    Full Text Available Abstract Background A recently published systematic review indicated superiority of duodenum-preserving techniques when compared with pancreatoduodenectomy, for the treatment of patients with chronic pancreatitis in the head of the gland. A multicentre randomised trial to confirm these results is needed. Methods/Design ChroPac aims to investigate differences in quality of life, mortality and morbidity during 24 months after surgery (duodenum-preserving pancreatic head resection versus pancreatoduodenectomy in patients with chronic pancreatitis of the pancreatic head. ChroPac is a randomised, controlled, observer and patient blinded multicentre surgical trial with two parallel comparison groups. The primary outcome measure will be the average quality of life during 24 months after surgery. Statistical analysis is based on the intention-to-treat population. Analysis of covariance will be applied for the intervention group comparison adjusting for age, centre and quality of life before surgery. Level of significance is set at 5% (two-sided and sample size (n = 100 per group is determined to assure a power of 90%. Discussion The ChroPac trial will explore important outcomes from different perspectives (e.g. surgeon, patient, health care system. Its pragmatic approach promises high external validity allowing a comprehensive evaluation of the surgical strategy for treatment of patients with chronic pancreatitis.

    Full Text Available Abstract Background Chronic pancreatitis is an inflammatory disease which is characterized by an irreversible conversion of pancreatic parenchyma to fibrous tissue. Beside obstructive jaundice and pseudocyst formation, about half of the patients need surgical intervention due to untreatable chronic pain during the course of the disease. In most of the patients with chronic pancreatitis, the head of the pancreas is the trigger of the chronic inflammatory process. Therefore, resection of pancreatic head tissue must be the central part of any surgical intervention. However, it is unclear to which extent the surgical procedure must be radical in order to obtain a favourable outcome for the patients. Design A single centre randomized controlled, superiority trial to compare two techniques of duodenum preserving pancreatic head resection. Sample size: 65 patients will be included and randomized intraoperatively. Eligibility criteria: All patients with chronic pancreatitis and indication for surgical resection and signed informed consent. Cumulative primary endpoint (hierarchical model: duration of surgical procedure, quality of life after one year, duration of intensive care unit stay, duration of hospital stay. Reference treatment: Resection of the pancreatic head with dissection of the pancreas from the portal vein and transsection of the gland (Beger procedure. Intervention: Partial Resection of the pancreatic head without transsection of the organ and visualization of the portal vein (Berne procedure. Duration: September 2003-October 2007. Organisation/responsibility The trial is conducted in compliance with the protocol and in accordance with the moral, ethical, regulatory and scientific principles governing clinical research as set out in the Declaration of Helsinki (1989 and the Good Clinical Practice guideline (GCP.

    BACKGROUND:Treatment of chronic pancreatitis (CP) is a challenging condition for surgeons. During the last decades, increasing knowledge about pathophysiology of CP, improved results of major pancreatic resections, and integration of sophisticated diagnostic methods in clinical practice have resulted in signiifcant changes in surgery for CP. DATA SOURCES:To detail the indications for CP surgery, the surgical procedures, and outcome, a Pubmed database search was performed. The abstracts of searched articles about surgical management of CP were reviewed. The articles could be identiifed and further scrutinized. Further references were extracted by cross-referencing. RESULTS: Main indications of CP for surgery are intractable pain, suspicion of malignancy, and involvement of adjacent organs. The goal of surgical treatment is to improve the quality of life of patients. The surgical approach to CP should be individualized according to pancreatic anatomy, pain characteristics, baseline exocrine and endocrine function, and medical co-morbidity. The approach usually involves pancreatic duct drainage and resection including longitudinal pancreatojejunostomy, pancreatoduodenectomy (Whipple's procedure), pylorus-preserving pancreatoduodenectomy, distal pancreatectomy, total pancreatectomy, duodenum-preserving pancreatic head resection (Beger's procedure), and local resection of the pancreatic head with longitudinal pancreatojejunostomy (Frey's procedure). Non-pancreatic and endoscopic management of pain has also been advocated. CONCLUSIONS:Surgical procedures provide long-term pain relief, a good postoperative quality of life with preservation of endocrine and exocrine pancreatic function, and are associated with low early and late mortality and morbidity. In addition to available results from randomized controlled trials, new studies are needed to determine which procedure is the most effective for the management of patients with CP.

    Full Text Available INTRODUCTION: The principal indication for surgical intervention in chronic pancreatitis is intractable pain. Depending upon the presence of dilated pancreatic ductal system, pancreatic duct drainage procedures and different kinds of pancreatic resections are applied. OBJECTIVE: The objective of the study was to show the most appropriate procedure to gain the most possible benefits in dependence of type of pathohistological process in chronic pancreatitis. METHOD: Our study included 58 patients with intractable pain caused by chronic pancreatitis of alcoholic genesis. The first group consisted of 30 patients with dilated pancreatic ductal system more than 10 mm. The second group involved 28 patients without dilated pancreatic ductal system. Pain relief, weight gain and glucose tolerance were monitored. RESULTS: All patients of Group I (30 underwent latero-lateral pancreaticojejunal - Puestow operation. 80% of patients had no pain after 6 month, 13.6% had rare pain and 2 patients, i.e. 6.4%, who continued to consume alcohol, had strong pain. Group II consisting of 28 patients was without dilated pancreatic ductal system. This group was subjected to various types of pancreatic resections. Whipple procedure (W was done in 6 patients, pylorus preserving Whipple (PPW in 7 cases, and duodenum preserving cephalic pancreatectomy (DPCP was performed in 15 patients. Generally, 89.2% of patients had no pain 6 month after the operation. An average weight gain was 1.9 kg in W group, 2.8 kg in PPW group and 4.1 kg in DPCP group. Insulin-dependent diabetes was recorded in 66.6% in W group, 57.1% in PPW group and 0% in DPCP group. CONCLUSION: According to our opinion, DPCP may be considered the procedure of choice for surgical treatment of pain in chronic pancreatitis in patients without dilatation of pancreas ductal system because of no serious postoperative metabolic consequences.

    Therapy of chronic pancreatitis rests on five arms: Avoidance of alcohol, treatment of pain, replacement therapy for exocrine and endocrine insufficiency and adequate nutrition. Alcohol withdrawal improves pain and the patient's compliance. It also seems to retard the chronic inflammatory process. Therapy of pain depends on the pathomechanism of pain. There is a lack of prospective, controlled studies comparing various treatment regimens. Thus, treatment options are partly dependent on the experience of the physician taking care of the patient and include i.e. for pseudocysts: surgical vs percutaneous or endoscopic drainage; for stenosis of the main pancreatic duct close to the papilla: surgical vs endoscopic drainage (stents); for distal bile duct stenosis: endoscopic stents vs biliodigestive anastomosis vs pancreatic head resection; for pancreatic stones: extracorporal shock wave lithotripsy followed by endoscopic stone extraction vs surgery (pancreaticojejunostomy), finally for inflammatory tumor of the pancreatic head combined with pain with or without compression of the distal bile duct or duodenum: duodenum-preserving pancreatic head resection vs Whipple resection. Patients with pain resistant to medical treatment may be candidates for a transcutaneous blockade of the plexus coeliacus or for epidural nerve blockade before one choses a surgical procedure. Application of pancreatic enzymes does not seem to have a major beneficial effect on pancreatic pain. Modification of nutrition has become less restrictive. Thanks to improved substitution with acid resistant porcine pancreatic extracts with high lipase activity, fat restriction is no longer of paramount importance. However, supply with sufficient calories is still difficult due to pain, inadequate compliance and hypermetabolism. PMID:9857767

  9. Duodenal Acidity May Increase the Risk of Pancreatic Cancer in the Course of Chronic Pancreatitis: An Etiopathogenetic Hypothesis

    Directory of Open Access Journals (Sweden)

    Talamini G

    2005-03-01

    Full Text Available Chronic pancreatitis patients have an increased risk of developing pancreatic cancer. The cause of this increase has yet to be fully explained but smoking and inflammation may play an important role. To these, we must now add a new potential risk factor, namely duodenal acidity. Patients with chronic pancreatitis very often present pancreatic exocrine insufficiency combined with a persistently low duodenal pH in the postprandial period. The duodenal mucosa in chronic pancreas patients with pancreatic insufficiency has a normal concentration of s-cells and, therefore, the production of secretin is preserved. Pancreatic ductal cells are largely responsible for the amount of bicarbonate and water secretion in response to secretin stimulation. When gastric acid in the duodenum is not well-balanced by alkaline pancreatic secretions, it may induce a prolonged secretin stimulus which interacts with the pancreatic ductal cells resulting in an increased rate of ductular cell activity and turnover. N-Nitroso compounds from tobacco, identified in human pancreatic juice and known to be important carcinogens, may then act on these active cells, thereby increasing the risk of cancer. Duodenal acidity is probably of particular concern in patients who have undergone a duodenum-preserving pancreatic head resection, since, in this anatomic situation, pancreatic juice transits directly via the jejunal loop, bypassing the duodenum. Patients undergoing a Whipple procedure or side-to-side pancreaticojejunostomy are probably less critically affected because secretions transit, at least in part, via the papilla. If the duodenal acidity hypothesis proves correct, then, in addition to stopping smoking, reduction of duodenal acid load in patients with pancreatic insufficiency may help decrease the risk of pancreatic cancer.

    Full Text Available Introduction. Isolated pancreatic and peripancreatic tuberculosis is a challenging diagnosis due to its rarity and variable presentation. Pancreatic tuberculosis can mimic pancreatic carcinoma. Similarly, autoimmune pancreatitis can appear as a focal lesion resembling pancreatic malignancy. Endoscopic ultrasound-guided fine needle aspiration provides an effective tool for differentiating between benign and malignant pancreatic lesions. The immune processes involved in immunoglobulin G4 related systemic diseases and tuberculosis appear to have some similarities. Case Report. We report a case of a 59-year-old Southeast Asian male who presented with fever, weight loss, and obstructive jaundice. CT scan revealed pancreatic mass and enlarged peripancreatic lymph nodes. Endoscopic ultrasound-guided fine needle aspiration confirmed the presence of mycobacterium tuberculosis. Patient also had high immunoglobulin G4 levels suggestive of autoimmune pancreatitis. He was started on antituberculosis medications and steroids. Clinically, he responded to treatment. Follow-up imaging showed findings suggestive of chronic pancreatitis. Discussion. Pancreatic tuberculosis and autoimmune pancreatitis can mimic pancreatic malignancy. Accurate diagnosis is imperative as unnecessary surgical intervention can be avoided. Endoscopic ultrasound-guided fine needle aspiration seems to be the diagnostic test of choice for pancreatic masses. Long-term follow-up is warranted in cases of chronic pancreatitis.

    Hereditary pancreatitis is an autosomal dominant condition,which results in recurrent attacks of acute pancreatitis,progressing to chronic pancreatitis often at a young age.The majority of patients with hereditary pancreatitis expressone of two mutations (R122H or N29I) in the cationictrypsinogen gene (PRSS1 gene). It has been hypothesisedthat one of these mutations, the R122H mutation causespancreatitis by altering a trypsin recognition site sopreventing deactivation of trypsin within the pancreas andprolonging its action, resulting in autodigestion. Families withthese two mutations have been identified in many countriesand there are also other rarer mutations, which have alsobeen linked to hereditary pancreatitis.Patients with hereditary pancreatitis present in the sameway as those with sporadic pancreatitis but at an earlierage. It is common for patients to remain undiagnosed formany years, particularly ifthey present with non-specificsymptoms. Hereditary pancreatitis should always beconsidered in patients who present with recurrent pancreatitiswith a family history of pancreatic disease. If patients withthe 2 common mutations are compared, those with theR122H mutation are more likely to present at a younger ageand are more likely to require surgical intervention than thosewith N29I. Hereditary pancreatitis carries a 40 % lifetimerisk of pancreatic cancer with those patients aged between50 to 70 being most at risk in whom screening tests maybecome important.

    Tuberculosis of the pancreas is extremely rare and in most of the cases mimics pancreatic carcinoma. There are a number of case reports on pancreatic tuberculosis with various different presentations, but only a few case series have been published, and most of our knowledge about this disease comes from individual case reports. Patients of pancreatic tuberculosis may remain asymptomatic initially and manifest as an abscess or a mass involving local lymph nodes and usually present with non-specific features. Pancreatic tuberculosis may present with a wide range of imaging findings. It is difficult to diagnose tuberculosis of pancreas on imaging studies as they may present with masses, cystic lesions or abscesses and mass lesions in most of the cases mimic pancreatic carcinoma. As it is a rare entity, it cannot be recommended but suggested that pancreatic tuberculosis should be considered in cases with a large space occupying lesions associated with necrotic peripancreatic lymph nodes and constitutional symptoms. Ultrasonography/computed tomography/endosonography-guided biopsy is the recommended diagnostic technique. Most patients achieve complete cure with standard antituberculous therapy. The aims of this study are to review clinical presentation, diagnostic studies, and management of pancreatic tuberculosis and to present our experience of 5 cases of pancreatic tuberculosis.

  13. Pancreatic necrosis

    International Nuclear Information System (INIS)

    Pancreatic necrosis is a possible complication of acute pancreatitis. It is characterized by diffuse inflammation associated with exudation or leakage of pancreatic juice with its proteolytic enzymes into the peripancreatic tissues. Colonic complications of acute pancreatitis are uncommon events. Tha main purpose of our study was to correlate radiological findings of pancreatic necrosis as observed during barium enema to CT patterns. A retrospective study was therefore carried out on 40 patients affected with acute pancreatitis with local and systemic complication. The analysis of the results allowed different patterns to be observed, with the two techniques, in the acute and in the chronich phases. In the acute phase, barium enema of the colon showed inflammatory extrinsic processes involving the wall, with a typical localization related to the spread of pancreatic enzymes along mesenteric pathways, as described by Meyers. CT allowed a thorough evaluation of both the pathologic process and its spatial balance. In the chronic phase, barium enema showed fibrotic trictures and fistulas. CT demonstrated pseudoeystic masses and irregular focal areas of decreased attenuation or irregular pancreatic margins. This correlation shows how an extrinsic inflammatory involvement of the colon with a characteristic tomography may help make a diagnosis and plan therapy

The role of ischemia, lysosomal enzymes, oxygen free radicals, polymorphnuclear cells-byproducts and inflammatory mediators in the pathogenesis of pancreatic necrosis and multiple organ failure has been emphasized. Furthermore, the recent knowledge about agents infecting pancreatic necrosis, routes of infection, bacteriological examination of fine needle aspirate and appropriate antibiotics have changed the concept of acute pancreatitis. New diagnostic tests such as rapid urinary trypsinogen-2 test and inflammatory mediators including polymorphnuclear elastase, C-reactive protein and interleukin-6 contribute to early diagnosis, prognostic evaluation and initiation of an appropriate therapy.

    Autoimmune pancreatitis (AIP), in contrast to other benign chronic pancreatic diseases, can be cured with immunosuppressant drugs, thus the differentiation of AIP from pancreatic cancer is of particular interest in clinical practice. There is the possibility that some patients with AIP may develop pancreatic cancer, and this possibility contributes to increasing our difficulties in differentiating AIP from pancreatic cancer.

    A prospective study was performed on the relationship of CT findings to the clinical course of 148 patients with acute pancreatitis. The type of pancreatic inflammation seen on CT was classified into six categories based on an overall assessment of size, contour and density of the gland, and peripancreatic abnormalities. The majority (94%) of patients in whom CT showed mild pancreatic changes (grades A, B and C) had two or less positive clinical indicaters of severe pancreatitis (Ranson's signs). In contrast, 92% of patients in whom CT showed more severe changes of pancreatitis (grades D, E or F) had three or more positive signs. The nine patients who died with pancreatitis-related complications were in grades D, E or F. We wish to draw attention to a CT appearance which we have called 'fat islets' (low density intrapancreatic or peripancreatic areas, the contents of which approach fat in attenuation values); there was a strong correlation between this appearance and subsequent infection.

    Pancreatic cancer is a major cause of cancer-associated mortality, with a dismal overall prognosis that has remained virtually unchanged for many decades. Currently, prevention or early diagnosis at a curable stage is exceedingly difficult; patients rarely exhibit symptoms and tumours do not display sensitive and specific markers to aid detection. Pancreatic cancers also have few prevalent genetic mutations; the most commonly mutated genes are KRAS, CDKN2A (encoding p16), TP53 and SMAD4 - none of which are currently druggable. Indeed, therapeutic options are limited and progress in drug development is impeded because most pancreatic cancers are complex at the genomic, epigenetic and metabolic levels, with multiple activated pathways and crosstalk evident. Furthermore, the multilayered interplay between neoplastic and stromal cells in the tumour microenvironment challenges medical treatment. Fewer than 20% of patients have surgically resectable disease; however, neoadjuvant therapies might shift tumours towards resectability. Although newer drug combinations and multimodal regimens in this setting, as well as the adjuvant setting, appreciably extend survival, ∼80% of patients will relapse after surgery and ultimately die of their disease. Thus, consideration of quality of life and overall survival is important. In this Primer, we summarize the current understanding of the salient pathophysiological, molecular, translational and clinical aspects of this disease. In addition, we present an outline of potential future directions for pancreatic cancer research and patient management. PMID:27158978

  3. Pancreatic pseudocyst

    Institute of Scientific and Technical Information of China (English)

    Samir Habashi; Peter V Draganov

    2009-01-01

    Pancreatic pseudocysts are complications of acute or chronic pancreatitis. Initial diagnosis is accomplished most often by cross-sectional imaging. Endoscopic ultrasound with fine needle aspiration has become the preferred test to help distinguish pseudocyst from other cystic lesions of the pancreas. Most pseudocysts resolve spontaneously with supportive care. The size of the pseudocyst and the length of time the cyst has been present are poor predictors for the potential of pseudocyst resolution or complications, but in general, larger cysts are more likely to be symptomatic or cause complications. The main two indications for some type of invasive drainage procedure are persistent patient symptoms or the presence of complications (infection, gastric outlet or biliary obstruction, bleeding). Three different strategies for pancreatic pseudocysts drainage are available: endoscopic (transpapillary or transmural) drainage, percutaneous catheter drainage, or open surgery. To date, no prospective controlled studies have compared directly these approaches. As a result, the management varies based on local expertise, but in general, endoscopic drainage is becoming the preferred approach because it is less invasive than surgery, avoids the need for external drain, and has a high long-term success rate. A tailored therapeutic approach taking into consideration patient preferences and involving multidisciplinary team of therapeutic endoscopist, interventional radiologist and pancreatic surgeon should be considered in all cases.

    2009-05-01

    Full Text Available The present review is focused on the clinical significance of lactoferrin in pancreatic secretions and stone formation in chronic pancreatitis, and of serum anti-lactoferrin antibody in autoimmune pancreatitis. Lactoferrin secretion is increased in pancreatic secretions in calcified and non-calcified chronic pancreatitis. Lactoferrin, pancreatic stone protein and trypsin are present in pancreatic stones. We cannot conclude which protein is more important for the precipitate and stone formation. The presence of antilactoferrin antibody has been reported in serum in autoimmune diseases, such as autoimmune pancreatitis. The coincidental appearance of autoimmune pancreatitis with extrapancreatic autoimmune diseases strongly suggests a common autoimmune mechanism and lactoferrin is a candidate antigen. Lactoferrin may play an important role as a precipitate protein in pancreatic stone formation in chronic pancreatitis and as an autoantigen in autoimmune pancreatitis. Further studies are required to better understand the role of lactoferin.

    Solitary pancreatic involvement of tuberculosis is rare,especially in an immunocompetent individual, and it may be misdiagnosed as pancreatic cystic neoplasms.Pancreatic cystic neoplasms are being identified in increasing numbers, probably because of the frequent use of radiology and advances in endoscopic techniques.However, they are composed of a variety of neoplasms with a wide range of malignant potential,and it is often difficult to differentiate pancreatic tuberculosis mimicking cystic neoplasms from benign or malignant pancreatic cystic neoplasms. Non-surgical diagnosis of pancreatic tuberculosis is inconclusive and continues to be a challenge in many cases. If so,then laparotomy should be employed to establish the diagnosis. Therefore, pancreatic tuberculosis should be kept in mind during the differential diagnosis of solitary cystic masses in the pancreas. We report a patient who had solitary pancreatic tuberculosis masquerading as pancreatic serous cystadenoma.

    BACKGROUND:The role of endoscopic retrograde cholangiopancreatography (ERCP) in the management of acute pancreatitis has evolved over years since its introduction in 1968. Its importance in diagnosing the etiology of pancreatitis has steadily declined with the advent of less invasive diagnostic tools. The therapeutic implications of ERCP in acute pancreatitis are many fold and are directed towards management of known etiological factors or its related complications. This article highlights the current status of ERCP in acute pancreatitis. DATA SOURCES:An English literature search using PubMed database was conducted on ERCP in acute pancreatitis, the etiologies and complications of pancreatitis amenable to endotherapy and other related subjects, which were reviewed. RESULTS: ERCP serves as a primary therapeutic modality for management of biliary pancreatitis in speciifc situations, pancreatitis due to microlithiasis, speciifc types of sphincter of Oddi dysfunction, pancreas divisum, ascariasis and malignancy. In recurrent acute pancreatitis and smoldering pancreatitis it has a deifnite therapeutic utility. Complications of acute pancreatitis including pancreatic-duct disruptions or leaks, benign pancreatic-lfuid collections and pancreatic necrosis can be beneifcially dealt with. Intraductal ultrasound and pancreatoscopy during ERCP are useful in detecting pancreatic malignancy. CONCLUSIONS:The role of ERCP in acute pancreatitis is predominantly therapeutic and occasionally diagnostic. Its role in the management continues to evolve and advanced invasive procedures should be undertaken only in centers dedicated to pancreatic care.

    Full Text Available Extra-abdominal complications of pancreatitis such as pancreaticopleural fistulae are rare. A pancreaticopleural fistula occurs when inflammation of the pancreas and pancreatic ductal disruption lead to leakage of secretions through a fistulous tract into the thorax. The underlying aetiology in the majority of cases is alcohol-induced chronic pancreatitis. The diagnosis is often delayed given that the majority of patients present with pulmonary symptoms and frequently have large, persistent pleural effusions. The diagnosis is confirmed through imaging and the detection of significantly elevated amylase levels in the pleural exudate. Treatment options include somatostatin analogues, thoracocentesis, endoscopic retrograde cholangiopancreatography (ERCP with pancreatic duct stenting, and surgery. The authors present a case of pancreatic pseudocyst pleural fistula in a woman with gallstone pancreatitis presenting with recurrent pneumonias and bilateral pleural effusions.

  20. Pancreatic blood flow in experimental acute pancreatitis

    International Nuclear Information System (INIS)

    The etiology and pathogenesis of acute necrotizing hemorrhagic pancreatitis remain controversial. Recent work has suggested that an early fall in pancreatic blood flow, causing ischemia, may be the initiating factor. Using an established rat model of hemorrhagic pancreatitis and the fractional indicator distribution technique with 86RbCl, pancreatic blood flow and tissue perfusion have been measured at various times in the condition. Six groups of ten rats were studied: control sham operation and pancreatitis groups were sacrificed at 1, 6, and 24 hr. Pancreatic blood flow (% of cardiac output) and perfusion (blood flow/g tissue) were measured. Blood flow was increased by a maximum of 53% at 1 hr (P less than 0.001) and remained elevated for 24 hr, and perfusion was increased by a maximum of 70% (P less than 0.001) at 1 hr and remained elevated at 6 hr. Pancreatic perfusion declines after 6 hr due to increasing gland edema. The results demonstrate a significant increase in pancreatic blood flow and perfusion in experimentally induced acute pancreatitis, suggesting a primary inflammatory response, and refute the ischemic etiological theory

    Pancreatitis is defined as the inflammation of the pancreas and considered the most common pancreatic disease in children and adults. Imaging plays a significant role in the diagnosis, severity assessment, recognition of complications and guiding therapeutic interventions. In the setting of pancreatitis, wider availability and good image quality make multi-detector contrastenhanced computed tomography(MD-CECT) the most used imaging technique. However, magnetic resonance imaging(MRI) offers diagnostic capabilities similar to those of CT, with additional intrinsic advantages including lack of ionizing radiation and exquisite soft tissue characterization. This article reviews the proposed definitions of revised Atlanta classification for acute pancreatitis, illustrates a wide range of morphologic pancreatic parenchymal and associated peripancreatic changes for different types of acute pancreatitis. It also describes the spectrum of early and late chronic pancreatitis imaging findings and illustrates some of the less common types of chronic pancreatitis, with special emphasis on the role of CT and MRI.

