Abstract
BACKGROUND Pancreatitis is a common surgical emergency, associated with pain and poor quality of life for patients. However, assessment of patient-reported outcome measures in these patients is unclear. This study aimed to identify and evaluate the methodological quality of the health-related quality of life instruments used for patients with acute or chronic pancreatitis. METHODS Prospective studies that evaluated health-related quality of life in acute or chronic pancreatitis were identified from systematic review of MEDLINE, EMBASE, and Web of Science until 28th June 2023 (PROSPERO: CRD42021274743). Instrument characteristics were extracted, and methodological quality assessed using COSMIN (COnsensus-based Standards for the selection of health status Measurement Instruments) guidelines and GRADE approach. Narrative synthesis was conducted, with recommendations for use based on COSMIN criteria, evaluated according to World Health Organisation (WHO) quality of life domains. RESULTS From 3850 records screened, 41 quality of life instruments were identified across 138 studies included. The majority (69.8%, n = 26) were designed to assess general health-related quality of life, whereas the remainder were abdominal-specific (n = 5) or pancreas-specific (n = 10). Only ten instruments (24.3%) demonstrated sufficient content validity, incorporating items in ≥5 WHO quality of life domains. However, only nine instruments (21.9%) incorporated public and patient involvement. Only the Gastrointestinal Quality of Life Index and PAN-PROMISE met the criteria to be recommended for use based on COSMIN methodological assessment. CONCLUSION There is significant heterogeneity in instruments used to assess quality of life after pancreatitis, with almost all instruments considered insufficient. Robust, validated, and relevant instruments are needed to better understand and determine appropriate interventions to improve quality of life for these patients.

Abstract
Chronic pancreatitis (CP) is a fibroinflammatory disease characterized by irreversible destruction of pancreatic tissue. With the development of the disease, it may lead to exocrine and/or endocrine insufficiency. CP is one of the common diseases that cause abdominal pain, which will not get permanent spontaneous relief as the disease evolves. The American College of Gastroenterology clinical guidelines recommend computed tomography or magnetic resonance imaging as the first-line examination for the diagnosis of CP. CP common imaging findings include pancreatic atrophy, irregular dilatation of the pancreatic duct, calcification of pancreatic parenchyma, pancreatic duct stones, etc. In clinical practice, whether any correlations between CP-induced abdominal pain patterns (no pain/constant/intermittent pain) and corresponding imaging findings present are not well known. Therefore, this review aims to comprehensively sort out and analyze the relevant information by collecting lots of literature on this field, so as to construct a cross-bridge between the clinical manifestations and imaging manifestations of CP patients. Also, it provides an imaging basis and foundation for the classification and diagnosis of abdominal pain types in clinical CP patients.

Abstract
BACKGROUND Acute and chronic pancreatitis constitute a continuum of inflammatory disease of the pancreas with an increasing incidence in most high-income countries. A subset of patients with a history of pancreatitis suffer from recurrence of acute pancreatitis attacks, which accelerate disease progression towards end-stage chronic pancreatitis with loss of exocrine and endocrine function. There is currently no available prophylactic treatment for recurrent acute pancreatitis apart from removing risk factors, which is not always possible. Pain is the primary symptom of acute pancreatitis, which induces the endogenous release of opioids. This may further be potentiated by opioid administration for pain management. Increased exposure to opioids leads to potentially harmful effects on the gastrointestinal tract, including, e.g. increased sphincter tones and decreased fluid secretion, which may impair pancreatic ductal clearance and elevate the risk for new pancreatitis attacks and accelerate disease progression. Peripherally acting µ-opioid receptor antagonists (PAMORAs) have been developed to counteract the adverse effects of opioids on the gastrointestinal tract. We hypothesize that the PAMORA naldemedine will reduce the risk of new pancreatitis attacks in patients with recurrent acute pancreatitis and hence decelerate disease progression. METHODS The study is a double-blind, randomized controlled trial with allocation of patients to either 0.2 mg naldemedine daily or matching placebo for 12 months. A total of 120 outpatients will be enrolled from five specialist centres in Denmark and Sweden. The main inclusion criteria is a history of recurrent acute pancreatitis (minimum of two confirmed pancreatitis attacks). The primary endpoint is time to acute pancreatitis recurrence after randomization. Secondary outcomes include changes in quality of life, gastrointestinal symptom scores, new-onset diabetes, exocrine pancreatic insufficiency, disease severity, health care utilization, adherence to treatment, and frequency of adverse events. Exploratory outcomes are included for mechanistic linkage and include the progression of chronic pancreatitis-related findings on magnetic resonance imaging (MRI) and changes in circulating blood markers of inflammation and fibrosis. DISCUSSION This study investigates if naldemedine can change the natural course of pancreatitis in patients with recurrent acute pancreatitis and improve patient outcomes.

