Abstract
Pain in pancreatic cancer is often a major problem of treatment. Administration of opioids is frequently limited by side effects or insufficient analgesia. Endoscopic ultrasound-guided celiac plexus neurolysis (EUS-CPN) represents an alternative for the palliative treatment of visceral pain in patients with pancreatic cancer. This review focuses on the indications, technique, outcomes of EUS-CPN and predictors of pain relief. EUS-CPN should be considered as the adjunct method to standard pain management. It moderately reduces pain in pancreatic cancer, without eliminating it. Nearly all patients need to continue opioid use, often at a constant dose. The effect on quality of life is controversial and survival is not influenced. The approach could be done in the central position of the celiac axis, which is easy to perform, or in the bilateral position of the celiac axis, with similar results in terms of pain alleviation. The EUS-CPN with multiple intraganglia injection approach seems to have better results, although extended studies are still needed. Further trials are required to enable more confident conclusions regarding timing, quantity of alcohol injected and the method of choice. Severe complications have rarely been reported, and great care should be taken in choosing the site of alcohol injection.

Abstract
Palpation is a subjective and non-sharable diagnostic method. Recently, palpation has been supported and replaced by elastography, which provides a novel parameter of “stiffness” as a visual representation or quantified value. Today, elastography is performed using two major modalities: strain elastography and shear wave elastography. Strain elastography converts the extent of deformation during external compression into colors, displaying these colors as a strain map in a motion picture representing the relative elasticity inside the region of interest. Shear wave elastography can quantify the elasticity of a target by calculating the velocity of shear waves generated by a probe. In addition to superficial organs, elastography has also been applied to upper abdominal organs, including the liver, pancreas and spleen. The visualization of the stiffness of focal lesions in the liver or the pancreas has enabled a more sensitive and specific depiction of small, non-palpable nodules, which are difficult to depict using B-mode ultrasonography. The quantification of stiffness also enables non-invasive estimates of liver fibrosis, the risk of postoperative liver insufficiency and the risk of recurrence of viral hepatitis after transplantation. In this article, we review the major reports that have recently been published describing the effective application of elastography to solid upper abdominal organs in a clinical setting.

Interventional endoscopic ultrasonography: an overview of safety and complications. Surg Endosc 2013; 28:712-34. [PMID: 24196551 DOI: 10.1007/s00464-013-3260-5] [Citation(s) in RCA: 54] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2013] [Accepted: 09/27/2013] [Indexed: 02/06/2023]
Abstract
BACKGROUND In recent years, endoscopic ultrasonography (EUS)-guided techniques have been developed as alternatives to surgical, radiologic, or conventional endoscopic approaches for the treatment or palliation of several digestive diseases. The use of EUS guidance allows the therapeutic area to be targeting more precisely, with a possible clinical benefit and less morbidity. Nevertheless, the risks persist and must be taken into consideration. This review gives an overview of the complications observed with the most established procedures of therapeutic EUS. METHODS The PubMed and Embase databases were used to search English language articles on interventional EUS. The studies considered for inclusion were those reporting on complications of EUS-guided celiac plexus block (EUS-CPB), EUS-guided celiac plexus neurolysis (EUS-CPN), drainage of fluid pancreatic and pelvic collections, and EUS-guided biliary and pancreatic drainage (EUS-BD and EUS-PD). Variations in methodology and design in most studies made a thorough statistical analysis difficult. Instead, a frequency analysis of complications and a critical discussion were performed. RESULTS Although EUS-guided celiac plexus injection causes mainly mild and transient complications, growing experience shows that EUS-CPN is not as benign a procedure as previously thought. Most of the major complications have been observed in patients with chronic pancreatitis. The findings show that EUS-guided drainage of fluid collections is a safe procedure. Complications occur more often after the drainage of pancreatic abscesses and necrosis. Although the heterogeneity of studies dealing with pancreatobiliary drainage makes the evaluation of risks after these procedures difficult, complications after EUS-BD and EUS-PD are relatively frequent and can be severe. The technical complexity and the lack of specifically designed devices may account for their complication rates. CONCLUSIONS Clinicians can consider EUS-guided celiac injection and EUS-guided drainage of fluid collections to be safe alternatives to surgical and radiologic interventions. Well-designed prospective trials are needed to assess the risks of EUS-BD and EUS-PD accurately before they are broadly advocated after a failed endoscopic retrograde cholangiopancreatography (ERCP).