  11. Pancreatitis. An update

    International Nuclear Information System (INIS)

    Acute and chronic pancreatitis are becoming increasingly more severe diseases in the western world with far-reaching consequences for the individual patient as well as the socioeconomic situation. This article gives an overview of the contribution of radiological imaging to the diagnostics and therapy of both forms of the disease. Acute pancreatitis can be subdivided into severe (20 %) and mild manifestations. The diagnostics should be performed with computed tomography (CT) or magnetic resonance imaging (MRI) for assessing necrosis or potential infections only in severe forms of pancreatitis. In chronic pancreatitis transabdominal ultrasound should initially be adequate for assessment of the pancreas. For the differential diagnosis between pancreatic carcinoma and chronic pancreatitis, MRI with magnetic resonance cholangiopancreatography (MRCP) followed by an endoscopic ultrasound-guided fine needle aspiration is the method of choice. For the primary diagnosis for acute and chronic pancreatitis ultrasound examination is the modality of first choice followed by radiological CT and MRI with MRCP examinations. (orig.)

  12. Therapy of pancreatic cancer

    International Nuclear Information System (INIS)

    Pancreatic cancer remains one of the most difficult diseases to cure. Japan pancreas society guidelines for management of pancreatic cancer indicate therapeutic algorithm according to the clinical stage. For locally limited pancreatic cancer (cStage I, II, III in Japanese classification system), surgical resection is recommended, however prognosis is still poor. Major randomized controlled trials of resected pancreatic cancer indicates that adjuvant chemotherapy is superior to observation and gemcitabine is superior to 5-fluorouracil (FU). For locally advanced resectable pancreatic cancer (cStage IVa in Japanese classification system (JCS)), we perform neoadjuvant chemoradiotherapy. Phase I study established a recommended dose of 800 mg gemcitabine and radiation dose of 36 Gy. For locally advanced nonresectable pancreatic cancer (cStage IVa in JCS), chemoradiotherapy followed by chemotherapy is recommended. Although pancreatic cancer is chemotherapy resistant tumor, systemic chemotherapy is recommended for metastatic pancreatic cancer (cStage IVb in JCS). Single-agent gemcitabine is the standard first line agent for the treatment of advanced pancreatic cancer. Meta-analysis of chemotherapy showed possibility of survival benefit of gemcitabine combination chemotherapy over gemcitabine alone. We hope gemcitabine combination chemotherapy or molecular targeted therapy will improve prognosis of pancreatic cancer in the future. (author)

  3. Pancreatic exocrine insufficiency after pancreatic surgery.

    Science.gov (United States)

    Goess, Ruediger; Ceyhan, Güralp O; Friess, Helmut

    2016-06-01

    Pancreatic exocrine insufficiency is an often-underestimated complication following pancreatic surgery. After recent advances in managing acute postoperative complications the focus of current research is now shifting onto the long-term complications following pancreatectomy. Weight loss and steatorrhea as typical symptoms have high influence on the quality of life in the postoperative period. Malnutrition-related symptoms occur late and are often misinterpreted. Enzyme replacement therapy is more or less the only possible treatment option, even though not many controlled trials have been performed in this field. In this review we summarized the pathophysiology, diagnosis, risk factors and treatment options of exocrine insufficiency and focus mainly on patients with pancreaticoduodenectomy (classical Whipple), pylorus-preserving pancreaticoduodenectomy (ppWhipple) or distal pancreatectomy. Incidence of pancreatic exocrine insufficiency after surgery depends mainly on the initial diagnosis, the preoperative exocrine function and is associated with the extent of parenchyma resection. Diagnosing exocrine failure after surgery can be difficult and specific function tests are commonly not routinely performed. Starting and monitoring of enzyme replacement treatment is more based on clinical symptoms, than on objective markers. To improve the performance status of postsurgical patients it is important to consider pancreatic exocrine function as one aspect of quality of life. Further clinical trials should be initiated to gain more specific knowledge about the influence of the different pancreatic resections on pancreatic exocrine function to initialize proper treatment even before major clinical symptoms occur.

    The diagnosis of acute pancreatitis is based on clinical examination and basic laboratory tests. The main role of sonography in acute pancreatitis is to evaluate gallstones and small fluid collections. However, sonography is frequently difficult due to intestinal ileus related to pancreatitis. CT is indicated early in the clinical course of acute severe pancreatitis when the diagnosis is uncertain or when complications such as abscess, hemorrhage, or necrosis, are suspected. In addition, CT may be used to assess the prognosis and follow-up of patients. (authors). 20 refs., 12 figs., 4 tabs.

  5. Focal pancreatic enlargement: differentiation between pancreatic adenocarcinoma and focal pancreatitis on CT and ERCP

    International Nuclear Information System (INIS)

    To differentiate the pancreatic adenocarcinoma from focal pancreatitis on CT and ERCP in cases of focal pancreatic enlargement. We analysed CT findings of 66 patients of pancreatic adenocarcinoma (n = 45) or focal pancreatitis (n = 21) with respect to size, density, calcification, pancreatic or biliary duct dilatation, fat plane obliteration around the vessels, direction of retroperitoneal extension, lymphadenopathy, pseudocyst formation and atrophy of pancreas. ERCP available in 48 patients were analysed in respect to morphologic appearance of CBD and pancreatic duct, and distance between the two ducts. The patients in focal pancreatitis were younger with more common history of alcohol drinking. There was no statistical difference in calcifications of the mass (18% in the adenocarcinoma, 33% in the focal pancreatitis), but a tendency of denser, larger number of calcifications was noted in focal pancreatitis. The finding of fat plane obliteration around the vessels were more common in pancreatic adenocarcinoma, and fascial thickenings were more prominent in focal pancreatitis, although not statistically significant. On ERCP, there were no differential points of CBD, pancreatic duct morphology, but distance between the two ducts at the lesion center was more wider in focal pancreatitis. Differentiating focal pancreatitis from pancreatic adenocarcinoma is difficult. However, we should consider the possibility of focal pancreatitis in cases of patients with young age, having alcoholic history in association with CT findings of large numbers of and dense calcifications, and ERCP findings of prominent separation of two duct at the lesion center

    The role of endoscopic therapy in the management of pancreatic diseases is continuously evolving; at present most pathological conditions of the pancreas are successfully treated by endoscopic retrograde cholangiopancreatography (ERCP) or endoscopic ultrasound (EUS),or both. Endoscopic placement of stents has played and still plays a major role in the treatment of chronic pancreatitis, pseudocysts, pancreas divisum, main pancreatic duct injuries, pancreatic fistulae, complications of acute pancreatitis, recurrent idiopathic pancreatitis,and in the prevention of post-ERCP pancreatitis. These stents are currently routinely placed to reduce intraductal hypertension, bypass obstructing stones, restore lumen patency in cases with dominant, symptomatic strictures,seal main pancreatic duct disruption, drain pseudocysts or fluid collections, treat symptomatic major or minor papilla sphincter stenosis, and prevent procedure-induced acute pancreatitis. The present review aims at updating and discussing techniques, indications, and results of endoscopic pancreatic duct stent placement in acute and chronic inflammatory diseases of the pancreas.

  12. Imaging of pancreatitis

    International Nuclear Information System (INIS)

    Full text: Acute pancreatitis (AP) is an acute inflammatory process of the pancreas with variable involvement of peripancreatic tissues or remote organ systems. Mild AP accounts for 75-80% of the cases and it is characterized by interstitial oedema, absent or minimal organ dysfunction, lack of complications and, usually, uneventful recovery. Severe AP is characterized by pancreatic necrosis, protracted clinical course, high incidence of complications, and high mortality rate. The diagnosis of acute pancreatitis (AP) is generally based on clinical and laboratory findings. The role of imaging is to confirm diagnosis, to assess disease severity - especially by detecting pancreatic necrosis-, to reveal complications of the disease and to guide interventions). Contrast- enhanced multidetector CT is the current 'gold standard' imaging modality in the evaluation of patients with AP. The spectrum of findings seen on CT ranges from a normal appearance to diffuse pancreatic enlargement with poorly defined pancreatic contour and heterogeneous attenuation. Stranding of the fat surrounding the pancreas and fluid collections in the anterior pararenal space, the peritoneal cavity or elsewhere, acquiring the form of the anatomic space where they are developed, may also be disclosed. Lack of pancreatic parenchyma enhancement is indicative of the presence of pancreatic necrosis. CT may reveal biliary tract calculi, calcifications in patients with AP combined with chronic pancreatitis- and air in an inflamed pancreas. Pancreatic abscess is usually seen on CT as a focal low attenuation area with a thick wall that may exhibit enhancement following i.v. contrast media administration. Haemorrhage, pseudoaneurysms, renal and splenic parenchyma complications can also be demonstrated by CT. Balthazar et.al have developed CT classification and severity scores based on the presence of fluid collections and pancreatic necrosis. These scores correlate with the incidence of morbidity and

    Full Text Available There is no specific treatment for acute pancreatitis. Majority of patients with acute pancreatitis respond to medical therapy. Supportive measures and close observations represent the cornerstone of the medical therapy. Failure to respond to medical treatment may indicate choledocholithiasis or infected necrosis. Endoscopic papillotomy with stone retrieval is beneficial in patients with severe biliary pancreatitis. Image-guided fine needle aspiration and bacteriological examination of aspirate is reliable in detecting infection and deliniating causative pathogen. Surgical debridement is the method of choice for treatment of infected necrosis. In contrast, in pancreatic abscess, surgery is preserved for those, who do not respond to percutaneous drainage combined with antibiotics. The benefit of antisecretory and antiproteolytic agents is debatable. A combination of antioxidants, calcium channel antagonists and antibiotics may play a major role in the treatment of acute pancreatitis in the future.

    Recent advances in understanding of pancreatitis and advances in technology have uncovered the veils of idiopathic pancreatitis to a point where a thorough history and judicious use of diagnostic techniques elucidate the cause in over 80% of cases. This review examines the multitude of etiologies of what were once labeled idiopathic pancreatitis and provides the current evidence on each. This review begins with a background review of the current epidemiology of idiopathic pancreatitis prior to discussion of various etiologies. Etiologies of medications, infections, toxins,autoimmune disorders, vascular causes, and anatomic and functional causes are explored in detail. We conclude with management of true idiopathic pancreatitis and a summary of the various etiologic agents. Throughout this review, areas of controversies are highlighted.

    2002-09-01

    Acute pancreatitis develops immediately after the causative impulse, while chronic pancreatitis develops after the long-term action of the noxious agent. A typical representative of acute pancreatitis is biliary pancreatitis, chronic pancreatitis develops in alcoholism and has a long latency. As alcoholic pancreatitis is manifested at first as a rule by a potent attack, it is classified in this stage as acute pancreatitis. The most frequent etiological factors in our civilization are thus cholelithiasis and alcoholism (both account for 20-50% in different studies). The assumed pathogenetic principles in acute biliary pancreatitis are the common canal of both efferent ducts above the obturated papilla, duodenopancreatic reflux and intrapancreatic hypertension. A detailed interpretation is however lacking. The pathogenesis of alcoholic pancreatitis is more complicated. Among others some part is played by changes in the calcium concentration and fusion of cellular membranes. Idiopathic pancreatitis occurs in up to 10%, part of the are due to undiagnosed alcoholism and cholelithiasis. Other etiologies are exceptional. Similarly as in cholelithiasis pancreatitis develops also during other pathological processes in the area of the papilla of Vater such as dysfunction of the sphincter of Oddi, ampulloma and juxtapapillary diverticulum, it is however usually mild. The incidence of postoperative pancreatitis is declining. Its lethality is 30% and the diagnosis is difficult. In the pathogenesis changes of the ion concentration are involved, hypoxia and mechanical disorders of the integrity of the gland. Pancreatitis develops in association with other infections--frequently in mumps, rarely in hepatitis, tuberculosis, typhoid and mycoses. Viral pancreatitis is usually mild. In parasitoses pancreatitis develops due to a block of the papilla Vateri. In hyperparathyroidism chronic pancreatitis is more likely to develop, recent data are lacking. As to dyslipoproteinaemias

    Acute pancreatitis (AP) is a rare event in pregnancy,occurring in approximately 3 in 10 000 pregnancies.The spectrum of AP in pregnancy ranges from mild pancreatitis to serious pancreatitis associated with necrosis, abscesses, pseudocysts and multiple organ dysfunction syndromes. Pregnancy related hematological and biochemical alterations influence the interpretation of diagnostic tests and assessment of severity of AP. As in any other disease associated with pregnancy, AP is associated with greater concerns as it deals with two lives rather than just one as in the nonpregnant population. The recent advances in clinical gastroenterology have improved the early diagnosis and effective management of biliary pancreatitis. Diagnostic studies such as endoscopic ultrasound,magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography and therapeutic modalities that include endoscopic sphincterotomy, biliary stenting, common bile duct stone extraction and laparoscopic cholecystectomy are major milestones in gastroenterology. When properly managed AP in pregnancy does not carry a dismal prognosis as in the past.

    International Nuclear Information System (INIS)

    It is important to understand which pancreatic function tests are available and how to interpret them when evaluating patients with malabsorption. Available direct tests are the secretin stimulation test, the Lundh test meal, and measurement of serum or fecal enzymes. Indirect tests assess pancreatic exocrine function by measuring the effect of pancreatic secretion on various nutrients. These include triglycerides labeled with carbon 14, cobalamin labeled with cobalt 57 and cobalt 58, and para-aminobenzoic acid bound to a dipeptide. Of all these tests the secretin stimulation test is the most accurate and reliable if done by experienced personnel. However, the indirect tests are simpler to do and appear to be comparable to the secretin test at detecting pancreatic exocrine insufficiency. These indirect tests are becoming clinically available and clinicians should familiarize themselves with the strengths and weaknesses of each

    2010-10-01

    Full Text Available Pancreatic cancer is characterized by an often dramatic outcome (five year survival < 5% related to a late diagnosis and a lack of efficient therapy. Therefore, clinicians desperately need new biomarkers and new therapeutic tools to develop new efficient therapies. Mucins belong to an ever increasing family of O-glycoproteins. Secreted mucins are the main component of mucus protecting the epithelia whereas membrane-bound mucins are thought to play important biological roles in cell-cell and cell-matrix interactions, in cell signaling and in modulating biological properties of cancer cells. In this review, we will focus on the altered expression pattern of mucins in pancreatic cancer, from the early neoplastic lesion Pancreatic Intraepithelial Neoplasia (PanIN to invasive pancreatic carcinomas, and the molecular mechanisms (including genetic and epigenetic regulation and signaling pathways known to control their expression. Moreover, we will discuss the recent advances about the biology of both secreted and membrane-bound mucins and their key roles in pancreatic carcinogenesis and resistance to therapy. Finally, we will discuss exciting opportunities that mucins offer as potential therapeutic targets in pancreatic cancer.

    Full Text Available Abstract Before the concept of autoimmune pancreatitis (AIP was established, this form of pancreatitis had been recognized as lymphoplasmacytic sclerosing pancreatitis or non-alcoholic duct destructive chronic pancreatitis based on unique histological features. With the discovery in 2001 that serum IgG4 concentrations are specifically elevated in AIP patients, this emerging entity has been more widely accepted. Classical cases of AIP are now called type 1 as another distinct subtype (type 2 AIP has been identified. Type 1 AIP, which accounts for 2% of chronic pancreatitis cases, predominantly affects adult males. Patients usually present with obstructive jaundice due to enlargement of the pancreatic head or thickening of the lower bile duct wall. Pancreatic cancer is the leading differential diagnosis for which serological, imaging, and histological examinations need to be considered. Serologically, an elevated level of IgG4 is the most sensitive and specific finding. Imaging features include irregular narrowing of the pancreatic duct, diffuse or focal enlargement of the pancreas, a peri-pancreatic capsule-like rim, and enhancement at the late phase of contrast-enhanced images. Biopsy or surgical specimens show diffuse lymphoplasmacytic infiltration containing many IgG4+ plasma cells, storiform fibrosis, and obliterative phlebitis. A dramatic response to steroid therapy is another characteristic, and serological or radiological effects are normally identified within the first 2 or 3 weeks. Type 1 AIP is estimated as a pancreatic manifestation of systemic IgG4-related disease based on the fact that synchronous or metachronous lesions can develop in multiple organs (e.g. bile duct, salivary/lacrimal glands, retroperitoneum, artery, lung, and kidney and those lesions are histologically identical irrespective of the organ of origin. Several potential autoantigens have been identified so far. A Th2-dominant immune reaction and the activation of

    Full Text Available Acute pancreatitis is a medical emergency. Alcohol and gallstones are the most common etiologies accounting for 60%-75% cases. Other important causes include postendoscopic retrograde cholangiopancreatography procedure, abdominal trauma, drug toxicity, various infections, autoimmune, ischemia, and hereditary causes. In about 15% of cases the cause remains unknown (idiopathic pancreatitis. Metabolic conditions giving rise to pancreatitis are less common, accounting for 5%-10% cases. The causes include hypertriglyceridemia, hypercalcemia, diabetes mellitus, porphyria, and Wilson′s disease. The episodes of pancreatitis tend to be more severe. In cases of metabolic pancreatitis, over and above the standard routine management of pancreatitis, careful management of the underlying metabolic abnormalities is of paramount importance. If not treated properly, it leads to recurrent life-threatening bouts of acute pancreatitis. We hereby review the pathogenesis and management of various causes of metabolic pancreatitis.

  1. Folate Deficiency in Chronic Pancreatitis

    Directory of Open Access Journals (Sweden)

    Gopalakrishna Rajesh

    2010-07-01

    Full Text Available Dear Sir, While there has been a spurt of interest in genetic alterations associated with pancreatitis in the past few years, interest in the role of environmental factors has largely focused on alcoholism and smoking with insufficient attention being paid to the contributions of nutritional deficiency, and the role of environmental toxins in the pathogenesis of pancreatitis. Braganza and Dormandy [1] argue convincingly about the role played by cytochrome P450 monooxygenases (especially CYP1A enzyme induction by xenobiotics and the resultant oxidative stress, as also the now increasingly recognized reductive stress posed by the metabolites in initiating pancreatic injury. Their article underlines the important part played by the deficiency of methyl and thiol molecules in different stages of the progression of pancreatic damage. Furthermore, they attempt to establish a link between environmental and genetic factors and bring in a holistic view on the etiopathogenesis of chronic pancreatitis. We have recently demonstrated lower plasma methionine levels in two cohorts of chronic pancreatitis patients; one of tropical chronic pancreatitis and the other, of alcoholic chronic pancreatitis as compared to healthy controls [2] which suggests that deficiency of methyl groups may be a factor in various forms of pancreatitis. Similarly, we have shown lower red cell glutathione levels in chronic pancreatitis patients with tropical chronic pancreatitis and alcoholic chronic pancreatitis, indicating deficiency of thiol molecules. In addition, we have demonstrated significantly higher levels of plasma total homocysteine in chronic pancreatitis patients than in healthy controls. Moreover, our study has shown that there is a deficiency of red cell folate in the majority of chronic pancreatitis patients, more so in tropical chronic pancreatitis; and that folate deficiency appeared to be the key factor in hyperhomocysteinemia in chronic pancreatitis patients

    The pancreas functions as the main factory for digestive enzymes and therefore enables food utilisation. Pancreatic exocrine insufficiency, partial or complete loss of digestive enzyme synthesis, occurs primarily in disorders directly affecting pancreatic tissue integrity. However, other disorders of the gastrointestinal tract, such as coeliac disease, inflammatory bowel disease, Zollinger-Ellison syndrome or gastric resection can either mimic or cause pancreatic exocrine insufficiency. The overt clinical symptoms of pancreatic exocrine insufficiency are steatorrhoea and maldigestion, which frequently become apparent in advanced stages. Several direct and indirect function tests are available for assessment of pancreatic function but until today diagnosis of excretory insufficiency is difficult as in mild impairment clinically available function tests show limitations of diagnostic accuracy. This review focuses on diagnosis of pancreatic exocrine insufficiency in pancreatic and non-pancreatic disorders. PMID:19505669

    Full Text Available Drugs account for 1-2% of all cases of pancreatitis. A 58-year-old man was prescribed atorvastatin 10 mg for 6 months for hyperlipidemia. He developed acute abdominal pain and vomiting with epigastric tenderness. Serum lipase and CT scan of the patient suggested the presence of acute pancreatitis. The patient was hospitalized; atorvastatin was stopped and treated symptomatically. He recovered completely within 10 days of drug withdrawal. The causality of the adverse drug reaction according to Naranjo and WHO-UMC Scale was probable. The exact mechanism of pancreatitis due to atorvastatin is not known. It may be a class effect of HMG CoA reductase inhibitors as it had been reported with other statins too. The definite causal relationship is difficult to establish, as rechallenge with the suspected drug was not done due to ethical consideration.

    Drugs are thought to be a rare cause for acute pancreatitis; however 525 different drugs are listed in the World Health Organization (WHO) database suspected to cause acute pancreatitis as a side effect. Many of them are widely used to treat highly prevalent diseases. The true incidence is not entirely clear since only few systematic population based studies exist. The majority of the available data are derived from case reports or case control studies. Furthermore, the causality for many of these drugs remains elusive and for only 31 of these 525 dugs a definite causality was established. Definite proof for causality is defined by the WHO classification if symptoms reoccur upon rechallenge.In the actual algorithm the diagnosis is confirmed if no other cause of acute pancreatitis can be detected, and the patient is taking one of the suspected drugs.

    Full Text Available Extranodal non-Hodgkin’s lymphomas (NHLs represent up to 30-40% of all NHL cases. The gastrointestinal tract is the most commonly involved extranodal site; accounting for about half of such cases [1]. Stomach and the small intestine constitute the most common gastrointestinal sites. Secondary invasion of the pancreas from contiguous, retroperitoneal lymph node disease is the prevalent mode of involvement. Secondary involvement of the pancreas from the duodenum or adjacent peripancreatic lymphadenopathy is well-known. Primary pancreatic lymphoma (PPL is an extremely rare disease [2]. PPL can present as an isolated mass mimicking pancreatic carcinoma. However, unlike carcinomas, PPL are potentially treatable [3].

    This article presents current MR imaging techniques for the pancreas, and review a spectrum of MR imaging features of various pancreatic diseases. These include: 1) congenital anomalies such as anomalous union of pancreatobiliary ducts, divisum, and annular pancreas, 2) inflammatory diseases, including acute or chronic pancreatitis with complications, groove pancreatitis, and autoimmune pancreatitis, tumor-forming pancreatitis, 3) pancreatic neoplasms, including adenocarcinoma, islet cell tumors, and cystic neoplasms (microcystic adenoma, mucinous cystic neoplasms, and intraductal mucin-producing pancreatic tumor). Particular attention is paid to technical advances in MR imaging of the pancreas such as fat-suppression, MR pancreatography (single- or multi-slice HASTE), and thin-section 3D multiphasic contrast-enhanced dynamic sequences. Imaging characteristics that may lead to a specific diagnosis or narrow the differential diagnosis are also discussed.

Case report A 79-year-old woman who was treated with antituberculosis therapy for 5 weeks was admitted to our unit for pancreatitis. Usual etiologies of pancreatitis were eliminated. Because of vomiting, antituberculosis therapy was withdrawn and symptoms disappeared. Eight days later, the same treatment was reintroduced and the patient presented recurrent pancreatitis; thus, treatment was withheld again followed by disappearance of clinical and biological abnormalities. Two days later, a treatment without isoniazid was reintroduced and no recurrence of symptoms was observed. Conclusions We have experienced a case of isoniazid induced pancreatitis. This is a rare cause of pancreatitis but potentially fatal thus recognition of drug induced pancreatitis and definitive withdrawal of the drug is required.