Abstract
INTRODUCTION Pain is the most common symptom in acute pancreatitis (AP) and is among the diagnostic criteria. Therefore, we aimed to characterize acute abdominal pain in AP. METHODS The Hungarian Pancreatic Study Group prospectively collected multicentre clinical data on 1435 adult AP patients between 2012 and 2017. Pain was characterized by its intensity (mild or intense), duration prior to admission (hours), localization (nine regions of the abdomen) and type (sharp, dull or cramping). RESULTS 97.3% of patients (n = 1394) had pain on admission. Of the initial population with acute abdominal pain, 727 patients answered questions about pain intensity, 1148 about pain type, 1134 about pain localization and 1202 about pain duration. Pain was mostly intense (70%, n = 511/727), characterized by cramping (61%, n = 705/1148), mostly starting less than 24 h prior to admission (56.7%, n = 682/1202). Interestingly, 50.9% of the patients (n = 577/1134) had atypical pain, which means pain other than epigastric or belt-like upper abdominal pain. We observed a higher proportion of peripancreatic fluid collection (19.5% vs. 11.0%; p = 0.009) and oedematous pancreas (8.4% vs. 3.1%; p = 0.016) with intense pain. Sharp pain was associated with AP severity (OR = 2.481 95% CI: 1.550-3.969) and increased mortality (OR = 2.263, 95% CI: 1.199-4.059) compared to other types. Longstanding pain (>72 h) on admission was not associated with outcomes. Pain characteristics showed little association with the patient's baseline characteristics. CONCLUSION A comprehensive patient interview should include questions about pain characteristics, including pain type. Patients with sharp and intense pain might need special monitoring and tailored pain management. SIGNIFICANCE Acute abdominal pain is the leading presenting symptom in acute pancreatitis; however, we currently lack specific guidelines for pain assessment and management. In our cohort analysis, intense and sharp pain on admission was associated with higher odds for severe AP and several systemic and local complications. Therefore, a comprehensive patient interview should include questions about pain characteristics and patients with intense and sharp pain might need closer monitoring.

EUS pancreatic function testing and dynamic pancreatic duct evaluation for the diagnosis of exocrine pancreatic insufficiency and chronic pancreatitis. Gastrointest Endosc 2021; 93:444-453. [PMID: 32562609 PMCID: PMC8121049 DOI: 10.1016/j.gie.2020.06.029] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/27/2020] [Accepted: 06/05/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND AND AIMS EUS and endoscopic pancreatic function tests (ePFTs) may be used to diagnose minimal-change chronic pancreatitis (MCCP). The impact of evaluation for exocrine pancreatic insufficiency (EPI) and real-time assessment of EUS changes after intravenous secretin on the clinical diagnosis of MCCP is unknown. METHODS Patients with suspected MCCP underwent baseline EUS assessment of the pancreatic parenchyma and measurement of the main pancreatic duct (B-MPD) in the head, body, and tail. Human secretin 0.2 μg/kg was given intravenously followed 4, 8, and 12 minutes later by repeat MPD (S-MPD) measurements. Duodenal samples at 15, 30, and 45 minutes were aspirated to assess bicarbonate concentration. Endoscopists rated the percentage clinical likelihood of chronic pancreatitis (1) before secretin; (2) after secretin but before aspiration; and (3) after bicarbonate results. RESULTS A total of 145 consecutive patients (mean age, 44±13 years; 98 females) were diagnosed with EPI (n = 32; 22%) or normal exocrine pancreatic function (n = 131, 78%). S-MPD/B-MPD ratios in the tail 4 and 8 minutes after secretin were higher in the group with normal exocrine function. Ratios at other times, locations, and duodenal fluid volumes were similar between the 2 groups. A statistically significant change in the median percentage likelihood of chronic pancreatitis was noted after secretin in all groups. The sensitivity and specificity of EPI for the EUS diagnosis of chronic pancreatitis (≥5 criteria) were 23.4% (95% confidence interval, 12.3-38.0) and 78.6% (95% confidence interval, 69.1-86.2), respectively. CONCLUSION Real-time EUS findings and ePFTs have a significant impact on the clinical assessment of MCCP. The diagnosis of EPI shows poor correlation with the EUS diagnosis of MCCP.

