Abstract
Endoscopic ultrasound-guided fine-needle biopsy (EUS-FNB) is an excellent investigation to diagnose pancreatic lesions and has shown high accuracy for its use in pathologic diagnosis. Recently, macroscopic on-site evaluation (MOSE) performed by an endoscopist was introduced as an alternative to rapid on-site cytologic evaluation to increase the diagnostic yield of EUS-FNB. The MOSE of the biopsy can estimate the adequacy of the sample directly by the macroscopic evaluation of the core tissue obtained from EUS-FNB. Isolated pancreatic tuberculosis is extremely rare and difficult to diagnose because of its non-specific signs and symptoms. Therefore, this challenging diagnosis is based on endoscopy, imaging, and the bacteriological and histological examination of tissue biopsies. This uncommon presentation of tuberculosis can be revealed as pancreatic mass mimicking cancer. EUS-FNB can be very useful in providing a valuable histopathological diagnosis. A calcified lesion with a cheesy core in MOSE must be suggestive of tuberculosis, leading to the request of the GeneXpert, which can detect Mycobacterium tuberculosis deoxyribonucleic acid and resistance to rifampicin. A decent diagnostic strategy is crucial to prevent unnecessary surgical resection and to supply conservative management with antitubercular therapy.

Abstract
Pancreaticobiliary malignancies arise from different areas within the pancreas and biliary tree. Endoscopic ultrasound (EUS) is a well-recognized diagnostic and therapeutic modality in the treatment of pancreaticobiliary diseases, and more specifically, pancreaticobiliary malignancies. Traditionally used for diagnostic purposes, EUS plays a critical role in tissue sampling and cancer staging. The emergence of the new field of interventional EUS has allowed EUS to also play a critical role in therapeutic management. Novel interventional EUS procedures such as EUS-guided gastrojejunostomy (EUS-GE), EUS-guided biliary drainage (EUS-BD), and EUS-guided gallbladder drainage (EUS-GLB) can be utilized to treat complications of pancreaticobiliary malignancies such as gastric outlet obstruction, obstructive jaundice, and cholecystitis. In addition, interventional EUS procedures can be utilized for the palliation of unresectable malignancies both for source control with EUS-radiofrequency ablation (EUS-RFA) and for the treatment of abdominal pain refractory to opioid medications with EUS-guided celiac axis neurolysis. However, patient selection remains a critical component in both diagnostic and therapeutic interventions and must be tailored to individual patient wishes, disease pathology, and overall prognosis.

Abstract
CONTEXT Pancreatic masses are routinely encountered on imaging and often present as a diagnostic dilemma. These masses range from benign inflammatory masses, requiring no intervention to malignant masses, which carry grave prognosis and hence require aggressive management. AIMS Compare the diagnostic accuracy of 256 multislice CT and endoscopic ultrasound (EUS) in characterization and assessment of resectability of pancreatic masses and compare the multidetector computed tomography (MDCT) and EUS findings with histopathological findings. SETTINGS AND DESIGN Prospective study. SUBJECTS AND METHODS 36 patients with pancreatic masses were included who underwent dual phase CT using pancreatic protocol and EUS using 5-13 MHz transducer. Fine needle aspiration cytology (FNAC) was done wherever feasible. Parameters regarding tumor size, location, imaging morphology, and vessel involvement were recorded. Findings were compared with histopathological/operative diagnosis/clinical follow-up. STATISTICAL ANALYSIS USED Descriptive statistics with percentages and proportions and Chi-square test. RESULTS Multidetector computed tomography (MDCT) and EUS established diagnosis consistent with tissue diagnosis in 30 (83%) and 22 (61%) patients, respectively. However, the best results were obtained with the combined use of MDCT and EUS. The number of patients categorized as inconclusive by MDCT were lower compared to EUS. Assessing resectability for pancreatic adenocarcinoma, MDCT showed specificity and positive predictive value (PPV) of 100% compared to EUS, which had specificity and PPV of 75% and 92.3%, respectively. MDCT is the first-line imaging modality in detection, characterization of pancreatic masses, and assessment of resectability in malignant neoplasms. EUS is beneficial in the detection of masses <2 cm in size causing pancreatic contour deformity on CT, for guiding FNAC. MDCT and EUS with EUS-guided FNA are complementary not competitive tools in preoperative imaging of pancreatic masses.

Abstract
Background and study aims Carbon dioxide (CO 2 ) is being increasingly used for insufflation during endoscopy for safety and better tolerance. The role of CO 2 during endoscopic ultrasonography (EUS) has not been studied yet. Our main aim was to compare the effects of CO 2 vs. air insufflation on abdominal discomfort in patients undergoing EUS. Our secondary outcomes were to ascertain the effects of CO 2 insufflation on image quality/visual artifacts and on the amount of sedation. Patients and methods This was a prospective, controlled, single-blind, observational study. Abdominal discomfort was assessed before diagnostic EUS, and 1 and 3 hours post-procedure and recorded as a visual analogue scale. Image quality was also recorded as a 4-point scale from optimal to poor at four different scanning sites (esophagus, stomach, duodenal bulb and second portion). Results A total of 198 patients were enrolled. We observed that CO 2 resulted in less abdominal discomfort than air insufflation that was statistically significant at 3 hours ( P = 0.048) but not at 1 hour after EUS ( P = 0.112), probably due to the ongoing effects of sedation at the latter stage. On the other hand, no differences were found in the dose of sedation administered in the two groups. Image quality was significantly better in the CO 2 group compared to the air group at all four different scanning sites ( P < 0.01). Similarly, CO 2 correlated with less visual artifacts and need of suction ( P < 0.01). Conclusions Similarly to previous findings with other endoscopic procedures, EUS was associated with improved scores for abdominal discomfort with CO 2 rather than air insufflation. Moreover, overall EUS image quality was improved using CO 2 insufflation. Future studies are warranted to ascertain whether CO 2 insufflation should be regarded as the standard of care for diagnostic EUS.

