Gallstones as a cause in presumed acute alcoholic pancreatitis: observational multicentre study. Br J Surg 2024; 111:znae107. [PMID: 38713609 DOI: 10.1093/bjs/znae107] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2024] [Revised: 02/21/2024] [Accepted: 04/07/2024] [Indexed: 05/09/2024]
Abstract
BACKGROUND Data on the incidence and clinical relevance of gallstones in patients with suspected acute alcoholic pancreatitis are lacking and are essential to minimize the risk of recurrent acute pancreatitis. The aim of this study was to assess the incidence of gallstones and the associated rate of recurrent acute pancreatitis in patients with presumed acute alcoholic pancreatitis. METHODS Between 2008 and 2019, 23 hospitals prospectively enrolled patients with acute pancreatitis. Those diagnosed with their first episode of presumed acute alcoholic pancreatitis were included in this study. The term gallstones was used to describe the presence of cholelithiasis or biliary sludge found during imaging. The primary outcome was pancreatitis recurrence during 3 years of follow-up. RESULTS A total of 334 patients were eligible for inclusion, of whom 316 were included in the follow-up analysis. Gallstone evaluation, either during the index admission or during follow-up, was performed for 306 of 334 patients (91.6%). Gallstones were detected in 54 patients (17.6%), with a median time to detection of 6 (interquartile range 0-42) weeks. During follow-up, recurrent acute pancreatitis occurred in 121 of 316 patients (38.3%), with a significantly higher incidence rate for patients with gallstones compared with patients without gallstones (59% versus 34.2% respectively; P < 0.001), while more patients with gallstones had stopped drinking alcohol at the time of their first recurrence (41% versus 24% respectively; P = 0.020). Cholecystectomy was performed for 19 patients with gallstones (36%). The recurrence rate was lower for patients in the cholecystectomy group compared with patients who did receive inadequate treatment or no treatment (5/19 versus 19/34 respectively; P = 0.038). CONCLUSION Gallstones were found in almost one in every five patients diagnosed with acute alcoholic pancreatitis. Gallstones were associated with a higher rate of recurrent pancreatitis, while undergoing cholecystectomy was associated with a reduction in this rate.

Clinical diagnosis of psychiatric comorbidities, performance of screening tests and pattern of psychotropic medication use in patients with chronic pancreatitis. Pancreatology 2024; 24:378-383. [PMID: 38423915 DOI: 10.1016/j.pan.2024.02.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/29/2023] [Revised: 01/30/2024] [Accepted: 02/16/2024] [Indexed: 03/02/2024]
Abstract
BACKGROUND Psychiatric comorbidity measured by screening instruments is common in patients with chronic pancreatitis (CP) but whether this accurately reflects clinical diagnosis of psychiatric comorbidity is unknown and the prevalence of psychotropic medication prescription in CP remains largely unexplored. METHODS Adult patients (≥18 years) with definite CP were enrolled and completed the Hospital Anxiety and Depression Scale (HADS). Demographics, clinical characteristics and medications were retrieved from case report forms and the electronic health record (EHR). Clinical diagnosis of depression or anxiety was determined by presence of ICD-10 code or inclusion in the patient's EHR problem list or treatment plan. Comparisons were made between patients with and without clinical psychiatric comorbidity. RESULTS Total of 81 patients (48, 59.3% male; mean age 57.6 ± 14.3 years) were included. Clinical diagnoses of anxiety and depression were each noted in 47 (58%) patients, with overlap in 42 (51.9%). Compared to clinical diagnoses, the sensitivity and specificity of a positive screen for anxiety (HADS >7) were 76.6% and 91.2%; for depression 55.3% and 88.2%. Patients with anxiety and/or depression were more frequently female (51.9% v 20.7%), younger (53.6 v 64.9 years), and had alcohol etiology (51.9% v 27.6%) (all p < 0.01). In those with psychiatric comorbidity, 42 (80.8%) were prescribed psychotropic medication, most commonly gabapentinoid (24, 57.1%), selective serotonin reuptake inhibitor (n = 22, 52.4%) or benzodiazepine (n = 20, 47.6%). CONCLUSIONS Psychiatric comorbidities are common among CP patients and many receive psychotropic medications. Further studies are needed to evaluate the impact of these medications on CP symptoms.

Revolutionizing the Pancreatic Tumor Diagnosis: Emerging Trends in Imaging Technologies: A Systematic Review. MEDICINA (KAUNAS, LITHUANIA) 2024; 60:695. [PMID: 38792878 PMCID: PMC11122838 DOI: 10.3390/medicina60050695] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/27/2024] [Revised: 04/19/2024] [Accepted: 04/21/2024] [Indexed: 05/26/2024]
Abstract
Background and Objectives: The pancreas, ensconced within the abdominal cavity, requires a plethora of sophisticated imaging modalities for its comprehensive evaluation, with ultrasonography serving as a primary investigative technique. A myriad of pancreatic pathologies, encompassing pancreatic neoplasia and a spectrum of inflammatory diseases, are detectable through these imaging strategies. Nevertheless, the intricate anatomical confluence and the pancreas's deep-seated topography render the visualization and accurate diagnosis of its pathologies a formidable endeavor. The objective of our paper is to review the best diagnostic imagistic tools for the pancreas. Materials and Methods: we have gathered several articles using Prisma guidelines to determine the best imagistic methods. The imperative of pancreatic scanning transcends its diagnostic utility, proving to be a pivotal element in a multitude of clinical specialties, notably surgical oncology. Within this domain, multidetector computed tomography (MDCT) of the pancreas holds the distinction of being the paramount imaging modality, endorsed for its unrivaled capacity to delineate the staging and progression of pancreatic carcinoma. In synergy with MDCT, there has been a notable advent of avant-garde imaging techniques in recent years. These advanced methodologies, including ultrasonography, endoscopic ultrasonography, contrast-enhanced ultrasonography, and magnetic resonance imaging (MRI) conjoined with magnetic resonance cholangiopancreatography (MRCP), have broadened the horizon of tumor characterization, offering unparalleled depth and precision in oncological assessment. Other emerging diagnostic techniques, such as elastography, also hold a lot of potential and promise for the future of pancreatic imaging. Fine needle aspiration (FNA) is a quick, minimally invasive procedure to evaluate lumps using a thin needle to extract tissue for analysis. It is less invasive than surgical biopsies and usually performed as an outpatient with quick recovery. Its accuracy depends on sample quality, and the risks include minimal bleeding or discomfort. Results, guiding further treatment, are typically available within a week. Elastography is a non-invasive medical imaging technique that maps the elastic properties and stiffness of soft tissue. This method, often used in conjunction with ultrasound or MRI, helps differentiate between hard and soft areas in tissue, providing valuable diagnostic information. It is particularly useful for assessing liver fibrosis, thyroid nodules, breast lumps, and musculoskeletal conditions. The technique is painless and involves applying gentle pressure to the area being examined. The resulting images show tissue stiffness, indicating potential abnormalities. Elastography is advantageous for its ability to detect diseases in early stages and monitor treatment effectiveness. The procedure is quick, safe, and requires no special preparation, with results typically available immediately. Results: The assembled and gathered data shows the efficacy of various techniques in discerning the nature and extent of neoplastic lesions within the pancreas. Conclusions: The most common imaging modalities currently used in diagnosing pancreatic neoplasms are multidetector computed tomography (MDCT), endoscopic ultrasound (EUS), and magnetic resonance imaging (MRI), alongside new technologies, such as elastography.

Development of pancreatic diseases during long-term follow-up after acute pancreatitis: a post-hoc analysis of a prospective multicenter cohort. J Gastroenterol Hepatol 2024; 39:674-684. [PMID: 38191176 DOI: 10.1111/jgh.16453] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/08/2023] [Revised: 10/30/2023] [Accepted: 12/11/2023] [Indexed: 01/10/2024]
Abstract
BACKGROUND AND AIM More insight into the incidence of and factors associated with progression following a first episode of acute pancreatitis (AP) would offer opportunities for improvements in disease management and patient counseling. METHODS A long-term post hoc analysis of a prospective cohort of patients with AP (2008-2015) was performed. Primary endpoints were recurrent acute pancreatitis (RAP), chronic pancreatitis (CP), and pancreatic cancer. Cumulative incidence calculations and risk analyses were performed. RESULTS Overall, 1184 patients with a median follow-up of 9 years (IQR: 7-11) were included. RAP and CP occurred in 301 patients (25%) and 72 patients (6%), with the highest incidences observed for alcoholic pancreatitis (40% and 22%). Pancreatic cancer was diagnosed in 14 patients (1%). Predictive factors for RAP were alcoholic and idiopathic pancreatitis (OR 2.70, 95% CI 1.51-4.82 and OR 2.06, 95% CI 1.40-3.02), and no pancreatic interventions (OR 1.82, 95% CI 1.10-3.01). Non-biliary etiology (alcohol: OR 5.24, 95% CI 1.94-14.16, idiopathic: OR 4.57, 95% CI 2.05-10.16, and other: OR 2.97, 95% CI 1.11-7.94), RAP (OR 4.93, 95% CI 2.84-8.58), prior pancreatic interventions (OR 3.10, 95% CI 1.20-8.02), smoking (OR 2.33, 95% CI 1.14-4.78), and male sex (OR 2.06, 95% CI 1.05-4.05) were independently associated with CP. CONCLUSION Disease progression was observed in a quarter of pancreatitis patients. We identified several risk factors that may be helpful to devise personalized strategies with the intention to reduce the impact of disease progression in patients with AP.

