Pancreatitis aguda en el escenario de hipercalcemia por hiperparatiroidismo primario / Acute pancreatitis in the setting of hypercalcemia due to primary hyperparathyroidism

Introducción: describir el caso de un paciente con pancreatitis aguda secundaria a hipercalcemia por hiperparatiroidismo prImario. Esta es una causa poco frecuente de pancreatitis, asociada a morbimortalidad significativa en caso de no ser diagnosticada oportunamente Caso clínico: un hombre de 44 años, con antecedente de pancreatitis de presunto origen biliar que había requerido previamente colecistectomía, consultó por dolor abdominal y náuseas. Los estudios complementarios fueron compatibles con un nuevo episodio de pancreatitis aguda. Presentaba hipercalcemia y hormona paratiroidea (PTH) elevada, configurando hiperparatiroidismo primario. La gammagrafía informó hallazgos compatibles con adenoma paratiroideo. Se inició tratamiento con reanimación hídrica y analgesia con adecuada disminución de calcio sérico y resolución de dolor abdominal. Después de la paratiroidectomía se logró normalizar los niveles de calcio y PTH. Discusión: la pancreatitis aguda es una condición potencialmente fatal, por lo que la sospecha de causas poco frecuentes como la hipercalcemia debe tenerse en cuenta. El tratamiento de la hipercalcemia por adenoma paratiroideo se basa en reanimación hídrica adecuada y manejo quirúrgico del adenoma, con el fin de evitar recurrencia de pancreatitis y mortalidad. (AU)

Introduction: we describe the case of a patient with acute pancreatitis secondary to hypercalcemia due to primary hyperparathyroidism. This is a rare cause of pancreatitis associated with significant morbidity and mortality if not diagnosed in time. Clinical case: a 44-year-old man with a history of pancreatitis of presumed biliary origin, which had previously required cholecystectomy, consulted for abdominal pain and nausea. The laboratory findings were compatible with a new episode of acute pancreatitis. He presented hypercalcemia and an elevated parathyroid hormone (PTH), configuring primary hyperparathyroidism. Scintigraphy was performed, yielding findings compatible with parathyroid adenoma. Treatment with fluid resuscitation and analgesia was started, resulting in an adequate decrease in serum calcium and resolution of abdominal pain. After parathyroidectomy, calcium and PTH levels were normalized. Discussion: acute pancreatitis is a potentially fatal condition; therefore the suspicion of rare causes, such as hypercalcemia, should be considered. The treatment of hypercalcemia due to parathyroid adenoma is based on adequate fluid resuscitation and surgical management of the adenoma, to avoid recurrence of pancreatitis and death. (AU)

Pancreatitis aguda por hipertrigliceridemia severa, caracterización en un hospital terciario / Acute pancreatitis due to severe hypertriglyceridemia, characterization in a tertiary hospital

La hipertrigliceridemia severa es una de las principales causas etiológicas de la pancreatitis aguda, donde la literatura internacional la posiciona como la tercera causa. Sus causas gatillantes, comorbilidades, severidad y evolución son importantes de conocer para evitar futuros episodios. En Chile, a nuestro entender, no tenemos literatura sobre esta asociación, por lo que presentamos datos de un hospital terciario, destacando 15 casos de pancreatitis aguda en 5 años de estudio, casi la mitad de ellos con antecedentes previos de hipertrigliceridemia, un porcentaje importante de los casos con cuadros graves y con complicaciones intrahospitalarias y que la diabetes mellitus tipo 2 fue la principal condición asociada a la hipertrigliceridemia severa.

Severe hypertriglyceridaemia is one of the main aetiological causes of acute pancreatitis, with international literature ranking it as the third leading cause. Its triggering causes, comorbidities, severity and evolution are important to know in order to avoid future episodes. In Chile, to our knowledge, we have no literature on this association, so we present data from a tertiary hospital, highlighting 15 cases of acute pancreatitis in 5 years of study, almost half of them with a previous history of hypertriglyceridaemia, a significant percentage of cases with severe symptoms and in-hospital complications, and that type 2 diabetes mellitus was the main condition associated with severe hypertriglyceridaemia.

Síndrome de quilomicronemia familiar: experiencia pediátrica en Argentina / Familial chylomicronemia syndrome: pediatric experience in Argentina

El síndrome de quilomicronemia familiar (SQF) es unaenfermedad autosómica recesiva rara, con una prevalencia1:200 000 - 1:1 000 000, y se caracteriza por quilomicronemiaen ayunas y niveles muy elevados de triglicéridos (> 880 mg/dl). LPL es el gen más frecuentemente afectado, luego APOC2,GPIHBP1, APOA5 y LMF1; todos ellos comprometen la función de la lipoproteinlipasa endotelial. El SQF suele presentarseen la infancia con dolor abdominal recurrente, xantomaseruptivos, retraso del crecimiento, pancreatitis y, en ocasiones,asintomático. El tratamiento convencional es la restriccióndietética de grasas. Se muestra el resultado clínico de 20 pacientes pediátricoscon SQF reclutados de 4 hospitales en Argentina.