Abstract
BACKGROUND & AIMS Despite the widespread use of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) to sample pancreatic lesions and the standardization of pancreaticobiliary cytopathologic nomenclature, there are few data on inter-observer agreement among cytopathologists evaluating pancreatic cytologic specimens obtained by EUS-FNA. We developed a scoring system to assess agreement among cytopathologists in overall diagnosis and quantitative and qualitative parameters, and evaluated factors associated with agreement. METHODS We performed a prospective study to validate results from our pilot study that demonstrated moderate to substantial inter-observer agreement among cytopathologists for the final cytologic diagnosis. In the first phase, 3 cytopathologists refined criteria for assessment of quantity and quality measures. During phase 2, EUS-FNA specimens of solid pancreatic lesions from 46 patients were evaluated by 11 cytopathologists at 5 tertiary care centers using a standardized scoring tool. Individual quantitative and qualitative measures were scored and an overall cytologic diagnosis was determined. Clinical and EUS parameters were assessed as predictors of unanimous agreement. Inter-observer agreement (IOA) was calculated using multi-rater kappa (κ) statistics and a logistic regression model was created to identify factors associated with unanimous agreement. RESULTS The IOA for final diagnoses, based on cytologic analysis, was moderate (κ = 0.56; 95% CI, 0.43-0.70). Kappa values did not increase when categories of suspicious for malignancy, malignant, and neoplasm were combined. IOA was slight to moderate for individual quantitative (κ = 0.007; 95% CI, -0.03 to -0.04) and qualitative parameters (κ = 0.5; 95% CI, 0.47-0.53). Jaundice was the only factor associated with agreement among all cytopathologists on multivariate analysis (odds ratio for unanimous agreement, 5.3; 95% CI, 1.1-26.89). CONCLUSIONS There is a suboptimal level of agreement among cytopathologists in the diagnosis of malignancy based on analysis of EUS-FNA specimens obtained from solid pancreatic masses. Strategies are needed to refine the cytologic criteria for diagnosis of malignancy and enhance tissue acquisition techniques to improve diagnostic reproducibility among cytopathologists.

Abstract
OBJECTIVES The development of an effective screening method for pancreatic ductal adenocarcinoma (PDAC) is of paramount importance. This study assessed the diagnostic utility in pancreatic diseases of duodenal markers during upper gastrointestinal endoscopy (GIE) or endoscopic ultrasonography. METHODS This study prospectively enrolled 299 consecutive participants, including 94 patients with PDACs, 144 patients with other pancreatic diseases, and 61 normal individuals as control subjects. All subjects underwent upper GIE or endoscopic ultrasonography either at Kyushu University Hospital (Fukuoka, Japan) or the Mayo Clinic (Jacksonville, Fla) from October 2011 to July 2014. Duodenal fluid (DF) was collected without secretin stimulation and of carcinoembryonic antigen and S100 calcium-binding protein P (S100P) concentrations were measured. RESULTS Concentrations of S100P in DF were significantly higher in patients with PDAC and chronic pancreatitis than in control subjects (P < 0.01). A logistic regression model that included age found that the sensitivity and specificity of S100P concentration in diagnosing stages 0/IA/IB/IIA PDAC were 85% and 77%, respectively, with an area under the receiver operating characteristic curve of 0.82. Carcinoembryonic antigen concentrations in DF of patients with pancreatic disease did not differ significantly from control subjects. CONCLUSIONS Analysis of S100P concentration in DF, in combination with routine screening upper GIE, may facilitate the detection of PDAC.

Abstract
Periampullary region encircles a radius of 2 cm around the ampulla of Vater; accordingly, four distinct neoplasias with overlapping imaging features originate in the region. Each of these lesions has a different long-term prognosis; hence, imaging evaluation to characterize the lesion is important. Further certain specific features pertaining to the vascular invasion and systemic spread may decide about the treatment as well as surgical approach. An understanding of the advances in imaging and image processing technology as well as in the methods of image acquisition, for the purpose, is quite relevant towards etching out a rational pre-treatment evaluation protocol. Further, an evidence-based decision as to the choice of optimum modality for answering specific clinical question is of prime importance in achieving a reasonable post-treatment outcome. Pancreatic adenocarcinoma is the fourth most common cancer and a malignancy with one of the least 5-year survival rates (ranging from 6.8 to 15 % depending on peripancreatic extensions, dropping to 1.8 % for metastatic disease). A survival rate of 15-27 % can be achieved if the lesion is resectable but unfortunately, only 10-15 % of patients are eligible for resection. Cystic tumors of pancreas are a rarer variety of pancreatic neoplasia (5-15 % of pancreatic cysts and 1 % of all pancreatic cancers) which have a much better outcome and chances of resection. Being mostly incidentalomas, a timely differentiation of this lesion from the much more common pseudocyst (which would mandate a medical management and a different surgical protocol) is the key for curability. Lastly, the neuroendocrine tumors of pancreas are equally rare (1 % of all pancreatic tumors), but importantly due to associated clinical syndromes and their capability to metastasize early in the course of disease, a timely detection may hence be the key for successful treatment of these lesions. Imaging plays a vital role in the initial detection and characterization as well as in determination of resectability of each of these pancreatic neoplasias. Further, the differentiation of pancreatic head tumors from other periampullary neoplasias is important; the fact that most recurrences are as a result of surgical intervention in an otherwise inoperable disease while most treatment failures are due to improper characterization of the lesion is notable.