Is Cambridge scoring in chronic pancreatitis the same using ERCP and MRCP?: A need for revision of standards. Abdom Radiol (NY) 2021; 46:647-654. [PMID: 32740862 DOI: 10.1007/s00261-020-02685-2] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2020] [Revised: 05/29/2020] [Accepted: 07/22/2020] [Indexed: 12/12/2022]
Abstract
PURPOSE Grading of chronic pancreatitis (CP) is a clinical and radiologic challenge. Retrograde cholangiopancreatography (ERCP) and magnetic resonance cholangiopancreatography (MRCP) use a version of the Cambridge criteria for ductal evaluation and CP staging, but interchangeability between the modalities lacks validation. This work compares ERCP and MRCP Cambridge scores and evaluates diagnostic performance of MRCP in a large cohort of patients with CP. METHODS A large radiology database was searched for CP patients who underwent MRCP between 2003 and 2013. Next, patients who also had an ERCP within 90 days of their MRCP were selected. These were categorized into mild, moderate, and severe CP using the standardized Cambridge classification for ERCP. Radiologists blinded to ERCP findings then rated MRCP with modified Cambridge scores. RESULTS The cohort comprised 325 patients (mean age 51 years; 56% female). By ERCP Cambridge classification, 122 had mild CP, 109 moderate CP, and 94 severe CP. MRCP and ERCP showed total agreement of Cambridge score in only 43% of cases. With ERCP as reference, the sensitivity and specificity of MRCP in detecting Cambridge scores 4 + 5 (main-duct predominant) were 75.9% and 64.3%, and for Cambridge score 3 (side-branch predominant) it was 60.0% and 76.9%, respectively. CONCLUSIONS There is a lack of strong concordance between ERCP- and MRCP-based grading of CP using the Cambridge criteria. MRCP had moderate to good performance in diagnosing side-branch predominant versus main-duct predominant CP. This suggests an inherent challenge in comparing literature and calls for a revision of the standards.

Abstract
OBJECTIVES In patients with chronic pancreatitis (CP), the aim was to explore the association between pancreatic morphological progression over four years and corresponding changes in disease characteristics, including quality of life (QOL), pain, and exocrine pancreatic function. METHODS Twenty-five patients with CP were followed by magnetic resonance imaging (MRI). Data were obtained at baseline and after 4-year follow-up, including clinical information, QOL, and pain as assessed by validated questionnaires. Morphological assessments were derived from the same MRI scanner and included pancreatic gland volume, apparent diffusion coefficient values, fat signal fraction, and main pancreatic duct diameter. RESULTS After four years, CP patients showed significant progression in morphological parameters of the pancreas, except for the ductal-related changes (p < .13). Hence, patients developed reduced pancreatic volume by 13.5% (p < .001), an increase of fibrosis by 10.8% (p < .001), and an increase of fat infiltration by 7.6% (p < .001). In contrast, the patient-reported outcomes of QOL and pain did not change significantly over four years (all p > .05). Moreover, the progression of morphological imaging findings was not related to changes in QOL, pain severity, and pain interference (all p > .05). There was, however, an association between the 4-year progression of pancreatic atrophy and the decrease in fecal elastase concentration (r = 0.61; p < .001). CONCLUSIONS Progression of gland morphology in CP did not correlate with changes in the quality of life or pain symptoms. Advanced pancreatic imaging techniques may be a highly sensitive tool for monitoring morphological disease progression, but do not directly reflect patients' disease burden.