Familial chylomicronemia syndrome (FCS) is a rare autosomalrecessive disease, prevalence 1:200,000 - 1:1,000,000, andis characterized by fasting chylomicrons and very hightriglycerides > 880 mg/dl. LPL is the most frequentlyaffected gene, then APOC2, GPIHBP1, APOA5, LMF1, all ofthem compromising the function of lipoproteinlipase. FCScommonly presents in childhood with recurrent abdominalpain, eruptive xanthomas, failure to thrive, pancreatitis, andsometimes asymptomatic. The conventional treatment isdietetic fat restriction. The clinical outcome of 20 pediatric patients with FCS recruited from 4 hospitals in Argentina is reported.

Crisis hipercalcémica, presentación inusual de adenoma paratiroideo: reporte de 2 casos / Hypercalcemic crisis, unusual presentation of parathyroid adenoma

La crisis hipercalcémica (CH) es una emergencia endocrina inusual, definida por la presencia de calcemia > 14 mg/dl asociada a disfunción renal, alteraciones cardiovasculares, gastrointestinales y del sensorio; también podría considerarse en pacientes con síntomas graves y calcemia menor. El hiperparatiroidismo primario (HPTP) y las neoplasias malignas son las etiologías más comunes de la hipercalcemia (90% de los casos); sin embargo, rara vez el primero se presenta como CH. Debido a la alta mortalidad asociada a esta entidad, es de gran importancia establecer diagnóstico y tratamiento precoces. Presentamos dos pacientes con crisis hipercalcémica como primera manifestación del HPTP, el 1.° con bloqueo auriculoventricular (AV) completo y el 2.° con pancreatitis aguda. La anatomía patológica (AP) reveló adenoma oxifílico en ambos casos, que es una variante histológica poco frecuente y puede manifestarse clínicamente de forma grave. Conclusiones: los adenomas paratiroideos son causa poco frecuente de CH. Consideramos el tipo histológico observado (adenoma oxifílico) como probable factor condicionante. La pancreatitis y especialmente el bloqueo AV son manifestaciones poco frecuentes de la CH. Resaltamos la importancia de la determinación de los niveles de calcio dentro de la evaluación inicial de todo paciente con bloqueo AV. (AU)

Hypercalcemic crisis (HC) is an unusual endocrine emergency, defined as the presence of serum calcium > 14 mg/dl related to kidney dysfunction, cardiovascular, gastrointestinal and sensory disturbances. It could also be considered in patients with severe symptoms and lower serum calcium levels. Primary hyperparathyroidism (PHPT) and malignant neoplasms are the most common hypercalcemia etiologies (90% of cases), nevertheless, the former hardly ever occurs as HC. Due to the high mortality associated with HC, it is crucial to establish early diagnosis and treatment.We report two patients with HC as the first manifestation of PHPT; the former with atrioventricular (AV) block and the latter with acute pancreatitis. Pathology revealed oxyphilic adenoma in both cases, which is an infrequent histological variant that can have a severe clinical manifestation. Conclusions: parathyroid adenomas are a rare cause of HC. We consider the histological type observed (oxyphilic adenoma) as a probable conditioning factor. Pancreatitis and especially AV block are rare manifestations of HC. We emphasize the importance of determining calcium levels in the initial evaluation of all patients with AV block. (AU)

Acute pancreatitis and COVID-19: a new target for infection?

ABSTRACT This review aimed to investigate whether SARS-CoV-2 is capable of infecting the gland and causing acute pancreatitis, and the peculiarities in the management of these cases. The research was conducted through PubMed® database, and 62 articles were systematically selected for analysis. Differences were found in the literature; however, there are important warnings, such as the presence of hyperlipasemia, clinical and imaging findings suggestive of acute pancreatitis in the presence and even in the absence of respiratory symptoms. Attention should be paid to clinical and imaging findings during this virus infection, since it is possible to identify these two diseases early. Therefore, it is possible to detect and isolate these patients more quickly, providing the correct care and decreasing the morbidity and mortality of two potentially severe diseases.

