Abstract
Cancer is one of the foremost health problems worldwide and is among the leading causes of death in the United States. Gastrointestinal tract cancers account for almost one third of the cancer-related mortality globally, making it one of the deadliest groups of cancers. Early diagnosis and prompt management are key to preventing cancer-related morbidity and mortality. With advancements in technology and endoscopic techniques, endoscopy has become the core in diagnosis and management of gastrointestinal tract cancers. In this extensive review, the authors discuss the role endoscopy plays in early detection, diagnosis, and management of esophageal, gastric, colorectal, pancreatic, ampullary, biliary tract, and small intestinal cancers.

Abstract
BACKGROUND Accurate preoperative assessment of ampullary tumors (ATs) is critical for determining the appropriate treatment. The reported diagnostic accuracy of endoscopic ultrasound (EUS) and intraductal ultrasonography (IDUS) for detecting tumor depth (T-staging) and regional lymph node status (N-staging) varies across studies. METHOD An electronic search of the MEDLINE and Embase databases was conducted to identify studies that assessed the diagnostic accuracy of EUS and IDUS for ATs. Sensitivities and specificities of eligible studies were summarized using either fixed effects or random-effects model. RESULTS Twenty-one studies were included in the final analysis. The pooled sensitivity and specificity of EUS were 0.89 and 0.87 for T1, 0.76 and 0.91 for T2, 0.81 and 0.94 for T3 and 0.72 and 0.98 for T4, respectively. For IDUS, estimates from five studies were 0.90 and 0.88 for T1, 0.73 and 0.91 for T2 and 0.79 and 0.97 for T3, respectively. For N-staging, 16 studies using EUS were included with sensitivity and specificity of 0.61 and 0.77, respectively. Moreover, estimates of IDUS for N-staging were 0.61 and 0.92, respectively. CONCLUSION Our results imply that EUS and IDUS have good diagnostic accuracy for T-staging of ATs. However, the accuracy of EUS or IDUS is less satisfactory for N-staging. More well-designed prospective studies are warranted to confirm our findings.

Abstract
BACKGROUND Neuroendocrine neoplasms of the ampulla of Vater (ampullary NEN) have features of both gastrointestinal and pancreato-biliary (PB) NEN. However, the limited number of studies examining ampullary NEN makes it difficult to clarify their unique characteristics. This study aimed to elucidate the clinical characteristics of ampullary NEN. METHODS We enrolled 162 patients with PB-NEN diagnosed at Kyushu University Hospital between 2011 and 2020. Clinical features, pathological diagnoses, treatments, and prognoses were retrospectively analyzed. We also compared ampullary NEN with pancreatic NEN (PanNEN). RESULTS We analyzed 10 ampullary NEN cases and 149 PanNEN cases. The ampullary NEN cases consisted of 4 cases of neuroendocrine tumor Grade 1 (NET G1), 1 NET G2 (Grade 2), and 5 neuroendocrine carcinomas (NECs). The incidences of NEC and cholangitis were significantly higher in ampullary NEN than in PanNEN. All ampullary NETs had a submucosal tumor-like appearance, as identified by endoscopic ultrasound-guided fine needle aspiration. We treated small NET G1 (<10 mm) with endoscopic papillectomy and large NET G1 with pancreaticoduodenectomy. There were no cases of recurrence after resection. All ampullary NECs presented with the characteristic endoscopic finding of a "crater sign" similar to deep-mining ulcers seen in gastric malignant lymphoma. Four cases underwent surgical resection, and 1 case was unresectable. Two patients who underwent multidisciplinary treatment were maintained without recurrence for over 2 years. CONCLUSIONS Endoscopic findings showed identifiable distinctions between ampullary NETs and NECs.

Abstract
Ampullary adenomatous lesions of the gastrointestinal tract are rare and can be asymptomatic. Therefore, ampullary adenomas with malignant potential require prompt removal, regardless of whether they are adenomatous or carcinomatous lesions. Endoscopic papillectomy is a safe and effective alternative therapy to surgery to treat duodenal papillary lesions in selected patients. Accurate preoperative diagnosis and staging of ampullary adenomatous lesions are critical for predicting prognosis and determining the most appropriate therapeutic approach. Furthermore, the management and prevention of adverse events and endoscopic treatment for remnant or recurrent lesions and surveillance are essential for successful endoscopic management of ampullary adenomatous lesions. This literature review was based on PubMed and MEDLINE and focused on recent advancements in the endoscopic papillectomy technique to provide a comprehensive view of endoscopic papillectomy to treat ampullary adenomatous lesions.

