A steady improvement in modern imaging as well as increasing age in society have led to an increasing number of cystic pancreatic tumours being detected. Pancreatic cysts are a clinically challenging entity because they span a broad biological spectrum and their differentiation is often difficult, especially in small tumours. Therefore, they require a differentiated indication for indication of surgery. To determine recommendations for the surgical indication in cystic tumours of the pancreas, a quality committee for pancreatic diseases of the German Society for General and Visceral Surgery performed a systematic literature search and created this review. Based on the current evidence, signs of malignancy and high-risk criteria (icterus due to cystic pancreatic duct obstruction in the bile duct, enhancing mural nodules ≥ 5 mm or solid components in the cyst or pancreatic duct ≥ 10 mm), as well as symptoms, are a surgical indication, independently of the cyst entity (except pseudocysts). If the entity of the pancreatic cyst is detectable by diagnostic imaging, all main duct IPMN and IPMN of the mixed type, all MCN > 4 cm and all SPN should be resected. SCN and branch-duct IPMN without worrisome features do not constitute an indication for surgery. The indication of operation in branch-duct IPMN with relative risk criteria and MCN < 4 cm is the subject of current discussions and should be individualised. By defining indication recommendations, the present work aims to improve the indication quality in cystic pancreatic tumours. However, the surgical indication should always be individualised, taking into account age, comorbidities and the patient's wishes.

Meta-Analysis
BACKGROUND
Pancreatic pseudocyst (PP) and walled-off necrosis can be managed endoscopically, percutaneously or surgically, but with diverse efficacy.
AIMS & METHODS
A comprehensive literature search was carried out from inception to December 2018, to identify articles which compared at least two of the three kinds of treatment modalities, regarding the mortality, clinical success, recurrence, complications, cost and length of hospitalisation (LOH).
RESULTS
The outcomes of endoscopic (ED) and percutaneous drainage (PD) were comparable in six articles. The clinical success of endoscopic intervention was better considering any types of fluid collections (OR = 3.36; 95% confidence interval (CI) 1.48, 7.63; p = 0.004). ED was preferable regarding recurrence of PP (OR = 0.23; 95% CI 0.08, 0.66; p = 0.006). Fifteen articles compared surgical intervention with ED. Significant difference was found in postoperative LOH (WMD (days) = -4.61; 95%CI -7.89, -1.33; p = 0.006) and total LOH (WMD (days) = -3.67; 95%CI -5.00, -2.34; p < 0.001) which favored endoscopy, but ED had lower rate of clinical success (OR = 0.54; 95% CI 0.35, 0.85; p = 0.007) and higher rate of recurrence (OR = 1.80; 95% CI 1.16, 2.79; p = 0.009) in the treatment of PP. Eleven studies compared surgical and percutaneous intervention. PD resulted in higher rate of recurrence (OR = 4.91; 95% CI 1.82, 13.22; p = 0.002) and lower rate of clinical success (OR = 0.13; 95% CI 0.07, 0.22, p < 0.001).
CONCLUSION
Both endoscopy and surgery are preferable over percutaneous intervention, furthermore endoscopic treatment is associated with shorter hospitalisation than surgery.

Urgent Endoscopic Retrograde Cholangiopancreatography (ERCP) vs. Conventional Approach in Acute Biliary Pancreatitis Without Cholangitis: An Updated Systematic Review and Meta-Analysis.
Gallstone disease is the common cause of acute pancreatitis. The role of early endoscopic retrograde cholangiopancreatography (ERCP) in biliary pancreatitis without cholangitis is not well-established. Thus, this study aims to compare the outcome of early ERCP with conservative management in patients with acute biliary pancreatitis without acute cholangitis. An online search of PubMed, PubMed Central, Embase, Scopus, and Clinicaltrials.gov databases was performed for relevant studies published till December 15, 2020. Statistical analysis was performed using RevMan v 5.4 (The Nordic Cochrane Centre, Cochrane Collaboration, Copenhagen). Odds Ratio (OR) with a 95% confidence interval was used for outcome estimation. Among 2700 studies from the database search, we included four studies in the final analysis. Pooling of data showed no significant reduction in mortality (OR 0.59, 95% CI 0.32 to 1.09; p=0.09); overall complications (OR 0.56, 95% CI 0.30 to 1.01; p=0.05); new-onset organ failure (OR 1.06, 95% CI 0.65 to 1.75; p=0.81); pancreatic necrosis (OR 0.80, 95% CI 0.49 to 1.32; p=0.38); pancreatic pseudo-cyst (OR 0.44, 95% CI 0.16 to 1.24; p=0.12); ICU admission (OR 1.64, 95% CI 0.97 to 2.77; p=0.06); and pneumonia development (OR 0.81, 95% CI 0.40 to 1.65; p=0.56) by urgent ERCP comparing with conventional approach for acute biliary pancreatitis without cholangitis. Henceforth, early ERCP in acute biliary pancreatitis without cholangitis did not reduce mortality, complications, and other adverse outcomes compared to the conservative treatment.