Impact of stress hyperglycemia on long-term prognosis in acute pancreatitis without diabetes. Intern Emerg Med 2024; 19:681-688. [PMID: 38372886 DOI: 10.1007/s11739-023-03524-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/08/2023] [Accepted: 12/25/2023] [Indexed: 02/20/2024]
Abstract
Stress hyperglycemia has been confirmed as a strong predictor of poor short-term prognosis in acute pancreatitis. However, whether stress hyperglycemia affects the long-term prognosis of patients with acute pancreatitis is unclear. We aimed to investigate the effect of stress hyperglycemia on the long-term prognosis of non-diabetic patients with acute pancreatitis. This retrospective observational study was conducted on 4055 patients with acute pancreatitis from 1 January 2016 to 31 October 2020. The association between stress hyperglycemia and the prognosis was evaluated using regression modeling. There were 935(71.5%) normoglycemic and 373(28.5%) stress hyperglycemia patients. 46(12.3%) patients with stress hyperglycemia had evidence of diabetes compared with 33(3.5%) patients without stress hyperglycemia (P < 0.001). After multivariate adjustment, patients with stress hyperglycemia were more likely to have evidence of diabetes (OR 2.905, 95% CI 1.688-4.999) compared with normoglycemic. However, stress hyperglycemia is not associated with the recurrence of pancreatitis and progression to chronic pancreatitis. Stress hyperglycemia was independently associated with diabetes secondary to acute pancreatitis. Accordingly, a follow-up diabetes-screening program for AP with stress hyperglycemia is an important part of identifying the disease as soon as possible, delaying islet damage, and improving the prognosis of post-acute pancreatitis diabetes mellitus.

Development of a novel CT-based index for predicting the number of extracorporeal shockwave lithotripsy (ESWL) sessions required for successful fragmentation of obstructing pancreatic duct stones. Pancreatology 2024:S1424-3903(24)00079-6. [PMID: 38584052 DOI: 10.1016/j.pan.2024.03.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/09/2023] [Revised: 03/19/2024] [Accepted: 03/26/2024] [Indexed: 04/09/2024]
Abstract
BACKGROUND & AIM Extracorporeal shock wave lithotripsy (ESWL) is used for the treatment of pancreatic duct stones (PDS) in patients with chronic pancreatitis (CP). We aimed to develop a CT based index to predict the required number of ESWL sessions for technical success. METHODS We retrospectively evaluated patients with PDS secondary to CP who underwent ESWL. Technical success was defined as the complete fragmentation of stones to <3 mm. CT features including PDS size, number, location, and density in Hounsfield units (HU) were noted. We analyzed the relationship between PDS characteristics and the number of ESWL sessions required for technical success. A multiple linear regression model was used to combine size and density into the pancreatic duct stone (PDS) index that was translated into a web-based calculator. RESULTS There were 206 subjects (mean age 38.6 ± 13.7 years, 59.2% male) who underwent ESWL. PDS size showed a moderate correlation with the number of ESWL sessions (r = 0.42, p < 0.01). PDS in the head required a fewer number of sessions in comparison to those in the body (1.4 ± 0.6 vs. 1.6 ± 0.7, p = 0.01). There was a strong correlation between PDS density and the number of ESWL sessions (r = 0.617, p-value <0.01). The PDS index {0.3793 + [0.0009755 x PDS density (HU)] + [0.02549 x PDS size (mm)]} could accurately predict the required number of ESWL sessions with an AUC of 0.872 (p < 0.01). CONCLUSION The PDS index is a useful predictor of the number of ESWL sessions needed for technical success that can help in planning and patient counseling.

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
Chronic pancreatitis results from repeated episodes of pancreatic inflammation and associated fibrosis leading to the loss of functional exocrine and endocrine pancreatic function. The disease is manifested by abdominal pain, deterioration in quality of life, food maldigestion and malabsorption, diabetes, and an increased risk for pancreatic adenocarcinoma. This review summarizes the latest evidence on the diagnosis and management of chronic pancreatitis and its manifestations. In particular, this review discusses advances in understanding of the role of genetic disorders in the mechanisms of the disease and surgical options for patients refractory to medical therapy. Furthermore, clinical trials are under way to develop medical therapeutics.

Abstract
Chronic pancreatitis (CP) is the end-stage of continuous inflammation and fibrosis in the pancreas evolving from acute- to recurrent acute-, early, and, finally, end-stage CP. Currently, prevention is the only way to reduce disease burden. In this setting, early detection is of great importance. Due to the anatomy and risks associated with direct sampling from pancreatic tissue, most of our information on the human pancreas arises from circulating biomarkers thought to be involved in pancreatic pathophysiology or injury. The present review provides the status of circulating biomarkers involved in the development of and progression to CP.

Abstract
OBJECTIVES To investigate the co-existence of hepatic and pancreatic fibrosis using magnetic resonance elastography (MRE) in chronic pancreatitis (CP), including the association between hepatic and pancreatic MRE-derived stiffness and exploration of potential etiological risk factors. MATERIALS AND METHODS Fifty-four CP patients and 35 healthy controls underwent hepatic and pancreatic MRE with measurements of tissue stiffness. Clinical parameters including stage (probable or definite CP), etiology of CP, the presence of diabetes or exocrine insufficiency, and previous history of common bile duct stenosis were assessed. Uni- and multivariate regression models were used to investigate risk factors associated with hepatic fibrosis/stiffness in CP patients. RESULTS Fifteen percent of CP patients and none of the controls had abnormal liver stiffness (>2.5 kPa), p = 0.02. 5.6% of CP patients had liver stiffness indicating F1 fibrosis (>2.93 kPa). However, hepatic stiffness was not higher in patients than in healthy controls (2.20 ± 0.41 vs 2.08 ± 0.21 kPa, p = 0.10). In patients, a positive association was seen between hepatic and pancreatic stiffness (r = 0.270, p = 0.048). In the multivariate analysis (adjusted for age, gender and BMI), liver stiffness was significantly associated with alcoholic etiology of CP (p = 0.029). In contrast, stage of CP, history of common bile duct stenosis, and the presence of diabetes or exocrine insufficiency were not associated with liver stiffness (all p > 0.14). CONCLUSIONS Only a modest co-existence of hepatic and pancreatic fibrosis was observed in CP. However, the positive association between hepatic and pancreatic stiffness indicates some level of common pathophysiology. Especially, alcoholic etiology of CP was related to increased hepatic stiffness.

Abstract
AIMS Retinoids participate in multiple key processes in the human body e.g., vision, cell differentiation and embryonic development. There is growing evidence of the relationship between retinol, its active metabolite- all-trans retinoic acid (ATRA) - and several pancreatic disorders. Although low levels of ATRA in pancreatic ductal adenocarcinoma (PDAC) tissue have been reported, data on serum levels of ATRA in PDAC is still limited. The aim of our work was to determine serum concentrations of retinol and ATRA in patients with PDAC, type-2 diabetes mellitus (T2DM), chronic pancreatitis (CHP) and healthy controls. METHODS High performance liquid chromatography with UV detection (HPLC) was used to measure serum levels of retinol and ATRA in 246 patients with different stages of PDAC, T2DM, CHP and healthy controls. RESULTS We found a significant decrease in the retinol concentration in PDAC (0.44+/-0.18 mg/L) compared to T2DM (0.65+/-0.19 mg/L, P<0.001), CHP (0.60+/-0.18 mg/L, P< 0.001) and healthy controls (0.61+/-0.15 mg/L, P<0.001), significant decrease of ATRA levels in PDAC (1.14+/-0.49 ug/L) compared to T2DM (1.37+/-0.56 ug/L, P<0.001) and healthy controls(1.43+/-0.55 ug/L, P<0.001). Differences between early stages (I+II) of PDAC and non-carcinoma groups were not significant. We describe correlations between retinol, prealbumin and transferrin, and correlation of ATRA and IGFBP-2. CONCLUSION Significant decrease in retinol and ATRA levels in PDAC compared to T2DM, healthy individuals and/or CHP supports existing evidence of the role of retinoids in PDAC. However, neither ATRA nor retinol are suitable for detection of early PDAC. Correlation of ATRA levels and IGFBP-2 provides new information about a possible IGF and retinol relationship.

Abstract
BACKGROUND/OBJECTIVES The most important risk factor for recurrent pancreatitis after an episode of acute alcoholic pancreatitis is continuation of alcohol use. Current guidelines do not recommend any specific treatment strategy regarding alcohol cessation. The PANDA trial investigates whether implementation of a structured alcohol cessation support program prevents pancreatitis recurrence after a first episode of acute alcoholic pancreatitis. METHODS PANDA is a nationwide cluster randomised superiority trial. Participating hospitals are randomised for the investigational management, consisting of a structured alcohol cessation support program, or current practice. Patients with a first episode of acute pancreatitis caused by harmful drinking (AUDIT score >7 and < 16 for men and >6 and < 14 for women) will be included. The primary endpoint is recurrence of acute pancreatitis. Secondary endpoints include cessation or reduction of alcohol use, other alcohol-related diseases, mortality, quality of life, quality-adjusted life years (QALYs) and costs. The follow-up period comprises one year after inclusion. DISCUSSION This is the first multicentre trial with a cluster randomised trial design to investigate whether a structured alcohol cessation support program reduces recurrent acute pancreatitis in patients after a first episode of acute alcoholic pancreatitis, as compared with current practice. TRIAL REGISTRATION Netherlands Trial Registry (NL8852). Prospectively registered.

