Abstract
Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is an accurate technique for sampling the pancreas and mediastinum; however, limited data are available for other mass lesions. The aim of this study was to explore the value of EUS-FNA in the differential diagnosis of all mass lesions. Data from patients who underwent EUS-FNA for the diagnosis of mass lesions, including pancreatic, mediastinal, celiac and retroperitoneal lesions were retrospectively analyzed. The accuracy was calculated by comparing the results of FNA with the results of pathological examination or follow-up surveillances in non-operated cases. A total of 150 cases were included. The location of the mass varied from the pancreas (n=62) to the mediastinum (n=29), gastrointestinal tract (n=36), celiac cavity and retroperitoneum (n=23). The sensitivity and Youdens index of EUS-FNA in the diagnosis of all lesions were 92.97% and 0.93 respectively. The accuracy of diagnosis of pancreatic, mediastinal, gastrointestinal, celiac and retroperitoneal lesions was 85.48, 89.66, 83.33 and 78.23%, respectively. Masses were categorized into parenchymal organs (n=66), luminal organs (n=36) and enlarged lymph nodes (n=33). Lesions in parenchymal organs were likely to be bigger than those in luminal organs (P=0.03) and enlarged lymph nodes (P=0.01). For solid and cystic masses, which constituted 63.3 and 14.7% of the total masses, no significant difference in diagnostic accuracy was observed (P=0.56); however, lesion sizes were significantly different between these two groups (P=0.04) and the majority of cystic masses were identified in women (P=0.03). Malignant lesions were more common in older (P=0.01) and male (P=0.03) patients. In conclusion, EUS-FNA is an effective tool in the diagnosis of unexplained mass lesions; it influences the management of patients by enabling the appropriate treatment to be identified.

Abstract
Pancreatic cancer is still a highly lethal disease with a 5-year survival rate of approximately 5 %. Early detection offers one of the best hopes for improving survival. Previous cohort studies and case-control studies showed that 4-10 % of pancreatic cancers have a hereditary basis, and individuals with a family history have an increased risk of developing pancreatic and extra-pancreatic malignancies. Since individuals with a family history of pancreatic cancer and those with a known genetic syndrome that predisposes to pancreatic cancer will be the first to benefit from early detection tests as they become available, familial pancreatic cancer (FPC) registries have been established in the US and Europe, but not yet in Japan. Such registries form the basis for epidemiological studies, clinical trials, and basic research on familial pancreatic cancer. There is a need for FPC registries in Japan as cancer risk varies among different populations and discoveries made in Western populations may not translate to the Japanese population. These registries in Japan will align with ongoing international efforts and add to a better understanding of the natural history, risk factors, screening strategies, and responsible genes, for improving survival of this dismal disease.

Abstract
Background and Objectives: Diagnosis of pancreatic lesions remains a clinical challenge. This study aimed to evaluate the diagnostic accuracy of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) in pancreatic mass lesions. Patients and Methods: Clinical data, laboratory tests, and cytopathological and imaging reports were collected from 185 pancreatic EUS cases performed from March 2010 to January 2014. The final diagnosis was based on surgical findings, EUS-FNA or computed tomography (CT)-guided biopsy. Results: A total of 100 pancreatic FNAs were obtained by EUS. Most positive diagnoses of malignancy were pancreatic adenocarcinomas (n = 61). The site of pancreatic adenocarcinoma was the head in 50 (82.0%), body in seven (11.5%), and tail in four (6.5%). The sensitivity, specificity, and positive and negative predictive values of EUS-FNA for diagnosing adenocarcinoma were 80.3%, 92.3%, 94.2%, and 75.0%, respectively. Discussion: We concluded that EUS-FNA of pancreatic lesion accurately diagnoses pancreatic adenocarcinoma and should be considered for the standard management of pancreatic adenocarcinoma.

Abstract
INTRODUCTION Pancreatic neuroendocrine tumors are a diverse group of malignant neoplasms of varying biological behavior, with outcomes predicted by tumor differentiation and grade. Initial diagnosis is often made by fine-needle aspiration cytology via endoscopic ultrasound of the pancreas primary. We retrospectively reviewed our institutional experience with pancreatic neuroendocrine cytology diagnosis and evaluated for tumor typing accuracy and causes of misdiagnosis. MATERIALS AND METHODS We searched our institutional database (1994-2012) for all pancreas fine-needle aspirations with corresponding pancreatic histology and a neuroendocrine diagnosis. Cases with discrepant cytology and histology diagnoses were reviewed for factors contributing to misclassification. RESULTS 143 patients were identified with a neuroendocrine diagnosis either by cytology or histology. In the 129 cytology cases classified as positive/neoplastic/suspicious, tumor type was diagnosed correctly in 101 (78%) cases, incorrectly in 17 (13%), and unclassified (epithelioid neoplasm) in 11 (9%). The most common tumor classification error (7 cases) was misclassifying a neuroendocrine tumor as adenocarcinoma on cytology, which in one case led to inappropriate neoadjuvant chemotherapy. Features of neuroendocrine cytology misdiagnosed as adenocarcinoma included cell clustering and anisonucleosis. Features of non-neuroendocrine cytology misclassified as neuroendocrine included abundant acinar cells or problematic interpretation of immunohistochemical stains. CONCLUSIONS Cytology can accurately identify neuroendocrine differentiation in the majority of cases; nevertheless, there are potential serious pitfalls. Misclassification of a neuroendocrine tumor as adenocarcinoma or vice versa can have significant clinical impact. Clinical and radiological correlation is essential.

Abstract
Endoscopic ultrasound (EUS) has become an important component in the diagnosis and treatment of carcinoma pancreas. With the advent of advanced imaging techniques and tissue acquisition methods the role of EUS is becoming increasingly important. Small pancreatic tumors can be reliably diagnosed with EUS. EUS guided fine needle aspiration establishes diagnosis in some cases. EUS plays an important role in staging of carcinoma pancreas and in some important therapeutic methods that include celiac plexus neurolysis, EUS guided biliary drainage and drug delivery. In this review we attempt to review the role of EUS in diagnosis and management of carcinoma pancreas.

Abstract
Background: The treatment of pancreatic cancer represents a major objective in clinical research, as it still remains the fourth leading cause of cancer deaths among men and women, with approximately 6% of all cancer-related deaths. Materials and Methods: We studied the assessment of an endoscopic ultrasound (EUS)-guided radiofrequency ablation (RFA) probe through a 19G needle in order to achieve a desirable necrosis area in the pancreas. Radiofrequency ablation of the head of the pancreas was performed on 10 Yorkshire pigs with a weight between 25 kg and 35 kg and a length of 40-70 cm. Using an EUS-guided RFA experimental probe, we ablated an area of 2-3 cm width. The biological samples were harvested after 3 days and 5 days and necropsy was performed 1 week after the procedure. Results: All pigs showed no significant change regarding their behavior and no signs of complication was encountered. Blood analysis revealed increased values of amylase, alkaline phosphatase, and gamma-glutamyl transpeptidase on the 3rd day but a decrease on the 5th day. After necropsy and isolation of the pancreas, the ablated area was easily found, describing a solid necrosis. The pathological examination revealed a coagulative necrosis area with minimal invasion and inflammatory tissue at about 2 cm surrounding the lesion. Conclusion: EUS-RFA is a feasible technique and might represent a promising therapy for the future treatment of pancreatic cancer. However, further studies are necessary to investigate EUS-guided RFA as an option for palliation in pancreatic cancer until it can be successfully used in human patients.

