    Full Text Available Fundamento y objetivo: la estrecha relación anatómica del páncreas con los vasos esplénicos y el bazo es responsable de complicaciones esplénicas en el curso de la pancreatitis aguda. El objetivo es presentar dos casos clínicos de pancreatitis aguda grave que sufrieron infarto esplénico como complicación de la enfermedad pancreática. Pacientes, participantes: en un periodo de tres meses, dos pacientes fueron diagnosticados de infarto esplénico secundario a pancreatitis aguda. En ambos casos el diagnóstico y seguimiento evolutivo del infarto esplénico se hizo a través de tomografía axial computerizada. Resultados: en el primer paciente, las imágenes muestran de forma inequívoca la afectación de la arteria esplénica por el proceso inflamatorio pancreático. En el segundo, no se pudo demostrar afectación de los vasos esplénicos, por lo que la única posible explicación etiológica es un incremento de coagulabilidad intravascular. Conclusiones: sería recomendable añadir las complicaciones esplénicas al conjunto de complicaciones graves extrapancreáticas de la pancreatitis aguda. La tomografía axial computerizada es de gran utilidad para la detección y seguimiento de las complicaciones esplénicas de la pancreatitis aguda.Background and objective: the close anatomic relationship of the pancreas with the splenic vessels and the spleen is responsible for splenic complications in the course of acute pancreatitis. Our objective was to report two cases of severe acute pancreatitis complicated by splenic infarction. Patients: in a three-month period of time two patients were diagnosed with splenic infarction secondary to acute pancreatitis. In both cases splenic infarction diagnosis and follow-up were carried out using computed tomography. Results: in the first case images clearly showed a narrowing of the splenic artery due to the inflammatory pancreatic condition. In the second case no involvement of the splenic vessels could

    Full Text Available BACKGROUD: Recent studies indicate that hyperthermia can change inflammatory mechanisms and protect experimental animals from deleterious effects of secretagogue-induced acute pancreatitis AIM: To evaluate the effects of hyperthermia post-treatment on cerulein-induced acute pancreatitis in rats METHODS: Twenty animals were divided in two groups: group I (n = 10, rats with cerulein-induced acute pancreatitis undergone hyperthermia, and group II (n = 10, animals with cerulein-induced acute pancreatitis that were kept normothermic. In all groups, amylase serum levels, histologic damage, vascular permeability and pancreatic water content were assessed. Acute pancreatitis was induced by administration of two cerulein injections (20 mcg/kg. A single dose of Evans' blue dye was administered along with the second dose of cerulein. All animals also received a subcutaneous injection of saline solution. After this process, animals undergone hyperthermia were heated in a cage with two 100 W lamps. Body temperature was increased to 39.5ºC and maintained at that level for 45 minutes. Normothermia rats were kept at room temperature in a second cage RESULTS: Control animals had typical edema, serum amylase activity and morphologic changes of this acute pancreatitis model. Hyperthermia post-treatment ameliorated the pancreatic edema, whereas the histologic damage and the serum amylase level remained unchanged CONCLUSIONS: The findings suggest a beneficial effect of the thermal stress on inflammatory edema in experimental acute pancreatitis.RACIONAL: Estudos recentes indicam que a hipertermia pode modificar mecanismos inflamatórios e proteger animais experimentais dos efeitos deletérios da pancreatite aguda induzida por secretagogos OBJETIVO: Avaliar a eficácia da hipertermia como tratamento da pancreatite aguda induzida por ceruleína em ratos MÉTODOS: Vinte animais foram divididos em dois grupos: grupo I (n = 10, ratos com pancreatite aguda induzida por

    Full Text Available Hypercalcemia due to hyperparathyroidism is a rare etiology for acute pancreatitis, oscillating between 1.5 and 7% in the different series. Although the cause-effect relationship and the pathophysiology of the condition are not clear, it seems that the association among them is not incidental, and serum calcium could be a major risk factor, so that pancreatitis would come to occur during severe hypercalcemia attacks. Mutations in different genes have been proposed as well to justify why only some patients with primary hyperparathyroidism and hypercalcemia develop acute pancreatitis. References to cases like these ones are rare in the literature. We report two patients with acute pancreatitis associated with hyperparathyroidism and hypercalcemia, one of them with a fatal outcome.La hipercalcemia secundaria a hiperparatiroidismo es una causa rara de pancreatitis aguda, variando entre el 1,5-7% según las series consultadas. Aunque la relación causal y la fisiopatología del proceso no están totalmente aclaradas, parece claro que la asociación no es incidental y que los niveles de calcio sérico serían un factor de riesgo mayor, desencadenándose los cuadros de pancreatitis durante las crisis de hipercalcemia. También se han descrito alteraciones en diversos genes que podrían estar implicados, justificando por qué sólo unos pocos pacientes con hiperparatiroidismo primario e hipercalcemia sufren pancreatitis aguda. Existen muy pocas referencias en la literatura a casos como los que nos ocupan. Presentamos a continuación dos pacientes con cuadros de pancreatitis aguda asociados a hiperparatiroidismo e hipercalcemia, uno de ellos con desenlace fatal.

  6. Nutritional support in patients with severe acute pancreatitis Soporte nutricional en pacientes con pancreatitis aguda grave

    Full Text Available Severe acute pancreatitis is associated with a systemic inflammatory response leading to a hypermetabolic, hypercatabolic condition; for those reasons, patients suffering from this disease require an excellent artificial nutritional support in order to maintain the structural integrity and the function of vital organs with minimal pancreatic secretion. Total parenteral nutrition has been the standard practice in the treatment of patients with severe acute pancreatitis because of the favorable outcomes of early nutritional support while avoiding pancreatic stimulation; however, recent evidence suggests there are potentially greater benefits with enteral as compared with parenteral nutrition, including fewer septic and metabolic complications and lesser costs. That is why present guidelines for the management of acute pancreatitis recommend that enteral instead of parenteral nutrition be used in patients with severe acute pancreatitis. La pancreatitis aguda, especialmente en su forma grave, está asociada con una respuesta inflamatoria sistémica que lleva a un estado de hipermetabolismo e hipercatabolismo, en el que se requiere un excelente soporte nutricional que permita mantener la integridad estructural y la función de los órganos vitales con un estímulo mínimo de la secreción pancreática. La nutrición parenteral total era el soporte de elección, que permitía obtener todos los beneficios de la nutrición temprana sin estimular la secreción pancreática; pero la evidencia actual muestra mayores beneficios con la nutrición enteral, porque se asocia con menos complicaciones infecciosas y metabólicas y con disminución en los costos. Por ello las guías actuales de tratamiento de la pancreatitis aguda grave recomiendan como primera elección el soporte nutricional enteral.

    Full Text Available A pancreatite aguda é uma patologia grave e com considerável morbidade e mortalidade. Vários fatores são apontados como possíveis causas de pancreatite aguda. Neste relato, será apresentado um caso de pancreatite aguda com possível associação causal com um inibidor seletivo de recaptura de serotonina: sertralina. Após um mês de tratamento com sertralina, uma paciente do sexo feminino, 55 anos, desenvolveu forte dor abdominal e elevação da amilase sérica. Após internação e retirada da sertralina, seus sintomas remitiram e os níveis de amilase voltaram ao normal. Pela potencial gravidade do quadro e pelo amplo uso desta medicação, tal associação deve ser lembrada em investigações de casos de pancreatite aguda.Acute pancreatitis is a severe disease with considerable morbidity and mortality. Many risk factors are causally related to acute pancreatitis. In this report, a case of acute pancreatitis with possible causal relationship with the use of a selective serotonin reuptake inhibitor, sertraline, will be discussed. After one month of treatment with sertraline, a female patient, 55 years-old, developed a severe abdominal pain and showed a serum amylase elevation. She was admitted to the hospital and the use of sertraline was interrupted. After that, the symptoms remitted and the serum amylase level returned to normal. Because of the potential severity of this disease and the widespread use of sertraline, this association should be reminded when investigating possible causes for acute pancreatitis.

    Full Text Available La pancreatitis aguda es un proceso inflamatorio reversible. La hipertrigliceridemia como etiología de la pancreatitis aguda varía entre un 1,3 y un 11%, de acuerdo a la literatura, cuando los niveles de triglicéridos alcanzan valores por encima de 1.000 mg/dl; sin embargo, la hipertrigliceridemia se observa en un 12 a un 39% de las pancreatitis agudas como factor asociado. El objetivo del tratamiento médico es aumentar la actividad de la lipoproteinlipasa y aumentar la degradación de los quilomicrones; disminuyendo así los valores plasmáticos de triglicéridos a niveles menores de 500 mg/dl, incluso a menos de 200 mg/dl si es posible con diferentes estrategias, entre ellas la insulina. En el presente artículo, presentamos dos casos clínicos de pancreatitis severas inducidas por hipertrigliceridemia, manejadas con terapia de infusión de insulina con adecuada respuesta clínica y paraclínica con disminución significativa de los niveles de triglicéridos, 48 horas postratamiento.Acute pancreatitis is a reversible inflammatory process. Hypertriglyceridemia as a cause of acute pancreatitis reaches frequencies of 1.3-11% according to the literature when triglyceride levels reach values over 1,000 mg/dl; nevertheless hypertriglyceridemia is observed in 12-39% of acute pancreatitis cases as an associated factor. The objective of medical treatment is to increase lipoprotein-lipase activity, and to increase chylomicron breakdown thus diminishing serum triglycerides to levels smaller than 500 or even 200 mg/dl (when possible using a variety of strategies including insulin administration. In the present article, we report two cases of severe pancreatitis induced by hypertriglyceridemia that were managed with insulin infusion; both responded adequately, as measured by a significant reduction of triglyceride levels at 48 hours post-treatment.

    Full Text Available Hasta el 30% de los pacientes con pancreatitis aguda son diagnosticados de una pancreatitis aguda idiopática tras un estudio inicial que debe incluir una anamnesis completa, exploración física, análisis con determinación de calcio y triglicéridos y al menos una ecografía abdominal. Esta situación representa un reto diagnóstico, aunque en la mayoría de los casos se encuentra una causa que justifique la pancreatitis tras realizar diferentes exploraciones diagnósticas. En los últimos años la ecoendoscopia está demostrando ser de gran utilidad en el estudio de estos pacientes, produciendo a cambio una baja morbilidad. En este artículo hacemos una revisión del papel de la ecoendoscopia en el estudio etiológico de la pancreatitis aguda idiopática.Up to 30% of patients with acute pancreatitis are diagnosed of idiopathic acute pancreatitis after an initial evaluation including a complete clinical history, physical examination, analysis with calcium and triglycerides determination, and at least one transabdominal ultrasonography. Unexplained pancreatitis represents a diagnostic challenge, although after different explorations a cause is found in the majority of these patients. During the last years endosonography has proved to be a low morbidity exploration very useful in the evaluation of patients with this entity. In this article we review the role of endosonography in the etiologic study of patients with idiopathic acute pancreatitis.

    Full Text Available BACKGROUND: Severe acute pancreatitis is present in up to 25% of patients with acute pancreatitis, with considerable mortality. Changes in the management of acute pancreatitis in the last 2 decades contributed to reduce the mortality. AIM: To show the evolution in the management of severe acute pancreatitis, comparing two different approaches. METHODS: All patients with severe acute pancreatitis from 1999 to 2005 were included. We compared the results of a retrospective review from 1999 to 2002 (group A with a prospective protocol, from 2003 to 2005 (group B. In group A severe pancreatitis was defined by the presence of systemic or local complications. In group B the Atlanta criteria were used to define severity. The variables analyzed were: age, gender, etiology, APACHE II, leukocytes, bicarbonate, fluid collections and necrosis on computed tomography, surgical treatment and mortality. RESULTS: Seventy-one patients were classified as severe, 24 in group A and 47 in group B. The mean APACHE II in groups A and B were 10.7 ± 3.5 and 9.3 ± 4.5, respectively. Necrosis was seen in 12 patients (50% in group A and in 21 patients (44.7% in group B. Half of the patients in group A and two (4.3% in group B underwent to pancreatic interventions. Mortality reached 45.8% in group A and 8.5% in group B.

    Full Text Available Introducción: la pancreatitis aguda (PA es una enfermedad clínica común que puede ser desde leve hasta fatal. En el 40 % de los casos es de origen biliar, y es causada por una obstrucción de la ampolla de Váter por barro biliar o por cálculos. En el diagnóstico de la pancreatitis aguda de origen biliar (PAB se emplean métodos invasivos como la colangiopancreatografía endoscópica retrógrada (CPRE, la cual se asocia a morbilidad y mortalidad, y métodos no invasivos como la colangiopancreatografía magnética (CRM, que emerge como modalidad diagnóstica en los centros de tercer y cuarto nivel de complejidad. Métodos: se evaluaron las características diagnósticas de la CRM a través de los registros históricos de pacientes que ingresaron a un hospital universitario de nivel IV a los que se les realizó CRM y CPRE. Esta última fue considerada el método de referencia para la evaluación. Resultados: Para la CRM se determinó una sensibilidad del 97 % y una especificidad del 44 % para la detección de coledocolitiasis, con un valor predictivo positivo de 0,35 y un valor predictivo negativo de 0,99. Algunos de estos resultados son inferiores a los documentados en la bibliografía mundial. Conclusiones: la CRM permite obtener imágenes precisas de la vía biliar, en un ambiente seguro y sin riesgos para el paciente. Esta técnica tiene una capacidad de detección de coledocolitiasis que oscila entre el 78 y el 97 %, resultado que concuerda con lo descrito en otros estudios.

    Full Text Available Gastrointestinal symptoms in patients with SLE are common, specifically abdominal pain. However, the rate of pancreatic diseases is much lower and does not reach 5% according to published series in Europe and the USA. This association between SLE and pancreatic disease is basically at the expense of episodes of acute pancreatitis. An association with chronic pancreatitis is much more uncommon, and only four articles have been published showing this relationship. Three cases of SLE-associated pancreatitis are described, and disease onset, etiological factors, and clinical progression are analyzed. A review of the literature and a brief discussion about pathophysiological mechanisms and the role of corticosteroids are also included.Los síntomas gastrointestinales en los pacientes con lupus eritematoso sistémico (LES son comunes, específicamente el dolor abdominal. Sin embargo la tasa de enfermedades pancreáticas es mucho menor, una tasa que no alcanza ni al 5% según las series publicadas en Europa y EE. UU. Esta asociación entre enfermedades pancreáticas y LES es fundamentalmente a expensas de episodios de pancreatitis aguda. La asociación con pancreatitis crónica es muchísimo más infrecuente, teniendo en cuenta que tan sólo cuatro artículos han sido publicados reflejando esta asociación. Describimos tres casos de asociación entre pancreatitis y LES, analizando el debut de la enfermedad, los factores etiológicos y también la evolución clínica. Hemos realizado, además, una breve discusión de la fisiopatología y del papel de corticosteroides, así como una revisión de la literatura.

    Contrast computed tomography and magnetic resonance imaging are widely used due to its image quality and ability to study pancreatic and peripancreatic morphology. The understanding of the various subtypes of the disease and identification of possible complications requires a familiarity with the terminology, which allows effective communication between the different members of the multidisciplinary team. Demonstrate the terminology and parameters to identify the different classifications and findings of the disease based on the international consensus for acute pancreatitis ( Atlanta Classification 2012). Search and analysis of articles in the "CAPES Portal de Periódicos with headings "acute pancreatitis" and "Atlanta Review". Were selected 23 articles containing radiological descriptions, management or statistical data related to pathology. Additional statistical data were obtained from Datasus and Population Census 2010. The radiological diagnostic criterion adopted was the Radiology American College system. The "acute pancreatitis - 2012 Rating: Review Atlanta classification and definitions for international consensus" tries to eliminate inconsistency and divergence from the determination of uniformity to the radiological findings, especially the terminology related to fluid collections. More broadly as "pancreatic abscess" and "phlegmon" went into disuse and the evolution of the collection of patient fluids can be described as "acute peripancreatic collections", "acute necrotic collections", "pseudocyst" and "necrosis pancreatic walled or isolated". Computed tomography and magnetic resonance represent the best techniques with sequential images available for diagnosis. Standardization of the terminology is critical and should improve the management of patients with multiple professionals care, risk stratification and adequate treatment.

    Full Text Available RESUMEN:La insuficiencia renal aguda es un sindrome que característicamente cursa con niveles plasmáticos elevados de urea y creatinina. Sin embargo, hay situaciones clínicas en las cuales este sindrome puede cursar con un incremento de la creatininemia sin presentar elevación de la uremia.En este reporte presentamos un caso clínico de una insuficiencia renal aguda con uremia normal secundaria a una pielonefritis aguda en un paciente con riñón único. El paciente presentaba una elevada excreción fraccional de urea lo cual podía explicar su uremia normal pese a estar cursando una caída del filtrado gomerular. Dicha excreción de urea elevada fue interpretada como secundaria a una diabetes insipida nefrogénica y una alteración en el recirculado intra-renal de la urea ambos producto de la pielonefritis aguda. Concluimos que la pielonefritis aguda en un paciente mono-reno puede presentarse con un patrón de insuficiencia renal aguda con uremia normal. SUMMARYAcute renal failure is a syndrome that usually runs with an increase in creatinine and urea plasma levels. However, there are clinical situations in which this syndrome may run with an increase in plasma creatinine keeping normal the urea one.In this report we present a case of acute renal failure with normal plasma urea level secondary to an acute pyelonephritis in a single kidney patient. The patient had an increased fractional excretion of urea which could explain the normal plasma urea levels found despite of his reduced glomerular filtration. This increased urea excretion state was interpreted as a consequence of the nephrogenic diabetes insipidus and alteration of the intra-renal urea reciclying process that the acute pyelonephritis induced. In conclusion: Acute pyelonephritis in a single kidney patient can appear as a pattern of acute renal failure with normal plasma urea levels.

    Full Text Available RESUMENLa insuficiencia renal aguda es un sindrome que característicamente cursa con niveles plasmáticos elevados de urea y creatinina. Sin embargo, hay situaciones clínicas en las cuales este sindrome puede cursar con un incremento de la creatininemia sin presentar elevación de la uremia. En este reporte presentamos un caso clínico de una insuficiencia renal aguda con uremia normal secundaria a una pielonefritis aguda en un paciente con riñón único. El paciente presentaba una elevada excreción fraccional de urea lo cual podía explicar su uremia normal pese a estar cursando una caída del filtrado gomerular. Dicha excreción de urea elevada fue interpretada como secundaria a una diabetes insipida nefrogénica y una alteración en el recirculado intra-renal de la urea ambos producto de la pielonefritis aguda. Concluimos que la pielonefritis aguda en un paciente mono-reno puede presentarse con un patrón de insuficiencia renal aguda con uremia normal.SUMMARYAcute renal failure is a syndrome that usually runs with an increase in creatinine and urea plasma levels. However, there are clinical situations in which this syndrome may run with an increase in plasma creatinine keeping normal the urea one. In this report we present a case of acute renal failure with normal plasma urea level secondary to an acute pyelonephritis in a single kidney patient. The patient had an increased fractional excretion of urea which could explain the normal plasma urea levels found despite of his reduced glomerular filtration. This increased urea excretion state was interpreted as a consequence of the nephrogenic diabetes insipidus and alteration of the intra-renal urea reciclying process that the acute pyelonephritis induced. In conclusion: Acute pyelonephritis in a single kidney patient can appear as a pattern of acute renal failure with normal plasma urea levels.

    Full Text Available BACKGROUND: Hypothermia is a frequent event in severe acute pancreatitis (AP and its real effects on the normal pancreas have not been well demonstrated. Moreover, neither have its effects on the outcome of acute pancreatitis been fully investigated. One hypothesis is that oxidative stress may be implicated in lesions caused or treated by hypothermia. AIM OF THE STUDY: To investigate the effect of hypothermia in cerulein-induced acute pancreatitis (CIAP in rats and the role played by oxidative stress in this process. METHODS: Male Wistar rats were divided into hypothermic and normothermic groups. Hypothermia was induced with a cold mattress and rectal temperature was kept at 30ºC for one hour. Acute pancreatitis was induced with 2 doses of cerulein (20 ìg/kg administered at a one-hour interval. Serum amylase, pancreas vascular permeability by Evan's blue method, pancreas wet-to-dry weight ratio and histopathology were analyzed in each group. RESULTS: When compared with normothermic rats, hypothermic animals, with cerulein-induced acute pancreatitis, showed higher levels of pancreatic vascular permeability (p BACKGROUND: Hipotermia é um evento freqüente em episódios de pancreatite aguda, contudo seu efeito real sobre pâncreas normal ainda não esta bem demonstrado. Além do mais, o efeito da hipotermia no decorrer da pancreatite aguda também não está completamente esclarecido. Uma das hipóteses sobre as causas das lesões causadas ou tratadas por hipotermia aventa a implicação de estresse oxidativo. OBJETIVOS: Investigar o efeito da hipotermia em ratos com pancreatite aguda induzida por ceruleína e o papel do estresse oxidativo neste processo. MÉTODOS: Ratos Wistar machos foram divididos em grupos hipotérmicos e normotérmicos. Hipotermia foi induzida com uma bolsa gelada de forma que a temperatura retal permanecesse em 30ºC por uma hora. Pancreatite aguda foi induzida com duas aplicações de ceruleína (20 ìg/kg administradas

    Full Text Available INTRODUCCIÓN. El neumotórax espontáneo simple es causado, en general, por la rotura de una pequeña zona debilitada del pulmón. Un neumotórax recidivante puede causar una incapacidad considerable. MÉTODOS. Se realizó un estudio descriptivo, prospectivo, de corte transversal de los pacientes con neumotórax persistente y recidivante, atendidos en el Hospital Universitario «Comandante Manuel Fajardo» en el período de 1988 a 2006. Se analizaron las causas del neumotórax y los resultados de su tratamiento. El universo de estudio fueron todos los pacientes con diagnóstico de neumotórax (225 pacientes, entre los cuales se seleccionó a los diagnosticados de neumotórax persistente o recidivante (42 en total. Todos los pacientes fueron atendidos siguiendo un algoritmo de trabajo del servicio de cirugía del hospital. RESULTADOS. Las bullas fueron la causa fundamental en el neumotórax recidivante y las vesículas subpleurales, en los persistentes. En los neumotórax persistentes se mantuvo la sonda de aspiración hasta el quinto día en el 71 % de los casos, hasta 5 a 7 días en el 23 % y por más de 7 días en el 6 %. Se utilizó la vía axilar para la incisión y se realizó resección atípica o reglada con pleurectomía parietal o abrasión, que tuvo un 100 % de efectividad. La mortalidad quirúrgica fue nula. CONCLUSIONES. Los cuidados de la sonda de pleurotomía y la aspiración continua controlada son pilares en el tratamiento primario del neumotórax. Después de 5 días sin lograr la reexpansión pulmonar y si existe un segundo neumotórax, debe siempre valorarse el tratamiento definitivo por toracotomía. Debe considerarse la pleurectomía parietal como el proceder de elección en los pacientes con reserva cardiorrespiratoria adecuada. Un buen sistema de aspiración de drenaje hace que no sea necesaria una segunda intervención y disminuye las posibilidades de complicacionesINTRODUCTION. The simple spontaneous pneumothorax is

OBJETIVO: Descrever e avaliar as características bioquímicas e histológicas da pancreatite aguda induzida pela L-arginina em ratos durante a instalação, desenvolvimento e reparação do processo inflamatório pancreático. MATERIAL E MÉTODOS: A amostra constituiu-se de 105 ratos machos, da linhagem Wistar. Aos ratos do grupo experimento (n = 70 administrou-se injeção intraperitonial de 500 mg/100 g de peso corporal de L-arginina. No grupo controle (n = 35 foi injetada solução salina isotônica. Analisaram-se 10 animais do grupo experimento e 5 do grupo controle em cada período de 6 h, 12 h, 24 h, 48 h, 72 h, 7 dias e 14 dias. Durante os tempos determinados coletou-se sangue para exames laboratoriais e o pâncreas para análise em microscopia óptica. RESULTADOS: Doze a 24 horas após a injeção de L-arginina os níveis séricos de amilase atingiram valores máximos, comparados àqueles dos ratos controle, decrescendo gradualmente, alcançou-os na 48ªhora sendo significativamente menor após 72 horas e 7 dias. A atividade enzimática retornou a níveis basais após 14 dias. Os valores de amilase estavam normais em todos os tempos avaliados nos animais do grupo controle. Na microscopia óptica, após injeção de L-arginina, observou-se arquitetura pancreática histologicamente preservada no período de 6 horas, evidenciando-se em 24 horas importante edema intersticial. Após 48 horas, a arquitetura acinar estava parcialmente destruída com necrose celular focal, atingindo sua máxima severidade ao ultrapassar 72 horas. No 7º dia a necrose tecidual e o edema haviam diminuído, iniciando-se a regeneração da arquitetura acinar. Observou-se a reconstrução estrutural pancreática após 14 dias. No grupo controle não se encontraram alterações histológicas pancreáticas. CONCLUSÃO: A pancreatite aguda experimental

    Full Text Available Resumen La disfunción del esfínter de Oddi es una patología poco frecuente que es causa de aproximadamente el 20% de las pancreatitis recurrentes idiopáticas. Para sospechar de su existencia es obligatorio haber descartado todas las otras causas de pancreatitis aguda. Luego, sobre la base de la historia clínica, exámenes de laboratorio y estudio con imágenes, se debe realizar una clasificación del tipo de disfunción. Según ello, es necesario llevar a cabo una manometría, considerada el gold estándar para el diagnóstico, y guiar el método de tratamiento, siendo el de elección la esfinterotomía endoscópica. En el presente artículo se discute un caso de pancreatitis recurrente, que luego de un minucioso estudio, y habiendo descartado otras etiologías, se diagnosticó como causa la disfunción del esfínter de Oddi tipo pancreática. Se resolvió mediante esfinterotomía endoscópica, presentando una evolución favorable y sin recurrencia de la sintomatología.

    Full Text Available PURPOSE: To compare the effect of parenteral versus enteral nutritional support in severe acute pancreatitis, with respect to efficacy, safety, morbidity, mortality and length of hospitalization. METHODS: The study was comprised of 31 patients, divided into a parenteral group (n=16 and an enteral group (n=15, who met severity criteria for abdominal tomography (Balthazar classes C, D, and E. The patients were compared by demographics, disease etiology, antibiotic prophylaxis, use or not of somatostatin, nutritional support, complications and disease progression. RESULTS: There was no statistical difference in the average duration of nutritional support, somatostatin, or antibiotics in the two groups. Imipenem was the drug of choice for prophylaxis of pancreatic infections in both groups. More complications occurred in the parenteral group, although the difference was not statistically significant (p=0.10. Infectious complications, such as catheter sepsis and infections of the pancreatic tissue, were significantly more frequent in the parenteral group (p=0.006. There was no difference in average length of hospitalization in the two groups. There were three deaths in the parenteral group and none in the enteral group.

    Full Text Available BACKGROUND: The standard treatment for acute pancreatitis (AP is still based on supportive care. The search for a new drug that could change the natural history of the disease is a continuing challenge for many researchers. The aim of this study is to evaluate the effect of a cyclooxygenase-2 (COX-2 inhibitor on experimental AP in rats. METHODS: The animals were divided into 2 groups: Group 1 (n = 30-animals with taurocholate-induced AP treated with parecoxib (40 mg/kg. Group 2 (n = 30-animals with taurocholate-induced AP that received saline. The COX-2 inhibitor (parecoxib was injected immediately after AP induction, through the penis dorsal vein. The parameters evaluated were histology, serum levels of amylase, IL-6 and IL-10, and mortality rate. RESULTS: The serum levels of IL-6 and IL-10 in the parecoxib-treated group were lower than the control group. The amylase serum levels and the mortality rate remained unchanged in the treated animals. Histologic morphology also was unaltered, except for fat necrosis, which was higher in parecoxib-treated rats. CONCLUSION: Inhibition of Cox-2 decreases the systemic release of inflammatory cytokines, but has a poor effect on the direct pancreas injury caused by taurocholate.INTRODUÇÃO: O tratamento padrão para a pancreatite aguda permanece baseado em medidas de suporte. A busca por uma droga que altere a história natural da doença ainda é um desafio para muitos pesquisadores.

Se logró mejoría clínica, normalidad de sus enzimas en una semana, no hubo complicaciones, tuvo evolución posoperatoria satisfactoria, y una estadía hospitalaria de 14 días. Actualmente se mantiene con 4 años de evolución satisfactoria. La técnica efectuada en el paciente es considerada por muchos como la ideal, por su baja incidencia de mortalidad (menos del 3 % y por el alivio del dolor en más del 75 % de los pacientes. Por ello, se considera que esta técnica quirúrgica pudiera ser una opción terapéutica eficaz para este tipo de paciente.

    Full Text Available As principais causas de inflamação pancreática no mundo são a litíase biliar e o alcoolismo crônico. Admite-se que 10 a 30% das pancreatites agudas sejam idiopáticas. Sugere-se que parte destas são causadas por microlitíase ou barro biliar, identificados pela presença de microcristais no sedimento biliar. Neste estudo, realizou-se análise microscópica da bile obtida por colangiopancreatografia endoscópica, em pacientes com pancreatite aguda idiopática, pancreatite aguda biliar e pancreatite crônica alcoólica - 20 em cada grupo. Pacientes com pancreatite aguda idiopática e microcristais na bile foram submetidos a colecistectomia. Naqueles inaptos à cirurgia efetuou-se esfincterotomia endoscópica ou tratamento com ácido ursodesoxicólico. Pacientes com pancreatite aguda idiopática sem cristais não receberam tratamento específico. A prevalência de microcristais biliares em pacientes com pancreatite aguda idiopática (75% e pancreatite aguda biliar (90% foi significativamente maior que naqueles com pancreatite crônica alcoólica (15%. A detecção de microcristais apresentou sensibilidade de 90%, especificidade de 85%, valor preditivo positivo de 85,7%, valor preditivo negativo de 89,4% e acurácia de 87,5% em identificar pancreatite de origem biliar. Nos pacientes com pancreatite aguda idiopática recurrente, cursando com microcristais, houve redução significante dos episódios de pancreatite após tratamento específico. No seguimento deste grupo durante 23,3 meses, recidiva ocorreu apenas naqueles que apresentavam "fator biliar persistente" (coledocolitíase ou microcristais. Todos os pacientes com pancreatite aguda idiopática submetidos a colecistectomia apresentavam colecistite crônica, e microlitíase foi observada em um paciente. No seguimento ultra-sonográfico, colelitíase foi detectada em um dos casos. No subgrupo de cinco pacientes com pancreatite aguda idiopática sem microcristais houve uma recidiva. Estudo

    2015-01-01

    Full Text Available Introduction. Pancreatic actinomycosis is a chronic infection of the pancreas caused by the suppurative Gram-positive bacterium Actinomyces. It has mostly been described in patients following repeated main pancreatic duct stenting in the context of chronic pancreatitis or following pancreatic surgery. This type of pancreatitis is often erroneously interpreted as pancreatic malignancy due to the specific invasive characteristics of Actinomyces. Case. A 64-year-old male with a history of chronic pancreatitis and repeated main pancreatic duct stenting presented with weight loss, fever, night sweats, and abdominal pain. CT imaging revealed a mass in the pancreatic tail, invading the surrounding tissue and resulting in splenic vein thrombosis. Resectable pancreatic cancer was suspected, and pancreatic tail resection was performed. Postoperative findings revealed pancreatic actinomycosis instead of neoplasia. Conclusion. Pancreatic actinomycosis is a rare type of infectious pancreatitis that should be included in the differential diagnosis when a pancreatic mass is discovered in a patient with chronic pancreatitis and prior main pancreatic duct stenting. Our case emphasizes the importance of pursuing a histomorphological confirmation.

    Full Text Available La apendicitis aguda en los niños, presenta actitudes particulares que diferencian de la apendicitis aguda del adulto y que vienen a formar grupos clínicos casi exclusivamente de la infancia. De una manera general, las formas más graves, las formas fulminantes de la apendicitis aguda se encuentran especialmente en la infancia y en estas formas graves llama poderosamente la atención, la falta de relación entre los signos clínicos observados y la importancia de las lesiones encontradas en el apéndice y el peritoneo, pues en los niños con signos de intensidad media y sin que se hayan presentado los síntomas que en el adulto caracterizan las formas graves de apendicitis, podemos encontrar en las operaciones practicadas en las primeras 24 a 36 horas, peritonitis generalizadas, formas de apendicitis gangrenosas, que no son frecuentes en el adulto y mucho menos en un lapso de tiempo tan corto.

