). Exacerbation of prior medical conditions (42.2%), sequelae of biliary-AP (resolving and recurrent pancreatitis, pseudocysts) (27.6%), surgical site and other postoperative complications (16%), choledocholithiasis and/or bile leak (9.6%), and preventable hospital-acquired conditions (4.6%) accounted for early readmissions. On multivariable analysis, predictors for readmission included male sex (odds ratio [OR] 1.18, 95% confidence interval [CI] 1.08-1.28), insurance type (Medicare insurance [OR 1.26, 95% CI 1.13-1.40]; Medicaid [OR 1.22, 95% CI 1.09-1.38]), outside-facility discharge (OR 1.35, 95% CI 1.16-1.57), severe AP (OR 1.35, 95% CI 1.21-1.50), and ≥ 3 Elixhauser comorbidities (OR 1.55, 95% CI 1.41-1.69). Performance of IOC (OR 0.90, 95% CI 0.82-0.97) and ERCP (OR 0.81, 95% CI 0.73-0.89) were associated with decreased risk of early readmission. CONCLUSION: In this study, using a national population database evaluating patients who underwent same-admission CCY after biliary-AP, we identified potentially modifiable risk factors and causes for early readmission as well as opportunities to improve clinical care.

BACKGROUND & AIMS: The prevalence and significance of digestive manifestations in coronavirus disease 2019 (COVID-19) remain uncertain. We aimed to assess the prevalence, spectrum, severity, and significance of digestive manifestations in patients hospitalized with COVID-19. METHODS: Consecutive patients hospitalized with COVID-19 were identified across a geographically diverse alliance of medical centers in North America. Data pertaining to baseline characteristics, symptomatology, laboratory assessment, imaging, and endoscopic findings from the time of symptom onset until discharge or death were abstracted manually from electronic health records to characterize the prevalence, spectrum, and severity of digestive manifestations. Regression analyses were performed to evaluate the association between digestive manifestations and severe outcomes related to COVID-19. RESULTS: A total of 1992 patients across 36 centers met eligibility criteria and were included. Overall, 53% of patients experienced at least 1 gastrointestinal symptom at any time during their illness, most commonly diarrhea (34%), nausea (27%), vomiting (16%), and abdominal pain (11%). In 74% of cases, gastrointestinal symptoms were judged to be mild. In total, 35% of patients developed an abnormal alanine aminotransferase or total bilirubin level; these were increased to less than 5 times the upper limit of normal in 77% of cases. After adjusting for potential confounders, the presence of gastrointestinal symptoms at any time (odds ratio, 0.93; 95% CI, 0.76-1.15) or liver test abnormalities on admission (odds ratio, 1.31; 95% CI, 0.80-2.12) were not associated independently with mechanical ventilation or death. CONCLUSIONS: Among patients hospitalized with COVID-19, gastrointestinal symptoms and liver test abnormalities were common, but the majority were mild and their presence was not associated with a more severe clinical course.

INTRODUCTION: Chronic cannabis use had been associated with hyperemesis. We sought to determine whether cannabis liberalization contributed to increased hospitalizations for hyperemesis. METHODS: Cannabis use and admissions for hyperemesis in legalized states were compared with those of nonlegalized states, before and after cannabis legalization, using state inpatient databases. RESULTS: From 2011 to 2015, cannabis use increased 2.2 times in legalized states and 1.8 times in nonlegalized states. The odds of presentation with hyperemesis were higher in 2015 compared with those of 2011 in all states. DISCUSSION: Recreational legalization may be contributing to rising cannabis use. Hospitalizations for hyperemesis have also increased but did not seem to be solely due to cannabis legalization.