Abstract
Background/Aims Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is useful for the pathological diagnosis of pancreatic masses, but patients are susceptible to severe bleeding and perforation. Because the incidence and severity of these complications have not been fully evaluated. Methods We aimed to evaluate severe bleeding and perforation after EUS-FNA for pancreatic masses using large-scale data derived from a Japanese nationwide administrative database. Results In total, 3,090 consecutive patients from 212 low- to high-volume hospitals were analyzed. Severe bleeding requiring transfusion or endoscopic treatment occurred in seven patients (0.23%), and no perforation was observed. No patient mortality was recorded within 30 days of EUS-FNA. The rate of severe bleeding in low-volume hospitals was significantly higher than that in medium- and high-volume hospitals (0.48% vs 0.10%, p=0.045). Conclusions Severe bleeding and perforation following EUS-FNA for pancreatic masses are rare, and the procedure is safe.

Abstract
Endoscopic ultrasound (EUS) can help diagnose diseases with high accuracy because it overcomes the limitations of gastrointestinal gas and abdominal fat. The emergence of curved linear-array echoendoscopy has significantly promoted the applications of the technique to new levels. The advancement has appeared from EUS imaging to EUS-guided fine needle aspiration, drainage and injection. Computed tomography and magnetic resonance imaging present certain limitations for diagnosing pancreatic tumors due to the specificity of the location of such growths. In addition, traditional chemotherapy does not show ideal results because pancreatic cancer (PC) exhibits hypovascular characteristics. Interventional EUS can overcome these limitations and has potential to become the mainstream method of PC local treatment in the future. This paper reviews the use of interventional EUS in the treatment of PC based on previous studies.

Abstract
Endoscopic management of symptomatic pancreatic fluid collections (PFCs) is now considered to be first line therapy. Expanded use of endoscopic ultrasound (EUS) techniques has resulted in increased applicability, safety, and efficacy of endoscopic transluminal PFC drainage. Steps include EUS-guided trangastric or transduodenal fistula creation into the PFC followed by stent placement or nasocystic drain deployment in order to decompress the collection. With the remarkable improvement in the available accessories and stents and development of exchange free access device; EUS drainage techniques have become simpler and less time consuming. The use of self-expandable metal stents with modifications to drain PFC has helped in overcoming some previously encountered challenges. PFCs considered suitable for endoscopic drainage include collection present for greater than 4 weeks, possessing a well-formed wall, position accessible endoscopically and located within 1 cm of the duodenal or gastric walls. Indications for EUS-guided drainage have been increasing which include unusual location of the collection, small window of entry, nonbulging collections, coagulopathy, intervening varices, failed conventional transmural drainage, indeterminate adherence of PFC to the luminal wall or suspicion of malignancy. In this article, we present a review of literature to date and discuss the recent developments in EUS-guided PFC drainage.

Abstract
BACKGROUND Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is an established procedure for the pathological diagnosis of gastrointestinal submucosal tumors (SMTs). Although bleeding and perforation are potentially severe complications of EUS-FNA, the incidences and severities of these complications have not yet been fully evaluated because of their relative rarity. AIM The purpose of this study was to evaluate the incidences and mortality of severe bleeding and perforation in patients who underwent EUS-FNA for SMTs. METHODS The records of 1,135 consecutive patients who underwent EUS-FNA for SMTs at 219 hospitals, with low- to high-volume, were reviewed using a Japanese nationwide administrative database. RESULTS Of the targeted lesions 73.5% were located in the stomach, 13.4% in the esophagus, 8.2% in the duodenum, and 4.9% at other sites. Five patients (0.44%) experienced severe bleeding requiring red blood cell transfusion or endoscopic treatment, with none experiencing perforation. Only one patient (0.09%) died in-hospital within 30 days of EUS-FNA (0.09%), with death not associated with bleeding or perforation. CONCLUSIONS EUS-FNA is safe in evaluating SMTs, with low risks of bleeding and perforation.