Abstract
Chronic pancreatitis is a multifactorial, fibroinflammatory syndrome in which repetitive episodes of pancreatic inflammation lead to extensive fibrotic tissue replacement, resulting in chronic pain, exocrine and endocrine pancreatic insufficiency, reduced quality of life, and a shorter life expectancy. The incidence and prevalence of chronic pancreatitis is rising and no curative treatment is available. Using novel diagnostic algorithms, definitive chronic pancreatitis can be diagnosed by imaging criteria alone, whereas probable chronic pancreatitis requires clinical features and imaging criteria. Criteria for the diagnosis of early chronic pancreatitis are still under discussion and need prospective validation in clinical trials. Cross-sectional imaging should be used first; endoscopic ultrasound is needed only when CT or MRI are inconclusive or to plan therapeutic interventions. Management of chronic pancreatitis requires an interdisciplinary approach including primary care practitioners, gastroenterologists, surgeons, radiologists, pain specialists, and nutritional therapists. Patients with chronic pancreatitis should be seen at least once a year and re-evaluated for causal risk factors, symptom control, and complications such as malnutrition, pancreatic exocrine insufficiency, and diabetes; refer to a specialised centre if symptoms are poorly controlled or there is risk of deterioration. Scoring systems to monitor disease progression have been developed and validated internationally. Interventional treatments for pain or cholestasis should be done by specialists only, and early discussion of treatment approaches should include all medical disciplines involved in care. Throughout this Seminar, we address research needs such as staging of pancreatitis, aspects of malnutrition and pain, and cancer surveillance, to help improve the care of patients.

Abstract
PURPOSE This feasibility and validation study addresses the potential use of magnetic resonance imaging (MRI) texture analysis of the pancreas in patients with chronic pancreatitis (CP). METHODS Extraction of 851 MRI texture features from diffusion weighted imaging (DWI) of the pancreas was performed in 77 CP patients and 22 healthy controls. Features were reduced to classify patients into subgroups, and a Bayes classifier was trained using a tenfold cross-validation forward selection procedure. The classifier was optimized to obtain the best average m-fold accuracy, sensitivity, specificity, and positive predictive value. Classifiers were: presence of disease (CP vs. healthy controls), etiological risk factors (alcoholic vs. nonalcoholic etiology of CP and tobacco use vs. no tobacco use), and complications to CP (presumed pancreatogenic diabetes vs. no diabetes and pancreatic exocrine insufficiency vs. normal pancreatic function). RESULTS The best classification performance was obtained for the disease classifier selecting only five of the original features with 98% accuracy, 97% sensitivity, 100% specificity, and 100% positive predictive value. The risk factor classifiers obtained good performance using 9 (alcohol: 88% accuracy) and 10 features (tobacco: 86% accuracy). The two complication classifiers obtained similar accuracies with only 4 (diabetes: 83% accuracy) and 3 features (exocrine pancreatic function: 82% accuracy). CONCLUSION Pancreatic texture analysis demonstrated to be feasible in patients with CP and discriminate clinically relevant subgroups based on etiological risk factors and complications. In future studies, the method may provide useful information on disease progression (monitoring) and detection of biomarkers characterizing early-stage CP.

Combined extracorporeal shock wave lithotripsy and endoscopic treatment for pain in chronic pancreatitis (SCHOKE trial): study protocol for a randomized, sham-controlled trial. Trials 2020; 21:338. [PMID: 32299454 PMCID: PMC7164272 DOI: 10.1186/s13063-020-04296-0] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2019] [Accepted: 03/30/2020] [Indexed: 02/08/2023] Open
Abstract
Background Pain is the primary symptom of chronic pancreatitis (CP) and remains a considerable therapeutic challenge. In patients with obstruction of the pancreatic duct, including stones and strictures, endoscopic treatment with or without preceding extracorporeal shock wave lithotripsy (ESWL) has been used for pancreatic duct decompression. The rationale for these procedures is based on the assumption that obstruction of the pancreatic duct leads to ductal hypertension and pain. However, clinical pain symptoms correlate poorly with pancreatic duct morphology, and the evidence for pancreatic duct decompression as an effective treatment for pain is based on case series and comparison between different procedures. No randomized, prospective, sham-controlled trials are currently available. The SCHOKE (Extracorporeal Shock Wave Lithotripsy and Endotherapy for Pain in Chronic Pancreatitis) trial is a randomized, sham-controlled trial designed to determine if pancreatic duct decompression is an effective treatment for pain in patients with CP. Methods The SCHOKE trial is a randomized, single-blind, parallel-group, sham-controlled trial designed to evaluate the effect of combined ESWL and endoscopic treatment for pain in patients with CP. In total, 106 adult patients with painful CP and pancreatic duct obstruction will be randomized to combined ESWL and subsequent endoscopic treatment or corresponding sham procedures. The primary outcome is pain relief during the 3-month postrandomization period as documented in a pain diary. Secondary outcomes include quality of life and functional scores, patient global impression of change, change in use of analgesics, frequency of hospitalization, and complications. Standard follow-up is at 3 and 6 months after randomization. In an experimental substudy, quantitative sensory testing obtained before and after intervention will be used to obtain information on central pain processing and to develop models for prediction of treatment outcome. Discussion The SCHOKE trial investigates if pancreatic duct decompression, obtained by combined ESWL and endoscopic treatment, is effective for pain treatment in patients with CP.