Abstract
OBJECTIVE To develop the indications and assess an effectiveness of treatment of patients with ampullary tumors followed by mechanical jaundice. MATERIAL AND METHODS There were 26 patients with major duodenal papilla neoplasms for the period 2015-2020 at the Sklifosovsky Research Institute for Emergency Care. RESULTS Twenty patients underwent transpapillary interventions: papillosphincterotomy followed by lithoextraction and bilio-duodenal stenting in 4 (15.3%) patients, bilio-duodenal stenting in 12 (46.1%) patients, nasobiliary drainage in 2 (7.6%) patients, pancreaticoduodenal stenting in 2 (7.6%) patients. Percutaneous transhepatic microcholecystostomy was performed in 6 (23.4%) patients. In all cases, laboratory values decreased in 5-7 days after drainage. Eight (30.7%) patients refused further surgical treatment and were discharged in satisfactory condition. Another 8 (44.5%) patients underwent endoscopic submucosal papillectomy. There were no postoperative complications. Patients were discharged after 5-7 days. Four (22.2%) patients underwent tumor resection via laparotomy. One of these patients required redo laparotomy in postoperative period due to acute perforated duodenal ulcer. Six (33.3%) patients underwent palliative bilio-duodenal stenting. CONCLUSION Invasion of muscle layer or distal parts of the common bile duct, as well as abnormal vascularization are indications for open surgery or palliative endoscopic treatment. Tumor location within mucous and muscle layers without invasion of distal third of the common bile duct and no abnormal vascularization of tumor justify endoscopic papillectomy. Endoscopic approach can be considered as a final minimally invasive method with minimal risk of postoperative complications in case of benign ampullary tumor.

Abstract
1: ESGE recommends against diagnostic/therapeutic papillectomy when adenoma is not proven.Strong recommendation, low quality evidence. 2: ESGE recommends endoscopic ultrasound and abdominal magnetic resonance cholangiopancreatography (MRCP) for staging of ampullary tumors.Strong recommendation, low quality evidence. 3: ESGE recommends endoscopic papillectomy in patients with ampullary adenoma without intraductal extension, because of good results regarding outcome (technical and clinical success, morbidity, and recurrence).Strong recommendation, moderate quality evidence. 4: ESGE recommends en bloc resection of ampullary adenomas up to 20-30 mm in diameter to achieve R0 resection, for optimizing the complete resection rate, providing optimal histopathology, and reduction of the recurrence rate after endoscopic papillectomy.Strong recommendation, low quality evidence. 5: ESGE suggests considering surgical treatment of ampullary adenomas when endoscopic resection is not feasible for technical reasons (e. g. diverticulum, size > 4 cm), and in the case of intraductal involvement (of > 20 mm). Surveillance thereafter is still mandatory.Weak recommendation, low quality evidence. 6: ESGE recommends direct snare resection without submucosal injection for endoscopic papillectomy.Strong recommendation, moderate quality evidence. 7: ESGE recommends prophylactic pancreatic duct stenting to reduce the risk of pancreatitis after endoscopic papillectomy.Strong recommendation, moderate quality evidence. 8: ESGE recommends long-term monitoring of patients after endoscopic papillectomy or surgical ampullectomy, based on duodenoscopy with biopsies of the scar and of any abnormal area, within the first 3 months, at 6 and 12 months, and thereafter yearly for at least 5 years.Strong recommendation, low quality evidence.

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

Abstract
Upper tract urothelial carcinoma (UTUC) initially presents with hematuria and hydronephrosis. We report a case of UTUC presenting with initial findings of duodenal stenosis before the appearance of hydronephrosis. A 59-year-old man presented with upper abdominal symptoms on his initial visit. Esophagogastroduodenoscopy (EGD) revealed circumferential stenosis at the descending part of the duodenum. However, the underlying cause of duodenal stenosis was unknown as repeated histopathological examinations of endoscopic biopsy specimens showed no specific findings. We then performed endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) of the thickened duodenal wall, and successfully diagnosed duodenal metastasis of UTUC. EUS-FNA is an effective diagnostic method in cases in which the cause of duodenal stenosis is unknown.