Profilaxia da pancreatite pós-colangiopancreatografia retrógrada endoscópica: avaliação de dois regimes com AINEs diferentes / Post endoscopic retrograde cholangiopancreatography pancreatitis prophylaxis: evaluation of two different nsaid regimens

ABSTRACT BACKGROUND: Endoscopic retrograde cholangiopancreatography is a widely used therapeutic modality for the pancreaticobiliary tree. However, it is responsible for the highest rates of complications among the endoscopic procedures, especially post-endoscopic retrograde cholangiopancreatography pancreatitis. The preventive methods include mechanical and pharmacological approaches, such as the use of non-steroidal anti-inflammatory drugs. OBJECTIVE: To compare the efficacy of two different strategies using non-steroidal anti-inflammatory drugs for the prevention of post-endoscopic retrograde cholangiopancreatography pancreatitis, and to clarify the uncertainty about the route of administration of non-steroidal anti-inflammatory drugs in the prevention of this complication. METHODS: This was a prospective trial. Two therapeutic groups were compared with a control group that was composed of patients who underwent endoscopic retrograde cholangiopancreatography, performed in the same service and by the same team in the period preceding the study (historical series), without the administration of any type of prophylaxis. The first group received 100 mg rectal diclofenac. The second group received 100 mg intravenous ketoprofen. Both groups were compared, separately and jointly, with the control group. RESULTS: Post-endoscopic retrograde cholangiopancreatography pancreatitis occurred in 4.39% (12/273) of the participants. In the group without prophylaxis, the incidence was 6.89% (10/145). Among those who received intravenous ketoprofen, the incidence was 2.56% (2/78). No cases of acute post-procedural pancreatitis were observed in the group that received rectal diclofenac (0/52). Although there was no statistical difference between the therapeutic groups when they were separately analyzed, a statistical difference in the prevention of post-procedural pancreatitis was observed when they were analyzed together (P=0.037). CONCLUSION: This study provides evidence for the efficacy of non-steroidal anti-inflammatory drugs in the prophylaxis of post-endoscopic retrograde cholangiopancreatography pancreatitis.

RESUMO CONTEXTO: A colangiopancreatografia retrógrada endoscópica (CPRE) é uma modalidade terapêutica amplamente utilizada para vias biliopancreáticas, responsável pelas taxas mais elevadas de complicações entre os procedimentos endoscópicos, especialmente a pancreatite pós-CPRE (PPC). Os métodos preventivos incluem abordagens mecânicas e farmacológicas, entre elas, a utilização de antinflamatórios não esteroidais (AINEs). OBJETIVO: Comparar a eficácia de duas estratégias diferentes utilizando AINEs para a prevenção de PPC. Elucidar o cenário incerto sobre a via de administração do AINEs na prevenção da PPC. MÉTODOS - Ensaio clínico prospectivo. Duas estratégias terapêuticas foram comparadas a um grupo controle, composto por pacientes submetidos a CPRE no mesmo serviço e com a mesma equipe no período anterior ao estudo (série histórica), que não recebeu qualquer tipo de profilaxia. O primeiro grupo experimental recebeu 100 mg de diclofenaco via retal, o segundo grupo recebeu 100 mg de cetoprofeno endovenoso. Ambos os grupos foram comparados separadamente e em associação com o grupo de controle. RESULTADOS: A PPC ocorreu em 4,39% (12/273) dos participantes. No grupo sem profilaxia, esta incidência foi de 6,89% (10/145); entre os que receberam cetoprofeno endovenoso foi de 2,56% (2/78). Não houve casos de pancreatite aguda após o procedimento no grupo que recebeu diclofenaco via retal (0/52). Apesar de não haver diferença estatística entre estes grupos analisados separadamente, quando os dois grupos terapêuticos são analisados em conjunto estes apresentam diferenças estatísticas na prevenção da PPC (P=0,037). CONCLUSÃO: Este estudo foi capaz de corroborar a eficácia da utilização de AINEs para a profilaxia de pancreatite pós-CPRE.

SARS-CoV-2 leading to acute pancreatitis: an unusual presentation

ABSTRACT During SARS-CoV-2 (severe acute respiratory syndrome coronavirus-2) pandemic, the etiologic agent of COVID-19, several studies described the involvement of other tissues besides the respiratory tract, such as the gastrointestinal tract. Angiotensin-converting enzyme-2, the functional virus host cell receptor expressed by organs and tissues, seems to have an important role in the pathophysiology and presentation of this disease. In pancreas, this receptor is expressed in both exocrine glands and islets, being a potential target for the virus and subsequent pancreatic injury. There are few articles reporting pancreatic injury in COVID-19 patients but most of them do not report acute pancreatitis. Diagnosing acute pancreatitis secondary to SARS-CoV-2 infection is challenging due to the need to rule out other etiologies as well the notable heterogeneous presentations. Herein we report the case of a patient with COVID-19 who developed severe acute pancreatitis.