Nosso objetivo foi avaliar o estado oxidante/antioxidante de crianças com bronquiolite aguda por meio de mensuração da capacidade antioxidante total do plasma, estado oxidante total e índice de estresse oxidativo. MÉTODOS: As crianças com bronquiolite aguda encaminhadas para o Departamento de Emergência Pediátrica do hospital universitário entre janeiro e abril 2012 foram comparadas a controles saudáveis de mesma idade. Os pacientes com bronquiolite aguda tiveram essa doença classificada como leve e moderada. O estado oxidante e antioxidante foi avaliado pela mensuração da capacidade antioxidante total do plasma, estado oxidante total e índice de estresse oxidativo. RESULTADOS: Foram incluídas 31 crianças com bronquiolite aguda com idade de três meses a dois anos e 37 crianças saudáveis. O estado oxidante total (EOT foi maior em pacientes com bronquiolite aguda do que no grupo de controle (5,16±1,99 µmol H2O2 em comparação a 3,78±1,78 µmol H2O2 [p = 0,004].

    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.

    Full Text Available A lesão pulmonar aguda e sua forma mais grave, a síndrome da angústia respiratória aguda, são o denominador comum de várias doenças que podem provocar uma inflamação exagerada nos pulmões. Nos últimos anos, essa variabilidade tem sido atribuída, pelo menos em parte, a fatores genéticos. O presente estudo tem por objetivos revisar o papel dos principais genes envolvidos na suscetibilidade, morbidade e mortalidade na lesão pulmonar aguda e na síndrome da angústia respiratória aguda. Através de pesquisa nas bases de dados PubMed e LiLACS, empregando-se os unitermos lesão pulmonar aguda, síndrome da angústia respiratória aguda e síndrome da angústia respiratória do adulto em combinação com polimorfismos genéticos, foram selecionados 69 artigos, dos quais 38 foram incluídos nesta revisão. Foram também considerados artigos relevantes extraídos das referências bibliográficas nos artigos selecionados das bases de dados. Os polimorfismos genéticos são variantes gênicas presentes em pelo menos 1% da população. A presença destas variantes genéticas pode influenciar a expressão de mediadores da resposta inflamatória, afetando diretamente a suscetibilidade à lesão pulmonar aguda, a intensidade da inflamação no parênquima pulmonar, a evolução e o desfecho destes pacientes. Estudos de associação com grandes populações e passíveis de reprodução permitirão de modo definitivo a inclusão da genômica no arsenal diagnóstico, prognóstico e terapêutico de pacientes com lesão pulmonar aguda/síndrome da angústia respiratória agudaAcute lung injury and its most severe presentation, acute respiratory distress syndrome, are a common denominator for several diseases which can lead to exaggerated lung inflammation. In the last years this variability has been ascribed, at least partially, to genetic issues. This study aims to review the role of the main genes involved in acute lung injury and acute respiratory

Su incidencia e patogénesis se desconoce. Pacientes y métodos: se analizaron retrospectivamente 11 pacientes con esofagitis necrosante aguda desde el punto de vista de los datos clínicos, de laboratorio y endoscopicos en 2 años. Resultados: se analizaron las endoscopias realizadas a 3.976 pacientes, observándose esofagitis necrosante aguda en 11 pacientes. El estado nutricional era malo en 6 pacientes. La resolución completa de la esofagitis se observó en cuatro pacientes. Durante el seguimiento se observó una estenosis en un paciente y un nuevo episodio de esofagitis necrosante aguda en otro paciente. Siete pacientes fallecieron, pero esta elevada mortalidad parece deberse a las enfermedades de base y no es atribuible a las lesiones de la esofagitis necrosante. Conclusiones: la incidencia de esofagitis necrosante aguda en nuestra serie fue 0,28%. La esofagitis necrosante aguda tiene una elevada mortalidad.Background: acute esophageal necrosis has been considered a rare event.

    Full Text Available Introduction Among the organs of internal secretion pancreas has a special place thanks to active exocrine function and a wide range of physiological actions of produced hormones. Violations of endocrine pancreas arises in 6.5-38 % of patients with acute pancreatitis. However, there is still no clear understanding of the pathogenetic mechanisms of hormonal dysfunction of the pancreas in acute pancreatitis, there is no uniform algorithms for its correction. Aim of the research was to study the endocrine function of pancreas in acute pancreatitis. To define the role of endocrine pancreatic function in the etiology and pathogenesis of the acute pancreatitis. To assess the prospects of the use of pancreatic hormones in the treatment and predicting the outcomes of acute pancreatitis. Materials and methods of the research Survey of publications in specialized periodical medical journals, PubMed sources developed by the National Center for Biotechnology Information. Search in PubMed was carried out in the following databases: MEDLINE, Pre MEDLINE. Results of the research. In a significant proportion of patients who recovered from acute pancreatitis, exocrine and endocrine functional impairments were found. This finding was not detected only in patients after severe acute pancreatitis. Routine evaluation of pancreatic function after acute pancreatitis should be considered. The comparative analysis of the synthetic analogues (somatostatin, calcitonin, leu-enkefalin-dalargin influence on the glucose metabolism of rats in acute pancreatitis of was made. Physiological reaction of beta-cells is preserved in infusion of somatostatin. However, infusion of calcitonin results in the distortion of counterregulatory action of insulin and glucagon. It was detected that pancreatic renin-angiotensin system is markedly activated in the experimental rat models of chronic hypoxia and acute pancreatitis.

    Full Text Available INTRODUÇÃO: A pancreatite necro-hemorrágica representa a variante mais grave do espectro de apresentações clínicas que podem compor o quadro da pancreatite aguda. Embora já conhecida há muitos séculos, inúmeras questões permanecem em aberto acerca dessa entidade e o número de trabalhos sobre o assunto publicados nos últimos anos tem sido muito expressivo. MÉTODO: Foi realizada ampla pesquisa na literatura, com especial atenção aos artigos publicados nos últimos três anos e indexados ao PubMed. Foram utilizados os seguintes descritores de forma cruzada: pancreatitis, surgical procedures; necrosis. A pesquisa inicial evidenciou cerca de 13.000 artigos, sendo avaliados os mais relevantes dos últimos três anos além de artigos mais antigos, considerados "clássicos" sobre o assunto e que, portanto, não poderiam deixar de ser citados. CONCLUSÃO: O tratamento da pancreatite aguda envolve um grande número de questões, dentre as quais as mais importantes estão relacionadas ao manejo da antibioticoterapia, tipo de dieta empregada e as questões relacionadas ao manejo da necrose infectada. Em especial, mudanças radicais foram implementadas nos últimos anos sobre todos esses tópicos, e uma atualização constante deve ser obrigatoriamente buscada pelos profissionais envolvidos no tratamento dessa doença.BACKGROUND: Necrotizing pancreatitis represents the most severe form of presentation from the clinical spectra of acute pancreatitis.

    Full Text Available PURPOSE: To investigate the effect of ACE inhibitor, lisinopril and AT1 blocker, losartan, on the obstructive pancreatitis in rat. METHODS: Acute pancreatitis in rats (n=21 was induced for a common hepatic duct were ligated proximal to its entry into the pancreas and the common bile - pancreatic duct were also ligated near its junction with the duodenum, under ether anesthesia, after which the abdomen were closed. The animals was divided in tree groups, being two treated and control group. The animals was treated with Losartan and Lisinopril at the dose of 10µg/Kg body weight per day, i.p., in a proportional volume, for five days, before and after treatement. RESULTS: The inflammation, collagen deposition in the pancreas of treated animals were smaller, suggesting that the use of antihypertensive agents interfered positively in the depletion of the injury of the pancreas. Scythe showed a correlation between activity of pancreatic stellate cells (PSCs lower in treated animals when compared to control. CONCLUSION: The pancreatic stellate cells strength are involved in collagen production during acute pancreatitis and why antihypertensive drugs such as lisinopril and losartan may possibly have beneficial effects in reducing pancreatic fibrosis in models of experimental obstructive pancreatitis.OBJETIVO: Investigar o efeito de um inibidor da ECA, lisinopril e bloqueador AT1, losartan, a pancreatite obstrutiva em ratos.

    Full Text Available Introducción: las colecciones agudas o crónicas del pericardio con frecuencia producen una compresión del corazón que en los casos crónicos conlleva invalidez y, en los agudos, peligro de muerte por taponamiento cardíaco. Objetivo: caracterizar a los pacientes intervenidos quirúrgicamente en el Hospital Universitario "Comandante Manuel Fajardo" entre 1995 y 2012 a causa de colecciones pericárdicas. Métodos: se realizó un estudio descriptivo transversal con los pacientes atendidos quirúrgicamente en dicha institución por colecciones del pericardio. Constituyeron el universo 24 pacientes: 22 con colecciones agudas y 2 con colecciones crónicas. Resultados: la causa más frecuente de los derrames agudos fue la pericarditis aguda idiopática (25 %. Las colecciones crónicas fueron por pericarditis fibrosa de causa idiopática en el 100 % de los enfermos. La intervención realizada fue la resección del pericardio y el drenaje de las colecciones agudas mediante toracotomía izquierda o por vía preperitoneal subxifoidea. En las colecciones de origen maligno se realizó la resección pericárdica con fines paliativos y, en los derrames por lesión traumática del corazón, la sutura de este órgano fue el tratamiento quirúrgico empleado en todos los casos. En las pericarditis constrictivas, la pericardiectomía radical fue el tratamiento empleado en el 100 % de los casos. Conclusiones: el tratamiento quirúrgico en las colecciones agudas y crónicas del pericardio permite drenar el contenido por una ventana pericárdica obtenida por toracoscopia o por vía preperitoneal subxifoidea, mientras que la toracotomía izquierda es útil en las emergencias. En los derrames crónicos con fibrosis y síntomas de insuficiencia cardíaca, la pericardiectomía radical mediante esternotomía media ofrece los mejores resultados.

    Acute pancreatitis is one of the most frequent gastrointestinal causes for hospital admission in the US. Chronic pancreatitis, although lower in incidence, significantly reduces patients’ quality of life. Pancreatic cancer has high mortality and is 1 of the top 5 causes of death from cancer. The burden of pancreatic disorders is expected to increase over time. The risk and etiology of pancreatitis differ with age and sex, and all pancreatic disorders affect Blacks more than any other race. Gallstones are the most common cause of acute pancreatitis, and early cholecystectomy eliminates the risk of future attacks. Alcohol continues to be the single most important risk factor for chronic pancreatitis. Smoking is an independent risk factor for acute and chronic pancreatitis, and its effects could synergize with those of alcohol. Significant risk factors for pancreatic cancer include smoking and non-O blood groups. Alcohol abstinence and smoking cessation can alter progression of pancreatitis and reduce recurrence; smoking cessation is the most effective strategy to reduce the risk of pancreatic cancer.

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

    Full Text Available De acordo com a Classificação de Atlanta a pancreatite aguda pode ser dividida, baseado em sua severidade, em uma forma leve ou grave. Uma série de aspectos têm sido discutidos nos últimos anos, tais como, quantas categorias de gravidade devem ser consideradas; se o doente com falência orgânica é igual ao doente com necrose infectada; qual o papel da falência orgânica transitória; e como avaliar a falência orgânica. A reunião de revista"Telemedicina Baseada em Evidência - Cirurgia do Trauma e Emergência" (TBE-CiTE realizou uma avaliação crítica de artigos relacionados a este tema, considerando três artigos recentes que delinearam duas grandes revisões publicadas nos últimos meses. Estes artigos sugerem a classificação de gravidade em três ou quatro categorias, ao invés de pancreatite aguda leve ou grave, além de discutir qual o melhor escore para avaliar a falência orgânica. As seguintes recomendações foram propostas: (1 A pancreatite aguda deve ser classificada em quatro categorias: leve, moderada, grave e crítica, o que permite uma melhor determinação das características dos doentes; (2 Avaliação de falência orgânica com um escore de gravidade, preferencialmente algum que avalie diretamente cada falência orgânica, tais como o SOFA e o MODS (Marshall.

  18. Autoimmune pancreatitis can develop into chronic pancreatitis

    Science.gov (United States)

    2014-01-01

    Autoimmune pancreatitis (AIP) has been recognized as a distinct type of pancreatitis that is possibly caused by autoimmune mechanisms. AIP is characterized by high serum IgG4 and IgG4-positive plasma cell infiltration in affected pancreatic tissue. Acute phase AIP responds favorably to corticosteroid therapy and results in the amelioration of clinical findings. However, the long-term prognosis and outcome of AIP remain unclear. We have proposed a working hypothesis that AIP can develop into ordinary chronic pancreatitis resembling alcoholic pancreatitis over a long-term course based on several clinical findings, most notably frequent pancreatic stone formation. In this review article, we describe a series of study results to confirm our hypothesis and clarify that: 1) pancreatic calcification in AIP is closely associated with disease recurrence; 2) advanced stage AIP might have earlier been included in ordinary chronic pancreatitis; 3) approximately 40% of AIP patients experience pancreatic stone formation over a long-term course, for which a primary risk factor is narrowing of both Wirsung’s and Santorini’s ducts; and 4) nearly 20% of AIP patients progress to confirmed chronic pancreatitis according to the revised Japanese Clinical Diagnostic Criteria, with independent risk factors being pancreatic head swelling and non-narrowing of the pancreatic body duct.

    Full Text Available Abstract: Cancer patients experience weight loss for a variety of reasons, commencing with the tumor’s metabolism (Warburg effect and proceeding via cachexia to loss of appetite. In pancreatic cancer, several other factors are involved, including a loss of appetite with a particular aversion to meat and the incapacity of the pancreatic gland to function normally when a tumor is present in the pancreatic head. Pancreatic exocrine insufficiency is characterized by a deficiency of the enzymes secreted from the pancreas due to the obstructive tumor, resulting in maldigestion. This, in turn, contributes to malnutrition, specifically a lack of fat-soluble vitamins, antioxidants, and other micronutrients. Patients with pancreatic cancer and pancreatic exocrine insufficiency have, overall, an extremely poor prognosis with regard to surgical outcome and overall survival. Therefore, it is crucial to be aware of the mechanisms involved in the disease, to be able to diagnose pancreatic exocrine insufficiency early on, and to treat malnutrition appropriately, for example, with pancreatic enzymes.

    To improve the diagnostic accuracy of pancreatic carcinoma and chronic pancreatitis. The CT findings of 154 cases with pancreatic carcinoma, chronic pancreatitis and mis-diagnosed other pancreatic diseases proven clinically and pathologically were analysed. Slice thickness of 8 mm and slice interval of 8 mm were used and thin-section scan and enhancement study were performed in some cases. The main signs in degassing and differential diagnosis between pancreatic carcinoma and chronic pancreatitis included: (1) focal or diffuse enlargement and density abnormality of pancreas; (2) dilated common bile duct was suddenly obstructed, peripancreatic blood vessels were invaded and cancerous thrombus was revealed, enlargement of abdominal lymph nodes and metastasis in the liver were discovered; (3) calcium deposit in the pancreatic duct area and dilated pancreatic duct which passed through the lesion or not; (4) presence and location of pancreatic cyst and its relationship to pancreatic contour. CT is the imaging modality of choice in the diagnosis of pancreatic carcinoma and chronic pancreatitis at present. The diagnostic accuracy of CT was over 90% in this series

    Obstruction of the pancreatic duct can lead to pancreatic fibrosis. We investigated the correlation between the extent of pancreatic fibrosis and the postoperative exocrine and endocrine pancreatic function. Fifty-five patients who were treated for pancreatic and periampullary carcinoma and 19 patients with chronic pancreatitis were evaluated. Exocrine pancreatic function was evaluated by fecal elastase-1 test, while endocrine pancreatic function was assessed by plasma glucose level. The extent of fibrosis, duct dilation and endocrine tissue loss was examined histopathologically. A strong correlation was found between pancreatic fibrosis and elastase-1 level less than 100 microg/g (p pancreatic insufficiency. A strong correlation was found between pancreatic fibrosis and endocrine tissue loss (p pancreatic fibrosis nor endocrine tissue loss were correlated with the development of postoperative diabetes mellitus. Duct dilation alone was neither correlated with exocrine nor with endocrine function loss. The majority of patients develop severe exocrine pancreatic insufficiency after pancreatoduodenectomy. The extent of exocrine pancreatic insufficiency is strongly correlated with preoperative fibrosis. The loss of endocrine tissue does not correlate with postoperative diabetes mellitus. Preoperative dilation of the pancreatic duct per se does not predict exocrine or endocrine pancreatic insufficiency postoperatively. Copyright 2008 S. Karger AG, Basel.

    Chronic pancreatitis is a debilitating condition often associated with severe abdominal pain and exocrine and endocrine dysfunction. The underlying cause is multifactorial and involves complex interaction of environmental, genetic, and/or other risk factors. The pathology is dependent on the underlying pathogenesis of the disease. This review describes the clinical, gross, and microscopic findings of the main subtypes of chronic pancreatitis: alcoholic chronic pancreatitis, obstructive chronic pancreatitis, paraduodenal ("groove") pancreatitis, pancreatic divisum, autoimmune pancreatitis, and genetic factors associated with chronic pancreatitis. As pancreatic ductal adenocarcinoma may be confused with chronic pancreatitis, the main distinguishing features between these 2 diseases are discussed. Copyright © 2016 Elsevier Inc.

    Full Text Available Inflammation is part of the body’s immune response in order to remove harmful stimuli – like pathogens, irritants or damaged cells - and start the healing process. Recurrent or chronic inflammation on the other side seems a predisposing factor for carcinogenesis and has been found associated with cancer development. In chronic pancreatitis mutations of the cationic trypsinogen (PRSS1 gene have been identified as risk factors of the disease. Hereditary pancreatitis is a rare cause of chronic pancreatic inflammation with an early onset, mostly during childhood. Hereditary pancreatitis often starts with recurrent episodes of acute pancreatitis and the clinical phenotype is not very much different from other etiologies of the disease. The long-lasting inflammation however generates a tumor promoting environment and represents a major risk factor for tumor development This review will reflect our knowledge concerning the specific risk of hereditary pancreatitis patients to develop pancreatic cancer.

    Full Text Available A carambola pertence à família das Oxalidáceas, espécie Averrhoa carambola. É rica em sais minerais, vitaminas A, C, complexo B e ácido oxálico. Estudos recentes demonstram que a toxicidade da fruta difere entre os indivíduos e pode ser explicada pelas respostas biológicas individuais como idade, quantidade da ingestão, neurotoxinas em cada tipo de fruta. Adicionalmente, a nefrotoxicidade causada pela fruta é dose dependente, podendo levar ao desenvolvimento de lesão renal aguda pela deposição de cristais de oxalato de cálcio intratubular, assim como por lesão direta das células epiteliais tubulares, levando à apoptose das mesmas. Relatamos o caso de uma paciente que, após a ingestão do suco da fruta e fruta in natura, desenvolveu lesão renal aguda, necessitando de terapia dialítica, evoluindo com desfecho favorável e recuperação da função renal.

    Full Text Available A pancreatite aguda tem sido alvo de grandes discussões que vão desde o entendimento de sua fisiopatologia até a investigação de novas modalidades terapêuticas. Reconhece-se que a necrose pancreática e a falência orgânica múltipla - mormente associadas à infecção - representam os principais fatores determinantes da evolução para o óbito, mas, apesar dos grandes avanços em seu estudo, a doença permanece como um desafio para o clínico e o cirurgião. Deste modo, um melhor conhecimento dos mecanismos envolvidos em sua fisiopatologia pode ser a chave para um tratamento mais eficaz, principalmente em relação às formas graves, cuja letalidade ainda encontra-se substancialmente elevada. Baseado nestas considerações, o presente trabalho tem por objetivo a revisão bibliográfica da fisiopatologia, dos fatores patogênicos envolvidos na história natural da pancreatite aguda grave e dos eventos associados à síndrome da resposta inflamatória sistêmica e à sepse, esboçando-se assim o mosaico patogênico desta importante condição.

    One of the diseases involving a potential risk of developing chronic pancreatitis is acute pancreatitis. Of the overall number of 231 individuals followed with a diagnosis of chronic pancreatitis, 56 patients were initially treated for acute pancreatitis (24.2 %). Within an interval of 12- 24 months from the first attack of acute pancreatitis, their condition gradually progressed to reached the picture of chronic pancreatitis. The individuals included in the study abstained (from alcohol) following the first attack of acute pancreatitis and no relapse of acute pancreatitis was proven during the period of their monitoring. The etiology of acute pancreatitis identified alcohol as the predominant cause (55.3 %), biliary etiology was proven in 35.7 %. According to the revised Atlanta classification, severe pancreatitis was established in 69.6 % of the patients, the others met the criterion for intermediate form, those with the light form were not included. Significant risk factors present among the patients were smoking, obesity and 18 %, resp. 25.8 % had pancreatogenous diabetes mellitus identified. 88.1 % of the patients with acute pancreatitis were smokers. The majority of individuals with chronic pancreatitis following an attack of acute pancreatitis were of a productive age from 25 to 50 years. It is not only acute alcoholic pancreatitis which evolves into chronic pancreatitis, we have also identified this transition for pancreatitis of biliary etiology.

    Pancreatic and peripancreatic fluid collections may develop after severe acute pancreatitis. Organized fluid collections such as pancreatic pseudocyst and walled-off pancreatic necrosis (WOPN) that mature over time may require intervention to treat obstructive or constitutional symptoms related to the size and location of the collection as well as possible infection. Endoscopic, open surgical and minimally invasive techniques are described to treat post-inflammatory pancreatic fluid collections. Surgical intervention may be required to treat collections containing necrotic pancreatic parenchyma or in locations not immediately apposed to the stomach or duodenum. Comprising a blend of the surgical approach and the clinical benefits of minimally invasive surgery, the robot-assisted technique of pancreatic cystgastrostomy with pancreatic debridement is described.

    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.

    An important question in systems biology is what role the underlying molecular mechanisms play in disease progression. The relationship between chronic pancreatitis and pancreatic cancer needs further exploration in a system view. We constructed the disease network based on gene expression data and protein-protein interaction. We proposed an approach to discover the underlying core network and molecular factors in the progression of pancreatic diseases, which contain stages of chronic pancreatitis and pancreatic cancer. The chronic pancreatitis and pancreatic cancer core network and key factors were revealed and then verified by gene set enrichment analysis of pathways and diseases. The key factors provide the microenvironment for tumor initiation and the change of gene expression level of key factors bridge chronic pancreatitis and pancreatic cancer. Some new candidate genes need further verification by experiments. Transcriptome profiling-based network analysis reveals the importance of chronic pancreatitis genes and pathways in pancreatic cancer development on a system level by computational method and they can be therapeutic targets.

    Pancreatic trauma occurs in approximately 4% of all patients sustaining abdominal injuries. The pancreas has an intimate relationship with the major upper abdominal vessels, and there is significant morbidity and mortality associated with severe pancreatic injury. Immediate resuscitation and investigations are essential to delineate the nature of the injury, and to plan further management. If main pancreatic duct injuries are identified, specialised input from a tertiary hepatopancreaticobiliary (HPB) team is advised. A comprehensive online literature search was performed using PubMed. Relevant articles from international journals were selected. The search terms used were: 'pancreatic trauma', 'pancreatic duct injury', 'radiology AND pancreas injury', 'diagnosis of pancreatic trauma', and 'management AND surgery'. Articles that were not published in English were excluded. All articles used were selected on relevance to this review and read by both authors. Pancreatic trauma is rare and associated with injury to other upper abdominal viscera. Patients present with non-specific abdominal findings and serum amylase is of little use in diagnosis. Computed tomography is effective in diagnosing pancreatic injury but not duct disruption, which is most easily seen on endoscopic retrograde cholangiopancreaticography or operative pancreatography. If pancreatic injury is suspected, inspection of the entire pancreas and duodenum is required to ensure full evaluation at laparotomy. The operative management of pancreatic injury depends on the grade of injury found at laparotomy. The most important prognostic factor is main duct disruption and, if found, reconstructive options should be determined by an experienced HPB surgeon. The diagnosis of pancreatic trauma requires a high index of suspicion and detailed imaging studies. Grading pancreatic injury is important to guide operative management. The most important prognostic factor is pancreatic duct disruption and in these cases

    Full Text Available Background: Autoimmune pancreatitis is a recently described type of pancreatitis of presumed autoimmune etiology. Autoimmune pancreatitis is often misdiagnosed as pancreatic cancer difficult, since their clinical presentations are often similar. The concept of autoimmune pancreatitis was first published in 1961. Since then, autoimmune pancreatitis has often been treated not as an independent clinical entity but rather as a manifestation of systemic disease. The overall prevalence and incidence of the disease have yet to be determined, but three series have reported the prevalence as between 5 and 6 % of all patients with chronic pancreatitis. Patient vary widely in age, but most are older than 50 years. Patients with autoimmune pancreatitis usually complain of the painless jaundice, mild abdominal pain and weight loss. There is no laboratory hallmark of the disease, even if cholestatic profiles of liver dysfunction with only mild elevation of amylase and lipase levels have been reported.Conclusions: Proposed diagnostic criteria contains: (1 radiologic imaging, diffuse enlargement of the pancreas and diffusely irregular narrowing of the main pancreatic duct, (2 laboratory data, elevated levels of serum ã-globulin and/or IgG, specially IgG4, or the presence of autoantibodies and (3 histopathologic examination, fibrotic change with dense lymphoplasmacytic infiltration in the pancreas. For correct diagnosis of autoimmune pancreatitis, criterion 1 must be present with criterion 2 and/or 3. Autoimmune pancreatitis is frequently associated with rheumatoid arthritis, Sjogren’s syndrome, inflammatory bowel disease, tubulointersticial nephritis, primary sclerosing cholangitis and idiopathic retroperitoneal fibrosis. Pancreatic biopsy using an endoscopic ultrasound-guided fine needle aspiration biopsy is the most important diagnostic method today. Treatment with corticosteroids leads to the and resolution of pancreatic inflamation, obstruction and

    This study aimed to investigate the impairment of pancreatic endocrine function and the associated risk factors after acute pancreatitis (AP). Fifty-nine patients were subjected to tests of pancreatic function after an attack of pancreatitis. The mean time after the event was 3.5 years. Pancreatic endocrine function was evaluated by fasting blood glucose (FBG), glycosylated hemoglobin, fasting blood insulin, and C-peptide. Homeostasis model assessment was used to evaluate insulin resistance and islet β-cell function. Pancreatic exocrine function was evaluated by fecal elastase 1. Factors that could influence endocrine function were also investigated. Nineteen patients (32%) were found to have elevated FBG, whereas 5 (8%) had abnormal glycosylated hemoglobin levels. The levels of FBG, fasting blood insulin, and C-peptide were higher in patients than in controls (P endocrine insufficiency. Pancreatic exocrine functional impairment was found at the same time. Endocrine functional impairment with insulin resistance was found in patients after AP. Obesity, hyperlipidemia, and diabetes-related symptoms increased the likelihood of developing functional impairment after AP.

    Acute pancreatitis may be the first manifestation of pancreatic cancer. The aim of this study was to assess the risk of pancreatic cancer after a first episode of acute pancreatitis. Between March 2004 and March 2007, all consecutive patients with a first episode of acute pancreatitis were prospectively registered. Follow-up was based on hospital records audit, radiological imaging, and patient questionnaires. Outcome was stratified based on the development of chronic pancreatitis. We included 731 patients. The median follow-up time was 55 months. Progression to chronic pancreatitis was diagnosed in 51 patients (7.0%). In this group, the incidence rate per 1000 person-years for developing pancreatic cancer was 9.0 (95% confidence interval, 2.3-35.7). In the group of 680 patients who did not develop chronic pancreatitis, the incidence rate per 1000 person-years for developing pancreatic cancer in this group was 1.1 (95% confidence interval, 0.3-3.3). Hence, the rate ratio of pancreatic cancer was almost 9 times higher in patients who developed chronic pancreatitis compared with those who did not (P = 0.049). Although a first episode of acute pancreatitis may be related to pancreatic cancer, this risk is mainly present in patients who progress to chronic pancreatitis.

    Pancreatic ductal calculi are most often associated with chronic pancreatitis. Radiological features of chronic pancreatitis are readily evident in the presence of these calculi. However, acute pancreatitis due to a solitary main pancreatic ductal calculus of biliary origin is rare. A 59-year-old man presented with a first episode of acute pancreatitis. Contrast enhanced computerized tomography (CT) scan and endoscopic retrograde cholangiopancreatography (ERCP) revealed a calculus in the main pancreatic duct in the head of the pancreas causing acute pancreatitis. There were no features suggestive of chronic pancreatitis on CT scanning. The episode acute pancreatitis was managed conservatively. ERCP extraction of the calculus failed as the stone was impacted in the main pancreatic duct resulting in severe acute pancreatitis. Once this resolved, a transduodenal exploration and extraction of the pancreatic ductal calculus was performed successfully. Crystallographic analysis revealed the composition of the calculus was different to that seen in chronic pancreatitis, but more in keeping with a calculus of biliary origin. This could be explained by migration of the biliary calculus via the common channel into the main pancreatic duct. Following the operation the patient made an uneventful recovery and was well at two-year follow up. Acute pancreatitis due to a solitary main pancreatic ductal calculus of biliary origin is rare. Failing endoscopic extraction, transduodenal exploration and extraction is a safe option after resolution of acute pancreatitis.

    Patients with a first episode of acute pancreatitis can develop recurrent or chronic pancreatitis (CP). However, little is known about the incidence or risk factors for these events. We performed a cross-sectional study of 669 patients with a first episode of acute pancreatitis admitted to 15 Dutch hospitals from December 2003 through March 2007. We collected information on disease course, outpatient visits, and hospital readmissions, as well as results from imaging, laboratory, and histology studies. Standardized follow-up questionnaires were sent to all available patients to collect information on hospitalizations and interventions for pancreatic disease, abdominal pain, steatorrhea, diabetes mellitus, medications, and alcohol and tobacco use. Patients were followed up for a median time period of 57 months. Primary end points were recurrent pancreatitis and CP. Risk factors were evaluated using regression analysis. The cumulative risk was assessed using Kaplan-Meier analysis. Recurrent pancreatitis developed in 117 patients (17%), and CP occurred in 51 patients (7.6%). Recurrent pancreatitis developed in 12% of patients with biliary disease, 24% of patients with alcoholic etiology, and 25% of patients with disease of idiopathic or other etiologies; CP occurred in 3%, 16%, and 10% of these patients, respectively. Etiology, smoking, and necrotizing pancreatitis were independent risk factors for recurrent pancreatitis and CP. Acute Physiology and Chronic Health Evaluation II scores at admission also were associated independently with recurrent pancreatitis. The cumulative risk for recurrent pancreatitis over 5 years was highest among smokers at 40% (compared with 13% for nonsmokers). For alcohol abusers and current smokers, the cumulative risks for CP were similar-approximately 18%. In contrast, the cumulative risk of CP increased to 30% in patients who smoked and abused alcohol. Based on a retrospective analysis of patients admitted to Dutch hospitals, a first

    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. Copyright © 2011 S. Karger AG, Basel.

    To summarize recent data on classification systems, cause, risk factors, severity prediction, nutrition, and drug treatment of acute pancreatitis. Comparison of the Revised Atlanta Classification and Determinant Based Classification has shown heterogeneous results. Simvastatin has a protective effect against acute pancreatitis. Young black male, alcohol, smoldering symptoms, and subsequent diagnosis of chronic pancreatitis are risk factors associated with readmissions after acute pancreatitis. A reliable clinical or laboratory marker or a scoring system to predict severity is lacking. The PYTHON trial has shown that oral feeding with on demand nasoenteric tube feeding after 72 h is as good as nasoenteric tube feeding within 24 h in preventing infections in predicted severe acute pancreatitis. Male sex, multiple organ failure, extent of pancreatic necrosis, and heterogeneous collection are factors associated with failure of percutaneous drainage of pancreatic collections. The newly proposed classification systems of acute pancreatitis need to be evaluated more critically. New biomarkers are needed for severity prediction. Further well designed studies are required to assess the type of enteral nutritional formulations for acute pancreatitis. The optimal minimally invasive method or combination to debride the necrotic collections is evolving. There is a great need for a drug to treat the disease early on to prevent morbidity and mortality.

    Circumportal pancreas is a rare congenital pancreatic anomaly with encasement of the portal vein and/or the superior mesenteric vein by pancreatic tissue. It is often overlooked on cross-sectional imaging studies and can be encountered during pancreatic surgery. Pancreatic head resection with circumportal pancreas is technically difficult and bears an increased risk of postoperative pancreatic fistula. A retrospective chart review of our data base for all patients who had undergone pancreatic head resection between 2004 and 2015 was performed. We identified six patients out of 1102 patients who had undergone pancreatic head surgery in the study period. CT-scan and MRI were never able to identify circumportal pancreas prior to surgery. The right hepatic an artery derived from the superior mesenteric artery in four cases (67%). Additional resection of the pancreatic body was always performed. Postoperative course was uneventful in all cases without occurrence of pancreatic fistula. Circumportal pancreas is a rare entity every pancreatic surgeon should be aware of. It is difficult to identify on cross-sectional imaging studies. A right hepatic artery arising from the superior mesenteric artery should raise suspicion of circumportal pancreas. Additional pancreatic tissue resection should be performed during pancreatic head resections to avoid pancreatic fistula.

