RÉSUMÉ
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.âe., 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, 37â% of the patients developed recurrent symptomatic PD stones versus 61â% in the ESWL group after a median follow-up of 35.0 and 76.5 months. Of the patients with recurrence, 71â% versus 100â% underwent a reintervention. Median time to recurrence was 12.0 versus 13.0 months. Clinical success sustained in 58â% 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.
RÉSUMÉ
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.

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.

OBJECTIVE: The aim of this study was to explore the incidence, risk factors, clinical course and treatment of perforation and fistula of the gastrointestinal (GI) tract in a large unselected cohort of patients with necrotizing pancreatitis. BACKGROUND: Perforation and fistula of the GI tract may occur in necrotizing pancreatitis. Data from large unselected patient populations on the incidence, risk factors, clinical outcomes, and treatment are lacking. METHODS: We performed a post hoc analysis of a nationwide prospective database of 896 patients with necrotizing pancreatitis. GI tract perforation and fistula were defined as spontaneous or iatrogenic discontinuation of the GI wall. Multivariable logistic regression was used to explore risk factors and to adjust for confounders to explore associations of the GI tract perforation and fistula on the clinical course. RESULTS: A perforation or fistula of the GI tract was identified in 139 (16%) patients, located in the stomach in 23 (14%), duodenum in 56 (35%), jejunum or ileum in 18 (11%), and colon in 64 (40%). Risk factors were high C-reactive protein within 48 hours after admission [odds ratio (OR): 1.19; 95% confidence interval (CI): 1.01-1.39] and early organ failure (OR: 2.76; 95% CI: 1.78-4.29). Prior invasive intervention was a risk factor for developing a perforation or fistula of the lower GI tract (OR: 2.60; 95% CI: 1.04-6.60). While perforation or fistula of the upper GI tract appeared to be protective for persistent intensive care unit-admission (OR: 0.11, 95% CI: 0.02-0.44) and persistent organ failure (OR: 0.15; 95% CI: 0.02-0.58), perforation or fistula of the lower GI tract was associated with a higher rate of new onset organ failure (OR: 2.47; 95% CI: 1.23-4.84). When the stomach or duodenum was affected, treatment was mostly conservative (n=54, 68%). Treatment was mostly surgical when the colon was affected (n=38, 59%). CONCLUSIONS: Perforation and fistula of the GI tract occurred in one out of six patients with necrotizing pancreatitis. Risk factors were high C-reactive protein within 48 hours and early organ failure. Prior intervention was identified as a risk factor for perforation or fistula of the lower GI tract. The clinical course was mostly affected by involvement of the lower GI tract.

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.

BACKGROUND: Surgery is the most effective treatment in patients with painful chronic pancreatitis and a dilated pancreatic duct. Studies reporting the outcomes of selected surgical approach according to the pancreatic head size in these patients are lacking. METHOD: This was a retrospective, observational single-centre study of consecutive patients who underwent either a Frey procedure or extended lateral pancreaticojejunostomy (eLPJ) for pain due to chronic pancreatitis with a dilated main pancreatic duct (5â mm or more) between 2006 and 2017. A Frey procedure was used in patients with pancreatic head enlargement (40â mm or more) and eLPJ (full-length pancreaticojejunostomy, including transection of the gastroduodenal artery) in others. A biliodigestive bypass was added in the case of biliary obstruction. RESULTS: Overall, 140 of 220 patients met the eligibility criteria: 70 underwent a Frey procedure and 70 an eLPJ. Hepaticojejunostomy was added in 17.1 per cent of patients (Frey: 24.3 per cent; eLPJ: 10.0 per cent (P = 0.025)). Major morbidity occurred in 15.0 per cent of patients (Frey: 21.4 per cent; eLPJ: 8.6 per cent (P = 0.033)). After a median 7.8 years of follow-up, the mean (s.d.) decrease in Izbicki pain score was 33 (27) points (34 (28) points after a Frey procedure; 32 (26) points after an eLPJ). Pain relief was reported as 'very much' by 87.5 per cent of patients (Frey: 86.1 per cent; eLPJ: 88.9 per cent) and as 'partial' by 11.1 per cent (Frey: 13.8 per cent; eLPJ: 8.3 per cent). CONCLUSION: Selective-use of either a Frey procedure or eLPJ in patients with symptomatic chronic pancreatitis was-associated with low morbidity and long-term pain relief. Adding a-biliodigestive bypass did not increase morbidity.