Abstract
Treatment of pancreatic ductal adenocarcinoma (PDAC) is increasingly multidisciplinary, with neoadjuvant strategies (chemotherapy, radiation, and surgery) administered in patients with resectable, borderline resectable, or locally advanced disease. The rational supporting this management is the achievement of both higher margin-negative resections and conversion rates into potentially resectable disease and in vivo assessment of novel therapeutics. International guidelines suggest an initial staging of the disease followed by a multidisciplinary approach, even considering the lack of a treatment approach to be considered as standard in this setting. This review will focus on both literature data supporting these guidelines and on new opportunities related to current more active chemotherapy regimens. An analysis of the pathological assessment of response to therapy and the potential role of target therapies and translational biomarkers and ongoing clinical trials of significance will be discussed.

Abstract
BACKGROUND Semiquantitative EUS-elastography has been introduced to distinguish between malignant and benign pancreatic lesions. This study investigated whether semiquantitative EUS-guided transient real time elastography increases the diagnostic accuracy for solid pancreatic lesions compared to EUS-FNA. PATIENTS AND METHODS This single centre prospective cohort study included all patients with solitary pancreatic lesions on EUS during one year. Patients underwent EUS-FNA and semiquantitative EUS-elastography during the same session. EUS and elastography results were compared with final diagnosis which was made on the basis of tissue samples and long-term outcome. RESULTS 91 patients were recruited of which 68 had pancreatic malignancy, 17 showed benign disease and 6 had cystic lesions and were excluded from further analysis. Strain ratios from malignant lesions were significantly higher (24.00; 8.01-43.94 95% CI vs 44.00; 32.42-55.00 95% CI) and ROC analysis indicated optimal cut-off of 24.82 with resulting sensitivity, specificity and accuracy of 77%, 65% and 73% respectively. B-mode EUS and EUS-FNA had an accuracy for the correct diagnosis of malignant lesions of 87% and 85%. When lowering the cut-off strain ratio for elastography to 10 the sensitivity rose to 96% with specificity of 43% and accuracy of 84%, resulting in the least accurate EUS-based method. This was confirmed by pairwise comparison. CONCLUSION Semiquantitative EUS-elastography does not add substantial value to the EUS-based assessment of solid pancreatic lesions when compared to B-mode imaging.

Abstract
BACKGROUND AND AIM Early diagnosis of solid pancreatic lesions (SPLs) enables prompt treatment. The study aims to identify factors differentiating metastatic lesion to the pancreas (PMET) from pancreatic ductal adenocarcinoma (PDAC) and pancreatic neuroendocrine tumors (PNETs). METHODS This is a retrospective study at a tertiary cancer center. Consecutive patients referred for endoscopic ultrasound (EUS) of SPLs from 2004 to 2011 were reviewed. The main outcomes were pre-EUS-FNA (endoscopic ultrasound-guided fine needle aspiration) predictors and diagnostic accuracy of EUS-FNA for PMETs. RESULTS Among a total of 1108 EUS-FNAs for pancreatic lesions, 672 patients had neoplastic SPLs (PMETs = 53; PDACs = 528, PNETs = 91). The sensitivity, specificity, positive predictive value, and accuracy of EUS-FNA for diagnosis of PMETs were 84.9%, 100%, 100%, and 98.8%, respectively. The mean number of EUS-FNA passes for diagnosis of PMET was 3.1 per patient. For each endosonographer, preceding 3-year EUS volume (mean/year) significantly correlated with fewer needle passes (rs [-0.30], P = 0.03). The most common PMET was renal cell carcinoma. Stratified multivariate analyses were performed. Compared with patients with PDACs, PMETs were more common in men (odds ratio [OR] = 2.0; 95% confidence interval [CI] = 1.0-4.0); located in the pancreatic tail (OR = 2.4; 95%CI = 1.1-5.2); and were less likely with increasing age (OR = 0.95; 95%CI = 0.92-0.99), presence of major symptoms (abdomen pain/diarrhea/weight loss; OR = 0.2; 95%CI = 0.1-0.4), elevated bilirubin (OR = 0.3; 95%CI = 0.13-0.69), and imaging evidence of arterial invasion (OR = 0.15; 95%CI = 0.03-0.67). Compared with PNETs, PMETs were more common with increase age (OR = 1.05; 95%CI = 1.02-1.08) and increasing lesion size (OR = 1.03; 95%CI = 1.0-1.1), and were less likely in patients with diabetes (OR = 0.34; 95%CI = 0.11-0.99). CONCLUSION Among the largest numbers of neoplastic SPLs evaluated at a single center, pre-test features reliably characterize, and EUS-FNA provides a highly specific diagnosis of PMETs.

Gut 2015; 64:1105-10.

Abstract
OBJECTIVE Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) allows preoperative tissue confirmation of malignancy, but fear of tumour cell dissemination along the needle track has limited its use. We hypothesised that if tumour cell dissemination occurs with EUS-FNA, survival after complete resection would be impaired. We aimed to evaluate the association of preoperative EUS-FNA with long-term outcomes of patients with resected pancreatic cancer. DESIGN Using the linked Surveillance, Epidemiology, and End Results (SEER)-Medicare data, we identified patients with locoregional pancreatic cancer who underwent curative intent surgery from 1998 to 2009. The patients who received EUS-FNA within the peridiagnostic period were included in the EUS-FNA group. Patients who did not receive EUS evaluation or who underwent EUS without FNA were included in the non-EUS-FNA group. Overall survival and pancreatic cancer-specific survival were compared after controlling for relevant covariates. RESULTS A total of 2034 patients with pancreatic cancer were included (90% pancreatic adenocarcinoma). Of these, 498 (24%) patients were in EUS-FNA group. Patients with multiple comorbidities and more recent diagnosis were more likely to receive EUS-FNA. In multivariate analysis, after controlling for age, race, gender, tumour histology, tumour stage, tumour grade, tumour location, SEER site, year of diagnosis, undergoing percutaneous aspiration/biopsy, Charlson Comorbidity Index, radiation and chemotherapy, EUS-FNA was marginally associated with improved overall survival (HR 0.84, 95% CI 0.72 to 0.99), but did not affect cancer-specific survival (HR 0.87, 95% CI 0.74 to 1.03). CONCLUSIONS Preoperative EUS-FNA was not associated with increased risk of mortality. These data suggest that EUS-FNA can be safely performed for the work-up of suspicious pancreatic lesions.