Abstract
Malignant biliary obstruction is a challenging condition, requiring a multimodal approach for both diagnosis and treatment. Pancreatic adenocarcinoma and cholangiocarcinoma are the leading causes of malignant distal biliary obstruction. Early diagnosis is difficult to establish as biliary obstruction can be the first presentation of the underlying disease, which can already be at an advanced stage. Consequently, the majority of patients (70%) with malignant distal biliary obstruction are unresectable at the time of diagnosis. The association of clinical findings, laboratory tests, imaging, and endoscopic modalities may help in identifying the underlying cause. Novel endoscopic techniques such as cholangioscopy, intraductal ultrasonography, or confocal laser endomicroscopy have been developed with promising results, but are not used in routine clinical practice. As the number of patients with malignant distal biliary obstruction who will undergo curative surgery is limited, endoscopy has a crucial role in palliation, to relieve biliary obstruction. According to the last European guidelines published in the management of biliary obstruction, self-expandable metal stents have a central place in biliary drainage compared to plastic stents. Endoscopic ultrasound has evolved impressively in the last decades. When standard techniques of biliary cannulation by endoscopic retrograde cholangiopancreatography fail, endoscopic ultrasound-guided biliary drainage is a good option compared to percutaneous drainage.

Abstract
Small intestinal adenomas are uncommon. Majority of these occur in the region of the ampulla of Vater. Adenomas of the ampulla can be further subdivided into two types-intestinal and pancreatobiliary. While intestinal adenomas are more frequent, pancreatobiliary adenomas are rare. There is limited literature regarding the role of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) in the diagnosis of ampullary/peri-ampullary neoplasms. Here, we describe the cytologic features of a pancreatobiliary neoplasm of the duodenum that was sampled by EUS-FNA. The aspirate was cellular and revealed cells with moderately abundant oncocytic cytoplasm. The nuclei were round with fine chromatin and focally prominent nucleoli. Although the concurrent biopsy showed no high-grade dysplasia or invasive carcinoma, the EUS and imaging findings were highly suspicious for invasion. A broad differential diagnosis is under consideration for a duodenal mass that encompasses neoplasms of the biliary tract, pancreas, duodenum, and ampulla of Vater. To our knowledge, cytologic features of a pancreatobiliary neoplasm of the duodenum have not been previously reported. Our case highlights the features seen on cytology with histologic correlation in the hopes of elucidating features to better characterize these lesions.

Abstract
Ampulla of Vater is a peculiar anatomical structure, characterized by the crossroad of three distinct epithelia: Intestinal, ductal pancreatic and biliary. Adenocarcinomas arising in this area represent an opportunity to understand the comparative biology of all periampullary malignancies. These neoplasms can exhibit intestinal, pancreaticobiliary or mixed features, whereas the subclassification based on morphology and immunohistochemical features failed in demonstrating a robust prognostic reliability. In the last few years, the molecular landscape of this tumor entity has been uncovered, identifying alterations that may serve as prognostic and predictive biomarkers. In this review, the histological and genetic characteristics of ampullary carcinomas are discussed, taking into account the main clinical and therapeutic implications related to this tumor type as well.

Abstract
Adenomas of the ampulla of Vater are distinctly rare, representing <10% of periampullary neoplasms. Very few reports of the cytologic features of ampullary adenomas are present in literature, particularly in bile duct brushing samples. A case report and review of the literature is presented. The typical cytologic features of ampullary adenomas on cytologic preparations include tall, thin columnar cells with mildly hyperchromatic elongated nuclei and nuclear pseudostratification, in a relatively clean background. The key differential diagnostic entities include invasive adenocarcinoma, thermal artifact, and reactive atypia.

