Abstract
Background and Objectives: The radial echoendoscope is still widely used for the investigation of abnormalities in the gastrointestinal wall and for stone detection in the extrahepatic biliary tree. Due to aging patient population, EUS is frequently performed in fragile and elderly individuals. We aimed to compare the maneuverability and image quality of a new thin radial echoendoscope to the current one. Patients and Methods: This evaluation was conducted at a referral academic EUS center. The new radial echoendoscope has a thinner shaft and distal tube and a shorter bending section compared to the previous one. Patients referred for diagnostic EUS with a radial echoendoscope were enrolled. Indications included pancreaticobiliary disease, esophagogastric abnormalities, and neoplasms and rectal cancer staging. Results: We enrolled 177 patients (122 pancreaticobiliary, 48 esophagogastric, and 7 rectal cases). Overall, the new echoendoscope performed better than the previous model in terms of maneuverability during esophageal intubation and transition from the duodenal bulb to the second portion. On the other hand, pylorus traversing was comparable to the current radial echoendoscope. No loss in image quality was appreciated at predefined stations (esophagus, stomach, and duodenum) compared to the current model. On the other hand, image penetration depth in tissue harmonic mode was significantly improved with the new echoendoscope. Conclusions: A new thinner radial echoendoscope showed improved maneuverability compared to the existing version. Image quality was also improved thanks to increased penetration depth in the tissue harmonic mode. We speculate that this new echoendoscope may allow for safer and faster EUS examination, which may prove useful in an aging patient population.

Abstract
BACKGROUND Current imaging modalities are limited in their ability to distinguish pancreatic cancer (PC) from non-neoplastic pancreatic lesions. The diagnostic use of contrast-enhanced endoscopic ultrasonography (CE-EUS) has increased, and its utility has been reported. Recently, contrast-enhanced harmonic EUS (CH-EUS) was reported to facilitate imaging of parenchymal perfusion and microvessels in pancreatobiliary diseases, leading to a high diagnostic accuracy for PC. The present meta-analysis aims to investigate the usefulness of CH-EUS with enhancement pattern for PC diagnosis. METHODS A systematic meta-analysis of all potentially relevant articles identified in PubMed, the Cochrane library, and Medline was carried out. Fixed-effects or random-effects models were used to investigate pooled sensitivity, specificity, positive likelihood ratio, and negative likelihood ratio with 95% confidence interval (CI). RESULTS The study enrolled 887 patients from nine eligible studies. Pooled estimates of sensitivity and specificity were 93% (95% CI, 0.91-0.95) and 80% (95% CI, 0.75-0.85), respectively. Subgroup analyses were carried out on the main results after excluding two outliers. Area under summary receiver operating characteristics curve was 0.97. No publication bias was found using funnel plots. No significant relationship was found between the diagnostic odds ratios and the characteristics of the studies including continent and contrast agent. CONCLUSIONS This meta-analysis showed that CH-EUS with qualitative analysis of enhancement pattern is useful for the diagnosis of PC, and has high sensitivity and accuracy, regardless of the type of contrast agent used. This modality may provide improved diagnostic accuracy for PC in clinical practice.

Abstract
Direct referral of patients for EUS – instead of preprocedural consultation with the endosonographer – has become standard practice (like for other endoscopic procedures) as it is time- and cost-effective. To ensure appropriate indications and safe examinations, the endosonographer should carefully consider what information is needed before accepting the referral. This includes important clinical data regarding relevant comorbidities, the fitness of the patient to consent and undergo the procedure, and the anticoagulation status. In addition, relevant findings from other imaging methods to clarify the clinical question may be necessary. Appropriate knowledge and management of the patients’ anticoagulation and antiplatelet therapy, antibiotic prophylaxis, and sedation issues can avoid unnecessary delays and unsafe procedures. Insisting on optimal preparation, appropriate indications, and clear clinical referral questions will increase the quality of the outcomes of EUS. In this paper, important practical issues regarding EUS preparations are raised and discussed from different points of view.

