    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.

    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

Mutations in the cationic trypsinogen gene, pancreatic secretory trypsin inhibitor, and the cystic fibrosis conductance regulator gene do not account for the chronic pancreatitis noted in most patients with idiopathic chronic pancreatitis. Small duct chronic pancreatitis can be best diagnosed with a hormone stimulation test. Endoscopic ultrasonography can detect abnormalities in both the parenchyma and ducts of the pancreas. The true value of endoscopic ultrasonography in diagnosing small duct chronic pancreatitis remains to be fully defined and is under active investigation. It is not clear whether endoscopic ultrasonography is more sensitive for early structural changes in patients with small duct disease or is over diagnosing chronic pancreatitis. Pancreatic enzyme supplementation with non-enteric formulation along with acid suppression (H2 blockers or proton pump inhibitors is an effective therapy for pain in patients with small duct chronic pancreatitis. The role of endoscopic ultrasonography-guided celiac plexus block should be limited to treating those patients with chronic pancreatitis whose pain has not responded to other modalities. Total pancreatectomy followed by autologous islet cell autotransplantation appears to be potential therapeutic approach but for now should be considered experimental.La patogenia de la pancreatitis crónica idiopática sigue siendo poco conocida, a pesar de las expectativas de atribuir el daño pancreático que sufren los pacientes con esta enfermedad a factores genéticos.

  12. Folate Deficiency in Chronic Pancreatitis

    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

    2013-01-01

    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.

    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.

    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.

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.

    Full Text Available There is no universally accepted standard approach to treat patients with pancreatic cancer in the adjuvant setting. This controversy derives from several studies, each fraught with its own limitations. Standards of care also vary depending on which side of the Atlantic you are on: chemo-radiotherapy followed by chemotherapy is considered the optimal therapy in North America (GITSG, RTOG while chemotherapy alone is the current standard in Europe (ESPAC-1, CONKO. Whether gemcitabine is superior to 5-FU remains to be learnt from the ESPAC-3 study currently on-going in Europe. A number of important questions have yet to be fully addressed: • What is the absolute value of radiotherapy in this setting? • How should radiotherapy be delivered, if at all? • What should be the time to deliver of either or both therapeutic modalities in the adjuvant setting? • Are there any patients who can benefit from the combined modality? • What is the most appropriate chemotherapeutic agent(s to administer in the adjuvant setting? • Is there any role of integrating the novel/targeted agents, albeit the negative studies in the metastatic setting? • What are the new developments (such as vaccines, pancreas cancer stem cells, etc. in this area?

    2013-08-01

    Full Text Available The objective of this review is to analyze the actual scientific controversy on chronic cerebrospinal venous insufficiency (CCSVI and its association with both neurodegenerative disorders and multiple sclerosis (MS. We revised all published studies on prevalence of CCSVI in MS patients, including ultrasound and catheter venography series. Furthermore, we take into consideration other publications dealing with the pathophysiologic consequences of CCSVI in the brain, as well as ecent data characterizing the pathology of the venous wall in course of CCSVI. Finally, safety and pilot data on effectiveness of endovascular CCSVI treatment were further updated. Studies of prevalence show a big variability in prevalence of CCSVI in MS patients assessed by established ultrasonographic criteria. This could be related to high operator dependency of ultrasound. However, 12 studies, by the means of more objective catheter venography, show a prevalence >90% of CCSVI in MS. Global hypo-hypoperfusion of the brain, and reduced cerebral spinal fluid dynamics in MS was shown to be related to CCSVI. Postmortem studies and histology corroborate the 2009 International Union of Phlebology (UIP Consensus decision to insert CCSVI among venous malformations. Finally, safety of balloon angioplasty of the extracranial veins was certainly demonstrated, while prospective data on the potential effectiveness of endovascular treatment of CCSVI support to increase the level of evidence by proceeding with a randomized control trial (RCT. Taking into account the current epidemiological data, including studies on catheter venography, the autoptic findings, and the relationship between CCSVI and both hypo-perfusion and cerebro-spinal fluid flow, we conclude that CCSVI can be definitively inserted among the medical entities. Research is still inconclusive in elucidating the CCSVI role in the pathogenesis of neurological disorders. The controversy between the vascular and the

  13. Computerized tomography in acute and chronic 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

Non-pancreatic causes of pain and local complications, chiefly pseudocysts and biliary obstruction should be excluded in all patients. All patients should be advised to abstain from alcohol and smoking and opiates should be used only to control severe exacerbations of pain. Although pancreatic enzyme replacement is reported to be useful in the management of pancreatic pain, it is of little or no benefit in patients with established chronic pancreatitis. Celiac plexus block using steroids may be helpful to tide patients over an episode of severe pain. Intractable pain is an indication for surgery that includes pancreatic drainage procedure or pancreatic resection. For control of malabsorption, adequate pancreatic enzyme replacement with or

    textabstractIn exocrine pancreatic insufficiency, the pancreas is unable to deliver a sufficient quantity of pancreatic enzymes to the small intestine to digest food. It may occur in several life threatening diseases, including chronic pancreatitis and pancreatic cancer. Due to this lack or absence of pancreatic enzymes, malabsorption of fat develops, which causes steatorrhea-related symptoms, weight loss, and malnutrition. To reduce morbidity and even mortality, patients should be treated wi...

    A modern pahtogenetic and etiological classification of pancreatic diseases is observed in the review and the questions of dietotherapy concerning the main forms of the disease are under consideration. There are numerous sources given from literature where the question is discussed on the fiber level, quantitative and qualitative structure of the fatty part of the ration in case of chronic pancreatitis. The majority of native and foreign authors consider it inexpedient to reduce fiber lover than 120 g per day, however there is a number of works where it is recommended to increase in the ration the quantity of carbohydrates up to 400 g, reducing some fiber at the same time. There has appeared a number of works for the recent years, where it is recommended to include mixes for enteral nutrition into the diets recommended both for acute and chronic course of the disease. Such diets are emphasized to be well bearable and high effective during the treatment of this disease. PMID:17313040

    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.

  20. Segmental pancreatic autotransplantation for chronic pancreatitis. A preliminary report

    International Nuclear Information System (INIS)

    A patient who underwent 95% pancreatectomy with autotransplantation of the body and tail of the gland to the femoral area for chronic pancreatitis is presented. The pain resolved, and the patient's blood glucose level remained within normal limits. High levels of insulin were found in the iliac vein on the transplanted side. Patency of the graft was demonstrated by technetium scan and arteriography and followed by a color-coded Doppler imaging system. Segmental pancreatic autotransplantation offers a method of relieving pain with preservation of endocrine function in selected patients with chronic pancreatitis

    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.

    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.

    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.

    2015-01-01

    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

    BACKGROUND: Acinar cell carcinoma (ACC) is a rare malignancy of the pancreas arising from acinar cells. Unlike ductal adenocarcinoma, this tumor rarely presents with pancreatitis. METHODS: We present a case of ACC associated with chronic calcifying pancreatitis, and a review of the literature focusing on diagnosis and management. RESULTS: A 43-year-old man was proposed for Wirsungo-jejunal derivation for chronic pancreatitis. Histopathological examination of the tissue extracted revealed an ACC. Duodenopancreatectomy was performed. Six months post-operatively, the patient developed hepatic metastasis and was treated with gemcitabine as palliative chemotherapy. CONCLUSIONS: The clinical presentation of ACC of the pancreas is not speciifc and the tumor can be under-diagnosed when associated with chronic pancreatitis. Data regarding course, treatment, and prognosis of this tumor are generally lacking.

    AIM: To elucidate the frequency and characteristics of pancreatic disorders in the course of chronic viral hepatitis. METHODS: We prospectively assessed the serum pancreatic enzyme levels and imaging findings in patients with chronic viral hepatitis and healthy control subjects. RESULTS: Serum amylase (t-Amy), salivary amylase (s-Amy), pancreatic amylase (p-Amy) and serum lipase levels were higher in hepatitis patients in comparison to control subjects. However, in asymptomatic viral carriers, only the serum t-Amy levels were higher than those of the controls. The levels of each enzyme rose with the progression of liver disease in patients with hepatitis B or C; whereas the levels of each enzyme within the same clinical stage of the disease did not differ between patients diagnosed with either hepatitis B or hepatitis C virus. Imaging findings demonstrated chronic pancreatitis in only 1 out of 202 patients (0.5%).CONCLUSION: Our data suggest that serum levels of pancreatic enzymes increase with the progression of liver disease in patients diagnosed with viral hepatitis. Pancreatic disease, asymptomatic in most cases, may represent an extrahepatic manifestation of chronic viral hepatitis.

    Full Text Available BACKGROUND Almost all patients presenting with chronic hyperamylasemia undergo an expensive, long, difficult and often repeated diagnostic workup even if this occurrence is not associated with symptoms or with known pancreatotoxic factors. This is in relationship with the poor knowledge that, beside hyperenzymemia secondary to pancreatic diseases and systemic illnesses, various non-pathological forms of chronic hyperamylasemia can occur in clinical practice. AIM OF THE STUDY This study was addressed to assess the clinical characteristics of patients presenting with chronic hyperamylasemia unrelated to pancreatic diseases (CHUPD. PATIENTS AND METHODS Data of all patients with CHUPD were retrospectively reviewed (June 1997-March 2007. Forty patients were included in the study; median follow- up was 33 months (range 3-84 months. CHUPD was secondary to: a chronic benign pancreatic hyperamylasemia, 16 patients (40%; b macroamylasemia, 15 patients (37.5%; c salivary hyperamylasemia, 9 patients (22.5%. Gilbert’s syndrome was present in 13 patients (32.5%; 8 with macroamylasemia and hyperdyslipidemia in 8 patients (20%; 5 with chronic benign pancreatic hyperamylasemia. Diagnostic exams (all in the normal range performed before our observation were: Ca19-9 serum level in 37/40 (92.5%, ultrasonography and computed tomography-scan in all patients, endoscopic retrograde cholangiopancreatography in 21/40 (52.5%, abdominal magnetic resonance in 14/40 (35%. Previous diagnosis in these asymptomatic subjects were: chronic pancreatitis in 26 cases (65%; recurrent pancreatitis in 10 cases (25%; the remaining 4 patients (10% were addressed without a specific diagnosis. CONCLUSIONS In clinical practice, the occurrence of an unexplained chronic hyperamylasemia very often allows to an unappropriate diagnostic workup due to the poor familiarity with CHUPD conditions.

    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

    Chronic pancreatitis is a progressive inflammatory condition characterized by repeated attacks of abdominal pain, and the destruction and fibrosis of the pancreatic parenchyma which causes to reduced exocrine and endocrine functions. Alcohol is the most common cause of chronic pancreatitis. Although abstinence is usually considered a prerequisite for successful treatment of alcoholic chronic pancreatitis, we often encounter patients who have repeated attacks from the compensated stage through the transitional stage. In alcoholic chronic pancreatitis, continued alcohol consumption causes changes in the digestive hormones and vagal nerve function that induce the pancreatic acinar cells to oversecrete protein, increasing the protein concentration and viscosity of the pancreatic juice. This induces protein sedimentation from the pancreatic juice and formation of protein plugs within the pancreatic duct, triggering repeated attacks of acute pancreatitis. The treatment of alcoholic chronic pancreatitis includes alleviation of symptoms, particularly abdominal pain, elimination of trigger factors, prevention of recurrence and disease progression, adjuvant therapies for pancreatic exocrine and endocrine failure. Recently, the main constituent proteins in these protein plugs have been identified, enabling trials of several therapies, such as the administration of secretin formulations and endoscopic removal. Bromhexine hydrochloride, a bronchial mucolytic, has an affinity for the pancreatic acinar cells, inducing them to secrete pancreatic juice of low viscosity. In this review, we summarize the most recent thoughts about alcoholic chronic pancreatitis, and the new treatments, and in particular, we present our findings concerning the efficacy of bromhexine hydrochloride in the treatment of this disease.

    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

    Endoscopic therapy in chronic pancreatitis (CP) aims to provide pain relief and to treat local complications, by using the decompression of the pancreatic duct and the drainage of pseudocysts and biliary strictures, respectively. This is the reason for using it as first-line therapy for painful uncomplicated CP. The clinical response has to be evaluated at 6-8 weeks, when surgery may be chosen. This article reviews the main possibilities of endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound (EUS) therapies. Endotherapy for pancreatic ductal stones uses ultrasound wave lithotripsy and sometimes additional stone extractions. The treatment of pancreatic duct strictures consists of a single large stenting for 1 year. If the stricture persists, simultaneous multiple stents are applied. In case of unsuccessful ERCP, the EUS-guided drainage of the main pancreatic duct (MPD) or a rendezvous technique can solve the ductal strictures. EUS-guided celiac plexus block has limited efficiency in CP. The drainage of symptomatic or complicated pancreatic pseudocysts can be performed transpapillarily or transgastrically/transduodenally, preferably by EUS guidance. When the biliary stricture is symptomatic or progressive, multiple plastic stents are indicated. In conclusion, as in many fields of symptomatic treatment, endoscopy remains the first choice, either by using ERCP or EUS-guided procedures, after consideration of a multidisciplinary team with endoscopists, surgeons, and radiologists. However, what is crucial is establishing the right timing for surgery. PMID:25565876

The drainage of symptomatic or complicated pancreatic pseudocysts can be performed transpapillarily or transgastrically/transduodenally, preferably by EUS guidance. When the biliary stricture is symptomatic or progressive, multiple plastic stents are indicated. In conclusion, as in many fields of symptomatic treatment, endoscopy remains the first choice, either by using ERCP or EUS-guided procedures, after consideration of a multidisciplinary team with endoscopists, surgeons, and radiologists. However, what is crucial is establishing the right timing for surgery. Keywords: chronic pancreatitis, treatment, endoscopy, ERCP, endoscopic ultrasound

    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.

    In the past, chronic pancreatitis has been regarded as a fairly uniform and largely untreatable disorder that most commonly affects patients who both lack gainful employment or adequate insurance coverage and have a tendency to smoke and drink. Large clinical trials suggest that this perception is not only misguided and discriminatory but also not based on facts. We forgot that the perception of chronic liver disease was similar before World War II, and just like liver cirrhosis the fibrosis and cirrhosis of the pancreas--i.e. chronic pancreatitis--is the end result of a range of environmental, inflammatory, infectious and genetic disorders. A growing number of these have only recently been recognized as a distinct entity and several of which are becoming truly treatable. A large proportion of the risk for developing pancreatitis is conveyed by genetic risk factors, and we estimate that less than half of those have been identified so far. The same holds true for protective factors that can prevent pancreatitis, even in the face of excessive alcohol abuse. Various gene mutations and polymorphisms appear to determine an individual's susceptibility for developing pancreatic disease, for the severity of the disease, and for the disease progression. The spectrum of genotype/phenotype associations ranges from straightforward autosomal dominant traits with near-complete penetrance, as for the most common mutations in the cationic trypsinogen gene (PRSS1), to moderate risks factors without mendelian inheritance patterns, as for SPINK1 and CFTR mutations, to very subtle risk associations and disease modifiers that can only be identified in large cohort studies, as for the chymotrypsin C, calcium-sensing receptor and the anionic trypsin (PRSS2) mutations. Only a better understanding of the disease mechanisms that underlie these changes will make an individualized therapy of pancreatic disorders a realistic option. PMID:20814206

    The aim of this study was to assess the circadian variations of intragastric pH in 28 inpatients with chronic pancreatitis (mean (SD) age 46.8 (12.4) years) and in 14 controls (45.4 (9.8)). pH Metry was performed using a monocrystalline antimony electrode placed in the body of the stomach under fluoroscopic control and connected up to a recorder (MKII Digitrapper, Synectics). The evaluation parameters, expressed as median and interquartile range, were: total period, postprandial periods (P1 and P2), interdigestive, and nocturnal phases. Patients with chronic pancreatitis were subdivided into three groups on the basis of severity of exocrine pancreatic insufficiency (secretin-caerulein test: lipase output at 60-90 min)--that is, those with severe insufficiency (chronic pancreatitis-SI: 13 patients, lipase output < 10% normal values and pancreolauryl test < 20%), those with only mild insufficiency (chronic pancreatitis-MI: seven patients), and those with normal secretion (chronic pancreatitis-NF: eight patients). The chronic pancreatitis-SI patients present significantly greater gastric acidification in the postprandial periods compared with controls (P1: p < 0.001; P2: p < 0.01), and with chronic pancreatitis-MI plus chronic pancreatitis-NF subjects (P1: p < 0.01; P2: p < 0.05), taken together. In conclusion, gastric acidity, exocrine pancreatic insufficiency, and impaired digestion are closely related during the course of chronic pancreatitis. PMID:7883232

  8. Diagnostic value of computer tomography in chronic pancreatitis

    International Nuclear Information System (INIS)

    During a 3-year-period 39 patients with chronic pancreatitis were subjected to roentgen examinations and exocrine pancreatic function tests (EPFT). Computer tomography (CT) was carried out in 36 of these, and revealed pancreatic disease in 29, while characteristic findings of chronic pancreatitis were demonstrated in 24 patients. CT was particularly valuable in diagnosing intra- and extrapancreatic pseudocysts and pancreatic abscesses complicating chronic pancreatitis. At endoscopic retrograde pancreatography (ERP) pathologic alterations were demonstrated in 23 of 24 patients, and was diagnostic for chronic pancreatitis in 20 patients. The cannulation failed in 7 patients. The results indicate that ERP cannot be replaced by CT. ERP is still needed for detailed demonstration of the pancreatic duct system, especially preoperatively. Conventional films of the abdomen, EPFT and angiography were the least sensitive tests. (Auth.)

    Pancreatic head cancer is a common but the most lethal cancer of the human digestive system. It is invasive, resulting in early infiltration of adjacent structures and lymph node and distant metastases. Its biological characteristics of neurotropic growth lead to early neural invasion (NI) which is an independent prognostic factor of survival for pancreatic cancer. Radical surgical resection remains the only form of curative treatment. The extent of surgical resection and whether extended resection results in better long-term survival have been controversial. Studies have reported that peripancreatic plexus invasion is a frequent cause of pancreatic cancer recurrence and death. The relationship between cancer microenvironment and nerve cells, and whether the peripancreatic nerve plexus nearby needs to be resected require further studies. The present review aims to discuss the role of peripancreatic nerve and its implications in pancreatic head cancer resection. PMID:26458369

    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.

    Full Text Available CONTEXT: The clinical course of chronic pancreatitis in patients with mutations of cationic trypsinogen and the trypsin inhibitor SPINK1 has not yet been characterized. SETTING: Cationic trypsinogen (PRSS1 and the serine protease inhibitor, Kazal type 1 (SPINK1, were analyzed in patients with pancreatitis of unclear origin. PATIENTS: Eighty subjects with trypsinogen mutations (21x N29I, 59x R122H and 59 patients with the SPINK1 N34S variant (11 homozygous, 48 heterozygous were included in the study. MAIN OUTCOME MEASURES: In patients with mutations of PRSS1 (N29I, R122H and SPINK1 (N34S the parameters such as calcification, dilatation of the main pancreatic duct, diabetes mellitus, hospital treatments, and surgery were recorded. DESIGN: Case control studies were performed to compare both mutational groups, and the follow-up time served as a matching criterion. The Kaplan-Meier analysis was used to estimate the time course of the symptoms. RESULTS: Ten years after the onset of the disease, the probability (+/-SE of symptoms in patients with PRSS1 mutations was as follows: 1st hospital stay: 86+/-4%; calcification: 21+/-4%; duct dilatation: 26+/-9%; surgery: 19+/-5%; diabetes: 6+/-5%. After 25 years, we found the following data: 1st hospital stay: 96+/-3%; calcification: 38+/-8%; duct dilatation: 38+/-8%; surgery: 37+/-10%; diabetes: 28+/-8%. A case-control-study of 38 pairs of patients with either PRSS1 or SPINK1 mutations showed that the probability of duct dilatation, diabetes and calcification was slightly higher in patients having a SPINK1 mutation. There was no difference between those subjects with a homozygous or heterozygous SPINK1 mutation. In comparison to alcoholic chronic pancreatitis patients, the PRSS1 associated disease revealed a lower frequency of calcification and diabetes. CONCLUSIONS: The progression of chronic pancreatitis was slightly more rapid in patients with SPINK1 mutations than in patients with cationic trypsinogen

    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.

    Full Text Available Abstract Background A bleeding pseudoaneurysm in patients with chronic pancreatitis is a rare and potentially lethal complication. Optimal treatment of bleeding peripancreatic pseudoaneurysm remains controversial. This study reports on experience at Chang Gung Memorial Hospital (CGMH in managing of bleeding pseudoaneurysms associated with chronic pancreatitis. Methods The medical records of 9 patients (8 males and 1 female; age range, 28 – 71 years; median, 36 years with bleeding pseudoaneurysms associated with chronic pancreatitis treated at CGMH between Aug. 1992 and Sep. 2004 were retrospectively reviewed. Alcohol abuse (n = 7;78% was the predominant predisposing factor. Diagnoses of bleeding pseudoaneurysms were based on angiographic (7/7, computed tomographic (4/7, ultrasound (2/5, and surgical (2/2 findings. Whether surgery or angiographic embolization was performed was primarily based on patient clinical condition. Median follow-up was 38 months (range, 4 – 87 months. Results Abdominal computed tomography revealed bleeding pseudoaneurysms in 4 of 7 patients (57%. Angiography determined correct diagnosis in 7 patients (7/7, 100%. The splenic artery was involved in 5 cases, the pancreaticoduodenal artery in 2, the gastroduodenal artery in 1, and the middle colic artery in 1. Initial treatment was emergency (n = 4 or elective (n = 3 surgery in 7 patients and arterial embolization in 2. Rebleeding was detected after initial treatment in 3 patients. Overall, 5 arterial embolizations and 9 surgical interventions were performed; the respective rates of success of these treatments were 20% (1/5 and 89% (8/9. Five patients developed pseudocysts before treatment (n = 3 or following intervention (n = 2. Pseudocyst formation was identified in 2 of the 3 rebleeding patients.

Pathomorphological characteristics of the structural remodeling of the ductal apparatus of pancreas in patients with chronic pancreatitis, considering features of the ductal hypertension, proliferative and apoptotic activity of ductal epithelium. Methods. Complex pathomorphological study of pancreatic biopsies of 16 patients with severe pancreatic fibrosis at a chronic pancreatitis was performed. 10 patients had signs of pancreatic duct dilation, confirmed by ultrasound diagnostic, while in other patients ductal hypertension was not accompanied with the duct dilation. Immunohistochemical markers Ki-67 and Caspase-3 were used to detect proliferative and apoptotic activity, respectively. Results. 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.

    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.

    Full Text Available Context :Alcohol is the major aetiological agent for both chronic pancreatitis and alcoholic liver disease. However, as only a minority of alcoholics develop either chronic pancreatitis or alcoholic liver disease, there are clearly genetic or environmental cofactors that determine individual susceptibility to these diseases. Objective: To determine whether polymorphisms of the TNF gene may account for individual susceptibility to develop chronic pancreatitis or alcoholic liver disease. Design: A controlled study. Patients: We analyzed 73 patients with chronic pancreatitis, 103 healthy controls, 39 patients with alcoholic liver disease and 29 alcoholics without liver or pancreatic disease. Results: The intermediate/low TNF secreting haplotype a6b5c1d3e3 was over-represented in chronic pancreatitis compared to healthy controls (OR=2.08; 95% CI: 1.07-4.06; P=0.019 and in alcoholic chronic pancreatitis compared to healthy controls (OR=2.08; 95% CI: 1.01-4.29; P=0.029. The high TNF secreting haplotypes, a2b3c1d1e3 and a2b5c2d4e3 were under-represented in chronic pancreatitis compared to healthy controls (OR=0.48; 95% CI: 0.22-1.04; P= 0.043 and in alcoholic chronic pancreatitis compared to alcoholic controls (OR=0.20; 95% CI: 0.05-0.77; P=0.014, respectively. Conclusion :A reduced capacity to produce TNF may be responsible for the induction of chronic pancreatitis.

    Full Text Available Abstract Pancreatic neuroendocrine tumors are a rare entity with an incidence between 2 per million to 5 per 100 000. Association with pancreatitis (acute or chronic is rare and is considered to be determined by the tumoral obstruction of pancreatic ducts, but sometimes occurs without any apparent relationship between them. Non-functional neuroendocrine pancreatic tumors are usually diagnosed when either very large or metastatic. Small ones are occasionally diagnosed when imagery is performed for other diagnostic reasons. Intraoperative discovery is even rarer and poses problems of differential diagnosis with other pancreatic tumors. Association with chronic pancreatitis is rare and usually due to pancreatic duct obstruction by the tumor. We describe the case of a patient with a small non-functioning neuroendocrine tumor in the pancreatic tail accidentally discovered during surgery for delayed traumatic splenic rupture associated with chronic alcoholic pancreatitis. The tumor of 1.5cm size was well differentiated and confined to the pancreas, and was resected by a distal splenopancreatectomy. Conclusions Surgeons should be well aware of the rare possibility of a non-functional neuroendocrine tumor in the pancreas, associated with chronic pancreatitis, surgical resection being the optimal treatment for cure. Histopathology is of utmost importance to establish the correct diagnosis, grade of differentiation, malignancy and prognosis.

The possibility of an elevated concentration of plasma lactoferrin level in these patients needed to be explored even if the low pancreatic concentration of the protein did not favor this hypothesis. As expected, no increase could be observed between the plasma lactoferrin level of 16 patients with chronic calcifying pancreatitis (131 +/- 15 micrograms/l), compared to 17 controls (166 +/- 11 micrograms/l) and 15 patients with different organic diseases (187 +/- 18 micrograms/l).

    Full Text Available The etiology of chronic pancreatitis in Western countries is associated with chronic alcohol abuse in a high percentage of cases. In fact, we found that, in 190 Italian patients with proven chronic pancreatitis who were studied in the 2005, the etiology was alcohol abuse (more than 80 g/day for at least 5 years in 77.4% of the cases and due to other causes in 5.8% (hereditary pancreatitis in 2.6%, pancreatic malformation in 2.1%, cystic fibrosis transmembrane conductance regulator gene mutation in 0.5%, autoimmune pancreatitis in 0.5%; in 16.8% of the cases, a definite etiology of the pancreatitis was not recognized [1]. Although alcohol abuse is the main factor associated with chronic pancreatitis development, the pathological mechanisms involved in the initiation the disease remain obscure. One of the reasons for our difficulty in understanding the trigger mechanism between alcohol abuse and chronic pancreatic damage is the lack of animal and cellular models simulating the lesions such as those observed in humans. Gukovsky et al. [2] have recently found that rats which had been fed ethanol for 8 weeks, which had received cyclosporin A for the last two2 weeks and in which acute pancreatitis had been cerulein-induced had a massive loss of acinar cells, persistent inflammatory infiltration and fibrosis as compared to the control animals. Furthermore, macrophages in the treated rats were prominent in the inflammatory infiltrate and showed a marked increase in pancreatic NF-kappaB activation, cytokine/chemokine mRNA expression, collagen and fibronectin, in the expression and activities of matrix metalloproteinases 2 and 9 and in the activation of pancreatic stellate cells. Therefore, this study shows the possible mechanism by which alcohol sensitizes the pancreas to chronic injury.

    Full Text Available Context Dietary proteins and amino acids can modulate pancreatic function. Objective Our aim was to estimate the levels of plasma amino acids in chronic pancreatitis patients and study their relationship with disease characteristics as well as exocrine and endocrine insufficiency. Patients One hundred and seventy-five consecutive adult patients with chronic pancreatitis: 84 patients with alcoholic chronic pancreatitis and 91 patients with tropical chronic pancreatitis. One hundred and thirteen healthy controls were also studied. Design Prospective study. Main outcome measures Disease characteristics and imaging features were recorded. Plasma-free amino acid levels were estimated using reverse-phase high-performance liquid chromatography. Polyclonal antibody ELISA was used to assess pancreatic fecal elastase-1. Results The majority of the plasma free amino acid levels decreased in chronic pancreatitis patients whereas glutamate, glycine, proline and lysine were elevated as compared to the controls. Multivariate logistic regression analysis revealed that the decrease in branched chain amino acid concentration was significantly associated with the presence of diabetes and low fecal elastase-1. In addition, a significant positive correlation was observed between branched chain amino acids and pancreatic elastase-1 (rs=0.724, P

    In an era such as the present one in which there is a high demand for health services with the associated pressure of controlling spending, health care organizations are concerned about the cost-effectiveness of quality improvement interventions. On the other hand,the impact of the disease and the treatment on the patient's overall well-being and functioning has become a topic of growing interest not only in clinical research but also in practice. The clinical evaluation of the benefits of specific treatments for chronic, debilitating and incurable diseases should increasingly include formal assessment of patient activity and well-being. Thus, health-related quality of life as subjectively perceived by the patient,is becoming a major issue in the evaluation of any therapeutic intervention, mainly in patients with chronic or difficult diseases where the aim of the intervention is to keep patients either symptom-free and capable of living in the community for a long time or to reduce the discomfort caused by the disease. In this paper,we review the current knowledge on the quality of life assessment in chronic pancreatitis patients.

    Abstract The aim of this study is to explore whether there is a relationship between chronic pancreatitis and cerebrovascular disease in Taiwan. Using the claims data of the Taiwan National Health Insurance Program, we identified 16,672 subjects aged 20 to 84 years with a new diagnosis of chronic pancreatitis from 2000 to 2010 as the chronic pancreatitis group. We randomly selected 65,877 subjects aged 20 to 84 years without chronic pancreatitis as the nonchronic pancreatitis group. Both groups were matched by sex, age, comorbidities, and the index year of diagnosing chronic pancreatitis. The incidence of cerebrovascular disease at the end of 2011 was measured. The multivariable Cox proportional hazards regression model was used to measure the hazard ratio (HR) and 95% confidence interval (CI) for cerebrovascular disease risk associated with chronic pancreatitis and other comorbidities. The overall incidence of cerebrovascular disease was 1.24-fold greater in the chronic pancreatitis group than that in the nonchronic pancreatitis group (14.2 vs. 11.5 per 1000 person-years, 95% CI = 1.19–1.30). After controlling for confounding factors, the adjusted HR of cerebrovascular disease was 1.27 (95% CI = 1.19–1.36) for the chronic pancreatitis group as compared with the nonchronic pancreatitis group. Woman (adjusted HR = 1.41, 95% CI = 1.31–1.51), age (every 1 year, HR = 1.04, 95% CI = 1.04–1.05), atrial fibrillation (adjusted HR = 1.23, 95% CI = 1.02–1.48), chronic kidney disease (adjusted HR = 1.48, 95% CI = 1.31–1.67), chronic obstructive pulmonary disease (adjusted HR = 1.27, 95% CI = 1.16–1.40), diabetes mellitus (adjusted HR = 1.82, 95% CI = 1.72–1.92), hypertension (adjusted HR = 1.66, 95% CI = 1.56–1.76), and peripheral atherosclerosis (adjusted HR = 1.26, 95% CI = 1.06–1.51) were other factors significantly associated with cerebrovascular disease.