INTRODUCTION: Acute pancreatitis (AP) occurs among patients with pancreas-sufficient cystic fibrosis (PS-CF) but is reportedly less common among patients with pancreas-insufficient cystic fibrosis (PI-CF). The incidence of AP may be influenced by cystic fibrosis transmembrane conductance regulator (CFTR) modulator use. We hypothesized that CFTR modulators would reduce AP hospitalizations, with the greatest benefit in PS-CF. METHODS: MarketScan (2012-2018) was queried for AP hospitalizations and CFTR modulator use among patients with CF. Multivariable Poisson models that enabled crossover between CFTR modulator treatment groups were used to analyze the rate of AP hospitalizations on and off therapy. Pancreas insufficiency was defined by the use of pancreas enzyme replacement therapy. RESULTS: A total of 10,417 patients with CF were identified, including 1,795 who received a CFTR modulator. AP was more common in PS-CF than PI-CF (2.9% vs 0.9%, P = 0.007). Overall, the observed rate ratio of AP during CFTR modulator use was 0.33 (95% confidence interval [CI] 0.10, 1.11, P = 0.07) for PS-CF and 0.38 (95% CI 0.16, 0.89, P = 0.03) for PI-CF, indicating a 67% and 62% relative reduction in AP hospitalizations, respectively. In a subset analysis of 1,795 patients who all had some CFTR modulator use, the rate ratio of AP during CFTR modulator use was 0.36 (95% CI 0.13, 1.01, P = 0.05) for PS-CF and 0.53 (95% CI 0.18, 1.58, P = 0.26) for PI-CF. DISCUSSION: CFTR modulator use is associated with a reduction in AP hospitalizations among patients with CF. These observational data support the prospective study of CFTR modulators to reduce AP hospitalizations among patients with CF.

BACKGROUND AND AIMS: Many patients undergoing total pancreatectomy with islet autotransplant (TPIAT) for severe, refractory chronic pancreatitis or recurrent acute pancreatitis have a history of endoscopic retrograde cholangiopancreatography (ERCP). Using data from the multicenter POST (Prospective Observational Study of TPIAT) cohort, we aimed to determine clinical characteristics associated with ERCP and the effect of ERCP on islet yield. METHODS: Using data from 230 participants (11 centers), demographics, pancreatitis history, and imaging features were tested for association with ERCP procedures. Logistic and linear regression were used to assess association of islet yield measures with having any pre-operative ERCPs and with the number of ERCPs, adjusting for confounders. RESULTS: 175 (76%) underwent ERCPs [median number of ERCPs (IQR) 2 (1-4). ERCP was more common in those with obstructed pancreatic duct (p = 0.0009), pancreas divisum (p = 0.0009), prior pancreatic surgery (p = 0.005), and longer disease duration (p = 0.004). A greater number of ERCPs was associated with disease duration (p < 0.0001), obstructed pancreatic duct (p = 0.006), and prior pancreatic surgery (p = 0.006) and increased risk for positive islet culture (p < 0.0001). Mean total IEQ/kg with vs. without prior ERCP were 4145 (95% CI 3621-4669) vs. 3476 (95% CI 2521-4431) respectively (p = 0.23). Adjusting for confounders, islet yield was not significantly associated with prior ERCP, number of ERCPs, biliary or pancreatic sphincterotomy or stent placement. CONCLUSIONS: ERCP did not appear to adversely impact islet yield. When indicated, ERCP need not be withheld to optimize islet yield but the risk-benefit ratio of ERCP should be considered given its potential harms, including risk for excessive delay in TPIAT.

Primary myocardial involvement of Diffuse Large B-Cell lymphoma is extremely rare, accounting for 0.5 % of all lymphomas. We report a 65-year-old male, presenting with an acute cardiac tamponade, which was drained. A pericardial window with myocardial biopsy was carried out, disclosing a diffuse large B cell lymphoma. He received 6 cycles of rituximab, cyclophosphamide, vincristine, and prednisone (R-CVP), without response. Finally, a palliative chemotherapy with gemcitabine plus oxaliplatin was prescribed.