Abstract
BACKGROUND Endoscopic ultrasound-guided fine-needle aspiration cytology was demonstrated to be a useful tool for the diagnosis and staging of pancreaticobiliary neoplastic lesions. Nonetheless, the diagnostic value of this procedure may be limited by low cellularity of the specimen, contamination of intestinal cells and unfeasibility of ancillary immunocytochemical procedures. The present study was to evaluate its usefulness in the diagnosis of neoplastic lesions. METHODS A series of 46 pancreaticobiliary carcinomas with available cell block preparations was submitted to immunocytochemistry against cytokeratins, carcinoembryonic antigen, E-cadherin, CD10 and p53. The sensitivity, specificity, positive and negative predictive values of the cytological smear in the discrimination of malignant lesions were calculated and compared with those of cell block preparation with the immunocytochemical stains against p53 and CD10. RESULTS According to our findings, the use of cell block preparations together with immunostains against p53 and CD10 allowed to discriminate malignant versus benign specimens with higher sensitivity than the only cytological examination. In detail, CD10 immunostaining was of significant help for the discrimination between cytological contaminants, such as benign gastrointestinal cells, and the neoplastic elements of pancreaticobiliary well differentiated adenocarcinomas. Also, intense nuclear immunoreactivity for p53 was encountered in about 2/3 of the cases and identified pancreatic malignancy with high sensitivity. CONCLUSIONS We suggest that immunocytochemistry against both CD10 and p53 could be applied case by case, mainly to differentiate gastrointestinal and pancreatic benign cellular contaminants showing hyperplasia or reactive changes from differentiated pancreaticobiliary adenocarcinomas.

Abstract
Isolated pancreatic tuberculosis (TB) is considered an extremely rare condition, even in the developing countries. Most reported cases of pancreatic TB are diagnosed after exploratory laparotomy or autopsy. Pancreatic TB is a potential mimic of invasive pancreatic malignancy and the presence of vascular invasion does not distinguish one condition from the other. Every effort should be made for the earliest diagnosis of this condition as TB is a treatable condition and it avoids unnecessary management of pancreatic carcinoma. Here we report a rare case of primary pancreatic head TB in a 58-year-old male who presented with hypodense lesion in head of pancreas with double duct sign and portal vein invasion mimicking non-resectable pancreatic carcinoma.

Abstract
INTRODUCTION While laparoscopy-assisted endoscopic retrograde cholangiopancreatography can be performed for the diagnosis and management of pancreaticobiliary diseases in patients with Roux-en-Y (RY) anatomy; the technical feasibility of performing laparoscopy-assisted endoscopic ultrasound (EUS) is unknown. METHODS In this report, we describe the technique for performing laparoscopy-assisted EUS in two patients with RY gastric bypass anatomy who presented with obstructive jaundice, abnormal liver function tests, and dilated biliary tree. RESULTS While the examination was normal in one patient, EUS-guided fine needle aspiration of pancreatic head mass revealed adenocarcinoma in the other. DISCUSSION Laparoscopic assisted EUS examination including FNA is feasible in Roux-en-Y surgical anatomy.

Abstract
Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) has evolved to become an indispensable tool for tissue acquisition. While the overall diagnostic accuracy of EUS-FNA is greater than 90% for lung cancer staging, it is lower for pancreatic mass lesions. Several factors such as location of the tumor, disease characteristics and procedural techniques determine the outcomes of EUS-FNA. In this review we evaluate the various technical factors that are keys to attaining optimal procedural outcomes.

Abstract
Introduction. Celiac plexus neurolysis is used in pain management of patients with advanced and unresectable pancreatic cancer. We retrospectively analyzed efficacy and safety of endoscopic ultrasound- (EUS-) guided celiac plexus neurolysis in patients treated in our unit. Methods. Twenty nine subjects with unresectable pancreatic cancer and severe pain despite pharmacological treatment underwent EUS-guided celiac plexus neurolysis with 98% ethanol. Patients scored their pain according to a 0-10 point scale and were interviewed 1-2 weeks and 2-3 months after the procedure. Results. Twenty five (86%) patients reported improvement in their pain at 1-2 weeks following the procedure. Of these, 7 (24%) reported substantial improvement (decrease in pain by more than 50%) and 4 (14%) complete disappearance of pain. Pain relief was still present in 76% of patients after 2-3 months. Treatment-related side effects included hypotonia in 1 patient, severe pain immediately postprocedure in 2 patients, and short episodes of diarrhea in 3 patients. Conclusion. Endoscopic ultrasound- (EUS-) guided celiac plexus neurolysis is a safe and effective treatment of severe pain from advanced pancreatic cancer.