Abstract
Background and Objectives: Currently, pancreatic cystic lesions (PCLs) are recognized with increasing frequency and have become a more common finding in clinical practice. EUS is challenging in the diagnosis of PCLs and evidence-based decisions are lacking in its application. This study aimed to develop strong recommendations for the use of EUS in the diagnosis of PCLs, based on the experience of experts in the field. Methods: A survey regarding the practice of EUS in the evaluation of PCLs was drafted by the committee member of the International Society of EUS Task Force (ISEUS-TF). It was disseminated to experts of EUS who were also members of the ISEUS-TF. In some cases, percentage agreement with some statements was calculated; in others, the options with the greatest numbers of responses were summarized. Results: Fifteen questions were extracted and disseminated among 60 experts for the survey. Fifty-three experts completed the survey within the specified time frame. The average volume of EUS cases at the experts' institutions is 988.5 cases per year. Conclusion: Despite the limitations of EUS alone in the morphologic diagnosis of PCLs, the results of the survey indicate that EUS-guided fine-needle aspiration is widely expected to become a more valuable method.

Abstract
PURPOSE Post-surgical upper gastrointestinal anatomy may hamper a complete bilio-pancreatic evaluation with a standard echoendoscope. The aim of this study was to assess the role of catheter probe extraductal ultrasound (EDUS) for the evaluation of the common bile duct (CBD) in patients who are status post-gastric surgery and who are suspected of having choledocholithiasis. METHODS We retrospectively analyzed patients with a prior history of gastric surgery, who underwent EDUS for a suspicion of CBD obstruction. For each patient, technical success, accuracy, and safety were recorded. In case of a positive finding of CBD stones, endoscopic retrograde cholangiopancreatography (ERCP) was performed. In case of other findings or a negative EDUS, computed tomography or magnetic resonance cholangiopancreatography (MRCP) was performed as appropriate. RESULTS EDUS was technically successful in all the 11 patients with a Billroth II gastrectomy, while it failed in all the 5 patients with Roux-en-Y gastric surgery. EDUS accuracy was 100% (3 true-positive and 8 true-negative cases). CBD stones, confirmed and successfully extracted at ERCP, were found in two patients, while in one patient EDUS showed a CBD stenosis that was treated with a plastic stent during ERCP; computed tomography at follow-up was negative for cancer. EDUS was correctly negative in 8 patients, as confirmed by MRCP. CONCLUSIONS EDUS may represent an accurate and safe alternative to standard endoscopic ultrasonography and MRCP for the detection of CBD stones in elderly patients who are status post-Billroth II gastric surgery.

Abstract
BACKGROUND The prevalence of malignancy in patients with small solid pancreatic lesions is low; however, early diagnosis is crucial for successful treatment of these cases. Therefore, a method to reliably distinguish between benign and malignant small solid pancreatic lesions would be highly desirable. We investigated the role of endoscopic ultrasound (EUS) elastography in this setting. METHODS Patients with solid pancreatic lesions ≤ 15 mm in size and a definite diagnosis were included. Lesion stiffness relative to the surrounding pancreatic parenchyma, as qualitatively assessed and documented at the time of EUS elastography, was retrospectively compared with the final diagnosis obtained by fine-needle aspiration/biopsy or surgical resection. RESULTS 218 patients were analyzed. The average size of the lesions was 11 ± 3 mm; 23 % were ductal adenocarcinoma, 52 % neuroendocrine tumors, 8 % metastases, and 17 % other entities; 66 % of the lesions were benign. On elastography, 50 % of lesions were stiffer than the surrounding pancreatic parenchyma (stiff lesions) and 50 % were less stiff or of similar stiffness (soft lesions). High stiffness of the lesion had a sensitivity of 84 % (95 % confidence interval 73 % - 91 %), specificity of 67 % (58 % - 74 %), positive predictive value (PPV) of 56 % (50 % - 62 %), and negative predictive value (NPV) of 89 % (83 % - 93 %) for the diagnosis of malignancy. For the diagnosis of pancreatic ductal adenocarcinoma, the sensitivity, specificity, PPV, and NPV were 96 % (87 % - 100 %), 64 % (56 % - 71 %), 45 % (40 % - 50 %), and 98 % (93 % - 100 %), respectively. CONCLUSIONS In patients with small solid pancreatic lesions, EUS elastography can rule out malignancy with a high level of certainty if the lesion appears soft. A stiff lesion can be either benign or malignant.