OBJECTIVE: The aim of this study was to identify genetic variants associated with early multiple organ failure (MOF) in acute pancreatitis. SUMMARY BACKGROUND DATA: MOF is a life-threatening complication of acute pancreatitis, and risk factors are largely unknown, especially in early persistent MOF. Genetic risk factors are thought to enhance severity in complex diseases such as acute pancreatitis. METHODS: A 2-phase study design was conducted. First, we exome sequenced 9 acute pancreatitis patients with early persistent MOF and 9 case-matched patients with mild edematous pancreatitis (phenotypic extremes) from our initial Dutch cohort of 387 patients. Secondly, 48 candidate variants that were overrepresented in MOF patients and 10 additional variants known from literature were genotyped in a replication cohort of 286 Dutch and German patients. RESULTS: Exome sequencing resulted in 161,696 genetic variants, of which the 38,333 non-synonymous variants were selected for downstream analyses. Of these, 153 variants were overrepresented in patients with multiple-organ failure, as compared with patients with mild acute pancreatitis. In total, 58 candidate variants were genotyped in the joined Dutch and German replication cohort. We found the rs12440118 variant of ZNF106 to be overrepresented in patients with MOF (minor allele frequency 20.4% vs 11.6%, Padj=0.026). Additionally, SLC52A1 rs346821 was found to be overrepresented (minor allele frequency 48.0% vs 42.4%, Padj= 0.003) in early MOF. None of the variants known from literature were associated.Conclusions: This study indicates that SLC52A1, a riboflavin plasma membrane transporter, and ZNF106, a zinc finger protein, may be involved in disease progression toward (early) MOF in acute pancreatitis.

OBJECTIVES: We developed an epidemiological algorithm to classify types of diabetes mellitus (DM) in chronic pancreatitis (CP), and applied it to a nationwide prospective longitudinal cohort of CP patients. METHODS: Patients with definite CP (M-ANNHEIM criteria) were classified as having DM types 1, 2, or 3c, or no DM using an algorithm based on epidemiological characteristics: DM onset in relation to age, CP onset, exocrine insufficiency. Variables associated with development of DM were identified. RESULTS: Of 1130 included patients with CP between 2011 and 2018, 368 patients (33%) had DM at inclusion. Among patients with DM, 11 were classified as having type 1 (3%), 159 as type 2 (43%), and 191 as type 3c (52%). Patients with DM type 3c had longer duration of CP, more severe pain and lower physical quality of life. During longitudinal follow-up of median 47 months, 120 (20%) patients developed DM, of which 99 patients were classified as type 3c. This was independently associated with pancreatic endoscopy and surgery. CONCLUSIONS: The described algorithm based on epidemiological characteristics can help to classify types of DM in patients with CP. Diabetes mellitus type 3c is associated with longer duration of CP and more severe CP sequelae.

OBJECTIVE: Pain in chronic pancreatitis is subdivided in a continuous or intermittent pattern, each thought to represent a different entity, requiring specific treatment. Because evidence is missing, we studied pain patterns in a prospective longitudinal nationwide study. DESIGN: 1131 patients with chronic pancreatitis (fulfilling M-ANNHEIM criteria) were included between 2011 and 2018 in 30 Dutch hospitals. Patients with continuous or intermittent pain were compared for demographics, pain characteristics, quality of life (Short-Form 36), imaging findings, disease duration and treatment. Alternation of pain pattern and associated variables were longitudinally assessed using a multivariable multinomial logistic regression model. RESULTS: At inclusion, 589 patients (52%) had continuous pain, 231 patients (20%) had intermittent pain and 311 patients (28%) had no pain. Patients with continuous pain had more severe pain, used more opioids and neuropathic pain medication, and had a lower quality of life. There were no differences between pain patterns for morphological findings on imaging, disease duration and treatment. During a median follow-up of 47 months, 552 of 905 patients (61%) alternated at least once between pain patterns. All alternations were associated with the Visual Analogue Scale pain intensity score and surgery was only associated with the change from pain to no pain. CONCLUSION: Continuous and intermittent pain patterns in chronic pancreatitis do not seem to be the result of distinctly different pathophysiological entities. The subjectively reported character of pain is not related to imaging findings or disease duration. Pain patterns often change over time and are merely a feature of how severity of pain is experienced.