Abstract
Chronic pancreatitis (CP) is progressive inflammatory process of the pancreas. Abdominal pain remains the most debilitating symptom affecting quality of life, apart from diabetes mellitus, steatorrhoea and weight loss. The treatment options have evolved over the past decades and are aimed to provide durable relief in pain with possible attempt to support or improve the failing endocrine and exocrine functions. Surgical treatment options have shown the potentials to provide superior long term results compared to the pharmacological and endoscopic modalities and are broadly divided in to drainage, resection and combination hybrid procedures. The choice is based on the morphology of the main pancreatic duct, presence of head mass and associated complication of CP. Knowing the basic nature of the disease, total pancreatectomy seems a curative option but not without significant morbidities. There is recent paradigm shift towards organ sparing surgical procedures with reasonable success. Despite recent advancement in the treatment modalities for CP the overall quality of life remains moderate which need further addressal.

Abstract
Background: Metastases to the pancreas are an uncommon cause of pancreatic masses seen on endoscopic ultrasound (EUS)-guided fine-needle aspiration (FNA). The purpose of this study is to retrospectively review the cytomorphology, clinical findings, and results of ancillary studies in a large series of these unusual cases. Materials and Methods: We searched our institution's pathology database for EUS-guided FNAs of the pancreas that were diagnostic of metastatic tumor over a 5-year period. The final cytologic diagnosis, results of ancillary studies, corresponding histological material, and clinical follow-up data were reviewed in these cases. Results: A total of 1172 pancreatic EUS-guided FNAs were identified, of which 25 cases (2.1%) had a confirmed diagnosis of a pancreatic metastasis. This included 12 (48%) cases of renal cell carcinoma, 3 (12%) melanomas, 3 (12%) small cell carcinomas, and 7 (28%) other malignancies. In these metastatic tumors involving the pancreas, 20 (80%) of the lesions were solitary. Four (16%) cases had no prior history of malignancy. The average time to diagnosis of pancreatic metastasis was 5.3 years. Immunohistochemistry and special stains were performed in 22 (88%) and 9 (36%) cases, respectively. Conclusions: Our data shows that although metastases to the pancreas are rare, they can present as a solitary mass many years after the primary malignancy is diagnosed and can even be the first manifestation of an extrapancreatic primary in a small number of cases. It is important to consider the possibility of a metastatic lesion in the pancreas because this may require a different management than a primary pancreatic tumor.

Abstract
BACKGROUND Unnecessary laparotomy in patients with advanced pancreatic cancer may both compromise the quality of life and delay the initiation of more appropriate therapy. Very often, peritoneal small liver metastases and true local status cannot be fully determined without surgery. Laparoscopy may spare laparotomy and decrease morbidity for patients with nonresectable advanced disease. The aim of this study was to determine the impact of laparoscopy in patients with potentially resectable adenocarcinoma of the pancreas. MATERIALS AND METHODS We reviewed the records of patients undergoing pancreatic surgery at the University of Nebraska Medical Center from October 2001 to April 2005. A total of 59 patients were included in the study. All patients were staged radiographically with a high resolution helical computed tomography scan and their tumors were considered resectable. Thirty-seven patients underwent staging laparoscopy while 22 proceeded directly to laparotomy. RESULTS Of the 37 patients who underwent laparoscopic staging, 9 (24.3%) were detected to have metastatic disease or advanced tumor; the remaining 28 (75.7%) patients with negative laparoscopy proceeded to laparotomy. Of those, 24 patients (85.7%) underwent pancreatic resection with curative intent, while 4 patients had metastatic or locally advanced disease at subsequent laparotomy which was missed on staging laparoscopy (false negative rate of 14.3%). Of the 22 patients who proceeded directly to laparotomy, 16 (72.7%) received curative Whipple resection and 6 (27.3%) were found to have advanced disease and received bypass procedures or biopsy alone. CONCLUSION These findings suggest that staging laparoscopy is beneficial in a significant proportion of patients deemed resectable by routine noninvasive preoperative studies. We plan to add intraoperative laparoscopic ultrasound to our staging protocol in order to decrease the false negative rate.

Abstract
Pancreatic cancer is the fourth leading cause of cancer death in the United States. In 2008, an estimated 34,290 people died from pancreatic cancer and 37,680 new cases were diagnosed. Despite modern treatment, 90% of patients die within 1 year of diagnosis. Pancreatectomy is still the only potentially curative approach, but most patients have incurable disease by the time they are diagnosed, and fewer than 20% are candidates for surgery. In the present paper the English-language literature addressing the medical management in pancreatic cancer was reviewed. Based on these data we will discuss the role of currently used chemotherapy and target therapy in pancreatic cancer, as well as perspectives of the emerging strategies that are arising in order to improve the outcomes of this complex disease.

Abstract
BACKGROUND The objectives of this study were to evaluate the role of endoscopic ultrasonography (EUS)-guided fine-needle aspiration (FNA) in the preoperative diagnosis of pancreatic endocrine tumors (PETs) and to investigate whether the Ki-67 index determined on cytologic material could help predict their behavior. METHODS The study included 10 men and 5 women (ratio of men to women, 2:1) with a mean age of 62.4 years (range, 40-79 years). Diff-Quik- and Papanicolaou-stained FNA samples were analyzed retrospectively, and immunocytochemical stains were performed for chromogranin A, synaptophysin, vimentin, alpha-1-antitrypsin, and Ki-67 on cell block sections. The Ki-67 index was evaluated by using digital image-analysis software and was correlated with follow-up (mean, 21.5 months; range, 2-43 months). RESULTS The overall survival was rate 86.7% (13 of 15 patients). Seven of 15 patients (46.7%) patients developed lymph node and/or hematogenous metastases. The Ki-67 index in PETs with no metastases was lower (mean, 6.3%; range, 2%-13%) than in clinically aggressive (metastatic) tumors (mean, 7.7%; range, 3%-27%; P = .03). None of the tumors that had a Ki-67 index < or =2% were metastatic. Both patients who died of disease had a Ki-67 index of 4%. CONCLUSIONS Although tumors with metastatic potential tended to exhibit a slightly higher Ki-67 index, there was a significant overlap with nonmetastatic tumors, and PETs that had a very low proliferative rate still could behave aggressively; therefore, the authors concluded that the Ki-67 index does not predict the risk of disease progression in patients with PETs.