Abstract
OBJECTIVE This systematic review assesses the effectiveness and side effects of celiac plexus neurolysis (CPN) in the treatment of upper abdominal cancer pain, and evaluates whether there are any differences between the percutaneous and endoscopic ultrasound-guided (EUS) denervation techniques. METHODS Five databases were searched, expanded by assessing the reference lists of all retrieved papers. Sixty-six publications fulfilled the inclusion/exclusion criteria and were included in the systematic review. Randomized controlled trials were available for the percutaneous CPN, and therefore meta-analyses were performed for pain, opioid consumption, and specific side effects. The quality of life data were too heterogeneous to be assessed by a meta-analysis, and evidence for EUS CPN could only be evaluated by observational studies. RESULTS Meta-analyses show that percutaneous CPN significantly improves pain in patients with upper abdominal cancer, with a decrease in opioid consumption and side effects. It is unclear whether there is any change in quality of life. Case series suggest that EUS CPN improves pain. No conclusion can be made about EUS CPN's influence on opioid consumption. Although CPN is a safe procedure, side effects and complications can occur with both the percutaneous and EUS techniques. CONCLUSIONS Following this review, evidence suggests that CPN should be considered in patients with upper abdominal cancer where the pain is not adequately controlled with systemic analgesics or when significant opioid-induced side effects are present. The percutaneous approach remains the standard technique as robust evidence for EUS CPN is lacking.

Abstract
A suspected pancreatic lesion can be a difficult challenge for the clinician. In the last years we have witnessed tumultuous technological improvements of the radiological and nuclear medicine imaging. Taking this into account, we will try to delineate the new role of endoscopic ultrasound (EUS) in pancreatic imaging and to place it in a shareable diagnostic and staging algorithm of pancreatic cancer (PC). To date the most accurate imaging techniques for the PC remain contrast-enhanced computed tomography (CT) and EUS. The latter has the highest accuracy in detecting small lesions, in assessing tumor size and lymph nodes involvement, but helical CT or an up-to-date magnetic resonance imaging (MRI) must be the first choice in patients with a suspected pancreatic lesion. After this first step there is place for EUS as a second diagnostic level in several cases: negative results on CT/MRI scans and persistent strong clinical suspicion of PC, doubtful results on CT/MRI scans or need for cyto-histological confirmation. In the near future there will be great opportunities for the development of diagnostic and therapeutic EUS and pancreatic pathology could be the best testing bench.

Abstract
OBJECTIVES Endoscopic ultrasonography-guided fine needle aspiration (EUS-FNA) is widely performed for pancreatic masses. The 25-gauge needle (25G) might be easier to be manipulated and expected to be associated with fewer complications since it is thinner and more flexible than the 22-gauge needle (22G) although obtaining adequate specimens is questioned. In this randomized trial, the authors tried to compare prospectively 25G and 22G in diagnostic accuracy, manipulability from the operator's viewpoint and procedure-related complications. MATERIAL AND METHODS A total of 188 consecutive patients undergoing EUS-FNA for solid or cystic pancreatic masses were consecutively enrolled and 94 patients were randomized to either 25G or 22G group, respectively. RESULTS Baseline characteristics were similar except that more masses of 25G group were located in the head or uncinate process of pancreas than those from 22G group. Although there was no difference in diagnostic accuracy (89.4% vs. 88.3% with p = 0.82), 25G was easier to be manipulated (p = 0.004) and related with fewer procedure-related complications (10.6% vs. 3.2% with p = 0.004). CONCLUSIONS 25G can be chosen in preference to 22G when performing pancreatic EUS-FNA because 25G was significantly superior to 22G in terms of manipulability and complications although both were effective for accurate diagnosis.