Abstract
Transabdominal-US is the first-line imaging modality used to assess the whole liver parenchyma and vascularization; EUS assessment of the liver is incomplete and is not sufficient to rule out the presence of focal liver lesions. On the other hand, due the high diagnostic yield in detecting very small (< 1 cm) lesions, EUS is considered complementary to radiological imaging techniques for the investigation of liver parenchyma. Scarce data are available regarding the investigation of liver parenchyma using both EUS-elastography (EUS-E) and CH-EUS. The aim of this review is to evaluate the clinical role of image enhancement techniques, namely EUS-E and contrast harmonic-EUS (CH-EUS), for the evaluation liver diseases. Despite a potential interest for the application of EUS-E in the assessment of liver diseases, available evidence relegates this technique only to research areas, such as the differential diagnosis between benign and malignant focal liver lesions and the quantification of liver fibrosis in diffuse parenchymal diseases. With the future introduction of EUS shear-wave elastography, interesting data can be obtained for the assessment of liver fibrosis during real-time EUS evaluation. The usefulness of CH-EUS for the evaluation of liver disease is limited by the intrinsic EUS ability to explore only the left lobe and a small part of the right lobe. CH-EUS could be used to increase the diagnostic ability of EUS for the detection and characterization of small lesions and for guiding tissue sampling. Targeting EUS-guided treatments with either EUS-E or CH-EUS might represent potential future applications.

Abstract
Background and Objectives: EUS-guided biliary drainage (EUS-BD) was shown to be useful for malignant biliary obstruction (MBO). However, there is lack of consensus on how EUS-BD should be performed. Methods: This was a worldwide multi-institutional survey among members of the International Society of EUS conducted in February 2018. The survey consisted of 10 questions related to the practice of EUS-BD. Results: Forty-six endoscopists of them completed the survey. The majority of endoscopists felt that EUS-BD could replace percutaneous transhepatic biliary drainage after failure of ERCP. Among all EUS-BD methods, the rendezvous stenting technique should be the First choice. Self-expandable metal stents (SEMSs) were recommended by most endoscopists. For EUS-guided hepaticogastrostomy (HGS), superiority of partially-covered SEMS over fully-covered SEMS was not in agreement. 6-Fr cystotomes were recommended for fistula creation. During the HGS approach, longer SEMS (8 or 10 cm) was recommended. During the choledochoduodenostomy approach, 6-cm SEMS was recommended. During the intrahepatic (IH) approach, the IH segment 3 was recommended. Conclusion: This is the first worldwide survey on the practice of EUS-BD for MBO. There were wide variations in practice, and randomized studies are urgently needed to establish the best approach for the management of this condition.

Abstract
BACKGROUND AND AIM Differential diagnosis of localized gallbladder lesions is challenging. The aim of the present study was to evaluate the utility of contrast-enhanced harmonic endoscopic ultrasonography (CH-EUS) for diagnosis of localized gallbladder lesions. METHODS One hundred and twenty-five patients with localized gallbladder lesions were evaluated by CH-EUS between March 2007 and February 2014. This was a single-center retrospective study. Utilities of fundamental B-mode EUS (FB-EUS) and CH-EUS in the differentiation of gallbladder lesions and sludge plug were initially compared. Thereafter, these two examinations were compared with respect to their accuracy in the diagnosis of malignant lesions. Five reviewers blinded to the clinicopathological results evaluated microcirculation patterns in the vascular and perfusion images. RESULTS In the differentiation between gallbladder lesions and sludge plug, FB-EUS had a sensitivity, specificity, and accuracy of 82%, 100%, and 95%, respectively, whereas CH-EUS had a sensitivity, specificity, and accuracy of 100%, 99%, and 99%, respectively. FB-EUS-based diagnosis of carcinomas based on tumor size and/or shape had a sensitivity, specificity, and accuracy of 61-87%, 71-88%, and 74-86%, respectively. Additional information regarding irregular vessel patterns in the vascular image and/or heterogeneous enhancement in the perfusion image on CH-EUS increased the sensitivity, specificity, and accuracy for the diagnosis of carcinomas to 90%, 98%, and 96%, respectively. There was a significant difference between FB-EUS and CH-EUS in terms of carcinoma diagnosis. CONCLUSION CH-EUS was useful for the evaluation of localized gallbladder lesions.

Abstract
BACKGROUND Endoscopic ultrasound (EUS) has been used in the clinical arena for almost 35 years and it is now well-integrated in everyday hospital practice. METHOD We conducted a systematic review of the available English-language articles. OBJECTIVE The purpose of this review is to summarize the relevant applications of operative EUS. RESULTS More than 5000 scientific papers published in the literature have demonstrated its high accuracy for the diagnosis and staging of a variety of benign and malignant conditions. The main indications of operative EUS, both diagnostic and therapeutic, are related to its ability to combine ultrasound imaging and safe and effective needle insertion into lesions originating from the gut wall and from organs nearby. In addition, technologic advancements of echoendoscopes with a therapeutic working-channel have allowed to perform several EUS-guided interventions, i.e. celiac plexus neurolysis, drainage of fluid collections, drainage of dilated biliary and pancreatic ducts, and vascular interventions.