Abstract
INTRODUCTION Chronic pancreatitis (CP) is thought to present the end stage of a continuous disease process evolving from acute pancreatitis (AP), over recurrent AP, to early and end-stage CP. Due to the irreversible nature of CP, early detection and prevention is key. Prospective assessment based on advanced imaging modalities as well as biochemical markers of inflammation, fibrosis and oxidative stress may provide a better understanding of the underlying pathological processes and help identify novel biomarkers of disease with the ultimate goal of early diagnosis, intervention and prevention of disease progression. This paper describes the protocol of a prospective multicentre cohort study investigating the fibroinflammatory process involved in progression from acute to CP using state-of-the-art diagnostic imaging modalities and circulating biomarkers of inflammation, fibrosis and oxidative stress. METHODS AND ANALYSIS Adult control subjects and patients at different stages of CP according to the M-ANNHEIM system will be recruited from outpatient clinics at the participating sites and form three cohorts: controls (n=40), suspected CP (n=60) and definitive CP (n=60). Included patients will be followed prospectively for 15 years with advanced MRI and contrast-enhanced endoscopic ultrasound with elastography, assessment of endocrine and exocrine pancreatic function, biochemical and nutritional assessment, and evaluation of pain processing using quantitative sensory testing. Blood samples for a biobank will be obtained. The purpose of the biobank is to allow analyses of potential circulating biomarkers of disease progression, including markers of inflammation, fibrosis and oxidative stress. ETHICS AND DISSEMINATION Permissions from the Regional Science Ethics committee and the Regional Data Protection Agency have been obtained. We will submit the results of the study for publication in peer-reviewed journals regardless of whether the results are positive, negative or inconclusive.

Abstract
AIM To assess the interobserver agreement of computed tomography (CT) reporting standards for chronic pancreatitis (CP). SUBJECTS AND METHODS Retrospective analysis of CT of 47 patients (33 males and 11 females, age range 36 to 56 years) with CP who presented with abdominal pain (n = 41), steatorrhea (n = 37), and glucose intolerance (n = 31). The patients underwent CT study using a 16-multidetector CT scanner with a pancreatic protocol including a nonenhanced scan followed by pancreatic phase at 35 s and portal venous phase at 65 s after intravenous injection of nonionic contrast medium. Image analysis was performed by two radiologists according to reporting standards for CP. RESULTS There was excellent interobserver agreement (84.8 %) between the two reviewers in CT reporting standards for CP (K = 0.80, 95 % CI 0.75-0.85, P = 0.001). There was good interobserver agreement for pancreatic duct (PD) caliber (K = 0.71, 95 % CI 0.56-0.87, P = 0.001), PD contour (K = 0.76, 95 % CI 0.61-0.91, P = 0.001), PD stricture (K = 0.070, 95 % CI 0.53-0.88, P = 0.001), and distribution of findings (K = 0.69, 95 % CI 0.51-0.86, P = 0.001). There was excellent interobserver agreement for intraductal calculi (K = 0.84, 95 % CI 0.68-0.98, P = 0.001), pancreatic calcifications (K = 0.86, 95 % CI 0.84-0.98, P = 0.001), and pancreatic diameter (K = 0.87, 95 % CI 0.75-0.99, P = 0.001). CONCLUSION CT reporting standards for CP is a reliable method for diagnosis of patients with CP.

Abstract
Cine cardiac MRI is generally accepted as the "gold-standard" for functional myocardial assessment. It only took a few years after the development of commercial MRI systems for functional cardiac imaging to be developed, with electrocardiogram (ECG)-gated cine imaging first reported in 1988. The function of the gastrointestinal (GI) tract is more complex to study compared to the heart. However, the idea of having a non-invasive tool to study the GI function that also allows the concurrent assessment of different aspects of this function has become more and more attractive in the gastroenterological field. This review summarises key literature of the last 5 years to describe the current status of MRI in respect to the evaluation of GI function, highlighting the gaps and challenges and the future prospects. As the clinical application of a new technique requires that its clinical utility is confirmed by demonstration of its ability to enable clinicians to make a diagnosis and/or predict the treatment response, this review also considers whether or not this has been achieved, and how MRI has been validated against techniques currently recognised as the gold standard in clinical practice.