Abstract
With the advent of linear echoendoscopes, endoscopic ultrasound (EUS) has become more operative and a new field of oncological application has been opened up. From tumor staging to tissue acquisition under EUS-guided fine-needle aspiration, new operative procedures have been developed on the principle of the EUS-guided puncture. A hybrid probe combining radiofrequency with cryotechnology is now available, to be passed through the operative channel of the echoendoscope into the tumor to create an area of ablation. EUS-guided fine-needle injection is emerging as a method to deliver anti-tumoral agents inside the tumor. Ethanol lavage, with or without paclitaxel, has been proposed for the treatment of cystic tumors in non-resectable cases and complete resolution has been recorded in up to 70%-80%. Many other chemical or biological agents have been investigated for the treatment of pancreatic adenocarcinoma: activated allogenic lymphocyte culture (Cytoimplant), a replication-deficient adenovirus vector carrying the tumor necrosis factor-α gene, or an oncolytic attenuated adenovirus (ONYX-015). The potential advantage of treatment under EUS control is the real-time imaging guidance into a deep target like the pancreas which is extremely difficult to reach by a percutaneous approach. To date there are no randomized controlled trials to confirm the real clinical benefits of these treatments compared to standard therapy so it seems wise to reserve them only for experimental protocols approved by ethics committees.

Abstract
Endoscopic retrograde cholangiopancreatography (ERCP) is a technically-demanding procedure. The ability to selectively cannulate the bile duct and pancreatic duct (PD) quickly and atraumatically is the key to successful therapeutic ERCP, and to minimizing post-ERCP complications, especially pancreatitis (PEP). Prophylactic stenting of the PD has significantly reduced the risk of severe PEP. Difficult ERCP access refers to the length of time and number of attempts it takes to achieve deep cannulation of the desired duct. If biliary access cannot be achieved quickly, PD stenting over a guide wire is recommended, which facilitates further attempts to enter the bile duct. Familiarity with guide wires and needle knife papillotomy technique are necessary to achieve close to 100 % biliary cannulation. Anatomic abnormalities, from gastric outlet strictures, periampullary diverticula, and ampullary masses to surgical rearrangement of the upper GI tract, contribute to the difficulty of performing ERCP. Adjunctive techniques to overcome these problems include percutaneous transhepatic biliary access and endoscopic ultrasound (EUS)-guided puncture of the bile duct through the stomach or duodenal wall. Therapeutic EUS is emerging as a major tool in the management of pancreatic and biliary disease, and will likely replace many therapeutic ERCP techniques in the next decade.

Abstract
BACKGROUND AND OBJECTIVE EUS-FNA of pancreatic lesion has been put into clinical use widely in many centers. The present meta-analysis was conducted to study the diagnostic role of EUS-FNA in pancreatic cancer. METHODS A comprehensive review of study on the precision of EUS-FNA in the diagnosis of pancreatic cancer. A random effects model was used to pool the sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR) and diagnostic odds ratio (DOR). A summary receiver-operating characteristic (SROC) was constructed to summarize the overall test performance. RESULTS Thirty-one articles were eligible for the meta-analysis. The pooled sensitivity, specificity, PLR, NLR and DOR of EUS-FNA in the diagnosis of pancreatic cancer were 0.89 (95% CI: 0.88-0.90), 0.96 (95% CI: 0.95-0.97), 16.88 (95% CI: 10.63-26.79), 0.13 (95%CI: 0.10-0.16) and 150.80 (95%CI: 95.94-237.03) respectively. In subgroup meta-analysis of the prospective studies, the pooled sensitivity, specificity, PLR, NLR and DOR were 0.91 (95% CI: 0.90-0.93), 0.94 (95% CI: 0.91-0.96), 11.19 (95% CI: 6.36-19.69), 0.10 (95% CI: 0.07-0.15) and 125.22 (62.37-251.41). The area under the curve (AUC) was 0.97, indicating a good performance of overall accuracy. CONCLUSION EUS-FNA has the high sensitivity and specificity in differentiating pancreatic cancer. Moreover, it is also a safe diagnostic modality with little complications.