Abstract
The incidence of pancreatic tuberculosis is low. Pancreatic tuberculosis often presents as a pancreatic mass. If patients have no history of tuberculosis, pancreatic tuberculosis is often misdiagnosed as a pancreatic tumor. Only after surgery it can be diagnosed correctly. Endoscopic ultrasonography guided fine needle aspiration (EUS-FNA) allows for biopsy of pancreatic tissue to conduct pathological examination, thus providing clinical evidence for the diagnosis of pancreas diseases. Compared with ultrasound and CT guided puncture, EUS-FNA has advantages of high accuracy and fewer complications.

Abstract
BACKGROUND Endoscopic ultrasound-guided fine-needle aspiration biopsy (EUS-FNA) is the preferred method for biopsying the gastrointestinal tract, and rapid on-site cytological evaluation is considered standard practice. Our institution does not perform on-site evaluation; this study analyzes our overall diagnostic yield, accuracy, and incidence of nondiagnostic cases to determine the validity of this strategy. DESIGN Data encompassing clinical information, procedural records, and cytological assessment were analyzed for gastrointestinal EUS-FNA procedures (n = 85) performed at Vancouver General Hospital from January 2012 to January 2013. We compared our results with those of studies that had on-site evaluation and studies that did not have on-site evaluation. RESULTS Eighty-five biopsies were performed in 78 patients, from sites that included the pancreas, the stomach, the duodenum, lymph nodes, and retroperitoneal masses. Malignancies were diagnosed in 45 (53%) biopsies, while 24 (29%) encompassed benign entities. Suspicious and atypical results were recorded in 8 (9%) and 6 (7%) cases, respectively. Only 2 (2%) cases received a cytological diagnosis of 'nondiagnostic'. Our overall accuracy was 72%, our diagnostic yield was 98%, and our nondiagnostic rate was 2%. Our results did not significantly differ from those of studies that did have on-site evaluation. CONCLUSION Our study highlights that adequate diagnostic accuracy can be achieved without on-site evaluation.

Abstract
The recent advances in pancreas cytology specimen sampling methods have enabled a specific cytologic diagnosis in most cases. Proper triage and processing of the cytologic specimen is pivotal in making a diagnosis due to the need for ancillary testing in addition to cytological evaluation, which is especially true in the diagnosis of pancreatic cysts. Newly proposed terminology for pancreaticobiliary cytology offers a standardized language for reporting that aims to improve communication among patient caregivers and provide for increased flexibility in patient management. This review focuses on these updates in pancreas cytology for the optimal evaluation of solid and cystic lesions of the pancreas.

Abstract
OBJECTIVES Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is accurate in cytological diagnosis of pancreatic lesions. Our aim was to determine optimal number of needle passes in EUS-FNA for pancreatic lesions without onsite cytopathologist, who is not routinely available to participate in the procedure. METHODS Results of all needle passes in EUS-FNAs for 117 pancreatic neoplasms in 115 patients were reviewed retrospectively. Factors that required 2 or more needle passes for correct diagnosis were identified by multivariate logistic regression analysis. In each lesion group defined by the factors that required 2 or more passes and were known at the time of EUS-FNA, number of needle passes was regarded as optimal when an increase in diagnostic sensitivity by an additional needle pass did not reach 10%. RESULTS Size of 15 mm or less (OR 4.58, 95% CI 1.70-12.3, P < 0.01), location of head (OR 5.02, 95% CI 1.82-13.9, P < 0.01), and neuroendocrine tumor (NET) (OR 5.04, 95% CI 1.38-18.4, P = 0.01) independently required 2 or more needle passes. Optimal numbers of needle passes for lesions of 15 mm or less in the head, those of more than 15 mm in the head, those of 15 mm or less in the body or tail, and those of more than 15 mm in the body or tail were 3, 2, 2, and 1, respectively. When these numbers of needle passes were performed, 93% of pancreatic lesions were correctly diagnosed. CONCLUSIONS Optimal numbers of needle passes in EUS-FNA for pancreatic lesions without onsite cytopathologist were between 1 and 3.

Abstract
BACKGROUND The negative predictive value of endoscopic ultrasonography-guided fine needle aspiration for the diagnosis of solid pancreatic lesions remains low, and the biopsy specimens are sometimes inadequate for appropriate pathological diagnosis. AIMS To evaluate the usefulness of a novel method of contrast-enhanced harmonic endoscopic ultrasonography-guided fine-needle aspiration for the differential diagnosis and adequate sampling of solid pancreatic lesions. METHODS Patients with a diagnosis of solid pancreatic lesions who underwent fine-needle aspiration guided by contrast-enhanced harmonic endoscopic ultrasonography or by endoscopic ultrasonography from October 2010 to July 2013 were retrospectively identified and classified into the CH-EUS or EUS group, respectively. Surgical pathology and/or follow-up results were defined as the final diagnosis. Operating characteristics and adequacy of biopsy specimens by fine-needle aspiration were compared between the two groups. RESULTS Operating characteristics for contrast-enhanced harmonic endoscopic ultrasonography-guided fine-needle aspiration in solid pancreatic lesions were as follows: area under the curve = 0.908, sensitivity = 81.6%, specificity = 100%, positive predictive value = 100%, negative predictive value = 74.1%, and accuracy = 87.9%. The percentage of adequate biopsy specimens in the CH-EUS group (96.6%) was greater than that in the EUS group (86.7%). CONCLUSION Simultaneous contrast-enhanced harmonic endoscopic ultrasonography during fine-needle aspiration is useful for improving the diagnostic yield and adequate sampling of solid pancreatic lesions.