Abstract
OBJECTIVES Alcohol and nicotine are the two most important risk factors of chronic pancreatitis and they often occur together. It is still unclear how much they influence the severity of the disease and which of the two addictions should be treated with priority. METHODS We performed a single-center, retrospective, cross-sectional study in a mixed medicosurgical cohort of 870 patients diagnosed with chronic pancreatitis (CP). We analyzed the impact of the drinking pattern and abstinence for alcohol and nicotine on the course of the disease. Patients with alcoholic CP were subdivided in I) patients with "life-time drinking history" (LTDH), II) "current drinkers" with current alcohol abuse without signs of LTDH, and III) "former drinkers" who stopped or reduced alcohol intake dramatically. RESULTS Compared to patients with LTDH, "former drinkers" had a lower rate of exocrine insufficiency (29% vs. 59%) and pseudocysts (33% vs. 49%), were more often relapse-free (37% vs. 5%) and had less abdominal pain. There was no correlation detected between the quantity of alcohol consumption and the severity or progression of the disease. Regarding nicotine, 29 pack years are the threshold for developing early stage of CP. Under nicotine abstinence, only slightly more patients were relapse-free (37% vs. 22%). In contrast, the cumulative amount of nicotine consumed correlated with overall disease severity and the development of pseudocysts. The need for surgery was increased with odds ratios of 1.8 for both, alcohol and nicotine abuse. CONCLUSIONS Alcohol cessation in chronic pancreatitis reduces exocrine insufficiency, abdominal pain and local complications. The effect of nicotine cessation is less pronounced in our cohort. However, nicotine abuse represents an important factor for the development of the disease.

[PMID: 37811814 PMCID: PMC10638543 DOI: 10.1093/bjs/znad318] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2023] [Revised: 08/21/2023] [Accepted: 08/30/2023] [Indexed: 10/10/2023]
Abstract
BACKGROUND Cholecystectomy in patients with idiopathic acute pancreatitis (IAP) is controversial. A randomized trial found cholecystectomy to reduce the recurrence rate of IAP but did not include preoperative endoscopic ultrasonography (EUS). As EUS is effective in detecting gallstone disease, cholecystectomy may be indicated only in patients with gallstone disease. This study aimed to determine the diagnostic value of EUS in patients with IAP, and the rate of recurrent pancreatitis in patients in whom EUS could not determine the aetiology (EUS-negative IAP). METHODS This prospective multicentre cohort study included patients with a first episode of IAP who underwent outpatient EUS. The primary outcome was detection of aetiology by EUS. Secondary outcomes included adverse events after EUS, recurrence of pancreatitis, and quality of life during 1-year follow-up. RESULTS After screening 957 consecutive patients with acute pancreatitis from 24 centres, 105 patients with IAP were included and underwent EUS. In 34 patients (32 per cent), EUS detected an aetiology: (micro)lithiasis and biliary sludge (23.8 per cent), chronic pancreatitis (6.7 per cent), and neoplasms (2.9 per cent); 2 of the latter patients underwent pancreatoduodenectomy. During 1-year follow-up, the pancreatitis recurrence rate was 17 per cent (12 of 71) among patients with EUS-negative IAP versus 6 per cent (2 of 34) among those with positive EUS. Recurrent pancreatitis was associated with poorer quality of life. CONCLUSION EUS detected an aetiology in a one-third of patients with a first episode of IAP, requiring mostly cholecystectomy or pancreatoduodenectomy. The role of cholecystectomy in patients with EUS-negative IAP remains uncertain and warrants further study.

Minimally invasive versus open pancreatoduodenectomy for pancreatic and peri-ampullary neoplasm (DIPLOMA-2): study protocol for an international multicenter patient-blinded randomized controlled trial. Trials 2023; 24:665. [PMID: 37828593 PMCID: PMC10571285 DOI: 10.1186/s13063-023-07657-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2023] [Accepted: 09/16/2023] [Indexed: 10/14/2023] Open
Abstract
BACKGROUND Minimally invasive pancreatoduodenectomy (MIPD) aims to reduce the negative impact of surgery as compared to open pancreatoduodenectomy (OPD) and is increasingly becoming part of clinical practice for selected patients worldwide. However, the safety of MIPD remains a topic of debate and the potential shorter time to functional recovery needs to be confirmed. To guide safe implementation of MIPD, large-scale international randomized trials comparing MIPD and OPD in experienced high-volume centers are needed. We hypothesize that MIPD is non-inferior in terms of overall complications, but superior regarding time to functional recovery, as compared to OPD. METHODS/DESIGN The DIPLOMA-2 trial is an international randomized controlled, patient-blinded, non-inferiority trial performed in 14 high-volume pancreatic centers in Europe with a minimum annual volume of 30 MIPD and 30 OPD. A total of 288 patients with an indication for elective pancreatoduodenectomy for pre-malignant and malignant disease, eligible for both open and minimally invasive approach, are randomly allocated for MIPD or OPD in a 2:1 ratio. Centers perform either laparoscopic or robot-assisted MIPD based on their surgical expertise. The primary outcome is the Comprehensive Complication Index (CCI®), measuring all complications graded according to the Clavien-Dindo classification up to 90 days after surgery. The sample size is calculated with the following assumptions: 2.5% one-sided significance level (α), 80% power (1-β), expected difference of the mean CCI® score of 0 points between MIPD and OPD, and a non-inferiority margin of 7.5 points. The main secondary outcome is time to functional recovery, which will be analyzed for superiority. Other secondary outcomes include post-operative 90-day Fitbit™ measured activity, operative outcomes (e.g., blood loss, operative time, conversion to open surgery, surgeon-reported outcomes), oncological findings in case of malignancy (e.g., R0-resection rate, time to adjuvant treatment, survival), postoperative outcomes (e.g., clinically relevant complications), healthcare resource utilization (length of stay, readmissions, intensive care stay), quality of life, and costs. Postoperative follow-up is up to 36 months. DISCUSSION The DIPLOMA-2 trial aims to establish the safety of MIPD as the new standard of care for this selected patient population undergoing pancreatoduodenectomy in high-volume centers, ultimately aiming for superior patient recovery.

Abstract
OBJECTIVE The use and impact of antibiotics and the impact of causative pathogens on clinical outcomes in a large real-world cohort covering the entire clinical spectrum of necrotizing pancreatitis remain unknown. SUMMARY BACKGROUND DATA International guidelines recommend broad-spectrum antibiotics in patients with suspected infected necrotizing pancreatitis. This recommendation is not based on high-level evidence and clinical effects are unknown. MATERIALS AND METHODS This study is a post-hoc analysis of a nationwide prospective cohort of 401 patients with necrotizing pancreatitis in 15 Dutch centers (2010-2019). Across the patient population from the time of admission to 6 months postadmission, multivariable regression analyses were used to analyze (1) microbiological cultures and (2) antibiotic use. RESULTS Antibiotics were started in 321/401 patients (80%) administered at a median of 5 days (P25-P75: 1-13) after admission. The median duration of antibiotics was 27 days (P25-P75: 15-48). In 221/321 patients (69%) infection was not proven by cultures at the time of initiation of antibiotics. Empirical antibiotics for infected necrosis provided insufficient coverage in 64/128 patients (50%) with a pancreatic culture. Prolonged antibiotic therapy was associated with Enterococcus infection (OR 1.08 [95% CI 1.03-1.16], P =0.01). Enterococcus infection was associated with new/persistent organ failure (OR 3.08 [95% CI 1.35-7.29], P <0.01) and mortality (OR 5.78 [95% CI 1.46-38.73], P =0.03). Yeast was found in 30/147 cultures (20%). DISCUSSION In this nationwide study of patients with necrotizing pancreatitis, the vast majority received antibiotics, typically administered early in the disease course and without a proven infection. Empirical antibiotics were inappropriate based on pancreatic cultures in half the patients. Future clinical research and practice must consider antibiotic selective pressure due to prolonged therapy and coverage of Enterococcus and yeast. Improved guidelines on antimicrobial diagnostics and therapy could reduce inappropriate antibiotic use and improve clinical outcomes.

Impact of etiology on disease course in chronic pancreatitis. Pancreatology 2023; 23:582-588. [PMID: 37393150 DOI: 10.1016/j.pan.2023.06.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/22/2023] [Revised: 06/22/2023] [Accepted: 06/26/2023] [Indexed: 07/03/2023]
Abstract
BACKGROUND Complications in chronic pancreatitis (CP) can be grouped in inflammatory (ICC) and fibrotic (FCC) clusters and pancreatic insufficiency cluster (PIC). However, the association between etiological risk factors and the development of complication clusters remains obscure. In this study, the impact of the etiology and disease duration on disease onset and development of complications was investigated. METHODS This cross-sectional study recruited patients with CP from Mannheim/Germany (n = 870), Gieβen/Germany (n = 100) und Donetsk/Ukraine (n = 104). Etiological risk factors, disease stage, age at disease onset, complications, need for hospitalization and surgery were noted. RESULTS In 1074 patients diagnosed with CP, main risk factors were alcohol and nicotine abuse. An earlier onset of the disease was observed upon nicotine abuse (-4.0 years). Alcohol abuse was only associated with an earlier onset of the definite stage of CP. Alcohol abuse was the major risk factor for the development of ICC (p < 0.0001, multiple regression modeling). Abstinence of alcohol reduced ICC, whereas abstinence of nicotine showed no association. PIC correlated with efferent duct abnormalities and the disease duration. In contrast, FCC was mainly dependent on the disease duration (p < 0.0001; t-test). The presence of any complication cluster correlated with the need for surgery (p < 0.01; X2-test). However, only ICC correlated with a prolonged hospital stay (p < 0.05; t-test). CONCLUSIONS ICC is mainly dependent on alcohol abuse. In contrast, FCC and PIC are mainly dependent on the disease duration. The etiology and disease duration can be used as predictors of the course of disease to provide individual treatment and surveillance strategies.