    To describe the CT and ERCP findings of mass-forming chronic pancreatitis. CT and ERCP features were assessed in 13 patients suffering from mass-forming chronic pancreatitis. Diagnosis was on the basis of surgery (n=5), percutaneous needle biopsy (n=3), and clinical follow-up (n=5). Contrast-enhanced CT was available for all patients : five underwent dynamic study and ERCP was performed in 12. On CT and ERCP, both groups were evaluated with regard to the presence and degree of pancreatic ductal dilatation (greater or less than 50 % of total gland width), double duct sign, enhancement pattern, pancreatic parenchymal calcification (site and distribution pattern), mass identification, the direction of infiltration, pancreatic parenchymal atrophy, configuration at the site of obstruction in the pancreatic and common bile duct, lymphadenopathy, vascular encasement, and vascular engorgement or increased collateral vessels in the peripancreatic space. Seven of 13 patients had suffered chronic alcoholism. Serum CA19-9 levels were normal in all patients except one. Common CT and ERCP findings of mass-forming chronic pancreatitis included pancreatic duct dilatation (92.3%), double duct sign (69.2%), inhomogeneous enhancement of the mass (69.2%), and the presence of calcification (61.5%). Patterns of pancreatic duct dilation were irregular in five patients (38.4%) and smooth in three (23.1%). In all patients, duct dilatation was less than 50% of total gland width. Enhancement patterns of the pancreatic mass were inhomogeneous (69.2%), a nonenhancing low attenuation mass (15.3%), and homogeneous enhancement (15.3%). Configuration at the site of obstruction in the pancreatic duct was abrupt termination in two patients (15.4%) and smooth termination in two (15.4%).

    Chronic pancreatitis is a progressive inflammatory disease of the pancreas and frequently associated with immoderate alcohol consumption. Since only a small proportion of alcoholics eventually develop chronic pancreatitis genetic susceptibility factors have long been suspected to contribute to the pathogenesis of the disease. Smaller studies in ethnically defined populations have found that not only polymorphism in proteins involved in the metabolism of ethanol, such as Alcohol Dehydrogenase and Aldehyde Dehydrogenase, can confer a risk for developing chronic pancreatitis but also mutations that had previously been reported in association with idiopathic pancreatitis, such as SPINK1 mutations. In a much broader approach employing genome wide search strategies the NAPS study found that polymorphisms in the Trypsin locus (PRSS1 rs10273639), and the Claudin 2 locus (CLDN2-RIPPLY1-MORC4 locus rs7057398 and rs12688220) confer an increased risk of developing alcohol-induced pancreatitis. These results from North America have now been confirmed by a European consortium. In another genome wide approach polymorphisms in the genes encoding Fucosyltransferase 2 (FUT2) non-secretor status and blood group B were not only found in association with higher serum lipase levels in healthy volunteers but also to more than double the risk for developing alcohol-associated chronic pancreatitis. These novel genetic associations will allow to investigate the pathophysiological and biochemical basis of alcohol-induced chronic pancreatitis on a cellular level and in much more detail than previously possible.

    AIM: To analyze the activation of sonic hedgehog (SHh) signaling pathways in a rat model of chronic pancreatitis. METHODS: Forty Wistar rats were randomly divided into 2 groups: experimental group and control group (20 rats in each group). Dibutyltin dichloride was infused into the tail vein of the rats to induce chronic pancreatitis in the experimental group. The same volume of ethanol and glycerol mixture was infused in the control group. The expression of Ptch, Smo and Gli were analyzed using immunohistochemistry, and real-time reverse transcription polymerase chain reaction (RT-PCR). RESULTS: Compared with the control group, significant histological changes in terms of the areas of abnormal architecture, glandular atrophy, fibrosis, pseudo tubular complexes, and edema were observed at week 4 in the experimental group. The expression of Ptch1, Smo and Gli1 in the pancreatic tissue increased significantly in the experimental group. Using RT-PCR, mRNA levels of Ptch, Smo and Gli in the experimental group increased significantly compared with the control group. CONCLUSION: The SHh signaling pathway is aberrantly activated in rats with chronic pancreatitis. The SHh signaling pathway plays an important role in the development of chronic pancreatitis. These results may be helpful in studies focusing on the relationship between chronic pancreatitis and pancreatic cancer. PMID:24782623

    Pancreaticopericardial fistula (PPF) is an extremely rare clinical problem encountered in patients with chronic pancreatitis. The diagnosis should be suspected if a patient presents with pericardial effusion on a background of chronic pancreatitis. Significantly raised amylase in the pericardial fluid offers an important clue for the diagnosis. CT is the initial imaging modality to look for pancreatic and pericardial changes. The therapeutic options include medical, endoscopic or surgical interventions. Medical and endoscopic therapies are the preferred modes of treatment while surgery is reserved for those who fail these measures. PMID:27190118

    Full Text Available Context: Chronic pancreatitis is an inflammatory condition that may result in progressive parenchymal damage and fibrosis which can ultimately lead to destruction of pancreatic tissue. Fistulas to the pleura, peritoneum, pericardium, and peripancreatic organs may form as a complications of pancreatitis. This case report describes an exceedingly rare complication, pancreaticoureteral fistula (PUF. Only two additional cases of PUF have been reported. However, they evolved following traumatic injury to the ureter or pancreatic duct. No published reports describe PUF as a complication of pancreatitis. Case Report: A 69-year-old Hispanic female with a past medical history of cholecystectomy, pancreatic pseudocyst, and recurrent episodes of pancreatitis presented with severe, sharp, and constant abdominal pain. Upon imaging, a fistulous tract was visualized between the left renal pelvis (at the level of an upper pole calyx and the pancreatic duct and a ureteral stent was placed to facilitate fistula closure. Following the procedure, the patient attained symptomatic relief and oral intake was resumed. A left retrograde pyelogram was repeated 2 months after the initial stent placement and demonstrating no evidence of a persistent fistulous tract. Conclusion: Due to PUF′s unclear etiology and possible variance of presentation, it is important for physicians to keep this rare complication of pancreatitis in mind, especially, when evaluating a patient with recurrent pancreatitis, urinary symptoms and abnormal imaging within the urinary collecting system and pancreas.

    Full Text Available Abstract Background The clinical course of chronic pancreatitis is still unpredictable, which relates to the lack of the availability of a clinical classification. Therefore, patient populations cannot be compared, the course and the outcome of the disease remain undetermined in the individual patient, and treatment is not standardized. Aim To establish a clinical classification for chronic pancreatitis which is user friendly, transparent, relevant, prognosis- as well as treatment-related and offers a frame for future disease evaluation. Methods Diagnostic requirements will include one clinical criterion, in combination with well defined imaging or functional abnormalities. Results A classification system consisting of three stages (A, B and C is presented, which fulfils the above-mentioned criteria. Clinical criteria are: pain, recurrent attacks of pancreatitis, complications of chronic pancreatitis (e.g. bile duct stenosis, steatorrhea, and diabetes mellitus. Imaging criteria consist of ductal or parenchymal changes observed by ultrasonography, ERCP, CT, MRI, and/or endosonography. Conclusion A new classification of chronic pancreatitis, based on combination of clinical signs, morphology and function, is presented. It is easy to handle and an instrument to study and to compare the natural course, the prognosis and treatment of patients with chronic pancreatitis.

    1989-01-01

    The goals of treatment with pancreatic extracts in patients with chronic relapsing pancreatitis are twofold: pain relief and control of maldigestion caused by exocrine pancreatic insufficiency. Experience with the use of pancreatic enzymes for analgesic purposes suggests that the less severe the pain, the greater the analgesic effect of these enzymes. However, the number of trials, as well as the number of patients treated, is fairly small and more studies in larger patient populations are needed. The use of pancreatic enzymes for maldigestion owing to exocrine pancreatic insufficiency which is secondary to chronic pancreatitis, pancreatectomy, cystic fibrosis, or GI bypass surgery incurs several problems. These problems are primarily caused by gastric inactivation of the enzymes, low enzyme activity of many commercial preparations and/or poor patient compliance. Treatment with conventional enzyme products (powdered extracts, enteric-coated tablets or capsules) has been disappointing. At best, results were inconsistent, showing a high degree of individual variation. The introduction of enzyme preparations in the form of pH-sensitive enteric-coated microspheres in hard gelatin capsules represents a significant advance. These microspheres are superior to conventional enzyme preparations in improving the symptoms of pancreatic insufficiency, particularly steatorrhea, where low doses of microspheres are as effective as large doses of conventional enzyme preparations. Steatorrhea, however, is rarely completely resolved. In cases refractory to therapy, treatment with the combination of pH-sensitive enteric-coated microspheres and H2-antagonists or prostaglandins has met with some success. PMID:2702247

    Full Text Available Synchronous major vessel resection during pancreaticoduodenectomy (PD for borderline resectable pancreatic adenocarcinoma remains controversial. In the 1970s, regional pancreatectomy advocated by Fortner was associated with unacceptably high morbidity and mortality rates, with no impact on long-term survival. With the establishment of a multidisciplinary approach, improvements in preoperative staging techniques, surgical expertise, and perioperative care reduced mortality rates and improved 5-year-survival rates are now achieved following resection in high-volume centres. Perioperative morbidity and mortality following PD with portal vein resection are comparable to standard PD, with reported 5-year-survival rates of up to 17%. Segmental resection and reconstruction of the common hepatic artery/proper hepatic artery (CHA/PHA can be performed to achieve an R0 resection in selected patients with limited involvement of the CHA/PHA at the origin of the gastroduodenal artery (GDA. PD with concomitant major vessel resection for borderline resectable tumours should be performed when a margin-negative resection is anticipated at high-volume centres with expertise in complex pancreatic surgery. Where an incomplete (R1 or R2 resection is likely neoadjuvant treatment with systemic chemotherapy followed by chemoradiation as part of a clinical trial should be offered to all patients.

    2009-01-01

    Exocrine pancreatic insufficiency caused by chronic pancreatitis results from various factors whichregulate digestion and absorption of nutrients. Pancreatic function has been extensively studied over the last 40 years, even if some aspects of secretion and gastrointestinal adaptation are not completely understood. The main clinical manifestations of exocrine pancreatic insufficiency are fat malabsorption, known as steatorrhea, which consists of fecal excretion of more than 6 g of fat per day, weightloss, abdominal discomfort and abdominal swelling sensation. Fat malabsorption also results in a deficit of fat-soluble vitamins (A, D, E and K) with consequent clinical manifestations. The relationships between pancreatic maldigestion, intestinal ecology and intestinal inflammation have not received particular attention, even if in clinical practice these mechanisms may be responsible for the low efficacy of pancreatic extracts in abolishing steatorrhea in some patients. The best treatments for pancreatic maldigestion should be re-evaluated, taking into account not only the correction of pancreatic insufficiency using pancreatic extracts and the best duodenal pH to permit optimal efficacy of these extracts, but we also need to consider other therapeutic approaches including the decontamination of intestinal lumen, supplementation of bile acids and, probably, the use of probiotics which may attenuate intestinal inflammation

    Chronic pancreatitis(CP) is a chronic inflammatory disease of the pancreas. The main symptom of patients with CP is chronic and severe abdominal pain. However, the pathophysiology of pain in CP remains obscure.Traditionally, researchers believed that the pain was caused by anatomical changes in pancreatic structure. However, treatment outcomes based on such beliefs are considered unsatisfactory. The emerging explanations of pain in CP are trending toward neurobiological theories. This article aims to review current evidence regarding the neuropathophysiology of pain in CP and its potential implications for the development of new treatments for pain in CP.

    The evidence from recent surveys on chronic pancreatitis carried out around the world shows that alcohol remains the main factor associated with chronic pancreatitis, even if at a frequency lower than that reported previously. It has further confirmed that heavy alcohol consumption and smoking are independent risk factors for chronic pancreatitis. Autoimmune pancreatitis accounts for 2%-4% of all forms of chronic pancreatitis, but this frequency will probably increase over the next few years. The rise in idiopathic chronic pancreatitis, especially in India, represents a black hole in recently published surveys. Despite the progress made so far regarding the possibility of establishing the hereditary forms of chronic pancreatitis and the recognition of autoimmune pancreatitis, it is possible that we are more inaccurate today than in the past in identifying the factors associated with chronic pancreatitis in our patients.

    Pharmacological, percutaneous celiac plexus blockade is often inefficient in the treatment of pain in chronic pancreatitis. Lack of efficiency could be due to incomplete denervation of the plexus; however, a method for measuring the completeness of celiac plexus blockade is not yet available. We...... block in 6 patients with chronic pancreatitis. Blood pressure decreased and heart rate increased after the block (P less than 0.025), whereas no significant change was found in hepato-splanchnic vascular resistance nor in the change of these parameters during transition from the supine to standing...... position. Pancreatic hormones (C-peptide, free insulin, glucagon, pancreatic polypeptide and somatostatin) did not change in response to standing, either before or after the block.

    Full Text Available Context The small intestine in chronic pancreatitis has not been investigated yet thoroughly. It would be important to understand fat metabolism in the course of this disease and could be explained if the small intestine has some pathological conditions and, due to this reason, pancreatic enzyme substitution does not work in all patients. Objective To investigate the pathophysiology of small intestine in chronic pancreatitis and to show the reason why in some cases pancreatic enzyme substitution does not work properly. Patients In the process of the study 33 chronic pancreatitis patients have been examined. Controls The control group includes 30 subjects without chronic pancreatitis similar for age, sex and alcohol consumption to the patients with chronic pancreatitis patients. Investigations Aspiration biopsy of jejunum mucosa followed by histological examination and investigation of intestinal enzymes by aspiration has been performed. Main outcome measures Metabolism at membranic level has been studied by enzymatic activity of amylase and lipase in the small intestine. Production of enzymes (monoglyceride lipase, lactase, saccharase, maltase, glycyl-lleucine dipeptidase promoting metabolism in enterocytes has been estimated as to their activity in homogenates of jejunum mucosasamples. Participation of mucosa in intestinal digestion has been assessed by alkaline phosphatase activity in a secretory chyme from proximal portion of jejunum. Absorptive capacity of jejunum was evaluated by D-xylose test results. DNA, lysozyme, immunoglobulin contents of chyme have also been calculated and bacteriological study of chyme has been also performed. Results Secondary enteritis, accompanied by moderate dystrophic changes of mucous membrane, thinning of limbus, and decrease of Paneth cell mitotic index, was found to occur in chronic pancreatitis patients. Enteritis is followed by changes in enzymatic processes in the sphere of membrane and intestinal

    2005-01-01

    Pancreatic cancer is a challenging disease for patients, doctors and researchers who for decades have searched for a cure for this deadly malignancy. Although existing mouse models of pancreatic cancer have shed light on the mechanistic basis of the neoplastic conversion of the pancreas, their impact in terms of offering new diagnostics and therapeutic modalities remains limited. Chronic pancreatitis is an inflammatory disease of the pancreas that is associated with a gradual damage of the organ and an increased risk of developing neoplastic lesions. In this review, we propose that detailed studies of chronic inflammatory processes in the pancreas will provide insights into the evolution of pancreatic cancer. This information may prove useful in the design of effective therapeutic strategies to battle the disease.

    Full Text Available ABSTRACT Objective: To compare the quality of life between patients with alcoholic chronic pancreatitis and controls, and between diabetic and non-diabetic patients, correlating clinical, sociodemographic, and nutritional factors with their quality of life scores. Methods: Forty-three outpatients of the pancreas and biliary tract clinic diagnosed with alcoholic chronic pancreatitis were assessed. Quality of life was measured by the Brazilian version of the Short Form-36. The control group consisted of 43 healthy companions. Nutritional status was classified according to body mass index and triceps, biceps, suprailiac, and subscapular skinfold thicknesses, using the appropriate methods. The percentage of body fat was given by adding the four skinfold thicknesses and by bioelectrical impedance analysis. The statistical tests included the Chi-square, Mann-Whitney, and Spearman's correlation tests, with the significance level set at p<0.05. Results: The sociodemographic variables of the case and control groups did not differ. Quality of life was lower in alcoholic chronic pancreatitis patients than in controls. The only quality of life domain that differed between diabetics and non-diabetics was functional capacity, lower in diabetics (p=0.022. Smoking duration, alcohol intake in grams, and time since pancreatic surgery correlated negatively with the quality of life of alcoholic chronic pancreatitis patients. Old age, skinfold thicknesses, and percentage of body fat correlated positively with quality of life. Conclusion: Quality of life is low in alcoholic chronic pancreatitis patients because of the negative influence of certain factors, such as smoking duration, amount of alcohol consumed, and time since pancreatic surgery.

    Full Text Available The relationship between pancreatic fibrosis and apoptosis of pancreatic acinar cells has not been fully elucidated. We reported that taurine had an anti-fibrotic effect in a dibutyltin dichloride (DBTC-chronic pancreatitis model. However, the effect of taurine on apoptosis of pancreatic acinar cells is still unclear. Therefore, we examined apoptosis in DBTC-chronic pancreatitis and in the AR42J pancreatic acinar cell line with/without taurine. Pancreatic fibrosis was induced by a single administration of DBTC. Rats were fed a taurine-containing diet or a normal diet and were sacrificed at day 5. The AR42J pancreatic acinar cell line was incubated with/without DBTC with taurine chloramines. Apoptosis was determined by using terminal deoxynucleotidyl transferase-mediated dUTP-digoxigenin nick end labeling (TUNEL assay. The expression of Bad and Bcl-2 proteins in the AR42J cells lysates was detected by Western blot analysis. The apoptotic index of pancreatic acinar cells in DBTC-administered rats was significantly increased. Taurine treatment inhibited pancreatic fibrosis and apoptosis of acinar cells induced by DBTC. The number of TUNEL-positive cells in the AR42J pancreatic acinar cell lines was significantly increased by the addition of DBTC. Incubation with taurine chloramines ameliorated these changes. In conclusion, taurine inhibits apoptosis of pancreatic acinar cells and pancreatitis in experimental chronic pancreatitis.

  10. The significance of pancreatic juice trace-element concentration in chronic pancreatitis

    International Nuclear Information System (INIS)

    The diagnosis of exocrine pancreas insufficiency in patients with chronic pancreatitis is still not easy. The best-suited method to confirm the diagnosis seems to be the secretin pancreozymin test (SPT). As previous results have shown, the determination of trace elements in the pancreatic juice can improve the diagnostic value of the SPT. During the SPT, the concentrations of Zn, Fe, Rb, Co, Cr, Se, Sb, Cs, Sc and Ag were measured in the duodenal aspirate of 50 patients by instrumental neutron activation analysis. Of the 50 patients, 24 suffered from pancreatic insufficiency in chronic pancreatitis and 26 had no signs of pancreatic insufficiency. Only the concentration of zinc differed significantly in the two groups; the other elements showed a similar behaviour. In patients without disease of the exocrine pancreas the zinc content of the pancreatic juice during the SPT ws 0.46+-0.13μg/ml, whereas in patients with pancreatic insufficiency it was only 0.18+-0.07μg/ml. The corresponding output was 171+-49.3μg zinc in controls and 41+-17.4μg in patients. After stimulation with pancreozymin the concentrations of zinc increased in normal patients to 1.13+-0.14μg/ml and to 0.22+-0.12μg/ml in patients with pancreatic insufficiency. The data demonstrate that the measurement of zinc in the duodenal juice during the SPT improves the diagnostic value of the test and that zinc should also be determined in doubtful cases of pancreatic insufficiency.

    To evaluate the major radiologic features of chronic focal pancreatitis in various imaging studies, with special emphasis on CT and ERCP findings. From 1991 to 1995, twelve patients were pathologically proved to be suffering from focal chronic pancreatitis after pancreatico-duodenectomy;for retrospective evaluation, imaging studies were available for eight(seven men, one woman;mean age 58.9±6.6, range 47 to 67). Clinical, surgical, and radiological findings, including CT(n=8), ultrasound(n=7), ERCP(n=8) and UGI(n=3) were analysed. Seven male patients had suffered from chronic alcoholism for between 20 and 50 years. Serum bilirubin levels were normal in eight patients and alkaline phosphatase levels were normal in seven patients. Serum CA 19-9 levels were normal in all five patients who had undergone preoperative evaluation. Seven patients(87.5%) showed focal enlargement without definable margin on CT, and five of the six lesions detectable on ultrasound(83.3%) were ill defined hypoechoic nodules. Dilated side branches within lesions were seen in five of eight patients(83.3%) on CT and ERCP. Double duct signs were observed in siven(87.5%) patients, and dilated intrahepatic ducts in six(75%), with diameters ranging from 5 to 8mm(average:5.42±1.96mm). The average ratio of pancreatic duct caliber to gland width was 0.33±0.19. None of the patients had calcification within the lesion and one case showed intraductal calcification. None showed perivascular fat obliteration around the superior mesenteric artery or celiac axis. The average biductal distance between abnormal common bile duct and the immediately adjacent pancreatic duct was 4.0±1.15mm.

    AIM: To investigate c-met expression during early pancreatic carcinogenesis.METHODS: We used 46 bulk tissues and 36 microdissected samples, including normal pancreas, chronic pancreatitis, and pancreatic cancer, for quantitative real time reverse transcription-polymerase chain reaction.RESULTS: In bulk tissue analyses, pancreatic cancer tissues expressed significantly higher levels of c-met than did chronic pancreatitis and normal pancreas tissues.c-met levels did not differ between chronic pancreatitis and normal pancreas tissues. In microdissection-based analyses, c-met was expressed at higher levels in microdissected pancreatic cancer cells and pancreatitisaffected epithelial cells than in normal ductal epithelial cells (both, P < 0.01). Interestingly, pancreatitis-affected epithelial cells expressed levels of c-met similar to those of pancreatic cancer cells.CONCLUSION: Overexpression of c-met occurs during the early stage of pancreatic carcinogenesis, and a single alteration of c-met expression is not sufficient for progression of chronic pancreatitis-affected epithelial cells to pancreatic cancer cells.

The use of porcine pancreatic enzymes for the correction of exocrine insufficiency is governed by the pathophysiology of the disease as well as pharmacologic properties of PES. Variability in bioequivalence of PES has been noted on in vitro and in vivo testing and has been attributed to the differences in enteric coating and the degree of micro-encapsulation. As a step towards standardizing pancreatic enzyme preparations, the Food and Drug Administration now requires the manufacturers of PES to obtain approval of marketed formulations by April 2010. In patients with treatment failure, apart from evaluating drug and dietary interactions and compliance, physicians should keep in mind that patients may benefit from switching to a different formulation. The choice of PES (enteric coated versus non-enteric coated and the need for acid suppression should be individualized. There is no current standard test for evaluating adequacy of therapy in CP patients and studies have shown that optimization of therapy based on symptoms may be inadequate. Goals of therapy based on overall patient presentation and specific laboratory tests rather than mere correction of steatorrhea are needed.Keywords: pancreatic exocrine insufficiency, chronic pancreatitis, pancreatic enzyme supplement

    Progress made in identifying the genetic susceptibility underlying acute and chronic pancreatitis has benefitted the clinicians in understanding the pathogenesis of the disease in a better way. The identification of mutations in cationic trypsinogen gene(PRSS1 gene; functional gain mutations) and serine protease inhibitor kazal type 1(SPINK1 gene; functional loss mutations) and other potential susceptibility factors in genes that play an important role in the pancreatic secretory functions or response to inflammation during pancreatic injury has changed the current concepts and understanding of a complex multifactorial disease like pancreatitis. An indi-vidual’s susceptibility to the disease is governed by ge-netic factors in combination with environmental factors. Candidate gene and genetic linkage studies have iden-tified polymorphisms in cationic trypsinogen(PRSS1), SPINK1, cystic fibrosis trans-membrane conductance regulator(CFTR), Chymotrypsinogen C(CTRC), Ca-thepsin B(CTSB) and calcium sensing receptor(CASR). Individuals with polymorphisms in the mentioned genes and other as yet identified genes are at an enhanced risk for the disease. Recently, polymorphisms in genes other than those involved in "intra-pancreatic trypsin regulatory mechanism" namely Claudin-2(CLDN2) andCarboxypeptidase A1(CPA1) gene have also been iden-tified for their association with pancreatitis. With ever growing number of studies trying to identify the genetic susceptibility in the form of single nucleotide polymor-phisms, this review is an attempt to compile the avail-able information on the topic.

    Chronic ethanol consumption is well established as a major risk factor for type-2 diabetes(T2D), which is evidenced by impaired glucose metabolism and insulin resistance. However, the relationships between alcoholconsumption and the development of T2 D remain controversial. In particular, the direct effects of ethanol consumption on proliferation of pancreatic β-cell and the exact mechanisms associated with ethanolmediated β-cell dysfunction and apoptosis remain elusive. Although alcoholism and alcohol consumption are prevalent and represent crucial public health problems worldwide, many people believe that low-tomoderate ethanol consumption may protect against T2 D and cardiovascular diseases. However, the J- or U-shaped curves obtained from cross-sectional and large prospective studies have not fully explained the relationship between alcohol consumption and T2 D. This review provides evidence for the harmful effects of chronic ethanol consumption on the progressive development of T2 D, particularly with respect to pancreatic β-cell mass and function in association with insulin synthesis and secretion. This review also discusses a conceptual framework for how ethanolproduced peroxynitrite contributes to pancreatic β-cell dysfunction and metabolic syndrome.

  20. Pancreaticoduodenectomy (Whipple resection) in the treatment of chronic pancreatitis.

    The armamentarium of the pancreatic surgeon must include multiple operative techniques, to be adapted to the clinical and anatomical findings in the patient with chronic pancreatitis. Pancreaticoduodenectomy is an essential component of this armamentarium. Its indications and limitations require continued refinement. Pancreaticoduodenectomy (Whipple operation) provides excellent results in the relief of the pain of chronic pancreatitis. The incidence of reoperation for control of pain after this procedure is less than after drainage procedures. The postoperative mortality rate in recent report is less than 2%. Whereas resection of pancreatic tissue diminishes pancreatic function, the metabolic deficits are partially compensated by the better nutritional status resulting from pain relief and discontinuation of narcotics. In experienced hands, pancreaticoduodenectomy would appear to be the procedure of choice in patients with small pancreatic ducts. In selected patients, it appears to be a good procedure and, possibly, the operation of choice when the disease is predominantly present in the head of the pancreas and/or the uncinate process, especially when strictures involve the common bile duct and duodenum. The authors prefer the procedure when a hard, chronically-inflamed mass is present in the head of the pancreas. In our experience, if the suspicion of malignancy of the head of the pancreas persists at operation, pancreaticoduodenectomy is the procedure of choice. Before undertaking resection, the individual surgeon must assess his/her own experience; a low risk is essential. The continuing alcoholic is not a candidate for pancreaticoduodenectomy. Those who will not stop drinking should seldom be accepted for resection. The same limitation exists for the narcotic addict, but few such patients are encountered today. In the authors' experience, the operation is excellent for the relief of pain. It is the lifestyle of the continuing alcoholic that poses the more

  1. Differential diagnosis between pancreatic ductal adenocarcinoma from chronic pancreatitis with thin slice table incremental CE-CT

    International Nuclear Information System (INIS)

    Thin slice table incremental CE-CT was performed in 18 patients with suspected pancreatic carcinoma, 13 patients with chronic pancreatitis, and 19 patients with normal pancreas. First, sequential pre-contrast CT (plain) scanning was undertaken at 10 mm intervals. Second, a bolus of 50-60 ml of 300 mgI/ml iopamidol was delivered intravenously via a peripheral arm vein, and subsequent drip injections were administered to end up with a total of 100 ml of the iopamidol, and sequential scans were obtained at 5 mm intervals. Third, delayed scanning was performed 1-2 minutes later. Average CT numbers for pancreatic carcinoma, chronic pancreatitis, and normal pancreas were calculated on plain CT, CE-CT, and delayed CT. For pancreatic carcinoma, average CT numbers were 41.6 HU±6.4 HU, 69.6 HU±10.4 HU, and 86.2 HU±14.7 HU on plain CT, CE-CT, and delayed CT, respectively. The corresponding figures by plain CT, CE-CT, and delayed CT were 50.0 HU±5.0 HU, 94.3 HU±13.3 HU, and 82.5 HU±11.6 HU for chronic pancreatitis; and 51.3 HU±5.7 HU, 93.5 HU±7.6 HU, and 82.0 HU±11.6 HU for normal pancreas, respectively. CT numbers on plain CT and CE-CT were sigificantly lower in the group of pancreatic carcinoma than the other groups of chronic pancreatitis and normal pancreas. However, there was no significant difference in CT numbers on delayed CT among the groups. For chronic pancreatitis and normal pancreas, CT numbers were similar on any of the three phase CT scans. EC-CT may be useful in differentiating pancreatic carcinoma from chronic pancreatitis, although it may be of limited value in differentiating chronic pancreatitis and normal pancreas. (N.K.)

    Full Text Available Context Insertion of a self-expandable metal stent is still controversial for treatment of benign common bile duct stenosis but can be a valuable alternative to surgical treatment. Objective Aim of our study was to analyze the efficacy of covered and uncovered selfexpandable metal stent in patients with chronic pancreatitis and common bile duct stenosis. Material and methods Twenty patients with common bile duct stenosis due to alcoholic chronic pancreatitis were retrospective analyzed. All patients had advanced chronic pancreatitis, presenting with calcifications in pancreatic head. Uncovered self-expandable metal stent (uSEMS were used in 11 patients (3 females, 8 males while in 9 patients (3 females, 6 males partially covered self-expandable metal stent (cSEMS were inserted. All patients treated with self-expandable metal stent had contraindications for surgery. Results Overall mean follow up time was 155 weeks: 206 (52-412 weeks in uSEMS, and 93 (25-233 weeks in cSEMS, respectively. Stent patency was in mean 118 weeks: 159 (44-412 weeks in uSEMS and 67 (25-150 weeks in cSEMS (P=0.019. In the uSEMS group, reintervention was necessary in 5 patients (45% due to stent obstruction, whereas in the cSEMS group 4 patients (44% needed reintervention (2 obstructions, 2 migration. Stent migration is an early complication, compared to obstruction (P<0.05, and in cSEMS obstruction occurred significantly earlier compared to uSEMS (P<0.05. Conclusion Patency of uSEMS was significantly longer compared to partially cSEMS. Available self-expandable metal stent, unfortunately, do not meet the demands on successful treatment of benign common bile duct stenosis.

    Breider, M A; Kiely, R G; Edwards, J F

    1985-04-15

    A generalized debilitating disease in a horse was believed to be related to hypersensitivity to migrating strongyle larvae. The clinical signs included weight loss, diarrhea, and ulcers on all 4 coronary bands. The mare's condition deteriorated rapidly, so the mare was euthanatized and necropsied. The major histopathologic findings were chronic multifocal eosinophilic pancreatitis, hepatic portal fibrosis, biliary hyperplasia, and chronic ulcerative eosinophilic colitis. This case was similar to previously reported cases of chronic eosinophilic gastroenteritis in horses. Although the etiologic agent was not evident, the distribution and character of the lesions were consistent with a hypersensitivity response to migrating parasitic larvae, most probably Strongylus equinus.