Feasibility and safety of EUS-guided cryothermal ablation in patients with locally advanced pancreatic cancer. Gastrointest Endosc 2012; 76:1142-51. [PMID: 23021160 DOI: 10.1016/j.gie.2012.08.006] [Citation(s) in RCA: 102] [Impact Index Per Article: 8.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/28/2011] [Accepted: 08/05/2012] [Indexed: 02/05/2023]
Abstract
BACKGROUND New therapies are needed for pancreatic cancer. OBJECTIVE To determine the feasibility and safety of a new endoscopic treatment. Secondary endpoints were to determine effects on tumor growth measured with CT scan and to find the overall survival. DESIGN A cohort study of patients with local progression of advanced pancreatic adenocarcinoma after neoadjuvant therapy. The cryotherm probe (CTP), a flexible bipolar device that combines radiofrequency with cryogenic cooling, was used under EUS guidance. SETTING San Raffaele Hospital, Milan, Italy; University Medical Center, Hamburg-Eppendorf, Germany. PATIENTS A total of 22 patients (male/female 11/11; mean age 61.9 years) were enrolled from September 2009 to May 2011. INTERVENTION Radiofrequency heating: 18 W; pressure for cooling: 650 psi (Pounds per Square Inch); application time: depending on tumor size. MAIN OUTCOME MEASUREMENTS Feasibility was evaluated during the procedure. A clinical and radiologic follow-up was planned. RESULTS The CTP was successfully applied in 16 patients (72.8%); in 6 it was not possible because of stiffness of the GI wall and of the tumor. Amylase arose in 3 of 16 patients; none had clinical signs of pancreatitis. Late complications arose in 4 cases: 3 were mostly related to tumor progression. Median postablation survival time was 6 months. A CT scan was performed in all patients, but only in 6 of 16 was it possible to clearly define the tumor margins after ablation. In these patients, the tumor appeared smaller compared with the initial mass (P = .07). LIMITATIONS Small sample of patients, difficulty of objectifying the size of the ablated zone by CT scan. CONCLUSION EUS-guided CTP ablation is feasible and safe. Further investigations are needed to demonstrate progression-free survival and local control.

[PMID: 23251895 PMCID: PMC3521949 DOI: 10.5946/ce.2012.45.4.431] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/06/2012] [Revised: 05/04/2012] [Accepted: 07/04/2012] [Indexed: 12/16/2022] Open
Abstract
Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is well known as a safe diagnostic procedure. We report the first case of pancreatic pseudocyst after EUS-FNA of the pancreatic body mass. A 60-year-old male underwent EUS-FNA for incidentally detected pancreatic solid mass which was suspected as neuroendocrine tumor. Two weeks later, the patient visited emergency room with acute abdominal pain and right upper quadrant tenderness; leukocytosis and elevated C-reactive protein, amylase, and lipase levels were noted. Computed tomography discovered newly developed 11.5×9.5 cm sized cystic mass communicating with the main pancreatic duct. Cyst fluid analysis revealed amylase level of 3,423 U/L and fluid culture isolated Streptococcus parasanguinis. The cystic mass corresponds with pancreatic pseudocyst. FNA induced main pancreatic duct injury and fluid leakage may cause it. Endoscopists who perform EUS-FNA must remember that pancreatic main duct injury can occur as one of severe complications and that it could be treated successfully with endoscopic internal drainage.