Lipocalin-2 (LCN2) is a secreted molecule, expressed in various cell types, that is involved in the progression of numerous diseases and disorders. The biological functions and expression levels of LCN2 in diseases including pancreatic cancer, pancreatitis (acute and chronic), and diabetes mellitus, suggest the potential role of LCN2 as a biomarker and/or therapeutic target. However, findings on the role of LCN2 in pancreatic diseases have been contradictory. In pancreatic cancer and pancreatitis, LCN2 has been identified as a potential biomarker; increased expression levels in various biological specimens correlate with the presence of the disease and may be able to differentiate cancer and chronic pancreatitis from healthy subjects. LCN2 is also known to be an adipokine; it is upregulated in obesity and is a common co-factor in the development of pancreatic diseases. Emerging research suggests LCN2 is elevated in type 2 diabetes mellitus, but the exact role of LCN2 in this disease is not clear. In this review, we summarize research on LCN2 as it relates to pancreatic diseases, highlighting the discrepancies in the literature. By explaining and clarifying the role of LCN2 in these disorders, we aim to promote research in developing novel diagnostic and treatment strategies to reduce the burden of pancreatic diseases.

OBJECTIVES: The incidence rates of acute pancreatitis (AP) and the prevalence of class III obesity, and metabolic syndrome (MetS) are increasing in the US. Since class III obesity was associated with adverse clinical outcomes of AP, we sought to understand if the presence of metabolic comorbidities collectively recognized, as MetS were associated with worse clinical outcomes and increased health-care utilization. METHODS: The Nationwide Readmissions Database (NRD) (2010-2014) was reviewed to identify all adult subjects with a principal discharge diagnosis of AP. Inpatient mortality, severe AP (SAP), and 30-day readmissions were the primary outcomes analyzed. Propensity score weighted analyses were used to compare AP subjects with and without MetS and were further stratified by class III obesity status. RESULTS: MetS was associated with 12.91% (139,165/1,078,183) of all admissions with AP. Propensity score weighted analyses showed that MetS was associated with an increased proportion of SAP (OR 1.21, 95% CI 1.17, 1.25), but decreased mortality (OR 0.62, 95% CI 0.54, 0.70) and 30-day readmissions (OR 0.86, 95% CI 0.83, 0.89). Propensity score weighted analyses also revealed that class III obesity was independently associated with increased mortality in AP subjects with (OR 1.92, 95% CI 1.41, 2.61) and without MetS (OR 1.55, 95% CI 1.26, 1.92), and increased SAP in subjects with and without MetS. CONCLUSIONS: Class III obesity appears to be the primary factor associated with adverse clinical outcomes in subjects with MetS admitted with AP. This has significant implications for patient management and future research targeting AP.

BACKGROUND AND AIM: Despite higher rates of gallstones in patients with cirrhosis, there are no population-based studies evaluating outcomes of acute biliary pancreatitis (ABP). Therefore, we sought to evaluate the predictors of early readmission and mortality in this high-risk population. METHODS: We utilized the Nationwide Readmission Database (2011-2014) to evaluate all adults admitted with ABP. Multivariable logistic regression models were used to assess independent predictors for 30-day readmission, index admission mortality, and calendar year mortality. RESULTS: Among 184 611 index admissions with ABP, 4344 (2.4%) subjects had cirrhosis (1649 with decompensation). Subjects with cirrhosis, when compared with those without, incurred higher rates of 30-day readmission (20.9% vs 11.2%; P < 0.001), index mortality (2.0% vs 1.0%; P < 0.001), and calendar year mortality (4.2% vs 0.9%; P < 0.001). Decompensation in cirrhosis was associated with significantly fewer cholecystectomies (26.7% vs 60.2%; P < 0.001) and endoscopic retrograde cholangiopancreatographies (23.3% vs 29.9%; P < 0.001). Multivariate analysis revealed that severe acute pancreatitis (odds ratio [OR]: 14.8; 95% confidence interval [CI]: 5.3, 41.2), sepsis (OR: 12.6; 95% CI: 5.8, 27.4), and decompensation (OR: 3.1; 96% CI: 1.4, 6.6) were associated with increased index admission mortality. Decompensated cirrhosis (OR: 1.8; 95% CI: 1.1, 3.0) and 30-day readmission (OR: 5.6; 95% CI: 3.3, 9.5) were predictors of calendar year mortality. However, index admission cholecystectomy was associated with decreased 30-day readmissions (OR: 0.6; 95% CI: 0.4, 0.7) and calendar year mortality (OR: 0.44; 95% CI: 0.25, 0.78). CONCLUSIONS: The presence of cirrhosis adversely impacts hospital outcomes of patients with ABP. Among modifiable factors, index admission cholecystectomy portends favorable prognosis by reducing risk of early readmission and consequent calendar year mortality.