  12. Radiological evaluation about the effects of acute and chronic pancreatitis on the stomach patterns

    International Nuclear Information System (INIS)

    The present study was intended to examine the spectrum of radiographic patterns of the stomach associated with acute and chronic pancreatitis and their complications. Subjects served for the study consisted of 70 cases of pancreatitis (36 cases in acute stage and 34 cases in chronic stage). Intramural and perigastric permeation of extravasated pancreatic enzymes and secondary inflammatory reaction that follows are responsible for the radiographic change observed. 1. Generalized rugal thickening and particularly selective mucosal prominences in greater curvature of body and antrum are characteristically seen in acute (14 of 36 cases- 39%) and chronic pancreatitis (11 of 34 cases- 32%) 2. The only finding of the chronic pancreatitis includes patterns mimicking limits plastica, indurated and nondistensible rugae induced by perigastric adhesion (11 of 34 cases- 32%) Familiarization with these patterns of involvement contributes to the radiographic diagnosis of acute pancreatitis and avoides serious diagnostic errors in case of chronic pancreatitis

  13. 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.

    2010-08-01

    Chronic pancreatitis results in exocrine and endocrine dysfunction, affecting normal digestion and absorption of nutrients. In individuals with chronic pancreatitis, nutrition status may be further affected by poor dietary intake, often related to alcoholism. However, some deficiencies may be overlooked, potentially leading to nutrition-related problems with bone health and fatigue. The aim of this article is to describe the deficiencies that occur and to propose an evidence-based algorithm for the nutrition assessment and treatment of patients with chronic pancreatitis.

    Full Text Available Introduction Pancreatic exocrine insufficiency is associated with various pancreatic illnesses and could be associated with extra pancreatic diseases. In chronic heart failure patients, the splanchnic circulation is decreased. If the reduced circulation is prolonged, tissue damage to the splanchnic organs is possible. The aim of our study was to determine the prevalence of pancreatic exocrine insufficiency in chronic heart failure patients as well as its clinical importance. Patients and Methods Patients with known chronic heart failure were selected from the outpatient cardiology clinic, and chronic heart failure was classified according to the New York Health Association criteria. Pancreatic exocrine insufficiency was diagnosed by the faecal elastase-1 concentration. Levels of >200 μg/g, 100-200 μg/g and <100 μg/g were considered as normal exocrine pancreatic function, mild pancreatic exocrine insufficiency and severe pancreatic exocrine insufficiency, respectively. In patients with low FE, additional serum laboratory testing was performed. Results In total, 87 patients were included in the study, and 56 (64.4% were male and 31 (35.6% were female; the mean age was 74.7±8.9 years (range 48-90.There were 54 patients with NYHA II and 33 patients with NYHA III chronic heart failure. The mean time from the confirmation of chronic heart failure to inclusion in the study was 4.0±3.3 years. Pancreatic exocrine insufficiency was diagnosed in six (6.9% patients as follows: severe pancreatic exocrine insufficiency was diagnosed in three (3.45% patients, and mild pancreatic exocrine insufficiency in three (3.45% patients. In all of the tested pancreatic exocrine insufficiency patients, nutritional serum markers were decreased (vitamin D, selenium, phosphorus, zinc, folic acid and prealbumin. Conclusions Pancreatic exocrine insufficiency could develop in a low percentage of chronic heart failure patients. Decreased values of serum nutritional markers

    Full Text Available Context There are classical radiological features for the diagnosis of chronic pancreatitis when utilising endoscopic retrograde cholangiopancreatography (ERCP, magnetic resonance cholangiopancreatography (MRCP or computed tomography (CT, however, not all patients exhibit these features despite convincing clinical histories, which may result in diagnostic delay. Objective The aim of this study was to assess the use of endoscopic ultrasound (EUS in the diagnosis of chronic pancreatitis when other imaging modalities had not yielded a diagnosis. Methods All patients undergoing pancreatic EUS between January 1996 and December 2004 were identified from the radiology computerised database. Sixteen patients with a clinical diagnosis of chronic pancreatitis (10 males, 6 females; mean age 53±4 years underwent EUS after normal conventional imaging. Patients were then followed clinically until December 2007. Results Thirteen patients exhibited features of chronic pancreatitis not identified by other modalities, which included duct dilatation (n=8, calcification (n=7; parenchymal change (n=6, irregular undilated ducts (n=2, pancreatic ductal calculi (n=1, and fine calcification (n=1. Of the remaining 3 patients, a diagnosis of autoimmune pancreatitis was made in one, in another there was a pancreatic duct stricture of uncertain origin that was stented, and in only one case was no diagnosis established. All 13 patients with an EUS diagnosis of chronic pancreatitis subsequently underwent a repeat CT scan for surveillance of their disease and in all cases, the CT scans subsequently demonstrated evidence of chronic pancreatitis indicating radiological progression. No new pancreaticobiliary diagnoses were established during this period. Conclusions EUS is a useful diagnostic tool confirming the diagnosis of chronic pancreatitis in 13 of 16 cases where histories were suspicious of chronic pancreatitis, and providing an alternative diagnosis in another two cases

  20. Pancreatic Extracts for Painful Chronic Pancreatitis: Micronutrient Antioxidant Therapy by Proxy

    Directory of Open Access Journals (Sweden)

    Joan M Braganza

    2014-11-01

    Full Text Available Pancreatic extracts have found their way into clinical practice to treat painful chronic pancreatitis, despite consensus from analysis of randomized controlled trials (RCT that there is no clear evidence of benefit [1-3]. Proponents argue that success depends upon the use of non-enteric coated material to ensure delivery of proteases into the duodenum as in two RCT [4, 5], compared to several unsuccessful RCT using enteric coated preparations that deliver the enzymes further downstream [1-3]. It is posited that intraduodenal delivery ‘puts the pancreas to rest’ by dampening the feedback loop that otherwise leads, via high circulating levels of cholecystokinin - pancreozymin (CCK, to pain from pancreatic ductal hypertension. Clinicians are informed that patients with small-duct disease and mild to moderately impaired pancreatic secretory capacity will benefit, whereas those with advanced disease / steatorrhea will not. A proton pump inhibitor is advised, to safeguard the extracts in transit through the stomach. Treatment is advocated for four weeks in the first instance, to be continued for six months in responders, and indefinitely should pain resurface upon attempted withdrawal of treatment [6].

    2003-01-01

    AIM: To identify the expression of Caspase-l(interleukin1.β converting enzyme) and its role in adenoma of the pancreas and chronic pancreatitis.METHODS: The expression of Caspase-1 was assessed in 42 pancreatic cancer tissue samples, 38 chronic pancreatitis specimens, and 9 normal pancreatic tissues by immunohistochemistry and Western blot analysis.RESULTS: Overexpression of Caspase-1 was observed in both disorders, but there were differences in the expression patterns in distinct morphologic compartments. Pancreatic cancer tissues showed a clear cytoplasmatic overexpression of Caspase-1 in tumor cells of 71% of the tumors, whereas normal pancreatic tissues showed only occasional immunoreactivity. In chronic pancreatitis, overexpression of Caspase-1 was found in atrophic acinar cells (89 %),hyperplastic ducts (87 %), and dedifferentiating acinar cells (84 %). Although in atrophic cells a clear nuclear expression was found, hyperplastic ducts and dedifferentiating acinar cells showed dear cytoplasmic expression. Western blot analysis revealed a marked expression of the 45 kDa precursor of Caspase-1 in pancreatic cancer and chronic pancreatitis (80 %and 86 %, respectively). Clear bands at 30 kDa, which suggested the p10-p20 heterodimer of active Caspase-1, were found in 60 % of the cancer tissue and 14 % of the pancreatitis tissue specimens, but not in normal pancreatic tissues.CONCLUSION: Overexpression of Caspase-1 is a frequent event in pancreatic disorders and its differential expression patterns may reflect two functions of the protease. One is its participation in the apoptotic pathway in atrophic acinar cells and tumor-surrounding pancreatitis tissue, the other is its possible role in proliferative processes in pancreatic cancer cells and hyperplastic duct cells and dedifferentiating acinar cells in chronic pancreatitis.

  3. Diagnosis of Early Chronic Pancreatitis by Endoscopic Ultrasound. Are We There Yet?

    Directory of Open Access Journals (Sweden)

    2004-01-01

    Full Text Available The diagnosis of chronic pancreatitis at an early stage is a clinical challenge. A major limitation is the inability of clinicians to obtain a tissue or histological sample to confirm the clinical diagnosis. Currently available imaging modalities have limited sensitivity or specificity for diagnosing early chronic pancreatitis. Endoscopic ultrasonography (EUS, introduced in the early 1980's, was first developed to image the pancreas. It overcame many of the limitations (abdominal gas and fat of transabdominal ultrasonography when evaluating patients for possible pancreatic diseases. To date, EUS represents the most promising imaging modality for diagnosing chronic pancreatitis. Contrary to endoscopic retrograde pancreatography (ERCP, EUS has a very low risk of complications and can detect abnormalities suggestive of chronic pancreatitis in the pancreatic parenchyma and ductal system which are not visible on any other imaging modality. The minimal changes in echotexture are difficult to interpret because there is no reliable gold standard confirmatory test. There is now some evidence in the literature suggesting that these early changes detected by EUS correlate with the histological changes of chronic pancreatitis and may predict progression to more advanced disease. The EUS diagnosis of chronic pancreatitis relies on quantitative (more than qualitative parenchymal and ductal criteria found during evaluation of the pancreas. It is generally accepted that, in the absence of any criteria, chronic pancreatitis is unlikely, whereas in the presence of 5 or more criteria (out of 9-11 chronic pancreatitis is likely although ERCP and pancreatic function tests may still be normal. The diagnostic significance of patients with fewer (1-4 criteria found on EUS is currently unclear, particularly when other diagnostic tests such as ERCP and function testing are normal. In these cases, there is a potential for "over-diagnosis" of chronic pancreatitis, since

    AIM: To summarize progress in the study of K-ras gene studies in pancreatic cancer and its potential clinical significance in screening test for early detection of pancreatic cancer, and to differentiate pancreatic cancer from chronic pancreatitis in recent decade.METHODS: Literature search (MEDLINE 1986-2003) was performed using the key words K-ras gene, pancreatic cancer, chronic pancreatitis, and diagnosis. Two kind of opposite points of view on the significance of K-ras gene in detection early pancreatic cancer and differentiation pancreatic cancer from chronic pancreatitis were investigated.The presence of a K-ras gene mutation at codon 12 has been seen in 75-100% of pancreatic cancers, and is not rare in patients with chronic pancreatitis, and represents an increased risk of developing pancreatic cancer. However, the significance of the detection of this mutation in specimens obtained by needle aspiration from pure pancreatic juice and from stools for its utilization for the detection of early pancreatic cancer, and differentiation pancreatic cancer from chronic pancreatitis remains controversial. CONCLUSION: The value of K-ras gene mutation for the detection of early pancreatic cancer and differentiation pancreatic cancer from chronic pancreatitis remains uncertains in clinical pratice. Nevertheless, K-ras mutation screening may increase the sensitivity of FNA and ERP cytology and may be useful in identifying pancreatitis patients at high risk for developing cancer, and as a adjunct with cytology to differentiate pancreatic cancer from chronic pancreatitis.

    Background: Mass-forming chronic pancreatitis may mimic a pancreatic cancer on dynamic computed tomography (CT) and magnetic resonance (MR) imaging, and preoperative differential diagnosis is often difficult. Recently, the usefulness of diffusion-weighted MR imaging (DWI) in the diagnosis of pancreatic cancer has been reported in several studies. Purpose: To determine whether high-b-value DWI can distinguish pancreatic cancer from benign mass-forming chronic pancreatitis. Material and Methods: Twenty pancreatic cancers and four cases of mass-forming chronic pancreatitis were evaluated by high-b-value DWI (b=800 s/mm2). The signal intensity on DWI was visually evaluated, and the isotropic apparent diffusion coefficients (ADCs) were measured. Results: All twenty pancreatic cancers showed high signal intensity (18 showed very high, two showed slightly high) on DWI. None of the mass-forming chronic pancreatitis cases showed very high intensity (three showed iso to low, one showed slightly high) on DWI. The ADCs in the pancreatic cancer and mass-forming chronic pancreatitis were 1.38+-0.32x10-3 mm2/s and 1.0 0.18x10-3 mm2/s, respectively (P<0.05). Conclusion: On high-b-value DWI, most pancreatic cancers showed very high signal intensity, and may hence be distinguished from benign mass-forming chronic pancreatitis based on our preliminary results

    Chronic intractable pain is a common problem in severe pancreatic disease. Bilateral thoracoscopic splanchnotomy, a thoracoscopic neurotomy of the splanchnic nerves, is rarely performed but may provide significant pain relief in these patients. We present a safe strategy that uses prone positioning and two thoracoscopic ports for either hemithorax, permitting easy exposure and simple dissection of the greater and lesser splanchnic nerves. In our experience, this technique provides excellent pain relief with a minimal postoperative stay and few postoperative adverse events. This intervention has the potential to reduce dependency on opioid agents and improve quality of life in carefully selected patients. PMID:26897240

    Endoscopic ultrasonography (EUS) is well suited for assessment of the pancreas due to its high resolution and the proximity of the transducer to the pancreas, avoiding air in the gut. Evaluation of chronic pancreatitis (CP) was an early target for EUS, initially just for diagnosis but later for therapeutic purposes. The diagnosis of CP is still accomplished using the standard scoring based on nine criteria, all considered to be of equal value. For diagnosis of any CP, at least three or four criteria must be...

  11. Neurodegenerative properties of chronic pain: cognitive decline in patients with chronic pancreatitis.

    Directory of Open Access Journals (Sweden)

    Marijtje L A Jongsma

    Full Text Available Chronic pain has been associated with impaired cognitive function. We examined cognitive performance in patients with severe chronic pancreatitis pain. We explored the following factors for their contribution to observed cognitive deficits: pain duration, comorbidity (depression, sleep disturbance, use of opioids, and premorbid alcohol abuse. The cognitive profiles of 16 patients with severe pain due to chronic pancreatitis were determined using an extensive neuropsychological test battery. Data from three cognitive domains (psychomotor performance, memory, executive functions were compared to data from healthy controls matched for age, gender and education. Multivariate multilevel analysis of the data showed decreased test scores in patients with chronic pancreatitis pain in different cognitive domains. Psychomotor performance and executive functions showed the most prominent decline. Interestingly, pain duration appeared to be the strongest predictor for observed cognitive decline. Depressive symptoms, sleep disturbance, opioid use and history of alcohol abuse provided additional explanations for the observed cognitive decline in some of the tests, but to a lesser extent than pain duration. The negative effect of pain duration on cognitive performance is compatible with the theory of neurodegenerative properties of chronic pain. Therefore, early and effective therapeutic interventions might reduce or prevent decline in cognitive performance, thereby improving outcomes and quality of life in these patients.

    2011-01-01

    Full Text Available Context Intraductal papillary mucinous neoplasms (IPMNs are a recently classified pancreatic neoplasm with an increasing incidence. IPMN is often misdiagnosed as chronic pancreatitis because of symptoms of relapsing abdominal pain, pancreatitis, and steatorrhea and imaging findings of a dilated pancreatic duct of cystic lesions that are frequently confused with pseudocysts. Early recognition of IPMN allows for prompt surgical resection before malignant transformation. Case reports We report two cases of patients with long histories of chronic pancreatitis (more than 15 years that went on to develop IPMN. Both patients presented with symptoms of abdominal pain, nausea, steatorrhoea and eventually weight loss. Biochemical and radiological findings were suggestive of chronic pancreatitis although no clear causes for this were identified. Both patients were followed up with multiple repeat scans with no reported sinister findings. Many years after the initial diagnosis of chronic pancreatitis, radiological investigations identified pathological changes suggestive of neoplastic development and histology confirmed IPMN. Conclusions The cases demonstrate the ongoing challenges in diagnosing and managing IPMN effectively; highlights the important aspects of epidemiology in differentiating chronic pancreatitis and IPMN; continues the discussion surrounding the relationship between IPMN and chronic pancreatitis.

  13. Radiodiagnostics for carcinoma of the pancreas and chronic pancreatitis

    International Nuclear Information System (INIS)

    The purpose of this study is to establish which methods in radiodiagnosis are the most effective in demonstrating the presence of a pancreatic carcinoma or chronic pancreatitis. A second purpose is to evaluate which methods can be used to plan treatment of the patient. The different methods of radiodiagnosis that have been used and are being used to demonstrate disease of the pancreas are described, and their possible applications are reviewed. From this review a scheme is devised for the radiodiagnostic investigation of pancreatic disease. The results of each method of investigation are evaluated for those patients who were investigated in the University Hospital Groningen and compared with those published in the literature. On the basis of the results a final scheme for the diagnostic process is outlined. Ultrasonography and endoscopic pancreaticocholangiography are the prime methods of radiological investigation. Arteriography is an essential method in the assessment of the curative operability. It is established that computerized tomography is of little value after a good ultrasonogram, both for the primary diagnosis and the assessment of the possibility for operative treatment. (Auth.)

    Full Text Available Diagnosis of chronic pancreatitis (CP remains a challenge. Endoscopic ultrasound (EUS can be considered nowadays as the technique of choice for the morphological diagnosis of this disease. More than three or four EUS defined criteria of CP need to be present for the diagnosis of the disease. The development of the more restrictive Rosemont classification aims to standardize the criteria, assigning different values to different features but its impact on the EUS-based diagnosis of CP is debatable. A combined use of endoscopic function test and EUS has even increased the diagnostic yield. Elastography and FNA may be also of help for diagnosing CP. EUS also provides with very valuable information on the severity of the disease, giving key information that may influence in the treatment. Differential diagnosis of solid pancreatic masses in the context of a CP is also challenging, EUS plays a key role in this context. It provides with the possibility of obtaining specimens for histopathological diagnosis. Nowadays, new developed techniques associated to EUS, like elastography and contrast enhancement, are also showing promising results for the differentiating between these pancreatic lesions.

    AIM:To assess the role of magnetic resonance cholangiopancreatography (MRCP) in detection of pancreatic duct stones (PDS) in patients with chronic pancreatitis (CP).METHODS:Clinical data of 78 CP patients who were treated at the First Affiliated Hospital of Xi'an Jiaotong University (China) between January 2004 and July 2008 were retrospectively analyzed. A predictive model of pancreatic duct stones was established through logistic regression and its effectiveness was verified. Among these patients, MRCP was performed in 60 patients who served as a control group, while 44 patients with a higher predictive value than the entry threshold of the predictive model served as an experimental group.RESULTS:The positive rate of PDS in the 78 patients with CP was 19.2% (15/78). The predictive entry threshold of the predictive model was 5% ( P < 0.05). The possibility of existence of PDS could be predicted according to the following 4 indexes:gastrointestinal symptoms, intermittent abdominal pain, diabetes mellitus (DM)/impaired glucose tolerance (IGT) and positive B-mode ultrasound results. The incidence of PDS in the experimental group was higher than that in the control group ( P < 0.05). CONCLUSION:MRCP is strongly suggested for the detection of PDS in patients with gastrointestinal symptoms, intermittent abdominal pain, DM/IGT and positive B-mode ultrasound results.

    Chronic pancreatitis (CP) is a devastating disease with no treatments. Experimental models have been developed to reproduce the parenchyma and inflammatory responses typical of human CP. For the present study, one objective was to assess and compare the effects of pancreatic duct ligation (PDL) to those of repetitive cerulein (Cer)-induced CP in mice on pancreatic production of bone morphogenetic protein-2 (BMP2), apelin, and parathyroid hormone-related protein (PTHrP). A second objective was to determine the extent of cross talk among pancreatic BMP2, apelin, and PTHrP signaling systems. We focused on BMP2, apelin, and PTHrP since these factors regulate the inflammation-fibrosis cascade during pancreatitis. Findings showed that PDL- and Cer-induced CP resulted in significant elevations in expression and peptide/protein levels of pancreatic BMP2, apelin, and PTHrP. In vivo mouse and in vitro pancreatic cell culture experiments demonstrated that BMP2 stimulated pancreatic apelin expression whereas apelin expression was inhibited by PTHrP exposure. Apelin or BMP2 exposure inhibited PTHrP expression, and PTHrP stimulated upregulation of gremlin, an endogenous inhibitor of BMP2 activity. Transforming growth factor-β (TGF-β) stimulated PTHrP expression. Together, findings demonstrated that PDL- and Cer-induced CP resulted in increased production of the pancreatic BMP2, apelin, and PTHrP signaling systems and that significant cross talk occurred among pancreatic BMP2, apelin, and PTHrP. These results together with previous findings imply that these factors interact via a pancreatic network to regulate the inflammation-fibrosis cascade during CP. More importantly, this network communicated with TGF-β, a key effector of pancreatic pathophysiology. This novel network may be amenable to pharmacologic manipulations during CP in humans.

    This paper reviews the current literature on chronic pancreatitis (CP). Despite marked progress in diagnostic tools, predominately imaging methods, no consensus has been reached on the nomenclature of CP, ie diagnosis, classification, staging, pathomechanisms of pain and its optimal treatment. A major problem is that no single reliable diagnostic test exists for early-stage CP except histopathology (rarely available). This stage is characterised typically by recurrent acute pancreatitis +/- necrosis (eg pseudocysts). Acute pancreatitis is a well-defined condition caused in 80% of cases by gallstones or alcohol abuse. Alcoholic pancreatitis, in contrast to biliary pancreatitis, progresses to CP in the majority of patients. However, a definite CP-diagnosis is often delayed because progressive dysfunction and/or calcification, the clinical markers of CP, develop on average 5 years from disease onset. The progression rate is variable and depends on several factors eg aetiology, smoking, continued alcohol abuse. Repeated function testing eg by the faecal elastase test, is the best alternative for histology to monitor progression (or non-progression) of suspected (probable) to definite CP. The pathomechanism of pain in CP is multifactorial and data from different series are hardly comparable mainly because insufficient data of the various variables ie diagnosis, classification, staging of CP, pain pattern and presumptive pain cause, are provided. Pain in CP is rarely intractable except in the presence of cancer, opiate addiction or extra-pancreatic pain causes. Local complications like pseudocysts or obstructive cholestasis are the most common causes of severe persistent pain which can be relieved promptly by an appropriate drainage procedure. Notably, partial to complete pain relief is a common feature in 50-80% of patients with late-stage CP irrespective of surgery and about 50% of CP-patients never need surgery (or endoscopic intervention).

  5. Diagnosis of pancreatic ductal adenocarcinoma and chronic pancreatitis by measurement of microRNA abundance in blood and tissue.

    Directory of Open Access Journals (Sweden)

    Andrea S Bauer

    Full Text Available A solid process for diagnosis could have a substantial impact on the successful treatment of pancreatic cancer, for which currently mortality is nearly identical to incidence. Variations in the abundance of all microRNA molecules from peripheral blood cells and pancreas tissues were analyzed on microarrays and in part validated by real-time PCR assays. In total, 245 samples from two clinical centers were studied that were obtained from patients with pancreatic ductal adenocarcinoma or chronic pancreatitis and from healthy donors. Utilizing the minimally invasive blood test, receiver operating characteristic (ROC curves and the corresponding area under the curve (AUC analysis demonstrated very high sensitivity and specificity of a distinction between healthy people and patients with either cancer or chronic pancreatitis; respective AUC values of 0.973 and 0.950 were obtained. Confirmative and partly even more discriminative diagnosis could be performed on tissue samples with AUC values of 1.0 and 0.937, respectively. In addition, discrimination between cancer and chronic pancreatitis was achieved (AUC = 0.875. Also, several miRNAs were identified that exhibited abundance variations in both tissue and blood samples. The results could have an immediate diagnostic value for the evaluation of tumor reoccurrence in patients, who have undergone curative surgical resection, and for people with a familial risk of pancreatic cancer.

    Pancreatic ductal adenocarcinoma (PDAC) is characterized by a fibrotic and inflammatory microenvironment that is formed primarily by activated, myofibroblast-like, stellate cells. Although the stellate cells are thought to contribute to tumorigenesis, metastasis and drug resistance of PDAC, the signaling events involved in activation of the stellate cells are not well defined. Functioning as transcription co-factors, Yes-associated protein (YAP) and its homolog transcriptional co-activator with PDZ-binding motif (TAZ) modulate the expression of genes involved in various aspects of cellular functions, such as proliferation and mobility. Using human tissues we show that YAP and TAZ expression is restricted to the centroacinar and ductal cells of normal pancreas, but is elevated in cancer cells. In particular, YAP and TAZ are expressed at high levels in the activated stellate cells of both chronic pancreatitis and PDAC patients as well as in the islets of Langerhans in chronic pancreatitis tissues. Of note, YAP is up regulated in both acinar and ductal cells following induction of acute and chronic pancreatitis in mice. These findings indicate that YAP and TAZ may play a critical role in modulating pancreatic tissue regeneration, neoplastic transformation, and stellate cell functions in both PDAC and pancreatitis.

    Background Several previous studies have shown that diffusion-weighted imaging (DWI) can provide additional information for focal pancreatic lesions by demonstrating more restricted diffusion in solid malignant tumors than in chronic pancreatitis,which can be indicated by a decreased apparent diffusion coefficient (ADC).However,these studies have a modest sample size and convey inconclusive results.The aim of this study was to determine,in a meta-analysis,the diagnostic performance of quantitative diffusion-weighted magnetic resonance imaging in distinguishing pancreatic carcinoma from mass-forming chronic pancreatitis.Methods We determined the sensitivities and specificities across studies.A summary receiver operator characteristic (sROC) curve was constructed to calculate the area under the curve (AUC).Results The pooled sensitivity of DWI was 0.86 (95% CI:0.80-0.91) and the pooled specificity was 0.82 (95% CI:0.72-0.89).The AUC of the sROC was 0.91 (95% CI:0.88-0.93).Conclusions DWI may be a potentially technically feasible tool for differentiating pancreatic carcinoma from massforming chronic pancreatitis.However,large-scale randomized control trials are necessary to assess its clinical value.

  8. CT classification of chronic pancreatitis and the significance for differential diagnosis

    International Nuclear Information System (INIS)

    Objective: To study the CT characteristics of chronic pancreatitis and a classification based on the CT manifestations was established. Methods: In total 59 patients with chronic pancreatitis, 43 males and 16 females, with an average age of 40 years old were enrolled in the study. History of acute pancreatitis was positive in 36 patients. Non contrast enhanced and contrast enhanced CT scans were performed. The sizes of lesions, contour of pancreas, as well as the number, density and margin of lesions were investigated on the CT images. Results: Atrophy of the entire pancreas was revealed in 27 patients (46%), complicated with different degree of calcification. Solitary cyst with amorphous wall calcification was demonstrated in 13 patients (22%); multiple intra-pancreatic and peri-pancreatic pseudo-cysts were shown in 7 patients (12%); dilated pancreatic duct was seen in 7 patients (12%); and regional well demarcated bulging of pancreas was presented in 5 patients (8%). Conclusion: The CT findings of chronic pancreatitis in our study could be classified into 5 types: atrophy type, solitary cystic type, multicystic type, pure pancreatic duct dilatation type and mass type. The classification had certain significance for the differential diagnosis and the etiological analysis of chronic pancreatitis. (authors)

  9. Extracorporeal shock wave lithotripsy on pancreatic duck stones in patients with chronic pancreatitis: evaluation of therapeutic results with CT

    International Nuclear Information System (INIS)

    To demonstrate by CT scanning the effect of extracorporeal shock wave lithotripsy (ESWL) on pancreatic duct stones in patients with chronic pancreatitis. Pancreatic duct stones in 11 patients with chronic pancreatitis were subject to ESWL using an electrohydraulic lithotripter. Endoscopic stone removal using a basket had failed in ten patients, and in one, endoscopy was impossible due to a previous Whipple's operation. CT scans obtained before and after ESWL were evaluated by two radiologists: the longest and shortest diameters of the target stone were measured, and according to the degree of fragmentation, determined by comparing the area of the stone before and after ESWL, a grade (1-5) was assigned. In each case, the pre- and post- treatment diameter of the main pancreatic duct, measured at the pancreatic body, was also compared. Disintegration of the target stone was achieved in all patients: grade 1 (over 75% of the area remained, compared with that of the initial stone) was assigned in two patients; grade 2 (51-75% of the original area) in one; grade 3 (26-50%) in four; grade 4 (under 25%) in two; and grade 5 (complete clearance of the target stone) in two. The mean area decreased from 175 mm2 to 69 mm2 after ESWL (p<0.05); a decrease of more than 50% was observed in eight patients (73%). The mean diameter of the main pancreatic duct decreased from 7.36 to 4.81 mm (p<0.05). No severe adverse effects or complications were noted, and all patients showed clinical improvement. Follow-up studies indicated that pancreatic duct stones recurred in three patients. ESWL can cause the fragmentation of pancreatic duct stones without significant complications, and should be considered where endoscopic stone removal has failed. CT is a suitable non-invasive and accurate tool for evaluating the therapeutic results of ESWL

    Full Text Available GNMT: glycine N-methyltransferase; SAH: Sadenosylhomocysteine; SAM: S-adenosylmethionine Dear Sir, The comprehensive review by Braganza and Dormandy on micronutrient therapy for chronic pancreatitis included emphasis on the role of methyl group and thiol metabolism [1]. I am writing to expand on the comments expressed in the letter by Rajesh et al. [2] and the reply by Dr. Braganza [3] in the July issue of JOP. Journal of the Pancreas (Online. These have served to highlight the results reported by Girish et al. in which they suggest that a deficiency of methyl groups may be a factor in the development of pancreatitis [4]. In their letter, Rajesh et al. cite our paper showing that pancreatic secretion in rats is compromised in folate deficiency [2]. There is a close relationship between folate and methyl group metabolism. Folate is required for the de novo synthesis of methyl groups. The ratio of Sadenosylmethionine (SAM to S-adenosylhomocysteine (SAH is regulated by the enzyme glycine Nmethyltransferase (GNMT under the control of a specific form of folate [5]. GNMT is very abundant in the exocrine cells of the pancreas [6] and in a subsequent publication we showed that SAM plays an important role in the secretory process from pancreatic exocrine cells [7]. In that paper we provided evidence that SAM might be needed for carboxymethylation of G proteins that are needed in the process of exocytosis. It should also be noted that the process of exocytosis involves the fusion and regeneration of membranes that are generated in the Golgi and the rough endoplasmic reticulum [8]. Tissues that are actively involved in exocrine secretion may then have an increased requirement for synthesis of phosphatidylcholine, an important component of the plasma membrane. There are two pathways that are used for the synthesis of phosphatidylcholine. The major pathway in most tissues utilizes preformed choline reacting with cytidine triphosphate to eventually form

  13. Congenital anomalies, hereditary diseases of the pancreas, acute and chronic pancreatitis

    International Nuclear Information System (INIS)

    The most important congenital anomalies include pancreas divisum, annular pancreas and ectopic pancreas. Patients with pancreas divisum may be more susceptible to acute or chronic pancreatitis and patients with an annular pancreas may develop duodenal stenosis. In pancreas divisum the key finding is the visualization of the main duct draining into the duodenum via the small papilla, separated from the common bile duct. Annular pancreas may show as a well defined ring of pancreatic tissue that encircles the duodenum. Ectopic pancreas is usually asymptomatic but may give rise to abdominal complaints and may be confused with submucosal tumors. Acute pancreatitis is classified as mild or severe. In mild forms ultrasound is the imaging modality of choice whereas in severe forms with extensive pancreatic and peripancreatic necroses computed tomography is the favored method. It is crucial to identify signs and criteria that come along with an increased risk of infection of the necroses. MRI plays an inferior role in the assessment of acute pancreatitis. Chronic pancreatitis is a longstanding inflammatory and fibrosing process causing pain and loss of function. Cross-section imaging is particularly in demand for the detection of complications and the differentiation from pancreatic cancer. Autoimmune pancreatitis is a unique form of chronic pancreatitis characterized by lymphoplasmacytic infiltration and fibrosis, and favourable response to corticosteroid treatment. (orig.)