Ansa pancreática: desafio no diagnóstico etiológico em paciente jovem com pancreatite grave / Ansa pancreatica: etiological diagnosis challenge in a young patient with severe pancreatitis

A ansa pancreática é uma variação anatômica rara dos ductos pancreáticos. Consiste numa comunicação entre o ducto pancreático principal (Wirsung) e o ducto pancreático acessório (Santorini). Recentemente, estudos têm demonstrado estar essa variação anatômica implicada como fator predisponente e significativamente associada a episódios recorrentes de pancreatite aguda. A pancreatite é uma entidade clínica pouco frequente na infância. Diferente dos adultos, as causas mais comuns incluem infecções virais, por ascaris, medicamentosas, traumas e anomalias estruturais. O objetivo deste estudo foi relatar um caso de pancreatite aguda grave não alcoólica e não biliar, em um paciente jovem de 15 anos, em cuja propedêutica imagenológica evidenciou-se alça, comunicando com os ductos pancreáticos ventral e dorsal, compatível com ansa pancreática.

Ansa pancreatica is a rare anatomical variation of the pancreatic ducts. It consists of communication between the main pancreatic duct (Wirsung) and the accessory pancreatic duct (Santorini). Recently, studies have shown that this anatomical variation is implicated as a predisposing factor and significantly associated with recurrent episodes of acute pancreatitis. Pancreatitis is a rare clinical entity in childhood. Different from that in the adults, the most common causes include viral and ascaris infections, drugs, traumas, and structural abnormalities. The objective of this study was to report a case of a severe non-alcoholic and non-biliary acute pancreatitis in a 15-year-old patient, whose propedeutic imaging showed a loop communicating with the ventral and dorsal pancreatic ducts, consistent with ansa pancreatica.

Efecto del manejo farmacológico del sistema nervioso autónomo en la pancreatitis aguda inducida por el veneno de escorpión Tityus zulianus en un modelo ex vivo / Effect of the pharmacological management of the autonomic nervous system in the acute pancreatitis induced by the venom of Tityus zulianus scorpion in an ex vivo model

La pancreatitis es una de las consecuencias principales del envenenamiento escorpiónico producido por el género Tityus. El manejo farmacológico mediante el uso de agonistas y antagonistas α adrenérgicos en modelos experimentales in vivo e in vitro, permiten establecer una aproximación del papel del Sistema Nervioso Simpático (SNS) en el desarrollo de la pancreatitis. Objetivo: determinar el papel del SNS en el desarrollo de la pancreatitis aguda inducida por el veneno de escorpión Tityus zulianus (TzV), por medio del uso de simpaticolíticos como la clonidina y el prazosin. Métodos: La Extravasación de Proteínas Plasmáticas (EPP) en el páncreas se evaluó mediante el método de Azul de Evans (AE), modificado de Saria y Lundberg (1983) a 620 nm; n=3 ratones NIH en cada grupo experimental. Las comparaciones se hicieron por ANOVA de una vía y las pruebas post HOC por Tukey-Kramer. Resultados: Ambos fármacos (1mg/Kg), disminuyeron significativamente p< 0,01 (**) la EPP en el páncreas inducida por el TzV, en comparación con los animales inoculados solo con TzV. No hubo diferencias significativas entre los animales del grupo control y los grupos tratados con los fármacos más el TzV. Conclusiones: El efecto pancreatotóxico del TzV en ratones podría tener un componente autonómico dado que drogas simpaticolíticas al disminuir la actividad noradrenérgica reducen la magnitud del edema. Esto sugiere que ambos fármacos pueden usarse como estrategia terapéutica en estos casos(AU)

Pancreatitis is one of the main consequences of scorpionic poisoning produced by the genus Tityus. The pharmacological management through the use of agonists and α adrenergic antagonists in experimental models in vivo and in vitro, allow us to establish an approximation of the role of the Sympathetic Nervous System (SNS) in the development of pancreatitis. Objective: to determine the role of SNS in the development of acute pancreatitis induced by the scorpion venom Tityus zulianus (TzV), through the use of sympatholytics such as clonidine and prazosin. Methods: Plasma Protein Extravasation (PPE) in the pancreas was evaluated by the method of Evans Blue (EA), modified by Saria and Lundberg (1983) at 620 nm; n = 3 NIH mice in each experimental group. Comparisons were made by one-way ANOVA and post-HOC tests by Tukey-Kramer. Results: Both drugs (1mg / Kg) significantly decreased p <0.01 (**) the EPP in the pancreas induced by TzV, compared to animals inoculated only with TzV. There were no significant differences between the animals in the control group and the groups treated with drugs plus TzV. Conclusions: The pancreatotoxic effect of TzV in mice could have an autonomic component since sympatholytic drugs by decreasing noradrenergic activity reduce the magnitude of edema. This suggests that both drugs can be used as a therapeutic strategy in these cases(AU)

Pancreatitis aguda en carcinoma de célula pequeña de pulmón (CPCP) resuelta con quimioterapia / Acute pancreatitis in small-cell lung carcinoma (SCLC) resolved with chemotherapy