Abstract
BACKGROUND AND AIM We report our single-centre experience with endoscopic ultrasound guided fine needle aspiration (EUS-FNA) of solid pancreatic lesions with regard to clinical utility, diagnostic accuracy and safety. METHODS We prospectively reviewed data on 100 consecutive EUS-FNA procedures performed in 93 patients (54 men, mean age 60.6 +/- 12.9 years) for evaluation of solid pancreatic lesions. Final diagnosis was based on a composite standard: histologic evidence at surgery, or non-equivocal malignant cytology on FNA and follow-up. The operating characteristics of EUS-FNA were determined. RESULTS The location of the lesions was pancreatic head in 73% of cases, the body in 20% and the tail in 7%. Mean lesion size was 35.1 +/- 12.9 mm. The final diagnosis revealed malignancy in 87 cases, including adenocarcinomas (80.5%), neuroendocrine tumours (11.5%), lymphomas (3.4%) and other types (4.6%). The FNA findings were: 82% interpreted as malignant cytology, 1% as suspicious for neoplasia, 1% as atypical, 7% as benign process and 9% as non-diagnostic. No false-positive results were observed. There was a false-negative rate of 5%. Sensitivity, specificity, positive predictive value, negative predictive value and accuracy were 94.3%, 100%, 100%, 72.2% and 95%, respectively. In 23 (88.5%) of 26 aspirated lymph nodes malignancy was found. Minor complications occurred in two patients. CONCLUSIONS Our experience confirms that EUS-FNA in patients with suspected solid pancreatic lesions is safe and has a high diagnostic accuracy. This technique should be considered the preferred test when a cytological diagnosis of a pancreatic mass lesion is required.

Abstract
Early diagnosis of pancreatic cancer remains a difficult task, and multiple imaging tests have been proposed over the years. The aim of this review is to describe the current role of endoscopic ultrasound (EUS) for the diagnosis and staging of patients with pancreatic cancer. A detailed search of MEDLINE between 1980 and 2007 was performed using the following keywords: pancreatic cancer, endoscopic ultrasound, diagnosis, and staging. References of the selected articles were also browsed and consulted. Despite progress made with other imaging methods, EUS is still considered to be superior for the detection of clinically suspected lesions, especially if the results of other cross-sectional imaging modalities are equivocal. The major advantage of EUS is the high negative predictive value that approaches 100%, indicating that the absence of a focal mass reliably excludes pancreatic cancer. The introduction of EUS-guided fine needle aspiration allows a preoperative diagnosis in patients with resectable cancer, as well as a confirmation of diagnosis before chemoradiotherapy for those that are not. This comprehensive review highlighted the diagnostic capabilities of EUS including the newest refinements such as contrast-enhanced EUS, EUS elastography, and 3-dimensional EUS. The place of EUS-guided biopsy is also emphasized, including the addition of molecular marker techniques.

Abstract
Pancreatic adenocarcinoma is one of the leading causes of cancer death in the West, with a poor overall 5-year survival rate of only 4%. Late clinical presentation with an advanced disease results in a low rate of surgical intervention. Tumor serum marker CA 19-9 is sensitive, although not specific for the diagnosis of adenocarcinomas of the pancreas. The treatment approach is based on whether the tumor is resectable or non-resectable at presentation. Therefore, imaging plays a crucial role in the management of this disease. Many modalities are available to image the pancreas. They include non-invasive techniques, like ultrasound, contrast-enhanced multidetector computed tomography, magnetic resonance imaging and integrated positron emission tomography/computed tomography, and invasive techniques, like endoscopic retrograde cholangiopancreatography and endoscopic ultrasound. Each of these modalities has its peculiar strengths and weaknesses.

Abstract
Endoscopic ultrasound (EUS) has developed significantly over the last two decades and has had a considerable impact on the imaging and staging of mass lesions within or in close proximity to the gastrointestinal (GI) tract. In conjunction with conventional imaging such as helical computed tomography and magnetic resonance imaging, the indications for EUS include (1) differentiating between benign and malignant lesions of the mediastinum and upper GI tract, (2) staging malignant tumors of the lung, esophagus, stomach, and pancreas prior to surgery or oncological treatment, (3) excluding common bile duct stones before laparoscopic cholecystectomy, thereby avoiding the need for endoscopic retrograde cholangiopancreatography (ERCP) in some patients, and (4) assessing suspected lesions that are either equivocal or not seen on conventional imaging. In recent years, EUS has charted a course similar to that taken by ERCP, evolving from a purely diagnostic modality to one that is interventional and therapeutic. These indications include (5) obtaining a tissue diagnosis by EUS-guided fine-needle aspiration or trucut-type needle biopsy and (6) providing therapy such as coeliac plexus neurolysis and pancreatic pseudocyst drainage--in many cases, more accurately and safely than conventional techniques. Emerging investigational techniques include EUS-guided enteric anastomosis formation and fine-needle injection therapy for malignant disease.