    The pathogenesis of pain in chronic pancreatitis is poorly understood, and its treatment can be a major clinical challenge. Surgical and other invasive methods have variable outcomes that can be unsatisfactory. Therefore, there is a great need for further discovery of the pathogenesis of pancreatitis pain and new therapeutic targets. Human and animal studies indicate a critical role for oxidative stress and activation of transient receptor potential (TRP) cation channel subfamily members TRPV1 and TRPA1 on pancreatic nociceptors in sensitization mechanisms that result in pain. However, the in vivo role of transient receptor potential cation channel subfamily V member 4 (TRPV4) in chronic pancreatitis needs further evaluation. The present study characterized a rat alcohol/high fat diet (AHF)-induced chronic pancreatitis model with hypersensitivity, fibrotic pathology, and fat vacuolization consistent with the clinical syndrome. The rats with AHF-induced pancreatitis develop referred visceral pain-like behaviors, i.e. decreased hindpaw mechanical thresholds and shortened abdominal and hindpaw withdrawal latency to heat. In this study, oxidative stress was characterized as well as the role of TRPV4 in chronic visceral hypersensitivity. Lipid peroxidase and oxidative stress were indicated by increased plasma thiobarbituric acid reactive substances (TBARS) and diminished pancreatic manganese superoxide dismutase (MnSOD). The secondary sensitization associated with AHF-induced pancreatitis was effectively alleviated by the TRPV4 antagonist, HC 067047. Similarity of the results to those with the peripherally restricted μ-opiate receptor agonist, loperamide, suggested TRPV4 channel activated peripheral sensitization. This study using a reliable model that provides pre-clinical correlates of human chronic pancreatitis provides further evidence that TRPV4 channel is a potential therapeutic target for treatment of pancreatitis pain.

    Full Text Available Context Chronic pancreatitis is common in India. However, its risk factors are not clear. There is sparse data on the current prevalence of tropical pancreatitis in India. Objective To undertake a prospective nationwide study of the risk factors and clinical profile of chronic pancreatitis. Setting Thirty-two major centers from different regions of India contributed data on 1,086 patients to a common online website (www.ipans.org. Main outcome measures Risk factors, clinical features complications and treatment of chronic pancreatitis. Results Of the 1,086 subjects, complete data on risk factors were available for 1,033 subjects. Idiopathic pancreatitis was the most common form of pancreatitis (n=622; 60.2% and alcoholic chronic pancreatitis accounted for about a third of the cases (n=400; 38.7%; the rest (n=11; 1.1% had rare risk factors. Smoking and cassava intake were documented in 292 (28.3% and 189 (18.3% subjects, respectively. Using well-defined criteria, only 39 (3.8%cases could be labeled as ‘tropical pancreatitis’. Pain occurred in 971 patients (94.0%. Four hundred and eighteen (40.5% subjects had diabetes mellitus. Of alcohol consumers, alcoholism and female gender were independent risk factors for diabetes in subjects with chronic pancreatitis (OR=1.48, P=0.003; and OR=1.75, P<0.001, respectively. The most common complications were pseudocysts (15.8% and biliary obstruction (8.2%. Pancreatic cancer occurred in 42 subjects (4.1%. Ultrasound detected calculi in 69.7%, ductal dilatation in 63.4% and atrophy in 27.3%. The majority of patients were on medical therapy (n=849; 82.2%; endotherapy and surgery accounted for the rest. About 50% percent of the patients with diabetes required insulin (198/418. Conclusions In this first nationwide prospective survey of chronic pancreatitis in India, idiopathic pancreatitis was the most common form, followed by alcoholic pancreatitis. The classical form of tropical chronic pancreatitis is

    Full Text Available Abstract Background Chronic pancreatitis is characterized by progressive fibrosis, pain and loss of exocrine and endocrine functions. The long-standing chronic pancreatitis and its associated pancreatic fibrosis are the most common pathogenic events involved in human pancreatic carcinogenesis, but the therapeutic strategies to chronic pancreatitis and the chemoprevention of pancreatic carcinogenesis are very limited. Methods We investigated the effect of sulindac, a non-steroidal anti-inflammatory drug (NSAID, on inhibition of chronic pancreatitis in a caerulein induced chronic pancreatitis mouse model. Results Sulindac significantly reduced the severity of chronic pancreatitis including the extent of acini loss, inflammatory cell infiltration and stromal fibrosis. The protein expression of phosphorylation of MEK/ERK was inhibited in the chronic pancreatic tissues by sulindac treatment as measured by Western blot assay. The levels of inflammatory cytokines including TNF-α and MCP-1 were also significantly decreased with sulindac treatment, as well as the expression of TGF-β, PDGF-β, SHH and Gli in the chronic pancreatic tissue detected by qPCR assay and confirmed by western blot assay. The activation of pancreatic satellet cells was also inhibited by sulindac as measured by the activity of α-smooth muscle actin (α-SMA in the pancreatic tissue of chronic pancreatitis. Conclusions Sulindac is a promising reagent for the treatment of chronic pancreatitis via inhibition of inflammatory cell infiltration and stromal fibrosis, the inhibitory effect of sulindac on chronic pancreatitis may through targeting the activation ERK/MAPK signaling pathway.

    AIM: To examine surgical specimens of pancreas with either chronic pancreatitis or pancreatic cancer in order to study whether ductal hyperplasia and dysplasia in pancreas represent precursor lesions for pancreatic cancer.METHODS: We examined expression of Ki-67, CEA,p53, and K-ras, in the surgical specimens of pancreas with adenocarcinomas (n = 11) and chronic pancreatitis (n = 12). Cellular proliferation was assessed by Ki-67proliferation index using the proliferation marker Ki-67.In specimens with pancreas cancer, we divided pancreas epithelium into normal (n=7), ductal hyperplasia (n=3), dysplasia (n=4), and cancerous lesion (n=11) after hematoxylin and eosin staining, Ki-67, and CEA immunohistochemical staining. In cases with chronic pancreatitis, the specimen was pathologically examined as in cases with pancreas cancer, and they were also determined as normal (n=10), ductal hyperplasia (n=4), or dysplasia (n= 5). p53 and K-ras expression were also studied by immunohistochemical staining.RESULTS: In pancreatic cancer, the Ki-67 index was 3.73±3.58 in normal site, 6.62±4.39 in ductalhyperplasia, 13.47±4.02 in dysplasia and 37.03±10.05in cancer tissue, respectively. Overall, p53 was positive in normal ducts, ductal hyperplasia, dysplasia, and carcinoma cells in 0 of 14 (0%), 0 of 7 (0%), 7 of 9 (78%),and 10 of 11 (91%), respectively, and K-ras was positive in 0 of 8 (0%), 1 of 3 (33%), 4 of 6 (67%), 4 of 5 (80%),respectively.CONCLUSION: Our results favorably support the hypothesis that ductal hyperplasia and dysplasia of the pancreas might be precursor lesions for pancreas cancer.Further evaluation of oncogenes by the molecular study is needed.

    Full Text Available Abstract Background Second-generation intravenous blood-pool ultrasound contrast agents are increasingly used in endoscopic ultrasound (EUS for characterization of microvascularization, differential diagnosis of benign and malignant focal lesions, as well as improved staging and guidance of therapeutic procedures. Methods The aim of our study was to prospectively compare the vascularisation patterns in chronic pseudotumoral pancreatitis and pancreatic cancer using quantitative low mechanical index (MI contrast-enhanced EUS. We included 51 patients with chronic pseudotumoral pancreatitis (n = 19 and pancreatic cancer (n = 32. Perfusion imaging started with a bolus injection of Sonovue (2.4 ml, followed by analysis in the early arterial (wash-in and late venous (wash-out phase. Perfusion analysis was performed by post-processing of the raw data (time intensity curve [TIC] analysis. TIC analysis was performed inside the tumor and the pancreatic parenchyma, with depiction of the dynamic vascular pattern generated by specific software. Statistical analysis was performed on raw data extracted from the TIC analysis. Final diagnosis was based on a combination of EUS-FNA, surgery and follow-up of minimum 6 months in negative cases. Results The sensitivity and specificity of low MI contrast enhanced EUS using TIC were sensitivity and specificity of low MI contrast enhanced EUS using TIC analysis were 93.75% (95% CI = 77.77 - 98.91% and 89.47% (95% CI = 65.46 - 98.15%, respectively. Pseudotumoral chronic pancreatitis showed in the majority of cases a hypervascular appearance in the early arterial phase of contrast-enhancement, with a dynamic enhancement pattern similar with the rest of the parenchyma. Statistical analysis of the resulting series of individual intensities revealed no statistically relevant differences (p = .78. Pancreatic adenocarcinoma was usually a hypovascular lesion, showing low contrast-enhancement during the

    AIM: To determine the diagnostic accuracy of magnetic resonance (MR) pancreatography and to define its role in the imaging work-up of patients with severe chronic pancreatitis. MATERIAL AND METHODS: Thirty-two patients (13 men and 19 women; 15-84 years old; mean age, 48 years) with severe chronic pancreatitis diagnosed using cross-sectional imaging, examination using contrast medium (endoscopic retrograde cholangiopancreatography, pseudocyst injection) and/or surgical findings underwent MR pancreatography performed using a two-dimensional multi-slice fast spin echo technique. All patients underwent transabdominal pancreatic sonography and computed tomography (CT) was performed in 12 patients. Two observers independently assessed the MR pancreatograms for pancreatic duct dilatation and pancreatic duct abnormalities. Compared to the final diagnosis, the accuracy of MR pancreatography in revealing complications of chronic pancreatitis was calculated and its role in the radiological work-up of patients with chronic pancreatitis evaluated. RESULTS: When compared to the final diagnosis, MR pancreatography showed the following sensitivity, specificity and diagnostic accuracy: for filling defects in pancreatic duct, 56-78%, 100% and 87-94%, respectively; for strictures, 75-88%, 92-96% and 88-94%, respectively; and for pseudocysts 100%, 100% and 100%, respectively. Filling defects were correctly diagnosed in all patients when MR pancreatography was interpreted in combination with cross-sectional imaging. Contrast pancreatography was required for the complete evaluation of strictures and communication with pseudocysts. CONCLUSION: MR pancreatography is poorly sensitive but specific in revealing pancreatic duct filling defects and strictures. However, when MR pancreatography is interpreted in combination with sonography and CT, it provides sufficient information to plan therapy in the majority of patients. Varghese, J.C. et al. (2002)

  9. Features of Chronic Pancreatitis and Associated Masses: A Focus on Endosonography

    2014-09-01

    Full Text Available EUS is highly accurate in the diagnosis of chronic pancreatitis. Pancreatic calcifications or five or more endosonographic criteria are consistent with chronic pancreatitis. Less than three criteria essentially rules out chronic pancreatitis. Three or four criteria are the best overall cutoffs. The number of criteria is used to estimate the likelihood of pancreatitis (i.e. low/medium/high, and is not recommended to stage the severity (i.e. mild/moderate/severe of disease. Obtaining histology by FNA is not recommended in all patients with chronic pancreatitis changes. EUS is useful in distinguishing inflammatory from malignant masses in the pancreas. FNA is often not required as the EUS appearance of inflammatory changes alone or bulkiness without any perceptible mass has good negative predictive value. In indeterminate masses, FNA for cytology is recommended. Follow-up imaging after one to two months can be performed to catch the rare EUS false-negatives, and confirm resolution or stability of inflammatory masses.

    Full Text Available The study has been conducted on 39 white laboratory male rats which formed 5 groups: experimental occlusal pancreatitis caused by ligation of the main pancreatic duct (n = 6, experimental alcoholic pancreatitis caused by oral intake of alcohol (n = 6, against the background of an excess (n = 6 or deficiency (n = 6 of nitric oxide, as well as a control group (n = 15. This study provides the detailed description of the processes of death and regeneration in the islets of Langerhans, typical for early stages of the disease. The expression of the proliferation markers (PCNA and Neurogenin-3 has been analyzed using histological and immunohistochemical methods along with the changes of morphological structure, that led to initiation of the alcoholic chronic pancreatitis against the background of imbalance in NO-ergic regulatory system caused by an excess or deficiency of nitric oxide. It has been found that ligation of the pancreatic duct in the experiment reconstructedthe circumstances of chronic pancreatitis in rats and caused the activation of fibrosis and regeneration of endocrine and exocrine tissue. Compared with occlusion, the effects of ethanol on the pancreas also manifested in the activation of fibrogenesis, but the structural changes were negligible and could unlikely lead to advanced fibrosis and chronic pancreatitis in the future. On the other side, an imbalance of NO-system in alcoholic rats leads to disruption of the zymogens secretion in the acinar cells and dilatation of the capillary network in islets. Uneven distribution of zymogen granules may lead to their intracellular activation as evidenced by the deformation of acini and focal apoptosis without inflammatory response. In this case, violation of the key adaptive responses in the pancreas makes it more vulnerable to the effects of ethanol, its metabolites, and other environmental factors, and may increase the probability of chronic pancreatitis development.

    The diagnosis of a pancreatic mass lesion in the presence of chronic pancreatitis can be extremely challenging. At the same time, a high level of certainty about the diagnosis is necessary for appropriate management planning. The aim of this study was to establish current best evidence about which imaging methods reliably differentiate a benign from a malignant lesion, and show how that evidence is best applied. A diagnostic algorithm based on Bayesian analysis is proposed.

    Islet autotransplantation (IAT) is usually performed in patients undergoing pancreatic surgery for chronic pancreatitis. In the present series, IAT was offered also to patients undergoing pancreatic surgery for both nonmalignant and malignant diseases, having either completion pancreatectomy as treatment for severe pancreatic fistulas (n = 21) or extensive distal pancreatectomy for neoplasms of the pancreatic neck (n = 19) or pancreatoduodenectomy because of the high risk of pancreatic fistula (n = 32). Fifty-eight of 72 patients who were eligible to this broader spectrum of indication actually received IAT. There was no evidence of a higher-than-expected rate of major complications for pancreatectomy. Forty-five patients receiving IAT were still alive at the time of the last scheduled follow-up (1375 ± 365 days). Eighteen (95%) of 19 and 11 (28%) of 39 patients reached insulin independence after partial or total pancreatectomy, respectively. The metabolic results were dependent on the transplanted islet mass. Thirty-one of 58 patients had malignant diseases of the pancreas or periampullary region, and only three patients developed ex novo liver metastases after IAT (median follow-up 914 ± 382 days). Our data demonstrate the feasibility, efficacy, and safety of IAT for a broader spectrum of clinical indications beyond chronic pancreatitis. PMID:26695701

    Full Text Available Context Estrogens are thought to cause pancreatitis by raising triglyceride levels but whether there are other effects on the pancreas is debatable. Objective To better elucidate the relationship between estrogens and pancreatitis and pancreatic function in a pilot study. Design/setting/patients Our retrospectively collected database of 224 patients who had undergone secretin stimulation testing was queried for females with available medication histories, who were then divided into two groups: those taking estrogens (E and those not on estrogens (N. Mann Whitney U and Fisher’s exact tests were used. Results Seventy of the patients in the database were females with available medication histories. Thirty-five (50.0% were taking estrogens. Twenty-nine (82.9% of the E patients experienced any type of pancreatitis (i.e., acute pancreatitis, acute relapsing pancreatitis, chronic pancreatitis while only 19 (54.3% of the N patients did (P=0.019. During secretin stimulation testing, the peak bicarbonate levels for E and N patients were 80±18 and 90±23 mEq/L, respectively (P=0.058. When patients with any type of pancreatitis were excluded, E patients still displayed decreased peak bicarbonate levels in response to secretin (90±18 vs. 104±19 mEq/L; P=0.021. Weight, age, triglyceride levels, frequency of patients with cholecystectomy and biliary stones did not significantly differ between the two groups (E and N respectively. Conclusions These pilot data suggest exogenous estrogens may be related to the development of acute pancreatitis and acute relapsing pancreatitis, and probably to a lesser degree chronic pancreatitis, perhaps through a triglyceride independent mechanism. During secretin stimulation testing, peak bicarbonate production may be diminished in women on estrogens (even inthose who have never had pancreatitis. Further study is necessary to better define the relationship between estrogen use,pancreatitis, and pancreatic function.

    Four indices of free radical activity were measured in fasting serum/plasma samples from 14 consecutive blacks with clinically quiescent chronic pancreatitis and 15 outwardly healthy hospital personnel at Soweto, the township near Johannesburg in South Africa. The patients had higher serum levels than did controls of lipid isomerisation (P radical activity is thus a common denominator in chronic pancreatitis irrespective of geography, or putative aetiological factors whether alcoholism or idiopathic, since that ratio was approximately 95:5 at Johannesburg and 50:50 at Manchester. The further finding of subclinical oxidative stress in Sowetan controls and the endemic nature of chronic pancreatitis in that area supports the hypothesis that oxidative stress may be involved in its pathogenesis.

    Full Text Available Objective Pain is the main symptom of chronic pancreatitis. However, in addition to an improvement in pain symptoms, an increase in the quality of life also influences therapeutic success. The present paper evaluates the influence of surgery on chronic pancreatitis, and the early and late postoperative quality of life. Patients From March 2000 until April 2005, 51 patients underwent surgical treatment for chronic pancreatitis at our institution. Intervention Thirty-nine (76.5% patients were operated on according to the Frey procedure and, in 12 (23.5% patients, a Whipple procedure was performed. Study design Patient data were documented throughout the duration of the hospital stay. Postoperative follow-up data were recorded retrospectively. Main outcome measures Postoperative follow-up with postoperative pain scores and quality of life were carried out using a standardized questionnaire. Results During a median follow-up period of 50 months, an improvement in pain scores was observed in 92.3% of the patients in the Frey group and in 66.7% in the Whipple group. The indices for global quality of life and for physical and emotional status increased in both surgical groups. Conclusion For patients with chronic pancreatitis, the decisive factor is the quality of life, particularly concerning pain and metabolic changes. The Frey procedure seems to offer advantages with respect to long-term freedom of pain and low risk of surgery-induced pancreatic insufficiency.

    The authors summarised pathophysiology and therapy possibility of the chronic alcoholic pancreatitis. They introduce a new product of pancreatin use for treatment of chronic alcoholic pancreatitis. The aim of this prospective study was to asses the efficacy of this new drug in the treatment of chronic alcoholic pancreatitis. The treatment was carried out by new pancreatin product containing 10,000 FIP U lipase, 9000 FIP U amylase, and 500 FIP E protease. During the study 30 patients--suffering from alcoholic pancreatitis--were treated. They received, two tablets three times daily in a period of two weeks. The following parameters were observed and compared before and after the period of treatment: complaints of the patients, the characteristics of the stool (daily weight, frequency, fat contents, consistency) the change of the body weight and degree of abdominal pain. These parameters were compared using a score-system, before and after the period of treatment. The authors could analyse the data of 21 patients. It was proved that there was a significant decrease in frequency, daily weight and fat contents of the stool and in abdominal pain. There was not significant change in the body weight. The authors concluded that this new product is a good pancreatin preparation which is useful and suitable for effective treatment of chronic alcoholic pancreatitis, if the patient keeps abstinence.

    One of the most common symptoms presenting in patients with chronic pancreatitis is pancreatic-type pain. Obstruction of the main pancreatic duct in chronic pancreatitis can be treated by a multitude of therapeutic approaches, ranging from pharmacologic, endoscopic and radiologic treatments to surgical interventions. When the conservative treatment approaches fail to resolve symptomatic cases, however, endoscopic retrograde pancreatography with pancreatic duct drainage is the preferred second approach, despite its well-recognized drawbacks. When the conventional transpapillary approach fails to achieve the necessary drainage, the patients may benefit from application of the less invasive endoscopic ultrasound (EUS)-guided pancreatic duct interventions. Here, we describe the case of a 42-year-old man who presented with severe abdominal pain that had lasted for 3 mo. Computed tomography scanning showed evidence of chronic obstructive pancreatitis with pancreatic duct stricture at genu. After conventional endoscopic retrograde pancreaticography failed to eliminate the symptoms, EUS-guided pancreaticogastrostomy (PGS) was applied using a fully covered, self-expandable, 10-mm diameter metallic stent. The treatment resolved the case and the patient experienced no adverse events. EUS-guided PGS with a regular biliary fully covered, self-expandable metallic stent effectively and safely treated pancreatic-type pain in chronic pancreatitis. PMID:27099862

    Full Text Available Context Acute and chronic pancreatitis may present with pseudocysts in atypical locations. Activated pancreatic enzymes track along anatomic fascial planes causing digestion of the surrounding tissues and resulting in distant pseudocysts. Pseudocysts at atypical locations pose significant diagnostic as well as therapeutic challenges. Case report We report an unusual presentation of a pancreatic pseudocyst in a young male who presented with a left perinephric abscess. Percutaneous drainage was not successful in resolving the abscess and he was subsequently diagnosed as having chronic pancreatitis together with a left perinephric abscess. Needle knife sphincterotomy of the ampulla of Vater resulted in the gradual resolution of the abscess. Conclusion We report a rare presentation of chronic pancreatitis with a perinephric abscess and its non-surgical management. This case report indicates that any patient presenting with a perinephric abscess of unknown etiology not responding to conventional treatment modalities should be investigated for underlying pancreatitis.

    2010-09-01

    Full Text Available Context Pancreatic heterotopia is a rare pathologic entity, previously reported in the stomach, duodenum and jejunum. It is mostly asymptomatic and rarely gives rise to complications. Localization of pancreatic heterotopia in the gallbladder is extremely rare and can be associated with cholecystitis or cholecystolithiasis. Case report We herein describe a case of a 39-year-old man who presented with biliary type pain with ultrasonographic evidence of a gallbladder polyp. Laparoscopic cholecystectomy was performed with uneventful recovery. Pathologic examination of the gallbladder detected a heterotopic focus of pancreatic tissue in its wall, associated with chronic cholecystitis with no gallstones. Conclusion Pancreatic heterotopia of the gallbladder is a very rare entity with unknown clinical significance. Awareness of this condition may facilitate its recognition which may shed more light on its clinical significance

    We analized the long-term results after surgical treatment in 41 patients with chronic pancreatitis. Twenty one of them underwent resection: 19 pancreaticoduodenectomy (11 Whipple procedure and 8 Traverso Longmire); total pancreatectomy (1) and near-total pancreatectomy (1). In the remaining 20 patients a drainage procedure was carried out: Puestow-Duval (5); Partington (7); double derivation: pancreatic and biliar (5); triple derivation: pancreatic, biliar, gastric (2) and Nardi procedure+quisteduodenostomy in one patient. The following were evaluated: persistent pain; chronic alcoholism; nutrition status; exocrine function (syntomatic steatorrea, use of pancreatic enzyme preparation and fecal determination of glucide, protids and lipids) and endocrine function (glucose and insulin levels and glucose oral test). Surgery failed to relieve pain in 15.6% of the patients; failures were associated chronic alcoholism (p < 0.05); 18 patients (44%) required oral pancreatic enzymes. There weren't significant differences between resection and drainage procedures regarding the exocrine function. However, endocrine function was significantly worse (p < 0.05) after pancreaticoduodenectomy than after drainages procedures. Among the late, the endocrine function was better after Partington operation than after the Puestow-Duval. PMID:7946606

    Diabetes mellitus (DM) is a great public health problem, which attacks part of the world population, being characterized by an imbalance in body glucose homeostasis. Physical exercise is pointed as a protective agent and is also recommended to people with DM. As pancreatic islets present an important role in glucose homeostasis, we aim to study the role of physical exercise (chronic adaptations and acute responses) in pancreatic islets functionality in Wistar male rats. First, animals were divided into two groups: sedentary (S) and aerobic trained (T). At the end of 8 weeks, half of them (S and T) were submitted to an acute exercise session (exercise until exhaustion), being subdivided as acute sedentary (AS) and acute trained (AT). After the experimental period, periepididymal, retroperitoneal and subcutaneous fat pads, blood, soleus muscle and pancreatic islets were collected and prepared for further analysis. From the pancreatic islets, total insulin content, insulin secretion stimulated by glucose, leucine, arginine and carbachol were analyzed. Our results pointed that body adiposity and glucose homeostasis improved with chronic physical exercise. In addition, total insulin content was reduced in group AT, insulin secretion stimulated by glucose was reduced in trained groups (T and AT) and insulin secretion stimulated by carbachol was increased in group AT. There were no significant differences in insulin secretion stimulated by arginine and leucine. We identified a possible modulating action on insulin secretion, probably related to the association of chronic adaptation with an acute response on cholinergic activity in pancreatic islets.

  20. Gallbladder emptying evaluation in calcific chronic pancreatitis using Tc-99m DISIDA scintigraphy

    International Nuclear Information System (INIS)

    The aim of this study was to analyze the gallbladder motor function in chronic pancreatitis (C) patients. Gallbladder emptying was evaluated in 11 patients, without and with addition of pancreatic extract and in ten controls. The results were compared and analyzed statistically. The ejection fraction (E F) of the gallbladder (GB) at 30, 45 and 60 minutes were calculated by using Tc-9 9 m DISIDA scintigraphy. The E F of GB at 60 minutes was significantly higher in the controls when compared to patients, although the results between patients were similar without and with addition of pancreatic extract. The results suggest that the delay in the GB emptying does not depend on the eventual alteration in the intestinal phase of the vesicular stimulation, but it probably results from a mechanic factor, which depends on the chronic pathological process located in the head of the pancreas.

    Full Text Available Context Choledochal cysts, rarely present with chronic calcific pancreatitis. We report two patients with choledochal cysts who had concomitant chronic pancreatitis. Case report #1 A 27-year-old female with a history of recurrent abdominal pain, fever and jaundice presented with a type I choledochal cyst with calcifications in the uncinate process of the pancreas on CT scan. Her magnetic resonance cholangiopancreatogram (MRCP revealed calcifications in the region of the uncinate process of the pancreas, the presence of a type I choledochal cyst with dilatation of the right and left hepatic ducts at their confluence suggesting an anomalous pancreaticobiliary ductal junction. She underwent choledochal cyst excision with a Roux-en-Y hepaticojejunostomy. Case report #2 A 35-year-old male with colicky abdominal pain of four months duration whose CT scan was suggestive of an atrophic pancreas with a 1 cm dilatation of the pancreatic duct and a calculus in the pancreatic duct near the ampulla. MRCP showed significant atrophy of the pancreas with an isointense filling defect seen in the pancreatic duct at its distal end near the ampulla. A diagnosis of chronic calcific pancreatitis with type I choledochal cyst was made. He underwent choledochal cyst excision with a cholecystectomy, hepaticojejunostomy (end-to-side and side-to-side pancreaticojejunostomy. Conclusion Chronic calcific pancreatitis is a rare occurrence in patients with choledochal cysts and only six cases have been reported in the literature.

    Chronic pancreatitis (CP), a progressive inflammatory disease where acini are destroyed and replaced by fibrous tissue, increases the risk for pancreatic cancer. Risk factors include alcohol, smoking, and obesity. The effects of these risk factors are exacerbated in patients with mutations in genes that predispose to CP. The different environmental and genetic factors produce the same clinical phenotype; once CP develops, disease course is the same regardless of etiology. Critical questions still need to be answered to understand what modifies predisposition to develop CP in persons exposed to risk factors. We postulate that risk factors modulate endogenous pathways, with parathyroid hormone-related protein (PTHrP) signaling being one such pathway. In support, PTHrP levels are elevated in mice treated with alcohol, and in mouse models of cerulein- and pancreatic duct ligation-induced CP. Disrupting the Pthrp gene in acinar cells exerts protective effects (decreased edema, histological damage, amylase and cytokine release, and fibrosis) in these CP models. PTHrP levels are elevated in human CP. Currently, CP care lacks specific pharmacological interventions. Targeting PTHrP signaling may present a novel therapeutic strategy that inhibits pancreatic inflammation and fibrosis, especially since the risk of developing pancreatic cancer is strongly associated with duration of chronic inflammation.

  10. The Quality of Life in Chronic Pancreatitis: The Endoscopist's Point of View

    2006-01-01

    Full Text Available Due to its therapeutic properties, endoscopy can influence the quality of life (QoL of patients suffering from chronic pancreatitis (CP. Pancreatic ductal decompression represents the most frequent endoscopic procedure in patients with painful CP and it can be considered as a first-line treatment for improving the clinical condition. Endoscopy can limit surgery to unsuccessful or relapse cases. The best candidates for endoscopic treatment are patients with cephalic obstruction of the main pancreatic duct (MPD by stone(s and/or stricture(s with upstream dilation (type IV or, respectively, type V according to the Brussels or the Cambridge ERCP classification [1, 2]. These patients had pain as a consequence of an elevated intraductal pressure. Combined techniques are usually employed to remove stones and/or to dilate a stenosis, such as a pancreatic sphincterotomy, mechanic lithotripsy, extracorporeal shockwave lithotripsy (ESWL and pancreatic stent(s. Endoscopy has the potential of improving the QoL in patients with CP since it can decrease or entirely eliminate pancreatic pain and MPD dilation, two variables capable of impairing physical and mental domains [3, 4, 5]. In the Pezzilli et al. study [3], pain was the unique clinical variable able to significantly impair all physical and mental domains in a SF-36 questionnaire administered to 190 consecutive patients with proven CP.