Resumen El carcinoma de célula pequeña (CPCP) o microcítico de pulmón es un subtipo de cáncer de pulmón que típicamente se ha asociado al tabaquismo y que se caracteriza por su agresividad y mal pronóstico a corto plazo. Como entidad, puede metastatizar en cualquier órgano, siendo las metástasis pancreáticas raras y la mayoría de las veces asintomáticas. Por ello, la presencia de una pancreatitis neoplásica, como en el caso presentado, es excepcional, y aún más cuando presenta refractariedad al tratamiento médico convencional y responde al tratamiento citotóxico sistémico. Por todo ello, se expone esta experiencia clínica y se debate la presencia de esta rara entidad y su manejo.

Abstract Small-cell lung carcinoma is a subtype of neoplasm that has been typically associated with smoking; it is characterized by its aggressiveness and poor prognosis in the short term. As an entity, it can metastasize in any organ, but pancreatic metastases are rare and most of the time asymptomatic. Therefore, the presence of neoplastic pancreatitis as in our case is exceptional; even more when it presents refractoriness to conventional medical treatment, responding instead to systemic cytotoxic treatment. Therefore, we expose our clinical experience and discuss the presence of this rare entity and its management.

Acute pancreatitis and recurrent acute pancreatitis: an exploration of clinical and etiologic factors and outcomes / Pancreatite aguda e pancreatite aguda recorrente: uma exploração de fatores clínicos e etiológicos e desfechos

ABSTRACT Objective: To describe the epidemiology and clinical features of acute pancreatitis and recurrent acute pancreatitis in children. Methods: Observational and retrospective study with an analytical component. Patients were classified into two groups: Acute pancreatitis and recurrent pancreatitis. The relationship with each parameter obtained was analyzed using the chi-squared test, Student's t-test, or the Mann-Whitney U test. Results: There were 130 patients with acute pancreatitis; recurrent pancreatitis was diagnosed in 23.8% of the cases. The most frequent causes were anatomical (29.6%), pharmacological (19.2%), and biliary (14.6%), although in 29.2% etiology was not identified. Fasting lasted 3.5 ± 3.8 days and parenteral nutrition was indicated in 26.9% of the cases for 10.8 ± 11.3 days. A statistical association with anatomical (p = 0.02) and pharmacological causes (p = 0.01) was found in the recurrent pancreatitis group; no other differences between acute pancreatitis and recurrent pancreatitis groups were observed. The mortality rate was 3.1%, it was not attributable to acute pancreatitis in any cases. Conclusion: Acute pancreatitis is associated with a high frequency of acute recurrent pancreatitis. Severity and complications did not show statistically significant differences in this investigation. Anatomical etiologies were the most relevant cause in this cohort. Fasting time and parenteral nutrition use were relevant. Genetics testing is required in this population.

RESUMO Objetivo: Descrever a epidemiologia e as características clínicas da pancreatite aguda e da pancreatite aguda recorrente em crianças. Métodos: Estudo observacional e retrospectivo com um componente analítico. Os pacientes foram classificados em dois grupos: pancreatite aguda e pancreatite recorrente. A relação com cada parâmetro obtido foi analisada com o teste de qui-quadrado, teste t de Student ou teste U de Mann-Whitney. Resultados: Foram analisados 130 pacientes com pancreatite aguda; pancreatite recorrente foi diagnosticada em 23,8% dos casos. As causas mais frequentes foram anatômicas (29,6%), farmacológicas (19,2%) e biliares (14,6%), embora em 29,2% a etiologia não tenha sido identificada. O jejum durou 3,5 ± 3,8 dias e a nutrição parenteral foi indicada em 26,9% dos casos por 10,8 ± 11,3 dias. Uma associação estatística com causas anatômicas (p = 0,02) e farmacológicas (p = 0,01) foi encontrada no grupo com pancreatite recorrente; não foram observadas outras diferenças entre os grupos pancreatite aguda e pancreatite recorrente. A taxa de mortalidade foi de 3,1% e nenhum caso foi atribuível à pancreatite aguda. Conclusão: A pancreatite aguda está associada à alta frequência de pancreatite aguda recorrente. A gravidade e as complicações não apresentaram diferenças estatísticas nesta investigação. Etiologias anatômicas foram a causa mais relevante nesta coorte. O tempo de jejum e o uso de nutrição parenteral foram relevantes. Testes genéticos são necessários em nossas populações.