Cathepsin E (CTSE) is an intracellular, hydrolytic aspartic protease found to be expressed in cells of the immune and gastrointestinal systems, lymphoid tissues, erythrocytes, and cancer cells. The precise functions are not fully understood; however, various studies have investigated its numerous cell-type specific roles. CTSE expression has been shown to be a potential early biomarker for pancreatic ductal adenocarcinoma (PDAC). PDAC patients have low survival rates mostly due to the lack of early detection methods. CTSE-specific activity probes have been developed and tested to assist in tumor imaging and functional studies investigating the role of CTSE expression in PDAC tumors. Furthermore, a CTSE protease-specific, photodynamic therapy pro-drug was developed to explore its potential use to treat tumors that express CTSE. Since CTSE is expressed in pancreatic diseases that are risk factors for PDAC, such as pancreatic cysts and chronic pancreatitis, learning about its function in these disease types could assist in early PDAC detection and in understanding the biology of PDAC progression. Overall, CTSE expression and activity shows potential to detect PDAC and other pancreatic diseases. Further research is needed to fully understand its functions and potential translational applicability.

BACKGROUND AND AIMS: Acute biliary pancreatitis (ABP) is associated with increased rates of morbidity in pregnancy. Because there is a paucity of population-based studies evaluating ABP in pregnancy, we sought to investigate clinical outcomes in hospitalized pregnant women on a national level. METHODS: By using the Nationwide Readmission Database (2011-2014), we identified all women (age ≥18 years) with an index admission for ABP in the United States. Multivariate and propensity-score matched analyses were performed to evaluate the impact of pregnancy on the clinical outcomes of early readmission and severe acute pancreatitis (SAP) in ABP. RESULTS: There were 7787 hospitalizations for ABP in pregnant women during the study period. The rate of 30-day readmission was 16.26%; 57% of these early readmissions were due to adverse events of ABP. Compared with nonpregnant women with ABP, ERCP (21.1% vs 25.2%; P < .001) and cholecystectomy (52.8% vs 55.2%; P = .02) were performed less frequently during pregnancy. Propensity-score matched analysis revealed an increased risk of 30-day readmissions in pregnancy (odds ratio [OR], 1.96; 95% confidence interval [CI], 1.67-2.30), whereas there was no difference in the risk of SAP (OR, 1.09; 95% CI, 0.76-1.57). Multivariate analysis demonstrated that weekend admission (OR, 1.40; 95% CI, 1.10-1.79) and >1 week of hospitalization (OR, 1.75; 95% CI, 1.24-2.48) increased the risk of 30-day readmission, whereas ERCP (OR, 0.40; 95% CI, 0.27-0.57) and cholecystectomy (OR, 0.13; 95% CI, 0.10-0.18) reduced the odds of early readmission in pregnancy. CONCLUSIONS: Pregnant women with ABP less frequently undergo timely endoscopic biliary decompression and cholecystectomy. These modifiable factors can potentially lower early readmissions in pregnant women.