    Full Text Available Chronic pancreatitis (CP is a progressive disorder resulting in the destruction and fibrosis of the pancreatic parenchyma which ultimately leads to impairment of the endocrine and exocrine functions. Dimethyl Fumarate (DMF was recently approved by FDA for treatment of patients with multiple sclerosis. DMF's unique anti-oxidant and anti-inflammatory properties make it an interesting drug to test on other inflammatory conditions. This study was undertaken to determine the effects of DMF on islet cells and non-endocrine tissue in a rodent model of L-Arginine-induced CP.Male Wistar rats fed daily DMF (25 mg/kg or vehicle by oral gavage were given 5 IP injections of L-Arginine (250 mg/100 g × 2, 1 hr apart. Rats were assessed with weights and intra-peritoneal glucose tolerance tests (IPGTT, 2 g/kg. Islets were isolated and assessed for islet mass and viability with flow cytometry. Non-endocrine tissue was assessed for histology, myeloperoxidase (MPO, and lipid peroxidation level (MDA. In vitro assessments included determination of heme oxygenase (HO-1 protein expression by Western blot.Weight gain was significantly reduced in untreated CP group at 6 weeks. IPGTT revealed significant impairment in untreated CP group and its restoration with DMF therapy (P <0.05. Untreated CP rats had pancreatic atrophy, severe acinar architectural damage, edema, and fatty infiltration as well as elevated MDA and MPO levels, which were significantly improved by DMF treatment. After islet isolation, the volume of non-endocrine tissue was significantly smaller in untreated CP group. Although islet counts were similar in the two groups, islet viability was significantly reduced in untreated CP group and improved with DMF treatment. In vitro incubation of human pancreatic tissue with DMF significantly increased HO-1 expression.Administration of DMF attenuated L-Arginine-induced CP and islet function in rats. DMF treatment could be a possible strategy to improve clinical

    The most important congenital anomalies include pancreas divisum, annular pancreas and ectopic pancreas. Patients with pancreas divisum may be more susceptible to acute or chronic pancreatitis and patients with an annular pancreas may develop duodenal stenosis. In pancreas divisum the key finding is the visualization of the main duct draining into the duodenum via the small papilla, separated from the common bile duct. Annular pancreas may show as a well defined ring of pancreatic tissue that encircles the duodenum. Ectopic pancreas is usually asymptomatic but may give rise to abdominal complaints and may be confused with submucosal tumors. Acute pancreatitis is classified as mild or severe. In mild forms ultrasound is the imaging modality of choice whereas in severe forms with extensive pancreatic and peripancreatic necroses computed tomography is the favored method. It is crucial to identify signs and criteria that come along with an increased risk of infection of the necroses. MRI plays an inferior role in the assessment of acute pancreatitis. Chronic pancreatitis is a longstanding inflammatory and fibrosing process causing pain and loss of function. Cross-section imaging is particularly in demand for the detection of complications and the differentiation from pancreatic cancer. Autoimmune pancreatitis is a unique form of chronic pancreatitis characterized by lymphoplasmacytic infiltration and fibrosis, and favourable response to corticosteroid treatment. (orig.)

    Full Text Available CONTEXT: Alterations of the renin-angiotensin system have been implicated in the pathogenesis of various diseases. The angiotensin converting enzyme is a key enzyme in the renin-angiotensin system. A deletion polymorphism of a 287-bp fragment of intron 16 of the angiotensin converting enzyme gene allele results in higher levels of circulating enzyme. ACE deletion genotype has been linked to heart diseases, sarcoidosis and liver fibrosis. The pancreatic renin-angiotensin system plays a role in the development of pancreatic fibrosis and ACE inhibitors decrease pancreatic fibrosis in experimental models. OBJECTIVES: We investigated the frequency of the ACE gene insertion/deletion polymorphism in chronic pancreatitis patients and controls. PATIENTS: Subjects with familial pancreatitis (n=51, sporadic chronic pancreatitis (n=104, and healthy controls (n=163 were evaluated. MAIN OUTCOME MEASURE: The presence of ACE insertion/deletion polymorphism. RESULTS: The frequency of the ACE gene deletion allele was similar in familial pancreatitis (49.0% sporadic pancreatitis (51.0% and controls (55.8%. Furthermore, there was no significant difference in clinical features between patients with ACE-insertion or insertion/deletion genotypes vs. patients with ACE-deletion genotype. CONCLUSION: We conclude that the ACE deletion genotype does not make a significant contribution to the pathogenesis and the progression of chronic pancreatitis.

    Introduction Chronic pancreatitis (CP) is an intractable and multi-factorial disorder. Developing appropriate animal models is an essential step in pancreatitis research, and the best ones are those which mimic the human disorder both aetiologically and pathophysiologically. The current study presents an optimised protocol for creating a murine model of CP, which mimics the initial steps of chronic pancreatitis in alcohol chronic pancreatitis and compares it with two other mouse models treated with cerulein or ethanol alone. Material and methods Thirty-two male C57BL/6 mice were randomly selected, divided into four groups, and treated intraperitoneally with saline (10 ml/kg, control group), ethanol (3 g/kg; 30% v/v), cerulein (50 µg/kg), or ethanol + cerulein, for six weeks. Histopathological and immunohistochemical assays for chronic pancreatitis index along with real-time PCR assessments for mRNA levels of inflammatory cytokines and fibrogenic markers were conducted to verify the CP induction. Results The results indicated that CP index (CPI) was significantly increased in ethanol-cerulein mice compared to the saline, ethanol, and cerulein groups (p < 0.001). Interleukin 1β (IL-1β), tumor necrosis factor α (TNF-α), transforming growth factor β (TGF-β), α-smooth muscle actin (α-SMA), and myeloperoxidase activity were also significantly greater in both cerulein and ethanol-cerulein groups than in the saline treated animals (p < 0.001). Immunohistochemical analysis revealed enhanced expression of TGF-β and α-SMA in ethanol-cerulein mice compared to the saline group. Conclusions Intraperitoneal (IP) injections of ethanol and cerulein could successfully induce CP in mice. IP injections of ethanol provide higher reproducibility compared to ethanol feeding. The model is simple, non-invasive, reproducible, and time-saving. Since the protocol mimics the initial phases of CP development in alcoholics, it can be used for investigating basic mechanisms and testing

    In conclusion, surgical therapy in patients with chronic pancreatitis may be characterized as follows: 1. Independently, several investigators have found intraductal and intraparenchymatous hypertension in patients with chronic pancreatitis. Decompression of the ductal system as the main principle of surgical therapy achieves clinical pain relief in most patients with chronic pancreatitis. The precondition is a consequent drainage of the main pancreatic duct and tributary ducts of second and third order up to the prepapillary region. The presence of an inflammatory tumor in the head of the pancreas or ductal abnormalities in the prepapillary region or a pancreas divisum requires performance of an extended drainage operation (LPJ-LPHE) to achieve pain relief and an improved quality of life. An extended drainage operation effectively manages complications arising from adjacent organs, such as distal common bile duct stenosis, segmental duodenal stenosis, and internal pancreatic fistulas. The extent of decompression has to be tailored to the anatomic and morphologic situation of the patient. 2. In patients with chronic pancreatitis, the main pancreatic duct is usually dilated. A small duct (3-5 mm) is only small for the surgeon. For the sclerosing entity of chronic pancreatitis with a truly small duct, that is, less than 3 mm in diameter ("small duct disease"), a longitudinal V-shaped excision of the ventral pancreas, as opposed to left resection, provides a new perspective for a sufficient drainage. 3. In the presence of segmental portal hypertension, a simple or extended drainage operation does not result in a normalization of the portal venous blood flow; however, how often relevant upper gastrointestinal hemorrhage develops from segmental portal hypertension is unclear. Therefore, the clinical relevance of this special problem needs further evaluation. 4. Postoperative morbidity of LPJ-LPHE is significantly lower in comparison to resectional procedures, such as PD

    Full Text Available Alcoholic pancreatitis continues to stir up controversy. One of the most debated points is whether from onset it is a chronic disease or whether it progresses to a chronic form after repeated episodes of acute pancreatitis. Histological studies on patients with alcoholic pancreatitis have shown that the disease is chronic from onset and that alcoholic acute pancreatitis occurs in a pancreas already damaged by chronic lesions. Genetic factors may also play a role in the pathogenesis of alcoholic disease. The incidence of chronic alcoholic pancreatitis seems to have decreased in the last twenty years. Finally, recent therapeutic studies which have shown medical or surgical approaches capable of reducing the pain episodes in chronic pancreatitis patients will be described.

    The aim of this study was to establish the correlation between the occurrence of Q705K and F359L polymorphisms in patients diagnosed with pancreatic diseases and periodontal conditions of various degrees of severity. The above-mentioned genetic markers were assessed in patients with pancreatic cancer (n = 18) and chronic pancreatitis (n = 39) as well as in a healthy control group (n = 115). The established inclusion criteria were the following: Caucasian descent, non-smoking, and age range 20-80, with different levels of periodontitis activity according to S. Offenbacher's scale. The genotyping reactions were performed by means of an RT-PCR with the use of TaqMan(®) genotyping assay. Results of the study revealed that the state of periodontium was significantly worse in patients with chronic pancreatitis. The Q705K and F359L polymorphisms were associated with more advanced cases of periodontitis measured by clinical attachment level, whereas the Q705K was associated with intensified bleeding index. Furthermore, the F359L single-nucleotide polymorphism was significantly higher in the group with chronic pancreatitis (p < 0.0001; OR = 6.8571). Whereas, the prevalence of Q705K polymorphism was higher in the group of pancreatic cancer (p = 0.107; OR = 3.3939). This study suggests that the exaggerated inflammatory response provoked by Q705K and F359L might be the common denominator for periodontitis, pancreatic cancer, and chronic pancreatitis. These findings might constitute the basis for a new diagnostic and therapeutic approach. PMID:26253076

    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.

    Thirty patients suffering from chronic alcoholic pancreatitis (18 calcified) were entered into a study of exocrine and endocrine pancreatic function based on two maximal stimulation tests, namely the secretin-cerulein test and the glucagon test with serum assays of C peptide. The glucagon test was also performed in 19 control subjects. In addition, 10 chronic pancreatitis patients and nine controls were subjected to an oral glucose tolerance test (OGTT) with serum insulin determinations. C peptide basal values were decreased only in patients with severe pancreatic exocrine insufficiency (P less than 0.001), while delta C peptide values were also reduced in patients with moderate exocrine insufficiency (P less than 0.001). Lipase output correlated very well with delta C peptide values (P less than 0.001). While serum insulin levels during OGTT and C peptide basal values showed no significant differences between the chronic pancreatitis and control groups, delta C peptide values were significantly reduced in chronic pancreatitis patients (P less than 0.02). Both endocrine and exocrine function are impaired in chronic pancreatitis, as demonstrated by maximal tests, even in early stages of the disease. PMID:1728534

    Detection of diffusely and irregularly dilated side branches of pancreatic ducts is a reliable criterion for the diagnosis of chronic pancreatitis (Japan Pancreas Society, revised 1995). This review deals with our experience with the utility of Magnetic resonance cholangiopancreatography (MRCP) in detecting this type of ductal abnormalities. Seventy patients with symptoms indicative of pancreatic or biliary diseases were evaluated using both MRCP and endoscopic retrograde chlangiopancreatography (ERCP) within an interval of three months or shorter. Using a 1.5 T unit, a multi-angle oblique multi-slab MRCP using a single-shot fast-spin-echo sequence was used to capture the pancreatic ducts. In 36 patients, MRCP was performed after administration of Gd-DTPA. The MRCP images were blindly and separately evaluated by two radiologists by counting the number of irregularly dilated side-branches in each segment. Two gastroenterologists in consensus evaluated the ERCP images as a standard of reference. The sensitivity, specificity and Az values for MRCP in the diagnosis of chronic pancreatitis were 0.33-0.50, 0.71-0.88 and 0.67-0.79 respectively without Gd-DTPA and 0.50-0.75, 0.78-0.93 and 0.82-0.89 with Gd-DTPA. Multi-angle oblique slab MRCP can be used for diagnosis of chronic pancreatitis with acceptable diagnostic accuracy when it is performed with intravenously administered of Gd chelates. (author)

    We systematically reviewed the clinical trials which recruited antioxidants in the therapy of pancreatitis and evaluated whether antioxidants improve the outcome of patients with pancreatitis. Electronic bibliographic databases were searched for any studies which investigated the use of antioxidants in the management of acute pancreatitis (AP) or chronic pancreatitis (CP) and in the prevention of post-endoscopic retrograde cholangio-pancreatography (post-ERCP) pancreatitis (PEP) up to February 2009. Twenty-two randomized, placebo-controlled, clinical trials met our criteria and were included in the review. Except for a cocktail of antioxidants which showed improvement in outcomes in three different clinical trials, the results of the administration of other antioxidants in both AP and CP clinical trials were incongruent and heterogeneous. Furthermore, antioxidant therapy including allopurinol and N-acetylcysteine failed to prevent the onset of PEP in almost all trials. In conclusion, the present data do not support a benefit of antioxidant therapy alone or in combination with conventional therapy in the management of AP, CP or PEP. Further double blind, randomized, placebo-controlled clinical trials with large sample size need to be conducted.

    Full Text Available Dear Sir, Dr Wagner’s erudite comments in the present issue of JOP. J Pancreas (Online [1] further illuminate the complex interactions between micronutrient deficiency, electrophilic stress, and disrupted methionine homeostasis, that together seem to precipitate chronic pancreatitis by impairing the exocytosis of zymogen granules from pancreatic acinar cells [2, 3]. Dr Wagner’s studies and arguments [1] underline the essentiality of methyl moieties for exocytosis. They act directly (by carboxymethylating small G proteins in the apical membrane, and indirectly by incorporation into phosphatidylcholine for granule membrane-apical membrane fusion during the exocytosis process. Dietary methionine is the main source of methyl groups, delivered via its first metabolite Sadenosylmethionine (SAM. Dietary folic acid - in concert with vitamin B12 and ascorbic acid (bioactive fraction of vitamin C - facilitates methionine regeneration from homocysteine. Dietary betaine and choline provide pre-formed methyl groups. The ancillary methyl sources (folic acid, betaine, choline could determine whether or not exocytosis can proceed when methionine intake falls short of need, as it does (along with insufficiency of vitamin C in chronic pancreatitis wherein demand increases due to cytochrome P450 induction [4], with increased release of reactive oxygen and xenobiotic species [2]. The vulnerability to the ensuing electrophilic stress of enzymes such as that which catalyses the conversion of methionine to SAM [5] rationalizes both the surge in circulating level of methionine and SAM in an acute exacerbation of chronic pancreatitis [6, 7], and evidence that the methionine metabolic pathway remains fractured thereafter [8]. A supplement of methionine (or SAM plus vitamin C curbs attacks, and additional choline (theoretically betaine alternatively [1] is helpful when treatment fails [2]. All these observations indicate the clinical relevance of methionine plus

    Full Text Available A 3-year-and-9-months old male neutered Bichon Frise was presented for a second opinion for diabetes mellitus, weight loss, pruritus, and loss of hair. During further work-up, the dog was diagnosed with uncontrolled diabetes mellitus and concurrent diagnoses of pancreatitis and atopy were also suspected. Multiple adjustments of insulin therapy did not improve control of diabetes mellitus. Also, a variety of different treatments failed to improve pruritus. The dog was seen by a veterinary dermatologist who further suspected atopy and started treatment with cyclosporine. Pruritus improved and coincidentally serum Spec cPL and fructosamine concentrations normalized after therapy, suggesting the possibility that cyclosporine may have controlled pancreatic inflammation and improved control of diabetes mellitus. This case report would suggest that further research into autoimmunity in dogs with chronic pancreatitis is warranted. Also, a controlled study is needed and in progress before the use of cyclosporine in dogs with chronic pancreatitis or a subgroup thereof can be advocated.

    A comparison of the diagnostic accuracy of ultrasound, computer tomography and ERPC in chronic or recurrent pancreatitis and pancreatic carcinoma has shown that ERPC is the most precise of the three methods. This was particularly important in the demonstration of the small, still operable, carcinomas of the pancreas. Sonography is most useful for serial observations of pancreatic pseudocyste due to chronic recurrent pancreatitis. In this situation, ERPC should only be used if sonography and computer tomography cannot localise the lesion. Where the computer tomogram has shown evidence of enlargement of the pancreas, sonography may show an area devoid of echoes within the enlarged organ, suggesting the presence of a carcinoma. Computer tomography is superior to ultrasonography in delineating the extent of extensive pancreatic disease and in showing the anatomical structures surrounding the pancreas.

    Full Text Available We deeply appreciate your publishing of our work - “Chronic metabolic acidosis destroys pancreas” in JOP (2014 [1]. We feel that our work can give the food for thought to many young researchers and health practitioners. A short review of our work may generate various questions and ideas for further investigations. In our work, we have focused on negative affects of the chronic metabolic acidosis on pancreatic function including: • Premature activation of the proteases within the pancreas • Diminishing the antimicrobial activity of the pancreatic juice • Suppressing of the flushing out zymogens from the pancreas • Precipitation of the aggressive bile acids • Calcification Authors believe that further research may provide more details of how the acidification destroys the pancreas and causes chronic pancreatitis. We would like to share some of our thoughts on this subject as follows: Descriptions of symptoms of chronic pancreatitis such as pain, malabsorption syndrome, steatorrhea, and weight loss are found in almost all medical books, textbooks, and articles. The medical literature refers to these conditions as “pancreatic insufficiency”. It is known that these symptoms occur when only 10 % of the exocrine pancreatic function is left intact. This is not an “insufficiency.” It is a pancreatic “failure” when the therapeutic opportunities are very limited.

    ática.The pancreas is a retroperitoneal organ that releases water, bicarbonate and digestive enzymes by the main pancreatic duct (MPD into the duodenum. Chronic pancreatitis (CP is typically caused, in adults, by chronic alcohol abuse and, less frequently hypertriglyceridemia, primary hyperparathyroidism or chystic fibrosis. Exocrine dysfunction results in malabsorption of fat and subsequent steatorrhea. Damage to pancreatic endocrine function is a late finding in CP and results in hyperglycaemia or overt diabetes mellitus. Care of patients with CP principally involves management of pain. A significant change in the pain pattern or the sudden onset of persistent symptoms suggests the need to rule out other potential etiologies, including peptic ulcer disease, biliary obstruction, pseudocysts, pancreatic carcinoma, and pancreatic duct stricture or stones, then is important to establish a secure diagnosis. Management of pain should then proceed in a judicious stepwise approach avoiding opioids dependence. Patients should be advised to stop alcohol intake. Fat malabsorption and other complications may also arise. Management of steatorrhea should begin with small meals and restriction in fat intake. Pancreatic enzyme supplements can relieve symptoms and reduce malabsorption in patients who do not respond to dietary restriction. Enzymes at high doses should be used with meals. Treatment with acid suppression to reduce inactivation of the enzymes from gastric acid are recommended. Supplementation with medium chain triglycerides and fat soluble vitamin replacement may be required. Management of other complications (such as pseudocysts, bile duct or duodenal obstruction, pancreatic ascites, splenic vein thrombosis and pseudoaneurysms often requires aggressive approach with the patient kept on total parenteral nutrition to minimize pancreatic stimulation.

  19. Contribution of double-labelling scintigraphy to the diagnosis of chronic pancreatitis (relative to 50 observations)

    International Nuclear Information System (INIS)

    This study, after a short anatomical and anatomo-pathological survey, outlines the main stages in the discovery of the pancreatic label and attempts to define the practical problems encountered in the application of scintigraphic methods. The choice of pancreatic indicator is shown to have been very difficult and the substance used, after much research, is still imperfect: Se75-labelled methionine. To offset the defects of this tracer some remarkable techniques have been developed, for example electronic subtraction to cut out the liver image. The equipment used is then described, together with the working procedure adopted at the Angers U.H.C. The results obtained on 50 observations are given in table form. In the discussion the following points are dealt with in turn: scintigraph interpretation criteria, the diagnostic contribution of scintigraphy, the place of this examination in the positive diagnosis of chronic pancreatitis. Examination of a limited number of observations leads to certain conclusions in agreement with those formulated by many authors. The scintigram is first and foremost a 'function of the active parenchyma mass'. According to LEGER it is limited by the fact that the scintigraph cannot distinguish between different pathological processes. Nevertheless this examination is considered to have real diagnostic value in pancreatic diseases, especially when all abnormal images exist

    The author presents his personal choice of practical relevant papers of pancreatic diseases from 2014 to 2015. Nutritional factors and hypertriglycidemia are discussed as causes of acute pancreatitis. Tools to avoid post-ERCP(endoscopic retrograde cholangiopancreatography) pancreatitis are described and the natural course of fluid collections and pseudocysts is demonstrated. The value of secretin-MRCP(magnetic resonance cholangiopancreatography) for diagnosis of chronic pancreatitis is illustrated. Data help to choose the minimally effective prednisolone dose in autoimmune pancreatitis. The increased prevalence of fractures in patients with chronic pancreatitis highlights the necessity of screening for bone density loss. The association of vitamin D intake with pancreatic cancer is described. The probability of cancer in IPNM is shown and innovative surgical concepts to reduce the loss of pancreatic function are presented. Finally neoadjuvant concepts for the treatment of pancreatic cancer are highlighted. PMID:27329710

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.

    Therapeutic vaccines to boost endogenous T-cell immunity rely on the stimulatory capacity of dendritic cells (DCs). The functionality of DCs in chronic hepatitis B virus (HBV) infection has been a long-standing debate. Therefore, we have attempted to summarize multiple studies investigating DC function in chronic HBV patients to determine whether common observations can be drawn. We found that the frequency and function of ex vivo-tested myeloid and plasmacytoid DCs were largely intact in patients with HBV infection and similar to those of healthy donor DCs. The main exception was reduced IFN-α production by plasmacytoid DC from chronic HBV patients. This reduced IFN-α production correlated with liver inflammation in multiple studies but not with viral load, suggesting that viral antigens have little effect on DC function. The majority of the confusion about DC function arises from studies reporting the reduced function of healthy donor DCs exposed to various sources of HBV in vitro. These direct effects of viral antigens are in contrast to data from HBV-infected patients. The variations in the assays used and areas that require further investigation are also covered.

    According to the important roles played by cytokines in induction of appropriate immune responses against hepatitis B virus(HBV),Dimitropoulou et al have examined the important cytokines in their patients.They showed that the serum levels of interleukin 10(IL-10)and interferon-γ(IFN-γ)were decreased in patients with HBeAg-negative chronic active hepatitis B compared with the inactive hepatitis B virus carriers(Dimitropoulou et al 2013).The controversy can be considered regarding the decreased serum levels of IFN-γin the HBeAg-negative chronic active hepatitis B patients.They concluded that subsequent to decreased expression of IFN-γ,the process of HBV proliferation led to liver diseases.Previous studies stated that HBV is not directly cytopathic for the infected hepatocytes and immune responses are the main reason for destruction of hepatocytes(Chisari et al,2010).Scientists believe that immune responses against HBV are stronger in active forms of chronic HBV infected patients than inactive forms(Zhang et al,2012).Therefore,the findings from Dimitropoulou et al may deserve further attention and discussion.Additionally,downregulation of IL-10 inchronically active hepatitis B infected patients has also confirmed our claim.IL-10 is an anti-inflammatory cytokine and its expression is increased in inactive forms in order to downregulate immune responses(Arababadi et al,2012).Thus,based on the results from Dimitropoulou et al,it can be concluded that increased immune responses in chronically active hepatitis B infected patients are related to declined expression of IL-10 and interestingly IFN-γis not involved in induction of immune responses in these patients.

    The aim of this study was to quantify pancreatic exocrine function in normal subjects and in patients with chronic pancreatitis (CP) before and after pancreatic duct drainage procedures (PDDP) with dynamic secretin-enhanced magnetic resonance (MR) cholangiopancreatography (S-MRCP). Pancreatic exocrine secretions [quantified by pancreatic flow output (PFO) and total excreted volume (TEV)] were quantified twice in ten healthy volunteers and before and after treatment in 20 CP patients (18 classified as severe, one as moderate, and one as mild according to the Cambridge classification). PFO and TEV were derived from a linear regression between MR-calculated volumes and time. In all subjects, pancreatic exocrine fluid volume initially increased linearly with time during secretin stimulation. In controls, the mean PFO and TEV were 6.8 ml/min and 97 ml; intra-individual deviations were 0.8 ml/min and 16 ml. In 10/20 patients with impaired exocrine secretions before treatment, a significant increase of PFO and TEV was observed after treatment (P<0.05); 3/20 patients presented post-procedural acute pancreatitis and a reduced PFO. The S-MRCP quantification method used in the present study is reproducible and provides normal values for PFO and TEV in the range of those obtained from previous published intubation studies. The initial results in CP patients have demonstrated non-invasively a significant short-term improvement of PFO and TEV after PDDP. (orig.)

    Full Text Available Pediatric chronic inflammatory demyelinating polyneuropathy (CIDP is an uncommon acquired disorder of unknown cause, presumed to have an immunological basis. We report 20 patients seen at Children′s Hospital Los Angeles over a period of 10 years. The outcome of our patients was favorable in a vast majority with good response to various treatments instituted. However, residual neurologic deficit was common. The choice of treatment modality was empirical and selected by the treating neurologist. Intravenous immunoglobulin (IVIG and corticosteroids were most commonly utilized for treatment. Plasmapheresis, mycophenolate mofetil, rituximab, cyclophosphamide, azathioprine, and abatacept were added if the patients were refractory to IVIG or became corticosteroid dependent. The spectrum of disease severity ranged from a single monophasic episode, to multiphasic with infrequent relapses with good response to IVIG, to progressive disease refractory to multiple therapies.

    Full Text Available Background. Patients with chronic pancreatitis (CP exhibit numerous risk factors for the development of small intestinal bacterial overgrowth (SIBO. Objective. To determine the prevalence of SIBO in patients with CP. Methods. Prospective, single-centre case-control study conducted between January and September 2013. Inclusion criteria were age 18 to 75 years and clinical and radiological diagnosis of CP. Exclusion criteria included history of gastric, pancreatic, or intestinal surgery or significant clinical gastroparesis. SIBO was detected using a standard lactulose breath test (LBT. A healthy control group also underwent LBT. Results. Thirty-one patients and 40 controls were included. The patient group was significantly older (53.8 versus 38.7 years; P < 0.01. The proportion of positive LBTs was significantly higher in CP patients (38.7 versus 2.5%: P < 0.01. A trend toward a higher proportion of positive LBTs in women compared with men was observed (66.6 versus 27.3%; P = 0.056. The subgroups with positive and negative LBTs were comparable in demographic and clinical characteristics, use of opiates, pancreatic enzymes replacement therapy (PERT, and severity of symptoms. Conclusion. The prevalence of SIBO detected using LBT was high among patients with CP. There was no association between clinical features and the risk for SIBO.

    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.

  13. Studies of the etiology of chronic pancreatitis with special reference to endoscopic manometry of sphincter of Oddi and quantitative cholescintigraphy

    International Nuclear Information System (INIS)

    This study was designed to elucidate the etiology of chronic pancreatitis. In a total of 23 patients with alcoholic (8) or idiopathic (18) pancreatitis, motor activity of the Oddi's sphincter was recorded by endoscopy to measure systolic pressure, diastolic pressure, motor cycle, the area surrounded by phasic waves and the base line for one minute (index A), and the area surrounded by phasic waves and the line connecting each bottom of the waves for one minute (index B). In addition, cholescintigraphy was performed in a total of 27 patients with alcoholic (4) or idiopathic (23) pancreatitis to obtain the time from appearance of common hepatic duct image to that of duodenal image (CD time). Systolic pressure (48.9±16.1 mmHg), diastolic pressure (33.9±14.3 mmHg), index A (10.4±3.2 cm2/min), and index B (3.1±0.9 cm2/min) were significantly higher than those in controls (28.3±8.3 mmHg, 19.5±7.6 mmHg, 6.1±1.7 cm2/min, and 1.7±0.9 cm2/min, respectively). Similarly. CD time was significantly longer for chronic pancreatitis than controls (44.1±22.4 min vs 18.5±17.3 min). In conclusion, chronic pancreatitis was associated with increased papillary resistance, resulting in retension of pancreatic juice. Papillary dysfunction has proved to be responsible for pathogenesis of chronic pancreatitis. (N.K.)

    AIM: To study the possible association between chronic pancreatitis (CP) and liver cirrhosis (LC) of alcoholic etiology, after excluding any other causes. METHODS: One hundred and forty consecutive alcoholic patients were subdivided into three groups: CP (η = 53), LC (η = 57), and asymptomatic alcoholic (n = 30). Clinical, biochemical and morphological characteristics, Child-Pugh index, indocyanine green test, and fecal pancreatic elastase-1 test were assessed. RESULTS: In patients with cirrhosis, major clinical manifestations of CP such as pancreatic pain and steatorrhea, as well as imaging alterations of CP such as calcifications, duct dilation and pseudocysts were absent; insulin-dependent diabetes was present in 5.3% of cases, and elastase-1 test was altered in only 7%, and severely altered in none. In patients with CP, clinical characteristics of cirrhosis such as ascites, encephalopathy and gastrointestinal hemorrhage were present in one case, Child-Pugh grade > A in 5.7%, and altered indocyanine green test in 1.9% cases. In asymptomatic alcoholism, there was only a non-coincident alteration of elastase-1 test and indocyanine test in 14.8% and 10%, respectively, but other characteristics of cirrhosis or CP were absent. An inverse correlation (r=-0.746) between elastase-1 test and indocyanine test was found in alcoholic patients. CONCLUSION: There is a scarce coincidence in clinical and morphological alterations among patients with CP or LC of alcoholic etiology, but an inverse correlation between pancreatic and liver function tests. These findings support that these alcoholic diseases evolve in a different manner and have different etiopathogenesis.

    To determine which abdominal CT findings predict severe fibrosis and post-operative pain relief in chronic pancreatitis (CP). Pre-operative abdominal CTs of 66 patients (mean age 52 ± 12 years, 53 % males) with painful CP who underwent the Whipple procedure (n = 32), Frey procedure (n = 32) or pancreatic head biopsy (n = 2), between 1/2003-3/2014, were evaluated. CT was evaluated for parenchymal calcifications, intraductal calculi, main pancreatic duct dilation (>5 mm), main pancreatic duct stricture, and abnormal side branch(es). The surgical histopathology was graded for fibrosis. CT findings were evaluated as predictors of severe fibrosis and post-operative pain relief using regression and area under receiver operating curve (AUC) analysis. Thirty-eight (58 %) patients had severe fibrosis. Parenchymal calcification(s) were an independent predictor of severe fibrosis (p = 0.03), and post-operative pain relief over a mean follow-up of 1-year (p = 0.04). Presence of >10 parenchymal calcifications had higher predictive accuracy for severe fibrosis than 1-10 parenchymal calcification(s) (AUC 0.88 vs. 0.59, p = 0.003). The predictive accuracy of >10 versus 1-10 parenchymal calcifications increased after adjusting for all other CT findings (AUC 0.89 vs. 0.63, p = 0.01). Parenchymal calcification(s) independently predict severe fibrosis and are significantly associated with post-operative pain relief in CP. The presence of >10 parenchymal calcifications is a better predictor of severe fibrosis than 1-10 parenchymal calcification(s). (orig.)