Abstract
BACKGROUND The accuracy of EUS in the locoregional assessment of ampullary lesions is unclear. OBJECTIVES To compare EUS with ERCP and surgical pathology for the evaluation of intraductal extension and local staging of ampullary lesions. DESIGN Retrospective cohort study. SETTING Tertiary-care referral center. PATIENTS All patients who underwent EUS primarily for the evaluation of an ampullary lesion between 1998 and 2012. INTERVENTION EUS. MAIN OUTCOME MEASUREMENTS Comparison of EUS sensitivity/specificity for intraductal and local extension with ERCP and surgical pathology by using the area under the receiver-operating characteristic (AUROC) curves and outcomes of the subgroup referred for endoscopic papillectomy. RESULTS We identified 119 patients who underwent EUS for an ampullary lesion, of whom 99 (83%) had an adenoma or adenocarcinoma. Compared with ERCP (n = 90), the sensitivity/specificity of EUS for any intraductal extension was 56%/97% (AUROC = 0.77; 95% confidence interval [CI], 0.64-0.89). However, when using surgical pathology as the reference (n = 102), the sensitivity/specificity of EUS (80%/93%; AUROC = 0.87; 95% CI, 0.76-0.97) and ERCP (83%/93%; AUROC = 0.88; 95% CI, 0.77-0.99) were comparable. The overall accuracy of EUS for local staging was 90%. Of 58 patients referred for endoscopic papillectomy, complete resection was achieved in 53 (91%); in those having intraductal extension by EUS or ERCP, complete resection was achieved in 4 of 5 (80%) and 4 of 7 (57%), respectively. LIMITATION Retrospective design. CONCLUSIONS EUS and ERCP perform similarly in evaluating intraductal extension of ampullary adenomas. Additionally, EUS is accurate in T-staging ampullary adenocarcinomas. Future prospective studies should evaluate whether EUS can identify characteristics of ampullary lesions that appropriately direct patients to endoscopic or surgical resection.

Abstract
BACKGROUND AND AIM Accurate preoperative staging of ampullary neoplasms is of paramount importance in predicting prognosis and determining the most appropriate therapeutic approach. The aim of the present review was to evaluate the accuracy of endoscopic ultrasound (EUS) in predicting depth of ampullary tumor invasion (T-stage) and regional lymph node status (N-stage) by carrying out a meta-analysis of all relevant studies. METHODS We systematically searched PubMed, Medline and Scopus databases for all studies published between January 1980 and December 2012. Only EUS studies involving ≥ 10 patients with ampullary neoplasms, confirmed by surgical histopathology, with data available for construction of a 2 × 2 table were included. RESULTS Meta-analysis of 14 studies involving 422 patients using the Mantel-Haenszel method was performed. Pooled sensitivity and specificity of EUS to diagnose T1-stage tumor were 77% (95% CI: 69-83) and 78% (95% CI: 72-84), respectively. Pooled sensitivity for T4 tumors was 84% (95% CI: 73-92) and specificity was 74% (95% CI: 63-83). Combined sensitivity, specificity, positive likelihood ratio, negative likelihood ratio and diagnostic odds ratio for diagnosing nodal status were 0.70 (95% CI: 0.62-0.77), 0.74 (95% CI: 0.67-0.0.80), 2.49 (95% CI: 1.91-3.24), 0.46 (95% CI: 0.36-0.59) and 6.53 (95% CI: 3.81-11.19), respectively. CONCLUSION Based on our pooled estimates, EUS had a moderate strength of agreement with histopathology in preoperative staging of ampullary neoplasms in predicting tumor invasion and lymph node involvement. Additional refinement in EUS technologies and diagnostic criteria may be required to enhance staging accuracy.

Abstract
Objective: No previous studies have described endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) only for intra-ampullary lesions of the papilla of Vater. We aimed to examine whether EUS-FNA can be used to diagnose such lesions. Methods: This study included a subset of 10 consecutive patients in whom EUS-FNA targeted the ampulla of Vater. All the patients underwent biopsy and/or brushing cytology under endoscopic retrograde cholangiopancreatography (ERCP) prior to EUS-FNA. The final diagnosis was based on pathological examinations of specimens obtained by surgical resection or clinical follow-up more than 1 year in case of evidence of benign lesions. Results: Tissues from the ampulla of Vater could be obtained by EUS-FNA for all 10 patients. The final diagnosis was papillitis (n = 7) and intra-ampullary carcinoma (n = 3). Carcinoma of the ampulla of Vater showed neither exposure on the duodenal mucosal surface nor invasion to the pancreas. The diagnostic accuracy of surface biopsy with duodenoscopy, and intra-ampullary biopsy and/or brush cytology with ERCP and/or intra-ampullary biopsy after endoscopic sphincterotomy (EST) in distinguishing between benign and malignancy was 70%. The diagnostic accuracy of EUS-FNA was 100%. No complications associated with EUS-FNA were encountered in this study. Conclusion: EUS-FNA for ampulla of Vater may be safely and accurately performed, and should be considered as a diagnostic modality before EST.