Relationship of Iron Intake, Ferritin, and Hepcidin with the Transverse Relaxation Rate of Water Protons in the Pancreas. Nutrients 2023; 15:3727. [PMID: 37686761 PMCID: PMC10490090 DOI: 10.3390/nu15173727] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2023] [Revised: 08/13/2023] [Accepted: 08/22/2023] [Indexed: 09/10/2023] Open
Abstract
(1) Background: There is a paucity of markers of iron metabolism in health and disease. The aim was to investigate the associations of iron metabolism with pancreas transverse water proton relaxation rate (R2water) in healthy individuals and people after an attack of pancreatitis. (2) Methods: All participants underwent a 3.0 T magnetic resonance imaging of the abdomen on the same scanner. High-speed T2-corrected multi-echo (HISTO) acquisition at single-voxel magnetic resonance spectroscopy and inline processing were used to quantify pancreas R2water. Habitual dietary intake of iron was determined using the EPIC-Norfolk food frequency questionnaire. Circulating levels of ferritin and hepcidin were measured. Generalised additive models were used, adjusting for age, sex, body mass index, and haemoglobin A1c. (3) Results: A total of 139 individuals (47 healthy individuals, 54 individuals after acute pancreatitis, and 38 individuals after chronic pancreatitis) were included. Total dietary intake of iron was significantly associated with pancreas R2water, consistently in healthy individuals (p < 0.001), individuals after acute pancreatitis (p < 0.001), and individuals after chronic pancreatitis (p < 0.001) across all the statistical models. Ferritin was significantly associated with pancreas R2water, consistently in healthy individuals (p < 0.001), individuals after acute pancreatitis (p < 0.001), and individuals after chronic pancreatitis (p = 0.01) across all adjusted models. Hepcidin was significantly associated with pancreas R2water in individuals after acute pancreatitis (p < 0.001) and individuals after chronic pancreatitis (p = 0.04) in the most adjusted model. (4) Conclusions: Pancreas R2water, corrected for T2, is related to iron metabolism in both health and pancreatitis. This non-invasive marker could be used for automated in vivo identification of intra-pancreatic iron deposition.

Intra-pancreatic fat deposition across the pancreatitis spectrum and the influence of gut hormones. Dig Liver Dis 2023; 55:1081-1090. [PMID: 36878840 DOI: 10.1016/j.dld.2023.02.013] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/12/2022] [Revised: 12/13/2022] [Accepted: 02/15/2023] [Indexed: 03/08/2023]
Abstract
BACKGROUND AND AIMS Acute pancreatitis (AP) and chronic pancreatitis (CP) often represent parts of the spectrum of disease. While growing evidence indicates that intra-pancreatic fat deposition (IPFD) plays an important role in the pathogenesis of pancreatitis, no study of living individuals has investigated IPFD in both AP and CP. Further, the associations between IPFD and gut hormones remain to be elucidated. The aims were to investigate the associations of IPFD with AP, CP, and health; and to study whether gut hormones affect these associations. METHODS Magnetic resonance imaging on the same 3.0 Tesla scanner was used to determine IPFD in 201 study participants. These participants were arranged into the health, AP, and CP groups. Gut hormones (ghrelin, glucagon-like peptide-1, gastric inhibitory peptide, peptide YY, and oxyntomodulin) were measured in blood, both after an 8-hour overnight fasting and after ingestion of a standardised mixed meal. A series of linear regression analyses was run, accounting for age, sex, ethnicity, body mass index, glycated haemoglobin, and triglycerides. RESULTS Both the AP group and CP group had significantly higher IPFD in comparison with the health group, consistently across all models (p for trend 0.027 in the most adjusted model). Ghrelin in the fasted state had a significant positive association with IPFD in the AP group (but not the CP or health group), consistently across all models (p = 0.019 in the most adjusted model). None of the studied gut hormones in the postprandial state was significantly associated with IPFD. CONCLUSION Fat deposition in the pancreas is similarly high in individuals with AP and those with CP. The gut-brain axis, and more specifically overexpression of ghrelin, may contribute to increased IPFD in individuals with AP.

Abstract
INTRODUCTION Chronic pancreatitis (CP) has a negative impact on quality of life (QoL). Because CP is a chronic condition, multiple assessments of QoL are required to obtain a thorough understanding of its impact on patients. Such studies are currently lacking. This study aims to gain insight into the course and predictors of QoL in patients with CP using prospective longitudinal data from a large cohort of patients. METHODS Post hoc analysis of consecutive patients with definite CP registered in a prospective database between 2011 and 2019 in the Netherlands. Patient and disease characteristics, nutritional status, pain severity, medication usage, pancreatic function, and pancreatic interventions were assessed from medical records and through standard follow-up questionnaires. The physical and mental component summary scales of the Short-Form 36 were used to assess physical and mental QoL at baseline and during follow-up. The course of both physical and mental QoL and their associated factors were longitudinally assessed by using generalized linear mixed models. RESULTS Overall, 1,165 patients with definite CP were included for this analysis. During 10-year follow-up, generalized linear mixed model analyses revealed improvements in both physical (41.6-45.2, P < 0.001) and mental (45.9-46.6, P = 0.047) QoL. Younger age, current alcohol consumption, employment, no need for dietetic consultation, no steatorrhea, lower Izbicki pain score, and pain coping mechanism were positively associated with physical QoL ( P < 0.05). For mental QoL, a positive correlation was found between employment, nonalcoholic CP, no need for dietetic consultation, no steatorrhea, lower Izbicki pain score, pain coping mechanism, and surgical treatment. No association was observed between disease duration and longitudinal QoL per patient. DISCUSSION This nationwide study provides insight into the dynamics of physical and mental QoL in patients with CP over time. Important and potentially influenceable factors to improve QoL are nutritional status, exocrine pancreatic function, employment status, and patients' coping strategy.

Abstract
Objective Pancreatitis poses a serious medical problem worldwide. This study aims to explore the epidemiological trends of pancreatitis from 1990 to 2019, analyze the association between disease burden and age, period and birth cohort, and subsequently present a forecast of pancreatitis incidence and deaths. Methods Epidemiologic data were gathered from the Global Health Data Exchange query tool. Joinpoint regression model was used to calculate the average annual percentage changes (AAPCs). Age-period-cohort analysis was utilized to estimate the independent effects of age, period and birth cohort. We also predicted the global epidemiological trends to 2044. Results Globally, the incident cases and deaths of pancreatitis increased 1.63-and 1.65-fold from 1990 to 2019, respectively. Joinpoint regression analysis showed that the age-standardized incidence rate (ASIR) and age-standardized death rate (ASDR) decreased over the past three decades. The age effect indicates that older people have higher age-specific incidence and death rates. The period effect on incidence and deaths showed downward trends from 1990 to 2019. The cohort effect demonstrated that incidence and death risk peaked in the earlier birth cohort and were lower in the latest birth cohort. Incident cases and deaths of pancreatitis may significantly increase in the next 25 years. The ASIRs were predicted to slightly increase, while the ASDRs were predicted to decrease. Conclusion Epidemiologic patterns and trends of pancreatitis across age, period and birth cohort may provide novel insight into public health. Limitations of alcohol use and prevention strategies for pancreatitis are necessary to reduce future burden.

S100A8, S100A9 and S100A8/A9 heterodimer as novel cachexigenic factors for pancreatic cancer-induced cachexia. BMC Cancer 2023; 23:513. [PMID: 37280516 DOI: 10.1186/s12885-023-11009-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2023] [Accepted: 05/25/2023] [Indexed: 06/08/2023] Open
Abstract
BACKGROUND Cancer cachexia, occurring in ~ 80% pancreatic cancer (PC) patients overall, is a paraneoplastic syndrome mediated by cancer-induced systemic inflammation and characterized by weight loss and skeletal muscle wasting. Identifying clinically relevant PC-derived pro-inflammatory factors with cachexigenic potential may provide novel insights and therapeutic strategies. METHODS Pro-inflammatory factors with cachexigenic potential in PC were identified by bioinformatic analysis. The abilities of selected candidate factors in inducing skeletal muscle atrophy were investigated. Expression levels of candidate factors in tumors and sera was compared between PC patients with and without cachexia. Associations between serum levels of the candidates and weight loss were assessed in PC patients. RESULTS S100A8, S100A9, and S100A8/A9 were identified and shown to induce C2C12 myotube atrophy. Tumors of PC patients with cachexia had markedly elevated expression of S100A8 (P = 0.003) and S100A9 (P < 0.001). PC patients with cachexia had significantly higher serum levels of S100A8, S100A9 and S100A8/A9. Serum levels of these factors positively correlated with percentage of weight loss [correlation coefficient: S100A8: 0.33 (P < 0.001); S100A9: 0.30 (P < 0.001); S100A8/A9: 0.24 (P = 0.004)] and independently predicted the occurrence of cachexia [adjusted odds ratio (95% confidence interval) per 1ng/ml increase: S100A8 1.11 (1.02-1.21), P = 0.014; S100A9 1.10 (1.04-1.16), P = 0.001; per 1 µg/ml increase: S100A8/A9 1.04 (1.01-1.06), P = 0.009]. CONCLUSIONS Atrophic effects of S100A8, S100A9, and S100A8/A9 indicated them as potential pathogenic factors of PC-induced cachexia. In addition, the correlation with the degree of weight loss and prediction of cachexia in PC patients implicated their potential utility in the diagnosis of PC-induced cachexia.