We searched MEDLINE and EMBASE for observational studies investigating the association between chronic pancreatitis and pancreatic cancer. We computed overall effect estimates (EEs) with associated 95% confidence intervals (CIs) using a random-effects meta-analytic model. The EEs were stratified by length of follow-up from chronic pancreatitis diagnosis to pancreatic cancer (lag period). Robustness of the results was examined in sensitivity analyses. We identified 13 eligible studies. Pooled EEs for pancreatic cancer in patients with chronic pancreatitis were 16.16 (95% CI: 12.59-20.73) for patients diagnosed with pancreatic cancer within 2 years from their chronic pancreatitis diagnosis. The risk of pancreatic cancer in patients with chronic pancreatitis decreased when the lag period was increased to 5 years (EE: 7.90; 95% CI: 4.26-14.66) or a minimum of 9 years (EE: 3.53; 95% CI: 1.69-7.38). In conclusion, chronic pancreatitis increases the risk of pancreatic cancer, but the association diminishes with long-term follow-up. Five years after diagnosis, chronic pancreatitis patients have a nearly eight-fold increased risk of pancreatic cancer. We suggest that common practice on inducing a 2-year lag period in these studies may not be sufficient. We also recommend a close follow-up in the first years following a diagnosis of chronic pancreatitis to avoid overlooking a pancreatic cancer.

    Background & Aims Acute pancreatitis increases morbidity and mortality from organ necrosis by mechanisms that are incompletely understood. Dendritic cells (DCs) can promote or suppress inflammation, depending on their subtype and context. We investigated the roles of DC in development of acute pancreatitis. Methods Acute pancreatitis was induced in CD11c.DTR mice using caerulein or L-arginine; DCs were depleted by administration of diphtheria toxin. Survival was analyzed using Kaplan-Meier analysis. Results Numbers of MHC II+CD11c+DC increased 100-fold in pancreas of mice with acute pancreatitis, to account for nearly 15% of intra-pancreatic leukocytes. Intra-pancreatic DC acquired an immune phenotype in mice with acute pancreatitis; they expressed higher levels of MHC II and CD86 and increased production of interleukin-6, membrane cofactor protein (MCP)-1, and tumor necrosis factor (TNF)-α. However, rather than inducing an organ-destructive inflammatory process, DC were required for pancreatic viability; the exocrine pancreas died in mice that were depleted of DC and challenged with caerulein or L-arginine. All mice with pancreatitis that were depleted of DC died from acinar cell death within 4 days. Depletion of DC from mice with pancreatitis resulted in neutrophil infiltration and increased levels of systemic markers of inflammation. However, the organ necrosis associated with depletion of DC did not require infiltrating neutrophils, activation of NF-κB, or signaling by mitogen-activated protein kinase or TNF-α. Conclusions DC are required for pancreatic viability in mice with acute pancreatitis and might protect organs against cell stress. PMID:21801698

    The purpose of the review was to evaluate the feasibility and outcome of laparoscopic pancreatic cystogastrostomy for operative drainage of symptomatic pancreatic pseudocysts. A retrospective review of all patients who underwent laparoscopic pancreatic cystogastrostomy between June 1997 and July 2001 was performed. Data regarding etiology of pancreatitis, size of pseudocyst, operative time, complications, and pseudocyst recurrence were collected and reported as median values with ranges. Laparoscopic pancreatic cystogastrostomy was attempted in 6 patients. Pseudocyst etiology included gallstone pancreatitis (3), alcohol-induced pancreatitis (2), and post-ERCP pancreatitis (1). The cystogastrostomy was successfully performed laparoscopically in 5 of 6 patients. However, the procedure was converted to open after creation of the cystgastrostomy in 1 of these patients. There were no complications in the cases completed laparoscopically and no deaths in the entire group. No pseudocyst recurrences were observed with a median followup of 44 months (range 4-59 months). Laparoscopic pancreatic cystgastrostomy is a feasible surgical treatment of pancreatic pseudocysts with a resultant low pseudocyst recurrence rate, length of stay, and low morbidity and mortality.

    Chronic pancreatitis (CP) is an irreversible, inflammatory process, which is characterized by progressive fibrosis of the pancreas and leads to abdominal pain, endocrine and exocrine insufficiency. Surgical therapy is indicated by the absence of pain relief and local complications. The target of the surgical approach is to relieve the pancreatic and bile ducts and resection of the fibrotic and calcified parenchyma. Drainage procedures, such as the Partington-Rochelle method, are used in patients with isolated congestion of the pancreatic duct without further organ complications, such as inflammatory processes of the pancreatic head; however, patients with CP often have an inflammatory swelling of the pancreatic head. In this case classical pancreatoduodenectomy (PD) or organ-sparing duodenum-preserving pancreatic head resection (DPPHR) with its various techniques (e.g. Beger, Frey, Bern and V‑shape) can be applied. Due to similar long-term results PD should be carried out in cases of suspicion or detection of malignancies and DPPHR for treatment of CP.

    Pancreatic cancer sometimes occurs during the course of chronic pancreatitis. This study aimed to identify risk factors for developing pancreatic cancer associated with chronic pancreatitis. The incidence of pancreatic cancer developing in 218 patients with chronic pancreatitis and clinical features of the chronic pancreatitis patients who developed pancreatic cancer were studied. Nine patients developed pancreatic cancer. Average period from the diagnosis of chronic pancreatitis to the diagnosis of pancreatic cancer was 9.6 years. All pancreatic cancers were diagnosed at an advanced stage. Only 2 patients had been followed-up periodically. There were no significant differences between chronic pancreatitis patients who developed pancreatic cancer and those who did not in male/female ratio (3.5 vs. 8), average age on diagnosis (65.0 vs. 56.5), alcoholic/non-alcoholic chronic pancreatitis (1.6 vs. 2.6), smoking habits (62.5% vs. 70.7%), diabetes mellitus (77.8% vs. 54.4%), and continued alcohol drinking (37.5% vs. 53.1%). Over the period examined, 4% of chronic pancreatitis patients developed pancreatic cancer. Sex ratio, onset age, etiology, smoking habits, diabetes mellitus, and continued alcohol drinking were not significant risk factors for developing pancreatic cancer in chronic pancreatitis patients. Periodic follow-up due to the possibility of pancreatic cancer is necessary in chronic pancreatitis patients.

    Abnormal pancreatic function tests have been reported to precede the imaging findings of chronic pancreatitis. Magnetic resonance imaging (MRI) with magnetic resonance cholangiopancreatography (MRCP) is increasingly accepted as the primary imaging modality for the detection of structural changes of early mild chronic pancreatitis. The aim of this study was to evaluate MRI/MRCP findings in patients with symptoms consistent with chronic pancreatitis who have normal Secretin Endoscopic Pancreatic Function test. A retrospective study of 32 patients referred for evaluation of chronic abdominal pain consistent with chronic pancreatitis and reported normal standard abdominal imaging (ultrasound, computed tomography, or MRI). All patients underwent Secretin Endoscopic Pancreatic Function testing and pancreatic MRI/MRCP at our institution. We reviewed the MRI/MRCP images in patients who had normal Secretin Endoscopic Pancreatic Function testing. MRI/MRCP images were assessed for pancreatic duct morphology, gland size, parenchymal signal and morphology, and arterial contrast enhancement. Of the 32 patients, 23 had normal Secretin Endoscopic Pancreatic Function testing, and 8 of them had mild to marked spectrum of abnormal MRI/MRCP findings that were predominantly focal. Frequencies of the findings were as follows: pancreatic duct stricture (n=3), pancreatic duct dilatation (n=3), side branch ectasia (n=4), atrophy (n=5), decreased arterial enhancement (n=5), decreased parenchymal signal (n=1), and cavity formation (n=1). The remaining15 patients had normal pancreatic structure on MRI/MRCP. Normal pancreatic function testing cannot exclude abnormal MRI/MRCP especially focal findings of chronic pancreatitis. Further studies needed to verify significance of these findings and establish MRI/MRCP imaging criteria for the diagnosis of chronic pancreatitis.

    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.

    Research highlights: → Recent studies have shown that pancreatic stellate cells (PSCs) promote the progression of pancreatic cancer. → Pancreatic cancer cells co-cultured with PSCs showed loose cell contacts and scattered, fibroblast-like appearance. → PSCs decreased the expression of epithelial markers but increased that of mesenchymal markers, along with increased migration. → This study suggests epithelial-mesenchymal transition as a novel mechanism by which PSCs contribute to the aggressive behavior of pancreatic cancer cells. -- Abstract: The interaction between pancreatic cancer cells and pancreatic stellate cells (PSCs), a major profibrogenic cell type in the pancreas, is receiving increasing attention. There is accumulating evidence that PSCs promote the progression of pancreatic cancer by increasing cancer cell proliferation and invasion as well as by protecting them from radiation- and gemcitabine-induced apoptosis. Because epithelial-mesenchymal transition (EMT) plays a critical role in the progression of pancreatic cancer, we hypothesized that PSCs promote EMT in pancreatic cancer cells. Panc-1 and SUIT-2 pancreatic cancer cells were indirectly co-cultured with human PSCs isolated from patients undergoing operation for pancreatic cancer. The expression of epithelial and mesenchymal markers was examined by real-time PCR and immunofluorescent staining. The migration of pancreatic cancer cells was examined by scratch and two-chamber assays. Pancreatic cancer cells co-cultured with PSCs showed loose cell contacts and a scattered, fibroblast-like appearance. The expression of E-cadherin, cytokeratin 19, and membrane-associated β-catenin was decreased, whereas vimentin and Snail (Snai-1) expression was increased more in cancer cells co-cultured with PSCs than in mono-cultured cells. The migration of pancreatic cancer cells was increased by co-culture with PSCs. The PSC-induced decrease of E-cadherin expression was not altered by treatment with anti

    The main principles of treatment of external postoperative pancreatic fistulas are viewed in the article. Pancreatic trauma was the reason of pancreatic fistula in 38.7% of the cases, operations because of acute pancreatitis - in 25.8%, and pancreatic pseudocyst drainage - in 35.5%. 93 patients recovered after the treatment. Complex conservative treatment of EPF allowed to close fistulas in 74.2% of the patients with normal patency of the main pancreatic duct (MPD). The usage of octreotide 600-900 mcg daily for at least 5 days to decrease pancreatic secretion was an important part of the conservative treatment. Endoscopic papillotomy was performed in patients with major duodenal papilla obstruction and interruption of transporting of pancreatic secretion to duodenum. Stent of the main pancreatic duct was indicated in patients with extended pancreatic duct stenosis to normalize transport of pancreatic secretion to duodenum. Surgical formation of anastomosis between distal part of the main pancreatic duct and gastro-intestinal tract was carried out when it was impossible to fulfill endoscopic stenting of pancreatic duct either because of its interruption and diastasis between its ends, or in the cases of unsuccessful conservative treatment of external pancreatic fistula caused by drainage of pseudocyst.

    2017-03-01

    Full Text Available Eosinophilic pancreatitis is a rare form of recurrent acute pancreatitis that demonstrates distinct histologic features, including diffuse, periductal, acinar, and septal inflammatory infiltrates comprised of a pure or predominant population of eosinophils, eosinophilic phlebitis and arteritis, and localized eosinophilic infiltrates with pseudocyst formation. It is associated with elevated serum immunoglobulin E levels, an elevated eosinophil count with systemic manifestations, and eosinophilic infiltrates in other organs of the gastrointestinal tract. We present a case of eosinophilic pancreatitis in a 44-year-old man who was diagnosed after pancreatic resection for recurrent bouts of acute pancreatitis. While the gross and histologic evaluations matched other reported cases of eosinophilic pancreatitis, our patient had only minimal peripheral eosinophilia, no reported history of symptoms related to elevated eosinophilia or immunoglobulin E, and only mild eosinophilic infiltrates in his gallbladder.

    Pancreatic ductal obstruction leading to ductal dilation and recurrent pancreatitis is uncommon in children. Treatment is dependent upon etiology but consists of decompression of the pancreatic duct (PD) proximally, if possible, by endoscopic retrograde cholangiopancreatography (ERCP) intervention or surgical decompression with pancreaticojejunal anastomosis. After institutional review board approval, we retrospectively reviewed the records for 2 children who underwent lateral pancreaticojejunostomy for pancreatic ductal dilation. Data, including demographics, diagnostic studies, operative details, complications, outcomes, and follow-up, were analyzed. Case 1 was a 4-year-old female with pancreatic ductal obstruction with multiple episodes of recurrent pancreatitis and failure of ERCP to clear her PD of stones. She underwent a laparoscopic cholecystectomy with a lateral pancreaticojejunostomy (Puestow procedure). She recovered well with no further episodes of pancreatitis and normal pancreatic function 4 years later. Case 2 was a 2-year-old female who developed recurrent pancreatitis and was found to have papillary stenosis and long common bile-PD channel. Despite multiple sphincterotomies, laparoscopic cholecystectomy, and laparoscopic hepaticoduodenostomy, she continued to experience episodes of pancreatitis. She underwent a laparoscopy converted to open lateral pancreaticojejunostomy. Her recovery was also smooth having had no episodes of pancreatitis or hospital admissions for over 2 years following the Puestow. Indication for lateral pancreaticojejunostomy or Puestow procedure is rare in children and even less often performed using laparoscopy. In our small experience, both patients with pancreatic ductal obstruction managed with Puestow's procedure enjoy durable symptom and pain relief in the long term.

    X-ray diagnosis of the pancreatic gland calculous damage as well as chronic pancreatitis have been studied in 23 patients. A methodologic approach to examination of this group of patients was defined. Posteroanterior radiography has been shown to be of decisive importance in diagnosis of the calcified pancreatic gland. Duodenography and choleduodenography both considerably promote recognition of chronic pancreatitis. The radiologic method also allows one to reveal a series of complications: the common bile duct compression, duodenal stenosis, pancreatic tumor in the presence of chronic pancreatitis, malabsorption syndrome

    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 contrast-enhanced 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.

    Chronic pancreatitis is suggested to be one of the risk factors for the development of pancreatic cancer. The aim of this study was to confirm the high incidence of pancreatic cancer in patients with chronic pancreatitis in Japan and to determine the factors associated with the risk for pancreatic cancer in patients with chronic pancreatitis. The working group of the Research Committee of Intractable Disease supported by the Ministry of Health, Labour and Welfare of Japan carried out a nationwide survey to investigate the relationship between chronic pancreatitis and pancreatic cancer. This retrospective study included patients diagnosed with chronic pancreatitis who had had at least 2 years of follow-up. They were contacted through 22 Japanese referral centers experienced in the management of chronic pancreatitis. The standardized incidence ratio (95 CI) of pancreatic cancer was 11.8 (7.1-18.4). The incidence of pancreatic cancer was significantly lower in patients who had received surgery for chronic pancreatitis than in those who had not undergone surgery (hazard ratio estimated by Cox regression 0.11; 95% CI, 0.0014-0.80; P = .03). Patients who continued to drink alcohol after diagnosis of chronic pancreatitis showed a significantly higher incidence of pancreatic cancer than those who stopped drinking after diagnosis of chronic pancreatitis (hazard ratio, 5.07; 95% CI, 1.13-22.73; P = .03). This study confirmed that chronic pancreatitis is an important risk factor for the development of pancreatic cancer in Japan. Patients who underwent surgery for the treatment of chronic pancreatitis had significantly lower incidences of pancreatic cancer. Surgery for chronic pancreatitis may inhibit the development of pancreatic cancer in patients with chronic pancreatitis. Copyright © 2013 Mosby, Inc. All rights reserved.

    Pancreatic polypeptide (PP) and peptide YY (PYY) are inhibitors of pancreatic exocrine secretion in vivo but not in vitro, which suggests intermediate mechanisms of action. To examine the role of pancreatic blood flow in these inhibitory effects, xenon-133 gas clearance was used to measure pancreatic blood flow while simultaneously measuring pancreatic exocrine secretion. PP or PYY (400 pmol/kg/h) was administered during the intermediate hour of a 3-h secretin (125 ng/kg/h)/cholecystokinin octapeptide (CCK-8) (50 ng/kg/h) infusion. Exocrine secretion and pancreatic blood flow during the PP or PYY hours were compared with that observed in the first and third hours of the secretin/CCK-8 infusion. PP and PYY significantly inhibited secretin/CCK-8-induced pancreatic exocrine secretion. In addition, PYY (but not PP) significantly reduced pancreatic blood flow during secretin/CCK-8 stimulation. Nevertheless, there was no correlation between pancreatic blood flow and bicarbonate or protein outputs. It is concluded that changes in pancreatic blood flow do not mediate the inhibitory effects of PP or PYY on the exocrine pancreas

    The aim of this prospective study was to assess pancreatic exocrine function in patients recovering from a first attack of acute pancreatitis, and to evaluate its relationship to severity of attack, extent of pancreatic necrosis and severity of pancreatic endocrine insufficiency. Between December 2000 and November 2001, 23 patients were prospectively evaluated. Pancreatic exocrine function was measured by the faecal elastase-1 test and insufficiency was classified as moderately impaired or severely impaired. Pancreatic necrosis was determined by contrast-enhanced CT scan, and its extent was categorised according to Balthazar's classification. The severity of pancreatic endocrine insufficiency was categorised according to insulin dependence. Attacks were classified as mild (n = 16) or severe (n = 7) according to the Atlanta criteria. Pancreatic exocrine insufficiency was significantly more frequent in patients recovering from severe attacks than mild (n = 6, 86% vs. n = 2, 13%; p = 0.002), and in those who developed pancreatic necrosis or pseudocyst than those who did not (6 of 7 patients vs. 2 of 16 patients, and 5 of 5 patients vs. 3 of 18 patients respectively; p = 0.002). The development of exocrine insufficiency correlated strongly with the extent of pancreatic necrosis (r = -0.754, p pancreatic endocrine insufficiency (n = 4, r = -0.453, p = 0.03). Pancreatic exocrine insufficiency is a common occurrence in patients recovering from severe acute pancreatitis, and its severity correlates with the extent of pancreatic necrosis and the severity of concomitant pancreatic endocrine insufficiency.

    A correlation of several clinical parameters and pancreatitis morphological alterations observed in chronic alcoholics with and without pancreatic is presented. Three groups of patients were studied: asymptomatic chronic alcoholics (24); non-alcoholic controls (10); and cases with advanced chronic pancreatitis (6). Clinical, biochemical and functional studies were performed. Morphological studies were made on surgical biopsy specimens in light and electron microscopy. The results of this study showed: 1) fat accumulates within pancreatic acinar cells in alcoholics drinking more than 80 g of ethanol per day; 2) ultrastructural changes found in acinar cells of the alcoholics are similar to those described for liver cells; 3) the alterations found in alcoholics without pancreatitis are also observed in those with advanced chronic pancreatitis. An attempt to correlate the sequential changes in the histopathology of alcoholic pancreatic disease with the clinical picture and secretory patterns was made. According to these observations, admitting the ultrastructural similarities between the liver and the pancreas and the recently demonstrated abnormalities of lipid metabolism in pancreatic cells in experimental animal research, the authors postulate a toxic-metabolic mechanism as a likely hypothesis for the pathogenesis of chronic alcoholic inflammation of the pancreas.

    For patients with chronic pancreatitis and a dilated pancreatic duct, ductal decompression is recommended. We conducted a randomized trial to compare endoscopic and surgical drainage of the pancreatic duct. All symptomatic patients with chronic pancreatitis and a distal obstruction of the pancreatic duct but without an inflammatory mass were eligible for the study. We randomly assigned patients to undergo endoscopic transampullary drainage of the pancreatic duct or operative pancreaticojejunostomy. The primary end point was the average Izbicki pain score during 2 years of follow-up. The secondary end points were pain relief at the end of follow-up, physical and mental health, morbidity, mortality, length of hospital stay, number of procedures undergone, and changes in pancreatic function. Thirty-nine patients underwent randomization: 19 to endoscopic treatment (16 of whom underwent lithotripsy) and 20 to operative pancreaticojejunostomy. During the 24 months of follow-up, patients who underwent surgery, as compared with those who were treated endoscopically, had lower Izbicki pain scores (25 vs. 51, Psurgical drainage (P=0.007). Rates of complications, length of hospital stay, and changes in pancreatic function were similar in the two treatment groups, but patients receiving endoscopic treatment required more procedures than did patients in the surgery group (a median of eight vs. three, PSurgical drainage of the pancreatic duct was more effective than endoscopic treatment in patients with obstruction of the pancreatic duct due to chronic pancreatitis.

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

  14. TRAUMATIC PANCREATITIS

    1953-01-01

    Traumatic pancreatitis should be considered as a diagnostic possibility when trauma to the epigastrium is followed by phenomena suggestive of intra-abdominal injury. The presence or absence of hyperamylasemia should be established immediately. Even when traumatic pancreatitis is believed to exist, any suggestion of injury to other viscera should indicate laparotomy. Retroperitoneal rupture of the duodenum may simulate traumatic pancreatitis in all respects, including hyperamylasemia. X-ray studies may be of value in differentiation. Non-complicated traumatic pancreatitis is best treated conservatively. Gunshot and knife wounds of the pancreas should be drained. PMID:13094537

    Pancreatitis is inflammation of pancreas and caused by a number of factors including pancreatic duct obstruction, alcoholism, and mutation in the cationic trypsinogen gene. Pancreatitis is represented as acute pancreatitis with acute inflammatory responses and; chronic pancreatitis characterized by marked stroma formation with a high number of infiltrating granulocytes (such as neutrophils, eosinophils), monocytes, macrophages and pancreatic stellate cells (PSCs). These inflammatory cells are known to play a central role in initiating and promoting inflammation including pancreatic fibrosis, i.e., a major risk factor for pancreatic cancer. A number of inflammatory cytokines are known to involve in promoting pancreatic pathogenesis that lead pancreatic fibrosis. Pancreatic fibrosis is a dynamic phenomenon that requires an intricate network of several autocrine and paracrine signaling pathways. In this review, we have provided the details of various cytokines and molecular mechanistic pathways (i.e., Transforming growth factor-β/SMAD, mitogen-activated protein kinases, Rho kinase, Janus kinase/signal transducers and activators, and phosphatidylinositol 3 kinase) that have a critical role in the activation of PSCs to promote chronic pancreatitis and trigger the phenomenon of pancreatic fibrogenesis. In this review of literature, we discuss the involvement of several pro-inflammatory and anti-inflammatory cytokines, such as in interleukin (IL)-1, IL-1β, IL-6, IL-8 IL-10, IL-18, IL-33 and tumor necrosis factor-α, in the pathogenesis of disease. Our review also highlights the significance of several experimental animal models that have an important role in dissecting the mechanistic pathways operating in the development of chronic pancreatitis, including pancreatic fibrosis. Additionally, we provided several intermediary molecules that are involved in major signaling pathways that might provide target molecules for future therapeutic treatment strategies for

    Full Text Available Abstract Hereditary chronic pancreatitis (HCP is a very rare form of early onset chronic pancreatitis. With the exception of the young age at diagnosis and a slower progression, the clinical course, morphological features and laboratory findings of HCP do not differ from those of patients with alcoholic chronic pancreatitis. As well, diagnostic criteria and treatment of HCP resemble that of chronic pancreatitis of other causes. The clinical presentation is highly variable and includes chronic abdominal pain, impairment of endocrine and exocrine pancreatic function, nausea and vomiting, maldigestion, diabetes, pseudocysts, bile duct and duodenal obstruction, and rarely pancreatic cancer. Fortunately, most patients have a mild disease. Mutations in the PRSS1 gene, encoding cationic trypsinogen, play a causative role in chronic pancreatitis. It has been shown that the PRSS1 mutations increase autocatalytic conversion of trypsinogen to active trypsin, and thus probably cause premature, intrapancreatic trypsinogen activation disturbing the intrapancreatic balance of proteases and their inhibitors. Other genes, such as the anionic trypsinogen (PRSS2, the serine protease inhibitor, Kazal type 1 (SPINK1 and the cystic fibrosis transmembrane conductance regulator (CFTR have been found to be associated with chronic pancreatitis (idiopathic and hereditary as well. Genetic testing should only be performed in carefully selected patients by direct DNA sequencing and antenatal diagnosis should not be encouraged. Treatment focuses on enzyme and nutritional supplementation, pain management, pancreatic diabetes, and local organ complications, such as pseudocysts, bile duct or duodenal obstruction. The disease course and prognosis of patients with HCP is unpredictable. Pancreatic cancer risk is elevated. Therefore, HCP patients should strongly avoid environmental risk factors for pancreatic cancer.

    Chronic pancreatitis is defined as a pathological fibro-inflammatory syndrome of the pancreas in individuals with genetic, environmental and/or other risk factors who develop persistent pathological responses to parenchymal injury or stress. Potential causes can include toxic factors (such as alcohol or smoking), metabolic abnormalities, idiopathic mechanisms, genetics, autoimmune responses and obstructive mechanisms. The pathophysiology of chronic pancreatitis is fairly complex and includes acinar cell injury, acinar stress responses, duct dysfunction, persistent or altered inflammation, and/or neuro-immune crosstalk, but these mechanisms are not completely understood. Chronic pancreatitis is characterized by ongoing inflammation of the pancreas that results in progressive loss of the endocrine and exocrine compartment owing to atrophy and/or replacement with fibrotic tissue. Functional consequences include recurrent or constant abdominal pain, diabetes mellitus (endocrine insufficiency) and maldigestion (exocrine insufficiency). Diagnosing early-stage chronic pancreatitis is challenging as changes are subtle, ill-defined and overlap those of other disorders. Later stages are characterized by variable fibrosis and calcification of the pancreatic parenchyma; dilatation, distortion and stricturing of the pancreatic ducts; pseudocysts; intrapancreatic bile duct stricturing; narrowing of the duodenum; and superior mesenteric, portal and/or splenic vein thrombosis. Treatment options comprise medical, radiological, endoscopic and surgical interventions, but evidence-based approaches are limited. This Primer highlights the major progress that has been made in understanding the pathophysiology, presentation, prevalence and management of chronic pancreatitis and its complications.

    The objectives of the present study were to determine nutritional status, pancreatic function, and morphological changes of the pancreatic remnant after pancreatic tumor resection in children. The nutritional status was evaluated by the patterns of growth. Pancreatic function was evaluated by using a questionnaire, the Bristol stool form chart, the serum levels of fasting blood glucose, and hemoglobin A1c (HbA1c). Morphological changes of the pancreatic remnant were evaluated by computed tomography, magnetic resonance image, or magnetic resonance cholangiopancreatography. The present study consisted of 6 patients with pancreatic tumor (5 solid pseudopapillary tumors of the pancreas and 1 pancreatoblastoma) who underwent the following operations: tumor enucleation (3), distal pancreatectomy with splenectomy (1), and pylorus-preserving pancreatoduodenectomy (PPPD [2]). The serum levels of HbA1c have been gradually elevated in 2 patients with PPPD. A significant decrease in pancreatic parenchymal thickness and dilatation of the main pancreatic duct were observed in 2 patients with PPPD. Endocrine pancreatic insufficiency after PPPD may be explainable by obstructive pancreatitis after operation. Taking together the results of pancreatic endocrine function and morphological changes of pancreatic remnant after PPPD, tumor enucleation should be considered as surgical approach in children with pancreas head tumor whenever possible.

    Pancreatic cancer is an aggressive malignancy with a poor prognosis. The disease and its treatment can cause significant nutritional impairments that often adversely impact patient quality of life (QOL). The pancreas has both exocrine and endocrine functions and, in the setting of cancer, both systems may be affected. Pancreatic exocrine insufficiency (PEI) manifests as weight loss and steatorrhea, while endocrine insufficiency may result in diabetes mellitus. Surgical resection, a central component of pancreatic cancer treatment, may induce or exacerbate these dysfunctions. Nutritional and metabolic dysfunctions in patients with pancreatic cancer lack characterization, and few guidelines exist for nutritional support in patients after surgical resection. We reviewed publications from the past two decades (1995-2016) addressing the nutritional and metabolic status of patients with pancreatic cancer, grouping them into status at the time of diagnosis, status at the time of resection, and status of nutritional support throughout the diagnosis and treatment of pancreatic cancer. Here, we summarize the results of these investigations and evaluate the effectiveness of various types of nutritional support in patients after pancreatectomy for pancreatic adenocarcinoma (PDAC). We outline the following conservative perioperative strategies to optimize patient outcomes and guide the care of these patients: (1) patients with albumin 10% should postpone surgery and begin aggressive nutrition supplementation; (2) patients with albumin endocrine and exocrine pancreatic insufficiency alongside implementation of appropriate treatment to improve the patient's quality of life.

    2003-10-01

    Early diagnosis of pancreatic trauma has always been challenging because of the lack of correlation between the initial clinical symptomatology, radiologic and laboratory findings, and the severity of the injury. Thanks to the improved performance of spiral CT scanning and magnetic resonance pancreatography, it is now often possible to make an early diagnosis of pancreatic contusion, to localize the site of the injury, and (most importantly) to identify injury to the main pancreatic duct which has major implications for the management of the case. When the trauma victim is unstable, radiologic work-up may be impossible and urgent laparotomy is required. Control of hemorrhage is the primary concern here and a damage control approach with packing may be appropriate; if the pancreatic head has been destroyed, a pancreaticoduodenectomy with delayed reconstruction may be required. If the trauma victim is stable, the treatment strategy will be governed by a variety of parameters--age, clinical condition, associated local anatomic findings (pancreatitis, injury to the duodenum or biliary tract), involvement of the pancreatic duct, and localization of the injury within the gland (to right or left of the mesenteric vessels).

    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)

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

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

    Full Text Available BACKGROUND: Surgery is the traditional treatment for symptomatic pancreatic pseudocysts, but the morbidity is still too high. Minimally invasive endoscopic approaches have been encouraged. AIMS: To evaluate the efficacy of endoscopic ultrasound-guided endoscopic transmural drainage of pancreatic pseudocysts. METHODS: From January, 2003 to August, 2006, 31 consecutive symptomatic patients submitted to 37 procedures at the same endoscopic unit were retrospectively analysed. Chronic and acute pancreatitis were found in, respectively, 17 (54.8% and 10 (32.3% cases. Bulging was present in 14 (37.8% cases. Cystogastrostomy or cystoduodenostomy were created with an interventional linear echoendoscope under endosonographic and fluoroscopic control. By protocol, only a single plastic stent, without nasocystic drain, was used. Straight or double pigtail stents were used in, respectively, 22 (59.5% and 15 (40.5% procedures. RESULTS: Endoscopic ultrasound-guided transmural drainage was successful in 29 (93.5% patients. Two cases needed surgery, both due to procedure-related complications. There was no mortality related to the procedure. Twenty-four patients were followed-up longer than 4 weeks. During a mean follow-up of 12.6 months, there were six (25% symptomatic recurrences due to stent clogging or migration, with two secondary infections. Median time for developing complications and recurrence of the collections was 3 weeks. These cases were successfully managed with new stents. Complications were more frequent in patients treated with straight stents and in those with a recent episode of acute pancreatitis. CONCLUSIONS: Endoscopic transmural drainage provides an effective approach to the management of pancreatic pseudocysts.RACIONAL: A abordagem cirúrgica é o tratamento tradicional para os pseudocistos sintomáticos de pâncreas, contudo a morbidade permanece elevada.

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

    Full Text Available 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 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.

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

    We had developed the Unifying-Autoimmune-Pancreatitis-Criteria (U-AIP) to diagnose autoimmune pancreatitis (AiP) within the M-ANNHEIM classification of chronic pancreatitis. In 2011, International-Consensus-Diagnostic-Criteria (ICDC) to diagnose AiP have been published. We had applied the U-AIP long before the ICDC were available. The aims of the study were, first, to describe patients with AiP diagnosed by the U-AIP; second, to compare diagnostic accuracies of the U-AIP and other diagnostic systems; third, to evaluate the clinical applicability of the U-AIP. From 1998 until 2008, we identified patients with AiP using U-AIP, Japanese-, Korean-, Asian-, Mayo-HISORt-, Revised-Mayo-HISORt- and Italian-criteria. We retrospectively verified the diagnosis by ICDC and Revised-Japanese-2011-criteria, compared diagnostic accuracies of all systems and evaluated all criteria in consecutive patients with pancreatitis (2009 until 2010, Pancreas-Outpatient-Clinic-Cohort, n = 84). We retrospectively validated our diagnostic approach in consecutive patients with a pancreatic lesion requiring surgery (Surgical-Cohort, n = 98). Overall, we identified 21 patients with AiP. Unifying-Autoimmune-Pancreatitis-Criteria and ICDC presented the highest diagnostic accuracies (each 98.8%), highest Youden indices (each 0.95238), and highest proportions of diagnosed patients (each n = 20/21, U-AIP/ICDC vs. other diagnostic systems, p Pancreatitis-Criteria revealed a satisfactory clinical applicability and offered an additional approach to diagnose AiP.