A microRNA-based test improves endoscopic ultrasound-guided cytologic diagnosis of pancreatic cancer. Clin Gastroenterol Hepatol 2014; 12:1717-23. [PMID: 24662333 DOI: 10.1016/j.cgh.2014.02.038] [Citation(s) in RCA: 31] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/02/2013] [Revised: 02/26/2014] [Accepted: 02/26/2014] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) in combination with cytopathology is the optimal method for diagnosis and staging of pancreatic ductal adenocarcinoma (PDAC) and other pancreatic lesions. Its clinical utility, however, can be limited by high rates of indeterminate or false-negative results. We aimed to develop and validate a microRNA (miRNA)-based test to improve preoperative detection of PDAC. METHODS Levels of miRNAs were analyzed in a centralized clinical laboratory by relative quantitative polymerase chain reaction in 95 formalin-fixed paraffin-embedded specimens and 228 samples collected by EUS-FNA during routine evaluations of patients with solid pancreatic masses at 4 institutions in the United States, 1 in Canada, and 1 in Poland. RESULTS We developed a 5-miRNA expression classifier, consisting of MIR24, MIR130B, MIR135B, MIR148A, and MIR196, that could identify PDAC in well-characterized, formalin-fixed, paraffin-embedded specimens. Detection of PDAC in EUS-FNA samples increased from 78.8% by cytology analysis alone (95% confidence interval, 72.2%-84.5%) to 90.8% when combined with miRNA analysis (95% confidence interval, 85.6%-94.5%). The miRNA classifier correctly identified 22 additional true PDAC cases among 39 samples initially classified as benign, indeterminate, or nondiagnostic by cytology. Cytology and miRNA test results each were associated significantly with PDAC (P < .001), with positive predictive values greater than 99% (95% confidence interval, 96%-100%). CONCLUSIONS We developed and validated a 5-miRNA classifier that can accurately predict which preoperative pancreatic EUS-FNA specimens contain PDAC. This test might aid in the diagnosis of pancreatic cancer by reducing the number of FNAs without a definitive adenocarcinoma diagnosis, thereby reducing the number of repeat EUS-FNA procedures.

Abstract
Background The diagnostic efficiency of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) cytology varies widely depending on the treatment method of the specimens. The present study aimed to evaluate the diagnostic efficacy of cell block (CB) immunohistochemistry, smear cytology (SC), and liquid-based cytology (LBC) in patients with pancreatic lesions without consulting an on-site cytopathologist. Methods This study prospectively enrolled 72 patients with pancreatic lesions. The EUS-FNA specimens were examined by SC, LBC, and CB immunohistochemistry. The diagnostic efficacy of the 3 methods was then compared. Patients’ final diagnosis was confirmed by surgical resection specimens, diagnostic imaging, and clinical follow-up. Results Our results included 60 malignant and 12 benign pancreatic lesions. The diagnostic sensitivity (90%), negative predictive value (66.7%), and accuracy (91.7%) of CB immunohistochemistry were significantly higher than those of SC (70.0%, 30.0%, and 75.0%, respectively) and LBC (73.3%, 31.6%, and 77.8%, respectively) (all P<0.05). The combination of CB and SC, or CB and LBC, did not significantly increase the efficacy compared to CB immunohistochemistry alone. Conclusion Our findings suggest that in the absence of an on-site cytopathologist, CB immunohistochemistry on EUS-FNA specimens offers a higher diagnostic efficacy in patients with pancreatic lesions than does SC and LBC.

Abstract
INTRODUCTION Endoscopic ultrasound (EUS)-guided fine-needle aspiration (FNA) has emerged as a superior method for the diagnosis of pancreatic tumors. Very few large studies have been published. We retrospectively examined 1000 cases to determine the sensitivity and specificity of EUS-guided FNA for solid and cystic lesions. MATERIALS AND METHODS EUS-guided FNA was performed in 1000 patients. Air-dried aspirates were reviewed immediately to ensure adequacy, and ethanol-fixed aspirates were reviewed the following day. The rendered diagnoses were placed into various categories and compared to subsequent histologic and clinical follow-up data. RESULTS Of the 1000 cases, 579 were solid lesions. The FNA diagnoses of the solid lesions were benign (B) 229 (39.5%), atypia (A) 22 (3.8%), suspicious (S) 27 (4.7%), malignant (M) 260 (44.9%), tumor (T) 1 (0.2%), and nondiagnostic (ND) 40 (6.9%). The sensitivity, specificity, positive predictive value, and negative predictive value for solid lesions were 97%, 97%, 99%, and 94%, respectively. There were 421 cystic lesions. The FNAs of the cystic lesions were classified as follows: B 342 (81.2%), A 5 (1.2%), S 4 (1%), M 7 (1.7%), T 46 (10.9%), and ND 17 (4.0%). The sensitivity, specificity, positive predictive value, and negative predictive value to identify mucinous tumors and malignancy for cystic lesions were 46%, 98%, 94%, and 87%, respectively. CONCLUSIONS At our institution, EUS-guided FNA of solid pancreatic lesions is both sensitive and specific for the diagnosis of both primary and metastatic tumors. For cystic lesions, FNA is not as sensitive, but its specificity remains high.

Abstract
AIM To evaluate the safety and efficacy of computed tomography (CT)-guided percutaneous fine-needle aspiration biopsy (FNAB) of pancreatic masses that traverses the gastrointestinal tract or solid viscera. MATERIALS AND METHODS From January 2002 to December 2012, 144 patients underwent 165 CT-guided biopsies of pancreatic masses. Biopsies were performed using a 21 or 22 G needle. Cytology reports, medical records, and procedure details for all patients were retrospectively reviewed to evaluate the biopsy route, complications, and diagnostic accuracy. RESULTS Trans-organ biopsies of pancreatic masses were safely performed via a direct pathway traversing the stomach (n = 45), colon (n = 14), jejunum (n = 4), or liver (n = 5). There were five self-limiting mesenteric haematomas along the biopsy route on immediate post-procedure CT and all patients remained asymptomatic. All haematomas occurred after a trans-mesenteric approach rather than passage through abdominal organs. Three patients had acute pancreatitis. There was no significant difference in complications and diagnostic yields between the groups. The sensitivity, specificity, positive predictive value, and negative predictive value of final FNAB cytology for malignancy were 98.3%, 100%, 100% and 71.4%, respectively. The overall accuracy was 98.4%. CONCLUSION Percutaneous FNAB using the trans-organ approach is a safe and effective technique to diagnose pancreatic malignancy.

Abstract
Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is a technique which allows the study of cells obtained through aspiration in different locations near the gastrointestinal tract. EUS-FNA is used to acquire tissue from mucosal/submucosal tumors, as well as peri-intestinal structures including lymph nodes, pancreas, adrenal gland, gallbladder, bile duct, liver, kidney, lung, etc. The pancreas and lymph nodes are still the most common organs targeted in EUS-FNA. The overall accuracy of EUS is superior to computed tomography scan and magnetic resonance imaging for detecting pancreatic lesions. In most cases it is possible to avoid unnecessary surgical interventions in advanced pancreatic cancer, and EUS is considered the preferred method for loco-regional staging of pancreatic cancer. FNA improved the sensitivity and specificity compared to EUS imaging alone in detection of malignant lymph nodes. The negative predictive value of EUS-FNA is relatively low. The presence of a cytopathologist during EUS-FNA improves the diagnostic yield, decreasing unsatisfactory samples or need for additional passes, and consequently the procedural time. The size of the needle is another factor that could modify the diagnostic accuracy of EUS-FNA. Even though the EUS-FNA technique started in early nineteen's, there are many remarkable progresses culminating nowadays with the discovery and performance of needle-based confocal laser endomicroscopy. Last, but not least, identification and quantification of potential molecular markers for pancreatic cancer on cellular samples obtained by EUS-FNA could be a promising approach for the diagnosis of solid pancreatic masses.