Abstract
Endoscopy has an increasingly important role in the palliation of patients with pancreatic ductal adenocarcinoma. Endoscopic biliary drainage is still requested in the majority of patients who present with obstructive jaundice, and the increased use of self-expandable metallic stents has reduced the incidence of premature stent occlusion. First-line use of metallic stents is expected to be utilized more frequently as neoadjuvant protocols are improved. The efficacy of endoscopy for palliating gastroduodenal obstruction has advanced with the development of through-the-scope, self-expandable gastroduodenal stents. There have been advances in pain management, with endoscopic ultrasound-guided celiac plexus neurolysis reducing opiate requirements and pain for patients with unresectable malignancy. Future applications of endoscopy in pancreatic cancer may include fine-needle injection of chemotherapeutic and other agents into the lesion itself. This review will summarize the evidence of endoscopy in the management of patients with pancreatic cancer.

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
Endoscopic ultrasound (EUS) is a viable and often preferred alternative to interventional and radiologic procedures, and the therapeutic applications of EUS continue to evolve. This evolution was catalyzed by the introduction of linear echoendoscopes that provide continuous imaging and observation of needles and by therapeutic devices that pass through large-caliber working channels. In this paper, we will discuss the spectrum of EUS-guided interventions that are currently available and in development.

Abstract
BACKGROUND Pain management of many pancreatic diseases remains a major clinical concern. This problem reflects our poor understanding of pain signaling from the pancreas. OBJECTIVES This review provides an overview of our current knowledge, with emphasis on current pain management strategies and recent experimental findings. METHODS A systematic search of the scientific literature was carried out using EMBASE, PubMed/MEDLINE, and the Cochrane Central Register of Controlled Trials for the years 1965-2011 to obtain access to all publications, especially randomized controlled trials, systematic reviews, and meta-analyses exploring pain and its management in disease states such as acute pancreatitis (AP), chronic pancreatitis (CP) and pancreatic cancer (PC). RESULTS Over the last decade, numerous molecular mediators such as nerve growth factor and the transient receptor potential (TRP) cation channel family have been implicated in afferent nerve signaling. More recent animal studies have indicated the location of the receptive fields for the afferent nerves in the pancreas and shown that these are activated by agents including cholecystokinin octapeptide, 5-hydroxytryptamine and bradykinin. Studies with PC specimens have shown that neuro-immune interactions occur and numerous agents including TRP cation channel V1, artemin and fractalkine have been implicated. Experimental studies in the clinical setting have demonstrated impairment of inhibitory pain modulation from supraspinal structures and implicated neuropathic pain mechanisms. CONCLUSIONS Our knowledge in this area remains incomplete. Characterization of the mediators and receptors/ion channels on the sensory nerve terminals are required in order to facilitate the development of new pharmaceutical treatments for AP and CP.

Abstract
BACKGROUND Endoscopic ultrasound staging and guided fine needle aspiration biopsy (EUS-FNA) is a highly accurate diagnostic method, useful in characterizing pancreatic lesions, obtaining definitive tissue diagnosis in patients with suspected pancreatic lesions, and providing accurate locoregional staging that enhances diagnostic certainty and evaluation of appropriateness of surgical intervention. The aims of this study were to evaluate the preoperative contribution of EUS staging and EUS-FNA in patients with suspected resectable pancreatic malignancies. PATIENTS AND METHODS A prospective study was conducted in a tertiary referral center. During a 54-month period, a total of 103 consecutive patients were prospectively evaluated with EUS and EUS-FNA. Enrolled in the study were patients with resectable pancreatic lesions, who underwent surgery. RESULTS The overall operating characteristics of EUSFNA were sensitivity 96.7%, specificity 90.0%, positive predictive value 98.9%, negative predictive value 75.0%, and diagnostic accuracy 96.1%. CONCLUSION EUS and EUS-FNA have a high accuracy and positive predictive value in the preoperative determination of resectability in pancreatic cancer.