    Chronic pancreatitis has long been thought to be mainly associated with immoderate alcohol consumption. The observation that only ∼10% of heavy drinkers develop chronic pancreatitis not only suggests that other environmental factors, such as tobacco smoke, are potent additional risk factors, but also that the genetic component of pancreatitis is more common than previously presumed. Either disease-causing or protective traits have been indentified for mutations in different trypsinogen genes, the gene for the trypsin inhibitor SPINK1, chymotrypsinogen C, and the cystic fibrosis transmembane conductance regulator (CFTR). Other factors that have been proposed to contribute to pancreatitis are obesity, diets high in animal protein and fat, as well as antioxidant deficiencies. For the development of pancreatic cancer, preexisting chronic pancreatitis, more prominently hereditary pancreatitis, is a risk factor. The data on environmental risk factors for pancreatic cancer are, with the notable exception of tobacco smoke, either sparse, unconfirmed or controversial. Obesity appears to increase the risk of pancreatic cancer in the West but not in Japan. Diets high in processed or red meat, diets low in fruits and vegetables, phytochemicals such as lycopene and flavonols, have been proposed and refuted as risk or protective factors in different trials. The best established and single most important risk factor for cancer as well as pancreatitis and the one to clearly avoid is tobacco smoke. PMID:21734390

    Morphology-based imaging modalities have replaced classical conventional nuclear medicine modalities for detection of liver or pancreatic lesions. With positron emission tomography and the glucose analog F-18 fluorodeoxyglucose (FDG), a sensitive and specific modality for the detection of hepatic metastases and extrahepatic tumor deposits from hepatocellular or pancreatic cancer is available. F-18 FDG PET can increase the accuracy of staging primary tumors of the liver or the pancreas, and can be used for response monitoring. Radiopharmaceuticals such as Ga-68 DOTATOC and F-18 DOPA allow the specific detection of neuroendocrine pancreatic tumors and their metastatic deposits. Hybrid scanners such as PET-CT integrate morphologic and metabolic information, and allow to increase the sensitivity and specificity of noninvasive imaging in many tumor entities. The development of specific radiopharmaceuticals and technical innovations such as SPECT-CT has increased the reliability of conventional scintigraphic imaging. This chapter focuses on the use of PET-CT in hepatobiliary and pancreatic cancers. PMID:21331938

    AIM: To investigate the markers of pancreatic diseases and provide basic data and experimental methods for the diagnosis of pancreatic diseases. METHODS: There were 15 patients in the present study, among whom 10 had pancreatic cancer and 5, chronic pancreatitis. In all patients, pancreatic cancer or chronic pancreatitis was located on the head of the p-a-ncreas. Pathology data of all pa tients was confirmed by biopsy and surgery. Among the 10 patients with pancreatic cancer, 3 people had a medical history of longterm alcohol consumption. Of 5 patients with chronic pancreatitis, 4 men suffered from alcoholic chronic pancreatitis. Pancreatic juice samples were obtained from patients by endoscopic retrograde cholangiopancreatography. Magnetic resonance spectroscopyn was performed on an 11.7-T scanner (Bruker DRX-500) using Call-Purcell-Meiboom-Gill pulse sequences. The parameters were as follows: spectral width, 15 KHz; time domain, 64 K; number of scans, 512; and acquisition time, 2.128 s. RESULTS: The main component of pancreatic juice included leucine, iso-leucine, valine, lactate, alanine, acetate, aspartate, lysine, glycine, threonine, tyrosine, histidine, tryptophan, and phenylalanine. On performing 1D 1H and 2D total correlation spectroscopy, we found a triplet peak at the chemical shift of 1.19 ppm, which only appeared in the spectra of pancreatic juice obtained from patients with alcoholic chronic pancreatitis. This triplet peak was considered the resonance of the methyl of ethoxy group, which may be associated with the metabolism of alcohol in the pancreas. CONCLUSION: The triplet peak, at the chemical shift of 1.19 ppm is likely to be the characteristic metabolite of alcoholic chronic pancreatitis.

  1. Acute pancreatitis: Etiology and common pathogenesis

    Institute of Scientific and Technical Information of China (English)

    2009-01-01

    Acute pancreatitis is an inflammatory disease of the pancreas. The etiology and pathogenesis of acute pancreatitis have been intensively investigated for centuries worldwide. Many causes of acute pancreatitis have been discovered, but the pathogenetic theories are controversial. The most common cause of acute pancreatitis is gallstone impacting the distal common bile-pancreatic duct. The majority of investigators accept that the main factors for acute billiary pancreatitis are pancreatic hyperstimulation and bile-pancreatic duct obstruction which increase pancreatic duct pressure and active trypsin reflux. Acute pancreatitis occurs when intracellular protective mechanisms to prevent trypsinogen activation or reduce trypsin activity are overwhelmed. However, little is known about the other acute pancreatitis. We hypothesize that acute biliary pancreatitis and other causes of acute pancreatitis possess a common pathogenesis. Pancreatic hyperstimulation and pancreatic duct obstruction increase pancreatic duct pressure, active trypsin reflux, and subsequent unregulated activation of trypsin within pancreatic acinar cells. Enzyme activation within the pancreas leads to auto-digestion of the gland and local inflammation. Once the hypothesis is confirmed, traditional therapeutic strategies against acute pancreatitis may be improved. Decompression of pancreatic duct pressure should be advocated in the treatment of acute pancreatitits which may greatly improve its outcome.

    Full Text Available Context Pancreatic cancer is the fourth leading cause of cancer mortality in the United States. Most of the patients are diagnosed in the metastatic staging. Consolidated risk factors include chronic pancreatitis, smoking and family history. Although controversial, diabetes mellitus has been increasingly associated with pancreatic cancer as a risk factor as opposed to just a manifestation of the disease. Biomarkers for early diagnosis of pancreatic cancer among diabetic patients and metformin as a biologic therapy for pancreatic cancer are herein discussed. Methods Review of the literature and evaluation of two Abstracts (#180 and #253 from the 2014 ASCO Gastrointestinal Cancers Symposium focusing on pancreatic adenocarcinoma and diabetes diagnosis and therapeutics. Results Abstract #180 discusses the role of metabolic biomarkers in the early diagnosis of pancreatic cancer among diabetic patients, especially recently diagnosed. Abstract #253 debates metformin as a candidate radiosensitizer for pancreatic cancer, although it fails to reject its null hypothesis. Conclusion Search for methods that can identify pancreatic cancer patients among new-onset diabetic patients could result in early diagnosis of this lethal disease. Metformin is a target therapy that increases median overall survival but is not a radiation sensitizer in patients with pancreatic cancer who present with diabetes.

  3. Acute pancreatitis: clinical vs. CT findings

    International Nuclear Information System (INIS)

    In a prospective study of 91 patients with acute pancreatitis, computed tomographic (CT) findings were correlated with the clinical type of acute pancreatitis. In acute edematous pancreatitis (63 patients; 16 with repeat CT), CT was normal (28%) or showed inflammation limited to the pancreas (61%). Phlegmonous changes were present in 11%, including one patient with focal pancreatic hemorrhage, indicating that clinically unsuspected hemorrhagic pancreatitis can occur. In acute necrotizing (hemorrhagic, suppurative) pancreatitis (nine patients; eight with repeat CT), no patient had a normal CT scan and 89% had phlegmonous changes. One patient had hemorrhagic pancreatitis and three had abscesses. In acute exacerbation of chronic pancreatitis (10 patients; three with repeat CT), there were pancreatic calcifications (70%), a focal mass (40%), and pancreatic ductal dilation (30%). On follow-up CT, the findings of acute pancreatitis did not always disappear with resolution of the clinical symptons. This was especialy true of phlegmonous pancreatitis, where the CT findings could persist for months

    Pancreatic cancer is highly chemoresistant. A major contributing factor is the characteristic extensive stromal or fibrotic reaction, which comprises up to 90% of the tumor volume. Over the last decade there has been intensive research into the role of the pro-fibrogenic pancreatic stellate cells (PSCs) and their interaction with pancreatic cancer cells. As a result of the significant alterations in the tumor microenvironment following activation of PSCs, tumor progression, and chemoresistanc...

    Groove pancreatitis is a rare form of segmental chronic pancreatitis that involves the anatomic space between the head of the pancreas, the duodenum, and the common bile duct. We report 2 cases of groove pancreatitis with pancreatic heterotopia in the minor papilla. Patients were a 44-year-old woman and a 47-year-old man. Both had a past history of alcohol consumption and presented with abdominal pain, vomiting, and weight loss caused by duodenal stenosis. Abdominal computed tomography revealed thickening of the duodenal wall and enlargement of the pancreatic head in both patients. In 1 patient, ultrasound endoscopy showed a dilated duct in the head of the pancreas. Pancreaticoduodenectomy was performed to rule out pancreatic adenocarcinoma and because of the severity of the symptoms. In both cases, gross and microscopic examinations showed fibrous scar of the groove area. The Santorini duct was dilated and contained protein plugs in both patients, with abscesses in 1 of them. In both cases, there were microscopic foci of heterotopic pancreas with mild fibrosis in the wall of the minor papilla. Groove pancreatitis is often diagnosed in middle-aged alcoholic men presenting with clinical symptoms caused by duodenal stenosis. The pathogenesis of this rare entity could be because of disturbance of the pancreatic secretion through the minor papilla. Pancreatitis in heterotopic pancreas located in the minor papilla and chronic consumption of alcohol seem to be important pathogenic factors. PMID:15841034

    Follicular pancreatitis is a recently described variant of chronic pancreatitis characterized clinically by the formation of a discrete pancreatic mass and histologically by the presence of florid lymphoid aggregates with reactive germinal centers. Our aim was to study the clinical and histologic features of follicular pancreatitis, as well as to critically examine potential overlap with autoimmune pancreatitis. Immunohistochemistry for Bcl-2, CD21, κ and λ light chains as well as IgG4 and IgG were performed. We found a total of 6 patients (male-female ratio, 2:1; mean age, 57 years) who fulfilled the diagnosis of follicular pancreatitis in our institutions. Four had an incidental diagnosis, while two presented with abdominal pain, fatigue, and elevated liver enzymes. On imaging, 3 patients had a discrete solid mass, whereas 2 cases showed a dilated main pancreatic duct, mimicking an intraductal pancreatic mucinous neoplasm on imaging. One patient had a lesion in the intra-pancreatic portion of the common bile duct. On histopathology, all cases showed numerous lymphoid follicles with Bcl-2-negative germinal centers either in a periductal or in a more diffuse (periductal and intra-parenchymal) fashion, but without attendant storiform fibrosis, obliterative phlebitis, or granulocytic epithelial lesions. IgG4-to-IgG ratio was <40% in 5 cases. A comparison cohort revealed germinal centers in 25% of type 1 autoimmune pancreatitis and 2% of type 2 autoimmune pancreatitis cases, but none were periductal in location. In conclusion, follicular pancreatitis, an under-recognized mimic of pancreatic neoplasms is characterized by intrapancreatic lymphoid follicles with reactive germinal centers. PMID:26563969

    1983-05-01

    In a review of over 300 CT scans of abdominal trauma, we encountered 13 patients with surgically proved pancreatic injuries. CT correctly diagnosed pancreatic fractures, contusions, or posttraumatic pseudocysts in 11 of these patients. There were two false positive and two false negative diagnoses. The CT diagnosis of pancreatic trauma may be difficult in selected patients who are scanned soon after injury. Acutely, the actual plane of a pancreatic fracture may be difficult to identify with CT, and the peripancreatic soft-tissue changes of traumatic pancreatitis are often subtle. Eight of 11 correctly diagnosed pancreatic injuries showed thickening of the left anterior renal fascia on CT scans. This sign should prompt a critical evaluation of the pancreas of the traumatized patient.

  14. Biliary scintigraphy in acute pancreatitis

    International Nuclear Information System (INIS)

    A prospective study was carried out in 60 patients to determine the efficacy of 99/sup m/Tc-PIPIDA scintigraphy in differentiating biliary pancreatitis from nonbiliary pancreatitis. Forty patients were classified as having biliary pancreatitis and 20 patients as having the nonbiliary type. Scintigraphic scans were divided into five main types according to the time to visualization of the gallbladder and the time to excretion of 99/sup m/Tc-PIPIDA into the intestinal tract. Normal scans were obtained in 95% of patients (19/20) with nonbiliary pancreatitis; 22.5% of patients (9/40) with biliary pancreatitis had normal scans. It is concluded that elevated amylase levels together with an abnormal biliary scan, as defined by the criteria presented here, indicate biliary pancreatitis, while a normal scan largely excludes such diagnosis

    Full Text Available CONTEXT: Carbamate insecticides are widely used in commercial agriculture and home gardening. A serious side effect of organophosphate and carbamate intoxication is the development of acute pancreatitis. CASE REPORT: A 36-year-old Caucasian woman was admitted to our hospital with cholinergic crisis and pancreatitis soon after the ingestion of a carbamate insecticide (carbofuran. An abdominal CT scan disclosed pancreatic necrosis with intrapancreatic fluid collection, consistent with the development of a pancreatic pseudocyst in a subsequent CT scan. No predisposing factor for pancreatitis was evident. Pseudocholinesterase levels returned to normal 7 days later and the patient was discharged in good physical condition one month after admission. DISCUSSION: Although acute pancreatitis is not infrequent after organophosphate intoxication, it is quite rare after carbamate ingestion and has not been previously reported after carbofuran intoxication.

  5. Pancreatic scintiphotography in diabetes mellitus

    International Nuclear Information System (INIS)

    Pancreatic scintiphotography was performed in 108 cases of patients with diabetes mellitus. Scintiphotos were taken at 30 min. after intravenous injection of approximately 200μCi of 75Se-selenomethionine using a Toshiba gamma camera. The relationship between the degree of pancreatic uptake of 75Se-selenomethionine and the types and duration of diabetes, vascular complications and the average range of fasting blood sugar levels were studied. In some cases, pancreatic scintiphotos were taken at 10, 30 and 50 min. after injection of 75Se-selenomethionine, and the degrees of the pancreatic uptake were compared on each time course. Only two out of 24 cases of insulin-dependent diabetics showed normal pancreatic scintiphotos. On the other hand, two out of 47 cases of mild diabetics treated with diet alone showed no uptake in pancreatic scintiphotos. There was a tendency toward abnormal pancreatic scintiphotos in chronic diabetics. Especially, of the 15 cases who had diabetes for more than eleven years, only one case showed a normal pancreatic scintiphoto. Abnormal pancreatic scintiphotos were found more frequently in the group of poorly controlled diabetics than in the group of well controlled diabetics. In cases showing normal pancreatic scintiphotos, diabetic retinopathy was less frequently found. Out of 36 cases which had sequential pancreatic scintiphotos, hypertension and/or arteriosclerosis were found more frequently in the 20 cases which showed a delay in reaching a plateau of the activity. However, the uptake in sequential pancreatic scintiphotos showed no definite correlation between diabetic retinopathy and other diabetic conditions. (auth.)

    The present article analyses the main presentations on acute pancreatitis at Digestive Disease Week 2015. Arterial pseudoaneurysm is an uncommon complication of acute pancreatitis (incidence 0.7%) and mortality from this cause is currently anecdotal. Diabetes mellitus has little impact on the clinical course of acute pancreatitis, unlike cirrhosis, which doubles the risk of mortality. Intake of unsaturated fat could be associated with an increased severity of acute pancreatitis and is a confounding factor in studies evaluating the relationship between obesity and morbidity and mortality. PET-CT (positron emission tomography-computed tomography) could be a non-invasive tool to detect infection of collections in acute pancreatitis. Peripancreatic fat necrosis is less frequent than pancreatic fat necrosis and is associated with a better clinical course. If the clinical course is poor, increasing the calibre of the percutaneous drains used in the treatment of infected necrosis can avoid surgery in 20% of patients. The use of low molecular-weight heparin in moderate or severe pancreatitis could be associated with a better clinical course, specifically with a lower incidence of necrosis. In acute recurrent pancreatitis, simvastatin is a promising drug for prophylaxis of new episodes of acute pancreatitis. Nutritional support through a nasogastric tube does not improve clinical course compared with oral nutrition. PMID:26520203

    A possible role for Helicobacter pylori(H. pylori) infec-tion in pancreatic diseases remains controversial. H. pylori infection with antral predomination leading to an increase in pancreatic bicarbonate output and induc-ing ductal epithelial cell proliferation could contribute to the development of pancreatic cancer via complex interactions with the ABO genotype, dietary and smok-ing habits and N-nitrosamine exposure of the host. Although the individual study data available so far is inconsistent, several meta-analyses have reported an increased risk for pancreatic cancer among H. pylori seropositive individuals. It has been suggested that H. pylori causes autoimmune pancreatitis due to molecu-lar mimicry between H. pylori a-carbonic anhydrase(a-CA) and human CA type Ⅱ, and between H. pylori plasminogen-binding protein and human ubiquitin-protein ligase E3 component n-recognin 2, enzymes that are highly expressed in the pancreatic ductal andacinar cells, respectively. Future studies involving large numbers of cases are needed in order to examine the role of H. pylori in autoimmune pancreatitis more fully. Considering the worldwide pancreatic cancer burden, as well as the association between autoimmune pan-creatitis and other autoimmune conditions, a complete elucidation of the role played by H. pylori in the gen-esis of such conditions could have a substantial impact on healthcare.

  8. Pancreatic and hepatobiliary cancer

    International Nuclear Information System (INIS)

    Although radical operations can cure resectable cancer of the pancreas or biliary tract, few patients present with resectable disease. Most patients with pancreatic cancer present with lesions in the head of the pancreas that have either spread beyond the local area by hematogenous or peritoneal routes or are technically unresectable because of the local extent of disease. For the latter group the main surgical options are palliative biliary bypass alone or in combination with elective gastroenterostomy. Carcinoma of the biliary tract (gallbladder or bile duct) is uncommon compared to other gastrointestinal malignancies and has a wide range of natural history. Until recently surgery was the only therapy considered in most patients even though most lesions were unresectable and only palliative procedures could be performed. If gains are to be made with the locally unresectable pancreatic or biliary tract lesions, they will have to come through treatment with radiation, chemotherapy, or a combination of both

    Aetiologic factors (gallstones, hyperlipidemia I-IV, hypertriglyceridaemia) make their occurrence, mainly, in the third trimester of gestation. Two cases of acute pancreatitis in pregnancy are described; in both cases patients referred healthy diet, no habit to smoke and no previous episode of pancreatitis. An obstructive pathology of biliary tract was the aetiologic factor. Vomiting, upper abdominal pain are aspecific symptoms that impose a differential diagnosis with acute appendicitis, cholecystitis and obstructive intestinal pathology. Laboratory data (elevated serum amylase and lipase levels) and ultrasonography carry out an accurate diagnosis. The management of acute pancreatitis is based on the use of symptomatic drugs, a low fat diet alternated to the parenteral nutrition when triglycerides levels are more than 28 mmol/L. Surgical therapy, used only in case of obstructive pathology of biliary tract, is optimally collected in the third trimester or immediately after postpartum. Our patients, treated only medically, delivered respectively at 38th and 40th week of gestation. Tempestivity of diagnosis and appropriate therapy permit to improve prognosis of a pathology that, although really associated with pregnancy, presents high maternal mortality (37%) cause of complications (shock, coagulopathy, acute respiratory insufficiency) and fetal (37.9%) by occurrence of preterm delivery.

    Pancreatic pseudocysts are a well-known complication of acute or chronic pancreatitis, with a higher incidence in the latter. Diagnosis is accomplished most often by computed tomographic scanning, by endoscopic retrograde cholangiopancreatography, or by ultrasound, and a rapid progress in the improvement of diagnostic tools enables detection with high sensitivity and specificity. Different strategies contribute to the treatment of pancreatic pseudocysts: endoscopic transpapillary or transmural drainage, percutaneous catheter drainage, or open surgery. The feasibility of endoscopic drainage is highly dependent on the anatomy and topography of the pseudocyst, but provides high success and low complication rates. Percutaneous drainage is used for infected pseudocysts. However, its usefulness in chronic pancreatitis-associated pseudocysts is questionable. Internal drainage and pseudocyst resection are frequently used as surgical approaches with a good overall outcome, but a somewhat higher morbidity and mortality compared with endoscopic intervention. We therefore conclude that pseudocyst treatment in chronic pancreatitis can be effectively achieved by both endoscopic and surgical means. This review entails publications referring to the classification of pancreatic pseudocysts, epidemiology, diagnostic tools, and therapeutic options for pancreatic pseudocysts. Only full articles were considered for the review. Based on a search in PubMed, the MeSH terms "pancreatic pseudocysts and classification," "diagnosis," and "endoscopic, percutaneous, and surgical treatment" were used either alone or in combination.

  16. Pancreatic polypepetide inhibits pancreatic enzyme secretion via a cholinergic pathway

    International Nuclear Information System (INIS)

    In rat pancreatic slices, rat pancreatic polypeptide (PP) or C-terminal hexapeptide of PP [PP-(31-36)] inhibited potassium-stimulated amylase release in a dose-dependent manner. The inhibition was unaffected by addition of hexamethonium but blocked by atropine. In contrast, PP-(31-36) did not have any effect on acetylcholine- or cholecystokinin octapeptide-stimulated amylase release. In addition, when pancreatic slices were incubated with [3H]choline, PP-(31-36) inhibited the potassium-evoked release of synthesized [3H]acetylcholine in a dose-dependent manner. The inhibitory action of PP was unaffected by adrenergic, dopaminergic, or opioid receptor antagonists. Thus PP inhibits pancreatic enzyme secretion via presynaptic modulation of acetylcholine release. This newly identified pathway provides a novel mechanism for hormonal inhibition of pancreatic enzyme secretion via modulation of the classic neurotransmitter function

  18. Possible Involvement of Pancreatic Fatty Infiltration in Pancreatic Carcinogenesis

    Directory of Open Access Journals (Sweden)

    2016-03-01

    Full Text Available Pancreatic cancer is difficult to diagnose in its early stage and is one of the most lethal human cancers. Thus, it is important to clarify its major risk factors, predictive factors and etiology. Here, we focus on fatty infiltration of the pancreas and suggest that it could be a risk factor for pancreatic cancer. Fatty infiltration of the pancreas is observed as ectopic adipocytes infiltrating the pancreatic tissue and is positively correlated with obesity and the prevalence of diabetes mellitus, which are risk factors for pancreatic cancer. However, whether fatty infiltration is a major risk factor for pancreatic cancer has not been established. Recent clinical studies show there is a positive correlation between fatty infiltration of the pancreas and pancreatic precancerous lesions or ductal adenocarcinomas. Animal experimental studies also show an association between fatty infiltration of the pancreas and pancreatic precancerous lesions or ductal adenocarcinomas development. Syrian golden hamsters, which are sensitive to chemical carcinogens in the pancreas, develop fatty infiltration of the pancreas with age. The combination of a high-fat diet and a chemical carcinogen that induces a K-ras mutation increases the severity of fatty infiltration of the pancreas. Thus, fatty infiltration of the pancreas is suggested to promote pancreatic carcinogenesis via a K-ras activating mutation. It is assumed that increased expression of adipokines and of inflammatory and proliferation-associated factors elicited by fatty infiltration of the pancreas may contribute to pancreatic precancerous lesions or ductal adenocarcinomas development. Accumulating evidence suggests that in addition to suppression of Ras activation, methods to modulate fatty infiltration in the pancreas can be considered as a strategy for preventing pancreatic cancer.

    Full Text Available Context: Groove pancreatitis is a rare form of chronic pancreatitis affecting the "groove" of the pancreas among the pancreatic head, duodenum, and common bile duct. The exact cause is unknown, although there are associations with long-term alcohol abuse, smoking, peptic ulcer disease, heterotopic pancreas, gastric resection, biliary disease, and anatomical or functional obstruction of the minor papilla. The diagnosis can be challenging. Endoscopic ultrasound (EUS and magnetic resonance cholangiopancreatography are the preferred imaging modalities. The treatment of choice is conservative although surgical intervention can sometimes be required. Case Report: A 57-year-old male with a history of human immunodeficiency virus and hepatitis B presented with 4 days of epigastric pain. Abdominal exam revealed absent bowel sounds and epigastric tenderness. He had a creatinine of 1.72 mg/dL, potassium of 2.9 mmol/L, and a normal lipase level of 86 U/L. Liver enzymes and total bilirubin were normal. Computed tomography abdomen showed high-grade obstruction of the second portion of the duodenum without any obvious mass. An esophagogastroduodenoscopy showed a mass at the duodenal bulb causing luminal narrowing, with biopsies negative for malignancy. Magnetic resonance imaging revealed a mass in the region of the pancreatic head and descending duodenum. EUS revealed a 3 cm mass in the region of pancreatic head with irregular borders and no vascular invasion. Fine needle aspiration (FNA was nondiagnostic. The patient then underwent a Whipple′s procedure. Pathology of these specimens was negative for malignancy but was consistent with para-duodenal or groove pancreatitis. Conclusion: The low incidence of groove pancreatitis is partly due to lack of familiarity with the disease. Groove pancreatitis should be considered in the differential for patients presenting with pancreatic head lesions and no cholestatic jaundice, especially when a duodenal obstruction

  20. Beer and its Non-Alcoholic Compounds: Role in Pancreatic Exocrine Secretion, Alcoholic Pancreatitis and Pancreatic Carcinoma

    2010-03-01

    Full Text Available : In this article we provide an overview of the newest data concerning the effect of non-alcoholic constituents of alcoholic beverages, especially of beer, on pancreatic secretion, and their possible role in alcoholic pancreatitis and pancreatic carcinoma. The data indicate that non-alcoholic constituents of beer stimulate pancreatic enzyme secretion in humans and rats, at least in part, by direct action on pancreatic acinar cells. Some non-alcoholic compounds of beer, such as quercetin, resveratrol, ellagic acid or catechins, have been shown to be protective against experimentally induced pancreatitis by inhibiting pancreatic secretion, stellate cell activation or by reducing oxidative stress. Quercetin, ellagic acid and resveratrol also show anti-carcinogenic potential in vitro and in vivo. However, beer contains many more non-alcoholic ingredients. Their relevance in beer-induced functional alterations of pancreatic cells leading to pancreatitis and pancreatic cancer in humans needs to be further evaluated.