Abstract
PURPOSE Chronic pancreatitis (CP) leads to diabetes and pancreatic exocrine insufficiency (PEI). PEI may lead to maldigestion and malnutrition, which may cause fat-soluble vitamin deficiency, sarcopenia and abnormal bone density. We aim to study the prevalence of osteoporosis, sarcopenia and vitamin deficiency among CP patients. METHODS Long-term (4-5 years) follow-up was implemented on CP patients. We recorded CP duration, BMI, smoking, alcohol consumption and medication. We determined the serum values for A, D and E vitamins, albumin, creatinine, haemoglobin, calcium and magnesium. Bone density measurement was taken from the proximal femur and lumbar spine. CT/MRI scans were used to measure for psoas muscle area. RESULTS A total of 33 patients (median age 62 [39-81] years, 61% male) were included. None of these patients had earlier diagnosis of osteopathy, and none of them had known vitamin deficiency or were sarcopenic. Nineteen patients (57%) had pancreatic exocrine insufficiency and of these seven patients (37%) had no pancreatic enzyme replacement therapy (PERT) and one (5%) had inadequate enzyme therapy. During the study, osteoporosis was diagnosed in 20% and possible sarcopenia in 48% of patients. PEI and inadequate PERT was associated with low E vitamin levels (75% vs. 0%, p = 0.012), higher risk of osteoporosis (43% vs. 5.6%, p = 0.013) and sarcopenia (80% vs. 36%, p = 0.044). CONCLUSION This study demonstrates that chronic pancreatitis is associated with osteoporosis, sarcopenia and vitamin deficiency. If untreated, pancreatic exocrine insufficiency is associated with increased risk of these outcomes. This highlights the importance of identifying and treating PEI in CP patients.

Abstract
INTRODUCTION Although abdominal pain is the most prevalent and disabling symptom in patients with chronic pancreatitis (CP), there are also patients who have painless CP. PATIENTS AND METHODS We performed a retrospective analysis of patients with a diagnosis of CP. A total of 279 patients with definite CP with completed demographic and clinical data were included in the final analysis. RESULTS There were 75 (26.9%) patients with painless CP. These patients had a significantly higher mean age at diagnosis, 61.7 years, than the 52.5 years of patients with pain (p < 0.001). Painless and painful CP had similar rates of diabetes mellitus (DM) (28.4% vs. 31.6%) and pancreatic exocrine insufficiency (PEI) (50.0% vs. 52.3%). Painless CP had lower rates of alcoholic etiology, 36.0%, than the 52.5% in painful CP (p < 0.05). Patients older than 55 at the time of CP diagnosis were associated with painless CP with an adjusted odds ratio (aOR) of 3.27 [95% confidence interval (CI): 1.62-6.60]. Alcoholic etiologies were not associated with painless CP, aOR of 0.51 (95% CI: 0.25-0.91). CONCLUSION Patients with painless CP had a significantly higher mean age than patients with painful CP and increased aOR for those older than 55 at CP diagnosis. Painless and painful CP patients had similar rates of DM and PEI, confirming the necessity of routine follow up in all patients with CP.

Abstract
OBJECTIVE Economic evaluation of early surgery compared to the endoscopy-first approach in CP. BACKGROUND In patients with painful CP and a dilated main pancreatic duct, early surgery, as compared with an endoscopy-first approach, leads to more pain reduction with fewer interventions. However, it is unknown if early surgery is more cost-effective than the endoscopy-first approach. METHODS The multicenter Dutch ESCAPE trial randomized patients with CP and a dilated main pancreatic duct between early surgery (surgery within 6 weeks) or the endoscopy-first approach in 30 centers (April 2011-September 2016). Healthcare utilization was prospectively recorded up to 18 months after randomization. Unit costs of resources were determined, and cost-effectiveness and cost-utility analyses were performed from societal and healthcare perspectives. Primary outcomes were the costs per unit decrease on the Izbicki pain score and per gained quality-adjusted life-year. RESULTS In total, 88 patients were included in the analysis, with 44 patients randomized to each group. Total costs were lower in the early surgery group but did not reach statistical significance (mean difference €-4,815 (95% bias-corrected and accelerated confidence interval €-13,113 to €3411; P = 0.25). Early surgery had a probability percentage of 88.4% of being more cost-effective than the endoscopy-first approach at a willingness-to-pay threshold of €0 per day per unit decrease on the Izbicki pain score. The probability percentage per additional gained quality-adjusted life-year was 75.7% at a willingness-to-pay threshold of €50,000. CONCLUSION In patients with painful CP and a dilated main pancreatic duct, early surgery was more cost-effective than the endoscopy-first approach.

[PMID: 36968980 PMCID: PMC10038745 DOI: 10.1055/a-2035-8969] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/09/2022] [Accepted: 01/30/2023] [Indexed: 03/26/2023] Open
Abstract
Background and study aims
Pancreatoscopy-guided electrohydraulic lithotripsy (EHL) has proven to be an effective first-line therapy in symptomatic chronic pancreatitis (CP) patients with obstructing pancreatic duct (PD) stones
1
. However, long-term outcomes of endoscopic EHL remain unknown. The aim of the present study was to evaluate the long-term treatment effects of EHL as first-line therapy and to compare with those obtained in a historical cohort of patients who underwent extracorporeal shockwave lithotripsy (ESWL) as primary treatment.
Patients and methods
An observational retrospective single-center long-term follow-up study was performed including 19 consecutive patients who previously underwent endoscopic EHL compared to 18 patients who underwent ESWL followed by endoscopic retrograde pancreatography (ERP). The primary endpoint was long-term treatment success after EHL or ESWL defined as no recurrence of symptomatic intraductal stones confirmed on imaging. Secondary endpoints for the EHL-population included long-term clinical success (i. e., a similar or lower Izbicki Pain Score or reduction in opiate usage as compared to 6-month follow-up), quality of life (QoL), pancreatic function and hospital re-admission rate.
Results
In the EHL group, 37 % of the patients developed recurrent symptomatic PD stones versus 61 % in the ESWL group after a median follow-up of 35.0 and 76.5 months. Of the patients with recurrence, 71 % versus 100 % underwent a reintervention. Median time to recurrence was 12.0 versus 13.0 months. Clinical success sustained in 58 % of the EHL patients. QoL was not significantly different compared with 6-month follow-up and baseline.
Conclusions
Also at long-term follow-up, endoscopic EHL as first-line treatment is moderately effective for symptomatic CP patients with treatment success rates that seems at least equally effective as ESWL.

Pancreatic exocrine insufficiency is a risk factor for kidney stones in patients with chronic pancreatitis. Pancreatology 2023; 23:294-298. [PMID: 36990843 DOI: 10.1016/j.pan.2023.03.006] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/06/2023] [Revised: 03/12/2023] [Accepted: 03/16/2023] [Indexed: 03/31/2023]
Abstract
INTRODUCTION Most patients with chronic pancreatitis (CP) develop pancreatic exocrine insufficiency (PEI) over the course of the disease. PEI may lead to hyperoxaluria and development of urinary oxalate stones. It has been postulated that the patients with CP may be at increased risk of kidney stone formation, but the data is scarce. We aimed to estimate incidence and risk factors for nephrolithiasis in a Swedish cohort of patients with CP. PATIENTS AND METHODS We performed retrospective analysis of an electronical medical database of patients diagnosed with definite CP during 2003-2020. We excluded patients <18 years of age, those with missing relevant data in medical charts, patients with probable CP (according to the M-ANNHEIM classification system) and those in whom kidney stones were diagnosed before CP diagnosis. RESULTS Some 632 patients with definite CP were followed over a median of 5.3 (IQR 2.4-6.9) years. There were 41 (6.5%) patients diagnosed with kidney stones, of whom 33 (80.5%) were symptomatic. Comparing to patients without kidney stones, patients with nephrolithiasis were older, with median age of 65 (IQR 51-72) years, and a male predominance (80% vs 63%). Cumulative incidence of kidney stones was 2.1%, 5.7%, 12.4% and 16.1% at 5, 10, 15, and 20 years after CP diagnosis, respectively. Multivariable cause-specific Cox regression analysis revealed PEI as independent risk factor for nephrolithiasis (adjusted HR 4.95, 95%CI 1.65-14.84; p = 0.004). Another risk factors were increase in BMI (aHR 1.16 95% CI 1.04-1.30; p = 0.001 per unit increment), and a male sex (4.51, 95% CI 1.01-20.3, p = 0.049). CONCLUSION PEI and increase in BMI are risk factors for kidney stone development in patients with CP. Male CP patents are particularly at increased risk of nephrolithiasis. This should be taken into consideration in general clinical approach to raise awareness among patients and medical workers.

Abstract
BACKGROUND Non-invasive modalities for assessing chronic pancreatitis (CP) are needed in clinical practice. PURPOSE To investigate the correlation between magnetic resonance elastography (MRE)-derived stiffness and T1 relaxation times (as proxies of fibrosis) and explore their relationships to gland volume and pancreatic functions in patients with CP and healthy controls (HCs). MATERIAL AND METHODS In 49 patients with CP and 35 HCs, pancreatic stiffness, T1 relaxation times, and gland volume were assessed. Fecal elastase and the presence of diabetes were used to evaluate pancreatic exocrine and endocrine functions. Uni- and multivariable linear regression models were used to analyze correlations between imaging parameters. RESULTS There was a positive correlation between MRE-derived stiffness and T1 relaxation times in patients with CP (R2 = 0.42; P < 0.001) and HCs (R2 = 0.14; P = 0.028). There was no correlation between MRE-derived stiffness and gland volume in patients (R2 = 0.007; P = 0.065) or HCs (R2 = 0.010; P = 0.57). T1 relaxation time was correlated to gland volume (R2 = 0.19; P = 0.002) in patients with CP but not in the HCs (P = 0.056). Severity of pancreatic functional impairment was reflected by increased fibrosis-related parameters in patients without functional impairment, followed by a further increase in fibrosis-related parameters and reduction in gland volume in patients with pancreatic functional impairments. CONCLUSION Pancreatic MRE-derived stiffness and T1 relaxation times might reflect early pathophysiological changes in CP. The dynamic correlation with pancreatic function suggests that these parameters may be useful for the non-invasive and early identification of CP.