METHODS Between June 2008 and May 2015, 157 consecutive patients with submucosal lesions of the upper gastrointestinal tract were evaluated by CH-EUS. This was a single-center retrospective analysis of prospectively collected data in a registry. The data from 73 patients who later underwent surgical resection were analyzed in this study. Surgical specimens served as the final diagnoses. The two CH-EUS variables of blood flow (hyper-enhancement vs hypo-enhancement) and homogeneity of enhancement pattern were evaluated. RESULTS The final diagnoses were 58 gastrointestinal stromal tumors (GISTs) and 15 benign SMTs (two lipomas, five leiomyomas, five schwannomas, two glomus tumors, and one ectopic pancreas). On CH-EUS, 49 of 58 (84.5%) GISTs presented with hyper-enhancement, whereas 4 of 15 (26.7%) benign SMTs showed hyper-enhancement; 21 of 58 (36.2%) GISTs showed inhomogeneous contrast enhancement, while only 2 of 15 (13.3%) benign SMTs demonstrated inhomogeneous contrast enhancement. If hyper-enhancement was considered to indicate GISTs, the sensitivity, specificity, and accuracy were 84.5%, 73.3%, and 82.2%, respectively. If inhomogeneous enhancement was considered to indicate GISTs, the sensitivity, specificity, and accuracy were 36.2%, 86.7%, and 46.6%, respectively. In lesions of less than 2 cm, hyper-enhancement was a more sensitive indicator of GISTs than inhomogeneous enhancement. CONCLUSIONS Hyper-enhancement and inhomogeneous enhancement were found to be a characteristic of GISTs. CH-EUS was useful for discrimination of benign SMTs from GISTs.

Abstract
OBJECTIVE The aim of this study was to analyze the outcomes of a long-term intraductal papillary mucinous neoplasm (IPMN) registry and evaluate new guidelines. METHODS A prospectively maintained IPMN registry involving 6 centers in Europe and the United States was used to collect the data. Patients with more than 1-year follow-up and no malignancy diagnosed within the first 3 months of surveillance were included. RESULTS From 1999 to 2014, 620 patients were included. The median follow-up time was 3 years. Thirty-seven (6%) patients developed malignancy with a median time from IPMN diagnosis to malignancy of 10.3 months. The 1-, 5-, and 10-year actuarial rates of disease-free survival were 97%, 93%, and 92% respectively. Four hundred thirty-one patients met criteria for low-risk branch duct IPMN consisting of cyst size less than 3 cm, with no solid component or main duct dilation. Eight malignancies were diagnosed in this subgroup, all of them within the first 5 years. From this subcohort, 112 patients had a follow-up time of more than 5 years, and no malignancy was diagnosed. CONCLUSIONS In IPMN lesions with low-risk features at baseline, the risk of progression to malignancy after the first 5 years of follow-up was minimal. Furthermore, the main cyst characteristics remained unchanged during their surveillance.

Abstract
BACKGROUND Percutaneous endoscopic gastrostomy is the preferred option for providing enteral nutrition, allowing for an improvement in survival and quality of life. AIM To evaluate risk factors for early and delayed mortality after gastrostomy placement. METHODS A single-center retrospective analysis of a prospectively-collected database including all patients undergoing gastrostomy placement for enteral nutrition was performed. Two operators performed all the procedures according to the most recent guidelines. RESULTS Analysis included data on 438 patients [178 male; 80.5 (72-86) year-old]. Indications for PEG were stroke (34.0%), dementia (31.3%), neurodegenerative disorders (18.5%), coma (9.1%) and cancer (7.1%). No periprocedural adverse events was observed. Mean survival was 14.6±3.4months; 1-month and 3-month mortality rates were 4.0% and 8.1%, respectively. Severe hypernatremia (≥150mmol/L) was independently related to 1-month mortality (odds ratio 25.4; P<0.0001), while C-reactive protein level>4.3mg/dL was independently related to 3-month mortality (odds ratio 5.3; P=0.003). Kaplan-Meier and Cox-regression analysis identified male gender (hazard ratio 2.32; P=0.0002), severe hypernatremia (hazard ratio 4.3; P<0.0001), C-reactive protein>4.3mg/dL (hazard ratio 3.5; P=0.0014), leukocytosis (hazard ratio 1.97; P=0.0036) and presence of underlying malignancy (hazard ratio 2.4; P=0.0013) as independent risk factors for long-term mortality. DISCUSSION Presence of severe hypernatremia and increased C-reactive protein levels were strongly correlated with early and delayed mortality in our population. Studies are necessary to understand whether correcting underlying dehydration and inflammation further improves patients' outcomes.