  3. Diet and Pancreatic Cancer Prevention

    Full Text Available Pancreatic cancer is without any doubt the malignancy with the poorest prognosis and the lowest survival rate. This highly aggressive disease is rarely diagnosed at an early stage and difficult to treat due to its resistance to radiotherapy and chemotherapy. Therefore, there is an urgent need to clarify the causes responsible for pancreatic cancer and to identify preventive strategies to reduce its incidence in the population. Some circumstances, such as smoking habits, being overweight and diabetes, have been identified as potentially predisposing factors to pancreatic cancer, suggesting that diet might play a role. A diet low in fat and sugars, together with a healthy lifestyle, regular exercise, weight reduction and not smoking, may contribute to prevent pancreatic cancer and many other cancer types. In addition, increasing evidence suggests that some food may have chemo preventive properties. Indeed, a high dietary intake of fresh fruit and vegetables has been shown to reduce the risk of developing pancreatic cancer, and recent epidemiological studies have associated nut consumption with a protective effect against it. Therefore, diet could have an impact on the development of pancreatic cancer and further investigations are needed to assess the potential chemo preventive role of specific foods against this disease. This review summarizes the key evidence for the role of dietary habits and their effect on pancreatic cancer and focuses on possible mechanisms for the association between diet and risk of pancreatic cancer.

    Acute pancreatitis is not infrequent after allogenic marrow transplantation. Several causes can predispose to pancreatitis, including Graft-Versus-Host Disease (GVHD), a condition which is probably underestimated. In the literature, few description of pancreatic GVHD can be found. Pancreatic GVHD diagnosis can be difficult if pancreatic involvement occurs without other typical manifestations of GVHD. We report the case of a woman, 54 years old, suffering from prolonged, painful pancreatitis two months after allogenic bone marrow transplantation for acute myeloid leucemia. Pancreatic GVHD diagnosis was performed after five weeks on duodenal biopsies despite the absence of diarrheoa. The patient dramatically improved within few days on corticosteroids. PMID:18378104

    Pancreatic cancer is one of the most lethal of human malignancies ranking 4th among cancer-related death in the western world and in the United States,and potent therapeutic options are lacking.Although during the last few years there have been important advances in the understanding of the molecular events responsible for the development of pancreatic cancer,currently specific mechanisms of treatment resistance remain poorly understood and new effective systemic drugs need to be developed and probed.In vivo models to study pancreatic cancer and approach this issue remain limited and present different molecular features that must be considered in the studies depending on the purpose to fit special research themes.In the last few years,several genetically engineered mouse models of pancreatic exocrine neoplasia have been developed.These models mimic the disease as they reproduce genetic alterations implicated in the progression of pancreatic cancer.Genetic alterations such as activating mutations in KRas,or TGFb and/or inactivation of tumoral suppressors such as p53,INK4A/ARF BRCA2 and Smad4 are the most common drivers to pancreatic carcinogenesis and have been used to create transgenic mice.These mouse models have a spectrum of pathologic changes,from pancreatic intraepithelial neoplasia to lesions that progress histologically culminating in fully invasive and metastatic disease and represent the most useful preclinical model system.These models can characterize the cellular and molecular pathology of pancreatic neoplasia and cancer and constitute the best tool to investigate new therapeutic approaches,chemopreventive and/or anticancer treatments.Here,we review and update the current mouse models that reproduce different stages of human pancreatic ductal adenocarcinoma and will have clinical relevance in future pancreatic cancer developments.

    International Nuclear Information System (INIS)

    The classification of accumulative patterns with the pancreatic scintigram findings of chronic pancreatitis and carcinoma of the pancreas were compared with endoscopic retrograde pancreatography (ERP) findings and Pancreozymin-Secretin test (P-S test). I) The frequency of pancreatic cancer was 93%, whilst, the chronic pancreatitis was 88% in the abnormal pancreatic scintigram. II) In the scintigram the type II (localyzed defect shadows) of pancreatic cancer was comparatively high and it is proportional to evidence. derived from ERP. Localized diagnostic certainty is helpful, although the two tests are related. The P-S test is only restricted to the carcinoma of head, whilst, scintigram is more useful to detect the carcinoma of the body and tail of the pancreas. III) As for the chronic pancreatitis, there are various accumulative patterns. This is resemblance to that of ERP findings, but in the P-S normal test, it showed discrepancy in part of the result. Particularly, in the type I (slightly generalized low uptake with density silhouette) and type II. Therefore in order to obtain an accurate diagnosis, it is essential to have both the P-S test and scintigram. (author)

    AIM: To study the feature of pancreatic microcirculatoryimpairment, especially the initial changes, in caerulein-induced experimental acute pancreatitis (AP).METHODS: The pancreatic microcirculation of caerulein-induced AP model was studied by intravital fluorescencemicroscopy with FITC-labeled erythrocytes (FITC-RBC),scanning electron microscopy of vascular corrosion casts,and light microscopy of Chinese ink-injected/cleared tissues.RESULTS: Animals in caerulein-treated group showedhyperamylemia (× 2), pancreatic oedema, infiltration ofinflammatory cells in pancreas. Constrictions of intralobulararteriolar sphincters, presence of vacuoles in all layers ofsphincter, and gross irregularity in capillary network of aciniwere found in the AP specimens. The decrease of pancreaticcapillary blood flow (0.34±0.10 nl @ min-1 vs0.910.06 nl @rain-1 of control, P<0.001), reduction of functional capillarydensity(277± 13 cm-1 vs349±8 cm-1 of control, P<0.001),and irregular intermittent perfusion were observed incaerulein-induced groups.CONCLUSION: Impairment and constriction of pancreaticintralobular arteriolar sphincter are the initial microcirculatorylesions in the early phase of acute pancreatitis, and play akey role in the pancreatic ischaemia and pancreaticmicrovascular failure in acute pancreatitis.

    Pancreatic duct stones are a common complication during the natural course of chronic pancreatitis and often contribute to additional pain and pancreatitis. Abdominal pain, one of the major symptoms of chronic pancreatitis, is believed to be caused in part by obstruction of the pancreatic duct system (by stones or strictures) resulting in increasing intraductal pressure and parenchymal ischemia. Pancreatic stones can be managed by surgery, endoscopy, or extracorporeal shock wave lithotripsy. ...

    2009-09-01

    Full Text Available Abstract Background No formulation of exogenous insulin available to date has yet been able to mimic the physiological nictemeral rhythms of this hormone, and despite all engineering advancements, the theoretical proposal of developing a mechanical replacement for pancreatic β cell still has not been reached. Thus, the replacement of β cells through pancreas and pancreatic islet transplantation are the only concrete alternatives for re-establishing the endogenous insulin secretion in type 1 diabetic patients. Since only 1 to 1.5% of the pancreatic mass corresponds to endocrine tissue, pancreatic islets transplantation arises as a natural alternative. Data from the International Islet Transplant Registry (ITR from 1983 to December 2000 document a total of 493 transplants performed around the world, with progressively worse rates of post-transplant insulin independence. In 2000, the "Edmonton Protocol" introduced several modifications to the transplantation procedure, such as the use of a steroid-free immunosuppression regimen and transplantation of a mean islet mass of 11,000 islet equivalents per kilogram, which significantly improved 1-year outcomes. Although the results of a 5-year follow-up in 65 patients demonstrated improvement in glycemic instability in a significant portion of them, only 7.5% of the patients have reached insulin independence, indicating the need of further advances in the preservation of the function of transplanted islet. In addition to the scarcity of organs available for transplantation, islets transplantation still faces major challenges, specially those related to cell loss during the process of islet isolation and the losses related to the graft site, apoptosis, allorejection, autoimmunity, and immunosuppression. The main strategies to optimize islet transplantation aim at improving all these aspects. Conclusion Human islet transplantation should be regarded as an intervention that can decrease the frequency of

    A 25-year-old caucasian lady presented to the Accident & Emergency department complaining of acute onset severe epigastric pain radiating through to the back with associated nausea and vomiting. A diagnosis of acute pancreatitis was made. Symptoms commenced after the third dose of Metronidazole therapy prescribed for a recurrent periodontal abscess. The patient described a similar episode 10 months previously. On neither occasion were any other medications being taken, there was no history of alcohol abuse and no other gastro-intestinal aetiology could be identified on imaging. Symptoms resolved quickly upon discontinuation of the antibiotic agent. We conclude therefore that Metronidazole can reasonably be identified as the only potential causative agent.

    Functionally, the pancreas consists of two types of tissues: exocrine and endocrine. Exocrine pancreatic disorders mainly involve acute and chronic pancreatitis. Acute pancreatitis typically is benign, while chronic pancreatitis is considered a risk factor for developing pancreatic cancer. Pancreatic carcinoma is the fourth leading cause of cancer related deaths worldwide. Most pancreatic cancers develop in the exocrine tissues. Endocrine pancreatic tumors are more uncommon, and typically are less aggressive than exocrine tumors. However, the endocrine pancreatic disorder, diabetes, is a dominant cause of morbidity and mortality. Importantly, different growth factors and their receptors play critical roles in pancreatic pathogenesis. Hence, an improved understanding of how various growth factors affect pancreatitis and pancreatic carcinoma is necessary to determine appropriate treatment. This chapter describes the role of different growth factors such as vascular endothelial growth factor (VEGF), insulin-like growth factor (IGF), platelet derived growth factor (PDGF), fibroblast growth factor (FGF), epidermal growth factor (EGF), and transforming growth factor (TGF) in various pancreatic pathophysiologies. Finally, the crosstalk between different growth factor axes and their respective signaling mechanisms, which are involved in pancreatitis and pancreatic carcinoma, are also discussed.

    To describe the spiral CT findings of groove pancreatitis, a little known entity, and to review its differential diagnosis. We present 8 cases of groove pancreatitis. or pancreatitis affecting the groove between pancreatic head, duodenum and common bile duct, all studied with spiral CT. For two cases, in which were performed cephalic duodenopancreatectomies, anatomopathological correlations were available. In the other 6 cases, radiological follow-ups of anywhere between 5 and 36 months were utilized. In all eight cases, spiral CT showed expansion and increasing density of lipids within the groove with poor contrast enhancement indicative of the fibrous nature of this pathology, and associated with cystic areas in its interior and/or the duodenal wall. the pancreatic head was unaffected in pure forms of groove pancreatitis, and hypodense areas were observed in zones of cephalic segmental enhancement. Knowledge of this little known form of chronic pancreatitis, and the radiological findings that permit its diagnosis are important for the radiologist since its differential diagnosis includes neoplasia of the peri-ampullary region.

    Full Text Available Drug absorption in patients with chronic pancreatitis might be affected by the pathophysiology of the disease. The exocrine pancreatic insufficiency is associated with changes in gastrointestinal intraluminal pH, motility disorder, bacterial overgrowth and changed pancreatic gland secretion. Together these factors can result in malabsorption and may also affect the efficacy of pharmacological intervention. The lifestyle of chronic pancreatitis patients may also contribute to gastrointestinal changes. Many patients limit their food intake because of the pain caused by eating and in some cases food intake is more or less substituted with alcohol, tobacco and coffee. Alcohol and drug interaction are known to influence the pharmacokinetics by altering either drug absorption or by affecting liver metabolism. Since patients suffering from chronic pancreatitis experience severe pain, opioids are often prescribed as pain treatment. Opioids have intrinsic effects on gastrointestinal motility and hence can modify the absorption of other drugs taken at the same time. Furthermore, the increased fluid absorption caused by opioids will decrease water available for drug dissolution and may hereby affect absorption of the drug. As stated above many factors can influence drug absorption and metabolism in patients with chronic pancreatitis. The factors may not have clinical relevance, but may explain inter-individual variations in responses to a given drug, in patients with chronic pancreatitis.

    In spite of continuous research efforts directed at early detection and treatment of pancreatic cancer, the outlook for patients affected by the disease remains dismal. With most cases still being diagnosed at advanced stages, no improvement in survival prognosis is achieved with current diagnostic imaging approaches. In the absence of a dominant precancerous condition, several risk factors have been identified including family history, chronic pancreatitis, smoking, diabetes mellitus, as well as certain genetic disorders such as hereditary pancreatitis, cystic fibrosis, familial atypical multiple Most pancreatic carcinomas, however, remain sporadic. Current progress in experimental molecular techniques has enabled detailed understanding of the molecular processes of pancreatic cancer development. According to the latest information, malignant pancreatic transformation involves multiple oncogenes and tumor-suppressor genes that are involved in a variety of signaling pathways. The most characteristic aberrations (somatic point mutations and allelic losses) affect oncogenes and tumor-suppressor genes within RAS, AKT and Wnt signaling, and have a key role in transcription and proliferation, as well as systems that regulate the cell cycle (SMAD/DPC, CDKN2A/p16) and apoptosis (TP53). Understanding of the underlying molecular mechanisms should promote development of new methodology for early diagnosis and facilitate improvement in current approaches for pancreatic cancer treatment.

    An obese lady of 51 year with Type 2 Diabetes Mellitus for 13 years was prescribed Liraglutide, a glucagon like peptide (GLP-1) analogue (Victoza) for glycaemic control and reduction of weight. She was on gliclazide and Insulin prior to initiation of Liraglutide. Eight weeks after initiation of GLP -1 analogue, she developed severe abdominal pain, nausea and vomiting. She was admitted to a private hospital and evaluated. Biochemical tests and CT scan revealed presence of pancreatitis and she was treated for acute pancreatitis. Liraglutide was withdrawn and symptoms subsided. Subsequent follow-up showed that pancreatic enzyme levels were normal. PMID:25327099

    Technical complications are relatively common after pancreatic transplantation, and most require radiological evaluation. Ultra sonography and computed tomography are helpful in the identification of peripancreatic and intra-abdominal fluid collections. Sterile fluid collections can be effectively treated by percutaneous catheter drainage, whereas most intra-abdominal infections require surgical intervention. Angiography is performed primarily for diagnosis of vascular thrombosis. Recent results suggest that magnetic resonance may be a useful non-invasive method for the detection of pancreatic transplant rejection. Further imaging studies are needed to better define the development of progressive fibrotic atrophy in long-term functioning pancreatic transplants.

    Pancreatic cancer is a highly aggressive malignancy with a poor prognosis and deeply affects the life of people. Therefore, the earlier diagnosis and better treatments are urgently needed. In recent years, the proteomic technologies are well established and growing rapidly and have been widely applied in clinical applications, especially in pancreatic cancer research. In this paper, we attempt to discuss the development of current proteomic technologies and the application of proteomics to the field of pancreatic cancer research. This will explore the potential perspective in revealing pathogenesis, making the diagnosis earlier and treatment. PMID:22084685

    Acute pancreatitis is a frequent inflammatory and necrotic process of pancreas and peripancreatic field. To detect the presence of infected or sterile necrotic components and hemorrhage of the pancreatic paranchyma is important for therapeutic approach. Chronic pancreatitis is characterized by irreversible exocrine dysfunction, progressive loss of pancreatic tissue and morphological changes of the pancreatic canal. Imaging modalities play a primary role in the management of both acute and chronic pancreatitis. CT and MR imaging confirm the diagnosis and detect the severity of disease. In chronic pancreatitis, MRCP after Secretin administration, Spiral CT and endoscopic US seems to replace diagnostic ERCP. However differentiation of pseudotumor of chronic pancreatitis from the pancreatic carcinoma is difficult with either imaging modalities.

    Magnetic resonance (MR) imaging plays an important role in the diagnosis and staging of acute and chronic pancreatitis and may represent the best imaging technique in the setting of pancreatitis due to its unmatched soft tissue contrast resolution as well as non-ionizing nature and higher safety profile of intravascular contrast media, making it particularly valuable in radiosensitive populations such as pregnant patients, and patients with recurrent pancreatitis requiring multiple follow-up examinations. Additional advantages include the ability to detect early forms of chronic pancreatitis and to better differentiate adenocarcinoma from focal chronic pancreatitis. This review addresses new trends in clinical pancreatic MR imaging emphasizing its role in imaging all types of acute and chronic pancreatitis, pancreatitis complications and other important differential diagnoses that mimic pancreatitis.

    International Nuclear Information System (INIS)

    Modern imaging techniques have revolutionized the diagnostic evaluation of pancreatitis, primarily demonstrating its complications. Computerized tomography (CT) is a more sensitive method than ultrasonography and pancreatic ductography. A chart review revealed 214 patients at our hospital with a discharge diagnosis of pancreatitis. Sixty patients had CT for evaluation of possible complications. Only five scans were normal. Of 37 cases of acute pancreatitis, 92% demonstrated localized or diffuse enlargement, and 65% showed loss of pancreatic outline. Other frequent findings included thickening of perirenal fascia (49%), ileus (43%), edema of mesentery (35%), and inflammatory exudate (32%). Abscess and pseudocyst were each detected in 8% of cases. In chronic pancreatitis 65% of patients showed localized or diffuse pancreatic enlargement. Atrophy of the gland (30%), calcification (30%), pseudocyst (26%), and dilated pancreatic ducts (17%) were also seen. CT is effective in evaluating pancreatitis and its complications. 14 references, 5 figures, 2 tables

    Whether acute recurrent pancreaUtis is a chronic disease is still debated and a consensus is not still reached as demonstrated by differences in the classification of acute recurrent pancreatitis.There is major evidence for considering alcoholic pancreatitis as a chronic disease ab initio while chronic pancreatitis lesions detectable in biliary acute recurrent pancreatitis (ARP) seem a casual association.Cystic fibrosis transmembrane con ductance regulator (CFTR) gene mutation,hereditary and obstructive pancreatitis seem an acute disease that progress to chronic pancreatitis,likely as a consequence of the activation and proliferation of pancreatic stellate cells that produce and activate collagen and therefore fibrosis.From the diagnostic point of view,in patients with acute recurrent pancreatitis Endoscopic ultrasound (EUS) seems the more reliable technique for an accurate evaluation and follow-up of some ductal and parenchymal abnormalities suspected for early chronic pancreatitis.

  12. Diagnosis of acute necrotizing pancreatitis and acute hemorrhagic pancreatitis in 5 severe acute pancreatitis by plain computed tomography

    The diagnosis of acute pancreatitis is still mainly based on the clinical signs and symptoms of patients. In a prospective study of 64 patients with acute pancreatitis, computed tomography (CT) findings were correlated with the clinical types of acute pancreatitis. We were able to correctly diagnose 3 acute necrotizing pancreatitis with autopsy and 2 acute hemorrhagic pancreatitis by plain CT about 48 hours after onset. At present, CT about 48 hours after onset seems to be the most accurate method for the early detection of necrotizing, hemorrhagic and edematous forms of acute pancreatitis. (author)

  14. CT of the superior mesenteric artery root in pancreatitis and pancreatic carcinoma

    International Nuclear Information System (INIS)

    Previous reports suggested that pancreatitis does not produce CT changes in the region of the root of the superior mesenteric artery (SMA) while pancreatic carcinoma does. The authors have reviewed 103 CT studies from patients with proved pancreatitis (n = 61) or pancreatic carcinoma (n = 42). Masked CT studies (obscuring all regions except the root of the SMA) were evaluated for infiltration of the fat around the SMA, adjacent lymph nodes, focal mass abutting the SMA, and mass circumferentially encasing the SMA. Streaky infiltration around the SMA was seen in patient with pancreatitis (58%) and pancreatic carcinoma (52%). Lymph nodes were seen in both pancreatitis (28%) and carcinoma (17%). Focal mass abutting the SMA was seen in pancreatitis (7%) and carcinoma (26%). Encasement of the SMA was seen only in carcinoma (17%). Both pancreatitis and pancreatic carcinoma can produce CT findings in the region of the root of the SMA. Encasement of the SMA was the only finding specific to patients with pancreatic carcinoma

    Pancreatic tumors are infrequent in children. We are reporting the imaging diagnostic findings observed in a 9 patient series managed during the 1989-2000 with different types of pancreatic neoplasms (insulinoma n=2, pancreatoblastoma n=1, solid papillary-cystic carcinoma n=4, and adenocarcinoma n=2). Imaging exams included: ultrasonography, computed tomography, angiography and magnetic resonance. Imaging studies were useful to demonstrate the tumoral mass in 8/9 cases (89%), with only one false negative case (insulinoma). In this patient (6 years old), US, CT and angiography were negative for pancreatic tumor; final diagnosis was achieved by venous insulin dosimetry and intraoperative US. Pancreatic localization was determined in 7/9 cases (77%), excluding an undetected insulinoma and a huge pancreatoblastoma (14 x 10 cm). However, the imaging diagnosis was useful for staging and planning an adequate surgical approach. (author)

    Dynamic computed tomography was performed on 19 patients with clinically diagnosed pancreatic and peripancreatic tumors. There were 10 patients with pancreatic cancer, three with inflammatory pancreatic masses, two with cystadenoma, one with insuloma, and three with peripancreatic tumors. Computed tomography was performed with a Varian-V-360-3 scanner; scanning was for 30 consecutive sec at 3 sec intervals after the bolus injection of 50 ml of contrast medium into the antecubital vein. Dynamic computed tomography (CT) may be more useful than conventional contrast CT because it facilitates: (1) correct evaluation of tumor vascularity allowing a differential diagnosis; (2) location of the boundary between tumor and a nontumor tissue; (3) detection of small tumors; and (4) visualization of pancreatic invasion by peripancreatic tumors. In addition, contrast enhancement and the degree of vascular proliferation can be quantitatively assessed by analyzing time-density curves.

    The diagnosis of pancreatic cancer is devastating for patients and their relatives as the incidence rate is approximately the same as mortality rate. Only a small percentage, which ranges from 0.4% to 4% of patients who have been given this diagnosis, will be alive at five years. At the time of diagnosis, 80% of pancreatic cancer patients have unresectable or metastatic disease.Moreover, the therapeutic alternatives offered by chemotherapy or radiotherapy are few, if not zero. For all these reasons, there is an imperative need of analyzing and understanding the primitive lesions that lead to invasive pancreatic adenocarcinoma. Molecular pathology of these lesions is the key of our understanding of the mechanisms underlying the development of this cancer and will probably help us in earlier diagnosis and better therapeutic results. This review focuses on medical research on pancreatic cancer models and the underlying genetic alterations.

    Full Text Available The management of acute pancreatitis differs according to its severity. Approximately 75% of patients with acute pancreatitis have mild disease with a mortality rate below 1%. Mortality increases up to 20% if the disease progresses to its severe necrotizing form and, in the most severe cases, mortality can increase to 30-40%. Severe acute pancreatitis is usually accompanied by systemic inflammatory response syndrome (SIRS which results in hypermetabolism with prominent protein catabolism. Acute malnutrition, commonly observed in patients with acute pancreatitis, is associated with immunological disturbances, septic complications and delayed healing of surgical wounds, and may lead to multiorgan dysfunction or failure syndrome (MODS or MOFS and increased morbidity and mortality [1].

    The diagnosis of acute pancreatitis is based on anamnestic, clinical and chemical data. Ultrasound and computed tomography permit direct visualisation of the pancreas and establish the diagnosis. In cases of haemorrhagic-necrotising pancreatitis they demonstrate the extent of morphological changes and permit exclusion of other causes of an acute abdomen. The imaging methods support indications for operation in cases of subtotal or total parenchymatous necrosis and in pancreatic abscesses. Conservative expectant approaches in patients with severe clinical course and slight morphological changes as well as in agreement of clinical and morphological findings are facilitated. Complete demonstration of parenchymatous and peripancreatic necroses furnishes useful additional information for total extirpation. Gallstone disease can be demonstrated or excluded preoperatively. Since introduction of ultrasound and computed tomography for the diagnosis of acute pancreatitis a marked diminution of early surgical intervention and delayed operation has been achieved.