Abstract
Malnutrition in patients with chronic pancreatitis is common, but its evaluation is often missed in clinical practice. Pancreatic exocrine insufficiency is the single most important cause of malnutrition; therefore, it needs to be screened for and treated appropriately. Specific diet regimens in patients suffering from chronic pancreatitis are rarely reported in the literature. Patients suffering from chronic pancreatitis have a higher demand for energy but a lower caloric intake secondary to pancreatic exocrine insufficiency, combined with the malabsorption of liposoluble vitamin and micronutrients, which needs be corrected by appropriate dietary counselling. Diabetes is frequently observed in chronic pancreatitis and classified as type 3c, which is characterized by low levels of both serum insulin and glucagon; therefore, there is a tendency towards hypoglycaemia in patients treated with insulin. Diabetes contributes to malnutrition in chronic pancreatitis. Strategies to treat exocrine and endocrine insufficiency are important to achieve better control of the disease.

Single- and multiparameter magnetic resonance imaging for diagnosing and severity grading of chronic pancreatitis. Abdom Radiol (NY) 2023; 48:630-641. [PMID: 36477631 DOI: 10.1007/s00261-022-03760-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2022] [Revised: 11/29/2022] [Accepted: 11/29/2022] [Indexed: 12/13/2022]
Abstract
PURPOSE The study aimed to determine the performance of advanced magnetic resonance imaging (MRI), including a multiparametric MRI-index, for diagnosing and severity grading of chronic pancreatitis (CP) at various functional stages with focus on detection of CP with preserved pancreatic function. METHODS Fifty-four CP patients and 35 healthy controls underwent MRI including assessment of pancreatic volume, main pancreatic duct (MPD) diameter, T1 relaxation time, magnetic resonance elastography (MRE) derived stiffness, and intravoxel incoherent motion (IVIM) diffusion-weighted imaging. Patients were categorized into three subgroups: Preserved pancreatic function (n = 14), partial pancreatic insufficiency (exocrine insufficiency or diabetes, n = 25), and complete pancreatic insufficiency (exocrine insufficiency and diabetes, n = 15). A multiparametric MRI-index was based on ordinal logistic regression analysis. Diagnostic performances of MRI parameters for diagnosing CP at different functional stages were determined using receiver operating characteristic (ROC) analysis. RESULTS All MRI parameters differed across CP subgroups and healthy controls (all P < 0.001), except for IVIM. T1 relaxation time (ROC area under the curve (ROC-AUC) 0.82), MRE (ROC-AUC 0.88), and MRI-index (ROC-AUC 0.86) showed the highest performance for detecting patients with preserved pancreatic function (early CP) vs. healthy controls. For detecting preserved pancreatic function vs. partial insufficiency, pancreatic volume, MRI-index, and T1 relaxation time performed best (all ROC-AUC > 0.75), with the MRI-index tending to outperform MRE (ROC-AUC 0.77 vs. 0.63; P = 0.10). CONCLUSION Quantitative assessments of T1 relaxation time and MRE-derived stiffness seem promising for diagnosing CP at different functional stages and may together with multiparametric MRI-index be used for early identification, staging and monitoring of CP.

Abstract
Chronic pancreatitis is one of the most challenging disorders from the perspective of its early diagnosis and effective treatment. Within the last decade, the diagnosis of early chronic pancreatitis has been firmly introduced into the practice of gastroenterology. The delineation of this form as an initial stage of chronic pancreatitis is based on the need in early and effective treatment that could cease the progression of the disease and reduce the possibility of its complications.
The diagnostic criteria of chronic pancreatitis have been described in details in the literature; however, specifics of the diagnosis in its early stage have been scarcely highlighted. Chronic pancreatitis is commonly diagnosed with a number of imaging techniques (they can show abnormalities in morphology of the pancreas), as well as laboratory tests (showing functional organ deficit). However, morphological and imaging techniques are insufficient for the diagnosis of the early chronic pancreatitis. A new integral strategy towards early diagnosis seems necessary, that would consider not only the morphology, but also potential etiology, risk factors of the disease and its complications in patients with suspected chronic pancreatitis.
The review of the literature presents the definition of the early pancreatitis and discusses the potential of imaging techniques and functional tests in its diagnosis. An adequate strategy for the diagnosis of the early pancreatitis is formulated, based on an individual patient characteristic with suspected early chronic pancreatitis, namely, risk factors, clinical manifestations, imaging results and serological biomarkers.

Abstract
INTRODUCTION In some patients with chronic pancreatitis, the diagnosis of pancreatic cancer can be missed. The objective of the study was to identify clinical and paraclinical data with statistical significance in the differential diagnosis between chronic pancreatitis and pancreatic cancer. MATERIALS AND METHODS We conducted a retrospective, observational study on a cohort of 120 patients hospitalized over 3 years. The patients were equally distributed in two groups: group A, with 60 patients with pancreatic cancer, and group B, with 60 patients with chronic pancreatitis. The statistical analysis was carried out by using the R program. RESULTS The comparative analysis of pancreatic cancer vs. chronic pancreatitis revealed a stronger link between pancreatic cancer, female gender (p = 0.001) and age over 60 years (p < 0.001). Patients with pancreatic cancer had higher serum values of aspartate aminotransferase (p 0.005), alanine aminotransferase (p 0.006), total bilirubin (p < 0.001), direct bilirubin (p < 0.001), alkaline phosphatase (p 0.030), C-reactive protein (p = 0.049) and uric acid (p 0.001), while patients with chronic pancreatitis presented slightly higher values of amylase (p 0.020) and lipase (p 0.029). CONCLUSIONS Female gender, advanced age, elevated aminotransferases, cholestasis markers and uric acid were associated with a higher probability of pancreatic cancer.

Implementation of an evidence-based management algorithm for patients with chronic pancreatitis (COMBO trial): study protocol for a stepped-wedge cluster-randomized controlled trial. Trials 2023; 24:18.

Abstract
BACKGROUND Chronic pancreatitis (CP) is an inflammatory disease that may be complicated by abdominal pain, pancreatic dysfunction, nutritional deficiencies, and diminished bone density. Importantly, it is also associated with a substantially impaired quality of life and reduced life expectancy. This may partly be explained by suboptimal treatment, in particular the long-term management of this chronic condition, despite several national and international guidelines. Standardization of care through a structured implementation of guideline recommendations may improve the level of care and lower the complication rate of these patients. Therefore, the aim of the present study is to evaluate to what extent patient education and standardization of care, through the implementation of an evidence-based integrated management algorithm, improve quality of life and reduce pain severity in patients with CP. METHODS The COMBO trial is a nationwide stepped-wedge cluster-randomized controlled trial. In a stepwise manner, 26 centers, clustered in 6 health regions, cross-over from current practice to care according to an evidence-based integrated management algorithm. During the current practice phase, study participants are recruited and followed longitudinally through questionnaires. Individual patients contribute data to both study periods. Co-primary study endpoints consist of quality of life (assessed by the PANQOLI score) and level of pain (assessed by the Izbicki questionnaire). Secondary outcomes include process measure outcomes, clinical outcomes (e.g., pancreatic function, nutritional status, bone health, interventions, medication use), utilization of healthcare resources, (in) direct costs, and the level of social participation. Standard follow-up is 35 months from the start of the trial. DISCUSSION This is the first stepped-wedge cluster-randomized controlled trial to investigate whether an evidence-based integrated therapeutic approach improves quality of life and pain severity in patients with CP as compared with current practice. TRIAL REGISTRATION ISRCTN, ISRCTN13042622. Registered on 5 September 2020.

Abstract
We aimed to present the incidence and risk factors for pancreatic cancer in a multicenter retrospective cohort of patients with chronic pancreatitis (CP). Patients with ICD-10 codes for CP (K86.0, K86.1) who underwent abdominal CT or MRI between January 2010 and December 2021 in seven academic hospitals were analyzed. After exclusions, we identified 727 patients with definite CP with a median follow-up of 3.6 years (range 1.0‒12.9). During 3290 person-years of observation, pancreatic cancers were diagnosed in 16 patients (2.20%, 0.49% per year) after a median follow-up of 2.4 years (range 1.4‒6.6), with an age- and sex-standardized incidence ratio of 18.1 (95% CI 10.4‒29.5). The underlying CPs in the 16 pancreatic cancers were classified as chronic obstructive pancreatitis (10, 63%), chronic obstructive and calcifying pancreatitis (4, 25%), chronic calcifying pancreatitis (1, 6%), and autoimmune pancreatitis (1, 6%). Factors associated with pancreatic cancer development included age (HR 4.830, p = 0.006), parenchymal calcification (HR 0.213, p = 0.003), pancreatic duct stricture (HR 2.706, p = 0.048), and serum CA 19‒9 level (HR 3.567, p = 0.014). After adjustment, age over 60 years (HR 4.540, p = 0.009) and serum CA 19‒9 levels greater than 100 U/mL (HR 3.528, p = 0.015) were independent risk factors for pancreatic cancer.