    2007-01-01

    Pain is a common symptom of pancreatic disease and is frequently difficult to manage. Pain relief provided by narcotics is often suboptimal and is associated with significant side effects. An alternative approach to pain management in pancreatic disease is the use of celiac plexus block (CPB) or neurolysis (CPN). Originally performed by anesthesiologists and radiologists via a posterior approach, recent advances in endoscopic ultrasonography (EUS) have made this technique an attractive alternative. EUS guided celiac plexus block/neurolysis is simple to perform and avoids serious complications such as paraplegia or pneumothorax that are associated with the posterior approach. EUS guided CPN should be considered first line therapy in patients with pain due to pancreatic cancer. It provides superior pain control compared to traditional management with narcotics. A trend for improved survival in pancreatic cancer patients treated with CPN has been reported,but larger studies are needed to confirm this finding.At this time, the use of EUS guided CPB cannot be recommended as routine therapy for pain in chronic pancreatitis since only one-half of the patients experience pain reduction and the beneficial effect tends to be short lived. EUS guided CPB and CPN should be used as part of a multidisciplinary team approach for pain management.

  18. Local Renin-Angiotensin System in the Pancreas: The Significance of Changes by Chronic Hypoxia and Acute Pancreatitis

    Directory of Open Access Journals (Sweden)

    Leung PS

    2001-01-01

    Full Text Available The circulating renin-angiotensin system (RAS plays an important role in the maintenance of blood pressure and fluid homeostasis. Recently, there has been a shift of emphasis from the circulating RAS to the local RAS in the regulation of individual tissue functions via a paracrine and/or autocrine mechanism. In fact, a local RAS has been proposed to be present in an array of tissues including the brain, heart, kidney and gonads. Our previous studies have provided solid evidence that several key elements of the RAS, notably angiotensinogen and renin, are present in the rat pancreas. The data support the existence of an intrinsic RAS in the pancreas and this local RAS may be important for the exocrine/endocrine functions of the pancreas. Interestingly, such a pancreatic RAS has been demonstrated to be markedly activated by experimental rat models of chronic hypoxia and acute pancreatitis. The activation of the pancreatic RAS by chronic hypoxia and experimental pancreatitis could play a role in the physiology and pathophysiology of the pancreas. The significant changes of pancreatic RAS may have clinical relevance to acute pancreatitis and hypoxia-induced injury in the pancreas.

    AIM: To determine the efficacy of Mac-2 binding protein (Mac-2bp) for diagnosis of chronic pancreatitis. METHODS: Fifty-nine healthy volunteers (HV), 162 patients with chronic pancreatitis (CP), and 94 patients with pancreatic ductal adenocarcinoma (PDAC) were enrolled in this study. We measured serum Mac-2bp using our developed enzyme-linked immunosorbent assay kit. Additional biochemical variables were measured using an automated analyzer (including aminotransferase, alanine aminotransferase, γ-glutamyltransferase, alkaline phosphatase, triglyceride, C-reactive protein, and amylase levels) or chemiluminescent enzyme immunoassay (carbohydrate antigen 19-9 and carcinoembryonic antigen). The ability of Mac-2bp to predict CP diagnosis accurately was assessed using receiver operating characteristic (ROC) analyses. RESULTS: Serum Mac-2bp levels were significantly increased in CP patients compared to HV (P < 0.0001) and PDAC patients (P < 0.0001). Area under the ROC curve values of Mac-2bp for the discrimination of CP from HV and PDAC were 0.727 and 0.784, respectively. Multivariate analyses demonstrated that serum Mac-2bp levels were independent determinants for CP diagnosis from HV and PDAC patients. Immunohistological staining showed that Mac-2bp was expressed faintly in the pancreas tissues of both CP and PDAC patients. Serum aspartate aminotransferase, alanine aminotransferase, γ-glutamyltransferase, alkaline phosphatase, and triglyceride levels were significantly higher in patients with CP or PDAC. Serum Mac-2bp levels were highly correlated with protein levels of alanine aminotransferase, γ-glutamyltransferase, and C-reactive protein, but not amylase, suggesting that the damaged liver produces Mac-2bp. CONCLUSION: Measurement of serum Mac-2bp may be a novel and useful biomarker for CP diagnosis as well as liver fibrosis in the general population. PMID:27158210

    AIM: To prove the hypothesis that patients with chronic pancreatitis would show increased theta activity during painful visceral stimulation.METHODS: Eight patients and 12 healthy controls underwent an experiment where the esophagus was electrically stimulated at the pain threshold using a nasal endoscope. The electroencephalogram (EEG) was recorded from 64 surface electrodes and "topographic matching pursuit" was used to extract the EEG information in the early brain activation after stimulation.RESULTS: A major difference between controls and patients were seen in delta and theta bands, whereas there were only minor differences in other frequency bands. In the theta band, the patients showed higher activity than controls persisting throughout the 450 ms of analysis with synchronous brain activation between the channels. The main theta components oscillated with 4.4Hz in the patients and 5.5Hz in the controls. The energy in the delta (0.5-3.5Hz) band was higher in the controls, whereas the patients only showed scattered activity in this band.CONCLUSION: The differences in the theta band indicate that neuropathic pain mechanisms are involved in chronic pancreatitis. This has important implications for the understanding and treatment of pain in these patients, which should be directed against drugs with effects on neuropathic pain disorders.

    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. We herein report the case of a 70-year-old man in whom pancreatic ad...

    CONCLUSION: We could demonstrate for the first time that an improvement in median overall survival with gemcitabine is significantly abolished by a persistent mild chronic pancreatitis and a systemic inflammatory response syndrome. In particular, the inflammation biomarkers C-reactive protein, IL-6, and IL-1α could indicate the prognostic benefit of gemcitabine chemotherapy and should now be tested in prospective patient-controlled trials.

    Full Text Available Context Chronic abdominal pain is the most difficult management issue in patients with chronic pancreatitis. Recently, a long-acting depo-formulated version of octreotide has been developed that can be given as a once monthly intramuscular injection, Octreotide LAR® (O-LAR rather than as a thrice daily subcutaneous injection (octreotide short-acting, O-SA. Objective To see if O-LAR is similar in efficacy to O-SA in the treatment of painful chronic pancreatitis in a small open-label, unblinded pilot study. Patients Seven advanced chronic pancreatitis patients with daily, severe abdominal pain who had previously responded to O-SA were recruited from the pancreas clinics of the University of Florida and monitored for one month on O-SA and for four months while on O-LAR. Each patient served as his/her own control as this was a paired data set. Main outcome measures 1 Daily VAS scores; 2 daily morphine equivalents; 3 monthly health related quality of life chronic pancreatitis surveys; 4 daily diaries of work/pleasurable activities missed or hospitalization/Emergency Department visits. Results Average daily VAS scores for patients during O-SA therapy were 4.50±2.28 and during the fourth month of O-LAR therapy, 3.86±2.11, difference -0.64±0.80 (P=0.078. Average daily morphine equivalents were not dissimilar at 124.3±177.3 mg during O-SA therapy and 131.6±194.3 mg during O-LAR therapy; difference 7.3±17.5 mg P=0.310. Health related quality of life chronic pancreatitis scores were not significantly changed when moving from O-SA to O-LAR. Adverse events were rare. Conclusions Octreotide LAR® may be a reasonable substitute for tid octreotide in treating chronic pancreatitis pain. Further, larger studies would be useful to better characterize the role of Octreotide LAR® in the management of chronic pancreatitis pain.

    Full Text Available Background: The usefulness of the typical direct methods involving duodenal intubation, such as the secretin and secretin–cholecystokinin tests, in the diagnosis of exocrine pancreatic dysfunction is widely accepted. However, these diagnostic tests tend to be avoided because of their technical complexity and the burden on patients. Recently, a simple breath test was developed for assessment of exocrine pancreatic function employing 13C-dipeptide [i.e., benzoyl-L-tyrosyl-[1-13C] alanine (Bz-Tyr-Ala]. Although alcohol abuse causes pancreatic damage in humans, this has been unclear in rats. Aims: The aim of the study is to evaluate the effect of ethanol exposure beginning at an early age on extra-pancreatic secretory function in rats. Materials and Methods: Twelve female rats of the F344 strain aged 12 months were used. Seven rats were fed on a commercial mash food with 16% ethanol solution (Japanese Sake as drinking-fluid since at 29 days of age (ethanol group. The remaining five rats were fed on a nutrient-matched isocaloric diet with water as drinking-fluid (control group. After 24-hr fasting, rats are orally administrated 1cc of water containing sodium 13C-dipeptide (5 mg/kg and housed in an animal chamber. The expired air in the chamber is collected in a breath-sampling bag using a tube and aspiration pump. The 13CO2 concentration is measured using an infrared spectrometer at 10-min interval for 120 min and expressed as delta per mil. Results: The breath 13CO2 level increased and peaked at 20 min in both two groups. In general, 13CO2 excretion peaked rapidly and also decreased sooner in ethanol rats than in control rats. The mean value of the maximal 13CO2 excretion is 34.7 per mil in ethanol rats, greater than in control rats (31.4 per mil, but the difference did not reach the statistically significance. Conclusion: Chronic ethanol feeding beginning at an early age does not affect extra-pancreatic secretory function in rats.

    Inonotus obliquus polysaccharide (IOP) was extracted by water with a yield of 9.83% and purified by an anion-exchange DEAE cellulose column and Sephadex G-200 gel with a polysaccharide content of 98.6%. The scavenging activities for 2,2-diphenyl-1-picryl-hydrazyl (DPPH) and hydroxyl radicals of IOP were 82.3% and 81.3% respectively at a concentration of 5 mg/mL. IOP was composed of Man, Rha, Glu, Gal, Xyl and Ara in a molar ratio of 9.81:3.6:29.1:20.5:21.6:5.4 respectively. The gel permeation chromatography indicated that IOP was a homogeneous polysaccharide with molecular weight of 32.5 kDa. IOP helped to alleviate pancreatic acinar atrophy and weight loss for chronic pancreatitis (CP) mice induced by Diethyldithiocarbamate (DDC). The SOD level was increased most by IOP-H treatment (400 mg/kg body weight). MDA, IL-1β and LDH were significantly decreased by IOP treatment, especially hydroxyproline, IFN-γ and AMS levels were decreased 39.18%, 37.82% and 41.57% by IOP-H treatment respectively compared to MC group. In conclusion, IOP possessed strong antioxidant activity for scavenging free radicals in vitro and vivo which could be propitious to CP therapy in mice. PMID:26955745

    Introduction Chronic pancreatitis (CP) can be a cause of recurrent, severe, disabling abdominal pain in children. Surgery has been suggested as a useful therapy, although experience is limited and the results unpredictable. We reviewed our experience of a two-stage protocol-preliminary endoscopic retrograde cholangiopancreatography (ERCP) and duct stenting, and if symptoms resolved, definitive surgical decompression by longitudinal pancreatojejunostomy (LPJ) (Puestow operation). Patients and Methods This is a single-center, retrospective review of children with established CP who underwent an LPJ between February 2002 and September 2012. A questionnaire was completed (incorporating visual analog scale pain and lifestyle scores) to assess functional outcome. Data are expressed as median (range). Results In this study, eight (M:F ratio of 4:4) children underwent an LPJ and one female child had a more limited pancreatojejunostomy anastomosis following preliminary ERCP and stent placement where possible. Diagnoses included hereditary pancreatitis (n = 3), idiopathic or structural pancreatitis (n = 5), and duct stricture following radiotherapy (n = 1). Median duct diameter presurgery was 5 (4-11) mm. Endoscopic placement of a Zimmon pancreatic stent was possible in six with relief of symptoms in all. Median age at definitive surgery was 11 (range, 7-17) years with a median postoperative stay of 9 (range, 7-12) days and a follow-up of 6 (range, 0.5-12) years. All children reported markedly reduced episodes of pain postprocedure. One developed diabetes mellitus, while three had exocrine deficiency (fecal elastase < 200 µg/g) requiring enzyme supplementation. The child with limited LPJ had symptomatic recurrence and required restenting and further surgery to widen the anastomosis to become pain free. Conclusion ERCP and stenting provide a therapeutic trial to assess possible benefit of a definitive duct drainage procedure. LPJ-the modified Puestow

    Chronic pancreatitis is a progressive fibroinflammatory disease with sustained damage of structure and function of pancreatic tissue, which results from a complex mix of causes (eg, alcohol, Biliary diseases), and often exists with intraductal calculi. Pain in the form of recurrent attacks of pancreatitis or constant and disabling pain is usually the main symptom. Steatorrhoea, diabetes, local complications associated with the disease are additional therapeuticchallenges. Combined with a variety of imaging methods such as BUS, CT, ERCP and MRCP, etc. Can significantly improve the diagnosis of chronic pancreatitis with pancreatic duct stone. Chronic pancreatitis with pancreatic duct stones should be actively treated, of which the focus is to control symptoms, improve function and treatment of complications with individual therapy. The appropriate surgery should be performed as soon as possible according to distribution of stone when the stone removal is not complete or recrudescent after extracorporeal shock wave lithotripsy and endoscopic. Completely removing the lesion, taking out all the stones, removing the pancreas and bile duct obstruction, fully drainage of pancreatic juice and trying to save the pancreatic tissues are the goal of the surgery, which can significantly improve quality of life of patients.%慢性胰腺炎是由于多种原因(酗酒、胆道系统疾病等)造成的胰腺组织结构和功能持续性损害,常合并胰管结石.疼痛是其最主要症状,同时常伴有消化不良、脂肪泻、糖尿病等并发症.结合多种影像学检查方法如B超、CT、ERCP和磁共振胰胆管造影(MRCP)等能明显提高慢性胰腺炎合并胰管结石的确诊率.慢性胰腺炎合并胰管结石应子以积极治疗,以控制症状、改善胰腺功能和治疗并发症为重点,强调以个体化治疗为原则的综合治疗.在体外震波碎石及内镜取石不彻底而症状不能控制或结石复发者应尽早手术治疗,根据结

    Chronic pancreatitis (CP) is a progressive inflammation of pancreas characterized by irreversible morphologic change and dysfunction. Patients with chronic pancreatitis often present with abdominal pain, diarrhoea, jaundice, weight loss and the development of diabetes. Polysaccharides of Ganoderma lucidum strain S3 (GLPS3) possess antioxidative and immunomodulatory activities. This study was to characterize chemical structures of GLPS3 and determine their effects on diethyldithiocarbamate (DDC)-induced CP in mice. The total sugar content of GLPS3 from fermentation broth (GLPS3-Ⅰ), cultured mycelia (GLPS3-Ⅱ) and fruiting body (GLPS3-Ⅲ) was 90.4%, 92.2% and 91.8% respectively. GLPS3-Ⅰ, GLPS3-Ⅱ and GLPS3-Ⅲ were composed of Glu:Gal:Ara:Xyl, Glu:Gal:Ara:Xyl:Man:Rha, and Glu:Gal:Xyl:Man:Rha:Fuc, with molar ratio of 2.82: 1.33: 1.26: 0.87, 5.84: 2.23: 0.72:1.38: 1.40: 0.51 and 5.34: 2.72: 1.14: 1.10: 0.33: 0.38, respectively. The antioxidative activity of GLPS3-Ⅱfrom cultured mycelia in vitro is higher than other two polysaccharides. The superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) in serum were increased while the malondialdehyde (MDA) levels were reversely decreased by GLPS3 treatment. Serum amylase (AMS) and lactic dehydrogenase (LDH) changes indicated the therapeutic effects of GLPS3. Moreover, interleukin-1beta (IL-1β) and interferon-gamma (INF-γ) contents were reduced most by GLPS3-Ⅱ. The results revealed that GLPS3 especially GLPS3-Ⅱfrom cultured mycelia were effective for CP therapy and bioactivity difference might be attributed to monosaccharide composition. PMID:26826268

    Full Text Available Background and objective: No nation-wide epidemiological study on the incidence and prevalence of chronic pancreatitis (CP had been thus far carried out in Spain. Our goal is to estimate the prevalence and incidence of CP, as well as to determine the diagnostic and therapeutic criteria used in Spanish pancreas units. Methods: An observarional, descriptive study of hospital pancreas units in Spain. CP-related epidemiology, etiology, manifestations, diagnostic tests, functional complications, and treatments were all assessed using a structured questionnaire. Overall results were estimated by weighting cases in each site. Results: Information was collected from six pancreas units with a sample frame of 1,900,751 inhabitants. Overall prevalence was 49.3 cases per 10(5 population (95 % CI, 46 to 52 and incidence was 5.5 cases per 10(5 inhabitant-years (95 % CI, 5.4 to 5.6. Most common etiologies included tobacco and alcoholism, which were associated with three in every four cases. The most prevalent symptoms were recurring pain (48.8 % and chronic abdominal pain (30.6 %. The most widely used diagnostic method was echoendoscopy (79.8 %, CT (computerized tomography (58.7 %, and MRI (magnetic resonance imaging/MRCP (magnetic resonance cholangiopancreatography (55.9 %. Most prevalent morphologic findings included calcifications (35 % and pseudocysts (27 %. Exocrine (38.8 % and endocrine (35.2 % pancreatic insufficiency had both a similar frequency. Treatments used were rather heterogeneous among sites, with enzyme replacement therapy (40.7 % and insulin (30.9 % being most commonly used. Conclusions: Pancreas units amass a significant number of both prevalent and incident CP cases. Patients seen in these units share a similar typology, and differences between units are greater regarding diagnostic and therapeutic strategies.

    International Nuclear Information System (INIS)

    A retrospective analysis of ultrasonograms of 24 patients with acute pancreatitis and 8 patients with chronic pancreatitis was performed. Nine cases were proven by surgery and 23 cases were diagnosed clinically. Generalized pancreatic enlargement with normal or decreased echogenecity was principal findings in acute pancreatitis, while pancreas was normal in size and echogenecity was normal or slightly altered in chronic pancreatitis. Ultrasonography is considered a simple and accurate method in the diagnosis of acute pancreatitis and thus it could be an initial test in patients with suspected acute pancreatitis

    We present a case of a 52-year old female patient with intermittent gastrointestinal bleeding and iron deficiency anaemia. Repeated endoscopic investigation revealed no diagnosis, but contrast-enhanced computed tomography showed a splenic artery pseudo-aneurysm secondary to chronic alcoholic pancreatitis. A distal pancreatectomy and splenectomy was performed. Hemosuccus pancreaticus is an uncommon cause of gastrointestinal bleeding, most frequently associated with chronic pancreatitis. Erosion of a peripancreatic artery by a pseudocyst can cause a pseudoaneurysm and rupture occurs in up to 10% of the cases. Bleeding from a pseudocyst wall or rupture of an atherosclerotic or traumatic aneurysm is rare. Angiography, contrast-enhanced computed tomography and endoscopic findings can be diagnostic in the majority of cases. Angiographic embolization or surgery are both therapeutic options depending on underlying nonvascular pancreas related indications requiring surgery. We discuss diagnostic pitfalls and current therapeutic strategies in the management of this disease. PMID:26712055

    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.

  3. Magnetic resonance imaging versus Acute Physiology And Chronic Healthy Evaluation II score in predicting the severity of acute pancreatitis

    International Nuclear Information System (INIS)

    Objective: To study the correlation between established magnetic resonance (MR) imaging criteria of disease severity in acute pancreatitis and the Acute Physiology And Chronic Healthy Evaluation II (APACHE II) score, and to assess the utility of each prognostic indicators in acute pancreatitis. Materials and methods: In this study there were 94 patients with acute pancreatitis (AP), all had abdominal MR imaging. MR findings were categorized into edematous and necrotizing AP and graded according to the MR severity index (MRSI). The APACHE II score was calculated within 24 h of admission, and local complications, death, duration of hospitalization and ICU were recorded. Statistical analysis was performed to determine their correlation. Results: In patients with pancreatitis, no significant correlation can be found between the APACHE II score and the MRSI score (P = 0.196). The MRSI score correlated well with morbidity (P = 0.006) but not with mortality (P = 0.137). The APACHE II score correlated well with mortality (P = 0.002) but not with the morbidity (P = 0.112). The MRSI score was superior to the APACHE II score as a predictor of the length of hospitalization (r = 0.52 vs. r = 0.35). A high MRSI and APACHE II score correlated with the need for being in the intensive care unit (ICU) (P = 0.000 and P = 0.000, respectively). Conclusion: In patients with pancreatitis, MRSI is superior to APACHE II in assessing local complications from pancreatitis but has a limited role in determining systemic complications in which the APACHE II score excels.

    Background Psoriasis is a chronic systemic inflammatory disorder, and studies have revealed its association with a variety of comorbidities. However, the risk of chronic pancreatitis (CP) in psoriasis has not been studied. This study aimed to investigate the risk of CP among patients with psoriasis. Methods Using the Taiwan National Health Insurance Research Database, this population-based cohort study enrolled 48430 patients with psoriasis and 193720 subjects without psoriasis. Stratified Cox proportional hazards models were used to compare the risks of CP between the patients with and without psoriasis. Results The incidence of CP was 0.61 per 1000 person-years in patients with psoriasis and 0.34 per 1000 person-years in controls during a mean 6.6-year follow-up period. Before adjustment, patients with psoriasis had a significantly higher risk of CP (crude hazard ratio (HR) = 1.81; 95% confidence interval (CI) = 1.53–2.15), and the risk remained significantly higher after adjustments for gender, age group, medications, and comorbidities (adjusted HR (aHR) = 1.76; 95% CI = 1.47–2.10). All psoriasis patient subgroups other than those with arthritis, including those with mild and severe psoriasis and those without arthritis, had significantly increased aHRs for CP, and the risk increased with increasing psoriasis severity. Psoriasis patients taking nonsteroidal anti-inflammatory drugs (aHR = 0.33; 95% CI = 0.22–0.49) and methotrexate (aHR = 0.28; 95% CI = 0.12–0.64) had a lower risk of developing CP after adjustments. Conclusions Psoriasis is associated with a significantly increased risk of CP. The results of our study call for more research to provide additional insight into the relationship between psoriasis and CP. PMID:27467265

    We report a 14-months-old infant who had obstructive jaundice caused by idiopathic fibrosing pancreatitis. Ultrasonography and abdominal computed tomography showed dilatation of the intrahepatic ducts, common bile duct, and the pancreatic duct. Diffuse swelling of the pancreas was also noted on CT. At laparotomy, the head portion of the pancreas revealed a stony hard consistency, and proliferation of fibrotic tissue was confirmed pathologically. Idiopathic fibrosing pancreatitis is a very rare disease entity in childhood, but should be considered in the differential diagnosis of obstructive jaundice in children who demonstrate bile duct and pancreatic duct dilatation and/or diffuse pancreas swelling.

    2006-11-01

    Endoscopic pancreatic sphincterotomy (EPS) has fallen into disuse for some time because of the risk of severe complications. More recently, EPS has been advocated as an effective treatment modality for several pancreatic disorders, including severe chronic pancreatitis, pancreatic pseudocyst, ampulloma, pancreas divisum, and pancreatic sphincter dysfunction. Favorable outcomes in patients undergoing EPS to facilitate further interventions, in whom long-term follow-up was available, was 70%; complications occurred in 14% and reintervention was required in 23%. The results were as good as those of surgery after long-term follow-up. Patients who underwent some form of pancreatic drainage after sphincterotomy had fewer complications (p = 0.03). Approximately 75% of patients with pancreas divisum who presented with idiopathic acute recurrent pancreatitis improved after endoscopic therapy, but only 25% of patients experienced pain reduction of at least 50%. The National Institutes of Health Consensus recommends EPS in patients with type I sphincter of Oddi dysfunction (SOD). In patients with type II SOD, prior manometry should be performed. In our series of 17 patients, we obtained results similar to those of other studies, although the number of patients was small. EPS appears to be a safe and effective technique, but further, well-designed, multicenter, prospective and long-term studies are required to evaluate these results and settle current controversies.

    Full Text Available Abstract Background The glycoprotein MFG-E8 mediates phagocytic clearance of apoptotic cells and influences the pathogenesis and progression of inflammatory diseases. MFG-E8 was shown to attenuate the progression of inflammation and to improve survival in septic rats. Accumulating evidence suggests an immunomodulatory link between MFG-E8 and the pro-inflammatory chemokine fractalkine, which may determine the severity of pain, fibrosis, and inflammation in chronic pancreatitis (CP. Methods The expression and localization of MFG-E8 was investigated in CP (n = 62, and normal pancreas (NP; n = 34 by QRT-PCR, Western-blot and immunohistochemistry analyses. Results were correlated with mRNA expression of fractalkine, CX3CR1, and with the presence and degree of pain and fibrosis. Human pancreatic stellate cells (hPSCs were isolated from CP tissues and evaluated for MFG-E8 mRNA expression after fractalkine stimulation. Results MFG-E8-mRNA was significantly overexpressed in CP and isolated hPSCs when compared to NP. Western-blot and immunohistochemistry analysis confirmed accumulation of MFG-E8 in CP, with noticeably increased MFG-E8 immunoreactivity in tubular complexes. MFG-E8 expression correlated significantly with fractalkine expression, severe fibrosis, and the presence of pain in CP patients. Stimulation of hPSCs with fractalkine led to a significant increase in MFG-E8 expression. Conclusions In the present study, we demonstrated for the first time that MFG-E8 is significantly up-regulated in CP patients and together with fractalkine correlated noticeably with severe fibrosis and the presence of pain. hPSCs overexpress MFG-E8 upon fractalkine stimulation in vitro, which underlines the suggested immunmodulatory link in CP and may be a key mechanism in CP fibrogenesis and pain generation. Taken together, these novel findings suggest that MFG-E8 blockade may be a promising tool for future immunotherapy in CP to attenuate both fibrosis and

    Mutation of Kirsten rat sarcoma viral oncogene homolog (KRAS) and chronic pancreatitis are the most common pathogenic events involved in human pancreatic carcinogenesis. In the process of long-standing chronic inflammation, aberrant metabolites of arachidonic acid play a crucial role in promoting carcinogenesis, in which the soluble epoxide hydrolase (sEH), as a pro-inflammatory enzyme, generally inactivates anti-inflammatory epoxyeicosatrienoic acids (EETs). Herein, we determined the effect of our newly-synthesized novel compound trans-4-{4-[3-(4-chloro-3-trifluoromethyl-phenyl)-ureido]-cyclohexyloxy}-pyridine-2-carboxylic acid methylamide (t-CUPM), a dual inhibitor of sEH and RAF1 proto-oncogene serine/threonine kinase (c-RAF), on inhibiting the development of pancreatitis and pancreatic intraepithelial neoplasia (mPanIN) in LSL-Kras(G12D)/Pdx1-Cre mice. The results showed that t-CUPM significantly reduced the severity of chronic pancreatitis, as measured by the extent of acini loss, inflammatory cell infiltration and stromal fibrosis. The progression of low-grade mPanIN I to high-grade mPanIN II/III was significantly suppressed. Inhibition of mutant Kras-transmitted phosphorylation of mitogen-activated protein kinase's kinase/extracellular signal-regulated kinases was demonstrated in pancreatic tissues by western blots. Quantitative real-time polymerase chain reaction analysis revealed that t-CUPM treatment significantly reduced the levels of inflammatory cytokines including tumor necrosis facor-α, monocyte chemoattractant protein-1, as well as vascular adhesion molecule-1, and the levels of Sonic hedgehog and Gli transcription factor (Hedgehog pathway). Analysis of the eicosanoid profile revealed a significant increase of the EETs/dihydroxyeicosatrienoic acids ratio, which further confirmed sEH inhibition by t-CUPM. These results indicate that simultaneous inhibition of sEH and c-RAF by t-CUPM is important in preventing chronic pancreatitis and carcinogenesis

    Objective To evaluate the clinical characteristics of and outcome of various treatment modalities for chronic pancreatitis with pancreatic duct stones. Methods Thirty cases of chronic pancreatitis with pancreatic duct stones treated at the Xiqing Hospital and Tianjin Nankai Hospital were randomly selected from the medical records spanning March 2005 to November 2011 , and used for retrospective analysis. Results The most frequent causes of chronic pancreatitis with pancreatic duct stones were long - term alcohol abuse and biliary tract disease. Upper abdominal pain was the most commonly reported clinical manifestation. B ultrasound and computed tomography were the most frequently used diagnostic methods. Two patients underwent traditional surgery to remove pancreatic duel stones, and 18 patients received endoscopic therapy; all 20 cases of invasive intervention achieved satisfactory results. Conclusion Chronic pancreatitis with pancreatic duct stones lacks specificity of clinical symptoms, complicating diagnosis and treatment. Surgical intervention is an effective treatment measure. While the surgical approach, either traditional or endoscopic, should be assigned according to an individual' s condition, the less invasive endoscopic therapy may be advantageous for less severe cases of pancreatic duct stones.%目的 探讨慢性胰腺炎合并胰管结石临床特点及治疗方式.方法 我院及天津市南开医院2005年3月至2011年11月收治的慢性胰腺炎合并胰管结石患者30例进行回顾性分析.结果 长期酗酒和胆道疾病是慢性胰腺炎合并胰管结石的主要病因.上腹痛为最常见的临床表现.B超及CT为最常用的检查手段.2例胰管结石患者行手术治疗,18例胰管结石患者采用内镜治疗,效果满意.结论 慢性胰腺炎胰管结石的临床症状缺乏特异性,诊治比较复杂,目前手术仍然是最主要的手段,但应采取个体化手术方案.对于较局限的胰管结石,内镜治疗有其很大的优越性.

    AIM: Endoscopic metal stenting (EMS) offers good results in short to medium term follow-up for bile duct stenosis associated with chronic pancreatitis (CP);however, longer follow-up is needed to determine if EMS has the potential to become the treatment of first choice.METHODS: EMS was performed in eight patients with severe common bile duct stenosis due to CR After the resolution of cholestasis by endoscopic naso-biliary drainage three patients were subjected to EMS while,the other five underwent EMS following plastic tube stenting. The patients were followed up for more than5 years through periodical laboratory tests and imaging techniques.RESULTS: EMS was successfully performed in all the patients. Two patients died due to causes unrelated to the procedure: one with an acute myocardial infarction and the other with maxillary carcinoma at 2.8 and 5.5years after EMS, respectively. One patient died with cholangitis because of EMS clogging 3.6 years after EMS.None of these three patients had showed symptoms of cholestasis during the follow-up period. Two patients developed choledocholithiasis and two suffered from duodenal ulcers due to dislodgement of the stent between 4.8 and 7.3 years after stenting; however, they were successfully treated endoscopically. Thus, five of eight patients are alive at present after a mean follow-up period of 7.4 years.CONCLUSION: EMS is evidently one of the very promising treatment options for bile duct stenosis associated with CP, provided the patients are closely followed up; thus setting a system for their prompt management on emergency is desirable.

    Full Text Available Literature has been showing a tendency of reducing the limits of Whipple's resection. The main technical advance was the pylorus preserving resection, technique proposed by Traverso and Longmire in 1978. The pancreticoduodenectomy for chronic pancreatitis, is probably the best opportunity to apply this type of procedure. In these specific patients, the author preserved the pylorus and the third portion of the duodenum. The gastrointestinal transit was reconstructed by the duodenumduodenal anastomosis and the bile duct and the pancreas were drained in a Roux-en-way loop . Follow-up showed no important complication, with no problems related to gastric emptying and without pain.