  12. Autoimmune pancreatitis. An update

    International Nuclear Information System (INIS)

    Autoimmune pancreatitis (AIP) is a rare disease, the pathophysiological understanding of which has been greatly improved over the last years. The most common form, type 1 AIP belongs to the IgG4-related diseases and must be distinguished from type 2 AIP, which is a much rarer entity associated with chronic inflammatory bowel disease. Clinically, there is an overlap with pancreatic cancer. Imaging and further criteria, such as serological and histological parameters are utilized for a differentiation between both entities in order to select the appropriate therapy and to avoid the small but ultimately unnecessary number of pancreatectomies. The diagnostics of AIP are complex, whereby the consensus criteria of the International Association of Pancreatology have become accepted as the parameters for discrimination. These encompass five cardinal criteria and one therapeutic criterion. By applying these criteria AIP can be diagnosed with a sensitivity of 84.9 %, a specificity of 100 % and an accuracy of 93.8 %. The diagnosis of AIP is accomplished by applying several parameters of which two relate to imaging. As for the routine diagnostics of the pancreas these are ultrasound, computed tomography (CT) and magnetic resonance imaging (MRI). Important for the differential diagnosis is the exclusion of signs of local and remote tumor spread for which CT and MRI are established. The essential diagnostic parameter of histology necessitates sufficient sample material, which cannot usually be acquired by a fine needle biopsy. CT or MRI are the reference standard methods for identification of the optimal puncture site and imaging-assisted (TruCut) biopsy. In patients presenting with unspecific upper abdominal pain, painless jaundice combined with the suspicion of a pancreatic malignancy in imaging but a mismatch of secondary signs of malignancy, AIP should also be considered as a differential diagnosis. As the diagnosis of AIP only partially relies on imaging radiologists also

    Full Text Available Gallstones are the commonest cause of acute pancreatitis (AP, a potentially life-threatening condition, worldwide. The pathogenesis of acute pancreatitis has not been fully understood. Laboratory and radiological investigations are critical for diagnosis as well prognosis prediction. Scoring systems based on radiological findings and serologic inflammatory markers have been proposed as better predictors of disease severity. Early endoscopic retrograde cholangiopancreatography (ERCP is beneficial in a group of patients with gallstone pancreatitis. Laparoscopic cholecystectomy with preoperative endoscopic common bile duct clearance is recommended as a treatment of choice for acute biliary pancreatitis. The timing of cholecystectomy, following ERCP, for biliary pancreatitis can vary markedly depending on the severity of pancreatitis

    Pancreatic cancer is without any doubt the malignancy with the poorest prognosis and the lowest survival rate. This highly aggressive disease is rarely diagnosed at an early stage and difficult to treat due to its resistance to radiotherapy and chemotherapy. Therefore, there is an urgent need to clarify the causes responsible for pancreatic cancer and to identify preventive strategies to reduce its incidence in the population. Some circumstances, such as smoking habits, being overweight and d...

    Autoimmune pancreatitis (AIP) can be chronic or recurrent, but frequently completely reversible after steroid treatment. A cystic lesion in AIP is a rare finding, and it can mimic a pancreatic cystic neoplasm. Difficulties in an exact diagnosis interfere with treatment, and surgery cannot be avoided in some cases. We report the history of a 63-year-old male presenting with jaundice and pruritus. AIP was confirmed by imaging and elevated IgG4 blood levels, and the patient completely recovered ...

    Pancreatic cancer is a major problematic concern among all forms of gastrointestinal malignancies because of its poor prognosis. Although significant progress has been made in the surgical treatment in terms of increased resection rate and decreased treatment-related morbidity and mortality, the true survival rate still remains below 5% today. Surgical options for pancreatic cancer are based on the its unique anatomy and physiology, catastrophic tumor biology, experience of surgeon, and status of patients. Four main options exist for the surgical treatment of pancreatic cancer. These include standard "Whipple" pancreaticoduodenectomy (PD), pylorus preserving PD (PPPD), distal pancreatectomy (left-side pancreatectomy), and total pancreatectomy according to the location of tumor. Portal vein involvement by tumor is regarded as an anatomical extension of disease, and en bloc resection of portal vein with tumor is recommended if technically feasible, which is stated in 2002 AJCC tumor staging for pancreatic cancer. In comparison of the survival rates between standard and extended resection of pancreatic head cancer, no significant survival benefit was demonstrated from the prospective reports. PPPD may be superior to standard PD in respect to nutrition and quality of life without any deleterious effect upon long term survival or tumor recurrence. New surgical treatment modalities including modified extended pancreatectomy, neoadjuvant chemotherapy, and radical antegrade modular distal pancreatectomy have been tried to improve the patients' survival. However, early diagnosis and treatment remain as key factors for the cure of pancreatic cancer irrespective of various surgical trials. PMID:18349571

    Full Text Available Abstract The incidence and mortality of pancreatic adenocarcinoma are nearly coincident having a five-year survival of less than 5%. Enormous advances have been made in our knowledge of the molecular alterations commonly present in ductal cancer and other pancreatic malignancies. One significant outcome of these studies is the recognition that common ductal cancers have a distinct molecular fingerprint compared to other nonductal or endocrine tumors. Ductal carcinomas typically show alteration of K-ras, p53, p16INK4, DPC4 and FHIT, while other pancreatic tumor types show different aberrations. Among those tumors arising from the exocrine pancreas, only ampullary cancers have a molecular fingerprint that may involve some of the same genes most frequently altered in common ductal cancers. Significant molecular heterogeneity also exists among pancreatic endocrine tumors. Nonfunctioning pancreatic endocrine tumors have frequent mutations in MEN-1 and may be further subdivided into two clinically relevant subgroups based on the amount of chromosomal alterations. The present review will provide a brief overview of the genetic alterations that have been identified in the various subgroups of pancreatic tumors. These results have important implications for the development of genetic screening tests, early diagnosis, and prognostic genetic markers.

  3. Radiologic evaluation of pancreatic pseudocyst

    International Nuclear Information System (INIS)

    Pancreatic pseudocyst is a collection of necrotic tissue, old blood and secretions that escaped from the pancreas damaged by pancreatitis, trauma and chronic alcoholism. There is no epithelial cell lining the cystic wall. With the advent of ultrasound and CT more accurate diagnosis can be made. Our study was carried out to analyse the radiological and clinical findings of 32 cases of pancreatic pseudocysts confirmed at Wonju College of Medicine Yonsei University from Jan. 1979 to Aug. 1986. The results are as follows: 1. Male to female ratio was 4.3:1 Incidence was the most common in 4th decades. 2. The most frequent symptom was epigastric pain (100%). 3. In a total of 32 cases, 15 cases had a underlying cause of pancreatitis, 9 cases abdominal trauma. 4. In laboratory findings, serum amylase level was elevated in 23 cases, leucocytosis in 10 cases. 5. On chest films, the lungs were mostly normal. Soft tissue mass density in 12 cases was the most common finding on abdomen films. 6. UGI series were helpful in directing attention by pancreatic pseudocysts' location and size. 7. Ultrasonogram using primary procedure for the detection of pseudocyst (23 cases) disclosed anechoic lesion in 8 cases, mixed echo lesion in 15 cases. Mixed echo patterns, in terms of internal echo patters, were echogenic spots (8 cases), septation and echogenic spots (3 cases), fluid-fluid level (3 cases), etc. 8. CT scanning is the best imaging procedure, providing detailed morphologic information about the pancreatic pseudocyst and surrounding tissue.

    International Nuclear Information System (INIS)

    Aim: To describe the typical CEUS pattern of pancreatic lesions and to evaluate the diagnostic accuracy of Contrast-enhanced ultrasound (CEUS) in their characterization. Materials and methods: All US and CEUS examinations of focal pancreatic masses performed in six centers during a period of five years were reviewed. Inclusion criteria were: focal pancreatic mass pathologically proved, visible at ultrasound (US) and studied with CEUS. All lesions were then evaluated for size, aspect and enhancement pattern. Sensitivity, specificity, positive and negative predictive values with 95% CIs were calculated to define diagnostic accuracy of CEUS in respect to pathology. Diagnostic confidence of US and CEUS, discerning between benign and malignant lesions, were represented by using ROC (receiver operating characteristics) curves. Agreement was evaluated by means of k statistics. Results: 1439 pancreatic lesions were included. At CEUS the lesions were divided into solid (89%) and cystic (12%) masses and classified into six and eight categories, respectively. Among the solid lesions, adenocarcinomas were characterized with an accuracy of 87.8%. Among the cystic lesions, cystic tumors were diagnosed with an accuracy of 97.1%. ROC curve area increased from 0.637 for US to 0.877 for CEUS (p < 0.0001). Inter-observer agreement was slightly higher for solid (k = 0.78) than cystic (k = 0.62) lesions. In none of the centers side effects were reported. Conclusion: CEUS is accurate in the characterization of pancreatic lesions. CEUS should be considered as a complementary imaging method for pancreatic lesions characterization.

    Full Text Available CONTEXT: Salmonella has been identified as a causative agent of acute pancreatitis. OBJECTIVE: We prospectively evaluated the frequency of acute pancreatitis, pancreatic enzyme elevation and morphological pancreatic abnormalities in patients with Salmonella infection. SUBJECTS: Thirty consecutive patients with salmonellosis (Salmonella enterica serovar Enteritidis: n=25; Salmonella enterica serovar Typhimurium: n=5 and 30 sex- and age-matched healthy subjects were studied. MAIN OUTCOME MEASURES: All subjects underwent serum amylase and lipase determination and ultrasonography. RESULTS: None of the subjects developed acute pancreatitis. Two patients (6.7% and two controls showed serum amylase activity above the upper reference limit whereas, in five patients (16.7% and one control subject (3.3%, the serum lipase activity appeared above the upper reference limit. Salmonella infection significantly increased serum activity of lipase (P less than 0.001 while it did not significantly affect serum amylase levels (P=0.204. Serum lipase activity was significantly higher in patients infected by Salmonella enterica serovar Typhimurium than in those infected by Salmonella enterica serovar Enteritidis (P=0.012. Ultrasonography did not show pancreatic abnormalities in any of the subjects. CONCLUSIONS: Our data demonstrated an elevation of serum lipase activity in gastroenteritis due to Salmonella infection, but this elevation does not seem to have clinical significance. The elevation of serum lipase seems to be particularly related to infection from Salmonella enterica serovar Typhimurium.

  7. Radiotherapy in pancreatic cancer

    International Nuclear Information System (INIS)

    Purpose and approach: to summarize the current knowledge on the role of radiotherapy in the treatment of pancreatic ductal adenocarcinoma (PDAC). The results of meta-analyses, phase III-studies, and phase II-studies using chemoradiation (CRT) and chemotherapy for resectable and non-resectable PDAC are reviewed. Results and conclusion: the role of CRT is undefined in the adjuvant setting but there may be a role as additive treatment after R1 resection. Locally advanced borderline resectable tumors may shrink down and be subject to potentially curative resections. In locally advanced clearly unresectable cancers the effect of CRT as well as chemotherapy is poorly defined and the sequence of chemotherapy and CRT should be re-evaluated. Patients with PDAC should always be treated within studies to identify optimal treatment results. (orig.)

    2013-05-01

    Pancreatic stellate cells (PSCs) and other pancreatic components that play a critical role in exocrine pancreatic diseases are generally identified separately by conventional studies, which provide indirect links between these components. Here, nonlinear optical microscopy was evaluated for simultaneous characterization of these components within a three-dimensional (3-D) tissue environment, primarily based on multichannel detection of intrinsic optical emissions and cell morphology. Fresh rat pancreatic tissues harvested at 1 day, 7 days, and 28 days after induction of chronic pancreatitis were imaged, respectively. PSCs, inflammatory cells, blood vessels, and collagen fibers were identified simultaneously. The PSCs at day 1 of chronic pancreatitis showed significant enlargement compared with those in normal pancreas (ppancreatic components coincidently within 3-D pancreatic tissues. It is a prospect for intravital observation of dynamic events under natural physiological conditions, and might help uncover the key mechanisms of exocrine pancreatic diseases, leading to more effective treatments.

    Pancreatitis is the most common disorder of the exocrine pancreas in both dogs and cats. Ante-mortem diagnosis of canine and feline pancreatitis can be challenging. The clinical picture of dogs and cats with pancreatitis varies greatly (from very mild to severe or even fatal) and is characterised by non-specific findings. Complete blood count, serum biochemistry profile and urinalysis should always be performed in dogs and cats suspected of having pancreatitis, although findings are not-specific for pancreatitis. Serum amylase and lipase activities and trypsin-like immunoreactivity (TLI) concentrations have no or only limited clinical value for the diagnosis of pancreatitis in either dogs or cats. Conversely, serum pancreatic lipase immunoreactivity (PLI) concentration is currently considered to be the clinicopathological test of choice for the diagnosis of canine and feline pancreatitis. Abdominal radiography is a useful diagnostic tool for the exclusion of other diseases that may cause similar clinical signs to those of pancreatitis. Abdominal ultrasonography can be very useful for the diagnosis of pancreatitis, but this depends largely on the clinician's experience. Histopathological examination of the pancreas is considered the gold standard for the diagnosis and classification of pancreatitis, but it is not without limitations. In clinical practice, a combination of careful evaluation of the animal's history, serum PLI concentration and abdominal ultrasonography, together with pancreatic cytology or histopathology when indicated or possible, is considered to be the most practical and reliable means for an accurate diagnosis or exclusion of pancreatitis compared with other diagnostic modalities.

    Inflammation and autophagy are cellular defense mechanisms. When these processes are deregulated (deficient or overactivated) they produce pathologic effects, such as oxidative stress, metabolic impairments, and cell death. Unresolved inflammation and disrupted regulation of autophagy are common features of pancreatitis and pancreatic cancer. Furthermore, obesity, a risk factor for pancreatitis and pancreatic cancer, promotes inflammation and inhibits or deregulates autophagy, creating an env...

    The extracellular matrix molecule periostin (POSTN, encoded by POSTN), which is secreted by activated pancreatic stellate cells, has important functions in chronic pancreatitis and pancreatic cancer. However, the role of POSTN in acute pancreatitis and subsequent regeneration processes has not been addressed so far. We analyzed the function of POSTN in pancreatic exocrine regeneration after the induction of a severe acute pancreatitis. Postn-deficient mice and wild-type control animals received repetitive cerulein injections, and a detailed histologic analysis of pancreatic tissues was performed. Although there was no difference in pancreatitis severity in the acute inflammatory phase, the recovery of the exocrine pancreas was massively impaired in Postn-deficient mice. Loss of Postn expression was accompanied by strong pancreatic atrophy and acinar-to-adipocyte differentiation, which was also reflected in gene expression patterns. Our data suggest that POSTN is a crucial factor for proper exocrine lineage-specific regeneration after severe acute pancreatitis. PMID:26632158

  14. Angiographic diagnosis and differentiation of pancreatic tumours

    International Nuclear Information System (INIS)

    In an 8-year period (1971-1978) 92 patients were examined because of suspected pancreatic tumour and the following symptoms were found: in 13 cases (14.1%) inoperable pancreatic carcinoma, in 2 cases insuloma, in 5 patients pancreatic cyst, in 5 cases pancreatitis, in one patient pancreatic abscess and in 12 cases alterations in the environing organs. The observed angiographic symptoms are described in detail. Except the richly vascularized tumour grown together with the stomach all pancreatic carcinomas were poor in vessels and they caused tumourous invasions in the greater arteries. The obliteration of the lienal vein, as well as the development of mesenteric venous collateral circulation signify an inoperable stage. The signs of the differential diagnosis of the pancreatitis and the carcinoma are dealt with in detail. In case of secondary pancreatic tumours - not even detectable by post-mortem examination - the angiographic signs are to be taken into consideration. (author)

    A 42 year-old woman with severe acute pancreatitis had drainage of the pancreatic bed, cholecystostomy and jejunostomy on admission, but symptoms were not improved. Fourteen days after admission, clinical sepsis and septisemia were recognized. Dynamic CT scanning of the pancreas showed near total pancreatic necrosis. Symptoms were improved after necrosectomy of the pancreas and debridement of the peripancreatic necrotic tissue were performed. Our experience suggests the usefulness of dynamic CT scanning for detection of pancreatic necrosis in severe acute pancreatitis.

    Chronic pancreatitis is defined as a continuous inflammatory pancreatic disease, one characterized by irreversible morphological changes, often associates with pain and sometimes with the loss of endocrine and exocrine function. As a histological confirmation of chronic pancreatitis is often unavailable, the diagnosis is traditionally based on imaging methods such as computerized tomography (CT) or endoscopic retrograde cholangiopancreatography (ERCP), and recently magnetic resonance cholangiopancreatography (MRCP) as a noninvasive alternative to ERCP. Developments in the classification system of CP include the Marseille classification of 1963 which offered histopathologic criteria for CP, the Cambridge classification of 1984 which introduced imaging features of computed tomography (CT), transabdominal ultrasound (TUS) and endoscopic retrograde cholangiopancreatography (ERCP) for classification of CP as well as Rosemont classification system of 2007 which presented the endoscopic ultrasonography diagnosis of CP. Endoscopic ultra-sonography (EUS) was first introduced as a diagnostic method for evaluation of pancreatic disease in 1986. It has experienced significant improvements since then and allowed for an alternative approach in diagnosing patients with pancreatic diseases. In patients with suspected pancreatic masses EUS-guided fine needle aspiration (EUS-FNA) is the best method for obtaining tissue diagnosis and differentiating CP from pancreatic carcinoma. The recent studies indicate that EUS is the method of choice when compared with other imaging methods such as ERCP because it frequently provides more accurate diagnostics. The aim of this review is to discuss the findings in endoscopic diagnostics up to the present moment and to indicate advantages, limitations and possible complications along with the current recommendations in CP diagnostics.

    2016-02-01

    Necrotizing pancreatitis is a serious medical problem that often requires intervention to debride necrotic pancreatic and peripancreatic tissue. Recently, minimally invasive approaches have been applied to pancreatic necrosectomy. The purpose of this report is to review the history of transgastric pancreatic debridement, identify appropriate patient selection criteria, and highlight technical "pearls." We present this subject matter in the context of our own clinical experience, with a primary focus on a "How I Do It" type of technical description. PMID:26691148

    Eosinophilic pancreatitis (EP) is a rare clinical entity, and few cases have been reported. It usually presents on imaging as a pancreatic mass leading to common bile duct obstruction and jaundice. Since it can mimic a malignancy, eosinophilic pancreatitis is often diagnosed after “false positive” pancreatic resections. To our knowledge, we report the only known case of EP in which the diagnosis was made by fine needle aspiration and core biopsy of the pancreas during EUS, sparing the patient...

    2016-02-28

    Blunt pancreatic trauma is an uncommon injury but has high morbidity and mortality. In modern era of trauma care, pancreatic trauma remains a persistent challenge to radiologists and surgeons alike. Early detection of pancreatic trauma is essential to prevent subsequent complications. However early pancreatic injury is often subtle on computed tomography (CT) and can be missed unless specifically looked for. Signs of pancreatic injury on CT include laceration, transection, bulky pancreas, heterogeneous enhancement, peripancreatic fluid and signs of pancreatitis. Pan-creatic ductal injury is a vital decision-making parameter as ductal injury is an indication for laparotomy. While lacerations involving more than half of pancreatic parenchyma are suggestive of ductal injury on CT, ductal injuries can be directly assessed on magnetic resonance imaging (MRI) or encoscopic retrograde cholangio-pancreatography. Pancreatic trauma also shows temporal evolution with increase in extent of injury with time. Hence early CT scans may underestimate the extent of injures and sequential imaging with CT or MRI is important in pancreatic trauma. Sequential imaging is also needed for successful non-operative management of pancreatic injury. Accurate early detection on initial CT and adopting a multimodality and sequential imaging strategy can improve outcome in pancreatic trauma. PMID:26981225

    The main pancreatic duct has been visualized with both ultrasound and computed tomography. A normal pancreatic duct has been reported using CT, and controversy persists over whether a normal duct can be routinely imaged with ultrasound. The dilated pancreatic duct has always been associated with disease - usually pancreatitis or a proximal obstructing pancreatic carcinoma. In the patient with no clinical history or laboratory data suggesting pancreatitis, a dilated pancreatic duct implies a proximal tumor.

  7. Pancreatic Lesion: Malignancy or Abscess?

    Science.gov (United States)

    Shulik, Oleg; Cavanagh, Yana; Grossman, Matthew

    2016-01-01

    BACKGROUND Pancreatic abscesses are rare. They may be seen in patients with pancreatic inflammation or pancreatitis. Patients with pancreatic abscesses may have abdominal pain, fever, chills, and nausea/vomiting or an inability to eat. Presentation with alternate symptomatology is extremely unusual. CASE REPORT A 67-year-old Asian male presented with painless, afebrile obstructive jaundice and a CA 19-9 of 1732 IU. He was found to have a 3.1×2.4 cm low-density lesion in the head of the pancreas and the right lobe of the liver, suggesting malignancy. Surgical management was considered, however additional diagnostic workup, including an endoscopic retrograde cholangiopancreatography (ERCP), was performed to complete staging of the presumed mass. A smooth, 3-cm-long, tapering stricture was found it the common bile duct. It was stented from the common hepatic duct to the duodenum. Subsequent endoscopic ultrasound (EUS) evaluation of the pancreatic head lesion revealed a drainable fluid collection that was aspirated and found to contain pyogenic material on pathology. The patient's symptoms resolved, and he was subsequently managed conservatively. A repeat ERCP confirmed complete resolution of the previously visualized cystic lesion. Interestingly, laboratory values showed concomitant normalization of CA 19-9 to 40 IU. CONCLUSIONS EUS-guided biopsy is not widely regarded as a required step before surgery, in the management of patients with pancreatic masses. It is generally reserved for determination of resectability or staging, and only utilized when clinically indicated. However, this practice may be associated with an inherently significant risk of misdiagnosis and subsequent unnecessary surgery, as illustrated by this case. Malignancy was initially suspected in our patient and surgical resection was recommended. Endoscopic measures were only pursued to complete staging. We propose that EUS-guided biopsy may be a crucial diagnostic step in the management algorithm

    2015-09-01

    Full Text Available Pancreatic pseudocyst is a complication of acute or chronic pancreatitis. The invasive treatment (surgical or endoscopic is recommended if the pseudocyst persisted for more than 6 weeks after the diagnosis and if the size is larger than 6 cm and is symptomatic. The laparoscopic techniques have been developed to provide the patient with the benefits of a minimal access alternative. The aim of this article is to analyze the postoperative results of the pancreatic pseudocyst laparoscopic surgery. We have accomplished a restrospective study using clinical and para-clinical test results and postoperative results from the patients who have been treated with laparoscopic drainage. We reported a case of a large symptomatic pseudocyst after an attack of gallstone pancreatitis. Laparoscopic cholecystectomy and extern drainage have been performed at the same time with good postoperative results. Starting with year 2000 until year 2015, 85 patients, diagnosed with pancreatic pseudocyst, have been treated in the First Surgical Clinic, University Hospital Saint Spiridon Iasi. From which only 8 have been treated with laparoscopic drainage, encountering no mortality and morbidity. Postoperative hospital stay was 9,41 days. The postoperative drainage duration was between 5 and 21 days with a mean of 7 days. Late postoperative results were good in 6 patients and mediocre in the 2 patients. Conclusion: The laparoscopic technique has all the benefits of the minimal invasive approach. Better postoperative results were seen in cysto-digestive anastomosis using a Endo GIA stapler.

    Pancreatic pseudocyst occurs as a complication of pancreatitis or trauma, which results in the escape of pancreatitis enzymes from the parenchyma or ductal system of pancreas. At that time, serum amylase may have retuned to normal level, and the patient may be subjectively asymptomatic. In this phase, the radiologic findings are relatively greater significance than laboratory data. In the conventional radiologic study, pancreatic pseudocyst have been frequently confused with other retroperitoneal mass, but recently with clinical application of ultrasound and CT scan, more accurate diagnosis can be obtained. The brief results are as follows: 1. Male to female ratio was 3 : 2 in 15 patients. Incidence was more common in young adult age. Most frequent symptom was epigastric pain, and which was noted in 11 cases of patients. 7 cases of patients had past history of abdominal trauma and past history of pancreatitis was only in 1 case. Most common laboratory findings was leukocytosis in 8 cases of patients and elevated serum amylase was also noted in 7 cases. 2. In each 5 cases of patients, plain chest roentgenologic evidence of left side pleural effusion and hemidiaphragm elevation were observed. 3. On flat abdomen film, soft mass shadow was visualized in 8 cases of patients. On UGI series, evidence of retrogastric space widening was observed in 11 cases of patients. 4. The location of pseudocyst is mainly in body and tail of pancrease in 11 cases of patients. 5. More accureable diagnosis can be obtained through application of ultrasound and CT scan.