Abstract
Endoscopic ultrasound (EUS) has evolved to become a crucial tool for the evaluation of pancreatic diseases, among them solid pancreatic lesions. However, its ability to determine whether a lesion is malignant or not is difficult to establish based only in the endosonographic image. EUS-guided fine needle aspiration (EUS-FNA) allows obtaining a cytological and/or histological sample from pancreatic lesions, with a high overall accuracy and low complication rates. Although the clinical usefulness of EUS-FNA for pancreatic diseases is widely accepted, the indications for tissue diagnosis of pancreatic lesions suspected to be malignant is still controversial. This review highlights the diagnostic accuracy and complications of EUS-FNA, focusing on its current indications.

Abstract
OBJECTIVE To assess the efficacy and complication rates of percutaneous ultrasound (US)-guided pancreatic mass biopsy and to determine if location of the mass or method of biopsy affects efficacy. METHODS Imaging, pathology, and clinical records of all patients undergoing percutaneous US-guided pancreatic mass sampling from January 2001 until November 2011 were reviewed. Of 88 pancreatic masses, 13 underwent fine needle aspiration (FNA) only, 60 underwent core needle biopsy only, and 15 underwent both. Diagnostic rate, sensitivity, specificity, accuracy, and positive predictive value and negative predictive value (NPV) based on location of the mass (head/neck vs. body/tail) and method of biopsy (core vs. FNA vs. combined) were determined. The final diagnosis was determined on the basis of follow-up imaging, clinical course, and/or surgical pathology. Complications were assessed by reviewing clinical notes and postprocedural imaging. RESULTS The overall diagnostic rate, sensitivity, accuracy, and NPV of all 88 biopsies were 94%, 93%, 93%, and 57%, respectively. Five samples were nondiagnostic and considered false negatives. There were no false-positive biopsy results. No significant difference was observed in the diagnostic rate, sensitivity, accuracy, and NPV between core biopsies, FNAs, and combined core and FNA biopsies. Furthermore, no significant difference was found between head/neck and body/tail samplings. In 96.7% (85/88) of the cases, the procedure was uneventful. There were no major complications. CONCLUSIONS Percutaneous US-guided sampling of pancreatic mass is safe and effective irrespective of location of the mass and method of biopsy.

Abstract
AbstractPancreatic cysts involve a wide spectrum of pathologies from post-inflammatory cysts to malignant neoplasms. Pancreatic pseudocysts, serous cystadenomas, mucinous cystadenomas, intraductal papillary mucinous neoplasms (IPMNs) and solid pseudopapillary tumors occur most frequently. Differential diagnosis involves the following imaging investigations: transabdominal ultrasonography (TUS), contrast enhanced ultrasonography (CEUS) and endoscopic ultrasonography (EUS), computed tomography (CT), magnetic resonance (MR) and magnetic resonance cholangiopancretography (MRCP), endoscopic retrograde cholangiopancretography (ERCP). The cyst fluid cytology is performed in difficult differential diagnosis between pseudocysts and benign and potentially malignant or malignant tumors. Most frequently, viscosity, amylase, CEA and CA 19-9 levels are determined. Imaging findings should be correlated with cytology. The management depends on the cyst type and size. Small asymptomatic pseudocysts, serous cystadenomas and branchduct IPMNs should be carefully observed, whereas symptomatic large or uncertain serous cystadenomas and cystadenocarcinomas, mucinous cystadenomas and cystadenocarcinomas, main-duct IPMNs and large branch-duct IPMNs with malignant features, serous and mucinous cystadenocarcinomas, and solid pseudopapillary tumors require surgery. Pseudocysts are usually drained. Percutaneous / EUS-guided or surgical cyst drainage can be performed. Complicated and uncertain pseudocysts and cystic tumors need surgical resection. The type of surgery depends on cyst location and size and includes proximal, central, distal, total pancreatectomies and enucleation.

Abstract
Pancreatic lesions in young patients are relatively rare and, to our knowledge, the clinical value of pancreatic fine needle aspiration (FNA) in patients < 35 years of age has not been previously established by any other large retrospective studies. All pancreatic endoscopic ultrasound-guided FNA (EUS-FNA) cases performed on patients < 35 years of age were identified for a 17-year period (1994-2010). All FNAs and all available correlating surgical pathology reports were reviewed. There were a total of 174 cases of pancreatic FNA performed on 109 females and 65 males under the age of 35 (range: 8-34, mean: 27 years). The FNA diagnoses included 37 malignant, 114 negative, nine atypia/suspicious, and 14 cases that were nondiagnostic. Of the 37 malignant FNA cases, the diagnoses included 18 pancreatic neuroendocrine tumors (PanNeT), 11 solid pseudopapillary neoplasms (SPN), five adenocarcinomas and three metastatic neoplasms. Histologic follow-up was available in 22 of the 37 malignant cases diagnosed by FNA, and the diagnosis was confirmed in 21 cases. One pancreatoblastoma was misclassified as SPN on EUS-FNA. False negative diagnoses were noted in three cases of low-grade mucinous cystic neoplasm and one case of PanNeT. The most common type of neoplasms diagnosed by EUS-FNA in patients < 35-year old is PanNeT, followed by SPN with both tumors accounting for 75% of all the neoplasms encountered in this age group. The sensitivity and specificity for positive cytology in EUS-FNA of the pancreas to identify malignancy and mucinous neoplasms were 90% and 100%, respectively. Diagn.

Abstract
Pancreatic dermoid cysts are a rare entity. Preoperative diagnosis is difficult. The diagnosis is generally taking intraoperative. A 20-year-old female presented with epigastric pain without nausea, vomiting, diarrhea, fever, jaundice, and weight loss of one-month duration. Ultrasonography and computed tomography showed a smooth borders, solid, hyperechoic tumor within midline abdomen, without any connection to the stomach or spleen. At surgery, the entire mass was excised off of the head and inferior part of pancreas. Histopathologic evaluation revealed the rare diagnosis of a dermoid cyst. The diagnosis is difficult preoperatively in evaluating cystic pancreatic lesions by imaging. Therefore, we want to summarize the literature on this rare entity knowledge.

Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is one of the least invasive and most effective modality in diagnosing pancreatic adenocarcinoma in solid pancreatic lesions, with a higher diagnostic accuracy than cystic tumors. EUS-FNA has been shown to detect tumors less than 3 mm, due to high spatial resolution allowing the detection of very small lesions and vascular invasion, particularly in the pancreatic head and neck, which may not be detected on transverse computed tomography. Furthermore, this minimally invasive procedure is often ideal in the endoscopic procurement of tissue in patients with unresectable tumors. While EUS-FNA has been increasingly used as a diagnostic tool, most studies have collectively looked at all primary pancreatic solid lesions, including lymphomas and pancreatic neuroendocrine neoplasms, whereas very few studies have examined the diagnostic utility of EUS-FNA of pancreatic ductal carcinoma only. As with any novel and advanced endoscopic procedure that may incorporate several practices and approaches, endoscopists have adopted diverse techniques to improve the tissue procurement practice and increase diagnostic accuracy. In this article, we present a review of literature to date and discuss currently practiced EUS-FNA technique, including indications, technical details, equipment, patient selection, and diagnostic accuracy.

Abstract
Pancreatic cancer is the fourth leading cause of cancer mortality for both men and women in the United States. Overall 5-year survival from time of diagnosis is less than 5%. The only meaningful chance for cure results from early detection while the tumor remains resectable without locoregional extension or metastasis. Endoscopic ultrasound (EUS) is uniquely suited to the examination and treatment of the pancreas. Endoscopic ultrasound can provide important information with regard to disease stage including involvement of the mesenteric vasculature, adjacent organ invasion, and regional lymph node metastasis. In addition, EUS is considered the procedure of choice for tissue diagnosis of pancreatic cancer. More recently, EUS has developed therapeutic roles in an array of other clinical situations including EUS-guided fine needle injection, EUS-guided biliary drainage, celiac plexus neurolysis, brachytherapy, fiducial placement, and emerging antitumor agents delivered directly into the tumor.

Diagnostic ability and factors affecting accuracy of endoscopic ultrasound-guided fine needle aspiration for pancreatic solid lesions: Japanese large single center experience. J Gastroenterol 2013; 48:973-81.

Abstract
BACKGROUND Several studies have investigated the diagnostic accuracy of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) for pancreatic lesions, but they have included only limited patient populations. This study aimed to clarify the diagnostic accuracy of EUS-FNA in a large number of pancreatic lesions, and to describe the factors that influence it. METHODS From March 1997 to May 2010, 944 consecutive patients who had undergone EUS-FNA for pancreatic solid lesions were evaluated retrospectively. Factors affecting EUS-FNA accuracy were then analyzed. RESULTS A total of 996 solid pancreatic lesions were sampled by EUS-FNA. The overall sampling adequacy and diagnostic accuracy of these lesions were 99.3 % (989/996) and 91.8 % (918/996), respectively. The sensitivity and specificity for differentiating malignant from benign lesions were 91.5 % (793/867) and 97.7 % (126/129), respectively. The diagnostic performance was significantly higher when both cytological and cell-block examinations were carried out than with only cytological examination. In multivariate analysis, final diagnosis, location of lesion, lesion size, availability of on-site cytopathological evaluation, and experience of EUS-FNA procedure were independent factors affecting the accuracy of EUS-FNA. On-site cytopathological evaluation and lesion size were found to be the most weighted factors affecting diagnostic accuracy. CONCLUSIONS EUS-FNA for pancreatic solid lesions yielded a high accuracy and low complication rate. Both cytological and cell-block preparations and on-site cytopathological evaluation contributed to improve the accuracy. The diagnostic ability of EUS-FNA was less for smaller lesions, and repeated procedures may be needed if malignancy is suspected.

Abstract
The field of diagnostic and therapeutic endoscopic ultrasound (EUS) is growing rapidly. Although EUS has enhanced our ability to diagnose and treat a wide variety of GI conditions, there are many controversial issues regarding the appropriate application of EUS techniques. In this review we discuss five controversial topics in EUS: the utility of EUS in staging of esophageal and gastric cancer; selection of appropriate needle gauge for fine needle aspiration (FNA); use of the stylet in FNA; and the emerging role of contrast agents in endoscopic ultrasound.

Abstract
BACKGROUND Cytological examination of pancreatic juice obtained during endoscopic retrograde cholangiopancreatography (ERCP) is well established, but its sensitivity for pancreatic cancer has not been satisfactory. The aim of this study was to evaluate the usefulness of repeated pancreatic juice cytology (PJC) via the endoscopic naso-pancreatic drainage (ENPD) tube in patients with pancreatic cancer compared with conventional PJC. METHODS We retrospectively investigated 139 patients with pancreatic disease. Between April 2004 and November 2007, conventional PJC was performed in 56 patients with pancreatic cancer and 23 with benign pancreatic stricture. Between January 2008 and November 2010, ENPD was used in 40 patients with pancreatic cancer and 20 with benign pancreatic stricture. The ENPD tube was placed into the main pancreatic duct for up to 3 days, and cytological samples of pancreatic juice were collected up to 6 times in total. RESULTS Sensitivity, specificity, positive predictive value, negative predictive value, and overall accuracy of the ENPD method for pancreatic cancer were 80, 100, 100, 71, and 87 %, respectively, revealing significantly higher sensitivity than the conventional method (p = 0.0001). Sensitivities according to tumor location and size were 90 % (19/21), 69 % (9/13), and 67 % (4/6) in the head, body, and tail of the pancreas, 88 % (7/8), 79 % (19/24), and 75 % (6/8) in tumors with a diameter less than 20 mm including carcinoma in situ, 21-40, and greater than 41 mm, respectively. CONCLUSIONS The ENPD method was found to have high diagnostic yield, especially for tumors less than 20 mm or located in the pancreatic head, and might be useful for the diagnosis of early-stage pancreatic cancer.

Abstract
The role of endoscopic ultrasound (EUS) in the diagnosis of biliary obstruction is well established, and emerging evidence suggests it may also play a therapeutic role. Differentiating between benign and malignant causes of biliary obstruction can be challenging, but EUS is a crucial tool in the armamentarium of the physician. Evolving technologies such as elastography and contrast enhancement may further supplement the diagnostic abilities of EUS. Therapeutic applications of EUS are evolving rapidly, and EUS-guided cholangiography may aid biliary decompression when endoscopic retrograde cholangiopancreatography (ERCP) has failed or is not possible.