    Full Text Available Objective: To analyze the assessment value of the quantitative indexes of pancreatic CT perfusion scanning for malignant degree of pancreatic cancer. Methods: A total of 58 patients with space-occupying pancreatic lesions were divided into 20 patients with pancreatic cancer and 38 patients with benign pancreatic lesions after pancreatic CT perfusion. Patients with pancreatic cancer received palliative surgery, and the cancer tissue and para-carcinoma tissue specimens were collected during operation. The differences in pancreatic CT perfusion scanning parameter values and serum tumor marker levels were compared between patients with pancreatic cancer and patients with benign pancreatic lesions, mRNA expression levels of malignant molecules in pancreatic cancer tissue and para-carcinoma tissue were further determined, and the correlation between pancreatic CT perfusion scanning parameter values and malignant degree of pancreatic cancer was analyzed. Results: CT perfusion scanning BF, BV and Per values of patients with pancreatic cancer were lower than those of patients with benign pancreatic lesions; serum CA19-9, CEA, CA125 and CA242 levels were higher than those of patients with benign pancreatic lesions (P<0.05; mRNA expression levels of Bcl-2, Bcl-xL and survivin in pancreatic cancer tissue samples were higher than those in paracarcinoma tissue samples, and mRNA expression levels of P53 and Bax were lower than those in para-carcinoma tissue samples (P<0.05; CT perfusion scanning parameters BF, BV and Per values of patients with pancreatic cancer were negatively correlated with CA19-9, CEA, CA125 and CA242 levels in serum as well as mRNA expression levels of Bcl-2, Bcl-xL and survivin in pancreatic cancer tissue, and positively correlated with mRNA expression levels of P53 and Bax in pancreatic cancer tissue (P<0.05. Conclusions: Pancreatic CT perfusion scanning is a reliable way to judge the malignant degree of pancreatic cancer and plays a

    Highlights: ► Pancreatic stellate cells (PSCs) promote the progression of pancreatic cancer. ► Pancreatic cancer cells co-cultured with PSCs showed enhanced spheroid formation. ► Expression of stem cell-related genes ABCG2, Nestin and LIN28 was increased. ► Co-injection of PSCs enhanced tumorigenicity of pancreatic cancer cells in vivo. ► This study suggested a novel role of PSCs as a part of the cancer stem cell niche. -- Abstract: The interaction between pancreatic cancer cells and pancreatic stellate cells (PSCs), a major profibrogenic cell type in the pancreas, is receiving increasing attention. There is accumulating evidence that PSCs promote the progression of pancreatic cancer by increasing cancer cell proliferation and invasion as well as by protecting them from radiation- and gemcitabine-induced apoptosis. Recent studies have identified that a portion of cancer cells, called “cancer stem cells”, within the entire cancer tissue harbor highly tumorigenic and chemo-resistant phenotypes, which lead to the recurrence after surgery or re-growth of the tumor. The mechanisms that maintain the “stemness” of these cells remain largely unknown. We hypothesized that PSCs might enhance the cancer stem cell-like phenotypes in pancreatic cancer cells. Indirect co-culture of pancreatic cancer cells with PSCs enhanced the spheroid-forming ability of cancer cells and induced the expression of cancer stem cell-related genes ABCG2, Nestin and LIN28. In addition, co-injection of PSCs enhanced tumorigenicity of pancreatic cancer cells in vivo. These results suggested a novel role of PSCs as a part of the cancer stem cell niche.

    Full Text Available Advanced techniques have been developed to overcome difficult cannulation cases in endoscopic retrograde cholangiopancreatography (ERCP. Pancreatic duct guidewire placement method (PGW is performed in difficult cannulation cases; it is possible that it places patients at risk of post-ERCP pancreatitis (PEP. The mechanism of PEP is still unclear, but pancreatic duct pressure and injury of pancreatic duct are known causes of PEP. Therefore, we hypothesized a relationship between pancreatic duct diameter and PEP and predicted that PGW would increase the risk of PEP in patients with non-dilated pancreatic ducts. This study aimed to investigate whether PGW increased the risk of PEP in patients with pancreatic duct diameter ≤ 3 mm.We analyzed 332 patients with pancreatic duct ≤ 3 mm who performed first time ERCP session. The primary endpoint was the rate of adverse event of PEP. We evaluated the risk of PEP in patients who had undergone PGW compared to those who had not, using the inverse probability of treatment weighting (IPTW analysis.PGW was found to be an independent risk factor for PEP by univariate analysis (odds ratio [OR], 2.45; 95% confidence interval [CI], 1.12-5.38; p = 0.03 after IPTW in patients with pancreatic duct diameter ≤ 3 mm. Adjusted for all covariates, PGW remained an independent risk factor for PEP (OR, 3.12; 95% CI, 1.33-7.33; p = 0.01.Our results indicate that PGW in patients with pancreatic duct diameter ≤ 3 mm increases the risk of PEP.

    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.

    A duodenum-preserving pancreatic head resection (DPPHR) was first reported by Beger et al. in 1980. However, its application has been limited to chronic pancreatitis because of it is a subtotal pancreatic head resection. In 1990, we reported duodenum-preserving total pancreatic head resection (DPTPHR) in 26 cases. This opened the way for total pancreatic head resection, expanding the application of this approach to tumorigenic morbidities such as intraductal papillary mucinous tumor (IMPT), other benign tumors, and small pancreatic cancers. On the other hand, Nakao et al. reported pancreatic head resection with segmental duodenectomy (PHRSD) as an alternative pylorus-preserving pancreatoduodenectomy technique in 24 cases. Hirata et al. also reported this technique as a new pylorus-preserving pancreatoduodenostomy with increased vessel preservation. When performing DPTPHR, the surgeon should ensure adequate duodenal blood supply. Avoidance of duodenal ischemia is very important in this operation, and thus it is necessary to maintain blood flow in the posterior pancreatoduodenal artery and to preserve the mesoduodenal vessels. Postoperative pancreatic functional tests reveal that DPTPHR is superior to PPPD, including PHSRD, because the entire duodenum and duodenal integrity is very important for postoperative pancreatic function.

    Pancreatectomy, including pancreatoduodenectomy and distal pancreatectomy, often causes postoperative pancreatic exocrine insufficiency (PEI). Our aim was to clarify a relationship between remnant pancreatic volume and postoperative PEI. A total of 227 patients who underwent pancreatoduodenectomy or distal pancreatectomy were enrolled in this study. All patients underwent a (13)C-labeled mixed triglyceride breath test to assess pancreatic exocrine function and abdominal dynamic computed tomography for assessing remnant pancreatic volume after pancreatectomy at a median of 7 months postoperatively. The percent (13)CO2 cumulative dose at 7 hours (% dose (13)C cum 7 h) pancreatectomy were performed in 174 (76.7%) and 53 (23.3%) patients, respectively. Of the 227 patients, 128 (56.3%) developed postoperative PEI. Postoperative % dose (13)C cum 7 h was strongly correlated with remnant pancreatic volume (r = .509, P pancreatectomy (P pancreatectomy. Remnant pancreatic volume may predict postoperative PEI in patients who undergo pancreatectomy. Copyright © 2016 Elsevier Inc. All rights reserved.

    The pathogenic mechanism of pancreatitis is poorly understood. Recent evidence implicates defective autophagy in pancreatitis responses; however, the pathways mediating impaired autophagy in pancreas remain largely unknown. Here, we investigate the role of lysosome associated membrane proteins (LAMPs) in pancreatitis. We analyzed changes in LAMPs in experimental models and human pancreatitis, and the underlying mechanisms: LAMP de-glycosylation and degradation. LAMP cleavage by cathepsin B (CatB) was analyzed by mass spectrometry. We used mice deficient in LAMP-2 to assess its role in pancreatitis. Pancreatic levels of LAMP-1 and LAMP-2 greatly decrease across various pancreatitis models and in human disease. Pancreatitis does not trigger LAMPs' bulk de-glycosylation, but induces their degradation via CatB-mediated cleavage of LAMP molecule close to the boundary between luminal and transmembrane domains. LAMP-2 null mice spontaneously develop pancreatitis that begins with acinar cell vacuolization due to impaired autophagic flux, and progresses to severe pancreas damage characterized by trypsinogen activation, macrophage-driven inflammation, and acinar cell death. LAMP-2 deficiency causes a decrease in pancreatic digestive enzymes content, stimulates the basal and inhibits CCK-induced amylase secretion by acinar cells. The effects of LAMP-2 knockout and acute cerulein pancreatitis overlap, which corroborates the pathogenic role of LAMP decrease in experimental pancreatitis models. The results indicate a critical role for LAMPs, particularly LAMP-2, in maintaining pancreatic acinar cell homeostasis, and provide evidence that defective lysosomal function, resulting in impaired autophagy, leads to pancreatitis. Mice with LAMP-2 deficiency present a novel genetic model of human pancreatitis caused by lysosomal/autophagic dysfunction.

    A casual relation between pancreatic pressure and pain has been searched for decades but lack of appropriate methods for pressure measurements has hindered progress. During the 1980's the needle method has been used for direct intraoperative pancreatic tissue fluid pressure measurements and later...... for percutaneous sonographically-guided pressure measurements. Clinical and experimental evaluation of the method showed comparable results at intraoperative and percutaneous measurements and little week-to-week variation. Furthermore, comparable pressures in duct and adjacent pancreatic tissue were found, i.......e. the needle pressure mirrors the intraductal pressure. Comparisons of pain registrations, morphological and functional parameters with pancreatic tissue fluid pressure measurements have revealed a relation between pressure and pain which probably is causal. In patients with pain the high pressures previously...

    Full Text Available PURPOSE: Study hemodynamic pattern and lipoperoxidation during methylene blue (MB treatment on taurocholate - enterokinase induced acute pancreatitis (AP. METHODS: Thirty pigs were equally divided in control group; MB group; AP group; MB previous AP group; and MB after 90 min of induced AP group. MB was given iv in a bolus dose (2mg.kg-1 followed by maintenance dose (2 mg.kg-1.h-1. Hemodynamic parameters were recorded continuously during 180 min by Swan-Ganz catheter. Blood samples were taken every 60 min to determine arterial and venous nitrate, malondialdehyde (MDA and amylase. Pancreatic tissue was removed for histopathologic study. RESULTS: In AP group MBP and CO decreased over time 33% (p0.05 serum MDA when associated to AP. After induced AP, MB did not reverse MBP and CO decrease. There was no difference in serum amylase and necro-hemorrhagic findings with MB treatment. CONCLUSIONS: In this taurocholate-induced AP model MB treatment delayed hemodynamic shock and decreases serum nitrate levels but increases serum MDA levels. No volemic replacement was done and it may have been a mitigated factor to a poor tissue perfusion and impairment microcirculation. Further investigations are needed to elucidate MB treatment role during AP treatment.OBJETIVO: estudar o perfil hemodinâmico e a lipoperoxidação durante o tratamento com azul de metileno (AM de pancreatite aguda (PA induzida por taurocolato-enteroquinase.

    Pancreatic adenocarcinomas and diabetes mellitus are responsible for the deaths of around two million people each year worldwide. Patients with chronic pancreatitis do not die directly of this disease, except where the pathology is hereditary. Much current literature supports the involvement of bile salt-dependent lipase (BSDL), also known as carboxyl ester lipase (CEL), in the pathophysiology of these pancreatic diseases. The purpose of this review is to shed light on connections between chronic pancreatitis, diabetes, and pancreatic adenocarcinomas by gaining an insight into BSDL and its variants. This enzyme is normally secreted by the exocrine pancreas, and is diverted within the intestinal lumen to participate in the hydrolysis of dietary lipids. However, BSDL is also expressed by other cells and tissues, where it participates in lipid homeostasis. Variants of BSDL resulting from germline and/or somatic mutations (nucleotide insertion/deletion or nonallelic homologous recombination) are expressed in the pancreas of patients with pancreatic pathologies such as chronic pancreatitis, MODY-8, and pancreatic adenocarcinomas. We discuss the possible link between the expression of BSDL variants and these dramatic pancreatic pathologies, putting forward the suggestion that BSDL and its variants are implicated in the cell lipid metabolism/reprogramming that leads to the dyslipidemia observed in chronic pancreatitis, MODY-8, and pancreatic adenocarcinomas. We also propose potential strategies for translation to therapeutic applications.

    Full Text Available Chronic pancreatitis is a progressive inflammatory disease resulting in permanent structural damage of the pancreas. It is mainly characterized by recurring epigastric pain and pancreatic insufficiency. In addition, progression of the disease might lead to additional complications, such as pseudocyst formation or development of pancreatic cancer. The medical and surgical treatment of chronic pancreatitis has changed significantly in the past decades. With regard to surgical management, pancreatic head resection has been shown to be a mainstay in the treatment of severe chronic pancreatitis because the pancreatic head mass is known to trigger the chronic inflammatory process. Over the years, organ-preserving procedures, such as the duodenum-preserving pancreatic head resection and the pylorus-preserving Whipple, have become the surgical standard and have led to major improvements in pain relief, preservation of pancreatic function, and quality of life of patients.

    Food allergy, a commonly increasing problem worldwide, defined as an adverse immune response to food. A variety of immune-related effector cells such as mast cells, eosinophils, neutrophils, and T cells are involved in food-related allergic responses categorized as IgE mediated, non-IgE mediated, and mixed (IgE and non-IgE) depending upon underlying immunological mechanisms. The dietary antigens mainly target the gastrointestinal tract including pancreas that gets inflamed due to food allergy and leads acute pancreatitis. Reports indicate several food proteins induce pancreatitis; however, detailed underlying mechanism of food-induced pancreatitis is unexplored. The aim of the review is to understand and update the current scenario of food-induced pancreatitis. A comprehensive literature search of relevant research articles has been performed through PubMed, and articles were chosen based on their relevance to food allergen-mediated pancreatitis. Several cases in the literature indicate that acute pancreatitis has been provoked after the consumption of mustard, milk, egg, banana, fish, and kiwi fruits. Food-induced pancreatitis is an ignored and unexplored area of research. The review highlights the significance of food in the development of pancreatitis and draws the attention of physicians and scientists to consider food allergies as a possible cause for initiation of pancreatitis pathogenesis.

    There has been no definite examining technique for the early diagnosis of pancreatic diseases, especially small cancers of the pancreas less than 3 cm. Plain abdominal X-rays do not produce reliable roentgenological signs of acute pancreatitis, but the advent of CT has elucidated the condition to some extent. Upper gastrointestinal series are alleged to demonstrate abnormal findings in 80% of cases of pancreatic cancer or cyst. Pancreatic RI scintigraphy expresses the function and anatomy, and the sensitivity with 75 Se is 88%, similar to 87% by US and 80% by CT. Although endoscopic retrograde cholangiopancreatography visualizes extrapancreatic secretory function, as well as the morphology of pancreas, differentiation is not easy in many cases. The greatest indication for US was cysts. The detection rate of pancreatic cancers is similar between plain and contrast CTs, and pancreatic angiography is not specific for pancreatic cancers.

    The effect of intravenous infusion of synthetic human pancreatic polypeptide (HPP) or a rabbit anti-PP serum on pancreatic exocrine secretion was studied in 10 dogs with gastric and Thomas duodenal cannulas. The infusion of HPP, achieved a plasma PP concentration that mimicked the peak plasma concentration of PP in both interdigestive and postprandial states. This dose of HPP significantly inhibited pancreatic secretion in the interdigestive state. By contrast, immunoneutralization of circulating PP by a rabbit anti-PP serum resulted in significant increases in both interdigestive and postprandial pancreatic secretion, including water, bicarbonate, and protein. The increase in the pancreatic secretion paralleled a decrease in circulating PP level, which lasted for as long as 5 days. Furthermore, the anti-PP serum blocked the inhibitory action of exogenous HPP on pancreatic exocrine secretion. The present study indicates that endogenous PP plays a significant role in the regulation of the pancreatic exocrine secretion in both interdigestive and digestive states. Thus the authors conclude that PP is another hormone regulating pancreatic exocrine secretion in dogs

    Full Text Available Kara L Raphael, Field F Willingham Division of Digestive Diseases, Department of Medicine, Emory University School of Medicine, Atlanta, GA, USA Abstract: Hereditary pancreatitis (HP is a rare cause of acute, recurrent acute, and chronic pancreatitis. It may present similarly to other causes of acute and chronic pancreatitis, and often there has been a protracted evaluation prior to the diagnosis of HP. Since it was first described in 1952, multiple genetic defects that affect the action of digestive enzymes in the pancreas have been implicated. The most common mutations involve the PRSS1, CFTR, SPINK1, and CTRC genes. New mutations in these genes and previously unrecognized mutations in other genes are being discovered due to the increasing use of next-generation genomic sequencing. While the inheritance pathways of these genetic mutations may be variable and complex, sometimes involving coinheritance of other mutations, the clinical presentation of patients tends to be similar. Interactions with environmental triggers often play a role. Patients tend to present at an early age (prior to the second decade of life and have a significantly increased risk for the development of pancreatic adenocarcinoma. Patients with HP may develop sequelae of chronic pancreatitis such as strictures and fluid collections as well as exocrine and endocrine insufficiency. Management of patients with HP involves avoidance of environmental triggers, surveillance for pancreatic adenocarcinoma, medical therapy for endocrine and exocrine insufficiency, pain management, and endoscopic or surgical treatment for complications. Care for affected patients should be individualized, with an emphasis on early diagnosis and multidisciplinary involvement to develop a comprehensive treatment strategy.

    2016-11-01

    Full Text Available Chymotrypsin C (CTRC is a trypsinogen synthesized by pancreatic acinar cells and secreted by pancreatic duct cells and belongs to the family of serine chymotrypsin. The main function of CTRC is to regulate the balance between activation and degradation of trypsin and maintain the structural and functional integrity of the pancreas. CTRC gene mutations can cause abnormal activation of trypsinogen and abnormal degradation of trypsin and then lead to the development of pancreatitis. The downregulation or absence of CTRC expression may be associated with the development and metastasis of pancreatic cancer. This article introduces the structure and biological function of CTRC and its mechanism of action in the development and progression of pancreatitis and pancreatic cancer.

    Patients could develop endocrine and exocrine pancreatic insufficiency after acute pancreatitis (AP), but the morbidity, risk factors and outcome remain unclear. The aim of the present study was to evaluate the incidence of endocrine and exocrine pancreatic insufficiency after AP and the risk factors of endocrine pancreatic insufficiency through a long-term follow-up investigation. Follow-up assessment of the endocrine and exocrine function was conducted for the discharged patients with AP episodes. Oral Glucose Tolerance Test (OGTT) and faecal elastase-1(FE-1) test were used as primary parameters. Fasting blood-glucose (FBG), fasting insulin (FINS), glycosylated hemoglobin HBA1c, 2-h postprandial blood glucose (2hPG), Homa beta cell function index (HOMA-β), homeostasis model assessment of insulin resistance (HOMA-IR) and FE-1 were collected. Abdominal contrast-enhanced computed tomography (CECT) was performed to investigate the pancreatic morphology and the other related data during hospitalization was also collected. One hundred thirteen patients were included in this study and 34 of whom (30.1%) developed diabetes mellitus (DM), 33 (29.2%) suffered impaired glucose tolerance (IGT). Moreover, 33 patients (29.2%) developed mild to moderate exocrine pancreatic insufficiency with 100μg/gpancreatic insufficiency with FE-1pancreatic necrosis was significant higher than that in the non-pancreatic necrosis group (X 2  = 13.442,P = 0.001).

    Full Text Available A asma aguda grave é uma emergência médica que deve ser diagnosticada e tratada rapidamente. O tratamento inicial inclui broncodilatadores e corticosteróides sistêmicos. Em casos graves, com fraca resposta ao tratamento padrão, o sulfato de magnésio venoso surge como opção terapêutica. O objetivo deste artigo foi revisar a literatura sobre o uso do sulfato de magnésio venoso na asma aguda em crianças no pronto-socorro no que se refere a eficácia, indicação, dosagem, efeitos adversos e contraindicações. Realizada revisão narrativa por meio das Bases de dados Medline, Lilacs e Cochrane Database of Systmatic Reviews, entre 2000 e 2010. Utilizados os descritores: asthma, children, emergency, magnesium sulfate. Incluídos oito ensaios clínicos controlados, três meta-análises, um estudo retrospectivo, oito artigos de revisão e um estudo transversal. A eficácia do magnésio venoso em crianças foi observada por vários autores, com raros efeitos adversos. Seu uso foi indicado para os pacientes com asma aguda moderada e grave que não responderam ao tratamento inicial com broncodilatador e corticosteróide. As contraindicações em pediatria são poucas. Entre elas estão insuficiência renal e bloqueio atrioventricular. Existem poucos relatos da interação do magnésio com drogas de uso pediátrico. Apesar da segurança, na prática, o magnésio venoso é pouco usado na asma aguda em pediatria. Na maioria das vezes, é indicado tardiamente para impedir falência respiratória e internação na unidade de cuidados intensivos. Os estudos demonstram que o magnésio venoso é uma droga eficaz e segura na criança com asma aguda grave, porém o seu uso no pronto-socorro ainda é limitado.

    Full text: Introduction: Computed Tomography (CT) is the imaging modality of choice for the diagnosis and staging of acute pancreatitis and its complications. Objectives and tasks: The purpose of this presentation is to demonstrate the findings in CT images which are useful for staging acute pancreatitis according to Balthazar, their significance and restrictions. Materials and methods: CT images from patients who were referred to our Department for an abdominal CT scan for the diagnosis or/and staging of acute pancreatitis were retrospectively studied. Results: In acute pancreatitis, CT helps to stage the severity of inflammatory process, to detect pancreatic necrosis and to depict local complications. CT severity index (CTSI), which was proposed by Balthazar et al, combines the grade of pancreatitis with the extent of pancreatic necrosis assigning points to the patients in order to find the severity index which scales from 0-10. More points are given for a higher grade of pancreatitis and for more extensive necrosis. Types of pancreatitis according to CTSI are: interstitial (Balthazar grade A-C), exudative (Balthazar grade D or E), necrotising (Balthazar grade E, CTSI:10) and central gland necrotising. Patients with pancreatitis but no collections or necrosis have an interstitial (mild) pancreatitis. In exudative pancreatitis there is normal enhancement of the entire pancreas associated with extensive peripancreatic collections. Necrotizing (severe) pancreatitis is characterized by protacted clinical course, high incidence of local complications and high mortality rate. Central gland necrosis is a subtype of necrotizing pancreatitis. Conclusions: The combination of CT imaging and clinical and laboratory evaluation allows the early diagnosis of acute pancreatitis. Acute pancreatitis may vary from a mild uneventful disease to a severe life-threatening illness with multisystemic organ failure. Thus, it is crucial to identify patients who are at high risk of severe

    Pancreatic surgery is challenging and associated with high morbidity, mainly represented by postoperative pancreatic fistula (POPF) and its further consequences. Identification of risk factors for POPF is essential for proper postoperative management. Evaluation of the role of morphological and histological features of pancreatic stump, other than main pancreatic duct diameter and glandular texture, in POPF occurrence after pancreaticoduodenectomy. Between March 2011 and April 2013, we performed 145 consecutive pancreaticoduodenectomies. We intraoperatively recorded morphological features of pancreatic stump and collected data about postoperative morbidity. Our dedicated pathologist designed a score to quantify fibrosis and inflammation of pancreatic tissue. Overall morbidity was 59,3%. Mortality was 4,1%. POPF rate was 28,3%, while clinically significant POPF were 15,8%. Male sex (P = 0.009), BMI ≥ 25 (P = 0.002), prolonged surgery (P = 0.001), soft pancreatic texture (P < 0.001), small pancreatic duct (P < 0.001), pancreatic duct decentralization on stump anteroposterior axis, especially if close to the posterior margin (P = 0.031), large stump area (P = 0.001), and extended stump mobilization (P = 0.001) were related to higher POPF rate. Our fibrosis-and-inflammation score is strongly associated with POPF (P = 0.001). Pancreatic stump features evaluation, including histology, can help the surgeon in fitting postoperative management to patient individual risk after pancreaticoduodenectomy.

    l-asparaginase has been an element in the treatment for acute lymphoblastic leukaemia (ALL) and non-Hodgkin lymphoma since the late 1960s and remains an essential component of their combination chemotherapy. Among the major toxicities associated with l-asparaginase therapy are pancreatitis, allergic reactions, thrombotic events, hepatotoxicity and hyperlipidaemia. Acute pancreatitis is one of the most common reasons for stopping treatment with l-asparaginase. Short-term complications of asparaginase-associated pancreatitis include development of pseudocysts and pancreatic necrosis. Long-term complications include chronic pancreatitis and diabetes. The pathophysiology of asparaginase-associated pancreatitis remains to be uncovered. Individual clinical and genetic risk factors have been identified, but they are only weak predictors of pancreatitis. This review explores the definition, possible risk factors, treatment and complications of asparaginase-associated pancreatitis. © 2012 Blackwell Publishing Ltd.

    Full Text Available Pancreatic cancer is an aggressive malignancy with a poor prognosis. The disease and its treatment can cause significant nutritional impairments that often adversely impact patient quality of life (QOL. The pancreas has both exocrine and endocrine functions and, in the setting of cancer, both systems may be affected. Pancreatic exocrine insufficiency (PEI manifests as weight loss and steatorrhea, while endocrine insufficiency may result in diabetes mellitus. Surgical resection, a central component of pancreatic cancer treatment, may induce or exacerbate these dysfunctions. Nutritional and metabolic dysfunctions in patients with pancreatic cancer lack characterization, and few guidelines exist for nutritional support in patients after surgical resection. We reviewed publications from the past two decades (1995–2016 addressing the nutritional and metabolic status of patients with pancreatic cancer, grouping them into status at the time of diagnosis, status at the time of resection, and status of nutritional support throughout the diagnosis and treatment of pancreatic cancer. Here, we summarize the results of these investigations and evaluate the effectiveness of various types of nutritional support in patients after pancreatectomy for pancreatic adenocarcinoma (PDAC. We outline the following conservative perioperative strategies to optimize patient outcomes and guide the care of these patients: (1 patients with albumin < 2.5 mg/dL or weight loss > 10% should postpone surgery and begin aggressive nutrition supplementation; (2 patients with albumin < 3 mg/dL or weight loss between 5% and 10% should have nutrition supplementation prior to surgery; (3 enteral nutrition (EN should be preferred as a nutritional intervention over total parenteral nutrition (TPN postoperatively; and, (4 a multidisciplinary approach should be used to allow for early detection of symptoms of endocrine and exocrine pancreatic insufficiency alongside implementation of

    Chronic pancreatitis is a progressive inflammatory disease giving rise to several complications that need to be treated accordingly. Because pancreatic surgery has significant morbidity and mortality, less invasive therapy seems to be an attractive option. This paper reviews current state-of-the-art strategies to treat chronic pancreatitis without surgery and the current guidelines for the medical therapy of chronic pancreatitis. Endoscopic therapy of complications of chronic pancreatitis such as pain, main pancreatic duct strictures and stones as well as pseudocysts is technically feasible and safe. The long-term outcome, however, is inferior to definitive surgical procedures such as resection or drainage. On the other hand, the medical therapy of pancreatic endocrine and exocrine insufficiency is well established and evidence based. Endoscopic therapy may be an option to bridge for surgery and in children/young adolescents and those unfit for surgery. Pain in chronic pancreatitis as well as treatment of pancreatic exocrine insufficiency follows established guidelines. Copyright © 2013 S. Karger AG, Basel.

    We report a 50-year-old male with pseudocysts in the pancreatic tail associated with chronic pancreatitis successfully treated by transpapillary cyst drainage. He had previously undergone ultrasonography-guided percutaneous cyst drainage for a pancreatic pseudocyst in our hospital. He was readmitted due to abdominal pain and fever. Computed tomography showed recurrence of a pseudocyst in the pancreatic tail measuring 5 cm in diameter. Since conservative treatment failed, endoscopic retrograde pancreatography was performed. There was communication between the pseudocyst and the main pancreatic duct, and pancreatic duct stenosis proximal to the pseudocyst. First, transpapillary pancreatic duct drainage was performed using a plastic stent, but the pseudocyst did not decrease in size and became infected. After removal of the stent, a pigtail type nasocystic catheter was placed in the pseudocyst via the pancreatic duct. The pseudocyst infection immediately disappeared, and the pseudocyst gradually decreased and disappeared. After removal of the nasocystic catheter, no recurrence was observed. As transpapillary drainage of pancreatic pseudocyst, cyst drainage and pancreatic duct drainage have been reported. In our patient with pseudocyst in the pancreatic tail, duct drainage was ineffective and the pseudocyst was infected, whereas cyst drainage was very effective. We considered that cyst drainage by a nasocystic catheter was the first-line therapy as the transpapillary drainage of the pancreatic pseudocyst.

    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

    Although robot-assisted pancreatic surgery has been considered critically in the past, it is nowadays an established standard technique in some centers, for distal pancreatectomy and pancreatic head resection. Compared with the laparoscopic approach, the use of robot-assisted surgery seems to be advantageous for acquiring the skills for pancreatic, bile duct and vascular anastomoses during pancreatic head resection and total pancreatectomy. On the other hand, the use of the robot is associated with increased costs and only highly effective and professional robotic programs in centers for pancreatic surgery will achieve top surgical and oncological quality, acceptable operation times and a reduction in duration of hospital stay. Moreover, new technologies, such as intraoperative fluorescence guidance and augmented reality will define additional indications for robot-assisted pancreatic surgery.

    Full Text Available Groove Pancreatitis (GP is a rare form of focal chronic pancreatitis involving the pancreatico-duodenal groove (PDG. GP was first described by Becker in 1973. Though, GP has been described so many years ago, it is still unfamiliar among most physicians because of lack of sufficient case studies and clinical similarity of GP to conventional pancreatitis. Imaging based differentiation of GP from other lesions, like pancreatic and periampullary adenocarcinoma is also not possible in all the cases, unless there are typical findings favoring GP. Since, the line of treatment and outcome is totally different in these two conditions, appreciation of the fine differences between these two entities is very significant. Groove pancreatitis is symptomatically treated with medicines and only for patients with continuous and severe symptoms which are not amenable to medical treatment surgical management is considered. Radiological differentiation of GP from pancreatic and periampullary malignancies will help to avoid unnecessary surgery in the initial stages. We report two cases of GP, one of pure and other of segmental form where we found typical imaging features which pointed to the diagnosis of GP with a small discussion about the Computed tomography (CT and Magnetic Resonance Imaging (MRI appearance of this entity as well as its differential diagnosis.

    Pancreatic duct stone (PDS) is a common complication of chronic pancreatitis. Surgery is a common therapeutic option for PDS. In this study we assessed the surgical procedures for PDS in patients with chronic pancreatitis at our hospital. Between January 2004 and September 2009, medical records from 35 patients diagnosed with PDS associated with chronic pancreatitis were retrospectively reviewed and the patients were followed up for up to 67 months. The 35 patients underwent ultrasonography, computed tomography, or both, with an overall accuracy rate of 85.7%. Of these patients, 31 underwent the modified Puestow procedure, 2 underwent the Whipple procedure, 1 underwent simple stone removal by duct incision, and 1 underwent pancreatic abscess drainage. Of the 35 patients, 28 were followed up for 4-67 months. There was no postoperative death before discharge or during follow-up. After the modified Puestow procedure, abdominal pain was reduced in patients with complete or incomplete stone clearance (P>0.05). Steatorrhea and diabetes mellitus developed in several patients during a long-term follow-up. Surgery, especially the modified Puestow procedure, is effective and safe for patients with PDS associated with chronic pancreatitis. Decompression of intraductal pressure rather than complete clearance of all stones predicts postoperative outcome.

    Full Text Available Introducción: la obstrucción biliar es motivo frecuente de morbilidad en los pacientes con metástasis hepáticas, adenopatías periportales y cáncer hepatobiliopancreático. La colangitis aguda es la complicación más temida, debido a su mortalidad. En este trabajo se presentan los primeros abordajes percutáneos realizados por cirujanos del Hospital Clínicoquirúrgico "Hermanos Ameijeiras" como herramienta para el tratamiento urgente de esta entidad. Objetivo: caracterizar el drenaje percutáneo transparietohepático de urgencia en pacientes con colangitis aguda e ictericia obstructiva. Métodos: se realizó un estudio descriptivo, prospectivo y aplicado con 30 pacientes atendidos de esta forma en dicha institución entre enero de 2008 y diciembre de 2010. Resultados: el diagnóstico etiológico preponderante fue el de tumor maligno de la cabeza del páncreas. La localización baja de la lesión duplicó a la localización alta. La mejoría clínica de la ictericia se evidenció en la mayoría de los pacientes después de una semana tras el procedimiento: el drenaje percutáneo constituyó el método definitivo en el 73,3 % de los pacientes. Las edades medias para los distintos diagnósticos etiológicos exhibieron diferencias estadísticamente significativas. No hubo complicaciones ni mortalidad relacionadas con el procedimiento. Conclusiones: el drenaje biliar percutáneo guiado por ultrasonido es una herramienta útil y segura para el tratamiento de urgencia de la colangitis aguda. Es un método que pueden realizar los cirujanos generales con entrenamiento adecuado y específico, y tiene asociadas pocas complicaciones.