Abstract
BACKGROUND Chronic pancreatitis (CP) may cause intermittent or continuous pain and complications requiring invasive interventions. No specific recommendations for surgical interventions have been presented. Our aim was to determine the surgical treatment strategies for the treatment of CP in the Scandinavian and Baltic countries. METHODS This multi-centre cross sectional study included 1327 CP patients from eight centres. The data was gathered from the Scandinavian Baltic Pancreatic Club (SBPC) database. Patients who underwent pancreatic surgery were analysed. The baseline CP population from the eight centres was used as a reference. The information registered included comorbidities, pancreatic function, previous interventions, time and type of surgery and the EORTC-30 quality of life (QOL) questionnaire. RESULTS Overall, 95/1327 (7%) patients underwent pancreatic surgery. Fifty-one (54%) of these underwent pancreatic surgery for chronic pain (PSCP) and formed the final study group. Median follow-up time was two (range 0-8) years after surgery and seven (1-46) years after diagnosis. The most common surgical procedures were pancreatic resection combined with drainage (54%) followed by pancreatic resections (32%) and drainage procedures (14%). Postoperatively, 47% of the patients were pain free with or without pain medication while 16% had chronic pain episodes, this did not differ from the base CP population. In QOL questionnaires, PSCP patients reported the same QOL but worse social functioning and more symptoms compared to the CP population. CONCLUSIONS Pancreatic surgery for CP is rare: surgical procedures were performed on only 7% of the CP patients in the SBPC database. In half of the patients the indication was pain. Most of these patients underwent endoscopic procedures before surgery. Half of the patients reported being pain-free after surgery.

Abstract
We tested the hypothesis that six toxic risk factors from the TIGAR-O classification system are equally important for risk of chronic pancreatitis, at the level of the individual patient and in the general population. 108,438 women and men aged 20-100 years participating in the Copenhagen General Population Study from 2003 to 2015 were included. Associations of smoking, alcohol intake, waist/hip ratio, kidney function, plasma triglycerides, plasma Ca2+, and diseases within the causal pathway with risk of chronic pancreatitis, and corresponding population attributable risks were estimated. Information on chronic pancreatitis was from national Danish health registries. During median 9 years (range: 0-15) of follow-up, 313 individuals had a first diagnosis of chronic pancreatitis; the incidence of chronic pancreatitis per 10,000 person-years were 3.1 overall, 2.8 in women, and 3.5 in men. Of the six toxic risk factors and relative to individuals with low values, individuals in the top 5% had hazard ratios for chronic pancreatitis of 3.1(95% CI 2.1-4.5) for pack-years smoked, 2.5(1.5-4.0) for alcohol intake, and 1.6(1.1-2.6) for plasma triglycerides. Corresponding values versus those without the baseline disease were 12.6 (7.9-20.2) for acute pancreatitis, 1.9 (1.2-2.8) for gallstone disease, and 1.9 (1.3-2.7) for diabetes mellitus. The highest population attributable fractions were for women (1) ever smoking (31%), (2) gallstone disease (5%), and (3) diabetes mellitus (4%), and for men (1) ever smoking (38%), (2) acute pancreatitis (7%)/high alcohol intake (7%), and (3) high plasma triglycerides (5%). Smoking is the most important risk factor for chronic pancreatitis in the general population.

Abstract
PURPOSE The need for incorporation of quantitative imaging biomarkers of pancreatic parenchymal and ductal structures has been highlighted in recent proposals for new scoring systems in chronic pancreatitis (CP). To quantify inter- and intra-observer variability in CT-based measurements of ductal- and gland diameters in CP patients. MATERIALS AND METHODS Prospectively acquired pancreatic CT examinations from 50 CP patients were reviewed by 12 radiologists and four pancreatologists from 10 institutions. Assessment entailed measuring maximum diameter in the axial plane of four structures: (1) pancreatic head (PDhead), (2) pancreatic body (PDbody), (3) main pancreatic duct in the pancreatic head (MPDhead), and (4) body (MPDbody). Agreement was assessed by the 95% limits of agreement with the mean (LOAM), representing how much a single measurement for a specific subject may plausibly deviate from the mean of all measurements on the specific subject. Bland-Altman limits of agreement (LoA) were generated for intra-observer pairs. RESULTS The 16 observers completed 6400 caliper placements comprising a first and second measurement session. The widest inter-observer LOAM was seen with PDhead (± 9.1 mm), followed by PDbody (± 5.1 mm), MPDhead (± 3.2 mm), and MPDbody (± 2.6 mm), whereas the mean intra-observer LoA width was ± 7.3, ± 5.1, ± 3.7, and ± 2.4 mm, respectively. CONCLUSION Substantial intra- and inter-observer variability was observed in pancreatic two-point measurements. This was especially pronounced for parenchymal and duct diameters of the pancreatic head. These findings challenge the implementation of two-point measurements as the foundation for quantitative imaging scoring systems in CP.

Abstract
OBJECTIVES Worldwide prevalence of chronic pancreatitis (CP) has risen in recent years, with data suggesting an increased risk of atherosclerotic cardiovascular disease (ASCVD) in these patients. We assessed the incidence and risk of ASCVD in patients with CP. METHODS We compared the risk of ischemic heart disease, cerebrovascular accident, and peripheral arterial disease between CP and non-CP cohorts after propensity matching of known risk factors of ASCVD using TriNetX, a multi-institutional database. We also evaluated the risk of outcomes of ischemic heart disease including acute coronary syndrome, heart failure, cardiac arrest, and all-cause mortality between CP and non-CP cohorts. RESULTS Chronic pancreatitis cohort was also found to have an increased risk of ischemic heart disease (adjusted odds ratio [aOR], 1.08; 95% confidence interval [CI], 1.03-1.12), cerebrovascular accident (aOR, 1.12; 95% CI, 1.05-1.20), and peripheral arterial disease (aOR, 1.17; 95% CI, 1.1-1.24). Chronic pancreatitis patients with ischemic heart disease were also found to have an increased risk of acute coronary syndrome (aOR, 1.16; 95% CI, 1.04-1.30), cardiac arrest (aOR, 1.24; 95% CI, 1.01-1.53), and mortality (aOR, 1.60; 95% CI, 1.45-1.77). CONCLUSIONS Chronic pancreatitis patients are at a higher risk of ASCVD when compared with the general population, matched for confounding etiological, pharmacological, and comorbid variables.

Abstract
OBJECTIVE Lumen-apposing metal stents (LAMS) are believed to clinically improve endoscopic transluminal drainage of infected necrosis when compared with double-pigtail plastic stents. However, comparative data from prospective studies are very limited. DESIGN Patients with infected necrotising pancreatitis, who underwent an endoscopic step-up approach with LAMS within a multicentre prospective cohort study were compared with the data of 51 patients in the randomised TENSION trial who had been assigned to the endoscopic step-up approach with double-pigtail plastic stents. The clinical study protocol was otherwise identical for both groups. Primary end point was the need for endoscopic transluminal necrosectomy. Secondary end points included mortality, major complications, hospital stay and healthcare costs. RESULTS A total of 53 patients were treated with LAMS in 16 hospitals during 27 months. The need for endoscopic transluminal necrosectomy was 64% (n=34) and was not different from the previous trial using plastic stents (53%, n=27)), also after correction for baseline characteristics (OR 1.21 (95% CI 0.45 to 3.23)). Secondary end points did not differ between groups either, which also included bleeding requiring intervention-5 patients (9%) after LAMS placement vs 11 patients (22%) after placement of plastic stents (relative risk 0.44; 95% CI 0.16 to 1.17). Total healthcare costs were also comparable (mean difference -€6348, bias-corrected and accelerated 95% CI -€26 386 to €10 121). CONCLUSION Our comparison of two patient groups from two multicentre prospective studies with a similar design suggests that LAMS do not reduce the need for endoscopic transluminal necrosectomy when compared with double-pigtail plastic stents in patients with infected necrotising pancreatitis. Also, the rate of bleeding complications was comparable.

Short- and long-term outcomes of a disruption and disconnection of the pancreatic duct in necrotizing pancreatitis: a multicenter cohort study in 896 patients : Disrupted pancreatic duct in acute pancreatitis. Am J Gastroenterol 2022; 118:880-891. [PMID: 36707931 DOI: 10.14309/ajg.0000000000002157] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/02/2022] [Accepted: 12/06/2022] [Indexed: 01/29/2023]
Abstract
OBJECTIVES Necrotizing pancreatitis may result in a disrupted or disconnected pancreatic duct (DPD) with the potential for long lasting negative impact on a patient's clinical outcome. There is a lack of detailed data on the full clinical spectrum of DPD which is critical for the development of better diagnostic and treatment strategies. METHODS We performed a long-term post-hoc analysis of a prospectively collected nationwide cohort of 896 patients with necrotizing pancreatitis (2005-2015). The median follow-up after hospital admission was 75 months (P25-P75:41-151). Clinical outcomes of patients with and without DPD were compared using regression analyses, adjusted for potential confounders. Predictive features for DPD were explored. RESULTS DPD was confirmed in 243 (27%) of the 896 patients and resulted in worse clinical outcomes during both the patient's initial admission and follow-up. During hospital admission, DPD was associated with an increased rate of new-onset intensive care unit admission (adjusted-OR2.52 [95%-CI 1.62-3.93]), new-onset organ failure (adjusted-OR2.26 [95%-CI 1.45-3.55]), infected necrosis (adjusted-OR4.63 [95%-CI 2.87-7.64]) and pancreatic interventions (adjusted-OR7.55 [95%-CI 4.23-13.96]). During long-term follow-up, DPD increased the risk of pancreatic intervention (adjusted-OR9.71 [95%-CI 5.37-18.30], recurrent pancreatitis (adjusted-OR2.08 [95%-CI 1.32-3.29]), chronic pancreatitis (adjusted-OR2.73 [95%-CI 1.47-5.15]) and endocrine pancreatic insufficiency (adjusted-OR1.63 [95%-CI 1.05-2.53]).Central or subtotal pancreatic necrosis on computed tomography (CT), (OR9.49 [95%-CI 6.31-14.29] and a high levels of serum C-reactive protein (CRP) in the first 48 hours after admission (per 10 points increase, OR1.02 [95%-CI 1.00-1.03] were identified as independent predictors for developing DPD. CONCLUSIONS At least one of every four patients with necrotizing pancreatitis suffer from DPD which is associated with detrimental, short and long-term interventions and complications. Central and subtotal pancreatic necrosis and high levels of serum CRP in the first 48 hours are independent predictors for DPD.