Abstract
GOALS To examine the benefits and feasibility of endoscopic ultrasonography (EUS) and endoscopic retrograde cholangiopancreatography (ERCP) in tandem for distal obstructive jaundice. MATERIALS AND METHODS From September 2007 to August 2012, patients with suspected distal obstructive jaundice were randomized to single-session EUS-ERCP (group A), EUS, and ERCP in different sessions (group B), and an ERCP-only procedure (group C). Data were prospectively collected on the following parameters: ERCP-avoided, duration of procedure, the dose of propofol, complications, and diagnostic yield. RESULTS A total of 180 patients were divided randomly into 60 patients in group A, 60 in group B, and 60 in group C. A total of four therapeutic ERCP were canceled after EUS. The ERCP procedural time in group A was shorter, although not significantly different from that in group B (group A vs. group B: 41.24±7.57 vs. 43.38±6.57 min; P>0.05), but both were significantly less than that in group C (group C: 49.12±7.46 min; P<0.05). The total procedural time did not differ significantly between group A and group B (70.05±15.35 vs. 73.70±15.12 min; P>0.05), nor were there significant differences in the dose of propofol between them (group A vs. group B: 357.11±115.86 vs. 369.55±133.86 mg; P>0.05). In all, 22 anesthetic complications and 21 endoscopic complications occurred without significant differences among the three groups (P>0.05). CONCLUSION As a triaging or a screening tool, diagnostic EUS gives added benefit to therapeutic ERCP. EUS and ERCP in a tandem approach are safe and feasible in patients with suspected distal obstructive jaundice.

Abstract
BACKGROUND Endoscopic ultrasound (EUS) with fine-needle aspiration (FNA) is often used to assist in the evaluation of pancreatic lesions and may help to diagnose benign versus malignant neoplasms. However, there is a paucity of literature regarding comparative EUS characteristics of various malignant pancreatic neoplasms (primary and metastatic). OBJECTIVE To compare and characterize primary pancreatic adenocarcinoma versus other malignant neoplasms, hereafter referred to as nonprimary pancreatic adenocarcinoma (NPPA), diagnosed by EUS-guided FNA. METHODS The present study was a retrospective analysis of a prospectively maintained database. The setting was a tertiary care, academic medical centre. Patients referred for suspected pancreatic neoplasms were evaluated. Based on EUS-FNA characteristics, primary pancreatic adenocarcinoma was differentiated from other malignant neoplasms. The subset of other neoplasms was defined as malignant lesions that were 'NPPAs' (ie, predominantly solid or solid⁄cystic based on EUS appearance and primary malignant lesions or metastatic lesions to the pancreas). Pancreatic masses that were benign cystic lesions (pseudocyst, simple cyst, serous cystadenoma) and focal inflammatory lesions (acute, chronic and autoimmune pancreatitis) were excluded. RESULTS A total of 230 patients were evaluated using EUS-FNA for suspected pancreatic mass lesions. Thirty-eight patients were excluded because they were diagnosed with inflammatory lesions or had purely benign cysts. One hundred ninety-two patients had confirmed malignant pancreatic neoplasms (ie, pancreatic adenocarcinoma [n=144], NPPA [n=48]). When comparing adenocarcinoma with NPPA lesions, there was no significant difference in mean age (P=0.0675), sex (P=0.3595) or average lesion size (P=0.3801). On average, four FNA passes were necessary to establish a cytological diagnosis in both lesion subtypes (P=0.396). Adenocarcinomas were more likely to be located in the pancreatic head (P=0.0198), whereas masses in the tail were more likely to be NPPAs (P=0.0006). Adenocarcinomas were also more likely to exhibit vascular invasion (OR 4.37; P=0.0011), malignant lymphadenopathy (P=0.0006), pancreatic duct dilation (OR 2.4; P=0.022) and common bile duct dilation (OR 2.87; P=0.039). CONCLUSIONS Adenocarcinoma was more likely to be present in the head of the pancreas, have lymph node and vascular involvement, as well as evidence of pancreatic duct and common bile duct obstruction. Of all malignant pancreatic lesions analyzed by EUS-FNA, 25% were NPPA, suggesting that FNA is crucial in establishing a diagnosis and may be helpful in preoperative planning.

Abstract
BACKGROUND Endoscopic ultrasound-guided fine-needle aspiration biopsy (EUS-FNA) can be coupled with endoscopic retrograde cholangiopancreatography in the same setting when biliary and/or duodenal stenting are required. AIMS Our aim was to examine the effectiveness of EUS-FNA combined with stenting during the same session in patients with pancreatic cancer. METHODS Consecutive patients referred for EUS-FNA of a pancreatic mass with symptoms of biliary (±upper digestive) obstruction were included. Consecutive patients undergoing biliary and/or duodenal stenting without EUS-FNA during the same period were used as controls. Procedure-related complications were the primary outcome measure. Duration of the procedure, ability to achieve biliary/duodenal stenting, the yield of EUS-FNA, and clinical outcomes were evaluated. RESULTS A total of 122 patients underwent combined EUS-FNA and stenting and 68 underwent stenting alone (control group). In the combined group, histological proof of cancer was obtained in 88.52% at first EUS-FNA and 95.08% after a second EUS-FNA. Biliary stent placement was successful in 97.5 and 98% in the combined and the control groups, respectively. There was no statistical difference between the groups for length of stay after endoscopy and for procedure-related mortality and morbidity within 30 days. The median time from endoscopy to chemotherapy in the combined group was 12 days. CONCLUSION Combined EUS-FNA and biliary and/or duodenal stenting is feasible in almost all patients with suspected pancreatic cancer, with no additional hazard and a high histological yield.

Abstract
Endoscopic ultrasonography (EUS) has gained wide acceptance as an important, minimally invasive diagnostic tool in gastroenterology, pulmonology, visceral surgery and oncology. This review focuses on data regarding risks and complications of non-interventional diagnostic EUS and EUS-guided fine-needle biopsy (EUS-FNB). Measures to improve the safety of EUS und EUS-FNB will be discussed. Due to the specific mechanical properties of echoendoscopes in EUS, there is a low but noteworthy risk of perforation. To minimize this risk, endoscopists should be familiar with the specific features of their equipment and their patients’ specific anatomical situations (e.g., tumor stenosis, diverticula). Most diagnostic EUS complications occur during EUS-FNB. Pain, acute pancreatitis, infection and bleeding are the primary adverse effects, occurring in 1% to 2% of patients. Only a few cases of needle tract seeding and peritoneal dissemination have been reported. The mortality associated with EUS and EUS-FNB is 0.02%. The risks associated with EUS-FNB are affected by endoscopist experience and target lesion. EUS-FNB of cystic lesions is associated with an increased risk of infection and hemorrhage. Peri-interventional antibiotics are recommended to prevent cyst infection. Adequate education and training, as well consideration of contraindications, are essential to minimize the risks of EUS and EUS-FNB. Restricting EUS-FNB only to patients in whom the cytopathological results may be expected to change the course of management is the best way of reducing the number of complications.