Meta-Analysis
Despite routine supplementation, vitamin D insufficiency is often seen in cystic fibrosis (CF) patients on account of pancreatic insufficiency. Vitamin D is a crucial component of bone health and affects nearly all cells of the immune system. However, clinical benefits or harms associated with supplementation are poorly documented. In this systematic review, we included randomized controlled trials (RCTs) that compared vitamin D supplementation with placebo (i.e. 'non-increased dose') in CF patients. Analysing the 8 included RCTs, the intervention group had significantly higher serum 25-hydroxyvitamin D (se25OHD) levels, but there were no significant differences found in the quantitative synthesis of clinical outcomes, including bone disease-, respiratory status- and immunological status-related outcomes. Based on our current results, while a higher vitamin D dose elevates se25OHD, it does not seem to influence clinical outcomes. Future RCTs should include outcomes of past studies and apply longer follow-up periods to document long-term patient-important outcomes.

Review
Can we better predict the biologic behavior of incidental IPMN? A comprehensive analysis of molecular diagnostics and biomarkers in intraductal papillary mucinous neoplasms of the pancreas.
PURPOSE
Predicting the biologic behavior of intraductal papillary mucinous neoplasm (IPMN) remains challenging. Current guidelines utilize patient symptoms and imaging characteristics to determine appropriate surgical candidates. However, the majority of resected cysts remain low-risk lesions, many of which may be feasible to have under surveillance. We herein characterize the most promising and up-to-date molecular diagnostics in order to identify optimal components of a molecular signature to distinguish levels of IPMN dysplasia.
METHODS
A comprehensive systematic review of pertinent literature, including our own experience, was conducted based on the PRISMA guidelines.
RESULTS
Molecular diagnostics in IPMN patient tissue, duodenal secretions, cyst fluid, saliva, and serum were evaluated and organized into the following categories: oncogenes, tumor suppressor genes, glycoproteins, markers of the immune response, proteomics, DNA/RNA mutations, and next-generation sequencing/microRNA. Specific targets in each of these categories, and in aggregate, were identified by their ability to both characterize a cyst as an IPMN and determine the level of cyst dysplasia.
CONCLUSIONS
Combining molecular signatures with clinical and imaging features in this era of next-generation sequencing and advanced computational analysis will enable enhanced sensitivity and specificity of current models to predict the biologic behavior of IPMN.

Review
BACKGROUND AND AIMS
The use of contrast-harmonic EUS (CH-EUS) in routine clinical practice is increasing rapidly but is not yet standardized. We present the levels of evidence (LEs) found in the literature to put its clinical outcomes in the appropriate perspective.
METHODS
We conducted a systematic review of the available English-language articles. The LEs were stratified according to the Oxford Centre for Evidence-Based Medicine guidelines.
RESULTS
Overall, 210 articles were included and presented according to different pathologic conditions. For pancreatic solid neoplasms, the pooled sensitivity and specificity in the diagnosis of pancreatic carcinoma were very high (LE 1); quantitative analysis and guidance of FNA were reported as investigational research (LE 2-3). For pancreatic cystic lesions, the identification of neoplastic solid components as hyperenhanced lesions represented a promising application of CH-EUS (LE 2). For lymph nodes, CH-EUS increased the diagnostic yield of B-mode EUS for the detection of malignancy (LE 2). For submucosal tumors, CH-EUS seemed useful for differential diagnosis and risk stratification (LE 2-3). For other applications, differential diagnosis of gallbladder and vascular abnormalities by CH-EUS were reported (LE 2-3).
CONCLUSIONS
The LEs of CH-EUS in the literature have evolved from the initial descriptive studies to multicenter and prospective trials, and even meta-analyses. The differential diagnosis between benign and malignant lesions is the main field of application of CH-EUS. With regard to pancreatic solid neoplasms, the concomitant use of both CH-EUS and EUS-FNA may have additive value in increasing the overall accuracy by overcoming the false-negative results associated with each individual technique. Other applications are promising but still investigational.