BACKGROUND/OBJECTIVES: Acute pancreatitis is complicated by local and systemic complications in 20-30% of the patients. Accurate prediction of severity may be important for clinical decision making. Our aim is to identify and compare the accuracy of laboratory biomarkers that predict severity and complications in adult patients. METHODS: Medline, EMBASE, Web of Science and Cochrane Library (1993 to August 2020) were searched for studies with an unselected population of patients with acute pancreatitis, that contains accuracy data for ≥1 laboratory biomarker(s) and/or APACHE-II score for the prediction of a patient outcomes of interest during the first 48 h of admission. The primary outcome is moderate severe or severe acute pancreatitis (MSAP/SAP). Secondary outcomes are severe acute pancreatitis, pancreatic necrosis and organ failure. Risk of bias was assed using QUADAS-2. Biomarkers extracted from ≥3 unique sources, were analyzed using hierarchical summary receiver operating characteristic (HSROC) and bivariate model analysis. RESULTS: In total, 181 studies were included in the qualitative analysis reporting on 29 biomarkers. For the primary outcome at admission, summary sensitivities and specificities were, respectively, 87% (95% CI 69-95%) and 88% (95% CI 80-93%) for IL-6 at a threshold of >50 pg/ml, 72% (95% CI 64-79%) and 76% (95% CI 67-84%) for an APACHE-II score of ≥8, and 53% (95% CI 35-71%) and 82% (95% CI 74-88%) for CRP >150 mg/l. HSROC curve analysis confirmed these results. CONCLUSION: This study indicates superiority of IL-6 for the early prediction of MSAP/SAP and may be used for to guide clinical decision making.

OBJECTIVES: Pancreatic exocrine insufficiency (PEI) is a common complication of chronic pancreatitis. However, little is known about the natural course of PEI and the effect of pancreatic enzyme replacement therapy on symptoms. The aim of this study was to evaluate the natural course and treatment of PEI in a nationwide cohort of patients with chronic pancreatitis. METHODS: Patients with chronic pancreatitis were selected from the multicenter Dutch Chronic Pancreatitis Registry. Patients were classified in 3 groups: definite PEI, potential PEI, and no PEI. Definite PEI and no PEI were compared regarding the course of disease, symptoms, treatment, and quality of life. RESULTS: Nine hundred eighty-seven patients were included from 29 centers, of which 304 patients (31%) had definite PEI; 451 (46%), potentially PEI; and 232 (24%), no PEI. Patients with definite PEI had significantly more malabsorption symptoms, a lower body mass index, and aberrant defecation. Lowered quality of life was not independently associated with PEI. Of the PEI patients using pancreatic enzyme replacement therapy, 47% still reported steatorrhea. CONCLUSIONS: Pancreatic exocrine insufficiency is associated with malabsorption symptoms and a lower body mass index. Some form of pancreatic enzyme replacement therapy is reasonably effective in alleviating malabsorption symptoms, but improvement of treatment is needed.