    Four members of the PAX family, PAX2, PAX4, PAX6 and PAX8 are known to be expressed in the pancreas. Accumulated evidences indicate that several pancreatic expressed PAX genes play a significant role in pancreatic development/functionality and alterations in these genes are involved in the pathogenesis of pancreatic diseases. Areas covered: In this review, we summarize the ongoing research related to pancreatic PAX genes in diabetes mellitus and pancreatic neuroendocrine tumors. We dissect the current knowledge at different levels; from mechanistic studies in cell lines performed to understand the molecular processes controlled by pancreatic PAX genes, to in vivo studies using rodent models that over-express or lack specific PAX genes. Finally, we describe human studies associating variants on pancreatic-expressed PAX genes with pancreatic diseases. Expert opinion: Based on the current literature, we propose that future interventions to treat pancreatic neuroendocrine tumors and diabetes mellitus could be developed via the modulation of PAX4 and/or PAX6 regulated pathways.

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

    Benign and malignant pathologies of the pancreas can result in a relevant chronic disease burden. This is aggravated by morbidities resulting from surgical resections as well as from progression of the underlying condition. The aim was to summarize the current evidence regarding epidemiology, pathophysiology, diagnosis and treatment of endocrine and exocrine pancreatic insufficiency, as well as of pancreatic pseudocysts. A selective literature search was performed and a summary of the currently available data on the surgical sequelae after pancreatic resection is given. Reduction of healthy pancreatic parenchyma down to 10-15 % leads to exocrine insufficiency with malabsorption and gastrointestinal complaints. Orally substituted pancreatic enzymes are the therapy of choice. Loss of pancreatic islets and/or islet function leads to endocrine insufficiency and pancreoprivic diabetes mellitus. Inflammatory, traumatic and iatrogenic injuries of the pancreas can lead to pancreatic pseudocysts, which require endoscopic, interventional or surgical drainage if symptomatic. Finally, pancreatic surgery harbors the long-term risk of gastrointestinal anastomotic ulcers, bile duct stenosis, portal vein thrombosis and chronic pain syndrome. As the evidence is limited, an interdisciplinary and individually tailored approach for delayed pancreatic morbidity is recommended.

    Autoimmune pancreatitis is a rare disease which can even mimic pancreatic tumor, however, unlike the latter, it requires not surgical but conservative management. Correct diagnosis and differential diagnosis of autoimmune pancreatitis and treatment of these patients requires up-to-date and evidence based management guidelines. The Hungarian Pancreatic Study Group proposed to prepare an evidence based guideline based on the available international guidelines and evidences. The preparatory and consultation task force appointed by the Hungarian Pancreatic Study Group translated and complemented and/or modified the international guidelines if it was necessary. 29 relevant clinical questions in 4 topics were defined (Basics; Diagnosis; Differential diagnostics; Therapy). Evidence was classified according to the UpToDate(®) grading system. The draft of the guidelines was presented and discussed at the consensus meeting on September 12, 2014. All clinial questions were accepted with almost total (more than 95%) agreement. The present guideline is the first evidence based autoimmune pancreatitis guideline in Hungary. The guideline may provide very important and helpful data for tuition of autoimmune pancreatitis, for everyday practice and for establishing proper finance. Therefore, the authors believe that these guidelines will widely become a basic reference in Hungary.

    Purpose: To clarify whether there are differences in MRI findings between pancreatic lymphomas and autoimmune pancreatitis (AIP). Materials and methods: MRI of 8 patients with pancreatic lymphomas and 21 patients with AIP were retrospectively reviewed. For multifocal pancreatic lymphomas (n = 2) and AIP (n = 4), the largest 2 lesions were evaluated. Ten pancreatic lymphomas and 25 AIP were compared on three bases: the signal intensity on T2-weighted images, internal homogeneity, and presence or absence of capsule-like rim. In 8 lymphomas and 19 AIP, the enhancement pattern on dynamic MRI was compared, as well. Results: On T2-weighted images, pancreatic lymphomas comprised 5, 5 and 4 lesions with low (iso), slightly high, and moderately high intensity, respectively, while the numbers for AIP were 14, 10, and 1 (P < 0.01). Nine of 10 (90%) lymphomas appeared homogenous, and 11 of 25 (44%) AIP were homogenous (P < 0.05). A capsule-like rim was present in 9 of 25 (36%) AIP, but was not seen in lymphomas (P < 0.05). On dynamic MRI, 18 of 19 (94.7%) AIP showed persistent (n = 5) or delayed enhancement (n = 13), and 6 of 8 (75%) lymphomas showed low intensity without delayed enhancement (P < 0.001). Conclusion: MRI findings for pancreatic lymphomas and AIP were significantly different, which may be helpful for the differential diagnosis of these two diseases.

    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 Introduction. Pancreatic surgery is challenging and associated with high morbidity, mainly represented by postoperative pancreatic fistula (POPF and its further consequences. Identification of risk factors for POPF is essential for proper postoperative management. Aim of the Study. Evaluation of the role of morphological and histological features of pancreatic stump, other than main pancreatic duct diameter and glandular texture, in POPF occurrence after pancreaticoduodenectomy. Patients and Methods. Between March 2011 and April 2013, we performed 145 consecutive pancreaticoduodenectomies. We intraoperatively recorded morphological features of pancreatic stump and collected data about postoperative morbidity. Our dedicated pathologist designed a score to quantify fibrosis and inflammation of pancreatic tissue. Results. Overall morbidity was 59,3%. Mortality was 4,1%. POPF rate was 28,3%, while clinically significant POPF were 15,8%. Male sex (P=0.009, BMI≥25 (P=0.002, prolonged surgery (P=0.001, soft pancreatic texture (P<0.001, small pancreatic duct (P<0.001, pancreatic duct decentralization on stump anteroposterior axis, especially if close to the posterior margin (P=0.031, large stump area (P=0.001, and extended stump mobilization (P=0.001 were related to higher POPF rate. Our fibrosis-and-inflammation score is strongly associated with POPF (P=0.001. Discussion and Conclusions. Pancreatic stump features evaluation, including histology, can help the surgeon in fitting postoperative management to patient individual risk after pancreaticoduodenectomy.

    Pediatric acute pancreatitis has been on the rise in the last decades, with an incidence close to adult pancreatitis. In the majority of cases acute pancreatitis resolves spontaneously, but in a subset of children the disease progresses to severe acute pancreatitis with attendant morbidity and mortality. Pediatric acute pancreatitis in this era is recognized as a separate entity from adult acute pancreatitis given that the causes and disease outcomes are different. There are slow but important advances made in understanding the best management for acute pancreatitis in children from medical, interventional, and surgical aspects. Supportive care with fluids, pain medications, and nutrition remain the mainstay for acute pancreatitis management. For complicated or severe pancreatitis, specialized interventions may be required with endoscopic or drainage procedures. Surgery has an important but limited role in pediatric acute pancreatitis.

    Chronic pancreatitis (CP) is characterized by abnormal pancreatic morphology and impaired endocrine and exocrine function. However, little is known about the relationship between pancreatic morphology and function, and also the association with the etiology and clinical manifestations of CP. The aim was to explore pancreatic morphology and function with advanced MRI in patients with CP and healthy controls (HC) METHODS: Eighty-two patients with CP and 22 HC were enrolled in the study. Morphological imaging parameters included pancreatic main duct diameter, gland volume, fat signal fraction and apparent diffusion coefficient (ADC) values. Functional secretin-stimulated MRI (s-MRI) parameters included pancreatic secretion (bowel fluid volume) and changes in pancreatic ADC value before and after secretin stimulation. Patients were classified according to the modified Cambridge and M-ANNHEIM classification system and fecal elastase was collected. All imaging parameters differentiated CP patients from HC; however, correlations between morphological and functional parameters in CP were weak. Patients with alcoholic and non-alcoholic etiology had comparable s-MRI findings. Fecal elastase was positively correlated to pancreatic gland volume (r = 0.68, P = 0.0016) and negatively correlated to Cambridge classification (r = -0.35, P pancreatic gland volume was significantly decreased in the severe stages of CP (P = 0.001). S-MRI provides detailed information about pancreatic morphology and function and represents a promising non-invasive imaging method to characterize pancreatic pathophysiology and may enable monitoring of disease progression in patients with CP.

    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 75 Se-selenomethionine using a Toshiba gamma camera. The relationship between the degree of pancreatic uptake of 75 Se-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 75 Se-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.)

    Patients with predicted severe necrotizing pancreatitis as diagnosed by C-reactive protein (>150 mg/L) and/or contrast-enhanced computed tomography should be managed in the intensive care unit. Prophylactic broad-spectrum antibiotics reduce infection rates and survival in severe necrotizing pancreatitis. Endoscopic retrograde cholangiopancreatography and endoscopic sphincterotomy is a causative therapy for gallstone pancreatitis with impacted stones, biliary sepsis, or obstructive jaundice. Fine needle aspiration for bacteriology should be performed to differentiate between sterile and infected pancreatic necrosis in patients with sepsis syndrome. Infected pancreatic necrosis in patients with clinical signs and symptoms of sepsis is an indication for surgery. Patients with sterile pancreatic necrosis should be managed conservatively. Surgery in patients with sterile necrosis may be indicated in cases of persistent necrotizing pancreatitis and in the rare cases of "fulminant acute pancreatitis." Early surgery, within 14 days after onset of the disease, is not recommended in patients with necrotizing pancreatitis. The surgical approach should be organ-preserving (debridement/necrosectomy) and combined with a postoperative management concept that maximizes postoperative evacuation of retroperitoneal debris and exudate. Minimally invasive surgical procedures have to be regarded as an experimental approach and should be restricted to controlled trials. Cholecystectomy should be performed to avoid recurrence of gallstone-associated acute pancreatitis.

    Pancreatic exocrine insufficiency (PEI) occurs when the amounts of enzymes secreted into the duodenum in response to a meal are insufficient to maintain normal digestive processes. The main clinical consequence of PEI is fat maldigestion and malabsorption, resulting in steatorrhoea. Pancreatic exocrine function is commonly assessed by conducting a 3-day faecal fat test and by measuring levels of faecal elastase-1 and serum trypsinogen. Pancreatic enzyme replacement therapy is the mainstay of treatment for PEI. In adults, the initial recommended dose of pancreatic enzymes is 25,000 units of lipase per meal, titrating up to a maximum of 80,000 units of lipase per meal. In infants and children, the initial recommended dose of pancreatic enzymes is 500 units of lipase per gram of dietary fat; the maximum daily dose should not exceed 10,000 units of lipase per kilogram of bodyweight. Oral pancreatic enzymes should be taken with meals to ensure adequate mixing with the chyme. Adjunct therapy with acid-suppressing agents may be useful in patients who continue to experience symptoms of PEI despite high-dose enzyme therapy. A dietitian experienced in treating PEI should be involved in patient management. Dietary fat restriction is not recommended for patients with PEI. Patients with PEI should be encouraged to consume small, frequent meals and to abstain from alcohol. Medium-chain triglycerides do not provide any clear nutritional advantage over long-chain triglycerides, but can be trialled in patients who fail to gain or to maintain adequate bodyweight in order to increase energy intake.

  8. PKD signaling and pancreatitis

    2016-01-01

    Background Acute pancreatitis is a serious medical disorder with no current therapies directed to the molecular pathogenesis of the disorder. Inflammation, inappropriate intracellular activation of digestive enzymes, and parenchymal acinar cell death by necrosis are the critical pathophysiologic processes of acute pancreatitis. Thus, it is necessary to elucidate the key molecular signals that mediate these pathobiologic processes and develop new therapeutic strategies to attenuate the appropriate signaling pathways in order to improve outcomes for this disease. A novel serine/threonine protein kinase D (PKD) family has emerged as key participants in signal transduction, and this family is increasingly being implicated in the regulation of multiple cellular functions and diseases. Methods This review summarizes recent findings of our group and others regarding the signaling pathway and the biological roles of the PKD family in pancreatic acinar cells. In particular, we highlight our studies of the functions of PKD in several key pathobiologic processes associated with acute pancreatitis in experimental models. Results Our findings reveal that PKD signaling is required for NF-κB activation/inflammation, intracellular zymogen activation, and acinar cell necrosis in rodent experimental pancreatitis. Novel small-molecule PKD inhibitors attenuate the severity of pancreatitis in both in vitro and in vivo experimental models. Further, this review emphasizes our latest advances in the therapeutic application of PKD inhibitors to experimental pancreatitis after the initiation of pancreatitis. Conclusions These novel findings suggest that PKD signaling is a necessary modulator in key initiating pathobiologic processes of pancreatitis, and that it constitutes a novel therapeutic target for treatments of this disorder.

  9. β-Cell regeneration through the transdifferentiation of pancreatic cells: Pancreatic progenitor cells in the pancreas.

    2016-05-01

    Pancreatic progenitor cell research has been in the spotlight, as these cells have the potential to replace pancreatic β-cells for the treatment of type 1 and 2 diabetic patients with the absence or reduction of pancreatic β-cells. During the past few decades, the successful treatment of diabetes through transplantation of the whole pancreas or isolated islets has nearly been achieved. However, novel sources of pancreatic islets or insulin-producing cells are required to provide sufficient amounts of donor tissues. To overcome this limitation, the use of pancreatic progenitor cells is gaining more attention. In particular, pancreatic exocrine cells, such as duct epithelial cells and acinar cells, are attractive candidates for β-cell regeneration because of their differentiation potential and pancreatic lineage characteristics. It has been assumed that β-cell neogenesis from pancreatic progenitor cells could occur in pancreatic ducts in the postnatal stage. Several studies have shown that insulin-producing cells can arise in the duct tissue of the adult pancreas. Acinar cells also might have the potential to differentiate into insulin-producing cells. The present review summarizes recent progress in research on the transdifferentiation of pancreatic exocrine cells into insulin-producing cells, especially duct and acinar cells.

    CT was found to be a reliable, often specific, and noninvasive method for detecting pancreatic diseases. In a study of pancreatic lesions, 37 cases having satisfactory operative and histological proofs were analyzed by CT at PMC from Jan. 1986 to Oct. 1987. The results were as following: 1. Male:female is 26:11. 2. The incidence of pancreatic disease were as follows: 1) Pancreatic cancer:21 cases (56%) a.Head:12 cases b.Body:4 cases c.Tail:1 case d.Body and tail:1 case e.Uncinate process:2 cases f.Entire pancreas: 1 case 2) Acute pancreatitis: 6 cases (16%) 3) Chronic pancreatitis:5 cases (14%) 3. The characteristic CT findings: 1) 100% of pancreatic head cancer showed focal mass or alteration of pancreatic head contour and biliary tree dilatation, and 33% (7/12) fat line obliteration. 2) All of other pancreatic cancer except head appeared as focal mass or contour alteration and fat line obliteration. 3) Total 6 cases of acute pancreatitis showed that 5 cases diffuse enlargement of pancreas, 3 fluid collection (2 cases:left anterior pararenal and posterior pararenal space and lesser sac, 1 case:only pancreas body) and 1 case abscess formation. 4) Total 5 cases of chronic pancreatitis revealed diffuse enlargement 2 cases and atrophy 1 case, pancreatic ductal dilatation 3 cases, calcification 2 cases, and biliary tree dilatation with CBD tapering appearance 1 case. 5) All cases of pseudocysts were well marginated cystic lesions that located at head in 3 cases and tail 3 cases, and 4 cases were well defined pure cystic masses but 1 case was well capsulated cyst with multiple internal septation

    The role of obesity in relation to various disease processes is being increasingly studied, with reports over the last several years increasingly mentioning its association with worse outcomes in acute disease. Obesity has also gained recognition as a risk factor for severe acute pancreatitis (SAP).The mortality in SAP may be as high as 30% and is usually attributable to multi system organ failure (MSOF) earlier in the disease, and complications of necrotizing pancreatitis later [9-11]. To date there is no specific treatment for acute pancreatitis (AP) and the management is largely expectant and supportive. Obesity in general has also been associated with poor outcomes in sepsis and other pathological states including trauma and burns. With the role of unsaturated fatty acids (UFA) as propagators in SAP having recently come to light and with the recognition of acute lipotoxicity, there is now an opportunity to explore different strategies to reduce the mortality and morbidity in SAP and potentially other disease states associated with such a pathophysiology. In this review we will discuss the role of fat and implications of the consequent acute lipotoxicity on the outcomes of acute pancreatitis in lean and obese states and during acute on chronic pancreatitis.

    The histopathology of advanced chronic alcoholic pancreatitis is dominated by cellular degeneration, atrophy and fibrosis. Sequential changes in the histopathology of alcoholic pancreatic disease has been defined and traced from initial injury to end-stage disease. These sequential histopathologies have been correlated with clinical syndrome and secretory patterns. The data are more consistent with a toxic-metabolic pathogenesis of alcoholic pancreatitis than the previous Big Duct and Small Duct hypotheses.

    Full Text Available A 45-year-old female presented with abdominal pain for 3 days without trauma history. The pain was located over the epigastric area with radiation to the back. A pancreatic pseudocyst was impressed initially according to clinical symptoms, laboratory data, and image studies. However, rapid progression of the lesions was noted later after discharge. Following image studies showed circumscribed tumors in the head, body, and tail regions of the pancreas. Surgery with the Whipple operation was performed during the second admission. The post operation course was uneventful. Pathologic results showed sarcoma of the pancreas. Primary pancreatic sarcomas are extremely rare lesions accounting for < 0.1% of all pancreatic malignancies. Pancreatic sarcomas tend to be aggressive and have a poor prognosis. In addition, < 5% of pancreatic tumors are cystic. The rarest cystic neoplasm is also the primary pancreatic sarcoma, with only a few cases having been documented. However, it should be considered in the differential diagnosis of pancreatic cystic lesions.

    Since ancient times the increase of size and hardness sometimes presented by the abdominal structure known as the pancreas has attracted attention. Portal was the first to describe the clinical signs of chronic pancreatitis in 1803. In 1815, Fleischman speculated about the potential role of excessive alcohol consumption. Comfort coined the term "chronic relapsing pancreatitis" in 1946 and described hereditary pancreatitis 6 years later. Zuidema defined tropical pancreatitis in 1959 and 2 years later Sarles described another form of pancreatitis to which Yoshida gave the name autoimmune pancreatitis in 1995. Groove pancreatitis was described by Potet in 1970. Obstructive pancreatitis was defined in 1984 and Ammann identified idiopathic pancreatitis 3 years later. This article gives a historical account of the pioneers who developed the knowledge of how to assess the characteristics that allowed the different forms of chronic pancreatitis to be defined.

    Exocrine insufficiency frequently develops in patients with pancreatic cancer owing to tumour ingrowth and pancreatic duct obstruction. Surgery might restore this function by removing the primary disease and restoring duct patency, but it may also have the opposite effect, as a result of resection of functional parenchyma and anatomical changes. This study evaluated the course of pancreatic function, before and after pancreatic resection. This prospective cohort study included patients with tumours in the pancreatic region requiring pancreatic resection in a tertiary referral centre between March 2010 and August 2012. Starting before surgery, exocrine function was determined monthly by measuring faecal elastase 1 levels (normal value over 0.200 µg per g faeces). Endocrine function, steatorrhoea-related symptoms and bodyweight were also evaluated before and after surgery. Subjects were followed from diagnosis until 6 months after surgery, or until death. Twenty-nine patients were included, 12 with pancreatic cancer, 14 with ampullary carcinoma and three with bile duct carcinoma (median tumour size 2.6 cm). Twenty-six patients underwent pancreaticoduodenectomy and three distal pancreatectomy. Thirteen patients had exocrine insufficiency at preoperative diagnosis. After a median follow-up of 6 months, this had increased to 24 patients. Diabetes was present in seven patients at diagnosis, and developed in one additional patient within 1 month after surgery. Most patients with tumours in the pancreatic region requiring pancreatic resection either had exocrine insufficiency at diagnosis or became exocrine-insufficient soon after surgical resection. © 2013 BJS Society Ltd.

    Full Text Available Pancreatic ductal adenocarcinoma (PDA accounts for 95% of all pancreatic cancers. About 230,000 PDA cases are diagnosed worldwide each year. PDA has the lowest five-year survival rate as compared to others cancers. PDA in Poland is the fifth leading cause of death after lung, stomach, colon and breast cancer. In our paper we have analysed the newest epidemiological research, some of it controversial, to establish the best practical solution for pancreatic cancer prevention in the healthy population as well as treatment for patients already diagnosed with pancreatic cancer. We found that PDA occurs quite frequently but is usually diagnosed too late, at its advanced stage. Screening for PDA is not very well defined except in subgroups of high-risk individuals with genetic disorders or with chronic pancreatitis. We present convincing, probable, and suggestive risk factors associated with pancreatic cancer, many of which are modifiable and should be introduced and implemented in our society.

In general, the treatment for pancreatitis is a supportive therapy. However, there are several reasons to escalate to surgery or another intervention. This review discusses the pathophysiology as well as medical and interventional management of necrotizing pancreatitis. Current evidence suggests that patients are best served by delaying interventions for at least 4 weeks, draining as a first resort, and debriding recalcitrant tissue using minimally invasive techniques to promote or enhance postoperative recovery while reducing wound-related complications.

    Full Text Available Background. Autoimmune pancreatitis (AIP often mimics pancreatic cancer. The diagnosis of both conditions is difficult preoperatively let alone when they coexist. Several reports have been published describing pancreatic cancer in the setting of AIP. Case Report. The case of a 53-year-old man who presented with abdominal pain, jaundice, and radiological features of autoimmune pancreatitis, with a “sausage-shaped” pancreas and bulky pancreatic head with portal vein impingement, is presented. He had a normal serum IgG4 and only mildly elevated Ca-19.9. Initial endoscopic ultrasound-(EUS- guided fine-needle aspiration (FNA of the pancreas revealed an inflammatory sclerosing process only. A repeat EUS guided biopsy following biliary decompression demonstrated both malignancy and features of autoimmune pancreatitis. At laparotomy, a uniformly hard, bulky pancreas was found with no sonographically definable mass. A total pancreatectomy with portal vein resection and reconstruction was performed. Histology revealed adenosquamous carcinoma of the pancreatic head and autoimmune pancreatitis and squamous metaplasia in the remaining pancreas. Conclusion. This case highlights the diagnostic and management difficulties in a patient with pancreatic cancer in the setting of serum IgG4-negative, Type 2 AIP.

    To evaluate the correlation between the pancreatic exocrine insufficiency estimated by cine-dynamic MRCP using spatially selective IR pulse and the severity stages (modified Cambridge classification) based on morphological changes of the pancreatic duct in patients with suspected chronic pancreatitis. Thirty-nine patients with suspected chronic pancreatitis underwent cine-dynamic MRCP with a spatially selective IR pulse. The secretion grading score (5-point scale) based on the moving distance of pancreatic juice inflow on cine-dynamic MRCP was assessed, and compared with the stage of the severity of chronic pancreatitis based on morphological changes of pancreatic duct. The stage of the severity of chronic pancreatitis based on morphological changes had significant negative correlations with the secretion grade (r=-0.698, P0.70 in 2 (33%) of 6 patients showing normal pancreatic exocrine function. It should be noted that the degree of morphological changes of pancreatic duct does not necessarily reflect the severity of pancreatic exocrine insufficiency at cine-dynamic MRCP in stage 2-3 chronic pancreatitis.

    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.

    Among late postoperative complications of pancreatectomy are the exocrine and endocrine pancreatic insufficiencies. The presence of exocrine pancreatic insufficiency imposes, as standard treatment, pancreatic enzyme replacement. Patients with chronic pancreatitis, with intractable pain or any complications with surgical treatment, are likely to present exocrine pancreatic insufficiency or have this condition worsened requiring adequate dose of pancreatic enzymes. The aim of this study is to compare the required dose of pancreatic enzyme and the enzyme replacement cost in post pancreatectomy patients with and without chronic pancreatitis. Observational cross-sectional study. In the first half of 2015 patients treated at the clinic of the Department of Gastrointestinal Surgery at Hospital das Clínicas, Universidade de São Paulo, Brazil, who underwent pancreatectomy for at least 6 months and in use of enzyme replacement therapy were included in this series. The study was approved by the Research Ethics Committee. The patients were divided into two groups according to the presence or absence of chronic pancreatitis prior to pancreatic surgery. For this study, Ptreatment was R$ 2150.5 ± 729.39; R$ 2118.18 ± 731.02 in patients without pancreatitis and R$ 2217.74 ± 736.30 in patients with pancreatitis. There was no statistically significant difference in the cost of treatment of enzyme replacement post pancreatectomy in patients with or without chronic pancreatitis prior to surgical indication.

    Full Text Available Pancreatic cancer’s high mortality rate equates closely with its incidence, thereby showing the need for development of biomarkers of its increased risk and a better understanding of its genetics, so that high-risk patients can be better targeted for screening and early potential lifesaving diagnosis. Its phenotypic and genotypic heterogeneity is extensive and requires careful scrutiny of its pattern of cancer associations, such as malignant melanoma associated with pancreatic cancer, in the familial atypical multiple mole melanoma syndrome, due to the CDKN2A germline mutation.

    Diabetes mellitus is a group of diseases defined by persistent hyperglycaemia. Type 2 diabetes, the most prevalent form, is characterised initially by impaired insulin sensitivity and subsequently by an inadequate compensatory insulin response. Diabetes can also develop as a direct consequence of other diseases, including diseases of the exocrine pancreas. Historically, diabetes due to diseases of the exocrine pancreas was described as pancreatogenic or pancreatogenous diabetes mellitus, but recent literature refers to it as type 3c diabetes. It is important to note that type 3c diabetes is not a single entity; it occurs because of a variety of exocrine pancreatic diseases with varying mechanisms of hyperglycaemia. The most commonly identified causes of type 3c diabetes are chronic pancreatitis, pancreatic ductal adenocarcinoma, haemochromatosis, cystic fibrosis, and previous pancreatic surgery. In this Review, we discuss the epidemiology, pathogenesis, and clinical relevance of type 3c diabetes secondary to chronic pancreatitis and pancreatic ductal adenocarcinoma, and highlight several important knowledge gaps.

    Pancreatic cancer is one of the most lethal malignancies. Significant progresses have been made in understanding of pancreatic cancer pathogenesis, including appreciation of precursor lesions or premalignant pancreatic intraepithelial neoplasia (PanINs), description of sequential transformation from normal pancreatic tissue to invasive pancreatic cancer and identification of major genetic and epigenetic events and the biological impact of those events on malignant behavior. However, the currently used therapeutic strategies targeting tumor epithelial cells, which are potent in cell culture and animal models, have not been successful in the clinic. Presumably, therapeutic resistance of pancreatic cancer is at least in part due to its drastic desmoplasis, which is a defining hallmark for and circumstantially contributes to pancreatic cancer development and progression. Improved understanding of the dynamic interaction between cancer cells and the stroma is important to better understanding pancreatic cancer biology and to designing effective intervention strategies. This review focuses on the origination, evolution and disruption of stromal molecular and cellular components in pancreatic cancer, and their biological effects on pancreatic cancer pathogenesis.

    Acute pancreatitis is an inflammatory condition caused by intracellular activation and extravasation of inappropriate proteolytic enzymes determining destruction of pancreatic parenchyma and peripancreatic tissues. This is a fairly common clinical condition with two main presentations, namely, endematous pancreatitis - a less severe presentation - and necrotizing pancreatitis - the most severe presentation that affects a significant part of patients. The radiological evaluation, particularly by computed tomography, plays a fundamental role in the definition of the management of severe cases, especially regarding the characterization of local complications with implications in the prognosis and in the definition of the therapeutic approach. New concepts include the subdivision of necrotizing pancreatitis into the following presentations: pancreatic parenchymal necrosis with concomitant peripancreatic tissue necrosis, and necrosis restricted to peripancreatic tissues. Moreover, there was a systematization of the terms acute peripancreatic fluid collection, pseudocyst, post-necrotic pancreatic/peripancreatic fluid collections and walled-off pancreatic necrosis. The knowledge about such terms is extremely relevant to standardize the terminology utilized by specialists involved in the diagnosis and treatment of these patients. (author)

    One hundred and two cases of acute and chronic pancreatitis were studied by computed tomography. Fluid collection was detected by CT in 45 cases, and the common extrapancreatic sites of involvement included the lesser sac (13 cases), anterior pararenal space (9 cases), transverse mesocolon (7 cases) and posterior pararenal space (5 cases). Ten cases of spontaneous resolution of pancreatic pseudocysts were encountered. Cystojejunostomy was done on 6 patients. A 4-to-6-weeks time interval has been currently accepted as necessary for pseudocyst wall maturation. However, the surgery was not possible in two patients in this series since the cyst wall was too thin. It is considered that the time over 3 months is required for surgical anastomosis of the cyst to the gastrointestinal tract. Pancreatic abscess has become the most common cause of death from pancreatitis. In this series pancreatic abscess occurred in 8 patients. Gas collection in the pancreas was observed in only one patient. In the other patients, pseudocysts had become infected and converted to abscesses. The CT number of 4 infected pseudocysts was less than 15 HU. Thus, it was not possible to distinguish infected from noninfected pseudocysts by CT. The author studied 9 patients with focal inflammatory mass of the pancreas with histologically proved severe fibrosis. All masses were small. Angiography showed occlusion or marked stenosis of the splenic vein in 3 cases. The postcontract CT (after intravenous bolus injection) in 7 cases of focal inflammatory mass demonstrated almost equal enhanced effect of the mass as compared with the adjacent normal pancreatic parenchyma. This finding is considered to be useful in distinguishing inflammatory mass from pancreatic carcinoma. (author)

  20. COMPARING THE ENZYME REPLACEMENT THERAPY COST IN POST PANCREATECTOMY PATIENTS DUE TO PANCREATIC TUMOR AND CHRONIC PANCREATITIS

    Directory of Open Access Journals (Sweden)

    Anna Victoria FRAGOSO

    Full Text Available ABSTRACT Background - Among late postoperative complications of pancreatectomy are the exocrine and endocrine pancreatic insufficiencies. The presence of exocrine pancreatic insufficiency imposes, as standard treatment, pancreatic enzyme replacement. Patients with chronic pancreatitis, with intractable pain or any complications with surgical treatment, are likely to present exocrine pancreatic insufficiency or have this condition worsened requiring adequate dose of pancreatic enzymes. Objective - The aim of this study is to compare the required dose of pancreatic enzyme and the enzyme replacement cost in post pancreatectomy patients with and without chronic pancreatitis. Methods - Observational cross-sectional study. In the first half of 2015 patients treated at the clinic of the Department of Gastrointestinal Surgery at Hospital das Clínicas, Universidade de São Paulo, Brazil, who underwent pancreatectomy for at least 6 months and in use of enzyme replacement therapy were included in this series. The study was approved by the Research Ethics Committee. The patients were divided into two groups according to the presence or absence of chronic pancreatitis prior to pancreatic surgery. For this study, P<0.05 was considered statistically significant. Results - The annual cost of the treatment was R$ 2150.5 ± 729.39; R$ 2118.18 ± 731.02 in patients without pancreatitis and R$ 2217.74 ± 736.30 in patients with pancreatitis. Conclusion - There was no statistically significant difference in the cost of treatment of enzyme replacement post pancreatectomy in patients with or without chronic pancreatitis prior to surgical indication.

    Hypercalcaemia due to primary hyperparathyroidism is a rare cause of acute pancreatitis, with a reported prevalence of 1.5 to 8%. There is no clear pathophysiological basis, but elevated parathyroid hormone and high serum calcium levels could be responsible for calcium deposit in the pancreatic ducts and activation of pancreatic enzymes, which may be the main risk factor for developing acute pancreatitis. The aim of this report is to describe four cases. Four cases are reported of severe pancreatitis associated with hypercalcaemia secondary to primary hyperparathyroidism; three of them with complications (two pseudocysts and one pancreatic necrosis). Cervical ultrasound, computed tomography, and scintigraphy using 99mTc-Sestambi, studies showed the parathyroid adenoma. Surgical resection was the definitive treatment in all four cases. None of the patients had recurrent acute pancreatitis events during follow-up. Acute pancreatitis secondary to hypercalcaemia of primary hyperparathyroidism is rare; however, when it occurs it is associated with severe pancreatitis. It is suspected in patients with elevated serum calcium and high parathyroid hormone levels. Imaging techniques such as cervical ultrasound, computed tomography, and scintigraphy using 99mTc-Sestambi, should be performed, to confirm clinical suspicion. Surgical resection is the definitive treatment with excellent results. Copyright © 2015 Academia Mexicana de Cirugía A.C. Published by Masson Doyma México S.A. All rights reserved.