    Pancreatic cancer is the fifth most aggressive malignancy and urgently requires new biomarkers to facilitate early detection. For providing impetus to the biomarker discovery, we have developed Pancreatic Cancer Methylation Database (PCMDB, http://crdd.osdd.net/raghava/pcmdb/), a comprehensive resource dedicated to methylation of genes in pancreatic cancer. Data was collected and compiled manually from published literature. PCMdb has 65907 entries for methylation status of 4342 unique genes. In PCMdb, data was compiled for both cancer cell lines (53565 entries for 88 cell lines) and cancer tissues (12342 entries for 3078 tissue samples). Among these entries, 47.22% entries reported a high level of methylation for the corresponding genes while 10.87% entries reported low level of methylation. PCMdb covers five major subtypes of pancreatic cancer; however, most of the entries were compiled for adenocarcinomas (88.38%) and mucinous neoplasms (5.76%). A user-friendly interface has been developed for data browsing, searching and analysis. We anticipate that PCMdb will be helpful for pancreatic cancer biomarker discovery.

  13. Differentiation of autoimmune pancreatitis from suspected pancreatic cancer by fluorine-18 fluorodeoxyglucose positron emission tomography

    International Nuclear Information System (INIS)

    Fluorine-18 fluorodeoxyglucose positron emission tomography (FDG-PET) has been widely used for the diagnosis of pancreatic cancer. Because autoimmune pancreatitis is easily misdiagnosed as pancreatic cancer and can be tested for by FDG-PET analysis based on the presence of suspected pancreatic cancer, we attempted to clarify the differences in FDG-PET findings between the two conditions. We compared FDG-PET findings between 15 patients with autoimmune pancreatitis and 26 patients with pancreatic cancer. The findings were evaluated visually or semiquantitatively using the maximum standardized uptake value and the accumulation pattern of FDG. FDG uptake was found in all 15 patients with autoimmune pancreatitis, whereas it was found in 19 of 26 patients (73.1%) with pancreatic cancer. An accumulation pattern characterized by nodular shapes was significantly more frequent in pancreatic cancer, whereas a longitudinal shape indicated autoimmune pancreatitis. Heterogeneous accumulation was found in almost all cases of autoimmune pancreatitis, whereas homogeneous accumulation was found in pancreatic cancer. Significantly more cases of pancreatic cancer showed solitary localization, whereas multiple localization in the pancreas favored the presence of autoimmune pancreatitis. FDG uptake by the hilar lymph node was significantly more frequent in autoimmune pancreatitis than in pancreatic cancer, and uptake by the lachrymal gland, salivary gland, biliary duct, retroperitoneal space, and prostate were seen only in autoimmune pancreatitis. FDG-PET is a useful tool for differentiating autoimmune pancreatitis from suspected pancreatic cancer, if the accumulation pattern and extrapancreatic involvement are considered. IgG4 measurement and other current image tests can further confirm the diagnosis. (author)

    International Nuclear Information System (INIS)

    Abdominal tuberculosis (TB) is one of the most common forms of extra-pulmonary tuberculosis and is responsible for considerable morbidity and mortality globally. Tuberculosis can involve any part of the gastrointestinal tract from mouth to anus, the peritoneum, liver, spleen and the pancreatobiliary system. The occurrence of abdominal TB is independent of pulmonary disease in most patients, with a reported incidence of co-existing pulmonary disease varying from 6 to 38% worldwide. We report a case of pancreatic tuberculosis also involving the vertebrae, which was initially treated as a case of pancreatic cancer. (author)

    Full Text Available Cancer pharmacogenetics is a popular and evolving field in medicine with applications in various types of tumours helping clinicians to apply a more personalized medicine by providing information of prognostic, predictive and therapeutic value. Such evidence of pharmacogenetic applications is been already available in colon cancer (e.g. KRAS status, mismatch repair genes status, UGT1A1 polymorphisms, lung cancer (EGFR mutations, ERCC1 mutations, breast cancer (HER2/neu overexpression and many others. In all these tumors, the genetic information is rendering the management of the involved patients safer and more effective. Interesting abstracts and announcements from the perspective of pharmacogenomics in pancreatic cancer included Abstract #4611 which suggested the use of a novel genomic study able to detect specific single nucleotide polymorphisms (SNPs with prognostic value, Abstract #4615 which showed that the known proteins alpha1-antitrypsin and alpha1-antichymotrypsin may be predictive of response to gemcitabine and survival, and Abstract #11097 which suggested that human R protein (HuR expression may be a useful predictive biomarker of gemcitabine treatment. The authors also present here a few other abstracts of pharmacogenomic interest which had negative findings, but believed to be of clinical importance.

    Percutaneous interventional therapy plays an important role in treating complications of acute and chronic pancreatitis. With the development of cross-sectional imaging and advanced interventional techniques, percutaneous drainage has become the preferred treatment for pancreatic fluid collections such as acute collections, pseudocysts and abscesses. Abscess and pancreatic hemorrhage are the most life threatening complications of pancreatitis. Massive hemorrhage is rare but frequently lethal. As a rule, bleeding complications of pancreatitis require prompt diagnosis and an aggressive surgical approach. In unstable patients with a severely bleeding pseudoaneurysm, hemostasis can be obtained by occlusion with mechanical devices.

    2016-01-01

    In light of the emerging diabetes epidemic, new experimental approaches in islet research are needed to elucidate the mechanisms behind pancreatic islet dysfunction and to facilitate the development of more effective therapies. Optogenetics has created numerous new experimental tools enabling us to gain insights into processes little was known about before. The spatial and temporal precision that it can achieve is also attractive for studying the cells of the pancreatic islet and we set out to explore the possibilities of this technology for our purposes. We here describe how to use the islets of an "optogenetic beta-cell" mouse line in islet batch incubations and Ca(2+) imaging experiments. This protocol enables light-induced insulin release and provides an all-optical solution to control and measure intracellular Ca(2+) levels in pancreatic beta-cells. The technique is easy to set up and provides a useful tool for controlling the activity of distinct islet cell populations. PMID:26965119

    2004-07-01

    Full Text Available Pancreatic cancer is the 10th most common malignancy and the 4th largest cancer killer in adults. Surgery offers the only chance of curing these patients. Complete surgical resection is associated with a 5-year survival rate of between 20 and 30%. The challenge is how to best select those patients for curative surgery. Early studies demonstrated excellent sensitivity of EUS in detecting pancreatic tumors in comparison to CT. Similarly, EUS showed an 85-94% accuracy rate for T staging and 70-80% accuracy rate for N staging. Later studies report on substantially less TN staging accuracy for EUS. Possible explanations and the problem of vascular involvement assessment by EUS will be provided. Considering the role of EUS in M staging and a comparison between EUS, MRI, and positron emission tomography, scanning will be presented. A diagnostic algorithm for the evaluation of patients with a suspected pancreatic mass will be offered, stressing the pivotal role of EUS.

    Ascariasis is a common helminthic disease worldwide, although Lithuania and other European countries are not considered endemic areas. The presence of the Ascaris worm in the biliary tree causes choledocholithiasis-like symptoms. We report a case of pancreatic duct ascariasis causing such symptoms. A 73-year-old Lithuanian woman underwent endoscopic retrograde cholangiopancreatography (ERCP) suspecting choledocholithiasis. Contrast injection into the common bile duct demonstrated a slightly dilated biliary tree without any filling defects, and the tail of an Ascaris worm protruding from the opening of the papilla Vater. The worm was captured by a snare but escaped deep into the duct. After a small wirsungotomy the worm was retrieved from the pancreatic duct. The patient received a 150 mg dose of levamisole orally repeated 7 days later and was discharged after complete resolution of symptoms. This first reported sporadic case of pancreatic duct ascariasis in Lithuania was successfully treated with ERCP and Levamisole. PMID:26374772

    Full Text Available Context Azathioprine induced pancreatitis usually runs a benign self limited course with rapid disappearance of signs and symptoms upon with drawl of the drug. Azathioprine is used in treating relapses in patients with autoimmune pancreatitis and maintenance of remission in autoimmune hepatitis. Acute pancreatitis complicated by symptomatic pseudocysts requiring drainage is not usually associated with drug induced pancreatitis. The risk of azathioprine use in patients with underlying disease of pancreas including autoimmune pancreatitis is unclear. Case report We report here a case of an African American patient with co-existing autoimmune pancreatitis and autoimmune hepatitis who developed azathioprine induced acute pancreatitis complicated by a large symptomatic pseudocyst compressing the duodenum requiring a cystoduodenostomy. Conclusions Future studies to investigate the risk of azathioprine induced pancreatitis in the presence of underlying disease of the pancreas including autoimmune pancreatitis are required to further understand the safety of azathioprine in this sub group of patients.

    Purpose: To clarify if the portal venous phase is helpful for the differential diagnosis of groove pancreatic carcinomas and groove pancreatitis. Materials and methods: MDCT and MRI of groove pancreatic carcinomas (n = 7) and groove pancreatitis (n = 15) were retrospectively reviewed by two radiologists independently. The signal intensity on T2-weighted images was subjectively assessed. The presence or absence of common bile duct (CBD) and main pancreatic duct (MPD) strictures, calcifications, and cystic lesions was evaluated. Additionally, the appearance of groove pancreatic carcinoma and that of groove pancreatitis in the portal venous phase on dynamic MDCT and MRI were compared. Results: There were no significant differences in the signal intensity on T2-weighted images and in the presence or absence of CBD and MPD strictures, calcifications, and cystic lesions between groove pancreatic carcinomas and groove pancreatitis. However, patchy focal enhancement in the portal venous phase was more commonly observed in groove pancreatitis than groove pancreatic carcinoma (Reviewers 1 and 2: 14/15 [93.3%] vs. 1/7 [14.3%], P < 0.0001). In addition, peripheral enhancement was only seen in groove pancreatic carcinomas (Reviewer 1: 4/7 [57.1%] vs. 0/15 [0%], P < 0.005, and Reviewer 2: 3/7 [42.9%] vs. 0/15 [0%], P < 0.05). Conclusion: The portal venous phase may be helpful for the differential diagnosis of groove pancreatic carcinomas and groove pancreatitis.

    Alcohol abuse is commonly associated with the development of both acute and chronic pancreatitis. Despite this close association, the fact that only a small percentage of human beings who abuse alcohol develop pancreatitis indicates that alcohol abuse alone is not sufficient to initiate clinical pancreatitis. This contention is further supported by the fact that administration of ethanol to experimental animals does not cause pancreatitis. Because of these findings, it is widely believed that ethanol sensitizes the pancreas to injury and additional factors trigger the development of overt pancreatitis. How ethanol sensitizes the pancreas to pancreatitis is not entirely known. Numerous studies have demonstrated that ethanol and its metabolites have a number of deleterious effects on acinar cells. Important acinar cells properties that are affected by ethanol include: calcium signaling, secretion of zymogens, autophagy, cellular regeneration, the unfolded protein response, and mitochondrial membrane integrity. In addition to the actions of ethanol on acinar cells, it is apparent that ethanol also affects pancreatic stellatecells. Pancreatic stellate cells have a critical role in normal tissue repair and the pathologic fibrotic response. Given that ethanol and its metabolites affect so many pancreatic functions, and that all of these effects occur simultaneously, it is likely that none of these effects is "THE" effect. Instead, it is most likely that the cumulative effect of ethanol on the pancreas predisposes the organ to pancreatitis. The focus of this article is to highlight some of the important mechanisms by which ethanol alters pancreatic functions and may predispose the pancreas to disease.

    @@INTRODUCTION It is axiomatic that the most effective and soundly based plan of treatment of any disorder is one aimed at the mechanism or mechanisms responsible for its development[1]. This basic notion, coupled with recent reports[2- 11] in which, surprisingly there is a total lack of reference to the probable involvement of autonomic-arc-reflexes in the physiopathogenesis of biliary acute pancreatitis have prompted this presentation. Undoubtedly, this disease entity has numerous causes, an obscure physiopathology, few effective remedies, and, often, an unpredictable outcome. At the turn of the century, Opie[12,13] brought to light the association between gallstone migration and acute pancreatitis.

    Full Text Available Pancreatic pseudocysts may appear as sequellae of acute or chronic pancreatitis or pancreatic trauma. Endoscopic drainage of pancreatic pseudocysts was introduced in the nineteen eighties. Three different types of drainage can be performed: transpapillary, transmural, and rendezvous techniques. Classic transgastric or transduodenal drainage of pseudocysts can be performed only when a bulging lesion is seen on endoscopy. Endosonography (EUS provides essential information prior to endoscopic drainage of pancreatic pseudocysts, leading to a change in therapy in one third of patients. With diagnostic EUS, interposed vessels, too large distance between pseudocyst and digestive lumen, and suspicion of neoplasic lesions can be identified, leading to a change in management. To increase the success rate of endoscopic drainage of pancreatic pseudocysts, interventional EUS seems to be very helpful. Interventional EUS offers the possibility to drain non-bulging pseudocysts and abscesses. Various methods to drain pancreatic pseudocysts by using EUS guidance have been reported in the literature. The first generation of interventional echo endoscopes provided only a 2 mm working channel and required reintroduction of a therapeutic duodenoscope over the guide wire to place the catheter. Today, several echo-endoscopes with working channels of at least 2.8 mm allow one step cyst drainage procedures with placement of 8.5 and 10 French stents or nose-cystic catheters. Endoscopic ultrasound guided pseudocyst drainage can have complications such as bleeding, perforation, infection, and stent migration. Haemorrhage, which is the main complication of endoscopic drainage of pancreatic pseudocysts, occurs in 6-15% of cases. The use of colour Doppler ultrasonography and balloon dilation of the drainage site may minimize the risk of vascular perforation during puncture. Bleeding at the puncture site is usually mild and rarely requires surgical intervention. Perforation of

    International Nuclear Information System (INIS)

    Objective: To study the MR imaging features of blunt pancreatic injury. Materials and methods: Nine patients with pancreatic injury related to blunt abdominal trauma confirmed by surgery performed MR imaging. Two abdominal radiologists conducted a review of the MR images to assess pancreatic parenchymal and pancreatic duct injury, and associated complications. Result: Diagnostic quality MR images were obtained in each of the nine patients. In the nine patients, pancreatic fracture, laceration and contusion were depicted on MR imaging in five, one and three patients, respectively. There were six patients with pancreatic duct disruption, eight patients with peripancreatic fluid collections, and four patients with peripancreatic pseudocyst or hematoma, respectively. All of the MR imaging findings was corresponded to surgical findings. Conclusion: MR imaging is an effective method to detect blunt pancreatic injury and may provide information to guide management decisions.

    2003-05-01

    Full Text Available CONTEXT: Few data exist about the incidence of drug-induced pancreatitis in the general population. Drugs are related to the etiology of pancreatitis in about 1.4-2% of cases. Statins are generally well tolerated. Acute pancreatitis has been reported in a few cases treated with atorvastatin, fluvastatin, lovastatin and simvastatin. CASE REPORT: We report the case of a 56-year-old patient who, after 6 months of treatment with pravastatin 20 mg once daily for hypercholesterolemia, presented with acute pancreatitis. Other causes of the disease were ruled out. Five months later, the patient, on his own initiative, reintroduced pravastatin and acute pancreatitis recurred after 3 days. CONCLUSION: To our knowledge this is the first report of pravastatin-induced pancreatitis and further strengthens the fact that statins may cause acute pancreatitis.

  16. Pancreatic involvement in small cell lung cancer

    International Nuclear Information System (INIS)

    Few data are available concerning incidence, clinical picture, and prognosis for pancreatic metastases of small cell lung carcinoma. In this paper we review the related literature available in English language. Although pancreatic metastases are generally asymptomatic, they can rarely produce clinical symptoms or functional abnormalities. The widespread use of multi-detector computerised tomography (CT) in contemporary medical practice has led to an increased detection of pancreatic metastases in oncology patients. Tissue diagnosis is imperative because radiological techniques alone are incapable of differentiating them from primary pancreatic tumours. Pancreatic metastases occur in the relative end stage of small cell lung cancer. The main complications of these lesions, although rare, are acute pancreatitis and obstructive jaundice. Early chemotherapy can provide a survival benefit even in patients with mild acute pancreatitis or extrahepatic biliary obstruction

  18. Imaging in the diagnosis of chronic pancreatitis

    Directory of Open Access Journals (Sweden)

    Vasile D. Balaban

    2014-12-01

    Full Text Available Chronic pancreatitis is characterised by progressive and irreversible damage of the pancreatic parenchyma and ductal system, which leads to chronic pain, loss of endocrine and exocrine functions. Clinically, pancreatic exocrine insufficiency becomes apparent only after 90% of the parenchima has been lost. Despite the simple definition, diagnosing chronic pancreatitis remains a challenge, especially for early stage disease. Because pancreatic function tests can be normal until late stages and have significant limitations, there is an incresing interest in the role of imaging techniques for the diagnosis of chronic pancreatitis. In this article we review the utility and accuracy of different imaging methods in the diagnosis of chronic pancreatitis, focusing on the role of advanced imaging (magnetic resonance imaging, endoscopic retrograde cholangiopancreatography and endoscopic ultrasound.

    2007-01-01

    BACKGROUND:Pancreatic encephalopathy (PE) is a serious complication of severe acute pancreatitis (SAP). In recent years, more and more PE cases have been reported worldwide, and the onset PE in the early stage was regarded as a poor prognosis sign of SAP, but the pathogenesis of PE in SAP still has not been clariifed in the past decade. The purpose of this review is to elucidate the possible pathogenesis of PE in SAP. DATA SOURCES:The English-language literature concern-ing PE in this review came from the Database of MEDLINE (period of 1991-2005), and the keywords of severe acute pancreatitis and pancreatic encephalopathy were used in the searching. RESULTS:Many factors were involved in the pathogenesis of PE in SAP. Pancreatin activation, excessive release of cytokines and oxygen free radicals, microcirculation abnormalities of hemodynamic disturbance, ET-1/NO ratio, hypoxemia, bacterial infection, water and electrolyte imbalance, and vitamin B1 deifciency participated in the development of PE in SAP. CONCLUSIONS:The pathogenesis of PE in SAP has not yet been fully understood. The development of PE in SAP may be a multi-factor process. To ifnd out the possible inducing factor is essential to the clinical management of PE in SAP.

    Full Text Available Discriminating between focal chronic pancreatitis and pancreatic cancer is always a challenge in clinical medicine. Contrast-enhanced endoscopic ultrasound using Doppler techniques can uniquely reveal different vascularisation patterns in pancreatic tissue alterated by chronic inflammatory processes and even allows a discrimination from pancreatic cancer. This paper will describe the basics of contrast-enhanced high mechanical index endoscopic ultrasound (CEHMI EUS and contrast enhanced low mechanical index endoscopic ultrasound (CELMI EUS and explain the pathophysiological differences of the vascularisation of chronic pancreatitis and pancreatic carcinoma. Furthermore it will discuss how to use these techniques in daily clinical practice.

    BACKGROUND: Exocrine pancreatic dysfunction has been reported in humans in the convalescent period after acute pancreatitis, but the data are scarce and conlficting. This study aimed to prospectively assess the exocrine pancreatic function in patients with acute pancreatitis at the time of their refeeding. METHODS: Fecal elastase-1 was determined on the day of refeeding in all consecutive acute pancreatitis patients with their ifrst episode of the disease. They were 75 patients including 60 (80.0%) patients with mild acute pancreatitis and 15 (20.0%) patients with severe acute pancreatitis. Etiologically 61 patients (81.3%) had biliary disease, 1 (1.3%) had alcoholic disease and 3 (4.0%) had hypertriglyceridemia. No causes of acute pancreatitis were found in the remaining 10 patients (13.3%). The mean (±SD) refeeding time after the attack of acute panereatitis was 11.2±10.2 days. RESULTS: Pathological values of FE-1 were found in 9 of the 75 patients (12.0%): 7 (9.3%) patients with mild pancreatitis and 2 (2.7%) patients with severe pancreatitis (P=1.000). The frequency of the pathological values of fecal elastase-1 was signiifcantly different from that of various etiologies of the disease (P=0.030). It was signiifcantly lower in patients with biliary pancreatitis (9.8%;P=0.035) than in one patient with alcoholic pancreatitis (P=0.126), one patient with hypertriglyceridemia-induced pancreatitis (33.3%;P=0.708), and one patient with idiopathic pancreatitis (10.0%;P=0.227). Pathological fecal elastase-1 was not signiifcantly related to sex, age or day of refeeding.CONCLUSION: Exocrine pancreatic function should be routinely assessed in patients with acute pancreatitis at the time of refeeding in order to supplement their diet with pancreatic extracts.

    Full Text Available The high mortality rate of pancreatic cancer places this uncommon malignancy quite high as a cause of cancer related deaths. Compared to other solid tumors, there is a lag in the development of new effective drugs and the actual clinical benefit remains poor over the last decade or so. The lack of therapeutic options necessitates the invention of the important molecules playing role in pancreatic carcinogenesis and the development of specific targeted therapies. Treatment advances have to be proven first in the bench before applying them at the bedside, thus why translational research is so needed.

  8. Nutritional support for acute pancreatitis.

    Pisters, P W; Ranson, J H

    1992-09-01

    The current review has summarized current data relevant to the nutritional support of patients with acute pancreatitis. Selection of the most appropriate form of nutritional support for patients with acute pancreatitis is intimately linked to a thorough understanding of the effects of various forms of enteral and parenteral nutrition on physiologic exocrine secretory mechanisms. Two basic concepts have emerged from the multiple studies that have addressed these issues to date: 1, enteral feeds should have low fat composition and be delivered distal to the ligament of Treitz to minimize exocrine pancreatic secretion and 2, parenteral substrate infusions, alone or in combinations similar to those administered during TPN, do not stimulate exocrine pancreatic secretion. From a practical standpoint, most patients with acute pancreatitis are diagnosed by nonoperative means and will manifest some degree of paralytic ileus during the early phase of the disease. Therefore, jejunal feeds are usually not a therapeutic option early in the course of this disease. On the basis of the clinical studies reviewed herein we propose general guidelines for the nutritional support of patients with acute pancreatitis: 1, most patients with mild uncomplicated pancreatitis (one to two prognostic signs) do not benefit from nutritional support; 2, nutritional support should begin early in the course of patients with moderate to severe disease (as soon as hemodynamic and cardiorespiratory stability permit); 3, initial nutritional support should be through the parenteral route and include fat emulsion in amounts sufficient to prevent essential fatty acid deficiency (no objective data exist to recommend specific amino acid formulations); 4, patients requiring operation for diagnosis or complications of the disease should have a feeding jejunostomy placed at the time of operation for subsequent enteral nutrition using a low fat formula, such as Precision HN (Sandoz, 1.3 percent calories as fat

    Full Text Available Acute pancreatitis is an acute inflammatory disease. Frequently it is a challenging condition for the surgeon and for the intensive care physician, taking into account that etiology is sometimes obscure, the pathophysiology is complex and incompletely understood, the timing of surgical treatment is still under debate and the general treatment is mostly supportive. The incidence is about 30 – 50 / 100.000 / year. In 80% of cases the disease is associated with interstitial edema, mild infiltration with inflammatory cells and intra- or peripancreatic fat necrosis. Evolution is benign and self-limited with proper treatment. The severe form occurs less frequent (15 - 20%, results in long lasting hospitalization and is associated with high mortality (30 - 40%, due to infected necrosis and multiple organ failure. Alcoholism and biliary disease account for 80% of cases. Rare etiologies of disease include metabolic factors (hypercalcemia, hyperlipoproteinemia, drug ingestion, obstructive factors (abdominal tumors, trauma, endoscopic retrograde cholecistopancreatography, and s.o., infections (viral, parasitic and hemodynamic factors. Postoperative pancreatitis is a complication after major abdominal surgery (abdominal aorta aneurism repair, extensive upper abdominal surgery, hepatic or cardiac transplant, so.. The common pathophysiological mechanism is pancreatic hypoperfusion. Acute pancreatitis is not a stable disease, being characterized by time-dependent stages with specific morphologic and clinical patterns. The terminology used to designate these stages is stated in the Ulm classification. Since the consensus Conference in Atlanta (1992 the severe form of acute pancreatitis is defined by the presence of organ dysfunction/failure or by the presence of local complications. The initiating event is the premature zymogene activation and the impairment of the exocytosis process with local consequences (ongoing tissue necrosis and general consequences

    In this Topic Highlight, the causes, diagnosis, and treat-ment of acute pancreatitis in children are discussed. Acute pancreatitis should be considered during the dif-ferential diagnosis of abdominal pain in children and requires prompt treatment because it may become life-threatening. The etiology, clinical manifestations, and course of acute pancreatitis in children are often differ-ent than in adults. Therefore, the specific features of acute pancreatitis in children must be considered. The etiology of acute pancreatitis in children is often drugs, infections, trauma, or anatomic abnormalities. Diagnosis is based on clinical symptoms(such as abdominal pain and vomiting), serum pancreatic enzyme levels, and im-aging studies. Several scoring systems have been pro-posed for the assessment of severity, which is useful for selecting treatments and predicting prognosis. The basic pathogenesis of acute pancreatitis does not greatly dif-fer between adults and children, and the treatments for adults and children are similar. In large part, our under-standing of the pathology, optimal treatment, assess-ment of severity, and outcome of acute pancreatitis in children is taken from the adult literature. However, we often find that the common management of adult pan-creatitis is difficult to apply to children. With advances in diagnostic techniques and treatment methods, severeacute pancreatitis in children is becoming better under-stood and more controllable.