Canulación biliar difícil: precorte precoz tipo fistulotomía para evitar la pancreatitis post CPRE. Un análisis retrospectivo de dos años / Difficult biliary cannulation: early precut fistulotomy to avoid post ERCP pancreatitis. A retrospective analysis for two years

Antecedentes: La canulación biliar difícil es un factor de riesgo para la pancreatitis post-CPRE. En estos casos el precorte es la técnica más usada. Objetivo: Demostrar que el precorte tipo fistulotomía es seguro y eficaz. Materiales y métodos: Se revisaron los datos de mayo de 2016 a mayo de 2018. Se definió canulación difícil como: litiasis impactada, canulación inadvertida del conducto pancreático en tres ocasiones e incapacidad para lograr la canulación en 3 minutos. Las medidas de resultados fueron la canulación biliar exitosa y la pancreatitis post-CPRE. Resultados: Se realizó precorte tipo fistulotomía en 96 casos (67 mujeres, 29 hombres). La tasa de éxito de la canulación biliar fue del 95,8% (92/96). Ochenta pacientes tenían factores de riesgo para pancreatitis post CPRE: 29 tuvieron un solo factor de riesgo, 26 tuvieron dos, 19 tuvieron tres y 6 tuvieron cuatro. Factores de riesgo ampulares de canulación difícil: calculo impactado 9 casos, abultamiento de la papila en 10 casos, ubicación inferior del orificio papilar en 38 casos, localización parcial del poro papilar en 23 y estenosis del orificio papilar en 16 casos. Diez pacientes tuvieron divertículo periampular, 7 pacientes tuvieron conducto biliar normal. Ninguno de los pacientes experimentó pancreatitis. Tres pacientes tuvieron sangrado precoz, una paciente presento sangrado tardío. Un paciente (2%) tuvo fiebre y fue hospitalizado. Conclusiones: En casos de canulación biliar difícil el precorte tipo fistulotomía es seguro y eficaz.

Background: Difficult biliary cannulation is a risk factor for post-ERCP pancreatitis. In these cases, precutting is the most used technique. Objective: To demonstrate that precut fistulotomy is safe and effective. Materials and methods: Data from May 2016 to May 2018 were reviewed. Difficult cannulation was defined as: impacted lithiasis, inadvertent cannulation of the pancreatic duct on three occasions and inability to achieve deep biliary cannulation in 3 minutes. The outcome measures were successful biliary cannulation and post-ERCP Pancreatitis. Results: Precut fistulotomy was performed in 96 cases (67 women, 29 men). The success rate of biliary cannulation was 95.8% (92/96). Eighty patients had risk factors for post-ERCP pancreatitis: 29 had 1 risk factor, 26 had 2 risk factors, 19 had 3 risk factors, and 6 had four risk factors. Ampullary risk factors of difficult cannulation: impacted stone in the papilla: 9 cases, papilla bulging: 10 cases, lower location of the hole papillary 38 cases, partial location of the papillary pore 23 and papillary orifice stenosis 16 cases. Ten patients had periampullary diverticulum, 7 patients had normal bile duct. None of the patients experienced Pancreatitis. Three patients had early bleeding, one patient had late bleeding. One patient (2%) had a fever and was hospitalized. Conclusions: In cases of difficult biliary cannulation, the precut fistulotomy is safe and effective.

Pancreatitis aguda por hipercalcemia en el embarazo: caso clínico / Acute pancreatitis due to hypercalcemia during pregnancy: report of one case

Acute pancreatitis during pregnancy is uncommon and usually associated with gallstones. However other etiologies must be considered. We report a 24 years old woman with a 32 weeks pregnancy consulting for abdominal pain, nausea and vomiting. She had elevated lipase and amylase levels, a corrected serum calcium of 13.1 mg/dl and a serum phosphate of 1.6 mg/dl. A magnetic resonance colangiopancreatography showed an enlarged pancreas with inflammatory changes and a normal Wirsung duct. A parathyroid nodule was found on cervical ultrasonography. The patient was treated initially with cinacalcet with partial response. A parathyroidectomy was performed at 39 weeks of pregnancy with a good maternal and fetal evolution.

CA 19-9 levels in patients with acute pancreatitis due to gallstone and metabolic/toxic reasons

SUMMARY OBJECTIVE Acute pancreatitis (AP) is an important clinical event with an increased frequency due to increased life expectancy, obesity, and alcohol use. There are some data about the elevation of carbohydrate antigen (CA) 19-9 levels in benign and malignant pancreaticobiliary events in the literature, but in AP they are limited. The aim of this study was to evaluate the CA 19-9 level in patients with AP and determine its relationship according to the cause. METHODS Between 2010-2018, 173 patients evaluated with CA 19-9 levels as well as by standard laboratory tests were included in the study. CA 1 9-9 levels and laboratory findings were compared in patients with pancreatitis due to gallstone (group 1) and metabolic/toxic reasons such as hyperlipidemia, alcohol, or drug use (group 2). RESULTS There were 114 (66%) patients in the group 1 and 59 (34%) patients in the group 2. The majority of patients with high CA 19-9 level were in group 1 (92.1% vs 6.8%). CA 19-9 level, as well as amylase, lipase, AST, ALT and bilirubin levels were found to be statistically higher in patients with AP due to gallstone compared to patients with metabolic/toxic AP. CONCLUSIONS Patients with AP due to gallstone, were found to have a high level of CA 19-9 at admission. Early stage CA 19-9 levels may contribute to standard laboratory tests in the etiology of the disease in patients diagnosed with AP.