Abstract
BACKGROUND Cystic lesions of the pancreas are being identified more frequently, and a selective approach to resection is now recommended. The aim of this study was to assess the change in presentation and management of pancreatic cystic lesions evaluated at a single institution over 15 years. STUDY DESIGN A prospectively maintained registry of patients evaluated between 1995 and 2010 for the ICD-9 diagnosis of pancreatic cyst was reviewed. The 539 patients managed from 1995 to 2005 were compared with the 885 patients managed from 2005 to 2010. RESULTS A total of 1,424 patients were evaluated, including 1,141 with follow-up >6 months. Initial management (within 6 months of first assessment) was operative in 422 patients (37%) and nonoperative in 719 patients (63%). Operative mortality in patients initially submitted to resection was 0.7% (n = 3). Median radiographic follow-up in patients initially managed nonoperatively was 28 months (range 6 to 175 months). Patients followed radiographically were more likely to have cysts that were asymptomatic (72% versus 49%, p < 0.001), smaller (1.5 versus 3 cm, p < 0.001), without solid component (94% versus 68%, p < 0.001), and without main pancreatic duct dilation (88% versus 61%, p < 0.001). Changes prompting subsequent operative treatment occurred in 47 patients (6.5%), with adenocarcinoma identified in 8 (17%) and pancreatic endocrine neoplasm in 4 (8.5%). Thus, of the 719 patients initially managed nonoperatively, invasive malignancy was identified in 12 (1.7%), with adenocarcinoma seen in 1.1%. CONCLUSION Cystic lesions of the pancreas are being identified more frequently, yet are less likely to present with concerning features of malignancy. Carefully selected patients managed nonoperatively had a risk of malignancy that was equivalent to the risk of operative mortality in those patients who initially underwent resection.

Abstract
Pancreatic cytopathology plays a critical role in the management of patients with cystic and solid pancreatic masses. The frequency of pancreatic fine-needle aspiration continues to increase and general surgical pathologists and cytopathologists need to be aware of the most commonly encountered entities as well as the pitfalls associated with gastrointestinal tract contaminants in endoscopic ultrasound-guided fine-needle aspiration. This article focuses on the most commonly encountered pancreatic lesions and the importance of correlation of cytologic features with clinical, radiologic, and ancillary studies for accurate diagnosis.

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
UNLABELLED The aim was to evaluate the diagnostic value of (18)F-fluorodeoxyglucose-positron emission tomography ((18)F-FDG PET), combined (18)F-fluorodeoxyglucose-positron emission tomography/computed tomography ((18)F-FDG PET/CT) and endoscopic ultrasonography (EUS) in diagnosing patients with pancreatic carcinoma. MEDLINE, EMBASE, Cochrane library and some other databases, from January 1966 to April 2009, were searched for initial studies. All the studies published in English or Chinese relating to the diagnostic value of (18)F-FDG PET, PET/CT and EUS for patients with pancreatic cancer were collected. Methodological quality was assessed. The statistic software called "Meta-Disc 1.4" was used for data analysis. RESULTS 51 studies were included in this meta-analysis. The pooled sensitivity estimate for combined PET/CT (90.1%) was significantly higher than PET (88.4%) and EUS (81.2%). The pooled specificity estimate for EUS (93.2%) was significantly higher than PET (83.1%) and PET/CT (80.1%). The pooled DOR estimate for EUS (49.774) was significantly higher than PET (32.778) and PET/CT (27.105). SROC curves for PET/CT and EUS showed a little better diagnostic accuracy than PET alone. For PET alone, when interpreted the results with knowledge of other imaging tests, its sensitivity (89.4%) and specificity (80.1%) were closer to PET/CT. For EUS, its diagnostic value decreased in differentiating pancreatic cancer for patients with chronic pancreatitis. In conclusion, PET/CT was a high sensitive and EUS was a high specific modality in diagnosing patients with pancreatic cancer. PET/CT and EUS could play different roles during different conditions in diagnosing pancreatic carcinoma.