    The incidence of acute pancreatitis per 100,000 of population ranges from 5 to 80. Patients suffering from hemorrhagic-necrotizing pancreatitis die in 10-24% of cases. 80% of all cases of acute pancreatitis are etiologically linked to gallstone disease immoderate alcohol consumption. As of today no specific causal treatment for acute pancreatitis exists. Elevated C-reactive protein levels above 130,mg/L can also predict a severe course of acute pancreatitis. The essential medical treatment for acute pancreatitis is the correction of hypovolemia. Prophylactic antibiotics should be restricted to patients with necrotizing pancreatitis, infected necrosis or other infectious complications. However, as premature intracellular protease activation is known to be the primary event in acute pancreatitis. Severe acute pancreatitis is characterized by an early inflammatory immune response syndrome (SIRS) and a subsequent compensatory anti-inflammatory response syndrome (CARS) contributing to severity as much as protease activation does. CARS suppresses the immune system and facilitates nosocomial infections including infected pancreatic necrosis, one of the most feared complications of the disease. A number of attempts have been made to suppress the early systemic inflammatory response but even if these mechanisms have been found to be beneficial in animal models they failed in daily clinical practice.

  12. Role of computed tomography in pancreatic trauma

    International Nuclear Information System (INIS)

    At Yonsei University Hospital from January 1984 to August 1990, computed tomographic (CT) scans of 13 patients with surgically proven pancreatic injuries after blunt abdominal trauma, including 6 pancreatic lacerations or contusions, 6 pancreatic fractures, and one post-traumatic pseudocyst, were retrospectively reviewed to determine the role and accuracy of the CT in evaluating pancreatic injury. CT can document gross pancreatic injury by showing focal or diffuse enlargement (1), area of diminished attenuation (3), separation (5), focal hematoma (2), and peripancreatic change, including peripancreatic hematoma (2), fluid collection (11), perirenal fascial thickening (10), omental and mesenteric change (5), and bowel change (2). CT correctly diagnosed pancreatic fracture in 5 cases, post-raumatic pseudocyst in 1 case, and pancreatic laceration in 3 cases in 9 of these patients. There were 4 false negative diagnoses, including 3 pancreatic lacerations and 1 pancreatic fracture. A CT is of pancreatic trauma could be difficult to diagnosis in patients who are scanned within 24 hrs after an injury or to distinguish a motion or streak artifact caused by a nasogastric tube or air-oral contrast fluid level in the stomach

    Full Text Available Elevation of pancreatic enzymes is often observed in patients admitted to intensive care units in the United States. Elevated pancreatic enzymes can occur due to acute pancreatitis or numerous non-specific reasons. Non-specific enzyme elevation can be seen in patients with head injury, acute renal failure, diabetic ketoacidosis or patients on hemodialysis. Patients with severe acute pancreatitis can be admitted to the intensive care units for intensive care or patients admitted to the intensive care units for other critical illness can develop acute pancreatitis due to a variety of reasons like ischemia, hypoperfusion, drugs or hypercalcemia. It can be a challenging task to distinguish between acute pancreatitis and non-specific enzyme elevation, especially in critically ill patients with multiple co-morbidities admitted to the intensive care units in whom historical information may not be always available. In addition, the clinical consequences of pancreatic enzyme elevation in the critically ill patients are also not very clear. This review attempts to describe the complex interplay of various factors that can lead to either pancreatic inflammation and/or pancreatic enzyme elevation in the critically ill patients along with the clinical consequences and approach to patient with pancreatic enzyme elevation in the intensive care units.

  15. Radiological observation of acute pancreatitis

    International Nuclear Information System (INIS)

    The radiologic study of the pancreas oriented in the upper retroperitoneal space is difficult because the specific density of this viscus is the same as that of its surrounding tissue. so that it cannot be visualized directly. Furthermore, it is one of the few viscera in the abdomen which cannot be outlined by a contrast medium. In the abdomen, the diagnosis of acute pancreatitis is very important since the present treatment of this disease is conservative, which emergency laparatomy is indicated in most other abdominal crisaes. However, the diagnosis of acute pancreatitis cannot be made by roentgen studies alone, yet such studies can at times confirm an uncertain clinical diagnosis when evaluated with clinical findings and can occasionally alert the unsuspecting clinician to the possible presence of this disease. Because a radiologic examination plays such an important role in the differential diagnosis of the acute abdomen and at present augmenting interest for pancreatic disease, we present this discussion in order to focus attention on the radiologic features of acute pancreatitis.1. From Nov. 1968 to June 1978, roentgenologic studies of 275 patients diagnosed as acute pancreatitis were reviewed. 2. In this series, the important findings on the chest roentgenograms of 275 cases were as follows. 1) Fifty-five cases (20.0%) of these represented pleural effusion. 2) Platelike atelectasis at the lung bases was noted in 44 cases (16.0%). 3) There was elevation of the diaphragm in 33 cases (12.0%). 3. The significant findings on the simple abdomen of 247 cases were as follows. 1) The presence of a sentinel loop occurred in 168 cases (68.0%). 2) Colon 'cut-off' sign was noted in 106 cases (42.9%). 3) Obliteration of psoas shadows in 8 cases (3.2%). 4) Gastrocolic separation in 4 cases (1.6%). 4. One hundred and seventy-five barium meal studies of the stomach and duodenum were available for review.

    Surgical treatment is not commonly recommended in the management of autoimmune pancreatitis. The article describes a dilemma in diagnostics and treatment of a 68-year old man with the mass in the head of the pancreas that mimicked pancreatic cancer and that was diagnosed as a type 1 autoimmune pancreatitis (IgG4-related pancreatitis) after a surgical resection. Diagnosis of the autoimmune pancreatitis is a real clinical challenge, as in the current diagnostic criteria exists some degree of overlap in the findings between autoimmune pancreatitis and pancreatic cancer (indicated by the similarity in radiologic findings, elevation of IgG4, sampling errors in pancreatic biopsy, and the possibility of synchronous autoimmune pancreatitis and pancreatic cancer). Despite the generally accepted corticosteroids as the primary treatment modality in autoimmune pancreatitis, we believe that surgical resection remains necessary in a specific subgroup of patients with autoimmune pancreatitis (Fig. 4, Ref. 37).

    Autoimmune pancreatitis is a disease characterized by specific pathological features, different from those of other forms of pancreatitis, that responds dramatically to steroid therapy. The pancreatic parenchyma may be diffusely or focally involved with the possibility of a low-density mass being present at imaging, mimicking pancreatic cancer. Clinically, the most relevant problems lie in the diagnosis of autoimmune pancreatitis and in distinguishing autoimmune pancreatitis from pancreatic cancer. Since in the presence of a pancreatic mass the probability of tumour is much higher than that of pancre-atitis, the physician should be aware that in focal autoimmune pancreatitis the first step before using steroids is to exclude pancreatic adenocarcinoma. In this review, we briefly analyse the strategies to be followed for a correct diagnosis of autoimmune pancreatitis.

    Acute pancreatitis is a life-threatening inflammatory disease characterized by abdominal pain of unknown etiology. Trypsin, a key mediator of pancreatitis, causes inflammation and pain by activating protease-activated receptor 2 (PAR2), but the isoforms of trypsin that cause pancreatitis and pancreatic pain are unknown.

    Full Text Available CONTEXT: Acute pancreatitis during pregnancy is rare and commonly occurs in association with biliary disease. Preeclampsia is associated with microvascular abnormalities that may involve cerebral, placental, hepatic, renal and splanchnic circulation and rarely can cause acute pancreatitis. CASE REPORT: A case of acute pancreatitis in a patient with preeclampsia-eclampsia where the diagnosis was missed initially that resulted in a protracted course and development of organized pancreatic necrosis. The pancreatic necrosis resolved with conservative management over 8 weeks. CONCLUSIONS: The development of severe hypoalbuminemia, out of proportion to proteinuria, hypocalcemia and findings of capillary leak should alert the physician to search for other inflammatory causes, including acute pancreatitis so that early and effective management be given to avoid complications.

    2011-01-01

    There is an ongoing discussion on how to diagnose a hyperechogenic pancreas and what is the clinical signifi-cance of diffusely hyperechogenic pancreas. Computerized tomography and magnetic resonance imaging are the more appropriate methods to diagnose pancreatic hyper-echogenicity when compared with transcutaneous or en-doscopic ultrasound examination. More importantly, pan-creatic hyperechogenicity may not be a certain indicator of pancreatic fat infiltration. Even if it is true, we do not know the clinical significances of pancreatic fat accumulation. Some suggested that excess fat in the pancreas is associ-ated with chronic pancreatitis. However, several histologi-cal studies on human alcoholic chronic pancreatitis did not prove the presence of fatty pancreas in such cases. Thus, except for aging, it is very rare to have truly steatotic pan-creas in the absence of certain human diseases.

  1. Transcatheter Embolization of Pseudoaneurysms Complicating Pancreatitis

    International Nuclear Information System (INIS)

    Purpose: To evaluate the therapeutic role of angiography in patients with pseudoaneurysms complicating pancreatitis. Methods: Thirteen symptomatic pseudoaneurysms were treated in nine patients with pancreatitis. Eight patients had chronic pancreatitis and pseudocyst and one had acute pancreatitis. Clinical presentation included gastrointestinal bleeding in seven patients and epigastric pain without bleeding in two. All patients underwent transcatheter embolization. Results: Transcatheter embolization resulted in symptomatic resolution in all patients. Rebleeding occurred in two patients, 18 and 28 days after embolization respectively, and was successfully treated by repeated emnbolization. One patient with severe pancreatitis died from sepsis 28 days after embolization. Follow-up was then available for eight patients with no relapse of bleeding after a mean follow-up of 32 months (range 9-48 months). Conclusion: Transcatheter embolization is safe and effective in the management of pseudoaneurysms complicating pancreatitis

  2. Pancreatic cancer: Pathogenesis, prevention and treatment

    International Nuclear Information System (INIS)

    Pancreatic cancer is the fourth leading cause of cancer death in the United States with a very low survival rate of 5 years. To better design new preventive and/or therapeutic strategies for the fight against pancreatic cancer, the knowledge of the pathogenesis of pancreatic cancer at the molecular level is very important. It has been known that the development and the progression of pancreatic cancer are caused by the activation of oncogenes, the inactivation of tumor suppressor genes, and the deregulation of many signaling pathways among which the EGFR, Akt, and NF-κB pathways appear to be most relevant. Therefore, the strategies targeting EGFR, Akt, NF-κB, and their downstream signaling could be promising for the prevention and/or treatment of pancreatic cancer. In this brief review, we will summarize the current knowledge regarding the pathogenesis, prevention, and treatment of pancreatic cancer

    While the gastric involvement of pancreatic cancer is occasionally observed as the result of direct invasion, hematogenous gastric metastasis is rare. A 72-year-old Japanese male presented with general fatigue, pollakiuria, and thirst. Computed tomography revealed a 4.6-cm solid mass in the pancreatic tail and a 4.2-cm multilocular cystic mass in the pancreatic head with multiple liver and lymphatic metastasis. Notably, two solid masses were detected in the gastric wall of the upper body and the antrum; both were separated from the primary pancreatic cancer and seemed to be located in the submucosal layer. Esophagogastroduodenoscopy revealed a submucosal tumor with a normal mucosa in the posterior wall of the upper body of the stomach, suggesting the gastric hematogenous metastasis of pancreatic cancer. The suspected diagnosis was unresectable pancreatic cancer with multiple metastases that was concomitant with the intraductal papillary mucinous neoplasm of the pancreas.

    Full Text Available Acute biliary pancreatitis is one of the major causes of acute pancreatitis.Gallstones, biliary sludge and microlithiasis, especially in pancreatitis without detectable reason, can be the cause of acute pancreatitis. Acute biliary pancreatitis has many controversions in the literature, and its classification and guidelines are being updated very frequently. Atlanta classifications which determine the definitions and guidelines about acute pancreatitis were renewed and published in 2013. It has various clinical aspects, ranging from a mild form which is easily treated, to a severe form that causes complications leading to mortality. The pathogenesis of this disease has not been fully elucidated and several theories have been suggested. New scoring systems and laboratory methods such as proteomics have been suggested for both diagnosis and to predict disease severity, and research on these topics is still in progress. Novel therapeutic approaches with technological developments such as ERCP, ES, MRCP, and EUS are also suggested.

    International Nuclear Information System (INIS)

    Perfusion computed tomography (P-CT) is now available for the analysis of pancreatic blood flow. The aim of this study was to clarify pancreatic blood perfusion in AIP patients and the changes after steroid treatment. Color map imaging of P-CT and pancreatic time CT density curve (TDC) demonstrated that the pancreatic blood flow was attenuated in AIP patients. Pancreatic volumetric blood flow FV values of 11 AIP patients (82.7/min) were significantly lower than those of 12 normal controls (163.5/min, p=0.0006). AIP patients received steroid treatment and were re-examined, of these, 9 patients showed significantly elevated FV values after treatment (76.2/min and 109.8/min, p=0.0391, respectively). However, the changes of the values after the treatment differed in varying degrees among the individuals. P-CT is a useful method for the analysis of the blood flow in pancreatic diseases. (author)

Main morphological changes were manifested as: the concentric periductal fibrosis and local stenosis, the dysplastic changes of ductal epithelium with low level of proliferative activity and caspase -3 expression (in patients with pancreatic duct dilation; the cystic dilation of small and medium-sized intralobular ducts with low levels of Ki-67 and caspase-3 expression (in patients with ductal hypertension, but without pancreatic duct dilation; pancreatic intraepithelial neoplasia (PanIN is accompanied with the excessive nuclear Ki-67 expression and the low cytoplasmic caspase-3 levels. Conclusion. Structural remodeling of the pancreatic ductal system during chronic pancreatitis were not associated with rising of Ki-67 or Caspase-3 expression levels, unless in case of pancreatic intraepithelial neoplasia.

    Aim: To retrospectively establish the most frequently encountered diagnoses in patients with pancreatic calcifications and to investigate whether the association of certain findings could be helpful for diagnosis. Materials and methods: One hundred and three patients were included in the study. The location and distribution of calcifications; presence, nature, and enhancement pattern of pancreatic lesions; pancreatic atrophy and ductal dilatation were recorded. Differences between patients with chronic pancreatitis and patients with other entities were compared by using Fisher's exact test. Results: Patients had chronic pancreatitis (n = 70), neuroendocrine tumours (n = 14), intraductal papillary mucinous neoplasm (n = 11), pancreatic adenocarcinoma (n = 4), serous cystadenoma (n = 4). Four CT findings had a specificity of over 60% for the diagnosis of chronic pancreatitis: parenchymal calcifications, intraductal calcifications, parenchymal atrophy, and cystic lesions. When at least two of these four criteria were used in combination, 54 of 70 (77%) patients with chronic pancreatitis could be identified, but only 17 of 33 (51%) patients with other diseases. When at least three of these four criteria were present, a specificity of 79% for the diagnosis of chronic pancreatitis was achieved. Conclusion: Certain findings are noted more often in chronic pancreatitis than in other pancreatic diseases. The presence of a combination of CT findings can suggest chronic pancreatitis and be helpful in diagnosis.

    International Nuclear Information System (INIS)

    Purpose: Autoimmune pancreatitis is a unique form of chronic pancreatitis characterized by a variety of extra-pancreatic involvements which are frequently misdiagnosed as lesions of corresponding organs. The purpose of this study was to clarify the diagnostic imaging features of extra-pancreatic lesions associated with autoimmune pancreatitis. Materials and methods: We retrospectively analyzed diagnostic images of 90 patients with autoimmune pancreatitis who underwent computer-assisted tomography, magnetic resonance imaging, and/or gallium-67 scintigraphy before steroid therapy was initiated. Results: AIP was frequently (92.2%) accompanied by a variety of extra-pancreatic lesions, including swelling of lachrymal and salivary gland lesions (47.5%), lung hilar lymphadenopathy (78.3%), a variety of lung lesions (51.2%), wall thickening of bile ducts (77.8%), peri-pancreatic or para-aortic lymphadenopathy (56.0%), retroperitoneal fibrosis (19.8%), a variety of renal lesions (14.4%), and mass lesions of the ligamentum teres (2.2%). Characteristic findings in CT and MRI included lymphadenopathies of the hilar, peri-pancreatic, and para-aortic regions; wall thickening of the bile duct; and soft tissue masses in the kidney, ureters, aorta, paravertebral region, ligamentum teres, and orbit. Conclusions: Recognition of the diagnostic features in the images of various involved organs will assist in the diagnosis of autoimmune pancreatitis and in differential diagnoses between autoimmune pancreatitis-associated extra-pancreatic lesions and lesions due to other pathologies.

    Emphysematous pancreatitis is a rare variant of severe acute pancreatitis characterized by gas formation within and around the pancreas. Early radiology detection of retroperitoneal gas in patients with pancreatitis is important in view of the high morbidity and mortality associated with this condition. Computed tomography is the imaging modality of choice. It is both highly sensitive and specific in the detection of abnormal gas and is well-suited to reliably depict the anatomical location and extent of the gas.

  18. Hedgehog signaling and therapeutics in pancreatic cancer.

    LENUS (Irish Health Repository)

    Kelleher, Fergal C

    2012-02-01

    OBJECTIVE: To conduct a systematic review of the role that the hedgehog signaling pathway has in pancreatic cancer tumorigenesis. METHOD: PubMed search (2000-2010) and literature based references. RESULTS: Firstly, in 2009 a genetic analysis of pancreatic cancers found that a core set of 12 cellular signaling pathways including hedgehog were genetically altered in 67-100% of cases. Secondly, in vitro and in vivo studies of treatment with cyclopamine (a naturally occurring antagonist of the hedgehog signaling pathway component; Smoothened) has shown that inhibition of hedgehog can abrogate pancreatic cancer metastasis. Thirdly, experimental evidence has demonstrated that sonic hedgehog (Shh) is correlated with desmoplasia in pancreatic cancer. This is important because targeting the Shh pathway potentially may facilitate chemotherapeutic drug delivery as pancreatic cancers tend to have a dense fibrotic stroma that extrinsically compresses the tumor vasculature leading to a hypoperfusing intratumoral circulation. It is probable that patients with locally advanced pancreatic cancer will derive the greatest benefit from treatment with Smoothened antagonists. Fourthly, it has been found that ligand dependent activation by hedgehog occurs in the tumor stromal microenvironment in pancreatic cancer, a paracrine effect on tumorigenesis. Finally, in pancreatic cancer, cells with the CD44+CD24+ESA+ immunophenotype select a population enriched for cancer initiating stem cells. Shh is increased 46-fold in CD44+CD24+ESA+ cells compared with normal pancreatic epithelial cells. Medications that destruct pancreatic cancer initiating stem cells are a potentially novel strategy in cancer treatment. CONCLUSIONS: Aberrant hedgehog signaling occurs in pancreatic cancer tumorigenesis and therapeutics that target the transmembrane receptor Smoothened abrogate hedgehog signaling and may improve the outcomes of patients with pancreatic cancer.

    2014-01-01

    Pancreatic cancer carries a poor prognosis as most patients present with advanced disease and preferred chemotherapy regimens offer only modest effects on survival. Risk factors include smoking, obesity, heavy alcohol, and chronic pancreatitis. Pancreatic cancer has a complex relationship with diabetes, as diabetes can be both a risk factor for pancreatic cancer and a result of pancreatic cancer. Insulin, insulin-like growth factor-1 (IGF-1), and certain hormones play an important role in promoting neoplasia in diabetics. Metformin appears to reduce risk for pancreatic cancer and improve survival in diabetics with pancreatic cancer primarily by decreasing insulin/IGF signaling, disrupting mitochondrial respiration, and inhibiting the mammalian target of rapamycin (mTOR) pathway. Other potential anti-tumorigenic effects of metformin include the ability to downregulate specificity protein transcription factors and associated genes, alter microRNAs, decrease cancer stem cell proliferation, and reduce DNA damage and inflammation. Here, we review the most recent knowledge on risk factors and treatment of pancreatic cancer and the relationship between diabetes, pancreatic cancer, and metformin as a potential therapy.

  1. Considerations for the grade IIIb pancreatic trauma

    International Nuclear Information System (INIS)

    Pancreatic duct disruption accompanied by pancreatic trauma is very severe. Endoscopic retrograde pancreatography (ERP) is considered the main diagnostic modality. However, it is invasive and can be associated with significant complications. We diagnosed pancreatic trauma based on only Computed tomography (CT) scan data. We operated based on specific signs of pancreatic injuries on CT scans, such as edema or hematoma of the pancreatic parenchyma, fractures or lacerations of the pancreas, active hemorrhage and, in all cases, there were main pancreatic duct injuries. Certain drainage of the pancreatic juice is necessary for pancreatic duct disruption. The operation method was selected according to the location of the damage. If it is at all possible pancreas preserving surgery should be performed. It is necessary to select the operation according to the patient's age and general condition, the cause of the injury, the range of the injury, and the experience of the surgeon. When the main duct injury was not certain, ERP during the operation was very useful. We report on a method of endoscopically treating a pseudocyst, which has adhered to the stomach, secondary to pancreatic main duct disruption. Transgastric placement of a stent into the pseudocyst is possible in restricted cases. (author)

  2. Diffuse pancreatic ductal adenocarcinoma: Characteristic imaging features

    International Nuclear Information System (INIS)

    Purpose: To evaluate imaging findings of diffuse pancreatic ductal adenocarcinoma. Materials and methods: We included 14 patients (4 men and 10 women; mean age, 64.5 years) with diffuse pancreatic ductal adenocarcinoma on the basis of retrospective radiological review. Two radiologists retrospectively reviewed 14 CT scans in consensus with respect to the following: tumor site, peripheral capsule-like structure, dilatation of intratumoral pancreatic duct, parenchymal atrophy, and ancillary findings. Eight magnetic resonance (MR) examinations with MR cholangiopancreatography (MRCP) and seven endoscopic retrograde cholangiopancreatography (ERCP) were also reviewed, focusing on peripheral capsule-like structure and dilatation of intratumoral pancreatic duct. Results: CT revealed tumor localization to the body and tail in 11 (79%) patients and peripheral capsule-like structure in 13 (93%). The intratumoral pancreatic duct was not visible in 13 (93%). Pancreatic parenchymal atrophy was not present in all 14 patients. Tumor invasion of vessels was observed in all 14 patients and of neighbor organs in 8 (57%). On contrast-enhanced T1-weighted MR images, peripheral capsule-like structure showed higher signal intensity in five patients (71%). In all 11 patients with MRCP and/or ERCP, the intratumoral pancreatic duct was not dilated. Conclusion: Diffuse pancreatic ductal adenocarcinoma has characteristic imaging findings, including peripheral capsule-like structure, local invasiveness, and absence of both dilatation of intratumoral pancreatic duct and parenchymal atrophy

    Pancreatic regeneration (PR) is an interesting phenomenon that could provide clues as to how the control of diabetes mellitus might be achieved. Due to the different regenerative abilities of the pancreas and liver, the molecular mechanism responsible for PR is largely unknown. In this review, we describe five representative murine models of PR and thirteen humoral mitogens that stimulate β-cell proliferation. We also describe pancreatic ontogenesis, including the molecular transcriptional differences between α-cells and β-cells. Furthermore, we review 14 murine models which carry defects in genes related to key transcription factors for pancreatic ontogenesis to gain further insight into pancreatic development.