    Background: Because survival after pancreaticoduodenectomy for cancer is limited, it is difficult to assess longterm pancreaticojejunal anastomotic patency. However, in patients with benign disease, pancreaticojejunal anastomotic stenosis may become problematic. What happens when pancreaticojejunal anastomosis revision is undertaken? Methods: Patients undergoing pancreatic anastomotic revision after pancreatic head resection for benign disease between 1997 and 2007 at the Medical University of South Carolina were identified. A retrospective chart review and analysis were undertaken with the approval of the Institutional Review Board for the Evaluation of Human Subjects. Longterm follow-up was obtained by patient survey at a clinic visit or by telephone. Results: During the study period, 237 patients underwent pancreatic head resection. Of these, 27 patients (17 women; median age 42 years) underwent revision of pancreaticojejunal anastomosis. Six patients (22%) had a pancreatic leak or abscess at the time of the index pancreatic head resection. The indication for revision of anastomosis was intractable pain. All patients underwent preoperative magnetic resonance cholangiopancreatography (MRCP), which indicated anastomotic stricture in 18 patients (63%). Nine other patients underwent exploration based on clinical suspicion caused by recurrent pancreatitis and stenosis was confirmed at the time of surgery. Six patients (22%) had perioperative complications after revision. The median length of stay was 12 days. There were no perioperative deaths; however, late mortality occurred in four patients (15%). Six of 23 survivors (26%) at the time of follow-up (median 56 months) reported longterm pain relief. Conclusions: Stricture of the pancreaticojejunal anastomosis after pancreatic head resection presents with recurrent pancreatitis and pancreatic pain. MRCP has good specificity in the diagnosis of anastomotic obstruction, but lacks sensitivity. Pancreaticojejunal revision

    Pancreatic cancer is one of the most deadly solid tumors, with an overall 5-year survival rate of less than 5%. Due to a non-specific clinical presentation, it is often diagnosed at an advanced stage and is rarely amenable for curative treatment. Therefore early diagnosis and appropriate staging are still essential to define the best care and to improve patient survival. Several imaging modalities are currently available for the evaluation of pancreatic cancer. This review focuses on different techniques and discusses the diagnostic management of patients with pancreatic cancer.

    Pancreatic stellate cells (PSCs) interact with pancreatic cancer cells in the tumor microenvironment. Cell constituents including microRNAs may be exported from cells within membranous nanovesicles termed exosomes. Exosomes might play a pivotal role in intercellular communication. This study aimed to clarify the microRNA signature of PSC-derived exosomes and their effects on pancreatic cancer cells. Exosomes were prepared from the conditioned medium of immortalized human PSCs. MicroRNAs were prepared from the exosomes and their source PSCs, and the microRNA expression profiles were compared by microarray. The effects of PSC-derived exosomes on proliferation, migration, and the mRNA expression profiles were examined in pancreatic cancer cells. Pancreatic stellate cell-derived exosomes contained a variety of microRNAs including miR-21-5p. Several microRNAs such as miR-451a were enriched in exosomes compared to their source PSCs. Pancreatic stellate cell-derived exosomes stimulated the proliferation, migration and expression of mRNAs for chemokine (C - X - C motif) ligands 1 and 2 in pancreatic cancer cells. The stimulation of proliferation, migration, and chemokine gene expression by the conditioned medium of PSCs was suppressed by GW4869, an exosome inhibitor. We clarified the microRNA expression profile in PSC-derived exosomes. Pancreatic stellate cell-derived exosomes might play a role in the interactions between PSCs and pancreatic cancer cells.

    The objective of this study was to investigate the value of low-dose whole pancreatic computed tomography (CT) perfusion integrated with individualized dual-energy CT (DECT) scanning in the diagnosis of pancreatic adenocarcinoma. Twenty patients with pancreatic adenocarcinoma underwent pancreatic CT perfusion as well as individualized dual-phase DECT pancreatic scans. Perfusion characteristics of non-tumourous pancreatic parenchyma and pancreatic adenocarcinoma were analysed. Weighted-average 120 kVp images and the optimal monoenergetic images in dual phase were reconstructed and the contrast noise ratio (CNR) of pancreas-to-tumour were compared. There were significant difference on blood flow as well as blood volume between pancreatic adenocarcinoma and the non-tumourous pancreatic parenchyma (P < 0.05), whereas no difference on permeability (P > 0.05). CNRs of pancreas-to-tumour in individualized pancreatic phase were significantly higher than those in venous phase (P < 0.05), and CNRs of optimal monoenergetic images were higher than those on weighted-average 120 kVp images (P < 0.05) in both phase. Total effective radiation dose of CT examination was around 9.32–13.75 mSv. Low-dose whole pancreatic CT perfusion can provide functional information, and the individualized pancreatic phase DECT scan is the optimal method for detecting pancreatic adenocarcinomas. The integration of the two techniques has great value in clinical application.

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

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

    Advances over the past decade have indicated that a complex interplay between environmental factors, genetic predisposition, alcohol abuse, and smoking lead towards the development of chronic pancreatitis. Chronic pancreatitis is a complex disorder that causes significant and chronic incapacity in patients and a substantial burden on the society. Major advances have been made in the etiology and pathogenesis of this disease and the role of genetic predisposition is increasingly coming to the fore. Advances in noninvasive diagnostic modalities now allow for better diagnosis of chronic pancreatitis at an early stage of the disease. The impact of these advances on surgical treatment is beginning to emerge, for example, patients with certain genetic predispositions may be better treated with total pancreatectomy versus lesser procedures. Considerable controversy remains with respect to the surgical management of chronic pancreatitis. Modern understanding of the neurobiology of pain in chronic pancreatitis suggests that a window of opportunity exists for effective treatment of the intractable pain after which central sensitization can lead to an irreversible pain syndrome in patients with chronic pancreatitis. Effective surgical procedures exist for chronic pancreatitis; however, the timing of surgery is unclear. For optimal treatment of patients with chronic pancreatitis, close collaboration between a multidisciplinary team including gastroenterologists, surgeons, and pain management physicians is needed.

  19. Redox signaling in acute pancreatitis

    2015-01-01

    Acute pancreatitis is an inflammatory process of the pancreatic gland that eventually may lead to a severe systemic inflammatory response. A key event in pancreatic damage is the intracellular activation of NF-κB and zymogens, involving also calcium, cathepsins, pH disorders, autophagy, and cell death, particularly necrosis. This review focuses on the new role of redox signaling in acute pancreatitis. Oxidative stress and redox status are involved in the onset of acute pancreatitis and also in the development of the systemic inflammatory response, being glutathione depletion, xanthine oxidase activation, and thiol oxidation in proteins critical features of the disease in the pancreas. On the other hand, the release of extracellular hemoglobin into the circulation from the ascitic fluid in severe necrotizing pancreatitis enhances lipid peroxidation in plasma and the inflammatory infiltrate into the lung and up-regulates the HIF–VEGF pathway, contributing to the systemic inflammatory response. Therefore, redox signaling and oxidative stress contribute to the local and systemic inflammatory response during acute pancreatitis. PMID:25778551

    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 regulatory T-cells are assumed

    Autoimmune pancreatitis (AIP) is a newly developed concept for a peculiar type of pancreatitis, and at present is recognized as a pancreatic lesion reflecting IgG4-related systemic disease. It is of utmost importance to differentiate AIP from pancreatic cancer to avoid unnecessary surgery. The current management strategies for AIP, including its clinical features, diagnostic criteria, clinical subtypes, steroid therapy and prognosis are discussed, based on our 66 AIP cases and papers searched in PubMed from 1992 to March 2011, using the term 'autoimmune pancreatitis'. A new clinicopathological entity, an 'IgG4-related sclerosing disease' is also mentioned. AIP should be considered in the differential diagnosis in elderly male patients presented with obstructive jaundice and pancreatic mass. Steroids are a standard therapy for AIP, but their regimen including maintenance therapy should be evaluated in prospective trials.

    Pancreatic trauma (PT) is associated with high morbidity and mortality; the therapeutic options remain debated. Retrospective study of PT treated in the University Hospital of Grenoble over a 22-year span. The decision for initial laparotomy depended on hemodynamic status as well as on associated lesions. Main pancreatic duct lesions were always searched for. PT lesions were graded according to the AAST classification. Of a total of 46 PT, 34 were grades II or I. Hemodynamic instability led to immediate laparotomy in 18 patients, for whom treatment was always drainage of the pancreatic bed; morbidity was 30%. Eight patients had grade III injuries, six of whom underwent immediate operation: three underwent splenopancreatectomy without any major complications while the other three who had simple drainage required re-operation for peritonitis, with one death related to pancreatic complications. Four patients had grades IV or V PT: two pancreatoduodenectomies were performed, with no major complication, while one patient underwent duodenal reconstruction with pancreatic drainage, complicated by pancreatic and duodenal fistula requiring a hospital stay of two months. The post-trauma course was complicated for all patients with main pancreatic duct involvement. Our outcomes were similar to those found in the literature. In patients with distal PT and main pancreatic duct involvement, simple drainage is associated with high morbidity and mortality. For proximal PT, the therapeutic options of drainage versus pancreatoduodenectomy must be weighed; pancreatoduodenectomy may be unavoidable when the duodenum is injured as well. Two-stage (resection first, reconstruction later) could be an effective alternative in the emergency setting when there are other associated traumatic lesions. Copyright © 2016.

    Pancreatic trauma is associated with high morbidity and mortality. Diagnosis is often difficult and surgery poses a formidable challenge. Data from 17 patients of pancreatic trauma gathered from a prospectively maintained database were analysed and the following parameters were considered: mode of injury, diagnostic modalities, associated injury, grade of pancreatic trauma and management. Pancreatic trauma was graded from I through IV, as per Modified Lucas Classification. The median age was 39 years (range 19-61). The aetiology of pancreatic trauma was blunt abdominal trauma in 14 patients and penetrating injury in 3. Associated bowel injury was present in 4 cases (3 penetrating injury and 1 blunt trauma) and 1 case had associated vascular injury. 5 patients had grade I, 3 had grade II, 7 had grade III and 2 had grade IV pancreatic trauma. Contrast enhanced computed tomography scan was used to diagnose pancreatic trauma in all patients with blunt abdominal injury. Immediate diagnosis could be reached in only 4 (28.5%) patients. 7 patients responded to conservative treatment. Of the 10 patients who underwent surgery, 6 required it for the pancreas and the duodenum. (distal pancreatectomy with splenectomy-3, pylorus preserving pancreatoduodenectomy-1, debridement with external drainage-1, associated injuries-duodenum-1). Pancreatic fistula, recurrent pancreatitis and pseudocyst formation were seen in 3 (17.05%), 2 (11.7%) and 1 (5.4%) patient respectively. Death occurred in 4 cases (23.5%), 2 each in grades III and IV pancreatic trauma. Contrast enhanced computed tomography scan is a useful modality for diagnosing, grading and following up patients with pancreatic trauma. Although a majority of cases with pancreatic trauma respond to conservative treatment, patients with penetrating trauma, and associated bowel injury and higher grade pancreatic trauma require surgical intervention and are also associated with higher morbidity and mortality.

    Pancreatitis is becoming increasingly prevalent in children, posing new challenges to pediatric health care providers. Although some general adult treatment paradigms are applicable in the pediatric population, diagnostic workup and surgical management of acute and chronic pancreatitis have to be tailored to anatomic and pathophysiological entities peculiar to children. Nonbiliary causes of acute pancreatitis in children are generally managed nonoperatively with hydration, close biochemical and clinical observation, and early initiation of enteral feeds. Surgical intervention including cholecystectomy or endoscopic retrograde cholangiopancreatography is often required in acute biliary pancreatitis, whereas infected pancreatic necrosis remains a rare absolute indication for pancreatic debridement and drainage via open, laparoscopic, or interventional radiologic procedure. Chronic pancreatitis is characterized by painful irreversible changes of the parenchyma and ducts, which may result in or be caused by inadequate ductal drainage. A variety of surgical procedures providing drainage, denervation, resection, or a combination thereof are well established to relieve pain and preserve pancreatic function. Copyright © 2012.

    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.

    Autoimmune pancreatitis (AIP) has the potential to progress to a chronic state that forms pancreatic stones. The aim of this study was to clarify the risk factors underlying pancreatic stone formation in AIP. Sixty-nine patients with AIP who had been followed for at least 3 years were enrolled for evaluation of clinical and laboratory factors as well as computed tomography and endoscopic retrograde cholangiopancreatography findings. During the course of this study, increased or de novo stone formation was seen in 28 patients, who were defined as the stone-forming group. No stones were observed in 32 patients, who were defined as the non-stone-forming group. Nine patients who had stones at diagnosis but showed no change during the course of this study were excluded from our cohort. Univariate analysis revealed no significant differences in clinical or laboratory factors associated with AIP-specific inflammation between the two groups. However, pancreatic head swelling (P = 0.006) and narrowing of both Wirsung's and Santorini's ducts in the pancreatic head region (P = 0.010) were significantly more frequent in the stone-forming group. Furthermore, multivariate analysis identified Wirsung and Santorini duct narrowing at diagnosis as a significant independent risk factor for pancreatic stone formation (OR 4.4, P = 0.019). A primary risk factor for pancreatic stone formation in AIP was narrowing of both Wirsung's and Santorini's ducts, which most presumably led to pancreatic juice stasis and stone development.

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

    Acute pancreatitis is a fascinating disease. In the United States, the two most common etiologies of acute pancreatitis are gallstones and excessive alcohol consumption. The diagnosis of acute pancreatitis is made with a combination of history, physical examination, computed tomography scan, and laboratory evaluation. Differentiating patients who will have a benign course of their pancreatitis from patients who will have severe pancreatitis is challenging to the clinician. C-reactive protein, pro-calcitonin, and the Bedside Index for Severity of Acute Pancreatitis appeared to be the best tools for the early and accurate diagnosis of severe pancreatitis. Early laparoscopic cholecystectomy is indicated for patients with mild gallstone pancreatitis. For patients who are going to have a prolonged hospitalization, enteral nutrition is preferred. Total parenteral nutrition should be reserved for patients who cannot tolerate enteral nutrition. Prophylactic antibiotics are not indicated for patients with pancreatic necrosis. Surgical intervention for infected pancreatic necrosis should be delayed as long as possible to improve patient outcomes.

    This study systematically explores the prevalence of pancreatic exocrine insufficiency (PEI) after acute pancreatitis in different subgroups of etiology (biliary/alcoholic/other), disease severity and follow-up time ( 36 months after index admission). PubMed and EMBASE databases were searched, 32 studies were included in this study level meta-analysis. In a total of 1495 patients with acute pancreatitis, tested at a mean of 36 months after index admission, the pooled prevalence of PEI was 27.1% (95%-confidence interval [CI]: 20.3%-35.1%). Patients from seven studies (n = 194) underwent direct tests with pooled prevalence of 41.7% [18.5%-69.2%]. Patients from 26 studies (n = 1305) underwent indirect tests with pooled prevalence of 24.4% [18.3%-31.8%]. In subgroup analyses on patients that underwent fecal elastase-1 tests, PEI occurred more often in alcoholic pancreatitis (22.7% [16.6%-30.1%]) than in biliary pancreatitis (10.2% [6.2%-16.4%]) or other etiology (13.4% [7.7%-22.4%]; P = 0.02). Pooled prevalence of PEI after mild and severe pancreatitis was 19.4% [8.6%-38.2%] and 33.4% [22.6%-46.3%] respectively in studies using fecal elaste-1 tests (P = 0.049). Similar results were seen in patients without (18.9% [9.3%-34.6%]) and with necrotizing pancreatitis (32.0% [18.2%-49.8%]; P = 0.053). Over time, the prevalence of PEI decreased in patients who underwent the fecal elastase-1 test and increased in patients who underwent the fecal fat analysis. After acute pancreatitis, a quarter of all patients develop PEI during follow-up. Alcoholic etiology and severe and necrotizing pancreatitis are associated with higher risk of PEI. The prevalence of PEI may change as time of follow-up increases. Copyright © 2018 IAP and EPC. Published by Elsevier B.V. All rights reserved.

    The most common aetiologies of acute pancreatitis (AP) are gallstones, alcohol and idiopathic. The impact of the aetiology of AP on the extent and morphology of pancreatic and extrapancreatic necrosis (EXPN) has not been clearly established. The aim of the present study was to assess the influence of aetiology on the presence and location of pancreatic necrosis in patients with AP. We carried out a post-hoc analysis of a previously established multicentre cohort of patients with AP in whom a computed tomography was available for review. Clinical data were obtained from the medical records. All computed tomographies were revised by the same expert radiologist. The impact of aetiology on pancreatic and EXPN was calculated. In total, 159 patients with necrotizing pancreatitis were identified from a cohort of 285 patients. The most frequent aetiologies were biliary (105 patients, 37%), followed by alcohol (102 patients, 36%) and other aetiologies including idiopathic (78 patients, 27%). No relationship was found between the aetiology and the presence of pancreatic necrosis, EXPN, location of pancreatic necrosis or presence of collections. We found no association between the aetiology of AP and the presence, extent and anatomical location of pancreatic necrosis.

    Pancreatic cancer is molecularly diverse, with few effective therapies. Increased mutation burden and defective DNA repair are associated with response to immune checkpoint inhibitors in several other cancer types. We interrogated 385 pancreatic cancer genomes to define hypermutation and its causes. Mutational signatures inferring defects in DNA repair were enriched in those with the highest mutation burdens. Mismatch repair deficiency was identified in 1% of tumors harboring different mechanisms of somatic inactivation of MLH1 and MSH2. Defining mutation load in individual pancreatic cancers and the optimal assay for patient selection may inform clinical trial design for immunotherapy in pancreatic cancer.

    Full Text Available Pancreatic cancer is the fourth leading cause of cancer death with a median survival of 6 months and a dismal 5-year survival rate of 3-5%. The development and progression of pancreatic cancer are caused by the activation of oncogenes, the inactivation of tumor suppressor genes and the deregulation of many signalling pathways. Therefore, the strategies targeting these molecules as well as their downstream signalling could be promising for the prevention and treatment of pancreatic cancer. However, although targeted therapies for pancreatic cancer have yielded encouraging results in vitro and in animal models, these findings have not been translated into improved outcomes in clinical trials. This failure is due to an incomplete understanding of the biology of pancreatic cancer and to the selection of poorly efficient or imperfectly targeted agents. In this review, we will critically present the current knowledge regarding the molecular, biochemical, clinical and therapeutic aspects of pancreatic cancer.

    The concept of autoimmune pancreatitis has recently been established, and ultrasonographic findings we obtained from five cases consistent with autoimmune pancreatitis are reported here. Case 1, a 77-year-old man, was admitted complaining of loss of body weight. Serum hepatobiliary enzymes and γ-globulin levels were elevated, and antinuclear antibody was positive, Abdominal ultrasonography showed dilatation of the intrahepatic bile duct, wall thickening of the common bile duct and hypoechoic swelling of the pancreatic head and body. ERCP revealed multiple stenosis of the intra-and extra-hepatic bile ducts, and diffuse irregular narrowing of the main pancreatic duct. The patient complained of thirst, and the minor salivary gland was examined histologically. Our diagnosis was Sjögren syndrome accompanied by sclerosing cholangitis and a pancreatic lesion. Obstructive jaundice also developed, and PTCD was therefore performed. Both the pancreatic swelling and multiple stenosis of the bile duct improved after steroids were administered. Case 2, a 71-year-old man, was admitted with jaundice. Abdominal ultrasonography showed hypoechoic swelling of the pancreas. ERCP showed stenosis of the common bile duct in the pancreatic head region and diffuse irregular narrowing of the main pancreatic duct. Histological examination of the minor salivary gland suggested Sjögren syndrome. Steroids were therefore administered because the presence of both hyper-γ-globulinemia and positive antinuclear antibody suggested involvement of the autoimmune mechanism. Steroid therapy improved the jaundice as well as the findings from the cholangiograms and pancreatograms. We also encountered three similar cases, all consistent with the concept of autoimmune pancreatitis. The ultrasonographic findings of the pancreatic lesion (1) showed them as homogeneous and markedly hypoechoic areas and, (2) visualized the main pancreatic duct in the lesion, which facilitated a differential diagnosis of the

    Full Text Available Chronic pancreatitis is a chronic inflammatory disorder of the pancreas. The etiology is multi-fold, but all lead to progressive scarring and loss of pancreatic function. Early diagnosis is difficult; and the understanding of the molecular events that underlie this progressive disease is limited. In this study, we investigated differential proteins associated with mild and severe chronic pancreatitis in comparison with normal pancreas and pancreatic cancer. Paraffin-embedded formalin-fixed tissues from five well-characterized specimens each of normal pancreas (NL, mild chronic pancreatitis (MCP, severe chronic pancreatitis (SCP and pancreatic ductal adenocarcinoma (PDAC were subjected to proteomic analysis using a "label-free" comparative approach. Our results show that the numbers of differential proteins increase substantially with the disease severity, from mild to severe chronic pancreatitis, while the number of dysregulated proteins is highest in pancreatic adenocarcinoma. Important functional groups and biological processes associated with chronic pancreatitis and cancer include acinar cell secretory proteins, pancreatic fibrosis/stellate cell activation, glycoproteins, and inflammatory proteins. Three differential proteins were selected for verification by immunohistochemistry, including collagen 14A1, lumican and versican. Further canonical pathway analysis revealed that acute phase response signal, prothrombin activation pathway, and pancreatic fibrosis/pancreatic stellate cell activation pathway were the most significant pathways involved in chronic pancreatitis, while pathways relating to metabolism were the most significant pathways in pancreatic adenocarcinoma. Our study reveals a group of differentially expressed proteins and the related pathways that may shed light on the pathogenesis of chronic pancreatitis and the common molecular events associated with chronic pancreatitis and pancreatic adenocarcinoma.

    Acute pancreatitis is an acute inflammatory process of the pancreas with variable involvement of other regional tissues or remote organ systems. Acute fluid collections and pseudocyst formation are the most frequent complications of acute pancreatitis. The aims of this study were to evaluate the incidence, risk factors, and clinical course of pancreatic fluid collections and pseudocyst formation following acute pancreatitis. A prospective multicenter study was conducted in five participating centers with 302 patients diagnosed with acute pancreatitis from January 2011 to July 2012. The incidence of pancreatic fluid collections and pseudocyst was 42.7 and 6.3 %, respectively. Patients with fluid collections were significantly younger, compared to those without fluid collections (51.5 ± 15.9 vs. 60.4 ± 16.5 years, P = 0.000). The proportion of alcoholic etiology (54.3 %) in patients with fluid collections was significantly higher compared to other etiologies (P = 0.000). C-reactive protein (CRP) (48 h) was significantly higher in patients with fluid collections, compared to patients without fluid collections (39.2 ± 77.4 vs. 15.1 ± 36.2 mg/dL, P = 0.016). LDH (48 h) was significantly higher in patients with pseudocyst formation, compared to patients with complete resolution (1,317.6 ± 706.4 vs. 478.7 ± 190.5 IU/L, P = 0.000). Pancreatic fluid collections showed spontaneous resolution in 69.8 % (90/129) and 84.2 % of the pseudocysts disappeared or decreased in size during follow up. Age, CRP (48 h), and alcohol etiology are risk factors for pancreatic fluid collections. LDH (48 h) appears to be a risk factor for pseudocyst formation. Most pseudocysts showed a decrease in size or spontaneous resolution with conservative management.

    Pancreatic cancer is a devastating disease with poor prognosis. There is very limited information available regarding the epidemiology and treatment strategies of pancreatic cancer in Central Europe. The purpose of the study was to prospectively collect and analyze data of pancreatic cancer in the Hungarian population. The Hungarian Pancreatic Study Group (HPSG) organized prospective, uniform data collection. Altogether 354 patients were enrolled from 14 Hungarian centers. Chronic pancreatitis was present in 3.7% of the cases, while 33.7% of the patients had diabetes. Family history for pancreatic cancer was positive in 4.8%. The most frequent presenting symptoms included pain (63.8%), weight loss (63%) and jaundice (52.5%). The reported frequency of smoking and alcohol consumption was lower than expected (28.5% and 27.4%, respectively). The majority of patients (75.6%) were diagnosed with advanced disease. Most patients (83.6%) had a primary tumor located in the pancreatic head. The histological diagnosis was ductal adenocarcinoma in 90.7% of the cases, while neuroendocrine tumor was present in 5.3%. Biliary stent implantation was performed in 166 patients, 59.2% of them received metal stents. Primary tumor resection was performed in 60 (16.9%) patients. Enteral or biliary bypass was done in 35 and 49 patients, respectively. In a multivariate Cox-regression model, smoking status and presence of gemcitabine-based chemotherapy were identified as independent predictors for overall survival. We report the first data from a large cohort of Hungarian pancreatic cancer patients. We identified smoking status and chemotherapy as independent predictors in this cohort.

    Full Text Available Acute pancreatitis (AP is an inflammatory disease presenting from mild localized inflammation to severe infected necrotic pancreatic tissue. In the literature, there are a few cases of hypothermia-induced AP. However, the association between hypothermia and AP is still a myth. Generally, mortality from acute pancreatitis is nearly 3–6%. Here, we present a 40-year-old chronic alcoholic female who presented with acute pancreatitis induced by transient hypothermia. A 40-year-old chronic alcoholic female was hypothermic at 81°F on arrival which was improved to 91.7°F with warming blanket and then around 97°F in 8 h. Laboratory tests including complete blood count, lipid panel, and comprehensive metabolic panels were within the normal limit. Serum alcohol level was 0.01, amylase 498, lipase 1,200, ammonia 26, serum carboxyhemoglobin level 2.4, and β-HCG was negative. The entire sepsis workup was negative. During rewarming period, she had one episode of witnessed generalized tonic-clonic seizure. It was followed by transient hypotension. Fluid challenge was successful with 2 L of normal saline. Sonogram (abdomen showed fatty liver and trace ascites. CAT scan (abdomen and pelvis showed evidence of acute pancreatitis without necrosis, peripancreatic abscess, pancreatic mass, or radiopaque gallstones. The patient was managed medically and later discharged from the hospital on the 4th day as she tolerated a normal low-fat diet. In our patient, transient hypothermia from chronic alcohol abuse and her social circumstances might predispose to microcirculatory disturbance resulting in acute pancreatitis. Early and aggressive fluid resuscitation prevents complications.

El problema se focaliza en ejemplares de 0,2 a 1 g y las causas apuntan a procesos de acidificación del pH del agua y a la presencia de ciertos metales pesados, entre los cuales destaca el aluminio, que alcanza concentraciones más allá de los rangos de tolerancia de los peces. La información científica indica que concentraciones de 5 mg Ca L-1 en el afluente son suficientes para mantener a salvo los peces del efectos tóxico del aluminio. Sin embargo, los problemas en la producción de alevines de salmón indican que se requiere un mayor conocimiento científico y evidencia experimental que soporte el desarrollo de procesos y tecnologías para el tratamiento de los afluentes de las pisciculturas chilenas. En este trabajo se evaluó el efecto de cuatro concentraciones de calcio (0, 5, 10 y 20 mg Ca L-1 sobre la toxicidad aguda de 500 μg Al L-1 en alevines de trucha arcoiris (Oncorhynchus mykiss de 0,1 g en agua de cultivo a pH 5, 6 y 7. El objetivo del trabajo fue determinar la dosis de calcio que reduce la toxicidad aguda de aluminio y los tiempos mínimos de reacción que podrían disponer los piscicultores para tomar medidas preventivas ante una concentración aguda de aluminio en el agua de cultivo. Los resultados indican que antes de 8 h de exposición a una concentración tóxica de aluminio los piscicultores deberían asegurar en el agua de cultivo una dosis superior a 10 mg Ca L-1 y un pH >6 como medida remedial para reducir el efecto de intoxicación aguda causada por aluminio.

    Pancreatic cancer, adenocarcinoma, generally rapidly progresses, and if a metastatic lesion is detected, chemotherapy is applied even in solitary metastasis. However, surgical resection for solitary metastasis have been reported to achieve long survival in some pancreatic cancer patients. In a prospective study of surgery for hepatic and lymph node oligometastasis of pancreatic cancer, long survival of 5 years or more was reported around 10%. Furthermore, longer survival and fewer rerecurrence were achieved with surgery in lung metastasis than in liver metastasis and loco-regional recurrence. Although there has been no establishment of concept or no consensus of treatment strategy for oligometastasis in pancreatic cancer, some patients with pancreatic cancer have long disease-free survival by surgery for oligometastasis. A population of pancreatic cancer patients who have benefits of surgery for oligometastasis should be identified, and it is necessary to establish treatments for oligometastasis as standard treatments in pancreatic cancer.

    Autoimmune pancreatitis (AIP) is a chronic fibroinflammatory disease of the pancreas that belongs to the spectrum of immunoglobulin G-subclass4-related diseases (IgG4-RD) and typically presents with obstructive jaundice. Idiopathic duct-centric pancreatitis (IDCP) is a closely related but distinct disease that mimics AIP radiologically but manifests clinically most commonly as recurrent acute pancreatitis in young individuals with concurrent inflammatory bowel disease. IgG4 levels are often elevated in AIP and normal in IDCP. Histologically, lymphoplasmacytic acinar inflammation and storiform fibrosis are seen in both. In addition, the histologic hallmark of IDCP is the granulocyte epithelial lesion: intraluminal and intraepithelial neutrophils in medium-sized and small ducts with or without granulocytic acinar inflammation often associated with destruction of ductal architecture. Initial treatment of both AIP and IDCP is with oral corticosteroids for duration of 4 weeks followed by a gradual taper. Relapses are common in AIP and relatively uncommon in IDCP, a relatively rare disease for which the natural history is not well understood. For patients with relapsing AIP, treatment with immunomodulators and more recently rituximab has been recommended. Although rare instances of pancreaticobiliary malignancy has been reported in patients with AIP, overall the lifetime risk of developing pancreatic cancer does not appear to be elevated.

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

    Despite the recent technological advances in imaging, abdominal ultrasonography continues to be the first diagnostic test indicated in patients with a suspicion of pancreatic disease, due to its safety, accessibility and low cost. It is an essential technique in the study of inflammatory processes, since it not only assesses changes in pancreatic parenchyma, but also gives an indication of the origin (bile or alcoholic). It is also essential in the detection and tracing of possible complications as well as being used as a guide in diagnostic and therapeutic punctures. It is also the first technique used in the study of pancreatic tumors, detecting them with a sensitivity of around 70% and a specificity of 90%.

    Data concerning the incidence and treatment of pancreatic fistula after necrosectomy in severe acute necrotizing pancreatitis (SAP) are scarce. Our aim was to assess the incidence of pancreatic fistula, and the feasibility and results of endoscopic transpapillary stenting (ETS) in patients with SAP after necrosectomy. From January 2009 to December 2012 twenty-nine consecutive patients with SAP and necrosectomy in Oulu University Hospital were enrolled into this study. Five patients died before ETS because of the rapid progress of the disease and were, therefore, excluded. ERP was performed for the remaining 24 patients demonstrating fistula in 22/24 patients (92 %). ETS was successful in 23 patients and the fistula closed in all of them after a median of 82 (2-210) days with acceptable morbidity and no procedure-related mortality. All patients after necrosectomy for SAP seem to have internal or external pancreatic fistula. EST aimed at internal drainage of the necrosectomy cavity is a feasible and effective therapy in these patients.

    Purpose of review In this article, we review important advances in our understanding of the mechanisms of pancreatitis. Recent Findings The relative contribution of intra-pancreatic trypsinogen activation and NFκB activation, the two major early independent cellular events in the etiology of pancreatitis, have been investigated using novel genetic models. Trypsinogen activation has traditionally held the spotlight for many decades as it is believed to be the central pathogenic event of pancreatitis However, recent experimental evidence points to the role of trypsin activation in early acinar cell damage but not in the inflammatory response of acute pancreatitis through NFκB activation. Further, chronic pancreatitis in the caerulein model develops independently of typsinogen activation. Sustained activation of the NFκB pathway, but not persistent intra-acinar expression of active trypsin, was shown to result in chronic pancreatitis. Calcineurin-NFAT signaling was shown to mediate downstream effects of pathologic rise in intracellular calcium. IL-6 was identified as a key cytokine mediating pancreatitis-associated lung injury. Summary Recent advances challenge the long-believed trypsin-centered understanding of pancreatitis. It is becoming increasingly clear that activation of intense inflammatory signaling mechanisms in acinar cells is crucial to the pathogenesis of pancreatitis, which may explain the strong systemic inflammatory response in pancreatitis.