Abstract
Objectives: The objective of guideline was to provide clear and relevant consensus statements to form a practical guideline for clinicians on the indications, optimal technique, safety and efficacy of endoscopic ultrasound guided celiac plexus neurolysis (EUS-CPN). Methods: Six important clinical questions were determined regarding EUS-CPN. Following a detailed literature review, 6 statements were proposed attempting to answer those questions. A group of expert endosonographers convened in Chicago, United States (May 2016), where the statements were presented and feedback provided. Subsequently a consensus group of 35 expert endosonographers voted based on their individual level of agreement. A strong recommendation required 80% voter agreement. The modified GRADE (Grading of Recommendations Assessment, Development, and Evaluation) criteria were used to rate the strength of recommendations and the quality of evidence. Results: Eighty percent agreement was reached on 5 of 6 consensus statements, 79.4% agreement was reached on the remaining one. Conclusions: EUS-CPN is efficacious, should be integrated into the management of pancreas cancer pain, and can be considered early at the time of diagnosis of inoperable disease. Techniques may still vary based on operator experience. Serious complications exist, but are rare.

Abstract
There is a lack of consensus on how endoscopic ultrasound (EUS)-guided pseudocyst drainage and endoscopic necrosectomy should be performed. This survey was carried out amongst members of the EUS Journal Editorial Board to describe their practices in performing this procedure. This was a worldwide multi-institutional survey amongst members of the EUS Journal Editorial Board in May 2017. The responses to a 22-question survey with respect to the practice of EUS-guided pseudocyst drainage and endoscopic necrosectomy were obtained. Twenty-two endoscopists responded to the questionnaire as follows: 72.7% (16/22) were of the opinion that lumen-apposing metal stents (LAMS) should be the standard of care for the creation of an endoscopic cystenterostomy in patients with pancreatic walled-off necrosis (WON); 95.5% (21/22) recommended large diameter (d=15 mm) LAMS for drainage in patients with WON; 54.5% (12/22) would not dilate LAMS after placement into the WOPN; 86.4% (19/22) would not perform endoscopic necrosectomy during the same procedure as the creation of the cystenterostomy; 45.5% (10/22) recommend that agents, such as diluted hydrogen peroxide, should be used to lavage the peri-pancreatic fluid collection (PFC) cavity in patients with WON; and 45.5% (10/22) considered a naso-cystic or other tube to be necessary for lavage of WON after initial drainage. The mean optimal interval recommended for endoscopic necrosectomy procedures after EUS-guided drainage was 6.23 days. The mean optimal interval recommended for repeat imaging in patients undergoing endoscopic necrosectomy was 12.32 days. The mean time recommended for LAMS removal was 4.59 weeks. This is the first worldwide survey on the practice of EUS-guided pseudocyst drainage and endoscopic necrosectomy. There were wide variations in practice and randomized studies are urgently needed to establish the best approach for management of this condition. There is also a pressing need to establish a best practice consensus.

Abstract
Incidental pancreatic cysts (PCs) are frequently encountered in the general population often in asymptomatic patients who undergo imaging tests to investigate unrelated conditions. The detection of a PC poses a significant clinical dilemma, as the differential diagnosis is quite broad ranging from benign to malignant conditions. Endoscopic ultrasound (EUS) with fine-needle aspiration (FNA) has been reported to be an accurate tool in the differential diagnosis; however, its sensitivity is suboptimal and false negative results do occur. Contrast harmonic EUS (CH-EUS) was demonstrated to be a useful tool to investigate pancreatic solid lesions to differentiate between benign and malignant ones. In the setting of PCs, CH-EUS could help identify areas of malignant growth inside the cystic cavities. Several studies have reported promising results showing malignant areas in PCs as hyperenhanced lesions. Confirmation of malignancy can then be obtained by FNA, which should be precisely targeted according to the findings of the contrast harmonic study.