Importance: For patients with painful chronic pancreatitis, surgical treatment is postponed until medical and endoscopic treatment have failed. Observational studies have suggested that earlier surgery could mitigate disease progression, providing better pain control and preserving pancreatic function. Objective: To determine whether early surgery is more effective than the endoscopy-first approach in terms of clinical outcomes. Design, Setting, and Participants: The ESCAPE trial was an unblinded, multicenter, randomized clinical superiority trial involving 30 Dutch hospitals participating in the Dutch Pancreatitis Study Group. From April 2011 until September 2016, a total of 88 patients with chronic pancreatitis, a dilated main pancreatic duct, and who only recently started using prescribed opioids for severe pain (strong opioids for ≤2 months or weak opioids for ≤6 months) were included. The 18-month follow-up period ended in March 2018. Interventions: There were 44 patients randomized to the early surgery group who underwent pancreatic drainage surgery within 6 weeks after randomization and 44 patients randomized to the endoscopy-first approach group who underwent medical treatment, endoscopy including lithotripsy if needed, and surgery if needed. Main Outcomes and Measures: The primary outcome was pain, measured on the Izbicki pain score and integrated over 18 months (range, 0-100 [increasing score indicates more pain severity]). Secondary outcomes were pain relief at the end of follow-up; number of interventions, complications, hospital admissions; pancreatic function; quality of life (measured on the 36-Item Short Form Health Survey [SF-36]); and mortality. Results: Among 88 patients who were randomized (mean age, 52 years; 21 (24%) women), 85 (97%) completed the trial. During 18 months of follow-up, patients in the early surgery group had a lower Izbicki pain score than patients in the group randomized to receive the endoscopy-first approach group (37 vs 49; between-group difference, -12 points [95% CI, -22 to -2]; P = .02). Complete or partial pain relief at end of follow-up was achieved in 23 of 40 patients (58%) in the early surgery vs 16 of 41 (39%)in the endoscopy-first approach group (P = .10). The total number of interventions was lower in the early surgery group (median, 1 vs 3; P < .001). Treatment complications (27% vs 25%), mortality (0% vs 0%), hospital admissions, pancreatic function, and quality of life were not significantly different between early surgery and the endoscopy-first approach. Conclusions and Relevance: Among patients with chronic pancreatitis, early surgery compared with an endoscopy-first approach resulted in lower pain scores when integrated over 18 months. However, further research is needed to assess persistence of differences over time and to replicate the study findings. Trial Registration: ISRCTN Identifier: ISRCTN45877994.

BACKGROUND: The rationale for total pancreatectomy in painful, treatment refractory, chronic pancreatitis is pain control. Concomitant islet cell autotransplantation can prevent the loss of islet cell function. This study aimed to systematically examine the impact of total pancreatectomy with islet cell autotransplantation on pain and quality of life. METHODS: This meta-analysis was conducted according the Meta-analyses of Observational Studies in Epidemiology guideline. The Cochrane Library, PubMed, and Embase were searched for the following terms (1990 through April 2018): total pancreatectomy and chronic pancreatitis. Studies were included when addressing total pancreatectomy with islet cell autotransplantation for chronic pancreatitis in adults. Studies that reported no data on pain, endocrine function, or quality of life were excluded. Quality was assessed using the Newcastle-Ottawa scale for evaluation of all studies. RESULTS: We included 15 observational studies evaluating 1,255 patients, of whom 28% had had endoscopic and 23% operative therapy. One year after total pancreatectomy with islet cell autotransplantation, the opioid-free rate had improved from between 0% and 15% to 63% (95% CI 46-77), and the insulin-free rate had decreased from between 89.5% and 100% to 30% (95% CI 20-43). An alcoholic etiology was associated with a lesser insulin-free rate after total pancreatectomy with islet cell autotransplantation. Quality of life improved statistically after total pancreatectomy with islet cell autotransplantation. Publication bias was present for both opioid and insulin outcomes. CONCLUSION: In selected patients with painful, treatment refractory, chronic pancreatitis, evidence shows that total pancreatectomy with islet cell autotransplantation is effective for pain control in almost two-thirds of patients, whereas the insulin-free rate is relatively low.