BACKGROUND
The aim of this systematic review is to assess the role of 18-fluorodeoxyglucose positron emission tomography in the preoperative evaluation of intraductal papillary mucinous neoplasms and cystic lesions of the pancreas.
METHODS
A computerized PubMed search was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to identify studies evaluating positron emission tomography in the preoperative evaluation of pancreatic cystic lesions.
RESULTS
A total of 14 studies evaluated the role of 18-fluorodeoxyglucose positron emission tomography/positron emission tomography-computed tomography, 9 of which evaluated only intraductal papillary mucinous neoplasms and 5 evaluated all pancreatic cystic lesions, including intraductal papillary mucinous neoplasms. Pooled analysis was carried out for studies evaluating intraductal papillary mucinous neoplasms only and studies evaluating all cystic lesions. Imaging with 18-fluorodeoxyblucose positron emission tomography had a positive predictive value, negative predictive value, sensitivity, specificity, and accuracy of 90%, 91%, 85%, 95%, and 91% in identifying malignancy (defined as either invasive and/or high-grade dysplasia) in intraductal papillary mucinous neoplasms and a positive predictive value, negative predictive value, sensitivity, specificity, and accuracy of 85%, 81%, 79%, 86%, and 88% in identifying malignancy in other cystic lesions. Pooled analysis reported the positive predictive value, negative predictive value, sensitivity, specificity, and accuracy of Sendai consensus guidelines (SCG) criteria as 69%, 69%, 68%, 55%, and 58%. The Fukuoka consensus guidelines (FCG) only had sensitivity, specificity, and accuracy reported as 61%, 52%, and 52%, respectively.
CONCLUSION
The 18-fluorodeoxyblucose positron emission tomography had a high degree of accuracy of detecting malignancy in intraductal papillary mucinous neoplasm and cystic lesion of the pancreas. Comparison of the utility of positron emission tomography with the Fukuoka consensus guidelines and the Sendai consensus guidelines suggest that positron emission tomography is superior to present guidelines in detecting malignant intraductal papillary mucinous neoplasm and cystic lesion of the pancreas. Further studies in larger patient cohorts may be required to corroborate these findings and to determine the place of positron emission tomography in the management of intraductal papillary mucinous neoplasm and cystic lesions of the pancreas.

Meta-Analysis
BACKGROUND
Mortality risk stratification is essential in lung transplantation (LTx) to allow listing, prioritization and mitigating strategies. In cystic fibrosis (CF) patients, predictors of post-LTx mortality are not established.
METHODS
For this systematic review and meta-analysis, seven databases were searched until January 3, 2018 to identify predictors of post-LTx mortality in CF. We excluded studies of multi-organ transplantation, re-transplantation and graft survival. For multiple studies assessing the same population during overlapping time-periods, the largest one was analyzed. Risk of bias was assessed with the Newcastle-Ottawa scale (NOS). Pooled hazard ratios were calculated using random-effects models.
RESULTS
Fifty-four studies were included in the systematic review and 11 studies in the meta-analyses (low-to-moderate bias risk, NOS score ≥ 5). Among 10 factors assessed in the meta-analysis, B. cepacia complex (BCC) (N = 1451, unadjusted HR = 2.35, 95%CI:1.80-3.06; I = 20.4% and adjusted HR = 2.49, 95%CI:1.74-3.57; I = 46.2%) and ascending chronological year of LTx (N = 4207, unadjusted HR = 0.98, 95%CI:0.97-0.98, I = 4.8%) were predictors of post-LTx mortality. Male gender (N = 2903, adjusted HR = 1.12, 95%CI:1.0-1.26, I = 0%) and age in adults (N = 3677, unadjusted HR = 0.99, 95%CI:0.97-1.00; I = 64.1% and N = 2605, adjusted HR = 0.98, 95%CI:0.97-0.99; I = 34.3%) had borderline significant associations with post-LTx mortality. P. aeruginosa colonization, forced expiratory volume in one second (FEV), pulmonary hypertension, body mass index (BMI), pancreatic insufficiency and CF-related diabetes (CFRD) were not predictors of mortality.
CONCLUSIONS
BCC was associated with a higher post-LTx mortality whereas FEV, pulmonary hypertension, BMI, CFRD and female gender were not associated with post-LTx mortality. These findings indicate that CF-specific risk estimates of post-LTx mortality should be considered.