RESUMO OBJETIVO A pancreatite aguda (PA) é um evento clínico importante e cada vez mais frequente devido ao aumento da expectativa de vida, obesidade e do consumo de álcool. Existem alguns dados na literatura sobre a elevação dos níveis do antígeno carboidrato (CA) 19-9 em eventos pancreato-biliares benignos e malignos, mas eles são limitados em relação à PA. O objetivo deste estudo foi avaliar o nível de CA 19-9 em pacientes com PA e determinar sua relação com a causa da doença. PACIENTES E MÉTODOS Entre 2010 e 2018, 173 pacientes submetidos a uma avaliação dos níveis de CA 19-9, bem como testes laboratoriais padrão, foram incluídos no estudo. Os níveis de CA 19-9 e os achados laboratoriais foram comparados em pacientes com pancreatite devido a cálculos biliares (grupo 1) e razões metabólicas/tóxicas, como hiperlipidemia, álcool, ou uso de drogas (grupo 2). RESULTADOS Um total de 114 (66%) pacientes foi incluído no grupo 1 e 59 (34%) no grupo 2. A maioria dos pacientes com alto nível de CA 19-9 estavam no grupo 1 (92,1% versus 6,8%). O CA 19-9, bem como os níveis de amilase, lipase, AST, ALT e bilirrubina foram estatisticamente mais altos em pacientes com PA devido a cálculos biliares em comparação àqueles com PA devido a alterações metabólicas/tóxicas. CONCLUSÃO Pacientes com PA devido a cálculos biliares apresentaram um alto nível de CA 19-9 no momento da internação. O nível de CA 19-9 na fase inicial pode contribuir para testes laboratoriais padrão na etiologia da doença em pacientes com diagnóstico de PA.

Análisis de los factores pronósticos en pacientes con pancreatitis aguda / Analysis of prognostic factors in patients with acute pancreatitis

RESUMEN Introducción: la pancreatitis aguda es una enfermedad muy frecuente que se define como un proceso inflamatorio reversible del tejido pancreático, producido por la activación intraparenquimatosa de enzimas digestivas. Objetivo: determinar los factores pronósticos tempranos en la pancreatitis aguda, de causa biliar y no biliar, asociados a evolución desfavorable. Métodos: se realizó un estudio observacional analítico en pacientes con pancreatitis aguda, atendidos en el Hospital Universitario Clínico-Quirúrgico «Arnaldo Milián Castro¼ (2013 - 2017). Se empleó un muestreo no probabilístico intencional, por criterios de inclusión y exclusión. Resultados: la edad media de los pacientes egresados y con pancreatitis aguda no biliar, fue significativamente menor que la de los fallecidos. Se identificaron como factores de riesgo en la ocurrencia de mortalidad: la edad mayor de 65 años (OR=3,813-IC: 1,451-10,025), el sexo femenino (OR=2,700-IC: 1,044-6,981), la pancreatitis de origen biliar (OR=1,279-IC: 0,321-5,102), la pancreatitis aguda necrótica (OR=7,822-IC: 1,772-34,526), la presencia de derrame pleural (OR=5,929-IC: 1,912-18,386) y un índice de gravedad tomográfica (IGT)> D (OR=2,800-IC: 0,381-20,579). Los resultados de los valores de sensibilidad, especificidad, valor predictivo positivo y negativo de la TGO, y la TGP, en relación a la pancreatitis aguda necrótica hemorrágica, fueron de (37,5 %, 69,7 %, 23,1 % y 82,1%) y (60 %, 83,3 %, 42,9 % y 90,9 %), respectivamente. El área bajo la curva de la TGP fue de 0,790. Conclusiones: se identificaron como factores negativos: la edad mayor de 65, el origen biliar, la pancreatitis aguda necrótica, el derrame pleural y la gravedad tomográfica.