BACKGROUND: Pancreatoduodenectomy may lead to new-onset diabetes mellitus, also known as type 3c diabetes, but the exact risk of this complication is unknown. The aim of this review was to assess the risk of new-onset diabetes mellitus after pancreatoduodenectomy. METHODS: A literature search was performed in PubMed, Embase (Ovid), and the Cochrane Library for English articles published from March 1993 until March 2017 (PROSPERO registry number: CRD42016039784). Studies reporting on the risk of new-onset diabetes mellitus after pancreatoduodenectomy were included. For meta-analysis, studies were pooled using the random-effects model. All studies were appraised according to the Newcastle-Ottawa Scale. RESULTS: After screening 1,523 studies, 22 studies involving 1,121 patients were eligible. The mean weighted overall proportion of new-onset diabetes mellitus after pancreatoduodenectomy was 16% (95% confidence interval, 12%-20%). We found no significant difference in risk of new-onset diabetes mellitus when pancreatoduodenectomy was performed for nonmalignant disease after excluding patients with chronic pancreatitis (19% risk; 95% confidence interval, 7%-43%; 6 studies) or for malignant disease (22% risk; 95% confidence interval, 14%-32%; 11 studies), Pâ¯=â¯.71. Among all patients, 6% (95% confidence interval, 4%-10%) developed insulin-dependent new-onset diabetes mellitus. CONCLUSION: This systematic review identified a clinically relevant risk of new-onset diabetes mellitus after pancreatoduodenectomy of which patients should be informed preoperatively.
RÉSUMÉ
OBJECTIVES: This study aims to compare the M-ANNHEIM, Büchler, and Lüneburg diagnostic tools for chronic pancreatitis (CP). METHODS: A cross-sectional analysis of the development of CP was performed in a prospectively collected multicenter cohort including 669 patients after a first episode of acute pancreatitis. We compared the individual components of the M-ANNHEIM, Büchler, and Lüneburg tools, the agreement between tools, and estimated diagnostic accuracy using Bayesian latent-class analysis. RESULTS: A total of 669 patients with acute pancreatitis followed-up for a median period of 57 (interquartile range, 42-70) months were included. Chronic pancreatitis was diagnosed in 50 patients (7%), 59 patients (9%), and 61 patients (9%) by the M-ANNHEIM, Lüneburg, and Büchler tools, respectively. The overall agreement between these tools was substantial (κ = 0.75). Differences between the tools regarding the following criteria led to significant changes in the total number of diagnoses of CP: abdominal pain, recurrent pancreatitis, moderate to marked ductal lesions, endocrine and exocrine insufficiency, pancreatic calcifications, and pancreatic pseudocysts. The Büchler tool had the highest sensitivity (94%), followed by the M-ANNHEIM (87%), and finally the Lüneburg tool (81%). CONCLUSIONS: Differences between diagnostic tools for CP are mainly attributed to presence of clinical symptoms, endocrine insufficiency, and certain morphological complications.

BACKGROUND: The aim of the study was to evaluate the current opinion and clinical decision-making process of international pancreatologists, and to systematically identify key study questions regarding the diagnosis and treatment of chronic pancreatitis (CP) for future research. METHODS: An online survey, including questions regarding the diagnosis and treatment of CP and several controversial clinical case vignettes, was send by e-mail to members of various international pancreatic associations: IHPBA, APA, EPC, ESGE and DPSG. RESULTS: A total of 288 pancreatologists, 56% surgeons and 44% gastroenterologists, from at least 47 countries, participated in the survey. About half (48%) of the specialists used a classification tool for the diagnosis of CP, including the Mayo Clinic (28%), Mannheim (25%), or Büchler (25%) tools. Overall, CT was the preferred imaging modality for evaluation of an enlarged pancreatic head (59%), pseudocyst (55%), calcifications (75%), and peripancreatic fat infiltration (68%). MRI was preferred for assessment of main pancreatic duct (MPD) abnormalities (60%). Total pancreatectomy with auto-islet transplantation was the preferred treatment in patients with parenchymal calcifications without MPD abnormalities and in patients with refractory pain despite maximal medical, endoscopic, and surgical treatment. In patients with an enlarged pancreatic head, 58% preferred initial surgery (PPPD) versus 42% initial endoscopy. In patients with a dilated MPD and intraductal stones 56% preferred initial endoscopic ± ESWL treatment and 29% preferred initial surgical treatment. CONCLUSION: Worldwide, clinical decision-making in CP is largely based on local expertise, beliefs and disbeliefs. Further development of evidence-based guidelines based on well designed (randomized) studies is strongly encouraged.