Tailored surgery in chronic pancreatitis after implementation of a multidisciplinary team assessment; a prospective observational study. HPB (Oxford) 2022; 24:2157-2166. [PMID: 36272955 DOI: 10.1016/j.hpb.2022.09.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/07/2022] [Revised: 09/15/2022] [Accepted: 09/28/2022] [Indexed: 01/24/2023]
Abstract
INTRODUCTION Optimal management of chronic pancreatitis involves several specialties. Selection of patients for surgery may benefit from evaluation by a multidisciplinary team (MDT), similar to cancer care. The aim of this study was to evaluate outcomes in patients selected for surgery after MDT decision. METHODS A prospective, observational study of consecutive patients operated for pain due to chronic pancreatitis after implementation of a MDT. The main outcome was Quality of life (QoL) assessed by EORTC-QLQ C30 and pain relief in patients followed >3 months. Complications were registered and predictive factors for pain relief analyzed. RESULTS Of 269 patients evaluated by the MDT, 60 (22%) underwent surgery. Postoperative surgical complications occurred in five patients (8.3%) and reoperation within 30 days in two. There was no 90-days mortality. Complete or partial pain relief was achieved in 44 of 50 patients followed >3 months (88%). Preoperative duration of pain predicted lower probability of success. Postoperative improvement in QoL was most prominent for pain, appetite and nausea. CONCLUSIONS After MDT evaluation, one in five patients was selected for surgery. Pain relief was obtained in a majority of patients with improved QoL. A tailored approach through a MDT seems warranted and efficient.

Abstract
OBJECTIVES In patients with chronic pancreatitis, pancreatic duct leakage is associated with a prolonged disease course and serious complications. We aimed to assess the efficacy of this multimodal treatment of pancreatic duct leakage. METHODS In a retrospective design, patients with chronic pancreatitis, an amylase content greater than 200 U/L in either ascites or pleural fluid and treated between 2011 and 2020, were evaluated. The primary end point was treatment success. RESULTS Twenty-seven patients (22 males, median age 60, median American Society of Anesthesiologists score 3) were included.Endoscopic retrograde pancreatography was performed in 23 patients (85%) with transpapillary stenting of the main pancreatic duct in 22 patients (96%). Pancreatic sphincterotomy and dilation of the main pancreatic duct were done in 14 patients (61%) and 17 patients (74%), respectively. Twelve patients (44%) were treated with somatostatin analogs, parenteral nutrition, and were "nil by mouth" for a median of 11 days (range, 4-34 days). Six patients (22%) had extracorporeal shock wave lithotripsy due to pancreatic duct stones. One patient (4%) was referred for surgery. All 23 patients (100%) were treated with success after a median of 21 days (range, 5-80 days). CONCLUSIONS Multimodal treatment of pancreatic duct leakage is effective, with minimal need for surgery.

Abstract
INTRODUCTION Pancreatic duct obstruction is the primary indication for endoscopic and/or surgical therapy in patients with chronic pancreatitis (CP). However, the clinical course of medically managed patients in relation to pancreatic duct obstruction is largely unknown. METHODS This was a retrospective cohort study of medically managed patients with CP. We classified patients based on pancreatic duct obstruction from a stricture or stone using cross-sectional imaging (i.e., large vs small duct CP). We compared prevalence of diabetes and exocrine insufficiency (EPI) between subgroups at inclusion and investigated risk of new-onset diabetes, EPI, and all-cause mortality over a follow-up period of 5 years. Changes in pancreatic morphology were studied in patients who underwent follow-up imaging. RESULTS A total of 198 patients (mean age 58 ± 12 years, 70% male, 60% alcoholic etiology, 38% large duct CP) were evaluated. At inclusion, patients with large vs small duct CP had a higher prevalence of both diabetes (43% vs 24%, P = 0.004) and EPI (47% vs 28%, P = 0.007). There was an increased risk of new-onset EPI in patients with large duct CP (hazard ratio 1.72; 95% confidence interval [1.05-2.80], P = 0.031) and higher rates of pancreatic atrophy ( P < 0.001). No differences between groups were observed for new-onset diabetes and all-cause mortality. Conversion from small to large duct CP or vice versa during follow-up was observed in 14% of patients. DISCUSSION In a medically managed cohort of patients, large duct CP was associated with increased risk of EPI and pancreatic atrophy compared with small duct CP.

Abstract
PURPOSE OF REVIEW The incidence of chronic pancreatitis as a progressive inflammation and fibrosis syndrome is on the rise due to increasing awareness and improved imaging modalities. Numerous classification systems have been suggested in recent years to describe the disease, but only few of them have been used to classify the severity and prognostic significance of the disease. Biomarkers for severity and (early) chronic pancreatitis diagnosis are not yet ready for clinical application. RECENT FINDINGS In using the M-ANNHEIM and Chronic Pancreatitis Prognosis Score (COPPS) classification system, the severity assessment and short- and medium-term disease progression is available. A prospectively validated biomarker for early chronic pancreatitis diagnosis is not yet available, metabolome-based approaches seem to have the greatest potential for clinical translation. SUMMARY Currently, due to the lack of universal definition for the early disease stage of chronic pancreatitis, it is difficult to accurately classify these patient cohorts in existing scoring systems. In principle, setting up a suitable scoring system would allow surveillance and establish a therapy approaches flanked by corresponding biomarker panel development. Therapy management of chronic pancreatitis and monitoring by means of scoring systems (such as the COPPS) would make a decisive contribution to improving patient treatment.

Endoscopic Versus Surgical Step-Up Approach for Infected Necrotizing Pancreatitis (ExTENSION): Long-term Follow-up of a Randomized Trial. Gastroenterology 2022; 163:712-722.e14. [PMID: 35580661 DOI: 10.1053/j.gastro.2022.05.015] [Citation(s) in RCA: 28] [Impact Index Per Article: 14.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/23/2021] [Revised: 05/02/2022] [Accepted: 05/11/2022] [Indexed: 01/02/2023]
Abstract
BACKGROUND & AIMS Previous randomized trials, including the Transluminal Endoscopic Step-Up Approach Versus Minimally Invasive Surgical Step-Up Approach in Patients With Infected Pancreatic Necrosis (TENSION) trial, demonstrated that the endoscopic step-up approach might be preferred over the surgical step-up approach in patients with infected necrotizing pancreatitis based on favorable short-term outcomes. We compared long-term clinical outcomes of both step-up approaches after a period of at least 5 years. METHODS In this long-term follow-up study, we reevaluated all clinical data on 83 patients (of the originally 98 included patients) from the TENSION trial who were still alive after the initial 6-month follow-up. The primary end point, similar to the TENSION trial, was a composite of death and major complications. Secondary end points included individual major complications, pancreaticocutaneous fistula, reinterventions, pancreatic insufficiency, and quality of life. RESULTS After a mean follow-up period of 7 years, the primary end point occurred in 27 patients (53%) in the endoscopy group and in 27 patients (57%) in the surgery group (risk ratio [RR], 0.93; 95% confidence interval [CI], 0.65-1.32; P = .688). Fewer pancreaticocutaneous fistulas were identified in the endoscopy group (8% vs 34%; RR, 0.23; 95% CI, 0.08-0.83). After the initial 6-month follow-up, the endoscopy group needed fewer reinterventions than the surgery group (7% vs 24%; RR, 0.29; 95% CI, 0.09-0.99). Pancreatic insufficiency and quality of life did not differ between groups. CONCLUSIONS At long-term follow-up, the endoscopic step-up approach was not superior to the surgical step-up approach in reducing death or major complications in patients with infected necrotizing pancreatitis. However, patients assigned to the endoscopic approach developed overall fewer pancreaticocutaneous fistulas and needed fewer reinterventions after the initial 6-month follow-up.

Abstract
Studies of therapeutic endoscopic retrograde cholangiopancreatography (ERCP) in geriatric patients have mainly examined patients with biliary diseases, rather than chronic pancreatitis (CP). This study aimed to evaluate the safety and success rate of therapeutic ERCP in geriatric patients with CP. The medical records of patients with CP aged over 65 years (group A) were retrospectively collected in a tertiary hospital from January 2013 to December 2018. Sex-matched CP patients under 65 years (group B) were randomly selected into the control group (matching ratio = 1:2). The success rate and the complication rate of therapeutic ERCP in 2 groups were compared. The risk factors for post-ERCP pancreatitis were investigated by univariate and multivariate analyses. A total of 268 ERCPs were performed in 179 patients of group A and 612 ERCPs in 358 patients of group B. The success rate of ERCP in group A was similar to that of group B (92.16% vs 92.32%; P = .936). The overall incidence of post-ERCP complications was 7.09% (19/268) and 5.72% (35/612) in group A and B, respectively (P = .436). However, geriatric patients had a significantly increased occurrence of moderate to severe complications (2.61% vs 0.16%; P = .002). Female gender (odds ratio [OR] = 3.40; P = .046), pancreas divisum (OR = 7.15; P = .049), dorsal pancreatogram (OR = 7.40; P = .010), and lithotripsy (OR = 0.15; P = .016) were significantly associated with risk of post-ERCP pancreatitis in geriatric patients. Therapeutic ERCP is safe and feasible in elderly patients with CP. However, occurrence of moderate to severe complications after ERCP increased in geriatric patients.