BACKGROUND/OBJECTIVES: Total pancreatectomy with islet autotransplantation (TPIAT) is considered for managing chronic pancreatitis in selected patients when medical and endoscopic interventions have not provided adequate relief from debilitating pain. Although more centers are performing TPIAT, we lack large, multi-center studies to guide decisions about selecting candidates for and timing of TPIAT. METHODS: Multiple centers across the United States (9 to date) performing TPIAT are prospectively enrolling patients undergoing TPIAT for chronic pancreatitis into the Prospective Observational Study of TPIAT (POST), a NIDDK funded study with a goal of accruing 450 TPIAT recipients. Baseline data include participant phenotype, pancreatitis history, and medical/psychological comorbidities from medical records, participant interview, and participant self-report (Medical Outcomes Survey Short Form-12, EQ-5D, andPROMIS inventories for pain interference, depression, and anxiety). Outcome measures are collected to at least 1 year after TPIAT, including the same participant questionnaires, visual analog pain scale, pain interference scores, opioid requirements, insulin requirements, islet graft function, and hemoglobin A1c. Health resource utilization data are collected for a cost-effectiveness analysis. Biorepository specimens including urine, serum/plasma, genetic material (saliva and blood), and pancreas tissue are collected for future study. CONCLUSIONS: This ongoing multicenter research study will enroll and follow TPIAT recipients, aiming to evaluate patient selection and timing for TPIAT to optimize pain relief, quality of life, and diabetes outcomes, and to measure the procedure's cost-effectiveness. A biorepository is also established for future ancillary studies.

BACKGROUND AND AIMS: Direct pancreas juice testing of bicarbonate, lipase, or trypsin after stimulation by secretin or cholecystokinin is used to determine exocrine function, a surrogate for diagnosing chronic pancreatitis (CP). Endoscopic pancreas function tests (ePFTs), where a peak bicarbonate concentration (PBC) ≥80 mEq/L in pancreas juice is considered normal, are now used more frequently. In this ePFT, aspirates start 35 minutes after secretin administration because pancreas output peaks 30 minutes after secretagogue administration. The performance of ePFT in a cohort of patients with a presumptive diagnosis of CP referred to a pancreas clinic for consideration of an intervention including total pancreatectomy and islet autotransplantation was studied, compared with EUS, ERCP, histology, and consensus diagnosis. The effect of sedation, narcotic use, aspirate volume, body mass index, age, and proton pump inhibitors (PPIs) on test performance is reported. METHODS: After a test dose, synthetic human secretin was administered intravenously, and 30 minutes later sedation was achieved with midazolam and fentanyl or propofol. A gastroscope was advanced to the major papilla where 4 continuous aspiration samples were performed at 5-minute intervals in sealed bottles. PBC ≥80 mEq/L was normal. RESULTS: Eighty-one patients had ePFTs from August 2010 through October 2015. Twenty-seven patients (33%) were diagnosed with CP. Eighteen of the 27 patients with CP and 1 of the 54 patients without CP had an abnormal ePFT, producing a sensitivity of 66% (95% CI, 46.0-83.5), specificity 98% (95% CI, 90.1-99.9), positive predictive value 94.7% (95% CI, 74-99.9), and negative predictive value 85.5% (95% CI, 74.2-93.1). ERCP and PBC concordance was generally poor, but none of the patients without CP had major EUS changes, and only 3 patients with a PBC <80 mEq/L had a normal EUS. The PBC was affected by narcotics and PPI use. CONCLUSION: A 20-minute ePFT after secretin administration had a marginal sensitivity for diagnosis of CP. The diagnosis of CP should not rely on a single study and certainly not a PFT. The duodenal aspirate volume did not correlate with the PBC, which contrasts with current secretin-enhanced MRCP knowledge; therefore, further studies on this subject are warranted. Neither type of sedation, BMI, nor age affected test performance. Narcotics and PPIs may affect the PBC, so borderline results should be interpreted with caution in these groups.