Abstract
BACKGROUND Ampullary adenocarcinoma is considered to have a better prognosis than either pancreatic or bile duct adenocarcinoma. Pancreaticoduodenectomy is associated with significant mortality and morbidity. Some recent publications have advocated the use of endoscopic papillectomy for the treatment of early ampullary adenocarcinoma. This article reviews investigations and surgical treatment options of ampullary tumours. METHODS A systematic review of English-language articles was carried out using an electronic search of the Ovid MEDLINE (from 1996 onwards), PubMed and Cochrane Database of Systematic Reviews databases to identify studies related to the investigation and management of ampullary tumours. RESULTS Distinguishing between ampullary adenoma and adenocarcinoma is challenging given the inaccuracy of endoscopic biopsy, for which high false negative rates of 25-50% have been reported. Endoscopic ultrasound is the most accurate method for local staging of ampullary lesions, but distinguishing between T1 and T2 adenocarcinomas is difficult. Lymph node metastasis occurs early in the disease process; it is lowest for T1 tumours, but the risk is still high at 8-45%. Case reports of successful endoscopic resection and transduodenal ampullectomy of T1 adenocarcinomas have been published, but their duration of follow-up is limited. CONCLUSIONS Optimal staging should be used to distinguish between ampullary adenoma and adenocarcinoma. Pancreaticoduodenectomy remains the treatment of choice for all ampullary adenocarcinomas.

Abstract
BACKGROUND Malignant ampullary lesions can be difficult to classify by endoscopy alone. Probe-based confocal laser endomicroscopy (pCLE) permits in vivo assessment of mucosal structures in the gastrointestinal tracts in the real time. AIM The objective of this pilot multicenter study was to assess the interobserver agreement and variance in interpretation of pCLE of ampullary lesions. METHODS Twelve pCLE video clips of ampullary lesions were distributed to 6 gastrointestinal specialists at 5 medical centers, blinded to final pathologic results. Six variables were assessed for interobserver agreement using κ statistics. Variables included an epithelial outer border with irregular thickness, dark epithelium without discernable individual cells, heterogenously distributed elongated crypts, reduced number of goblet cells, neovascularization, and final diagnosis. RESULTS The overall interobserver agreement for all observers was poor to slight for all variables (κ=0.02, 0.05, -0.01, 0.04, 0.018) except for the first variable with fair degree of agreement (κ=0.27). On the basis of experience, 3 observers were classified as less experienced, whereas 3 were classified as most experienced. Upon stratification, the less experienced observers had poor interobserver agreement for all variables, except 1. The most experienced observers had poor agreement for 2 variables, slight agreement for 3 variables, and fair agreement for the final diagnosis variable. CONCLUSIONS The overall interpersonal agreement on pCLE for ampullary lesions was poor. The interobserver agreement was not substantially improved for experienced raters. Further standardization of pCLE image criteria is needed for ampullary lesions. Standardized training may improve interrater reliability to an acceptable level.

Abstract
Endoscopic ultrasound guided fine-needle aspiration biopsy is a reliable and accurate method for the diagnosis of submucosal lesions of the gastrointestinal tract. We report the cytopathologic findings of a case of duodenal high-grade neuroendocrine carcinoma in a 68-year-old woman who presented with melena and marked anemia, 45 years after kidney transplantation. Imaging studies performed in the work-up of melena showed a duodenal mass, which on endoscopy proved to be an exophytic, villous duodenal lesion, 3 cm from the ampulla. Forceps biopsy of the exophytic lesion showed a villous adenoma. Endoscopic ultrasound additionally revealed an underlying submucosal lesion and EUS-guided fine needle aspiration of this submucosal mass and of the enlarged mesenteric lymph nodes was diagnostic of a high-grade neuroendocrine carcinoma. The aspirates showed abundant cellularity with tumor cells arranged in sheets and occasional loose clusters. The neoplastic cells had a moderate amount of pale cytoplasm and large round to oval hyperchromatic nuclei with focally prominent nucleoli. Mitoses, apoptotic bodies and necrotic debris were also present. The tumor cells were strongly and diffusely positive for cytokeratin AE1/AE3, synaptophysin and chromogranin and showed a very high proliferative fraction on Ki67 staining, supporting the diagnosis of a high-grade neuroendocrine carcinoma. This is to our knowledge the first case of high-grade neuroendocrine carcinoma of the duodenum diagnosed by EUS-FNA. This case also emphasizes the diagnostic value of EUS-FNA sampling of the submucosal and intramural component of villous tumors of the gastrointestinal tract when mucosal forceps biopsies show only benign findings.