    Pancreatic cancer is the fourth comment cause of cancer-related death in men. Most patients with pancreatic cancer are diagnosed at advanced, non-resectable stage. Late detection, early metastases, difficult surgical approached, cancer resistant to systemic chemo and radiotherapy - all contribute to its in faust prognosis. Only about 5 % of patients will live 5 years after diagnosis. Gemcitabine - based combination treatments is the standard for advanced pancreatic cancer. The combination of fluorouracil, folinic acid, irinotecan and oxaliplatin led to median survival of 11 months. No standard second-line treatment exists for pancreatic cancer. (author)

    Impaired glucose tolerance or frank diabetes mellitus is known to occur more frequently in patients with pancreatic cancer than in the general population. At the time of the diagnosis of pancreatic cancer, more than 70% of patients taking the glucose tolerance test show diabetes or impaired glucose tolerance (1). Relationship among diabetes mellitus and pancreatic cancer is vague but sure, although neither the nature nor the sequence of the possible cause – effect relationship has been established. The reason for the high frequency of glucose intolerance in patients with pancreatic cancer remains controversial. (author)

    To study the outcome of acute collections occurring in patients with acute pancreatitis BACKGROUND:: There are limited data on natural history of acute collections arising after acute pancreatitis (AP). Consecutive patients of AP admitted between July 2011 and December 2012 were evaluated by imaging for development of acute collections as defined by revised Atlanta classification. Imaging was repeated at 1 and 3 months. Spontaneous resolution, evolution, and need for intervention were assessed. Of the 189 patients, 151 patients (79.9%) had acute collections with severe disease and delayed hospitalization being predictors of acute collections. Thirty-six patients had acute interstitial edematous pancreatitis, 8 of whom developed acute peripancreatic fluid collections, of which 1 evolved into pseudocyst. Among the 153 patients with acute necrotizing pancreatitis, 143 (93.4%) developed acute necrotic collection (ANC). Twenty-three of 143 ANC patients died, 21 had resolved collections, whereas 84 developed walled-off necrosis (WON), with necrosis >30% (P = 0.010) and Computed Tomographic Severity Index score ≥7 (P = 0.048) predicting development of WON. Of the 84 patients with WON, 8 expired, 53 patients required an intervention, and 23 were managed conservatively. Independent predictors of any intervention among all patients were Computed Tomographic Severity Index score ≥7 (P 7 days (P = 0.04). Patients with severe AP and delayed hospitalization more often develop acute collections. Pancreatic pseudocysts are a rarity in acute interstitial pancreatitis. A majority of patients with necrotising pancreatitis will develop ANC, more than half of whom will develop WON. Delay in hospitalization and higher baseline necrosis score predict need for intervention.

    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 mole melanoma, and Peutz-Jeghers and Lynch syndromes. 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.

    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 may lead to steatorrhea, enteric hyperoxaluria, and kidney damage. However, the prevalence and determinants of hyperoxaluria in chronic pancreatitis patients as well as its association with renal function decline have not been investigated.We performed an observational study. Urine oxalate to creatinine ratio was assessed on 2 independent random urine samples in consecutive adult patients with chronic pancreatitis followed at the outpatient clinic from March 1 to October 31, 2012. Baseline characteristics and annual estimated glomerular filtration rate (eGFR) change during follow-up were compared between patients with hyper- and normo-oxaluria.A total of 48 patients with chronic pancreatitis were included. The etiology of the disease was toxic (52%), idiopathic (27%), obstructive (11%), autoimmune (6%), or genetic (4%). Hyperoxaluria (defined as urine oxalate to creatinine ratio >32 mg/g) was found in 23% of patients. Multivariate regression analysis identified clinical steatorrhea, high fecal acid steatocrit, and pancreatic atrophy as independent predictors of hyperoxaluria. Taken together, a combination of clinical steatorrhea, steatocrit level >31%, and pancreatic atrophy was associated with a positive predictive value of 100% for hyperoxaluria. On the contrary, none of the patients with a fecal elastase-1 level >100 μg/g had hyperoxaluria. Longitudinal evolution of eGFR was available in 71% of the patients, with a mean follow-up of 904 days. After adjustment for established determinants of renal function decline (gender, diabetes, bicarbonate level, baseline eGFR, and proteinuria), a urine oxalate to creatinine ratio >32 mg/g was associated with a higher risk of eGFR decline.Hyperoxaluria is highly prevalent in patients with chronic pancreatitis and associated with faster decline in renal function. A high urine oxalate to creatinine ratio in patients with chronic pancreatitis is best predicted by clinical steatorrhea, a high acid

    Discriminating between autoimmune pancreatitis (AIP), chronic pancreatitis (CP), and pancreatic ductal adenocarcinoma (PDAC) can be challenging. In this retrospective study, levels of serum and tissue cytokines were analyzed as part of the clinical strategy for the preoperative differentiation between AIP and PDAC. The identification of differential cytokine profiles may help to prevent unnecessary surgical resection and allow optimal treatment of these pathologies. To compare the cytokine profiles of AIP, CP, and PDAC patients, serum and pancreatic tissue homogenates were subjected to multiplex analysis of 17 inflammatory mediators. In total, serum from 73 patients, composed of 29 AIP (14 AIP-1 and 15 AIP-2), 17 CP, and 27 PDAC, and pancreatic tissue from 36 patients, including 12 AIP (six AIP-1 and six AIP-2), 12 CP, and 12 PDAC, were analyzed. Comparing AIP and PDAC patients' serum, significantly higher concentrations were found in AIP for interleukins IL-1β, IL-7, IL-13, and granulocyte colony-stimulating factor (G-CSF). G-CSF also allowed discrimination of AIP from CP. Furthermore, once AIP was divided into subtypes, significantly higher serum levels for IL-7 and G-CSF were measured in both subtypes of AIP and in AIP-2 for IL-1β when compared to PDAC. G-CSF and TNF-α were also significantly differentially expressed in tissue homogenates between AIP-2 and PDAC. The cytokines IL-1β, IL-7, and G-CSF can be routinely measured in patients' serum, providing an elegant and non-invasive approach for differential diagnosis. G-CSF is a good candidate to supplement the currently known serum markers in predictive tests for AIP and represents a basis for a combined blood test to differentiate AIP and particularly AIP-2 from PDAC, enhancing the possibility of appropriate treatment.

  16. Animal models for investigating chronic pancreatitis

    Science.gov (United States)

    2011-01-01

    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. PMID:22133269

    Full Text Available Introduction: The association of acute viral hepatitis and acute pancreatitis is well described. This study was conducted to find out the frequency of pancreatic involvement in acute viral hepatitis in the Nepalese population. Methods: Consecutive patients of acute viral hepatitis presenting with severe abdominal pain between January 2005 and April 2010 were studied. Patients with history of significant alcohol consumption and gall stones were excluded. Acute viral hepatitis was diagnosed by clinical examination, liver function test, ultrasound examination and confirmed by viral serology. Pancreatitis was diagnosed by clinical presentation, biochemistry, ultrasound examination and CT scan. Results: Severe abdominal pain was present in 38 of 382 serologically-confirmed acute viral hepatitis patients. Twenty five patients were diagnosed to have acute pancreatitis. The pancreatitis was mild in 14 and severe in 11 patients. The etiology of pancreatitis was hepatitis E virus in 18 and hepatitis A virus in 7 patients. Two patients died of complications secondary to shock. The remaining patients recovered from both pancreatitis and hepatitis on conservative treatment. Conclusions: Acute pancreatitis occurred in 6.5 % of patients with acute viral hepatitis. Cholelithiasis and gastric ulcers are the other causes of severe abdominal pain. The majority of the patients recover with conservative management. Keywords: acute viral hepatitis, acute pancreatitis, pain abdomen, hepatitis E, hepatitis A, endemic zone

    Full Text Available Postpolypectomy bleeding and perforation are the most common complications of colonoscopy. A case of acute pancreatitis and ileus after colonoscopy is described. A 60-year-old woman underwent a gastroscopy and colonoscopy for investigation of iron deficiency anemia. Gastroscopy was normal; however, the colonoscope could not be advanced beyond the splenic flexure due to a tight angulation. Two polypectomies were performed in the descending colon. After the procedure, the patient developed a distended, tender abdomen. Bloodwork was remarkable for an elevated amylase level. An abdominal x-ray and computed tomography scan showed pancreatitis (particularly of the tail, a dilated cecum and a few air-fluid levels. The patient improved within 24 h of a repeat colonoscopy and decompression tube placement. The patient had no risk factors for pancreatitis. The causal mechanism of pancreatitis was uncertain but likely involved trauma to the tail of the pancreas during the procedure. Our patient developed ileus, likely secondary to pancreatitis. The present case is the first report of clinical pancreatitis and ileus associated with colonoscopy.

    Abstract Few data are present in the literature on the relationship between atorvastatin use and acute pancreatitis. The aim of this study was to explore this issue in Taiwan. Using representative claims data established from the Taiwan National Health Insurance Program, this case–control study consisted of 5810 cases aged 20 to 84 years with a first-time diagnosis of acute pancreatitis during the period 1998 to 2011and 5733 randomly selected controls without acute pancreatitis. Both cases and controls were matched by sex, age, comorbidities, and index year of diagnosing acute pancreatitis. Subjects who at least received 1 prescription for other statins or nonstatin lipid-lowering drugs were excluded from the study. If subjects never had 1 prescription for atorvastatin, they were defined as never use of atorvastatin. Current use of atorvastatin was defined as subjects whose last remaining 1 tablet of atorvastatin was noted ≤7 days before the date of diagnosing acute pancreatitis. Late use of atorvastatin was defined as subjects whose last remaining 1 tablet of atorvastatin was noted >7 days before the date of diagnosing acute pancreatitis. The odds ratio with 95% confidence interval of acute pancreatitis associated with atorvastatin use was calculated by using the logistic regression analysis. The logistic regression analysis revealed that the odds ratio of acute pancreatitis was 1.67 for subjects with current use of atorvastatin (95% confidence interval 1.18, 2.38), when compared with subjects with never use of atorvastatin. The odds ratio decreased to 1.15 for those with late use of atorvastatin (95% confidence interval 0.87, 1.52), but without statistical significance. Current use of atorvastatin is associated with the diagnosis of acute pancreatitis. Clinically, clinicians should consider the possibility of atorvastatin-associated acute pancreatitis when patients present with a diagnosis of acute pancreatitis without a definite etiology but are taking

Apresentamos o relato da evolução da gestação de uma paciente portadora de hipertrigliceridemia grave que havia apresentado pancreatite aguda dois meses antes da fecundação. Foi tratada durante o pré-natal com dieta e 3,0 g de ácidos graxos de cadeia ômega-3 (ácidos eicosapentaenóico 14% e docosahexaenóico 11,13%. Os níveis de triglicerídeos foram mantidos abaixo de 800 mg/dl, sendo este limite considerado seguro para evitar o desenvolvimento de pancreatite aguda. A gestação evoluiu, sem intercorrências, para parto vaginal, a termo. O recém-nato não apresentou alterações morfológicas ao nascimento. Concluímos que, nesta paciente grávida e portadora de hipertrigliceridemia grave, uma dieta adequada e o emprego de ácidos graxos de cadeia ômega-3 foram eficazes em prevenir a pancreatite aguda. Esta abordagem terapêutica pode ser uma alternativa para as gestantes portadoras de hipertrigliceridemia familiar.Severe hypertriglyceridemia during pregnancy rarely occurs but it frequently produces complications, such as acute pancreatitis, a serious health risk both for the mother and the fetus. The treatment of a patient who had had acute pancreatitis due to hypertriglyceridemia (triglyceridemia = 5100 mg/dl two months before fecundation is presented in this paper. During gestation, bezafibrate was substituted for 3.0 g omega-3 fatty acids (14% eicosapentaenoic and 11.13% docosahexaenoic acids. With this therapy, the triglyceride levels were maintained below 800 mg/dl, which is considered to be the safe limit to avoid acute pancreatitis. No complication occurred during pregnancy, the patient delivered vaginally (40 weeks, and the newborn (3075 g did not present any morphological alterations. We conclude that an adequate diet and the

    Chronic pancreatitis has been considered over the past years as a single disease, alcohol-induced and different from acute pancreatitis, in terms of etiology and prognosis. Actually, the introduction of a new concept of chronic pancreatitis, now considered as a fibroinflammatory process caused by multiple factors (toxic-metabolic, genetic, immunologic, obstructive), allow to better understand the pathogenesis of this complex disease. Furthermore, the discover of peculiar forms of chronic pancreatitis (autoimmune, paraduodenal, associated to gene mutations), different in term of clinical aspects, findings at imaging, prognosis and therapy, radically changed the concept of the disease. In this brief review, we described the impact of this new concept in the comprehension of pathogenesis, in the definition of peculiar forms of chronic pancreatitis, and in the clinical and therapeutic approach of chronic pancreatitis.

    The purpose of this study was to characterize the incidence, clinical features, and prognosis of acute pancreatitis in cats with hepatic lipidosis. Of 13 cats histologically diagnosed with hepatic lipidosis between July 1988, and November 1989, 5(38%) were also histologically diagnosed with acute pancreatitis. In cats with hepatic lipidosis alone, the signalment, history, physical examination, and clinicopathologic findings were generally indistinguishable from those of cats with concurrent acute pancreatitis except that cats with acute pancreatitis were more likely to be cachectic and to have coagulation abnormalities. Hepatomegaly was seen on abdominal radiographs in both groups. Of the 5 cats with concurrent acute pancreatitis, abdominal ultrasonography detected 1 cat with a hypoechoic pancreas and 5 with peritoneal effusion; those abnormalities were not seen in cats without concurrent acute pancreatitis. Cats with concurrent acute pancreatitis had only a 20% recovery rate, compared with a 50% recovery rate in cats with hepatic lipidosis alone. We conclude that cats with hepatic lipidosis should be rigorously evaluated for concurrent acute pancreatitis because of 1) the rate of disease coincidence, 2) the inability of signalment, history, physical examination, and clinicopathologic findings to adequately distinguish between hepatic lipidosis and acute pancreatitis, 3) the worse prognosis associated with concurrent acute pancreatitis, and 4) the opposing nutritional strategies for hepatic lipidosis and acute pancreatitis.

    Gastrointestinal toxicity is uncommon among patients treated with angiotensin II receptor antagonists. A 58-year-old man presented with nausea, vomiting and constant pain in the epigastrium that radiated to the flanks. He received treatment with valsartan (160 mg daily) for hypertension. The clinical, biochemical and radiological findings were compatible with a diagnosis of acute pancreatitis. After the patient achieved a clinical and biochemical recovery, the valsartan therapy was started again. Six weeks later, he returned to the hospital with an attack of pancreatitis. Subsequently, he returned with repeated attacks of pancreatitis twice, and the valsartan was discontinued. Ten months after the treatment, the patient had no complaints. When severe abdominal symptoms occur for no apparent reason during treatment with valsartan, a diagnosis of pancreatitis should be considered.

    Precepts about acute pancreatitis, necrotizing pancreatitis, and pancreatic fluid collections or pseudocyst rarely include the impact of pancreatic ductal injuries on their natural course and outcomes. We previously examined and established a system to categorize ductal changes. We sought a unifying concept that may predict course and direct therapies in these complex patients. We use our system categorizing ductal changes in pseudocyst of the pancreas and severe necrotizing pancreatitis (type I, normal duct; type II, duct stricture; type III, duct occlusion or "disconnected duct"; and type IV, chronic pancreatitis). From 1985 to 2006, a policy was implemented of routine imaging (cross-sectional, endoscopic retrograde cholangiopancreatography, or magnetic resonance cholangiopancreatography). Clinical outcomes were measured. Among 563 patients with pseudocyst, 142 resolved spontaneously (87% of type I, 5% of type II, and no type III, and 3% of type IV). Percutaneous drainage was successful in 83% of type I, 49% of type II, and no type III or type IV. Among 174 patients with severe acute pancreatitis percutaneous drainage was successful in 64% of type I, 38% of type II, and no type III. Operative debridement was required in 39% of type I and 83% and 85% of types II and III, respectively. Persistent fistula after debridement occurred in 27%, 54%, and 85% of types I, II, and III ducts, respectively. Late complications correlated with duct injury. Pancreatic ductal changes predict spontaneous resolution, success of nonoperative measures, and direct therapies in pseudocyst. Ductal changes also predict patients with necrotizing pancreatitis who are most likely to have immediate and delayed complications.

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

    The diagnosis of traumatic pancreatic injury in the acute stage is difficult to establish blood tests and abdominal findings alone. Moreover, to determine treatment strategies, it is important not only that a pancreatic injury is diagnosed but also whether a pancreatic ductal injury can be found. At our center, to diagnose isolated pancreatic injuries, we actively perform endoscopic retrograde pancreatography (ERP) in addition to abdominal CT at the time of admission. For cases with complications such as abdominal and other organ injuries, we perform a laparotomy to ascertain whether a pancreatic duct injury is present. In regard to treatment options, for grade III injuries to the pancreatic body and tail, we basically choose distal pancreatectomy, but we also consider the Bracy method depending on the case. As for grade III injuries to the pancreatic head, we primarily choose pancreaticoduodenectomy, but also apply drainage if the situation calls for it. However, pancreatic injuries are often complicated by injuries of other regions of the body. Thus, diagnosis and treatment of pancreatic injury should be based on a comprehensive decision regarding early prioritization of treatment, taking hemodynamics into consideration after admission, and how to minimize complications such as anastomotic leak and pancreatic fistulas.

    Chronic pancreatitis is an ongoing inflammatory process that may over time lead to mal digestion, malabsorption and diabetic syndrome. Identification of risk (etiological) factors based on classifications TIGAR-O or later M-ANNHEIM. These factors (environmental and / or genetic) leads to failure of the stability of the digestive and lysosomal enzymes in the acinar cells, resulting in premature activation of digestive enzymes in the pancreas, and repeated nekroinflamation and fibrosis. The incidence has of the upward trend. Clinically the disease manifests itself in most cases with pain and possibly with nonspecific dyspeptic troubles. Decisive role in the diagnosis playing imaging methods, trans abdominal ultrasonography, computed tomography, magnetic resonance imaging, magnetic cholangiopancretography and foremost endoscopic ultrasonography, which has the highest sensitivity and specificity. Endoscopic retrograde cholangiopancreatography is currently regarded as a method for therapy, not for diagnosis. Less importance is now attached to a functional test. Symptomatic treatment is usually conservative. Abstinence is necessary, easily digestible, but calorie-rich diet with reduced fat. Most patients needed treatment with analgesics. In case of insufficient effect of analgesics is necessary to consider endoscopic therapy or surgery. If the external secretory insufficiency is present are served pancreatic extracts. Diabetic syndrome requires insulin delivery. Generally, chronic pancreatitis is a disease treatable but incurable. Proportion of patients are also dying of pancreatic cancer. (author)

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

    Hormone-stimulated pancreatic function tests (PFTs) are considered the gold standard for measuring pancreatic exocrine function. PFTs involve the administration of intravenous secretin or cholecystokinin, followed by collection and analysis of pancreatic secretions. Because exocrine function may decline in the earliest phase of pancreatic fibrosis, PFTs are considered accurate for diagnosing chronic pancreatitis. Unfortunately, these potentially valuable tests are infrequently performed except at specialized centers, because they are time consuming and complicated. To overcome these limitations, endoscopic PFT methods have been developed which include aspiration of pancreatic secretions through the suction channel of the endoscope. The secretin endoscopic pancreatic function test (ePFT) involves collection of duodenal aspirates at 15, 30, 45 and 60 min after secretin stimulation. A bicarbonate concentration greater than 80 mmol/L in any of the samples is considered a normal result. The secretin ePFT has demonstrated good sensitivity and specificity compared with various reference standards, including the "Dreiling tube" secretin PFT, endoscopic ultrasound, and surgical histology. Furthermore, a standard autoanalyzer can be used for bicarbonate analysis, which allows the secretin ePFT to be performed at any hospital. The secretin ePFT may complement imaging tests like endoscopic ultrasound (EUS) in the diagnosis of early chronic pancreatitis.This paper will review the literature validating the use of ePFT in the diagnosis of exocrine insufficiency and chronic pancreatitis. Newer developments will also be discussed, including the feasibility of combined EUS/ePFT, the use of cholecystokinin alone or in combination with secretin, and the discovery of new protein and lipid pancreatic juice biomarkers which may complement traditionalfluid analysis.

    Full Text Available Background & Aims: The pathogenic mechanism of pancreatitis is poorly understood. Recent evidence implicates defective autophagy in pancreatitis responses; however, the pathways mediating impaired autophagy in pancreas remain largely unknown. Here, we investigate the role of lysosome associated membrane proteins (LAMPs in pancreatitis. Methods: We analyzed changes in LAMPs in experimental models and human pancreatitis, and the underlying mechanisms: LAMP deglycosylation and degradation. LAMP cleavage by cathepsin B (CatB was analyzed by mass spectrometry. We used mice deficient in LAMP-2 to assess its role in pancreatitis. Results: Pancreatic levels of LAMP-1 and LAMP-2 greatly decrease across various pancreatitis models and in human disease. Pancreatitis does not trigger the LAMPs’ bulk deglycosylation but induces their degradation via CatB-mediated cleavage of the LAMP molecule close to the boundary between luminal and transmembrane domains. LAMP-2 null mice spontaneously develop pancreatitis that begins with acinar cell vacuolization due to impaired autophagic flux, and progresses to severe pancreas damage characterized by trypsinogen activation, macrophage-driven inflammation, and acinar cell death. LAMP-2 deficiency causes a decrease in pancreatic digestive enzymes content, and stimulates the basal and inhibits cholecystokinin-induced amylase secretion by acinar cells. The effects of LAMP-2 knockout and acute cerulein pancreatitis overlap, which corroborates the pathogenic role of LAMP decrease in experimental pancreatitis models. Conclusions: The results indicate a critical role for LAMPs, particularly LAMP-2, in maintaining pancreatic acinar cell homeostasis and provide evidence that defective lysosomal function, resulting in impaired autophagy, leads to pancreatitis. Mice with LAMP-2 deficiency present a novel genetic model of human pancreatitis caused by lysosomal/autophagic dysfunction. Keywords: Amylase Secretion, Autophagy

    Full Text Available Treatment of pain in chronic pancreatitis includes medical, endoscopic and surgical therapy. Medical treatment may involve the use of analgesics, pancreatic enzymes, antioxidants and removal of risk factors. However, a substantial number of patients do not experience pain relief with medical treatment, and those with local complications cannot be treated medically indefinitely. These require endoscopic or surgical therapy. Endoscopic therapy has involved the use of a pancreatic sphincterotomy, b stent placement, c nasopancreatic drainage, d pseudocyst drainage, e extra corporeal shock wave lithotripsy (ESWL, and f dilatation of strictures. The current options for surgical therapy include: a partial pancreatic resections, b extended pancreatic drainage procedures (which involve additional subtotal resection of the head or a deep coring out of the head, or c pure pancreatic drainage procedures. In effect surgical procedures provide a more thorough drainage of the ductal system than pancreatic stent placement. This is especially true in the complex ductal arrangement of the head of the pancreas, where simple drainage of the duct or stent placement by endoscopy is unlikely to provide thorough drainage and relief of symptoms.

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

    Objective: To study the MR cholangiopancreatography (MRCP) characteristics of different pancreatic diseases, and to identify the diagnostic value of MRCP for pancreatic diseases. Methods: One hundred and eleven patients with suspected pancreatic diseases underwent MRCP examination. The MRCP sequences included thick-slice turbo spin echo (TSE) and thin-slice half-Fourier acquisition single shot turbo spin echo (HASTE) sequences. The pancreatic diseases included pancreatic carcinoma (n=46), chronic pancreatitis (n=39), peri-ampullar carcinoma (n=23), and choledocholith (n=3). Results: (1) The abnormal manifestation of pancreatic duct was observed in 37 cases of pancreatic carcinoma, 24 cases of chronic pancreatitis, and 12 cases of peri-ampullar carcinoma. Dilated pancreatic duct with smooth and regular caliber was observed in 33 cases of pancreatic carcinoma, 0 case of chronic pancreatitis, and 12 cases of peri-ampullar carcinoma, and statistical analysis showed significant difference (χ 2 =57.911, P 2 =60.343, P 2 =61.217, P 2 =34.654, P 2 =54.593, P<0.01). Conclusion: Different MRI characteristics were observed in various pancreatic diseases respectively. MRCP can show the subtle differences among the pancreatic diseases, and is very helpful in the diagnosis and differential diagnosis of pancreatic diseases

    Tropical chronic pancreatitis is a form of idiopathic chronic pancreatitis that has not previously been described in Spain. Typically it is related to dietary factors and malnutrition, although genetic factors may also play a significant role in the development of the disease. We report a case of chronic tropical pancreatitis in a 27-year-old woman from the Dominican Republic domiciled in Spain since 1992. The patient was admitted to our hospital for acute pancreatitis that fulfilled the diagnostic criteria (clinical and radiological) for chronic tropical pancreatitis. This case has led us to review this uncommon entity. Because of the increasing number of immigrants from tropical countries, chronic tropical pancreatitis will probably need to be taken into account in the differential diagnosis of chronic pancreatitis in our patients.

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

  7. Hedgehog signaling and therapeutics in pancreatic cancer.

    Kelleher, Fergal C

    2012-02-01

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

  8. Pancreatic Stones: Treat or Ignore?

    DA Howell

    1999-01-01

    Full Text Available Painful, chronic pancreatitis is of complex etiology, but increasing clinical experience suggests that removal of pancreatic duct stones in many cases significantly improves patients’ symptoms. The development and refinement of therapeutic endoscopic retrograde choledochopancreatography have permitted improved access to the pancreatic duct, which makes the development of new techniques of stone fragmentation and fragment removal a much more successful nonsurgical intervention. A major step forward has been the understanding of the safety and efficacy of pancreatic sphincterotomy, which is necessary for the removal of these difficult stones. The recognition that extracorporeal shock wave lithotripsy can be delivered safely with good efficacy has revolutionized the nonsurgical management of pancreatic duct stones. Nevertheless, advanced and sophisticated therapeutic endoscopy is necessary to achieve clearance of the duct, which can generally be accomplished in the majority of selected patients. State-of-the-art treatments are described, and some new approaches using pancreatoscopy and electrohydrolic lithotripsy are discussed. Newly recognized long term complications are reviewed. Finally, it must be recognized that chronic pancreatitis is an ongoing disease that does not have a simple treatment or cure, and frequently represents a process of remissions and relapses requiring interventions and problem solving.

    Early detection of pancreatic and periampullary neoplasms is critical to improve their clinical outcome. The present authors previously demonstrated that DNA hypermethylation of adenomatous polyposis coli (APC), histamine receptor H2 (HRH2), cadherin 13 (CDH13), secreted protein acidic and cysteine rich (SPARC) and engrailed-1 (EN-1) promoters is frequently detected in pancreatic tumor cells. The aim of the present study was to assess their prevalence in pancreatic juice of carcinomas of the pancreas and periampullary area. A total of 135 pancreatic juices obtained from 85 pancreatic cancer (PC), 26 ampullary carcinoma (AC), 10 intraductal papillary mucinous neoplasm (IPMN) and 14 chronic pancreatitis (CP) patients were analyzed. The methylation status of the APC, HRH2, CDH13, SPARC and EN-1 promoters was analyzed using methylation specific-melting curve analysis (MS-MCA). Kirsten rat sarcoma viral oncogene homolog (KRAS) mutations were also tested with allele-specific quantitative polymerase chain reaction amplification. Out of the 5 promoters analyzed, APC (71%) and HRH2 (65%) were the most frequently methylated in PC juice. APC methylation was also detected at a high frequency in AC (76%) and IPMN (80%), but only occasionally observed in CP (7%). APC methylation had a high sensitivity (71-80%) for all types of cancer analyzed. The panel (where a sample scored as positive when ≥2 markers were methylated) did not outperform APC as a single marker. Finally, KRAS detection in pancreatic juice offered a lower sensitivity (50%) and specificity (71%) for detection of any cancer. APC hypermethylation in pancreatic juice, as assessed by MS-MCA, is a frequent event of potential clinical usefulness in the diagnosis of pancreatic and periampullary neoplasms.

    Pancreatitis is an inflammatory disease of the pancreas characterized by dysregulated activity of digestive enzymes, necrosis, immune infiltration, and pain. Repeated incidence of pancreatitis is an important risk factor for pancreatic cancer. Legumain, a lysosomal cysteine protease, has been linked to inflammatory diseases such as atherosclerosis, stroke, and cancer. Until now, legumain activation has not been studied during pancreatitis. We used a fluorescently quenched activity-based probe to assess legumain activation during caerulein-induced pancreatitis in mice. We detected activated legumain by ex vivo imaging, confocal microscopy, and gel electrophoresis. Compared with healthy controls, legumain activity in the pancreas of caerulein-treated mice was increased in a time-dependent manner. Legumain was localized to CD68+ macrophages and was not active in pancreatic acinar cells. Using a small-molecule inhibitor of legumain, we found that this protease is not essential for the initiation of pancreatitis. However, it may serve as a biomarker of disease, since patients with chronic pancreatitis show strongly increased legumain expression in macrophages. Moreover, the occurrence of legumain-expressing macrophages in regions of acinar-to-ductal metaplasia suggests that this protease may influence reprogramming events that lead to inflammation-induced pancreatic cancer.

    We examined 20 prediagnostic CTs from 16 patients for whom the diagnosis of pancreatic cancer was delayed until full diagnostic CT was performed. Three radiologists independently reviewed the prediagnostic CTs along with 50 CTs of control subjects, including patients without pancreatic disease (n = 38) or with chronic pancreatitis without calcification visible on CT (n=12). The reviewers recorded the presence of biliary or pancreatic ductal dilation, interruption of the pancreatic duct, distal parenchymal atrophy, contour abnormality and focal hypoattenuation. Frequency, sensitivity and specificity of the significant findings were calculated. Logistic regression analysis was performed. Findings indicative of pancreatic cancer were seen on 85% (17/20) of the prediagnostic CTs. Patients with pancreatic cancer were significantly (p<0.05) more likely to show focal hypoattenuation, pancreatic duct dilation, interruption of the pancreatic duct, and distal parenchymal atrophy, with sensitivities and specificities of 75%/84%, 50%/78%, 45%/82% and 45%/96%, respectively. Focal hypoattenuation and distal parenchymal atrophy were the independent predictors of pancreatic cancer with odds ratios of 20.92 and 11.22, respectively. In conclusion, focal hypoattenuation and pancreatic duct dilation with or without interruption, especially when accompanied by distal parenchymal atrophy, were the most useful findings for avoiding delayed diagnosis of pancreatic cancer.

    Pancreatitis is associated with intraductal papillary mucinous neoplasm (IPMN). This association is in part due to inflammation from pancreatic ductal obstruction. Although the correlation between pancreatitis and the malignant potential of IPMN is unclear, the 2012 International Consensus Guidelines (ICG) consider pancreatitis a "worrisome feature." We hypothesized that serum pancreatic enzymes, markers of inflammation, are a better predictor of malignancy than pancreatitis in patients with IPMN. Between 1992 and 2012, 364 patients underwent resection for IPMN at a single university hospital. In the past decade, serum amylase and lipase were collected prospectively as an inflammatory marker in 203 patients with IPMN at initial surveillance and "cyst clinic" visits. The latest serum pancreatic enzyme values within 3 months preoperatively were studied. Pancreatitis was defined according to the 2012 revision of the Atlanta Consensus. Of the 203 eligible patients, there were 76 with pancreatitis. Pancreatitis was not associated with an increased rate of malignancy (P = .51) or invasiveness (P = .08). Serum pancreatic enzymes categorically outside of normal range (high or low) were also not associated with malignancy or invasiveness. In contrast, as a continuous variable, the higher the serum pancreatic enzymes were, the greater the rate of invasive IPMN. Of the 127 remaining patients without pancreatitis, serum pancreatic enzymes outside of normal range (low and high) were each associated with a greater rate of malignancy (P enzyme levels above normal range (high) were associated with a greater rate of invasiveness (P = .02). In patients with IPMN without a history of pancreatitis, serum pancreatic enzymes outside of the normal range are associated with a greater risk of malignancy. In patients with a history of pancreatitis, there is a positive correlation between the levels of serum pancreatic enzymes and the presence of invasive IPMN. These data suggest

    Materials and Methods. From January 1, 2004 to December, 2007 a total of 20 patients with pancreatic malignancies were retrospectively evaluated who underwent pancreatic surgery with synchronous resection of hepatic, adjacent organ, or peritoneal metastases for proven UICC stage IV periampullary cancer of the pancreas. Perioperative as well as clinicopathological parameters were evaluated. Results. There were 20 patients (9 men, 11 women; mean age 58 years identified. The primary tumor was located in the pancreatic head (n=9, 45%, in pancreatic tail (n=9, 45%, and in the papilla Vateri (n=2, 10%. Metastases were located in the liver (n=14, 70%, peritoneum (n=5, 25%, and omentum majus (n=2, 10%. Lymphnode metastases were present in 16 patients (80%. All patients received resection of their tumors together with metastasectomy. Pylorus preserving duodenopancreatectomy was performed in 8 patients, distal pancreatectomy in 8, duodenopancreatectomy in 2, and total pancreatectomy in 2. Morbidity was 45% and there was no perioperative mortality. Median postoperative survival was 10.7 months (2.6–37.7 months which was not significantly different from a matched-pair group of patients who underwent pancreatic resection for UICC adenocarcinoma of the pancreas (median survival 15.6 months; P=.1. Conclusion. Pancreatic resection for M1 periampullary cancer of the pancreas can be performed safely in well-selected patients. However, indication for surgery has to be made on an individual basis.