Abstract
Endoscopic ultrasound (EUS) has been developed since the early 1980s. Its clinical role in the diagnosis of gastrointestinal wall lesions and staging of gastrointestinal and lung cancer has evolved over the last two decades. Initially, it was either used as an imaging tool for gastrointestinal wall lesions or for staging of gastrointestinal tumours. However, in combination with fine-needle aspiration under real-time scanning, EUS is now being used in tissue sampling for diagnosis. In addition, EUS may be used therapeutically in coeliac plexus neurolysis or pseudocyst drainage. This review concentrates on the current applications of EUS.

Abstract
BACKGROUND AND AIM For reduction in cost, time and risk of complications, the number of endoscopic ultrasound (EUS)-guided fine-needle aspiration (FNA) passes should be minimized. Previous studies have shown that tumor differentiation and site of aspiration will affect the number of passes in patients with pancreatic cancer. There have been no reports that EUS features of pancreatic malignancies per se will influence the number of passes. Our aim was to prospectively assess various factors that would affect the number of passes in patients with pancreatic cancer. METHODS Between May 2003 and December 2004, 41 patients with presumed pancreatic cancer were studied. EUS-guided FNA was performed with an Olympus GF-UC2000P echoendoscope and a 22-gauge needle. On-site assessment of the specimen by a cytopathologist was available during the procedure. RESULTS Adenocarcinomas were confirmed in 25 patients. Pancreatic adenocarcinomas with intratumoral anechoic foci required a higher number of diagnostic passes than those without anechoic change (3.40 vs 2.27, P < 0.05). An average of 4.00 FNA passes for diagnosing a well-differentiated adenocarcinoma was also significantly higher than the 2.40 diagnostic passes for a moderately differentiated adenocarcinoma and the 2.00 passes for a poorly differentiated one (P < 0.05). CONCLUSIONS The existence of intratumoral anechoic foci was not a rare finding under detailed EUS investigation of pancreatic cancer. Both the existence of intratumoral anechoic foci and the differentiation of the cancer are significant predictive factors for the number of diagnostic EUS-FNA passes.

Abstract
This review discusses the current imaging modalities for the diagnosis and staging of solid and cystic pancreatic lesions and for the assessment of acute and chronic pancreatitis, and the future role of emerging technologies in the management of pancreatic diseases. Multidetector row spiral computed tomography is superior to conventional single-detector row spiral computed tomography in the detection and staging of pancreatic adenocarcinoma. Positron emission tomography is a sensitive but relatively nonspecific diagnostic modality. Positron emission tomography-computed tomography fusion may improve the staging accuracy for pancreatic cancer. Echo-enhanced ultrasound may have an emerging role in evaluating pancreatic masses. Endoscopic ultrasound with fine needle aspiration for cytology is the single best method for diagnosis and staging of nonmetastatic pancreatic cancer with a high accuracy for determining tumor resectability. In acute pancreatitis, a modification of the standard computed tomography severity index, which places greater emphasis on extrapancreatic complications, has shown superior correlation with various patient outcome measures. Endoscopic retrograde cholangiopancreatography is still the test of choice for morphological evaluation of chronic pancreatitis, whereas magnetic resonance cholangiopancreatography offers a noninvasive alternative in selected patients. Endoscopic ultrasound can be useful for detecting early chronic pancreatitis. Secretin-stimulated imaging techniques may eventually provide a noninvasive method of reliably assessing pancreatic exocrine function.

Abstract
This review, based on the Hennepin County Medical Center experience and review of the literature, vastly covers the up-to-date role of endoscopic ultrasonography (EUS) and EUS-guided fine-needle aspiration (FNA) in evaluating tumorous lesions of the gastrointestinal tract and adjacent organs. Emphasis is given to the tumoral and nodal staging of esophageal, pulmonary, and pancreatic cancer. This review also discusses technical, pathological, and gastroenterologic aspects and the role of the pathologist and endosonographer in the evaluation of these lesions, as well as the corresponding FNA cytology and differential diagnosis.

Evaluation of: Canto MI, Goggins M, Yeo CJ et al.: Screening for pancreatic neoplasia in high-risk individuals: an EUS-based approach. Clin. Gastroenterol. Hepatol. 2(7), 606-621 (2004). Endoscopic ultrasound was utilized in the screening of individuals at high risk for pancreatic cancer. Patients with abnormal endoscopic ultrasound findings were further evaluated with fine-needle biopsy, endoscopic retrograde cholangipancreatography, and computerized tomography scanning. A total of 38 patients were enrolled in this prospective screening program. A total of seven patients were identified with suspicious neoplastic lesions and underwent pancreatic resection. No significant morbidity or mortality resulted from the screening tests or subsequent intervention including surgery. Surgical pathology revealed two neoplastic masses (invasive carcinoma and intraductal pancreatic mucinous neoplasm), three pancreatic intraepithelial neoplastic lesions, and two benign lesions for a diagnostic yield of 13.1% (five of 38). The patient with invasive carcinoma remains disease free over 5 years following surgery. The results of this study suggest a reasonable approach to detecting early neoplastic lesions in asymptomatic individuals. Such early intervention efforts hold much potential in reducing the mortality of this aggressive disease. Further studies are needed to confirm the suggested clinical benefit of screening and to answer questions related to specific screening protocols.