  16. 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.)

  20. 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

    Endoscopic retrograde cholangiopancreaticography (ERCP) is the morphologic gold standard for the diagnosis of chronic pancreatitis. Magnetic Resonance Imaging (MRI) enables the visualization of not only the pancreatic duct but also the surrounding parenchyma using T2- and T1-weighted sequences before and after the application of a contrast agent. Moreover, it allows the depiction of ductal segments distal to a stenosis or occlusion. However, conventional Magnetic Resonance Cholangiopancreaticography (MRCP) was not able to achieve accuracy similar to that of ERCP. Despite many technological innovations, such as fast breath-hold acquisitions or respiratory-gated 3D sequences, this drawback could not be overcome. In recent years, secretin-enhanced MRCP has been used for the diagnosis of chronic pancreatitis. A recent study showed that secretin not only improves the visibility of the pancreatic duct and its side branches but it also enhances the diagnostic accuracy of MRCP. The sensitivity, specificity, and positive and negative predictive values were improved by the application of secretin. Moreover, the agreement between independent observers increased after the use of secretin. In addition, quantitative post-processing tools have been developed that enable the measurement of the exocrine pancreatic output non-invasively using secretin-enhanced MRCP. These tools facilitate applications, such as functional follow-up after pancreaticogastrostomy and pancreaticogastric anastomoses, evaluation of the functional status of the graft after pancreas transplantation and follow-up of pancreatic drainage procedures and duct disruption.

    Directory of Open Access Journals (Sweden)

    Jonas Rosendahl

    Full Text Available BACKGROUND: Chronic pancreatitis (CP is an inflammatory disease that in some patients leads to exocrine and endocrine dysfunction. In industrialized countries the most common aetiology is chronic alcohol abuse. Descriptions of associated genetic alterations in alcoholic CP are rare. However, a common PNPLA3 variant (p.I148M is associated with the development of alcoholic liver cirrhosis (ALC. Since, alcoholic CP and ALC share the same aetiology PNPLA3 variant (p.I148M possibly influences the development of alcoholic CP. METHODS: Using melting curve analysis we genotyped the variant in 1510 patients with pancreatitis or liver disease (961 German and Dutch alcoholic CP patients, 414 German patients with idiopathic or hereditary CP, and 135 patients with ALC. In addition, we included in total 2781 healthy controls in the study. RESULTS: The previously published overrepresentation of GG-genotype was replicated in our cohort of ALC (p-value <0.0001, OR 2.3, 95% CI 1.6-3.3. Distributions of genotype and allele frequencies of the p.I148M variant were comparable in patients with alcoholic CP, idiopathic and hereditary CP and in healthy controls. CONCLUSIONS: The absence of an association of PNPLA3 p.I148M with alcoholic CP seems not to point to a common pathway in the development of alcoholic CP and alcoholic liver cirrhosis.

    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.

  5. Pancreas divisum and duodenal diverticula as two causes of acute or chronic pancreatitis that should not be overlooked: a case report

    Directory of Open Access Journals (Sweden)

    De Filippo Massimo

    2008-05-01

    Full Text Available Abstract Introduction Pancreas divisum is a congenital anatomical anomaly characterized by the lack of fusion of the ventral and dorsal parts of the pancreas during the eighth week of fetal development. This condition is found in 5% to 14% of the general population. In pancreas divisum, the increased incidence of acute and chronic pancreatitis is caused by inadequate drainage of secretions from the body, tail and part of the pancreatic head through an orifice that is too small. The incidence of diverticula in the second part of the duodenum is found in approximately 20% of the population. Compression of the duodenal diverticula at the end of the common bile duct leads to the formation of biliary lithiasis (a principal cause of acute pancreatitis, pain associated with biliary lithiasis owing to compression of the common bile duct (at times with jaundice, and compression of the last part of Wirsung's duct or the hepatopancreatic ampulla (ampulla of Vater that may lead to both acute and chronic pancreatitis. Case presentation We describe the radiological findings of the case of a 75-year-old man with recurrent acute pancreatitis due to a combination of pancreas divisum and duodenal diverticula. Conclusion Magnetic resonance cholangiopancreatography is advisable in patients with recurrent pancreatitis (both acute and chronic since it is the most appropriate noninvasive treatment for the study of the pancreatic system (and the eventual presence of pancreas divisum and the biliary systems (eventual presence of biliary microlithiasis. Moreover, it can lead to the diagnostic suspicion of duodenal diverticula, which can be confirmed through duodenography with X-ray or computed tomography scan with a radio-opaque contrast agent administered orally.

    Full Text Available Chronic pancreatitis is a challenging disease; the constellation of chronic abdominal pain and metabolic derangements present unique difficulties to the treating physician. Initial treatment revolves around lifestyle modification, pain control, and management of exocrine insufficiency. In refractory cases, total pancreatectomy with islet cell auto transplantation (TP-IAT is an option for patients with diffuse disease not amenable to subtotal pancreatectomy or a decompressive (drainage operation. This procedure aspires to alleviate pain and avoid surgically induced brittle diabetes, a morbid complication of total pancreatectomy alone. Herein, we review the indications, optimal timing, surgical outcomes and controversies for TP-IAT, focusing on recently published reports.

  7. MRI versus acute physiology and chronic healthy evaluation Ⅲ score for the assessment of the severity of acute pancreatitis

    International Nuclear Information System (INIS)

    Objective: To study the severity of acute pancreatitis (AP) by using MRI and the acute physiology and chronic healthy evaluation Ⅲ (APACHE Ⅲ) score, and the correlation between corresponding MRI findings and APACHE Ⅲ scores. Methods: One hundred patients with AP undergoing abdominal MRI were recruited in the study. The MRI features of acute pancreatitis were recorded. The severity of AP on MRI was graded by MR severity index (MRSI) as mild (0 to 2 points), moderate (3 to 6 points) and severe (7 to 10 points). APACHE Ⅲ score was denoted for AP was as mild (< 35 points) and severe (≥ 35 points). The local and systematic complications,mortality, need to intense care unit (ICU), and hospitalization time were recorded and compared with MRSI and APACHE Ⅲ score. Nonparametric Spearman correlation was calculated for testing the correlation between the MRSI, the APACHE Ⅲ and hospitalization time. The correlation of clinical results with MRSI and APACHE Ⅲ was calculated by χ2 test. Results: In the 100 patients with AP,there were respectively 80 and 20 patients with edematous and necrotic pancreatitis on MRI. According to MRSI, 34, 59 and 7 patients had mild, moderate, and severe acute pancreatitis,respectively. The APACHE Ⅲ score was (24.9 ± 12.2) points. Seventy-seven patients had less than 35 points and 23 patients had more than 35 point of APACHE Ⅲ score. There were significant differences in the local complication, systematic complication, need to ICU among the three groups in MRSI score, respectively (χ2=9.161, 19.118, 54.767; P<0.01). There was difference in the systematic complication between mild and severe AP in APACHE Ⅲ score (χ2=13.120, P=0.000), but there were no differences (χ2=0.245, χ2=2.568; P>0.05) in the local complication,need to ICU between mild and severe AP in APACHE Ⅲ score. There was weak correlation (r=0.235, P=0.019) between MRSI score and hospitalization time,and no difference (r=0.168, 0.105; P>0.05) between APACHE

    Full Text Available Abstract Objective In general, chronic pancreatitis (CP primarily requires conservative treatment. The chronic pain syndrome and complications make patients seek surgical advice, frequently after years of progression. In the past, surgical procedures involving drainage as well as resection have been employed successfully. The present study compared the different surgical strategies. Patients and Methods From March 2000 until April 2005, a total of 51 patients underwent surgical treatment for CP at the Department of surgery, University of Schleswig-Holstein, Campus Lübeck. Out of those 51 patients, 39 (76.5% were operated according to the Frey procedure, and in 12 cases (23.5% the Whipple procedure was performed. Patient data were documented prospectively throughout the duration of the hospital stay. The evaluation of the postoperative pain score was carried out retrospectively with a validated questionnaire. Results Average operating time was 240 minutes for the Frey group and 411 minutes for the Whipple group. The medium number of blood transfusions was 1 in the Frey group and 4.5 in the Whipple group. Overall morbidity was 21% in the Frey group and 42% in the Whipple group. 30-day mortality was zero for all patients. During the median follow-up period of 50 months, an improvement in pain score was observed in 93% of the patients of the Frey group and 67% of the patients treated according to the Whipple procedure. Conclusion The results show that both the Frey procedure as well as partial pancreaticoduodenectomy are capable of improving chronic pain symptoms in CP. As far as later endocrine and exocrine pancreatic insufficiency is concerned, however, the extended drainage operation according to Frey proves to be advantageous compared to the traditional resection procedure by Whipple. Accordingly, the Frey procedure provides us with an organ-preserving surgical procedure which treats the complications of CP sufficiently, thus being an

  10. Endoscopic pancreatic duct stent placement for inflammatory pancreatic diseases

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    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.

    In this study, we investigated the free radical-mediated cytotoxic effects of chronic ethanol consumption on the pancreatic tissue and a possible cytoprotective effect of betaine as a methyl donor and an important participant in the methionine cycle. Twenty-four male Wistar rats were divided into control, ethanol, and ethanol+betaine groups. Prior to sacrifice, all groups were fed 60 mL/diet per day for two months. Rats in the ethanol group were fed with ethanol 8 g/kg/day. The ethanol+betaine groups were fed ethanol plus betaine (0.5 % w/v). Malondialdehyde levels and adenosine deaminase, superoxide dismutase, and xanthine oxidase activities were determined in pancreatic tissues of rats. Compared to control group, MDA levels increased significantly in the ethanol group (p<0.05). MDA levels in the ethanol+betaine group were significantly decreased compared to the ethanol group (p<0.05). ADA activity in the ethanol+betaine group decreased significantly when compared to the ethanol group (p<0.05). XO activities in ethanol-fed rats were decreased significantly compared to the control group (p<0.05). XO activity in the betaine group was increased significantly (p<0.05) compared to the ethanol group. SOD activity in the ethanol group decreased significantly compared to control group (p<0.001). SOD activity in the ethanol+betaine group decreased significantly (p<0.05) compared to the control group. We think that betaine, as a nutritional methylating agent, may be effective against ethanol-mediated oxidative stress in pancreatic tissue. PMID:20108209

Extensive studies indicate that capsaicin is a cancer-suppressing agent via blocking the activities of several signal transduction pathways including nuclear factor-kappaB, activator protein-1 and signal transducer and activator of transcription 3. However, there is little study on the effect of capsaicin on pancreatic carcinogenesis. In the present study, the effect of capsaicin on pancreatitis and pancreatic intraepitheli...

  13. A CONTROVERSIAL ON THE DIAGNOSIS OF CHRONIC BULLOUS TYPE MUCOCUTANEOUS DISEASE INVOLVING ORAL MUCOSA (A CASE REPORT

    Directory of Open Access Journals (Sweden)

    2006-04-01

    Full Text Available A case of chronic bullous type mucocutaneous disease involving oral mucosa was reported from a 56 years old man with never healing oral ulcers and wound on the perianal skin for three years. There were also red and black spots on the limb and back skin and a lesion on nail. Painful oral lesion consisted of mucous erosion, desquamative gingivitis, and sloughing area on palate and tongue. The patient is diabetic. The first perianal skin diagnosis was granulomatous candidasis with differential diagnosis pemphigus vegetates and acuminarum condiloma. However the histopathologic examination did not support these diagnosis. After several histopathologic examinations, the latest perianal skin diagnosis was lichen planus with differential diagnosis granulomatous vasculitis, bowenoid papulosis and pyodema gangrenosum. Other skin diagnosis was erythema multiforme. Oral diagnosis was mucous membrane pemphigoid with differential diagnosis lichen planus, Behçet's syndrome and erythema multiforme. Oral histopathologic examinations showed a sub-epithelial blister, which supported mucous membrane pemphigoid. A lip balm, prednisone 5 mg oral rinse and multivitamins were given but oral improvement started after blood sugar level was controlled. Conclusion: It is not yet known whether skin and oral mucous lesions are from the same disease or not.

    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.

    BACKGROUND: There is a growing evidence that matrix metalloproteinase (MMP)-2 and MMP-9 (gelatinases) play an important role in the pathogenesis of numerous disorders, especially with inflammatory etiology and extracellular matrix (ECM) remodeling. Despite the fact that gelatinases involve in liver cirrhosis is provided in the literature, their role in the pathogenesis of chronic pancreatitis and non-specific inflammatory bowel diseases is still under investigation. DATA SOURCES: We carried out a PubMed search of Englishlanguage articles relevant to the involvement of gelatinases in the pathogenesis of liver fibrosis, pancreatitis, and non-specific inflammatory bowel diseases. RESULTS: The decreased activity of gelatinases, especially MMP-2, is related to the development of liver fibrosis, probably due to the decrease of capability for ECM remodeling. Similar situation can be found in chronic pancreatitis; however, reports on this matter are rare. The presence of non-specific inflammatory bowel diseases results in MMP-9 activity elevation. CONCLUSION: The fluctuation of gelatinases activity during liver fibrosis, chronic pancreatitis and non-specific inflammatorybowel diseases is observed, but the exact role of these enzymes demands further studies.

  19. Evaluation of the biliary gallbladder emptying in patients with calcificant chronic pancreatitis through a scintilographic study with DISIDA Tc-99m

    International Nuclear Information System (INIS)

    The eventual relation between biliary lithiasis and chronic pancreatitis (CP) has been studied before but the research on the gallbladder involvement in chronic pancreatitis patients are rare, specially from a functional point of view. In order to study that, gallbladder emptying was evaluated in 11 patients with CP and the results were compared and analyzed statistically with the ones observed in 10 controls. This series exclude patients and controls who presented any kind of prior or current affection, or condition, that could interfere with the gastric or gallbladder emptying and the release of the entero pancreatic hormones. Gallbladder emptying was studied through the scintillographic method, using Tc-99m DISIDA, through the calculation of the ejection (EF) of the gallbladder (GB), at 30, 45 and 60 minutes. In the patients this evaluation was studied in two different periods of time with an interval of two to four weeks between them, without (CPWOP) and with (CPWP) the addition of pancreatic extract. The analyses of the results disclosed that the EF of GB at 60 minutes was significantly higher in the controls when compared tro chronic pancreatopaths. On the other hand, the EF of GB in these patients did not show any statistically significant differences after the administration of pancreatic extract. The results suggest that the delay in the gallbladder emptying does not depend exclusively on the eventual alteration in the intestinal phase of the gallbladder stimulation, but it probably also results from the association with other factors involved, as a mechanic factor, which depends on the compression of the main biliary tract through the chronic pathological process located in the cephalic portion of the pancreas.

    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

    2007-09-01

    Full Text Available Context Chronic pancreatitis is a continuous inflammatory disease of the pancreas resulting in scarring and fibrosis with consequent decline in exocrine and endocrine function. The inflammatory process leads to the development of a head mass, and strictures and stones in the pancreatic duct which present as pain, or loco regional complications such as duodenal obstruction and biliary obstruction. The gold standard for the treatment of pain and loco regional complications remains surgery, which is usually a combination of drainage and partial resection (coring. This can be hazardous due to adhesions, inflammation or portal hypertension. Case report We report a case in which severe bleeding from the pancreatic duct was encountered during a Frey procedure. It was from the superior mesenteric vein/splenic vein confluence and would have warranted a Whipple procedure. Conclusion We describe a pancreatotomy for exposure and control of the bleeding, with resuturing of the cut pancreas and completion of the pancreaticojejunostomy.

    Full Text Available Differential diagnosis of solid pancreatic lesions remains as an important clinical challenge, mainly for the differentiation between mass forming chronic pancreatitis, autoimmune pancreatitis and pancreatic adenocarcinoma. Endoscopic ultrasound (EUS, computed tomography (CT and magnetic resonance imaging (MRI can all provide valuable and complementary information in this setting. Among them, EUS has the unique ability to obtain specimens for histopathological diagnosis and can therefore play a crucial role in the evaluation patients with inconclusive findings on initial examinations. Nowadays, new developed techniques associated to EUS, like elastography and contrast enhancement, have shown promising results for the differential diagnosis of these pancreatic lesions.El diagnóstico diferencial de las lesiones sólidas pancreáticas permanece como un reto clínico importante, sobre todo para la diferenciación entre la masa de conformación pancreatitis crónica, pancreatitis autoinmune y el adenocarcinoma de páncreas. Ecografía endoscópica (USE, la tomografía computarizada (TC y la resonancia magnética (MRI pueden proporcionar información valiosa y complementaria en este entorno. Entre ellos, la USE tiene la capacidad única de obtener muestras para diagnóstico histopatológico y por lo tanto, puede desempeñar un papel crucial en la evaluación de los pacientes con resultados poco concluyentes en los exámenes iniciales. Hoy en día, las nuevas técnicas desarrolladas asociadas a la USE, como la elastografía y realce de contraste, han mostrado resultados prometedores para el diagnóstico diferencial de las lesiones pancreáticas.

  4. 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

    Objective To explore the treatments and their effects on painless chronic pancreatitis (CP) in adult. Methods A historical cohort study of adult subjects with CP, who were hospitalized in our center in the last decade, was performed, and the clinical data were analyzed. Results There were 56 cases of adult painless CP, and 46 (82.1%) (31 males and 15 females, age 51.6±14.5 years) were followed up(34.5±27.1 months). Imaging findings showed 26 cases of pancreatic duct stones and morphological changes. These patients received endoscopic intervention therapy(n=14), surgical procedures(n=7), combined endoscopic and surgical treatment(n=3) and conservative treatment(n=2). Another group of 18 cases of pancreatic or peripheral occupying lesions received surgery. During follow-up of the above 2 groups, 1 patient died of pancreatic cancer in each group. The symptoms of diabetes and diarrhea were not relieved, but there was improvement of general condition in some patients. Stones re-occurred after surgery in one patient. Two patients with pancreatic duct dilation and cysts underwent endoscopic treatment(n=1) and surgical procedure(n=1), respectively. But the latter patient experienced gastric bleeding, cirrhosis and jaundice with unknown reason after the surgery. Conclusion In adult patients with CP, endoscopic and surgical procedures had similar effect in patients with pancreatic duct stones and dilation. Surgical procedures are preferably performed in those with pancreatic occupying lesions. Further study is needed in those only with pancreatic duct dilation. The above treatments can improve general conditions in some patients. Intensive surveillance is suggested to the patients with painless CP.%目的 探究成人无腹痛慢性胰腺炎(CP)的治疗方法及其疗效.方法 总结近10年CP患者临床资料,分析成人无痛性CP患者治疗措施及疗效.结果 成人无痛性CP共56例,成功随访的46例(82.1%)中,男31例,女15例,年龄(51.6±14.5)

    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.

    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.

  10. Current Concepts and Diagnosis of IgG4-Related Pancreatitis (Type 1 AIP).

    Kawa, Shigeyuki

    2016-08-01

    Although now considered to be a member of the systemic entity of immunoglobulin G4- (IgG4-) related disease, IgG4-related pancreatitis is generally referred to as type 1 autoimmune pancreatitis (AIP). Type 1 AIP was established based on a pathological background of lymphoplasmacytic sclerosing pancreatitis, high serum IgG4 concentration, and abundant IgG4-bearing plasma cell infiltration. The characteristic clinical features of type 1 AIP, such as elderly male preponderance, obstructive jaundice, and mass-forming lesions in the pancreas, often mimic those of pancreatic cancer. However, because AIP responds favorably to corticosteroid treatment, careful differentiation from pancreatic cancer is required. An AIP diagnosis is currently based on the 2011 International Consensus Diagnostic Criteria for AIP, which are based on high sensitivity, selectivity, and accuracy. Over the long term, AIP can progress to a chronic condition, with pancreatic stone formation and atrophy resembling that of chronic pancreatitis. Although AIP has been linked to the complication of malignancies, it remains controversial whether an association exists between the disease and tumor formation. PMID:27466795

  11. Pancreatic changes in patients with primary sclerosing cholangitis: MR cholangiopancreatography and MRI findings

    International Nuclear Information System (INIS)

    Purpose: To evaluate the possible pancreatic changes and their frequencies in patients with primary sclerosing cholangitis (PSC) on MR cholangiopancreatography (MRCP), and conventional abdominal MRI. Materials and Methods: Patient group consisted of 29 PSC (13 male, 16 female) cases, whereas cohort 1 consisted of 12 female patients with primary biliary cirrhosis, and cohort 2 consisted of 17 patients (6 male, 11 female) with non-immune chronic liver disease. Two radiologists retrospectively evaluated the MR examinations paying special attention to the pancreatic size (atrophy or enlargement), T1- and T2-signal intensity of the pancreas, focal pancreatic lesion, capsule-like rim, peripancreatic edema or fluid, fascial thickening, and pancreatic ducts (dilatation or narrowing). The results are expressed as percentages. Three groups were compared using Pearson chi-square test for each feature. However, only p-value for 'dilatation of the pancreatic duct' was determined, whereas p-value could not be calculated because of the insufficient number of subjects/sequences for the other features. Results: Twelve PSC patients (41.3%) had pancreatic abnormalities. The most common pancreatic changes in PSC patients were decreased T1-signal intensity (44%) and dilatation of the pancreatic duct (13.8%), respectively. Increased T2-signal intensity was also shown in 2 PSC patients (6.9%). Conclusion: Even PSC patients without any sign of pancreatitis, can show MR changes in the pancreatic parenchyma or the pancreatic duct. The etiologies of these changes, and whether they are unique to PSC, are still controversial. Histopathological studies bringing light to these pancreatic changes are needed.

    Full Text Available The markedly high prevalence of obesity contributes to the increased incidence of chronic diseases, such as diabetes, hypertension, sleep apnea, and heart disease. Because of high prevalence of obesity in almost all countries, it has been the focus of many researches throughout the world during the recent decades. Along with increasing researches, new concepts and controversies have been emerged. The existing controversies on the topic are so deep that some researches argue on absolutely philosophical questions such as “Is obesity a disease?” or “Is it correct to treat obesity?” These questions are based on a few theories and real data that explain obesity as a biological adaptation and also the final results of weight loss programs. Many people attempt to lose weight by diet therapy, physical activity and lifestyle modifications. Importantly, weight loss strategies in the long term are ineffective and may have unintended consequences including decreasing energy expenditure, complicated appetite control, eating disorders, reducing self-esteem, increasing the plasma and tissue levels of persistent organic pollutants that promote metabolic complications, and consequently, higher risk of repeated cycles of weight loss and weight regain. In this review, major paradoxes and controversies on obesity including classic obesity paradox, pre-obesity; fat-but-fit theory, and healthy obesity are explained. In addition, the relevant strategies like “Health at Every Size” that emphasize on promotion of global health behaviors rather than weight loss programs are explained.

    2001-05-01

    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.

  19. The role of diagnostic radiology in pancreatitis

    International Nuclear Information System (INIS)

    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

    For patients with chronic pancreatitis (CP), standard surgical procedures (eg, partial or total resections, drainage procedures) are inadequate treatment options, because they do not confer pain relief and they leave patients prone to brittle diabetes and hypoglycemia. The combination of total pancreatectomy and islet autotransplantation (TP-IAT), however, can create insulin-independent and pain-free states. At our center, from August 2009 through August 2013, 61 patients with CP underwent either open or robot-assisted TP-IAT. The 30-day mortality rate was 0%. The transplanted islet equivalents per body weight ranged from 10,000 to 17,770. In all, 19% of the patients became insulin independent (after a range of 1-24 months); 27% of patients required free and no longer required analgesics. Our metabolic outcomes could have been even better if most patients had been referred at an earlier disease stage; instead, ∼80% had already undergone surgical procedures, and 91% had abnormal results on preoperative continuous glucose monitoring tests. Only if patients with CP are referred early for a TP-IAT-rather than being subjected to additional inadequate endoscopic and surgical procedures-can insulin-independent and pain-free states be accomplished in most.

    Full Text Available CONTEXT: A mediastinal pseudocyst is an unusual complication of acute and chronic pancreatitis. The ideal form of management is controversial, and various successful therapeutic interventions including surgical resection, internal or external drainage, and non-operative radiological drainage techniques have been described. Successful resolution of a mediastinal pseudocyst with endoscopic transpapillary stent placement has been described in fewer than five cases. CASE REPORT: We report a case of chronic pancreatitis with complete pancreas divisum together with a mediastinal pseudocyst and pancreatic pleural effusion in which magnetic resonance imaging and endoscopic retrograde pancreatography demonstrated communicat-ion of the abdominal pseudocyst with the posterior mediastinum through the diaphragmatic hiatus. This case was succes-sfully treated with endoscopic transpapillary nasopancreatic drain placement alone. CONCLUSION: A communicating mediastinal pseudocyst can be successfully treated by endoscopic transpapillary nasopancreatic drainage alone.

    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.

  10. 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

  12. Chronic exercise increases plasma brain-derived neurotrophic factor levels, pancreatic islet size, and insulin tolerance in a TrkB-dependent manner.

    Directory of Open Access Journals (Sweden)

    Alberto Jiménez-Maldonado

    Full Text Available BACKGROUND: Physical exercise improves glucose metabolism and insulin sensitivity. Brain-derived neurotrophic factor (BDNF enhances insulin activity in diabetic rodents. Because physical exercise modifies BDNF production, this study aimed to investigate the effects of chronic exercise on plasma BDNF levels and the possible effects on insulin tolerance modification in healthy rats. METHODS: Wistar rats were divided into five groups: control (sedentary, C; moderate- intensity training (MIT; MIT plus K252A TrkB blocker (MITK; high-intensity training (HIT; and HIT plus K252a (HITK. Training comprised 8 weeks of treadmill running. Plasma BDNF levels (ELISA assay, glucose tolerance, insulin tolerance, and immunohistochemistry for insulin and the pancreatic islet area were evaluated in all groups. In addition, Bdnf mRNA expression in the skeletal muscle was measured. PRINCIPAL FINDINGS: Chronic treadmill exercise significantly increased plasma BDNF levels and insulin tolerance, and both effects were attenuated by TrkB blocking. In the MIT and HIT groups, a significant TrkB-dependent pancreatic islet enlargement was observed. MIT rats exhibited increased liver glycogen levels following insulin administration in a TrkB-independent manner. CONCLUSIONS/SIGNIFICANCE: Chronic physical exercise exerted remarkable effects on insulin regulation by inducing significant increases in the pancreatic islet size and insulin sensitivity in a TrkB-dependent manner. A threshold for the induction of BNDF in response to physical exercise exists in certain muscle groups. To the best of our knowledge, these are the first results to reveal a role for TrkB in the chronic exercise-mediated insulin regulation in healthy rats.

    Objective Genetic alterations may contribute to chronic pancreatitis (CP) in Chinese young patients. This study was designed to investigate mutations of cationic trypsinogen (PRSS1), pancreatic secretory trypsin inhibitor or serine protease inhibitor Kazal type 1 (SPINK1), cystic fibrosis transmembrane conductance regulator (CFTR), chymotrypsin C (CTRC) and CLDN2 genes and the copy number variations (CNVs) of PRSS1 and asses associations with the development of idiopathic CP (ICP) in Chinese children. Design Retrospective. Setting A single center. Participants 75 ICP Chinese children (40 boys and 35 girls). Primary and secondary outcome measures Mutations of PRSS1, SPINK1, CFTR, CTRC and CLDN2 genes and CNVs. Results 7 patients had heterozygous mutations in PRSS1, that is, N29I (n=1), R122H or R122C (n=6). The CNVs of PRSS1 in five patients had abnormal copies (1 copy (n=4), five copies (n=1)). 43 patients had IVS3+2T>C (rs148954387) (10 homozygous and 33 heterozygous) in SPINK1. None of the PRSS1 mutation patients carried a SPINK1 mutation. Frequency of PRSS1 and SPINK1 mutations was 9.3% and 57.3%, respectively, with an overall frequency of 66.6% (50/75). In addition, one patient had a novel deletion of CFTR (GCTTCCTA from c.500 to c.508 leading to the shortened polypeptide molecule via a stop codon). Another patient had a novel missense in CLDN2 exon 2 (c.592A>C mutation). Clinically, patients with SPINK1 mutations had a higher rate of pancreatic duct stones, pancreatic pseudocyst and pancreatic calcification than those without SPINK1 mutations (pC mutation may play an important role in the pathogenesis of Chinese paediatric ICP. However, further study is needed to confirm and to investigate the role of these genes in the development of Chinese ICP. PMID:24002981

    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.

Both sequence multi-site variations (MSV and copy-number variants (CNV of the defensin-encoding genes are associated with increased risk for various diseases, including cancer and inflammatory conditions such as psoriasis and acute pancreatitis. In a case–control study, we investigated the association between MSV in DEFB104 as well as defensin gene (DEF cluster copy number (CN, and pancreatic ductal adenocarcinoma (PDAC and chronic pancreatitis (CP. Results Two groups of PDAC (N=70 and CP (N=60 patients were compared to matched healthy control groups CARLA1 (N=232 and CARLA2 (N=160, respectively. Four DEFB104 MSV were haplotyped by PCR, cloning and sequencing. DEF cluster CN was determined by multiplex ligation-dependent probe amplification. Neither the PDAC nor the CP cohorts show significant differences in the DEFB104 haplotype distribution compared to the respective control groups CARLA1 and CARLA2, respectively. The diploid DEF cluster CN exhibit a significantly different distribution between PDAC and CARLA1 (Fisher’s exact test P=0.027, but not between CP and CARLA2 (P=0.867. Conclusion Different DEF cluster b CN distribution between PDAC patients and healthy controls indicate a potential protective effect of higher CNs against the disease.

    The patient was a 69 year old man who had been diagnosed with alcoholic chronic pancreatitis and lower common bile duct (CBD) stricture. He subsequently developed cholangitis 2-3 times a year, and we replaced the endoscopic biliary stent (EBS) each time. In April 2010, he was admitted because of complication by a liver abscess and acute cholangitis. We performed percutaneous transhepatic liver abscess drainage. The inflammatory findings then rapidly improved, but the patient developed acute cholangitis due to the sludge and the stones. Then, we placed a partially covered self-expandable metallic stent (C-SEMS) in the lower CBD and performed endoscopic lithotripsy through the C-SEMS, and the cholangitis subsequently improved. Two weeks after, we removed the C-SEMS endoscopically and replaced it with a 10 Fr plastic stent; since then there have been no recurrences of cholangitis. Our experience in this case suggested that when a plastic stent is placed long-term to treat a biliary stricture associated with chronic pancreatitis, it might be useful to also control biliary sludge and stones using a C-SEMS.