Abstract
BACKGROUND/AIMS EUS elastography is a novel technique that can be used for distinguishing benign from malignant lymph nodes and focal pancreatic masses. However, the studies pertaining to EUS elastography for differential diagnosis of solid pancreatic masses have reported widely varied sensitivities and specificities. A meta-analysis of all relevant articles was performed to estimate the overall diagnostic accuracy of EUS elastography for differentiating benign and malignant solid pancreatic masses. METHODS The literatures were identified by searching in PubMed and Embase databases. Two reviewers independently extracted the information from the literatures for constructing 2 × 2 table. A random-effect model or a fixed-effect model was used to estimate the sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and diagnostic odds ratio. A summary receiver operating characteristic curve (SROC) also was constructed. Meta-regression and subgroup analysis were used to explore the sources of heterogeneity. RESULTS 13 studies including a total of 1042 patients with solid pancreatic masses were selected for meta-analysis. The pooled sensitivity and specificity of EUS elastography for differentiating benign and malignant solid pancreatic masses were 95% (95% confidence interval [CI], 93%-96%), 69% (95% CI, 63%-75%), respectively. The area under SROC (AUC) was 0.8695. Two significant variables were associated with heterogeneity: color pattern and blinding. CONCLUSION As a less invasive modality, EUS elastography is a promising method for differentiating benign and malignant solid pancreatic masses with a high sensitivity, and it can prove to be a valuable supplement to EUS-FNA.

Abstract
OBJECTIVE To summarize EUS-FNA test performance in suspected pancreatic malignancy with meta-analysis. METHOD Two reviewers searched MEDLINE (PubMed and Ovid from January 2002 to January 2012) database to identify relevant studies. The reference lists of the trials were manually searched. Included studies used histopathology or clinical and morphological (CT and MRI and US) follow-up as the "gold standard" and provided sufficient data to construct a diagnostic 2 × 2 table. A statistical program of Meta-Disc was used to calculate the pooled sensitivity, specificity, positive LR, negative LR, DOR, and the SROC curve. Subgroup analysis and meta-regression were calculated to evaluate potential sources of heterogeneity. RESULT A total of 15 studies with 1860 patients were included for the analysis. The pooled sensitivity and specificity of EUS-FNA were 92 % (95 % CI = 91-93 %, p < 0.001, I (2) = 69.6 %) and 96 % (95 % CI = 93-98 %, p = 0.006, I (2) = 54.9 %), respectively. The positive LR and negative LR were 14.24 (95 % CI = 7.78-26.07) and 0.09 (95 % CI = 0.07-0.13), respectively. The area under the curve was 0.974. The subgroup analysis of six studies with rapid on-site evaluation (ROSE) showed a pooled sensitivity of 95 % (95 % CI = 93-96 %), with p value equal 0.622 and I (2) = 0. The sensitivity analysis of ten high-quality studies (a score of ≥4) showed a pooled sensitivity of 94 % (95 % CI = 93-96 %, p = 0.144, I (2) = 33.1 %), and the pooled specificity was 0.95 (95 % CI, 0.91-0.97). CONCLUSION EUS-FNA had overall excellent specificity and sensitivity in accurately diagnosing solid pancreatic masses. ROSE could help to improve the accuracy of diagnostic test.

Abstract
BACKGROUND & AIMS Histologic techniques are used to distinguish autoimmune pancreatitis (AIP) from pancreatic malignancies and to confirm the etiology of pancreatitis. Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is a well-established technique used in the diagnosis of pancreatic cancer. However, it is unclear whether specimens obtained from pancreatic lesions by EUS-FNA are adequate for the histologic diagnosis of AIP, because the evaluation of tissue architecture and immunostaining assays usually require larger samples. METHODS We evaluated samples collected by EUS-FNA with a conventional 19-gauge needle by histologic analysis, looking for features of AIP. We analyzed data from 44 patients who were diagnosed with AIP and underwent EUS-FNA with a 19-gauge needle from January 2004 to September 2010. The FNA specimens were reviewed by histologic analysis; AIP was diagnosed based on the presence of lymphoplasmacytic sclerosing pancreatitis or immunoglobulin (Ig)G4-positive plasma cells in the infiltrate. RESULTS The specimen amount was inadequate from 3 patients. Among the remaining 41 patients, histopathologic analysis revealed lymphoplasmacytic sclerosing pancreatitis in 17 samples and IgG4-positive plasma cells in 5 (3 samples were positive for both); no samples had granulocytic epithelial lesions. Therefore, 19 patients (43%) were diagnosed with AIP based on histologic analysis. One patient had temporary abdominal pain. CONCLUSIONS EUS-FNA, with a 19-gauge needle, is a safe and reliable procedure for obtaining pancreatic samples for the histologic analysis of AIP. Although it does not have a high diagnostic yield, it might be useful in patients without typical features of AIP because it would allow patients to avoid surgery.

Abstract
BACKGROUND/AIM Endosonography is a distinct method for evaluating the structural lesions of the gastrointestinal (GI) tract, particularly the pancreatobilliary region. This procedure has made a fundamental change in the diagnosis of pancreatic mass lesion through providing fine needle aspiration. This study aims at evaluating the results and efficacy of endoscopic ultrasound fine needle aspiration (EUS-FNA) in patients with pancreatic solid mass. PATIENTS AND METHODS The present study is an observational, prospective case series nature, evaluated patients with pancreatic solid mass referred to Imam Khomeini educational hospital in Tehran for a duration of one year since November 2010. In order to determine the false negative cases, the patients were followed-up from 6 to 12 months. RESULTS EUS-FNA was conducted on all 53 patients without any complication. The majority of patients included in the study were males (68%) and 81% of patients had a mass in the head of pancreas. The result of cytopathology revealed 36 adenocarcinomas (68%), 7 other malignancies (13%), benign lesions (6%) and 7 non-diagnostic cases (13%). The frequency of non-diagnostic results was significantly high in masses smaller than 3 cm (6 vs. 1, P < 0.002). Patients with non-diagnostic result were younger than those with malignant cytopathology (52 ± 7.5 vs. 66 ± 7.5 years, P < 0.001).. Sensitivity, specificity, positive predictive value, negative predictive value and accuracy of this procedure concerning Adenocarcinoma were 88%, 100%, 100%, 70% and 90%, respectively. CONCLUSION EUS - FNA is an effective and safe procedure in histopathologic diagnosis of pancreatic tumors. This procedure is useful in all pancreatic mass cases including resectable and non-resectable ones.