Abstract
BACKGROUND & AIMS Pancreatic adenocarcinoma is a most devastating cancer that presents late and is rapidly progressive. This study aimed to identify unique, tissue-specific protein biomarkers capable of differentiating pancreatic adenocarcinoma (PC) from adjacent uninvolved pancreatic tissue (AP), benign pancreatic disease (B), and nonmalignant tumor tissue (NM). METHODS Tissue samples representing PC (n = 31), AP (n = 44), and B (n = 19) tissue were analyzed on hydrophobic protein chip arrays by surface-enhanced laser desorption/ionization time-of-flight mass spectrometry. Training models were developed using logistic regression and validated using the 10-fold cross-validation approach. RESULTS The hydrophobic protein chip array revealed 13 protein peaks differentially expressed between PC and AP (receiver operating characteristic [ROC] area under the curve [AUC], 0.64-0.85), 8 between PC and B (ROC AUC, 0.67-0.78), and 12 between PC and NM tissue (ROC AUC, 0.63-0.81). Logistic regression and cross-validation identified overlapping panels of peaks to develop a training model that distinguished PC from AP (77.4% sensitivity, 84.1% specificity), B (83.9% sensitivity, 78.9% specificity), and NM tissue (58.1% sensitivity, 90.5% specificity). The final panels selected correctly classified 80.6% of PC and 88.6% of AP samples (ROC AUC, 0.92), 93.5% of PC and 89.5% of B samples (ROC AUC, 0.99), and 71.0% of PC and 92.1% of NM samples (ROC AUC, 0.91). CONCLUSIONS This study used surface-enhanced laser desorption/ionization time-of-flight mass spectrometry to discover a number of protein panels that can distinguish effectively between pancreatic adenocarcinoma, benign, and adjacent pancreatic tissue. Identification of these proteins will add to our understanding of the biology of pancreatic cancer. Furthermore, these protein panels may have important diagnostic implications.

Abstract
BACKGROUND & AIMS The clinical significance of "fullness" or enlargement of the pancreas (FP/EP) is not well established. The objective of this study was to report our experience with endoscopic ultrasonography (EUS) in evaluating patients referred for FP/EP found on computed tomography (CT). METHODS Patients referred to our center for EUS evaluation of FP/EP between January 1998 and December 2003 were studied. Patient demographics, clinical history, endoscopic findings, and follow-up were recorded. Multivariate analysis was used to identify predictors of pancreatic malignancy. RESULTS A total of 50 patients: 46% (23/50) male, mean age 59 years (range, 18-90) made up our studied population. EUS demonstrated normal findings in 42% (21/50), prominent ventral anlage (embryologic variant) in 14% (7/50), and chronic pancreatitis in 22% (11/50). In 22% (11/50), a suspicious mass was noted and fine-needle aspiration (FNA) was performed. Cytology revealed chronic inflammation in 7 patients, while adenocarcinoma was found in the remaining 4. Median follow-up was 27 months, and the diagnosis did not change in any of the 50 patients. There were no procedure-related complications. After multivariant regression analysis, the factors that were statistically associated with malignancy were a CA19-9 level >300 (P = .0002) and weight loss (P < .006). CONCLUSIONS The majority of patients presenting with FP/EP had benign disease, but 8% had pancreatic cancer. Elevated CA19-9 and weight loss were predictive of pancreatic malignancy. EUS and EUS-FNA are safe and accurate diagnostic tests and can play an important role in evaluating patients with FP/EP.

Abstract
Pancreas cancer is the fourth leading cancer killer in adults. Cure of pancreas cancer is dependent on the complete surgical removal of localized tumor. A complete surgical resection is dependent on accurate preoperative and intra-operative imaging of tumor and its relationship to vital structures. Imaging of pancreatic tumors preoperatively and intra-operatively is achieved by pancreatic protocol computed tomography (CT), endoscopic ultrasound (EUS), laparoscopic ultrasound (LUS), and intra-operative ultrasound (IOUS). Multi-detector CT with three-dimensional (3-D) reconstruction of images is the most useful preoperative modality to assess resectability. It has a sensitivity and specificity of 90 and 99%, respectively. It is not observer dependent. The images predict operative findings. EUS and LUS have sensitivities of 77 and 78%, respectively. They both have a very high specificity. Further, EUS has the ability to biopsy tumor and obtain a definitive tissue diagnosis. IOUS is a very sensitive (93%) method to assess tumor resectability during surgery. It adds little time and no morbidity to the operation. It greatly facilitates the intra-operative decision-making. In reality, each of these methods adds some information to help in determining the extent of tumor and the surgeon's ability to remove it. We rely on pancreatic protocol CT with 3-D reconstruction and either EUS or IOUS depending on the tumor location and operability of the tumor and patient. With these modern imaging modalities, it is now possible to avoid major operations that only determine an inoperable tumor. With proper preoperative selection, surgery is able to remove tumor in the majority of patients.

Abstract
Tumors of the small intestine are rare as compared to malignant tumors of the pancreas. Here we report on the case of a 61-year-old man suffering from chronic pancreatitis presenting with a lesion projecting into the pancreatic head shown by both computed tomography and transabdominal ultrasound. Pancreatic cancer was suspected, but endoscopic ultrasound revealed this lesion to be situated in the submucosal layer of the duodenal wall. Surgery was performed since biopsy of this lesion was not diagnostic and a malignant leiomyosarcoma could therefore not be excluded. Limited surgery comprised resection of the duodenal lesion, whereas based on computed tomography alone, exploration of the pancreas would have been performed. Thus, in the present case endoscopic ultrasound leads to a more appropriate, less invasive therapeutic measure.

Abstract
Pancreatic cancer remains a devastating and difficult disease to diagnose and successfully treat. Its incidence increases with age, with 60% of patients being over the age of 65 at presentation. Due to the insidious nature and asymptomatic onset of pancreatic cancer approximately 85% of patients present with disseminated or locally advanced disease resulting in a very poor prognosis. In the past the elderly patient, who may be felt to be too frail for operative procedures or further therapy, may have missed out on optimal treatment. In this article we review the investigation and treatment of pancreatic cancer and examine current evidence with regard to pancreatic cancer in the elderly. The evidence suggests that surgical resection can be performed safely in patients who are fit for surgery in specialist centres but may require more intensive post-operative rehabilitation.