Review
BACKGROUND
Despite translational evidences suggesting that cystic fibrosis-related abnormal glucose tolerance (CF-related AGT) may begin early in life and is known to be associated with increased morbidity and mortality, current guidelines recommend screening for AGT only from 10 years of age, thus missing the opportunity for early detection and intervention.
METHODS
A systematic review and meta-analysis (PROSPERO number: CRD42021282516) was conducted on studies that reported data on the prevalence of AGT or its subtypes in CF populations. Pooled proportions, risk, and odds ratios with 95 % confidence intervals (CI) were calculated. One-stage dose-response random-effect meta-analysis was used to assess the effect of age on CF-related diabetes (CFRD).
RESULTS
The quantitative analysis included 457 studies and data from 520,544 patients. Every third child with CF (chwCF) (0.31 [95 % CI 0.25-0.37]) and every second adult with CF (awCF) (0.51 [95 % CI 0.45-0.57]) were affected by AGT. Even in the 5-10 years of age subgroup, the proportion of AGT was 0.42 [95 % CI 0.34-0.51]. The prevalence of prediabetes remained unchanged (impaired glucose tolerance in chwCF:0.14 [95 % CI 0.10-0.18]) vs. awCF:0.19 [95 % CI 0.14-0.25]), whereas the proportion of CFRD increased with age (0-5: 0.005 [95 % CI 0.0001-0.15]; 5-10: 0.05 [95 % CI 0.01-0.27]; 10-18: 0.11 [95 % CI 0.08-0.14]; >18 years of age: 0.27 [95 % CI 0.24-0.30]).
CONCLUSION
CF-related AGT is common under 10 years of age. Our study suggests considering earlier AGT screening, starting from 5 years of age. This highlights the imperative for additional research for guideline adjustments and provides the opportunity for early intervention.

INTRODUCTION
With the increasing use of cross-sectional imaging, the incidence of non-symptomatic pancreatic cystic neoplasms is increasing. Surgical management of pancreatic cystic neoplasms possess significant risks of perioperative morbidity and mortality. Our aim was to evaluate endoscopic ultrasound (EUS)-guided ablation as a non-operative treatment of pancreatic cystic neoplasms.
METHODS
We performed a literature search in MEDLINE, Embase and Scopus. All clinical studies examining the safety and efficacy of EUS-guided pancreatic cyst ablation with radiofrequency, sclerosants, ethanol, chemotherapeutics or a combination hereof were included.
RESULTS
A total of 17 studies were included. We found that EUS-guided pancreatic cyst ablation was feasible with complete resolution in up to 86% of cases after 3-12 months. The modality with the most promising results after 3-12 months was chemoablation with complete resolution rates ranging from 46 to 79% (median 64%). The most appropriate follow-up period was estimated to be 12 months. The risk of serious adverse events including pancreatitis was approximately 16%. Very few cyst recurrences have been documented following complete resolution after cyst ablation.
CONCLUSIONS
EUS-guided cyst ablation of pancreatic cystic lesions seems effective and safe as an alternative to surgical resection in patients who are unfit for surgery or who have low-risk pancreatic cystic neoplasms.