BACKGROUND AND AIM: Data on non-surgical treatment of groove pancreatitis (GP) and the risk of cancer are lacking. We aimed to determine the prevalence and predictors of cancer in patients in whom the diagnosis GP was considered, and to evaluate symptom improvement after treatment. STUDY: Patients referred with possible GP (2001-2014) were retrospectively included. An experienced radiologist reassessed imaging. GP patients received questionnaires evaluating their symptoms. RESULTS: From the 38 possible GP patients, 10 had cancer (26%) and 28 GP (74%). Compared with cancer patients, GP patients more frequently had cysts (2/10 vs. 18/28, P = 0.03), less often jaundice (6/10 vs 3/27, P < 0.01), an abrupt caliber change of the CBD (5/10 vs. 2/28, P < 0.01) or suspicious cytology (5/9 vs 2/20, P = 0.02). Of the 28 GP patients, 14 patients were treated conservatively of whom 12 reported symptom improvement after a median follow-up of 45 months (range 7-127 months). All 6 patients treated endoscopically and 7/8 patients treated surgically reported symptom improvement. Surgery, performed because of treatment failure (3/8) or inability to exclude malignancy (5/8), caused mortality in 1/8 patients. CONCLUSIONS: Suspicion of pancreatic cancer should be high in patients presenting with possible GP. Conservative, endoscopic and surgical treatment can all lead to symptom improvement, suggesting a 'step-up approach' to GP once cancer is excluded.

BACKGROUND & AIMS: Patients with a first episode of acute pancreatitis can develop recurrent or chronic pancreatitis (CP). However, little is known about the incidence or risk factors for these events. METHODS: We performed a cross-sectional study of 669 patients with a first episode of acute pancreatitis admitted to 15 Dutch hospitals from December 2003 through March 2007. We collected information on disease course, outpatient visits, and hospital readmissions, as well as results from imaging, laboratory, and histology studies. Standardized follow-up questionnaires were sent to all available patients to collect information on hospitalizations and interventions for pancreatic disease, abdominal pain, steatorrhea, diabetes mellitus, medications, and alcohol and tobacco use. Patients were followed up for a median time period of 57 months. Primary end points were recurrent pancreatitis and CP. Risk factors were evaluated using regression analysis. The cumulative risk was assessed using Kaplan-Meier analysis. RESULTS: Recurrent pancreatitis developed in 117 patients (17%), and CP occurred in 51 patients (7.6%). Recurrent pancreatitis developed in 12% of patients with biliary disease, 24% of patients with alcoholic etiology, and 25% of patients with disease of idiopathic or other etiologies; CP occurred in 3%, 16%, and 10% of these patients, respectively. Etiology, smoking, and necrotizing pancreatitis were independent risk factors for recurrent pancreatitis and CP. Acute Physiology and Chronic Health Evaluation II scores at admission also were associated independently with recurrent pancreatitis. The cumulative risk for recurrent pancreatitis over 5 years was highest among smokers at 40% (compared with 13% for nonsmokers). For alcohol abusers and current smokers, the cumulative risks for CP were similar-approximately 18%. In contrast, the cumulative risk of CP increased to 30% in patients who smoked and abused alcohol. CONCLUSIONS: Based on a retrospective analysis of patients admitted to Dutch hospitals, a first episode of acute pancreatitis leads to recurrent pancreatitis in 17% of patients, and almost 8% of patients progress to CP within 5 years. Progression was associated independently with alcoholic etiology, smoking, and a history of pancreatic necrosis. Smoking is the predominant risk factor for recurrent disease, whereas the combination of alcohol abuse and smoking produces the highest cumulative risk for chronic pancreatitis.

This Review covers the latest developments in the treatment options for chronic pancreatitis. Pain is the most frequent and dominant symptom in patients with chronic pancreatitis, which ranges from severe disabling continuous pain to mild pain attacks and pain-free periods. Conventional treatment strategies and recent changes in the treatment of pain in patients with chronic pancreatitis are outlined. The different treatment options for pain consist of medical therapy, endoscopy or surgery. Their related merits and drawbacks are discussed. Finally, novel insights in the field of genetics and microbiota are summarized, and future perspectives are discussed.