Abstract
The diagnosis and treatment of patients with pancreatic strictures presents a multitude of clinical challenges. The etiology of pancreatic strictures is varied, including benign strictures subsequent to acute pancreatitis, trauma, postsurgical, post-endoscopic retrograde cholangiopancreatography (ERCP), and malignancy. Patients with strictures usually present with symptoms of recurrent pancreatitis, abdominal pain, weight loss, and/or steatorrhea. The absence of a prior history of pancreatitis or surgery increases the likelihood of malignancy. High-quality imaging studies of the pancreas, CT, MRI/magnetic resonance cholangiopancreatography, or endoscopic ultrasound (EUS) scanning are utilized for better definition. Imaging detects an associated mass and/or demonstrates the ductal anatomy. Invasive procedures such as ERCP are performed to better define the causal relationships of the patient's symptoms or to obtain tissue diagnosis. Treatment goals include ameliorating symptoms, dilating the stricture, and ruling out cancer. The risk of malignancy underlies much of the intervention, which includes serology, cytologic analysis, and serial imaging. EUS has become the procedure of choice to rule out a mass, to evaluate the parenchyma for evidence of chronic pancreatitis, and to obtain fine-needle biopsies for tissue confirmation. In symptomatic patients or patients with indeterminate strictures, ERCP is used for direct pancreatography, tissue acquisition, and endoscopic treatment. Endotherapy includes sphincterotomy, dilation, and stenting to provide drainage. We view ERCP as the optimal first-line treatment modality. ERCP offers the potential of curative treatment and is less invasive than surgery, especially as some patients' symptoms are not severe enough to justify surgery. If patients do not experience relief of symptoms after several sessions of endoscopic therapy, surgery is the logical next step for definitive, long-term treatment.

Abstract
PURPOSE The present study aimed to explore the safety profile and clinical efficacy of CT-guided radioactive seed implantation in treating local recurrent rectal carcinoma. MATERIALS AND METHODS CT-guided ¹²⁵I seed implantation was carried out in 20 patients with locally recurrent rectal carcinoma. 14 of the 20 patient had prior adjuvant external-beam radiation therapy (EBRT). The treatment planning system (TPS) was used preoperatively to reconstruct three dimensional images of the tumor and to calculate the estimated seed number and distribution. The median matched peripheral dose (MPD) was 120 Gy (range, 100-160 Gy). RESULTS Of the 20 patients, 12 were male, 8 were female, and ages ranged from 38 to 78, with a median age of 62. Duration of follow-up was 3-34 months. The response rate of pain relief was 85% (17/20). Repeat CT scan 2 months following the procedure revealed complete response (CR) of the tumor in 2 patients, partial response (PR) in 13 patients, stable disease (SD) in 3 patients, and progressive disease (PD) in 2 patients. 75% of patients had either CR or PR. Median survival time was 18.8 months (95% CI: 3.5-22.4 months). 1 and 2 year survival rates were 75% and 25%, respectively. 4 patients died of recurrent tumor; 4 patients died of distant metastases; 9 patients died of recurrent tumor and distant metastases. 3 patients survived after 2 year follow up. Two patients were found to have mild hematochezia, which was reversible with symptomatic management. CONCLUSION CT-guided ¹²⁵I seed implantation appeared to be a safe, useful and less complicated interventional treatment option for local recurrent rectal carcinoma.

Abstract
BACKGROUND AND AIM Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is an accurate method for cytological confirmation of pancreatic malignancy, but it has been unknown whether its diagnostic accuracy for pancreatic lesions was affected by their size, location, or size of needles. Our aim was to investigate the accuracy of EUS-FNA for suspected pancreatic malignancy in relation to these factors, especially to the size of lesions. METHODS In a tertiary referral center, EUS-FNAs for 120 suspected pancreatic malignancies in 115 patients based on other imaging studies were evaluated retrospectively. RESULTS Overall accuracy of EUS-FNA was 96% (115/120), with sensitivity of 95% (76/80), specificity of 98% (39/40), positive predictive value of 99% (76/77), and negative predictive value of 91% (39/43). Accuracies for lesions less than 10mm, 11-20mm, 21-30mm, and more than 31mm were 96%, 95%, 96%, and 100%, respectively; those for lesions in the head, the body, and the tail of the pancreas were 96%, 95%, and 95%, respectively. Accuracies for 22-gauge and 25-gauge needle were 93% and 98%, respectively. CONCLUSION EUS-FNA was accurate in the evaluation of suspected pancreatic malignancy regardless of its size, location, or size of needles. It was useful also in the confirmation of small pancreatic malignancies less than 10mm.

Screening for pancreatic cancer in a high-risk population with serum CA 19-9 and targeted EUS: a feasibility study. Gastrointest Endosc 2011; 74:87-95. [PMID: 21704809 DOI: 10.1016/j.gie.2011.03.1235] [Citation(s) in RCA: 59] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/15/2010] [Accepted: 03/21/2011] [Indexed: 02/07/2023]
Abstract
BACKGROUND Earlier detection of pancreatic adenocarcinoma is needed. OBJECTIVE To determine whether early pancreatic neoplasia can be detected in a high-risk population by using CA 19-9 followed by targeted EUS. DESIGN Prospective cohort study. SETTING Two academic medical centers. PATIENTS Eligible patients met age criteria and had at least 1 first-degree relative with pancreatic adenocarcinoma. INTERVENTIONS A serum CA 19-9 was performed on all patients. EUS was performed if the CA 19-9 level was elevated. FNA of identified lesions was performed. Patients with pancreatic cancer detected by using this screening protocol were compared with patients presenting off-protocol for staging data. Medicare reimbursement rates were used to derive cost data. MAIN OUTCOME MEASUREMENTS Detection of early pancreatic neoplasia. RESULTS A total of 546 patients were enrolled. CA 19-9 was elevated in 27 patients (4.9%, 95% CI, 3.2%-7.1%). Neoplastic or malignant findings were detected in 5 patients (0.9%, 95% CI, 0.3%-2.1%), and pancreatic adenocarcinoma in 1 patient (0.2%, 95% CI, 0.005%-1.02%). The patient with pancreatic cancer detected as part of this protocol was 1 of 2 patients presenting to the University of Vermont with stage 1 cancer. The cost to detect 1 pancreatic neoplasia was $8431. The cost to detect 1 pancreatic adenocarcinoma was $41,133. LIMITATIONS The sample size is adequate only to demonstrate the feasibility of this approach. CONCLUSIONS Potentially curative pancreatic adenocarcinoma can be identified with this screening protocol. Stage 1 pancreatic cancer is more likely to be detected by using this screening protocol than by using standard means of detection.

Abstract
Pancreatic cancer is one of the most deadly solid tumors, with an overall 5-year survival rate of less than 5%. Due to a non-specific clinical presentation, it is often diagnosed at an advanced stage and is rarely amenable for curative treatment. Therefore early diagnosis and appropriate staging are still essential to define the best care and to improve patient survival. Several imaging modalities are currently available for the evaluation of pancreatic cancer. This review focuses on different techniques and discusses the diagnostic management of patients with pancreatic cancer. This review was conducted utilizing Pubmed and was limited to papers published within the last 5 years. The search key words pancreatic cancer, pancreatic adenocarcinoma, pancreatic tumors, diagnosis, radiology, imaging, nuclear imaging, endoscopy, endoscopic ultrasound and biochemical markers were used.