    Somatostatin may play an important role in the regulation of cancer growth including pancreatic cancer by interaction with somatostatin receptors (SSTRs) on the cell surface. Five SSTRs were cloned, and the function of these SSTRs is addressed in this review. SSTR-2, SSTR-5, and SSTR-1 are thought to play major roles in inhibiting pancreatic cancer growth both in vitro and in vivo. SSTR-3 may be involved in mediating apoptosis, but the role of SSTR-4 is not clear. In most pancreatic cancers, functional SSTRs are absent. Reintroduction of SSTR genes has been shown to inhibit pancreatic cancer growth in cell cultures and animal models. PMID:15706439

    Full Text Available Abstract Background Acute pancreatitis rarely complicates pregnancy. Although most pregnant women with acute pancreatitis have associated gallstones, less common causes such as drugs have been reported. Case presentation We report the case of a 34-year-old woman who underwent medical abortion with mifepristone and gemeprost and received codeine as pain-relief during the induction of abortion. She developed a severe acute necrotizing pancreatitis which required 14 days of intensive care. Other possible etiological factors, i.e. gallstone, alcohol intake and hyperlipidemia, were excluded. Conclusions The reported case of acute pancreatitis was most likely drug-induced.

    Pancreatic cancer carries a poor prognosis as most patients present with advanced disease and preferred chemotherapy regimens offer only modest effects on survival. Risk factors include smoking, obesity, heavy alcohol, and chronic pancreatitis. Pancreatic cancer has a complex relationship with diabetes, as diabetes can be both a risk factor for pancreatic cancer and a result of pancreatic cancer. Insulin, insulin-like growth factor-1 (IGF-1), and certain hormones play an important role in promoting neoplasia in diabetics. Metformin appears to reduce risk for pancreatic cancer and improve survival in diabetics with pancreatic cancer primarily by decreasing insulin/IGF signaling, disrupting mitochondrial respiration, and inhibiting the mammalian target of rapamycin (mTOR) pathway. Other potential anti-tumorigenic effects of metformin include the ability to downregulate specificity protein transcription factors and associated genes, alter microRNAs, decrease cancer stem cell proliferation, and reduce DNA damage and inflammation. Here, we review the most recent knowledge on risk factors and treatment of pancreatic cancer and the relationship between diabetes, pancreatic cancer, and metformin as a potential therapy.

    Background Pancreatic cancer is one of the most lethal human cancers with a very low survival rate of 5 years.Conventional cancer treatments including surgery, radiation, chemotherapy or combinations of these show little effect on this disease. Several proteins have been proved critical to the development and the progression of pancreatic cancer.The aim of this study was to investigate the effect of resveratrol on apoptosis in pancreatic cancer cells.Methods Several pancreatic cancer cell lines were screened by resveratrol, and its toxicity was tested by normal pancreatic cells. Western blotting was then performed to analyze the molecular mechanism of resveratrol induced apoptosis of pancreatic cancer cell lines.Results In the screened pancreatic cancer cell lines, capan-2 and colo357 showed high sensitivity to resveratrol induced apoptosis. Resveratrol exhibited insignificant toxicity to normal pancreatic cells. In resveratrol sensitive cells,capan-2 and colo357, the activation of caspase-3 was detected and showed significant caspase-3 activation upon resveratrol treatment; p53 and p21 were also detected up-regulated upon resveratrol treatment.Conclusion Resveratrol provides a promising anti-tumor stratagy to fight against pancreatic cancer.

    1977-08-01

    Retrospective and prospective studies were done to evaluate the efficacy of oral cholecystography (OCG) performed before hospital discharge on alcoholic patients with acute pancreatitis. In the retrospective study, OCG adequately opacified the gallbladder in 21 of 26 patients (81%). Of the 5 patients with inadequate opacification, 1 was jaundiced at the time of OCG; the other 4 had OCG before resumption of solid food. In the prospective study, OCG done in nonjaundiced patients shortly after resumption of food yielded adequate opacification in 19 of 21 patients (90%) without gallstones. We conclude that in nonjaundiced alcoholic patients with acute pancreatitis not caused by gallstones, OCG performed after resumption of a solid diet and before hospital discharge is usually successful in opacifying the gallbladder.

  11. Pancreatic Castleman's disease: MR findings

    International Nuclear Information System (INIS)

    Castleman's disease can involve a number of organs/tissues but generally affects the mediastinum. Occurrence of Castleman's disease in the pancreas in either form of the disease, the hyaline vascular or the plasma-cell type, is very rare, with only a few case reports in which the imaging findings were described. The MR imaging of pancreatic Castleman's disease has not been previously reported, to our knowledge. We submit the MRI findings in a patient with the plasma-cell-type of castleman's disease, which presented as an isolated smoothly marginated pancreatic mass, hypointense on T1-weighted fat-suppressed images, isointense on T2-weighted sequences, and that after contrast material injection showed peripheral rim enhancement during the arterial phase.

  12. Surgery of malignant pancreatic tumors

    International Nuclear Information System (INIS)

    Ductal adenocarcinoma is the most common malignant tumor of the pancreas. Despite great efforts in basic and clinical pancreatic cancer research, the prognosis remains poor with an overall 5-year survival rate of less than 5%. Complete surgical resection represents the only curative treatment option and 5-year survival rates of 20-25% can be achieved following curative resection and adjuvant chemotherapy. Although pancreatic surgery is considered one of the most technically demanding and challenging procedures, there has been constant progress in surgical techniques and advances in perioperative care with a modern interdisciplinary approach including anesthesiology, oncology, radiology and nursing. This has reduced morbidity and especially mortality rates in high-volume centers. Among extended resection procedures multivisceral and venous resections are technically feasible and should be considered if a complete tumor resection can be achieved. Multimodal regimens have shown promising results, however, only adjuvant chemotherapy is supported by solid evidence from randomized controlled trials. (orig.)

    Abdominal pain is a major clinical problem in patients with chronic pancreatitis.The cause of pain is usually multifactorial with a complex interplay of factors contributing to a varying degree to the pain in an individual patient and,therefore,a rigid standardized approach for pain control tends to lead to suboptimal results.Pain management usually proceeds in a stepwise approach beginning with general lifestyle recommendations,low fat diet,alcohol and smoking cessation are encouraged.Analgesics alone are needed in almost all patients.Maneuvers aimed at suppression of pancreatic secretion are routinely tried.Patients with ongoing symptoms may be candidates for more invasive options such as endoscopic therapy,and resective or drainage surgery.The role of pain modifying agents (antidepressants,gabapentin,peregabalin),celiac plexus block,antioxidants,octreotide and total pancreatectomy with islet cell auto transplantation remains to be determined.

    Radiotherapy is commonly offered to patients with pancreatic malignancies although its ultimate utility is compromised since the pancreas is surrounded by exquisitely radiosensitive normal tissues, such as the duodenum, stomach, jejunum, liver, and kidneys. Proton radiotherapy can be used to create dose distributions that conform to tumor targets with significant normal tissue sparing. Because of this, protons appear to represent a superior modality for radiotherapy delivery to patients with unresectable tumors and those receiving postoperative radiotherapy. A particularly exciting opportunity for protons also exists for patients with resectable and marginally resectable disease. In this paper, we review the current literature on proton therapy for pancreatic cancer and discuss scenarios wherein the improvement in the therapeutic index with protons may have the potential to change the management paradigm for this malignancy.

  15. Genetic alterations in pancreatic carcinoma

    2003-01-01

    Full Text Available Abstract Cancer of the exocrine pancreas represents the fifth leading cause of cancer death in the Western population with an average survival after diagnosis of 3 to 6 months and a five-year survival rate under 5%. Our understanding of the molecular carcinogenesis has improved in the last few years due to the development of novel molecular biological techniques. Pancreatic cancer is a multi-stage process resulting from the accumulation of genetic changes in the somatic DNA of normal cells. In this article we describe major genetic alterations of pancreatic cancer, mutations in the proto-oncogene K-RAS and the tumor suppressors INK4A, TP53 and DPC4/SMAD4. The accumulation of these genetic changes leads to a profound disturbance in cell cycle regulation and continuous growth. The knowledge of the underlying molecular mechanisms will offer new therapeutic and diagnostic options and hopefully improve the outcome of this aggressive disease.

    Full Text Available A majority of pancreatic cancer patients present with pain at the time of diagnosis. Pain management can be challenging in light of the aggressive nature of this cancer. Apart from conventional pharmacotherapy, timely treatment with neurolytic celiac plexus block (NCPB has been shown to be of benefit. NCPB has demonstrated efficacious pain control in high quality studies with analgesic effects lasting one to two months. NCPB has also shown to decrease the requirements of narcotics, and thus decrease opioid related side effects. Another option for the control of moderate to severe pain is intrathecal therapy (IT. Delivery of analgesic medications intrathecally allows for lower dosages of medications and thus reduced toxicity. Both of the above mentioned interventional procedures have been shown to have low complication rates, and be safe and effective. Ultimately, comprehensive pancreatic cancer pain management necessitates understanding of pain mechanisms and delivery of sequential validated therapeutic interventions within a multidisciplinary patient care model.

    Full Text Available Burkitt lymphoma (BL is a highly aggressive B cell lymphoma, presenting in extranodal sites or as an acute leukemia. Three clinical variants of BL are recognized: endemic BL, sporadic BL and immunodeficiency associated BL. Sporadic BL is seen worldwide, mainly in children and young adults involving the abdominal organs mostly the ileocaecal area. Pancreatic involvement is rare. The authors report a unique case of abdominal Burkitt lymphoma, initially diagnosed and treated as acute pancreatitis. Clinically, the patient presented severe abdominal pain and vomiting. Imaging findings were suggestive of inflammatory involvement of the pancreas, heading treatment towards this hypothesis. Unfortunately, the patient died during the diagnostic work up, and the autopsy findings demonstrated advanced Burkitt lymphoma with extensive involvement of pancreatic parenchyma and other organs within the abdominal cavity. Once Burkitt lymphoma is a potentially curable disease, early diagnosis is crucial for better outcomes.

    Background. Plasmablastic lymphoma (PBL) is a rare B-cell neoplasm. It predominantly occurs in the oral cavity of human immunodeficiency virus (HIV)-positive patients and exhibits a highly aggressive clinical behavior. Case Presentation. We describe an unusual case of a 37-year-old HIV-positive male who presented with acute pancreatitis secondary to multiple peripancreatic masses compressing the pancreas. Histopathological examination of the lesions showed diffuse and cohesive pattern of large B-cells resembling immunoblasts or plasmablasts. The neoplastic cells were positive for BOB1 and MUM1, partially positive for CD79a, and negative for CD20, CD56, CD138, CD3, CD5, AE1/AE3, and HHV8. Epstein-Barr virus-encoded RNA in situ hybridization was positive. These features were consistent with PBL. The patient was initiated on cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) chemotherapy, demonstrating a striking response. Conclusion. To our research, this is the first report of PBL with the initial presentation of acute pancreatitis. The findings in this case suggest that PBL should be included in the differential diagnosis of pancreatic and peripancreatic tumors. PMID:27034868

    The aim of the present review is to summarize the current knowledge regarding pharmacological prevention and treatment of acute pancreatitis (AP)based on experimental animal models and clinical trials.Somatostatin (SS) and octreotide inhibit the exocrine production of pancreatic enzymes and may be useful as prophylaxis against Post Endoscopic retrograde cholangiopancreatography Pancreatitis (PEP). The protease inhibitor Gabexate mesilate (GM) is used routinely as treatment to AP in some countries, but randomized clinical trials and a meta-analysis do not support this practice. Nitroglycerin (NGL) is a nitrogen oxide (NO) donor, which relaxes the sphincter of Oddi.Studies show conflicting results when applied prior to ERCP and a large multicenter randomized study is warranted. Steroids administered as prophylaxis against PEP has been validated without effect in several randomized trials. The non-steroidal anti-inflammatory drugs (NSAID) indomethacin and diclofenac have in randomized studies showed potential as prophylaxis against PEP. Interleukin 10 (IL-10) is a cytokine with anti-inflammatory properties but two trials testing IL-10 as prophylaxis to PEP have returned conflicting results.Antibodies against tumor necrosis factor-alpha (TNF-α)have a potential as rescue therapy but no clinical trials are currently being conducted. The antibiotics betalactams and quinolones reduce mortality when necrosis is present in pancreas and may also reduce incidence of infected necrosis. Evidence based pharmacological treatment of AP is limited and studies on the effect of potent anti-inflammatory drugs are warranted.

    The outlook for patients with pancreatic cancer has been grim. There have been major advances in the surgical treatment of pancreatic csncer, leading to a drsmatic reduction in post-operative mortality from the development of high volume specialized centres. This stimulated the study of adjuvant and neoadjuvant treatments in pancreatic cancer including chemoradiotherapy and chemotherapy. Initial protocols have been based on the original but rather small GITSG study first reported in 1985. There have been two large European trials totalling over 600 patients (EORTC and ESPAC-1) that do not support the use of chemoradiation as adjuvant therapy. A second major finding from the ESPAC-1 trial (541 patients randomized) was some but not conclusive evidence for a survival benefit associated with chemotherapy. A third major finding from the ESPAC-1 trial was that the quality of life was not affected by the use of adjuvant treatments compared to surgery alone.The ESPAC-3 trial aims to assess the definitive use of adjuvant chemotherapy in a randomized controlled trial of 990 patients.

  14. Recurrent Acute Pancreatitis Possibly Induced by Atorvastatin and Rosuvastatin. Is Statin Induced Pancreatitis a Class Effect?

    Directory of Open Access Journals (Sweden)

    Dolan JG

    2004-11-01

    Full Text Available CONTEXT: Few data exist about the incidence of drug-induced pancreatitis in the general population. Drugs are related to the etiology of pancreatitis in about 1.4-2% of cases. While statins are generally well tolerated they have been known to be associated with pancreatitis. Acute pancreatitis has been reported in a few cases treated with atorvastatin, fluvastatin, lovastatin, simvastatin and pravastatin. CASE REPORT: We report the case of a 77-year-old patient who developed acute pancreatitis after treatment with rosuvastatin, which resolved on withdrawal of the medication. She had a similar episode of pancreatitis a year ago precipitated by atorvastatin, which resolved on withdrawal. Extensive workup on both occasions failed to reveal any other etiology for the pancreatitis. CONCLUSION: To our knowledge this is the first report of rosuvastatin-induced pancreatitis. The occurrence of pancreatitis with two different statins in our patient argues that statins induced pancreatitis may be a class-effect of statins. With statin prescriptions on the rise clinicians need to be aware of this complication of statin treatment and remember that the newest statin, rosuvastatin is not dissimilar to the other statins in causing pancreatitis.

  15. Management of pain in chronic pancreatitis with emphasis on exogenous pancreatic enzymes.

    Hobbs, Paul M; Johnson, William G; Graham, David Y

    2016-08-01

    One of the most challenging issues arising in patients with chronic pancreatitis is the management of abdominal pain. Many competing theories exist to explain pancreatic pain including ductal hypertension from strictures and stones, increased interstitial pressure from glandular fibrosis, pancreatic neuritis, and ischemia. This clinical problem is superimposed on a background of reduced enzyme secretion and altered feedback mechanisms. Throughout history, investigators have used these theories to devise methods to combat chronic pancreatic pain including: Lifestyle measures, antioxidants, analgesics, administration of exogenous pancreatic enzymes, endoscopic drainage procedures, and surgical drainage and resection procedures. While the value of each modality has been debated over the years, pancreatic enzyme therapy remains a viable option. Enzyme therapy restores active enzymes to the small bowel and targets the altered feedback mechanism that lead to increased pancreatic ductal and tissue pressures, ischemia, and pain. Here, we review the mechanisms and treatments for chronic pancreatic pain with a specific focus on pancreatic enzyme replacement therapy. We also discuss different approaches to overcoming a lack of clinical response update ideas for studies needed to improve the clinical use of pancreatic enzymes to ameliorate pancreatic pain.

    Background and aims Peripancreatic fat necrosis occurs frequently in necrotising pancreatitis. Distinguishing markers from mediators of severe acute pancreatitis (SAP) is important since targeting mediators may improve outcomes. We evaluated potential agents in human pancreatic necrotic collections (NCs), pseudocysts (PCs) and pancreatic cystic neoplasms and used pancreatic acini, peripheral blood mononuclear cells (PBMC) and an acute pancreatitis (AP) model to determine SAP mediators. Methods We measured acinar and PBMC injury induced by agents increased in NCs and PCs. Outcomes of caerulein pancreatitis were studied in lean rats coadministered interleukin (IL)-1β and keratinocyte chemoattractant/growth-regulated oncogene, triolein alone or with the lipase inhibitor orlistat. Results NCs had higher fatty acids, IL-8 and IL-1β versus other fluids. Lipolysis of unsaturated triglyceride and resulting unsaturated fatty acids (UFA) oleic and linoleic acids induced necro-apoptosis at less than half the concentration in NCs but other agents did not do so at more than two times these concentrations. Cytokine coadministration resulted in higher pancreatic and lung inflammation than caerulein alone, but only triolein coadministration caused peripancreatic fat stranding, higher cytokines, UFAs, multisystem organ failure (MSOF) and mortality in 97% animals, which were prevented by orlistat. Conclusions UFAs, IL-1β and IL-8 are elevated in NCs. However, UFAs generated via peripancreatic fat lipolysis causes worse inflammation and MSOF, converting mild AP to SAP. PMID:25500204

  17. Necrotizing Pancreatitis: A Review of Multidisciplinary Management

    Full Text Available The objective of this review is to summarize the current state of the art of the management of necrotizing pancreatitis, and to clarify some confusing points regarding the terminology and diagnosis of necrotizing pancreatitis, as these points are essential for management decisions and communication between providers and within the literature. Acute pancreatitis varies widely in its clinical presentation. Despite the publication of the Atlanta guidelines, misuse of pancreatitis terminology continues in the literature and in clinical practice, especially regarding the local complications associated with severe acute pancreatitis. Necrotizing pancreatitis is a manifestation of severe acute pancreatitis associated with significant morbidity and mortality. Diagnosis is aided by pancreas-protocol computed tomography or magnetic resonance imaging, ideally 72 h after onset of symptoms to achieve the most accurate characterization of pancreatic necrosis. The extent of necrosis correlates well with the incidence of infected necrosis, organ failure, need for debridement, and morbidity and mortality. Having established the diagnosis of pancreatic necrosis, goals of appropriately aggressive resuscitation should be established and adhered to in a multidisciplinary approach, ideally at a high-volume pancreatic center. The role of antibiotics is determined by the presence of infected necrosis. Early enteral feeds improve outcomes compared with parenteral nutrition. Pancreatic necrosis is associated with a multitude of complications which can lead to long-term morbidity or mortality. Interventional therapy should be guided by available resources and the principle of a minimally invasive approach. When open debridement is necessary, it should be delayed at least 3-6 weeks to allow demarcation of necrotic from viable tissue

    Pancreatic acinar cells of adult mice (≥P60) are resistant to transformation by some of the most robust oncogenic insults including expression of K-Ras oncogenes and loss of p16Ink4a/p19Arf or Trp53 tumor suppressors. Yet, these acinar cells yield pancreatic intraepithelial neoplasias (mPanIN) and ductal adenocarcinomas (mPDAC) if exposed to limited bouts of non-acute pancreatitis, providing they harbor K-Ras oncogenes. Pancreatitis contributes to tumor progression by abrogating the senescence barrier characteristic of low-grade mPanINs. Attenuation of pancreatitis-induced inflammation also accelerates tissue repair and thwarts mPanIN expansion. Patients with chronic pancreatitis display senescent PanINs, if they have received anti-inflammatory drugs. These results put forward the concept that anti-inflammatory treatment of people diagnosed with pancreatitis may reduce their risk of developing PDAC. PMID:21665147

    Full Text Available When hyperechoic pancreatic parenchyma is observed on endoscopic or transabdominal ultrasound, fat infiltration of the pancreas is suspected. This condition was first reported by Ogilvie in 1993 and is termed fatty pancreas, pancreatic lipomatosis, non-alcoholic fatty pancreas, or pancreatic steatosis. Diagnosis of this condition mostly relies on imaging tools such as magnetic resonance imaging, computed tomography, or ultrasonography rather than histology. Although the condition is rare, it has clinical significance. There are multiple hypotheses regarded the etiology of this condition, listing factors such as viral infections, toxins, and congenital syndromes as possible causes. Metabolic syndrome and diabetes mellitus correlated with this condition. However, other etiologies should also be considered to aid specific treatment. In addition to a correlation between pancreatic steatosis and metabolic syndrome, relationships between pancreatic steatosis and worsened severity and prognosis of pancreatic cancer, increased complications after pancreatic surgery, and acute pancreatitis were reported. Gastroenterologists should be well informed about this condition for better care of these patients.

    The natural history of pseudoaneurysms complicating pancreatitis is unknown. A patient with chronic pancreatitis is described in whom thrombosis of a splenic artery pseudoaneurysm occurred. Early diagnosis and radical treatment of a bleeding pseudoaneurysm are mandatory. When elective treatment is considered, however, contrast enhanced computed tomography may be useful just before surgery as thrombosis may occur.

    Full Text Available Abstract Chronic pancreatitis is defined as a continuous or recurrent inflammatory disease of the pancreas characterized by progressive and irreversible morphological changes. It typically causes pain and permanent impairment of pancreatic function. In chronic pancreatitis areas of focal necrosis are followed by perilobular and intralobular fibrosis of the parenchyma, by stone formation in the pancreatic duct, calcifications in the parenchyma as well as the formation of pseudocysts. Late in the course of the disease a progressive loss of endocrine and exocrine function occurs. Despite advances in understanding the pathogenesis no causal treatment for chronic pancreatitis is presently available. Thus, there is a need for well characterized animal models for further investigations that allow translation to the human situation. This review summarizes existing experimental models and distinguishes them according to the type of pathological stimulus used for induction of pancreatitis. There is a special focus on pancreatic duct ligation, repetitive overstimulation with caerulein and chronic alcohol feeding. Secondly, attention is drawn to genetic models that have recently been generated and which mimic features of chronic pancreatitis in man. Each technique will be supplemented with data on the pathophysiological background of the model and their limitations will be discussed.

    Amiodarone, a class m antiarrhythmic drug, is one of the most effective drugs used in the treatment of ventricular and paroxysmal supraventricular tachyarrhythmia. Adverse effects of amiodarone including pulmonary toxicity, hepatotoxicity, aggravation of arrhythmia, and thyroid diseases are well understood. A 66-year old woman with acute pancreatitis was admitted to our hospital with the complaint of epigastralgia radiating to both flanks for two months. Her symptoms and elevation of pancreatic enzymes did not respond to conventional medical treatment of pancreatitis for 18 d. No known causal factors for pancreatitis such as biliary tract stone, hypertriglyceridemia and alcohol consumption could be identified. Under the suspicion of amiodarone-induced acute pancreatitis, amiodarone was substituted by propafenone. Her symptoms soon alleviated and serum lipase level declined. Three months after hospital discharge, the abdominal pain did not recur. Amiodarone was approved to treat recurrent ventricular fibrillation or sustained ventricular tachyarrhythmia that has been resistant to other medications since 1986. Pancreatitis is a very rare adverse effect associated with the use of amiodarone, and only four cases of amiodarone-induced pancreatitis have been reported in literature. We report a patient who developed acute pancreatitis during amiodarone therapy.

    Full Text Available Context There is only one previously published case report of acute pancreatitis secondary to the use of tetrahydrocannabinoid. While drugs, in general, account for 2% of all the causes of acute pancreatitis, we add to the literature three additional cases of cannabis-induced pancreatitis. Cases The first case occurred in a 22-year-old man who admitted to smoking tetrahydrocannabinoid heavily over the days prior to admission. The second case involved a 23-year-old man with multiple admissions for tetrahydrocannabinoid-induced pancreatitis. The third case involved a 20-year-old female who admitted to smoking tetrahydrocannabinoid heavily over a period of two weeks prior to admission. In all cases, other causes of pancreatitis were ruled out. Furthermore, the symptoms associated with the acute pancreatitis subsided upon discontinuation of the drug. Conclusion Cannabis is the world’s most popular illicit drug with over 4% of the world’s population using it each year. Despite this, acute pancreatitis is a rarely reported adverse effect of cannabis use. This case series adds to the literature that cannabis does in fact cause pancreatitis and it may be dose related, although the exact mechanism remains unknown.