Abstract
OBJECTIVES The reported median diagnostic yield from endoscopic ultrasound (EUS) fine-needle aspiration (FNA) cytology is 78% (range 39-93%). The aim of this study is to describe a single-centre experience in the diagnostic work-up of solid pancreatic and peripancreatic masses without the benefit of an onsite cytopathologist. METHODS In a consecutive series of 429 EUS examinations performed over a 12-month period by a single operator, 108 were on non-cystic pancreatic or biliary lesions. Data were collected prospectively and the accuracy of FNA was assessed retrospectively using either surgery or repeat imaging as the benchmark in the presence or absence of malignancy. RESULTS Of the 108 FNAs, 102 (94%) were diagnostic, four were falsely negative (FN) and two were atypical and considered equivocal. There were 78 pancreatic lesions, of which 65 were true positives (TP), 11 true negatives (TN) and two FN, giving an overall accuracy of 97% (76/78). Of nine periampullary lesions, two were TP, six were TN and one was FN, giving an overall accuracy of 89% (8/9). The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy of EUS-FNA for pancreatic and periampullary lesions combined were 96%, 100%, 100% [95% confidence interval (CI) 95-100%], 85% (95% CI 62-97%) and 97%, respectively. There were 21 bile duct lesions, of which 10 were TP, eight TN, two atypical and one FN, giving an overall accuracy of 86% (18/21). The sensitivity, specificity, PPV, NPV and accuracy of EUS-FNA for biliary lesions were 91%, 100%, 100% (95% CI 69-100%), 91% (95% CI 59-100%) and 95%, respectively. CONCLUSIONS The diagnostic accuracy of EUS-FNA for pancreatic lesions in our series was 97% and the PPV for the three subgroups of lesion type was 100%; these figures are comparable with the best rates reported in the literature, despite the absence of onsite cytopathology. These rates are potentially a direct result of high-volume practice, dedicated endosonography and cytopathology. These results show that it is possible to achieve high rates of accuracy in places where logistical issues make it impossible to maintain a cytopathologist in the endoscopy suite. In addition, our results contribute to the limited, collective global experience on the effectiveness of EUS-FNA in periampullary and biliary lesions.

Abstract
INTRODUCTION We assessed the incidence and outcome of pancreaticoduodenectomy for patients with a pre-operative benign diagnosis and in patients who had an unexpected diagnosis of benign disease following resection. We have also compared how the introduction of endoscopic ultrasound fine needle aspiration (EUS-FNA) has altered our pre-operative assessment. PATIENTS AND METHODS Between January 1997 and April 2006, 499 patients underwent pancreaticoduodenectomy at the Queen Elizabeth Hospital. Data were collected prospectively. A further 85 patients between 2006 and 2008 had a different diagnostic approach (after imaging these patients have been also studied by EUS-FNA). RESULTS Overall, 78 (15.6%) patients had no malignant disease on final histology. Out of 459 patients who underwent pancreaticoduodenectomy for presumed malignancy, 49 (10.6%) had benign disease (sensitivity, 97%; positive predictive value, 89%). In a further 40 patients with a pre-operative benign diagnosis, we found 11 cases (27%) of malignancy (sensitivity, 37%; negative predictive value, 72%). Following the introduction of EUS-FNA, the sensitivity and specificity of the diagnostic work were 92% and 75%, respectively (positive predictive value, 93%; negative predictive value, 63%). The median follow-up was 35 months (range, 1-116 months). CONCLUSIONS Prior to the introduction of EUS-FNA, a significant number of patients, in whom pancreaticoduodenectomy is carried out for suspected benign disease, turn out to have an underlying malignancy. The use of EUS-FNA has improved the specificity of diagnostic work-up.