    Full Text Available Background. The prevalence of pancreatitis in children with digestive disorders is 5–25 %. Aim of research: to determine the prevalence of pancreatic pathology in children. Material and methods. The research was conducted on the basis of department of gastroenterology of Chernivtsi Regional Clinical Children’s Hospital during 2013–2015. Results. The overall prevalence of chronic pancreatitis in children of Chernivtsi region is 1.8 %. It should also be noted that 66 % of children with chronic gastroduodenitis and 100 % of children with duodenal bulb ulcer had ultrasound changes of pancreas. Signs of chronic pancreatitis were detected in 1 child with celiac disease and 4 children with lactose intolerance; 17 children had identified ultrasound signs of pancreatic fibrosis, and reduced elastase‑1 in stool, which can be considered as signs of chronic pancreatitis; 9 children had identified ultrasound signs of structural changes of pancreas, but the level of elastase‑1 was normal (patients with recurrent pancreatitis; 18 children had no ultrasound changes of pancreas and no deviation in the structure and the level of elastase‑1. Conclusion. The chronic pancreatitis in children is often associated with pain (epigastric paroxysmal pain with frequent changes of pain location, dyspeptic (often manifested by nausea and vo­miting and astheno-vegetative syndromes which are associated with disharmonious physical development. All patients with chronic pancreatitis were revealed to have focal or linear fibrotic changes in the parenchyma of the pancreas, nonspecific changes in coprogram and a significant reduction of elastase‑1 level in blood.

    To compare the value of the clinical criteria of Ranson, the classical tomographic criteria of Balthzar and the severity of illness index according to CT in predicting the development of complications of acute pancreatitis. A retrospective study was performed in 100 patients with clinical and analytical evidence of acute pancreatitis. All patients were assessed according to Ranson score at admission and 48 hours later, and contrast-enhanced abdominal CT was carried out. The tomographic images were analyzed on the basis of the classical criteria of Balthazar and the new CT severity of illness index, which includes the assessment of pancreatic necrosis, identified as the areas of the pancreas that are not enhanced by the administration of the contrast material. These three criteria were then correlated with onset of medical and surgical implications. Our findings show that, of the three criteria analyzed, the CT severity of illness index presents the greatest specificity, sensitivity and positive and negative predictive values in the prediction of complications of acute pancreatitis. We conclude that the inclusion of pancreatic necrosis in the tomographic study improves the early assessment of the prognosis of acute pancreatitis. (Author) 20 refs

    Purpose: Groove pancreatitis is a rare focal form of chronic pancreatitis that occurs in the pancreaticoduodenal groove between the major and minor papillae, duodenum and pancreatic head. Radiologic appearance and clinical presentation can result in suspicion of malignancy rendering pancreaticoduodenectomy inevitable. This study reports dual phase CT findings in a series of 12 patients with pathology proven groove pancreatitis. Materials and methods: Retrospective review of preoperative CT findings in 12 patients with histologically proven groove pancreatitis after pancreaticoduodenectomy. Size, location, attenuation, presence of mass or cystic components in the pancreas, groove and duodenum, calcifications, duodenal stenosis and ductal changes were recorded. Clinical data, laboratory values, endoscopic ultrasonographic and histopathological findings were collected. Results: Soft tissue thickening in the groove was seen in all patients. Pancreatic head, groove and duodenum were all involved in 75% patients. A discrete lesion in the pancreatic head was seen in half of the patients, most of which appeared hypodense on both arterial and venous phases. Cystic changes in pancreatic head were seen in 75% patients. Duodenal involvement was seen in 92% patients including wall thickening and cyst formation. The main pancreatic duct was dilated in 7 patients, with an abrupt cut off in 3 and a smooth tapering stricture in 4. Five patients had evidence of chronic pancreatitis with parenchymal calcifications. Conclusion: Presence of mass or soft tissue thickening in the groove with cystic duodenal thickening is highly suggestive of groove pancreatitis. Recognizing common radiological features may help in diagnosis and reduce suspicion of malignancy.

    In 2015, the Australasian Pancreatic Club (APC) published the Australasian guidelines for the management of pancreatic exocrine insufficiency (http://pancreas.org.au/2016/01/pancreatic-exocrine-insufficiency-guidelines). Pancreatic exocrine insufficiency (PEI) occurs when normal digestion cannot be sustained due to insufficient pancreatic digestive enzyme activity. This may be related to a breakdown, at any point, in the pancreatic digestive chain: pancreatic stimulation; synthesis, release or transportation of pancreatic enzymes; or synchronisation of secretions to mix with ingested food. Main recommendations: The guidelines provide advice on diagnosis and management of PEI, noting the following: A high prevalence of PEI is seen in certain diseases and conditions, such as cystic fibrosis, acute and chronic pancreatitis, pancreatic cancer and pancreatic surgery. The main symptoms of PEI are steatorrhoea or diarrhoea, abdominal pain, bloating and weight loss. These symptoms are non-specific and often go undetected and untreated. PEI diagnosis is predominantly based on clinical findings and the presence of underlying disease. The likelihood of PEI in suspected patients has been categorised into three groups: definite, possible and unlikely. If left untreated, PEI may lead to complications related to fat malabsorption and malnutrition, and have an impact on quality of life. Pancreatic enzyme replacement therapy (PERT) remains the mainstay of PEI treatment with the recommended adult initial enzyme dose being 25 000-40 000 units of lipase per meal, titrating up to a maximum of 75 000-80 000 units of lipase per meal. Adjunct acid-suppressing therapy may be useful when patients still experience symptoms of PEI on high dose PERT. Nutritional management by an experienced dietitian is essential. Changes in management as a result of these guidelines: These are the first guidelines to classify PEI as being definite, possible or unlikely, and provide a diagnostic algorithm to

    Highlights: • ARFI elastography of the pancreas is feasible. • Shear wave velocities in patients with acute or chronic pancreatitis or carcinoma are higher than those occurring in normal tissue. • ARFI values considerable overlap between different pathologies. - Abstract: Introduction: Acoustic Radiation Force Impulse (ARFI) elastography evaluates tissue stiffness non-invasively and has rarely been applied to pancreas examinations so far. In a prospective and retrospective analysis, ARFI shear wave velocities of healthy parenchyma, pancreatic lipomatosis, acute and chronic pancreatitis, adenocarcinoma and neuroendocrine tumor (NET) of the pancreas were evaluated and compared. Material and methods: In 95 patients ARFI elastography of the pancreatic head, and also of the tail for a specific group, was analysed retrospectively. Additionally, prospectively in 100 patients ARFI was performed in the head and tail of the pancreas. Results: A total of 195 patients were included in the study. Healthy parenchyma (n = 21) and lipomatosis (n = 30) showed similar shear wave velocities of about 1.3 m/s. Acute pancreatitis (n = 35), chronic pancreatitis (n = 53) and adenocarcinoma (n = 52) showed consecutively increasing ARFI values, respectively. NET (n = 4) revealed the highest shear wave velocities amounting to 3.62 m/s. ARFI elastography showed relevant differences between acute pancreatitis and chronic pancreatitis or adenocarcinoma. With a cut-off value of 1.74 m/s for the diagnosis of a malignant disease the sensitivity was 91.1% whereas the specificity amounted to 60.4%. Conclusion: ARFI shear wave velocities present differences in various pathologies of the pancreas. Acute and chronic pancreatitis as well as neoplastic lesions show high ARFI values. Very high elasticity values may indicate malignant disease of the pancreas. However, there is a considerable overlap between the entities.

    The diagnosis of chronic pancreatitis remains challenging in early stages of the disease. This report defines the diagnostic criteria useful in the assessment of patients with suspected and established chronic pancreatitis. All current diagnostic procedures are reviewed and evidence based statements are provided about their utility and limitations. Diagnostic criteria for chronic pancreatitis are classified as definitive, probable or insufficient evidence. A diagnostic (STEP-wise; S-survey, T-tomography, E-endoscopy and P-pancreas function testing) algorithm is proposed that proceeds from a non-invasive to a more invasive approach. This algorithm maximizes specificity (low false positive rate) in subjects with chronic abdominal pain and equivocal imaging changes. Futhermore, a nomenclature is suggested to further characterize patients with established chronic pancreatitis based on TIGAR-O (T-toxic, I-idiopathic, G-genetic, A- autoimmune, R-recurrent and O-obstructive) etiology, gland morphology (Cambridge criteria) and physiologic state (exocrine, endocrine function) for uniformity across future multi-center research collaborations. This guideline will serve as a baseline manuscript that will be modified as new evidence becomes available and our knowledge of chronic pancreatitis improves. PMID:25333398

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

    Full Text Available A 39-year-old man was referred to our hospital for the investigation of abdominal fluid collection. He was pointed out to have alcoholic chronic pancreatitis. Laboratory data showed inflammation and slightly elevated serum direct bilirubin and amylase. An abdominal computed tomography demonstrated huge fluid collection, multiple pancreatic pseudocysts and pancreatic calcification. The fluid showed a high level of amylase at 4,490 IU/l. Under the diagnosis of pancreatic ascites, endoscopic pancreatic stent insertion was attempted but was unsuccessful, so surgical treatment (Frey procedure and cystojejunostomy was performed. During the operation, a huge amount of fluid containing bile acid (amylase at 1,474 IU/l and bilirubin at 13.5 mg/dl was found to exist in the extraperitoneal space (over the peritoneum, but no ascites was found. His postoperative course was uneventful and he shows no recurrence of the fluid. Pancreatic ascites is thought to result from the disruption of the main pancreatic duct, the rupture of a pancreatic pseudocyst, or possibly leakage from an unknown site. In our extremely rare case, the pancreatic pseudocyst penetrated into the hepatoduodenal ligament with communication to the common bile duct, and the fluid flowed into the round ligament of the liver and next into the extraperitoneal space.

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

    The aim of this study was to explore the association between morphological and functional secretin-stimulated MRI parameters with hospitalization, quality of life (QOL), and pain in patients with chronic pancreatitis (CP). This prospective cohort study included 82 patients with CP. Data were obtained from clinical information, QOL, and pain as assessed by questionnaires (The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire and modified Brief Pain Inventory short form). Secretin-stimulated MRI morphological parameters included pancreatic gland volume, main pancreatic duct diameter, the modified Cambridge Classification of Duct Abnormality, apparent diffusion coefficient, fat signal fraction, and the pancreatic secretion volume as a functional parameter. The primary outcomes were time to first hospitalization related to the CP, as well as annual hospitalization frequency and duration. The secondary outcomes were pain severity, QOL, and pain interference scores. A main pancreatic duct diameter below 5 mm was associated with reduced time to first hospitalization (hazard ratio=2.06; 95% confidence interval: 1.02-4.17; P=0.043). Pancreatic secretion volume was correlated with QOL (r=0.31; P=0.0072) and pain interference score (r=-0.27; P=0.032), and fecal elastase was also correlated with QOL (r=0.28; P=0.017). However, functional and morphological findings were not related to pain intensity. Advanced pancreatic imaging techniques may be a highly sensitive tool for prognostication and monitoring of disease activity and its consequences.

    Acute pancreatitis is an inflammatory process of variable severity. Leucocytes are thought to play a key role in the development of pancreatitis and pancreatitis-associated lung injury. The interactions between inflammatory cells and their mediators are crucial for determining tissue damage. Monocyte chemoattractant protein-1 (or CCL-2), CCR-2 and CCR-4 are chemokines and chemokine receptors involved in leucocyte trafficking. The aim of the study was to evaluate the role of the CCL-2, CCR-2 and CCR-4 chemokine receptors in the pathogenesis of cerulein-induced pancreatitis and pancreatitis-associated lung injury. To address the role of CCL-2, CCR-2 and CCR-4 that attracts leucocytes cells in inflamed tissues, pancreatitis was induced by administering supramaximal doses of cerulein in mice that do not express CCL-2, CCR-2 or CCR-4. The severity of pancreatitis was measured by serum amylase, pancreatic oedema and acinar cell necrosis. Lung injury was quantitated by evaluating lung microvascular permeability and lung myeloperoxidase activity. Chemokine and chemokine-receptor expression were quantitated by real-time PCR. The nature of inflammatory cells invading the pancreas and lungs was studied by immunostaining. The authors have found that pancreas CCL-2 and CCR-2 levels rise during pancreatitis. Both pancreatitis and the associated lung injury are blunted, but not completely prevented, in mice deficient in CCL-2, whereas the deficiency in either CCR-2 or CCR-4 does not reduce the severity of both the pancreatitis and the lung injury. The amounts of neutrophils and monocyte/macrophages (MOMA)-2 cells were significantly lower in mice deficient in CCL-2 compared with their sufficient littermates. These results suggest that CCL-2 plays a key role in pancreatitis by modulating the infiltration by neutrophils and MOMA-2 cells, and that its deficiency may improve the outcome of the disease.

  15. Diagnostic value of computer tomography in chronic pancreatitis

    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 trauma treatment depends on pancreatic ductal injury. We examined the usefulness and problems of diagnostic imaging, such as enhanced CT, ERP, and CT after ERP, in pancreatic trauma. Subjects were 12 patients with pancreatic trauma treated in our hospital between April 1993 and March 2000. Enhanced CT was performed in 6 patients undergoing diagnostic imagings and ERP in 4 of the 6. Overall diagnostic accuracy of pancreatic ductal injury in enhanced CT was 16.7% and accuracy in ERP with CT after ERP was 100%. Intraoperative diagnosis of main pancreatic ductal injury was difficult in 1 of 2 patients in whom ERP failed. The importance of preoperative diagnostic imaging is thus clear. We expect that MRCP, recently evaluated in pancreatic disease diagnosis, will become a new pancreatic trauma modality. (author)

    The utilization of recent advances in molecular and genomic technologies and progress in pancreatic imaging techniques provided remarkable insight into genetic, environmental, immunologic, and pathobiological factors leading to chronic pancreatitis. Translation of these advances into clinical practice demands a reassessment of current approaches to diagnosis, classification, and staging. We conclude that an adequate pancreatic biopsy must be the gold standard against which all diagnostic approaches are judged. Although computed tomography remains the initial test of choice for the diagnosis of chronic pancreatitis, the roles of endoscopic retrograde pancreatography, endoscopic ultrasonography, and magnetic resonance imaging are considered. Once chronic pancreatitis is diagnosed, proper classification becomes important. Major predisposing risk factors to chronic pancreatitis may be categorized as either (1) toxic-metabolic, (2) idiopathic, (3) genetic, (4) autoimmune, (5) recurrent and severe acute pancreatitis, or (6) obstructive (TIGAR-O system). After classification, staging of pancreatic function, injury, and fibrosis becomes the next major concern. Further research is needed to determine the clinical and natural history of chronic pancreatitis developing in the context of various risk factors. New methods are needed for early diagnosis of chronic pancreatitis, and new therapies are needed to determine whether interventions will delay or prevent the progression of the irreversible damage characterizing end-stage chronic pancreatitis.

    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.

    Objective: To compare various CT signs of pancreatic carcinoma (PC) and inflammatory pancreatic mass (IPM), and to study the diagnostic value of these signs for distinguishing two diseases. Methods: Eigty-five patients with PC and IPM were proved by surgery, fine needle aspiration or other comprehensive methods. These patients underwent non-enhanced and enhanced CT scans. CT findings were analyzed retrospectively. The occurrance rates of various CT signs in these two diseases were analyzed with Fisher test and were compared with the corresponding clinical and operational results as well. Results: Among the 85 patients, 66 patients were proved to have PC, and 19 were proved to have IPM. In PC group, 58 were corerectly diagnosed with CT, 3 (4.5%) were misdiagnosed, and 5 (7.6%) were omitted. In IPM group, 9 were correctly diagnosed with CT and 10 (52.6%) were misdiagnosed. The CT findings were as follows: (1) Pancreatic mass with liver metastases, lymph node metastases, encased celiac arteries, and cancer emboli in portal veins just occurred in PC group. (2) The occurrence rates of mass over 3 cm in diameter, clear boundary, low-density area within the mass, pseudocysts, peripancreatic infiltration, ascites, and slight and moderate pancreatic-bile duct dilation in PC group were 90.91% (60/66), 15.15% (10/66), 54.55% (36/66), 10.61% (7/66), 4.55% (3/66), 22.73% (15/66), 24.24% (16/66), 45.45% (30/66), and 27.27% (18/66) respectively, the occurrence rates in IPM group were 94.74% (18/19), 15.79% (3/19), 52.63% (10/19), 15.79% (3/19), 15.79% (3/19), 21.05% (4/19), 31.58% (6/19), 21.05% (4/19), and 5.26% (1/19) respectively.

    Full Text Available Pazopanib is an oral angiogenesis inhibitor targeting vascular endothelial growth factor receptors, platelet-derived growth factor receptors, and c-Kit approved for the treatment of renal cell carcinoma and soft tissue sarcoma. Nonselective kinase inhibitors, such as sunitinib and sorafenib, are known to be associated with acute pancreatitis. There are few case reports of severe acute pancreatitis induced by pazopanib treatment. We present a case of severe acute pancreatitis caused by pazopanib treatment for cutaneous angiosarcoma. The patient was an 82-year-old female diagnosed with cutaneous angiosarcoma. She had been refractory to docetaxel treatment and began pazopanib therapy. Three months after pazopanib treatment, CT imaging of the abdomen showed the swelling of the pancreas and surrounding soft tissue inflammation without abdominal pain. After she continued pazopanib treatment for 2 months, she presented with nausea and appetite loss. Abdominal CT showed the worsening of the surrounding soft tissue inflammation of the pancreas. Serum amylase and lipase levels were 296 and 177 IU/l, respectively. She was diagnosed with acute pancreatitis induced by pazopanib treatment and was managed conservatively with discontinuation of pazopanib, but the symptoms did not improve. Subsequently, an abdominal CT scan demonstrated the appearance of a pancreatic pseudocyst. She underwent endoscopic ultrasound-guided pseudocyst drainage using a flared-end fully covered self-expandable metallic stent. Then, the symptoms resolved without recurrence. Due to the remarkable progress of molecular targeted therapy, the oncologist should know that acute pancreatitis was recognized as a potential adverse event of pazopanib treatment and could proceed to severe acute pancreatitis.

    Pancreatic ductal adenocarcinoma (PDAC) may present with acute and /or chronic pancreatitis due to pancreatic ductal obstruction causing diagnostic dilemma. The aim of this retrospective study was to investigate the outcome and prognosis of the patients of PDAC presenting with pancreatitis. From 1991 to 2009, 298 patients with PDAC that underwent surgical treatment were retrospectively studied and divided in two groups depending upon initial symptomatic presentation. Group A (n=254) comprised patients without pancreatitis while group B (n=44) patients presented with acute and/or chronic pancreatitis initially. All the patients in studied cohort were surgically treated. Mean age of group A was 63.1 years & for group B it was 62.9 years. Location of tumor was in head of the pancreas in 66.14% of group A patients (n=168) and 61.36% of group B patients (n=27). Although statistically insignificant, the patients in group B had overall better 5-year survival than the patients in group A (20% vs 15.9%). This retrospective study highlights the overall better survival of PDAC patients presenting with acute and/or chronic pancreatitis than those without as contrary to previous reports which stated the poor prognosis of PDAC patients if associated with underlying pancreatitis.

    Auditing is an important tool to identify practice variation and 'best practices'. The Dutch Pancreatic Cancer Audit is mandatory in all 18 Dutch centers for pancreatic surgery. Performance indicators and case-mix factors were identified by a PubMed search for randomized controlled trials (RCT's) and large series in pancreatic surgery. In addition, data dictionaries of two national audits, three institutional databases, and the Dutch national cancer registry were evaluated. Morbidity, mortality, and length of stay were analyzed of all pancreatic resections registered during the first two audit years. Case ascertainment was cross-checked with the Dutch healthcare inspectorate and key-variables validated in all centers. Sixteen RCT's and three large series were found. Sixteen indicators and 20 case-mix factors were included in the audit. During 2014-2015, 1785 pancreatic resections were registered including 1345 pancreatoduodenectomies. Overall in-hospital mortality was 3.6%. Following pancreatoduodenectomy, mortality was 4.1%, Clavien-Dindo grade ≥ III morbidity was 29.9%, median (IQR) length of stay 12 (9-18) days, and readmission rate 16.0%. In total 97.2% of >40,000 variables validated were consistent with the medical charts. The Dutch Pancreatic Cancer Audit, with high quality data, reports good outcomes of pancreatic surgery on a national level. Copyright © 2017 International Hepato-Pancreato-Biliary Association Inc.

    Pancreatitis, which is most generally described as any inflammation of the pancreas, is a serious condition that manifests in either acute or chronic forms. Chronic pancreatitis results from irreversible scarring of the pancreas, resulting from prolonged inflammation. Six major etiologies for chronic pancreatitis have been identified: toxic/ metabolic, idiopathic, genetic, autoimmune, recurrent and severe acute pancreatitis, and obstruction. The most common symptom associated with chronic pancreatitis is pain localized to the upper-to-middle abdomen, along with food malabsorption, and eventual development of diabetes. Treatment strategies for acute pancreatitis include fasting and short-term intravenous feeding, fluid therapy, and pain management with narcotics for severe pain or nonsteroidal anti-inflammatories for milder cases. Patients with chronic disease and symptoms require further care to address digestive issues and the possible development of diabetes. Dietary restrictions are recommended, along with enzyme replacement and vitamin supplementation. More definitive outcomes may be achieved with surgical or endoscopic methods, depending on the role of the pancreatic ducts in the manifestation of disease.

    Purpose: To define the evolution patterns of blunt pancreatic trauma, and to point out the CT features most significant for the diagnosis. Material and Methods: Ten cases of pancreatic trauma, observed over a period of about 10 years, were analyzed in retrospect. The cases were divided into 3 groups according to the time that had elapsed between trauma and first CT: Early phase (within 72 h: n=3/10); late phase (after 10 days: n=3/10); and following pancreatic drainage (n=4/10). Results: In the early phase, one case showed a blood collection surrounding the pancreatic head and duodenum, and displacing the mesenteric vessels to the left. In the 2 other cases it was possible to demonstrate a tear in the pancreas at the neck, perpendicular to the main pancreatic axis. In the late phase in all 3 cases, one cystic lesion was present at the site of the tear, either surrounding the gland or embedded - more or less deeply - within the parenchyma. One of the lesions subsided spontaneously; the 2 others required surgery. In the postoperative phase, an external fistula was demonstrated in 2 cases following percutaneous drainage of pancreatic cysts; the fistula was fed by a cystic lesion in the pancreatic neck. In the 2 other cases a pseudocyst developed. (orig.)

    Acute recurrent pancreatitis (ARP) refers to a clinical entity characterized by episodes of acute pancreatitis which occurs on more than one occasion. Recurrence of pancreatitis generally occurs in a setting of normal morpho-functional gland, however, an established chronic disease may be found either on the occasion of the first episode of pancreatitis or during the follow-up. The aetiology of ARP can be identified in the majority of patients. Most common causes include common bile duct stones or sludge and bile crystals; sphincter of oddi dysfunction; anatomical ductal variants interfering with pancreatic juice outflow; obstruction of the main pancreatic duct or pancreatico-biliary junction; genetic mutations; alcohol consumption. However, despite diagnostic technologies, the aetiology of ARP still remains unknown in up to 30% of cases: in these cases the term “idiopathic” is used. Because occult bile stone disease and sphincter of oddi dysfunction account for the majority of cases, cholecystectomy, and eventually the endoscopic biliary and/or pancreatic sphincterotomy are curative in most of cases. Endoscopic biliary sphincterotomy appeared to be a curative procedure per se in about 80% of patients. Ursodeoxycholic acid oral treatment alone has also been reported effective for treatment of biliary sludge. In uncertain cases toxin botulin injection may help in identifying some sphincter of oddi dysfunction, but this treatment is not widely used. In the last twenty years, pancreatic endotherapy has been proven effective in cases of recurrent pancreatitis depending on pancreatic ductal obstruction, independently from the cause of obstruction, and has been widely used instead of more aggressive approaches.

    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.

    Estrogen, whether therapeutic or physiologic, can cause hypertriglyceridemia. Hypertriglyceridemia-induced pancreatitis is a rare complication. We report 2 women who developed estrogen-associated severe hypertriglyceridemia with pancreatitis. The first patient developed pancreatitis secondary to hypertriglyceridemia associated with in vitro fertilization cycles. Marked reduction in her triglyceride was achieved with dietary restrictions and fibrate. The second patient developed pancreatitis secondary to hypertriglyceridemia during her pregnancies. She was noncompliant with the treatment; therefore, her triglyceride remained high after delivery. In both patients, no hypertriglyceridemia-associated genes mutations were identified, although the second patient had strong polygenic susceptibility to hypertriglyceridemia. Estrogen-induced severe hypertriglyceridemia with pancreatitis can be a life-threatening condition. Screening in high-risk patients is crucial to prevent subsequent complications.

    Proteomic technologies provide an excellent means for analysis of body fluids for cataloging protein constituents and identifying biomarkers for early detection of cancers. The biomarkers currently available for pancreatic cancer, such as CA19-9, lack adequate sensitivity and specificity...... contributing to late diagnosis of this deadly disease. In this study, we carried out a comprehensive characterization of the "pancreatic juice proteome" in patients with pancreatic adenocarcinoma. Pancreatic juice was first fractionated by 1-dimensional gel electrophoresis and subsequently analyzed by liquid...... in this study could be directly assessed for their potential as biomarkers for pancreatic cancer by quantitative proteomics methods or immunoassays....

    While conservative management such as fluid, bowel rest, and antibiotics is the mainstay of current acute pancreatitis management, there is a lot of promise in pharmacologic therapies that target various aspects of the pathogenesis of pancreatitis. Extensive review of preclinical studies, which include assessment of therapies such as anti-secretory agents, protease inhibitors, anti-inflammatory agents, and anti-oxidants are discussed. Many of these studies have shown therapeutic benefit and improved survival in experimental models. Based on available preclinical studies, we discuss potential novel targeted pharmacologic approaches that may offer promise in the treatment of acute pancreatitis. To date a variety of clinical studies have assessed the translational potential of animal model effective experimental therapies and have shown either failure or mixed results in human studies. Despite these discouraging clinical studies, there is a great clinical need and there exist several preclinical effective therapies that await investigation in patients. Better understanding of acute pancreatitis pathophysiology and lessons learned from past clinical studies are likely to offer a great foundation upon which to expand future therapies in acute pancreatitis.

    Relations between hyperlipidemia and chronic pancreatitis remain unclear. Microcirculatory disturbances and oxidative stress are involved in pathogeneses of a high numbers of diseases. The objective of this study was to induce hyperlipidemia in rats by long-term high-fat diet intake, then investigate the biochemical, microcirculatory, and histological alterations in blood and pancreatic tissues of these animals, and discuss their potential significances. Pancreatic blood flow was detected by intravital microscope; malondialdehyde (MDA) content and superoxide dismutase (SOD) activity were measured in pancreatic tissues for assessment of oxidative stress and α-smooth muscle actin (α-SMA) expression was determined by immunohistochemical staining and RT-PCR. The results showed that the velocity of pancreatic microvascular blood flow of rats with hyperlipidemia decreased significantly as compared to control value (p = 0.008). Pancreatic MDA content increased whereas SOD activity decreased in these rats (p = 0.022; p = 0.039, respectively). Histologically, microvesicles in acinar and islet cells, dilated rough endoplasmic reticulum, swollen mitochondrion and modified vascular endothelial cells were observed under light microscope and transmission electron microscope. In addition, α-SMA expression was up-regulated significantly (p < 0.05). These results suggest that long-term high-fat diet can induce chronic pancreatic injuries which could be considered as 'nonalcoholic fatty pancreatic disease', and pancreatic microcirculatory disturbances and oxidative stress may play an important part in the underlying pathogenesis

    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.)

Abdominal US and MRI showed a focal swelling of the pancreatic head, the latter also showing delayed contrast enhancement. There was diffuse irregular pancreatic duct narrowing, compression of the intrapancreatic common bile duct, and mild proximal biliary dilatation on MR cholangiopancreatography. Laboratory results revealed normal serum IgG and subclass 4 with negative autoimmune antibodies, and slightly elevated carbohydrate antigen 19-9. This highlights the differentiation of autoimmune pancreatitis from pancreatic head cancer and, to a lesser extent, other forms of pancreatitis in children. (orig.)

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

    2012-07-01

    As a primary energy producer, mitochondria play a fundamental role in pancreatic exocrine physiology and pathology. The most frequent aetiology of acute pancreatitis is either gallstones or heavy alcohol consumption. Repeated episodes of acute pancreatitis can result in the development of chronic pancreatitis and increase the lifetime risk of pancreatic cancer 100-fold. Pancreatic cancer is one of the most common causes of cancer mortality with only about 3-4 % of patients surviving beyond 5 years. It has been shown that acute pancreatitis involves Ca²⁺ overload and overproduction of reactive oxygen species in pancreatic acinar cells. Both factors significantly affect mitochondria and lead to cell death. The pathogenesis of inflammation in acute and chronic pancreatitis is tightly linked to the induction of necrosis and apoptosis. There is currently no specific therapy for pancreatitis, but recent findings of an endogenous protective mechanism against Ca²⁺ overload--and particularly the potential to boost this protection--bring hope of new therapeutic approaches.

    The incidence of acute pancreatitis (AP) is increasing and it is associated with a major healthcare concern. New insights in the pathophysiology, better imaging techniques, and novel treatment options for complicated AP prompted the update of the 1992 Atlanta Classification. Updated nomenclature for pancreatic collections based on imaging criteria is proposed. Adoption of the newly Revised Classification of Acute Pancreatitis 2012 by radiologists should help standardise reports and facilitate accurate conveyance of relevant findings to referring physicians involved in the care of patients with AP. This review will clarify the nomenclature of pancreatic collections in the setting of AP.

    Sun exposure has been associated with lower death rates for pancreatic cancer in ecological studies. Skin exposure to solar ultra-violet B radiation induces cutaneous production of precursors to 25-hydroxy (OH) vitamin D (D) and is considered the primary contributor to vitamin D status in most populations. Pancreatic islet and duct cells express 25-(OH) D3-1α-hydroxylase that generates the biologically active 1,25-dihydroxy(OH)2 D form. Thus, 25(OH)D concentrations could affect pancreatic fun...

    2015-09-01

    Biliary obstruction in chronic calcific pancreatitis (CCP) is often caused by inflammatory or fibrotic strictures of the bile duct, carcinoma of head of pancreas or less commonly by compression from pseudocysts. Pancreatic calculi causing ampullary obstruction and leading to obstructive jaundice is extremely rare. The medical records of all patients with CCP or biliary obstruction who underwent endoscopic retrograde cholangiopancreatography (ERCP) over 4 years between 2010-2014 at Kasturba Medical College, Manipal were analyzed. Five patients of CCP with impacted pancreatic calculi at the ampulla demonstrated during ERCP were identified. All 5 presented with biliary obstruction and were incidentally detected to have CCP when evaluated for the same; 3 patients had features of cholangitis. All the patients were managed successfully by endoscopic papillotomy and extraction of pancreatic calculi from the ampulla with resolution of biliary obstruction. Pancreatic calculus causing ampullary obstruction, though very rare, should be considered as a possibility in patients with CCP complicated by biliary obstruction. Endoscopic therapy is affective in the resolution of biliary obstruction in such patients.

    Full Text Available Tropical Calcific Pancreatitis (TCP is a type of chronic calcific nonalcoholic pancreatitis. Similar to nonalcoholic chronic pancreatitis, it presents in the second and third decades of life; however this type is reported mostly in the developing tropical and subtropical countries. It is associated with the formation of pancreatic calculi and a high probability of developing insulin-dependent diabetes mellitus. Epidemiologic studies have shown that these patients have an increased risk of developing pancreatic carcinoma. The etiology of TCP remains uncertain, with the current consensus suggesting genetics as well as possible toxicity from consuming large amounts of cassava, a tuber. Definite diagnosis of TCP requires younger age of onset, history of malnutrition, and presence of diabetes mellitus along with extensive pancreatic calcification and ductal calculi. When patients meet most but not all of these conditions the term Idiopathic Chronic Pancreatitis (ICP is used. This is a case of a 44-year-old man who presented with most features seen in TCP, and however, was diagnosed with ICP.

    The last two decades have seen the emergence of significant evidence that has altered certain aspects of the management of acute pancreatitis. While most cases of acute pancreatitis are mild, the challenge remains in managing the severe cases and the complications associated with acute pancreatitis. Gallstones are still the most common cause with epidemiological trends indicating a rising incidence. The surgical management of acute gallstone pancreatitis has evolved. In this article, we revisit and review the methods in diagnosing acute pancreatitis. We present the evidence for the supportive management of the condition, and then discuss the management of acute gallstone pancreatitis. Based on the evidence, our local institutional pathways, and clinical experience, we have produced an outline to guide clinicians in the management of acute gallstone pancreatitis. PMID:29563826

    Mucin-producing pancreatic cancers (MPPC), which include mucinous adenocarcinoma, papillary adenocarcinoma and cystadenocarcinoma, are radiographically characterized by diffuse or localized dilatation of the main pancreatic duct due to excessive mucin production. Therefore, MPPC are occasionally difficult to distinguish from chronic p