We selected 9 variants from the reported GWAS and replicated the association with CP in Indian patients by genotyping 1807 unrelated Indians of Indo-European ethnicity, including 519 patients with CP and 1288 controls. The etiology of CP was idiopathic in 83.62% and alcoholic in 16.38% of 519 patients. Our study confirmed a significant association of 2 variants in CLDN2 gene (rs4409525-OR 1.71, P = 1.38 x 10-09; rs12008279-OR 1.56, P = 1.53 x 10-04 and 2 variants in MORC4 gene (rs12688220-OR 1.72, P = 9.20 x 10-09; rs6622126-OR 1.75, P = 4.04x10-05 in Indian patients with CP.

We also found significant association at PRSS1-PRSS2 locus (OR 0.60; P = 9.92 x 10-06) and SAMD12-TNFRSF11B (OR 0.49, 95% CI [0.31-0.78], P = 0.0027). A variant in the gene MORC4 (rs12688220) showed significant interaction with alcohol (OR for homozygous and heterozygous risk allele -14.62 and 1.51 respectively, P = 0.0068) suggesting gene-environment interaction. A combined analysis of the genes CLDN2 and MORC4 based on an effective risk allele score revealed a higher percentage of individuals homozygous for the risk allele in CP cases with 5.09 fold enhanced risk in individuals with 7 or more effective risk alleles compared with individuals with 3 or less risk alleles (P = 1.88 x 10-14). Genetic variants in CLDN2 and MORC4 genes were associated with CP in Indian patients. PMID:26820620

    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 study the effects of free fatty acids on insulin secretion and expression of SUR1 gene in rat pancreatic B cells in vitro, and to explore the molecular mechanisms in lipotoxicity inducing insulin secretion dysfunction, pancreatic islet cells were isolated and digested from male SD rats.Purified islets were incubated with either 0.25 mmol/L palmitate or 0. 125 mmol/L oleate for 48 h in vitro. Then islets were stimulated with either 5.6 mmol/L or 16.7 mmol/L glucose for 1 h. Insulin release was measured by using radioimmunoassay, and the expression of SUR1 gene mRNA was quantified by reserve transcription-polymerase chain reaction (RT-PCR). The islets exposed to both palmitate and oleate for 48 h showed an increased basal and a decreased glucose-indused insulin release as compared with control islets. Palmitate increased basal insulin secretion by 110 % (P<0.01), decreased glucose stimulated insulin secretion by 43 % (P<0.01) ; while oleate increased basal insulin secretion by 80 % (P<0.01) and decreased glucose stimulated insulin secretion by 32 % (P<0.05). RT-PCR showed that oleate significantly suppressed SUR1 gene expression by 64 % (P<0.01)as compared with the control group, while palmitate group manifested a light decrease of 15 % (P >0.05) of SUR1 gene expression. Our results suggested that chronic exposure to free fatty acids of pancreatic β cells inhibited glucose stimulated insulin secretion. Regulation of SUR1 gene expression may be involved in such effects, which may also be one of the molecular mechanisms in lipotoxocity inducing β cells secretion dysfunction.

    Full Text Available Abstract Introduction Mediastinal pancreatic pseudocysts represent a rare complication of acute or chronic pancreatitis. Case presentation A 55-year-old man with a history of chronic pancreatitis was admitted with intermittent dyspnea, dysphagia and weight loss. Chest X-ray, computed tomography and magnetic resonance imaging revealed a large paracardial pancreatic pseudocyst causing cardiac and esophageal compression. Conclusion Mediastinal pancreatic pseudocysts are a rare complication of chronic pancreatitis. These pseudocysts may lead to isolated thoracic symptoms. For accurate diagnostic and therapy planning, a multimodal imaging approach is necessary.

  1. Helicobacter pylori and pancreatic diseases

    2014-01-01

    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.

  3. Preliminary application of 3.0 T proton MR Spectroscopy in differential diagnosis of pancreatic cancer and pancreatitis

    International Nuclear Information System (INIS)

    Objective: To observe 1H-MRS appearance of acute pancreatitis, chronic pancreatitis and pancreatic cancer, and to analyze the changes in metabolites. Methods: Pancreas spectroscopies of 45 subjects were acquired by single-voxel PRESS sequence on 3.0 T MR scanner. The subjects were divided into three groups, i.e., acute edematous pancreatitis (n=15), chronic pancreas (n=10), and pancreatic cancer (n=20). Visibilities of metabolite were compared between pancreatitis and pancreatic cancer group. The ratio of cholesterol and the olefinic region of fatty acids (Chol+ Unsat) peak height to lipid (Lip) peak height (Chol+Unsat/Lip) was calculated in each group. One-way ANOVA with post hoc comparisons was performed among the three groups. Results: There were three major resonance peaks in the spectra, Lip, Chol+Unsat, and choline. There was no significant difference in the visible rate of choline (χ=0.104, P= 0.748) between pancreatitis and pancreatic cancer group. The mean value of Chol+Unsat/Lip was 0.179±0.056 for acute pancreatitis, 0.274±0.099 for chronic pancreatitis, 0.325±0.187 for pancreatic cancer, and they were statistically different among the three groups (F=5.011, P=0.011). Furthermore, statistically significant difference in Chol+Unsat/Lip was observed between acute pancreatitis group and chronic pancreatitis group or pancreatic cancer group (both P<0.05), but not between chronic pancreatitis and pancreatic cancer group (P=0.712). Conclusion: Chol+Unsat/Lip may be helpful in differentiating acute pancreatitis from chronic pancreatitis and pancreatic cancer. (authors)

    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

  6. 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

    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

    Renal diets typically incorporate protein and phosphorus restriction, supplement with potassium and Omega-3 fatty acids, and address metabolic acidosis. Compared to "maintenance" diets, these modifications appear to benefit cats with chronic kidney disease (CKD). However, there is limited data in cats justifying the specific amounts of the nutrients used in these diets, and there is little evidence supporting protein restriction in cats with CKD. Energy intake, maintenance of body weight, and muscle and body condition need to be addressed, and may take precedence over special diets. Further research is needed to better define optimum diets for cats with CKD. PMID:27593575

    1999-01-01

    Full Text Available Biochemical and hematimetric indicators of inflammation and cell damage were correlated with bilirubin and hepatic and pancreatic enzymes in 30 chronic male alcoholics admitted into psychiatric hospital for detoxification and treatment of alcoholism. Aspartate aminotransferase, alanine aminotransferase, gamma-glutamyltransferase, alkaline phosphatase, and total bilirubin were altered, respectively, in 90%, 63%, 87%, 23% and 23% of the cases. None of the indicators of inflammation (lactic dehydrogenase, altered in 16% of the cases; alpha-1 globulin, 24%; alpha-2 globulin, 88%; leucocyte counts, 28% was correlated with alterations of bilirubin or liver enzymes. Lactic dehydrogenase was poorly sensitive for detection of hepatocytic or muscular damage. Alterations of alpha-globulins seemed to have been due more to alcohol metabolism-induced increase of lipoproteins than to inflammation. Among indicators of cell damage, serum iron, increased in 40% of the cases, seemed to be related to liver damage while creatine phosphokinase, increased in 84% of the cases, related to muscle damage. Hyperamylasemia was found in 20% of the cases and significantly correlated with levels of bilirubin, alkaline phosphatase and gamma-glutamyltransferase. It was indicated that injuries of liver, pancreas, salivary glands, and muscle occurred in asymptomatic or oligosymptomatic chronic alcoholics.

  17. A conservative assessment of the major genetic causes of idiopathic chronic pancreatitis: data from a comprehensive analysis of PRSS1, SPINK1, CTRC and CFTR genes in 253 young French patients.

    Directory of Open Access Journals (Sweden)

    Emmanuelle Masson

    Full Text Available Idiopathic chronic pancreatitis (ICP has traditionally been defined as chronic pancreatitis in the absence of any obvious precipitating factors (e.g. alcohol abuse and family history of the disease. Studies over the past 15 years have revealed that ICP has a highly complex genetic architecture involving multiple gene loci. Here, we have attempted to provide a conservative assessment of the major genetic causes of ICP in a sample of 253 young French ICP patients. For the first time, conventional types of mutation (comprising coding sequence variants and variants at intron/exon boundaries and gross genomic rearrangements were screened for in all four major pancreatitis genes, PRSS1, SPINK1, CTRC and CFTR. For the purposes of the study, synonymous, intronic and 5'- or 3'-untranslated region variants were excluded from the analysis except where there was persuasive evidence of functional consequences. The remaining sequence variants/genotypes were classified into causative, contributory or neutral categories by consideration of (i their allele frequencies in patient and normal control populations, (ii their presumed or experimentally confirmed functional effects, (iii the relative importance of their associated genes in the pathogenesis of chronic pancreatitis and (iv gene-gene interactions wherever applicable. Adoption of this strategy allowed us to assess the pathogenic relevance of specific variants/genotypes to their respective carriers to an unprecedented degree. The genetic cause of ICP could be assigned in 23.7% of individuals in the study group. A strong genetic susceptibility factor was also present in an additional 24.5% of cases. Taken together, up to 48.2% of the studied ICP patients were found to display evidence of a genetic basis for their pancreatitis. Whereas these particular proportions may not be extrapolable to all ICP patients, the approach employed should serve as a useful framework for acquiring a better understanding of the

    Pancreatic panniculitis is a rare skin disorder that occurs in 2–3% of pancreatic diseases, mostly associated with acute or chronic pancreatitis. Its pathophysiology is still unclear, but the release of pancreatic enzymes in circulation can be responsible for this disorder. The typical histological features are adipocyte necrosis with neutrophils infiltrate and typical “ghost cells”. Its treatment, clinical course and prognosis are usually related with the pancreatic disease. We present a ...

    Pancreatic pseudocysts are the most common cystic lesions of the pancreas and may complicate acute pancreatitis, chronic pancreatitis, or pancreatic trauma. While the majority of acute pseudocysts resolve spontaneously, few may require drainage. On the other hand, pancreatic cystic tumors, which usually require extirpation, may disguise as pseudocysts. Hence, the distinction between the two entities is crucial for a successful outcome. We conducted this study to highlight the fundamental diff...

  1. Pathways to injury in chronic pancreatitis: decoding the role of the high-risk SPINK1 N34S haplotype using meta-analysis.

    Directory of Open Access Journals (Sweden)

    Elie Aoun

    Full Text Available BACKGROUND: The complex interactions between recurrent trypsin-mediated pancreatic injury, alcohol-associated pancreatic injury and SPINK1 polymorphisms in chronic pancreatitis (CP are undefined. We hypothesize that CP occurs as a result of multiple pathological mechanisms (pathways that are initiated by different metabolic or environmental factors (etiologies and may be influenced differentially by downstream genetic risk factors. We tested this hypothesis by evaluating the differences in effect size of the high risk SPINK1 N34S haplotype on CP from multiple etiologies after combining clinical reports of SPINK1 N34S frequency using meta-analysis. METHODS AND FINDINGS: The Pubmed and the Embase databases were reviewed. We studied 24 reports of SPINK1 N34S in CP (2,421 cases, 4,857 controls using reported etiological factors as surrogates for pathways and multiple meta-analyses to determine the differential effects of SPINK1 N34S between alcoholic and non-alcoholic etiologies. Using estimates of between-study heterogeneity, we sub-classified our 24 studies into four specific clusters. We found that SPINK1 N34S is strongly associated with CP overall (OR 11.00; 95% CI: 7.59-15.93, but the effect of SPINK1 N34S in alcoholic CP (OR 4.98, 95% CI: 3.16-7.85 was significantly smaller than in idiopathic CP (OR 14.97, 95% C.I. = 9.09-24.67 or tropical CP (OR 19.15, 95% C.I. = 8.83-41.56. Studies analyzing familial CP showed very high heterogeneity suggestive of a complex etiology with an I(2 = 80.95%. CONCLUSION: The small effect of SPINK1 N34S in alcoholic subjects suggests that CP is driven through a different pathway that is largely trypsin-independent. The results also suggest that large effect sizes of SPINK1 N34S in small candidate gene studies in CP may be related to a mixture of multiple etiologic pathways leading to the same clinical endpoint.

  2. Evaluation of pancreatic scintigram in the diagnosis of pancreatic diseases

    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)

    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.

    2004-07-01

    Full Text Available CONTEXT: The tumor protein p53-induced nuclear protein 1 (TP53INP1 gene was found using DNA microarray technology as an overexpressed gene in acute pancreatitis. However, expression of TP53INP1 in chronic pancreatitis has not been previously reported. OBJECTIVE: This study investigated TP53INP1 gene expression and its relationship with p53 and apoptosis in spontaneous chronic pancreatitis in the Wistar-Bonn/Kobori rat. METHODS: Ninety four-week-old male Wistar-Bonn/Kobori rats were fed a special breeding diet until sacrifice. Camostat mesilate (n=30 or a herbal medicine (Saiko-keishi-to; n=30 were mixed with the diet, while the other 30 rats were untreated. The rats were sacrificed every 4 weeks for 20 weeks, and the pancreas was examined. In addition, 6 four-week-old male Wistar-Bonn/Kobori rats were sacrificed and studied as starting reference. Finally, Wistar rats (n=36 were studied as controls. MAIN OUTCOME MEASURE: TP53INP1 mRNA expression was determined by reverse transcription-polymerase chain reaction using semi-quantitative analysis, direct sequencing and in situ hybridization. RESULTS: TP53INP1 mRNA was strongly expressed at 12 weeks when chronic pancreatitis developed, with a second peak at 20 weeks. The expression kinetics of TP53INP1 mRNA paralleled acinar cell apoptosis assessed by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling. The p53 mRNA expression showed a single peak at 12 weeks. In situ hybridization revealed that TP53INP1 mRNA was expressed mainly in acinar cells. Therapeutic drugs such as camostat mesilate and a herbal medicine Saiko-keishi-to suppressed the TP53INP1 mRNA expression. TP53INP1 mRNA induction in acinar cells was confirmed with in vitro experiments using an arginine-induced rat pancreatic acinar AR4-2J cell injury model. CONCLUSIONS: TP53INP1 expression may reflect the acute-phase response and apoptosis of acinar cells in the course of chronic pancreatitis.

    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

  12. 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.)

  15. An Insight into the Role of Human Pancreatic Lithostathine

    Directory of Open Access Journals (Sweden)

    Patard L

    2003-03-01

    Full Text Available Human lithostathine was initially isolated from pancreatic stones in patients with alcoholic calcifying chronic pancreatitis. It is secreted into the pancreatic juice where it was believed to inhibit stone formation. The N-terminal undecapeptide was assumed to play an important role in the mechanism, by adsorption to the crystal surface. Later, the role of lithostathine in calcite formation and growth was questioned, together with the associated mechanism of action. In particular, although lithostathine adsorbs on calcite crystal, this property does not now seem to be specific. Moreover, the N-terminal undecapeptide is not likely to have, by itself, the function of the entire protein. The different aspects of this controversy are reviewed and discussed, particularly in the light of recent structural biology. Comparative biological data now available allow us to draw an interesting parallel between lithostathine and other related proteins. Finally, lithostathine might affect stone formation and may also have another function which could be investigated in the other proteins belonging to the same structural family.

Material and methods. We have observed 86 patients with CP and first diagnosed DM. The assessment of carbohydrate metabolism compensation via HbA1 с level was done using analyzer IMX «Abbot» (USA. Results. At the 1st step of DM treatment we recommended the lifestyle modification and usage of creon 30-60.000 units daily. At the 2d step of treatment if necessary we added glyclazide. Conclusion. We have detected that irrespective of duration of alcoholic form of CP in case of subsequent DM development the lifestyle modification together with replacement ferment therapy in 90% of cases were non-effective. In the result of the research it was established, in case of 3 and more relapses per year in alcoholic form of CPthe probability of achievement of target HbA1 с level in complex with lifestyle changes and replacement ferment therapy was twice low, in connection with that fact the indication of oral anti-diabetic agents became necessary.

    Total pancreatectomy and islet autotransplantation is a cutting-edge technique to treat chronic pancreatitis and postoperative diabetes. A major obstacle has been low islet cell survival due largely to the innate inflammatory response. Connexin43 (Cx43) channels play a key role in early inflammation and have proven to be viable therapeutic targets. Even if cell death due to early inflammation is avoided, insufficient vascularization is a primary obstacle to maintaining the viability of implanted cells. We have invented technologies targeting the inflammatory response and poor vascularization: a Cx43 mimetic peptide that inhibits inflammation and a novel prevascularized tissue engineered construct. We combined these technologies with isolated islets to create a prevascularized bioartificial pancreas that is resistant to the innate inflammatory response. Immunoconfocal microscopy showed that constructs containing islets express insulin and possess a vascular network similar to constructs without islets. Glucose stimulated islet-containing constructs displayed reduced insulin secretion compared to islets alone. However, labeling for insulin post-glucose stimulation revealed that the constructs expressed abundant levels of insulin. This discrepancy was found to be due to the expression of insulin degrading enzyme. These results suggest that the prevascularized bioartificial pancreas is potentially a tool for improving long-term islet cell survival in vivo. PMID:26788521

    There was remarkable progress in the understanding of the role genetic risk factors in chronic pancreatitis.These factors seem to be much more important than thought in the past.The rare autosomal-dominant mutations N29I and R122H of PRSS1(cationic trypsinogen) as well as the variant N34S of SPINK1(pancreatic secretory trypsin inhibitor) are associated to a disease onset in childhood or youth.Compared to chronic alcoholic pancreatitis the progression is slow so that for a long time only signs of acute-recurrent pancreatitis are found.Only at later time points(more than 10-15 years) there is evidence for chronic pancreatitis in the majority of patients.Acute recurrent pancreatitis may therefore be regarded as a transition state until definite signs of chronic pancreatitis are detectable.

    Full Text Available Last decade in Ukraine and many countries there is a clear tendency to increase the number of cases of pancreatic diseases. For more than century study of the pathogenesis of chronic pancreatitis it has been proposed many hypotheses. Some of them were eventually dismissed, partially confirmed by other clinical and experimental research. Significant progress in understanding the process of fibrosis in the pancreas is associated with the identification, isolation and description of pancreatic stellate cells. They present in periacinar space and have long cytoplasmic processes covered the basis of acinus. This cells can be changed from stable fat-storing to miofibroblastic phenotype. Pancreatic stellate cells perform a wide range of functions, they have the ability to contraction, proliferation, they can synthesize extracellular matrix components and influence on the surrounding cellular environment. These cells can be regarded as a morphological basis for the development of pancreatic fibrosis. Currently, for the treatment of chronic pancreatitis, the main therapy is directed on depression of secretory activity of pancreas and inactivation biogenic amines in blood. Treatment of chronic pancreatitis should aim to influence the key mechanisms of pancreatic stellate cells activation and proliferation. Understanding the biology of this cells can open potential therapeutic targets for treatment and prevention of chronic pancreatitis and other diseases accompanied by pancreatic fibrosis.

    Full Text Available ContextPancreatic stellate cell (PSC is known to be the source of fibrosis in pancreatic pathology of various etiologies. However, there is no published data on activation of PSCs in tropical calcific pancreatitis. ObjectivesThe present study was undertaken to estimate the proportion of activated stellate cells, in a semi-quantitative manner, in normal pancreas and pancreatic fibrosis due to, tropical calcific pancreatitis, alcoholic chronic pancreatitis and pancreatic adenocarcinoma. PatientsSurgically resected specimen from patients with tropical calcific pancreatitis (n=22, alcoholic chronic pancreatitis(n=16, adenocarcinoma of pancreas (n=20 and normal pancreas (n=20 were included. Main outcome measuresExpression of CD34, and alpha-smooth muscle actin (α-SMA was assessed by immunohistochemistry. Morphometry was performed by a pointcounting procedure and CD34 positive areas were excluded from α-SMA positive areas for estimating activated PSCs. StatisticsThe one-way ANOVA and the Tukey multiple comparison test were used to compare the proportion ofactivated stellate cells among the four categories. ResultsIn all the disease conditions studied, namely, tropical calcific pancreatitis (16.7±14.5%, mean±SD, alcoholic chronic pancreatitis (13.6±12.4% and pancreatic adenocarcinoma (22.8±14.4%, there was highly significant (P<0.001 increased percentage of activated PSCs compared to normal pancreas (-0.9±6.4%. Proportion of activated PSCs in tropical calcific pancreatitis was similar to that in cases of alcoholic chronic pancreatitis and pancreatic adenocarcinoma. Such activation is documented for the first time in tropical calcific pancreatitis while it is known for the other causes. ConclusionsThe present study suggests that a final common pathway of PSC activation leads to fibrogenesis in tropical calcific pancreatitis just as in other pancreatic pathologies.

    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.

    BACKGROUND:Telomerase activity is reported to be speciifc and frequent in human pancreatic cancer. We conducted this study to assess the usefulness of monitoring telomerase activity in exfoliated cells obtained by pancreatic duct brushing during endoscopic retrograde cholangiopancreatography (ERCP) for the diagnosis of pancreatic cancer. METHODS:Exfoliated cells obtained by pancreatic duct brushing during ERCP from 21 patients (18 with pancreatic cancer, 3 with chronic pancreatitis) were examined. Telomerase activity was detected by polymerase chain reaction and telomeric repeat ampliifcation protocol assay (PCR-TRAP-ELISA). RESULTS:D450 values of telomerase activity were 0.446± 0.2700 in pancreatic cancer and 0.041±0.0111 in chronic pancreatitis. 77.8% (14/18) of patients with pancreatic cancer had cells with telomerase activity. None of the samples from patients with chronic pancreatitis showed telomerase activity, when the cutoff value of telomerase activity was set at 2.0. Cytological examination showed cancer cells in 66.7%(12/18) of the patients. CONCLUSIONS:Telomerase activity may be an early malignant event in pancreatic cancer development. Cytology and telomerase activity in cells obtained by pancreatic duct brushing may complement each other for the diagnosis of pancreatic cancer.

    Policies that mandate immunization have always been controversial. The controversies take different forms in different contexts. For routine childhood immunizations, many parents have fears about both short- and long-term side effects. Parental worries change as the rate of vaccination in the community changes. When most children are vaccinated, parents worry more about side effects than they do about disease. Because of these worries, immunization rates go down. As immunization rates go down, disease rates go up, and parents worry less about side effects of vaccination and more about the complications of the diseases. Immunization rates then go up. For teenagers, controversies arise about the criteria that should guide policies that mandate, rather than merely recommend and encourage, certain immunizations. In particular, policy makers have questioned whether immunizations for human papillomavirus, or other diseases that are not contagious, should be required. For healthcare workers, debates have focused on the strength of institutional mandates. For years, experts have recommended that all healthcare workers be immunized against influenza. Immunizations for other infections including pertussis, measles, mumps, and hepatitis are encouraged but few hospitals have mandated such immunizations-instead, they rely on incentives and education. Pandemics present a different set of problems as people demand vaccines that are in short supply. These issues erupt into controversy on a regular basis. Physicians and policy makers must respond both in their individual practices and as advisory experts to national and state agencies. The articles in this volume will discuss the evolution of national immunization programs in these various settings. We will critically examine the role of vaccine mandates. We will discuss ways that practitioners and public health officials should deal with vaccine refusal. We will contrast responses of the population as a whole, within the

    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.

  19. Improved Pancreatic Adenocarcinoma Diagnosis in Jaundiced and Non-Jaundiced Pancreatic Adenocarcinoma Patients through the Combination of Routine Clinical Markers Associated to Pancreatic Adenocarcinoma Pathophysiology.

    Full Text Available There is still no reliable biomarker for the diagnosis of pancreatic adenocarcinoma. Carbohydrate antigen 19-9 (CA 19-9 is a tumor marker only recommended for pancreatic adenocarcinoma follow-up. One of the clinical problems lies in distinguishing between this cancer and other benign pancreatic diseases such as chronic pancreatitis. In this study we will assess the value of panels of serum molecules related to pancreatic cancer physiopathology to determine whether alone or in combination could help to discriminate between these two pathologies.CA 19-9, carcinoembryonic antigen (CEA, C-reactive protein, albumin, insulin growth factor-1 (IGF-1 and IGF binding protein-3 were measured using routine clinical analyzers in a cohort of 47 pancreatic adenocarcinoma, 20 chronic pancreatitis and 15 healthy controls.The combination of CA 19-9, IGF-1 and albumin resulted in a combined area under the curve (AUC of 0.959 with 93.6% sensitivity and 95% specificity, much higher than CA 19-9 alone. An algorithm was defined to classify the patients as chronic pancreatitis or pancreatic cancer with the above specificity and sensitivity. In an independent validation group of 20 pancreatic adenocarcinoma and 13 chronic pancreatitis patients, the combination of the four molecules classified correctly all pancreatic adenocarcinoma and 12 out of 13 chronic pancreatitis patients.Although this panel of markers should be validated in larger cohorts, the high sensitivity and specificity values and the convenience to measure these parameters in clinical laboratories shows great promise for improving pancreatic adenocarcinoma diagnosis.

    2015-12-01

    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.

    BACKGROUND: Diagnostic parameters that can predict the presence of chronic pancreatitis (CP) in patients with recur-rent pain due to pancreatitis would help to direct appropri-ate therapy. This study aimed to compare the serum levels of monocyte chemoattractant protein-1 (MCP-1), transforming growth factor-β1 (TGF-β1), nerve growth factor (NGF), resis-tin and hyaluronic acid (HA) in patients with recurrent acute pancreatitis (RAP) and CP to assess their ability to differenti-ate the two conditions. METHODS: Levels of serum markers assessed by enzyme-linked immunosorbent assay (ELISA) were prospectively com-pared in consecutive patients with RAP, CP and in controls, and stepwise discriminant analysis was performed to identify the markers differentiating RAP from CP. RESULTS: One hundred and thirteen consecutive patients (RAP=32, CP=81) and 78 healthy controls were prospectively enrolled. The mean (SD) age of the patients was 32.0 (14.0) years; 89 (78.8%) were male. All markers were signiifcantly higher in CP patients than in the controls (P CONCLUSION: Serum resistin is a promising marker to dif-ferentiate between RAP and CP and needs validation in future studies, especially in those with early CP.

    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.

    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.

    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

These include 20 patients of acute pancreatitis, 12 patients of chronic pancreatitis, and 41 patients of pancreatic tumor. Remaining 47 patients were proved to have normal pancreas. CT permitted correct diagnosis in 108 of 120 patients with diagnostic accuracy 91%, sensitivity 95%, and specificity 79%. Predictive value of positive CT diagnosis was 93% and that of negative diagnosis was 82%. Commonly observed CT findings of acute pancreatitis were diffuse pancreatic enlargement (75%), obliteration of peripancreatic fat planes (70%), peripancreatic 'Dirty fat' (50%), and renal fasical thickening (50%). Abscess formation, pseudocyst formation, phlegmon, and fluid collection were the complications of acute pancreatitis in order of frequency. In chronic pancreatitis, pancreatic calcification was the most frequent (58%) and specific CT finding. Pancreas size were normal in 2 patients (16%), atrophic in 5 patients (42%), and enlarged in 5 patients (42%). Of 40 patients with pancreatic cancer, 36 patients showed pancreatic mass on CT, and 18 were with central low density. Other findings of pancreatic cancer were obliteration of peripancreatic fat plane (60%), biliary dilation (30%), and secondary pancreatitis (18%). Liver and lymph nodes metastases were found in 27 patients (68%) at the time of CT scanning.

  16. Antibiotics in acute necrotizing pancreatitis --- perspective of a developing country

    International Nuclear Information System (INIS)

    Prophylactic antibiotics in acute necrotizing pancreatitis is controversial. The mortality of acute necrotizing pancreatitis is 8-25% in the western world. In view of the limited resources available for managing the complications of infected pancreatitis in developing countries, the use of prophylactic antibiotics may be recommended in selected cases. Various antibiotics show good penetration into the pancreatic tissue; imipenem and quinolones have better penetration. Clinical trials on the use of prophylactic antibiotics in necrotizing pancreatitis have been reviewed. Prophylactic antibiotics have been considered if greater than 30% pancreatic necrosis as documented by CT scan. Imipenem can be given for a duration of 10 to 14 days if no systemic complications are present. In a developing country where the cost of managing complications of pancreatitis can be a limiting factor for patients, the use of prophylactic antibiotics early on in the disease in selected cases can be beneficial.

    For the quantitative measurement of pancreatic oncofetal antigen (POA), an enzyme immunoassay for POA has been developed, and is based on the sandwich method using antibody-coupled glass beads and enzyme (peroxidase)-labelled antibody. Serum POA concentrations were increased significantly in patients with pancreatic cancer, but not in those with chronic pancreatitis or other miscellaneous diseases, or in normal subjects. It is concluded that the enzyme immunoassay could be used for the assay ...

    Last decade in Ukraine and many countries there is a clear tendency to increase the number of cases of pancreatic diseases. For more than century study of the pathogenesis of chronic pancreatitis it has been proposed many hypotheses. Some of them were eventually dismissed, partially confirmed by other clinical and experimental research. Significant progress in understanding the process of fibrosis in the pancreas is associated with the identification, isolation and description of pancreatic s...

    Full Text Available It is well known that the prognosis of pancreatic cancer is extremely poor, even when treated with radical surgery. The overall 5 year survival rate following surgical intervention is around 10%.With the increasing use of CT scans for other reasons not related to pancreas, a variety of neoplastic and non - neoplastic lesions are increasingly encountered in clinical practice. The distinction of these lesions has significant therapeutic and prognostic implications. Regarding ductal carcinoma, key distinguishing features from chronic pancreatitis and a discussion of the concept of pancreatic intraepithelial neoplasia ( PanIN are included. Precursors, mo lecular carcinogenesis, risk factors and different morphological patterns of tumors arising from exocrine pancreas are discussed. Research on early detection is ongoing. Screening of people with a family history of hereditary pancreatitis plays an importan t role in the early detection of ductal carcinoma of pancreas.

    AIM: To study the patients with main pancreatic duct dilation on computed tomography (CT) and thereby to provide the predictive criteria to identify patients at high risk of significant diseases, such as pancreatic cancer, and to avoid unnecessary work up for patients at low risk of such diseases.METHODS: Patients with dilation of the main pancreatic duct on CT at Emory University Hospital in 2002 were identified by computer search. Clinical course and ultimate diagnosis were obtained in all the identified patients by abstraction of their computer database records.RESULTS: Seventy-seven patients were identified in this study. Chronic pancreatitis and pancreatic cancer were the most common causes of the main pancreatic duct dilation on CT. Although the majority of patients with isolated dilation of the main pancreatic duct (single duct dilation) had chronic pancreatitis, one-third of patients with single duct dilation but without chronic pancreatitis had pancreatic malignancies, whereas most of patients with concomitant biliary duct dilation (double duct dilation) had pancreatic cancer.CONCLUSION: Patients with pancreatic double duct dilation need extensive work up and careful follow up since a majority of these patients are ultimately diagnosed with pancreatic cancer. Patients with single duct dilation, especially such patients without any evidence of chronic pancreatitis, also need careful follow-up since the possibility of pancreatic malignancy, including adenocarcinoma and intraductal papillary mucinous tumors, is still high.