Abstract
BACKGROUND AND AIM Although endoscopic papillectomy has been attempted in early stage ampullary cancer (pTis, T1), its curative role and indications remain uncertain. The present study was designed to assess the factors that predict malignancy and lymph node metastasis and to suggest potential indications for endoscopic papillectomy by analyzing clinicopathological data. METHODS We performed a retrospective analysis of clinical and histopathological data of 216 patients with ampullary cancer between 1991 and 2006. RESULTS No tumor in pTis stage had metastasized to lymph nodes and only 9% of tumors in pT1 had metastasized. Tumor size (P = 0.018), depth of invasion (P = 0.021) and venous invasion (P = 0.014) were found to be significantly related to lymph node metastasis. Cases with early stage ampullary cancer of less than 2 cm with a well-differentiated histology and no angiolymphatic invasion (n = 13) showed no lymph node metastasis and no recurrence during a median follow up of 35.9 months. CONCLUSION Endoscopic papillectomy can be adopted as a viable alternative to surgery in patients with early stage ampullary cancer of less than 2 cm in size and with a well-differentiated histology. When a resected specimen has a well-differentiated histology, and there is no resection margin involvement and no angiolymphatic invasion, our findings indicate that subsequent radical surgery is unnecessary.

Abstract
PURPOSE To reappraise the accuracy of transabdominal sonography (US), CT, MRI, and endosonography (EUS) in the diagnosis and staging of ampullary tumors. METHOD We reviewed the medical records and the images of 41 consecutive patients with ampullary tumors. Tumor detection rate and accuracy of TNM (tumor-node-metastasis) staging of malignant tumors were determined. Imaging findings were correlated with histopathologic findings. RESULTS The detection rates for ampullary tumors were 97.6% for EUS, 81.3% for MRI, 28.6% for CT, and 12.2% for US (p < 0.001 for EUS versus CT; p < 0.001 for EUS versus US; p > 0.05 for EUS versus MRI). The accuracy in T staging for ampullary carcinomas was 72.7% for EUS, 53.8% for MRI, and 26.1% for CT (p < 0.01 for EUS versus CT; p > 0.05 for EUS versus MRI). The accuracy in N staging for ampullary carcinomas was 66.7% for EUS, 76.9% for MRI, and 43.5% for CT with no statistically significant difference between the 3 modalities. The sensitivity in detecting malignant lymph nodes was 46.7% for EUS, 25.0% for MRI, and 0% for CT (p < 0.01 for EUS versus CT; p > 0.05 for EUS versus MRI; p > 0.05 for MRI versus CT). Transpapillary stenting, advanced tumor extension (>T2), large tumor size (>2 cm), tumor differentiation, and endoscopic appearance of tumor growth did not significantly influence EUS accuracy in T or N staging (p > 0.05). CONCLUSION EUS was superior to CT and was equivalent to MRI for tumor detection and T and N staging of ampullary tumors. Neither indwelling stents nor tumor size, differentiation, or endoscopic appearance affected the staging accuracy of EUS.

Abstract
Undifferentiated carcinoma with osteoclast-like giant cells of the pancreas is rare. Histologically it mimics the giant cell tumor of the bone and may be associated with a ductal adenocarcinoma. We recently encountered two such cases, both of which were biopsied by EUS-guided FNA. Abundant multinucleated osteoclast-like giant cells and many uniform mononuclear cells were present in case 1 so that the diagnosis was made. In case 2, many mononuclear tumor cells with vacuolated and basophilic cytoplasm were present, and rare osteoclast-like giant cells were seen. A diagnosis of adenocarcinoma was made. In both cases, no conspicuous nuclear pleomorphism was noted in the mononuclear cells or the multinucleated giant cells. The histology of case 2 revealed a pure undifferentiated carcinoma with osteoclast-like giant cells. In addition, a liver biopsy revealed globular amyloidosis. To our knowledge, this is the first report of pancreatic undifferentiated carcinoma with osteoclast-like giant cells sampled by EUS-guided FNA and the first case of hepatic globular amyloidosis associated with this tumor.

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