ABSTRACT Introduction: acute pancreatitis is a very common disease that is defined as a reversible inflammatory process of pancreatic tissue, produced by the intraparenchymal activation of digestive enzymes. Objective: to determine the early prognostic factors in acute biliary and non-biliary pancreatitis associated with an unfavorable evolution. Methods: an analytical observational study was performed in patients with acute pancreatitis seen at "Arnaldo Milián Castro" Clinico-Surgical University Hospital from 2013 to 2017. Intentional non-probabilistic sampling was used following inclusion and exclusion criteria. Results: the average age of the discharged patients and patients with acute non-biliary pancreatitis was significantly lower than the average age of the deceased ones. We identified as risk factors in the occurrence of mortality: age over 65 years (OR = 3.813-CI: 1.451-10.025), female gender (OR = 2.700-CI: 1.044-6.981), biliary pancreatitis (OR = 1.279-CI: 0.321-5.102), acute necrotizing pancreatitis (OR = 7.822-CI: 1.772-34.526), the presence of pleural effusion (OR = 5.929-CI: 1.912-18.386) and a computed tomographic severity index (CTSI)> D (OR = 2.800-CI: 0.381-20.579). The results of the values of sensitivity, specificity, positive and negative predictive value of AST and ALT, in relation to acute necrotizing hemorrhagic pancreatitis, were (37.5%, 69.7%, 23.1% and 82.1%) and (60%, 83.3%, 42.9% and 90.9%), respectively. The area under the curve for ALT was 0.790. Conclusions: we identified as negative factors: age over 65, biliary origin, acute necrotizing pancreatitis, pleural effusion and tomographic severity.

A rare case of recurrent acute pancreatitis after EUS-FNA in a patient with pancreatic intraepithelial neoplasia type 2 / Un raro caso de pancreatitis aguda recurrente después de EUS-FNA en un paciente con neoplasia intraepitelial tipo 2

Pancreatic intraepithelial neoplasia (PanIN) is considered a pre-malignant lesion difficult to identify by imaging methods. EUS- FNA is an effective technique to obtain material for histopathological study of pancreatic cystic tumors, but it is not free of adverse events. We report a case of a 56 years old patient, with chronic abdominal pain (early 1994). MRI showed pancreatic cystic images. The etiologic diagnosis was doubtful and EUS-FNA was performed. Immediately after a FNA, patient had an episode of acute pancreatitis, requiring hospitalization. During one year after FNA he had five episodes of AP. A new EUS suspected of PanIN, which was confirmed by surgery. After surgery the patient is well and has no more episodes of AP. Although the risk of AP, EUS-FNA should be performed to determine the best treatment for these patients with chronic abdominal pain who have cystic changes of pancreatic gland.

La neoplasia intraepithelial pancreática (PanIN) es considerada una lesión premaligna con dificultad diagnostica mediante métodos imagenlógicos. La EUS-FNA es una técnica efectiva para obtener material para el estudio histopatológico de tumores quísticos pancreáticos, pero no está libre de efectos adversos. Nosotros reportamos un caso de un paciente de 56 años de edad, con dolor abdominal cronico (desde 1994). En la resonancia abdominal se observó un quiste pancreático. El diagnostico etiológico fue dudoso y EUS-FNA fue realizada, después de la cual el paciente presento un cuadro de pancreatitis, requiriendo hospitalización. Durante el periodo de un año posterior a la FNA, éste presento cinco episodios de pancreatitis aguda. Un nuevo estudio ecoendoscopico dio la sospecha de PanIN, la cual se confirmó con la realización de la cirugía. Después de la cirugía quedo asintomático y sin presentar nuevos episodios de pancreatitis aguda hasta el momento. Aunque exista riego de pancreatitis aguda, la EUS-FNA debe realizarse para determinar el mejor tratamiento para pacientes con dolor abdominal crónico que tienen cambios quísticos de la glándula pancreática.

Análisis de los factores pronósticos en pacientes con pancreatitis aguda / Analysis of prognostic factors in patients with acute pancreatitis

Introducción: la pancreatitis aguda es una enfermedad muy frecuente que se define como un proceso inflamatorio reversible del tejido pancreático, producido por la activación intraparenquimatosa de enzimas digestivas. Objetivo: determinar los factores pronósticos tempranos en la pancreatitis aguda, de causa biliar y no biliar, asociados a evolución desfavorable. Métodos: se realizó un estudio observacional analítico en pacientes con pancreatitis aguda, atendidos en el Hospital Universitario Clínico-Quirúrgico «Arnaldo Milián Castro¼ (2013 2017). Se empleó un muestreo no probabilístico intencional, por criterios de inclusión y exclusión. Resultados: la edad media de los pacientes egresados y con pancreatitis aguda no biliar, fue significativamente menor que la de los fallecidos. Se identificaron como factores de riesgo en la ocurrencia de mortalidad: la edad mayor de 65 años (OR=3,813-IC: 1,451-10,025), el sexo femenino (OR=2,700-IC: 1,044-6,981), la pancreatitis de origen biliar (OR=1,279-IC: 0,321-5,102), la pancreatitis aguda necrótica (OR=7,822-IC: 1,772-34,526), la presencia de derrame pleural (OR=5,929-IC: 1,912-18,386) y un índice de gravedad tomográfica (IGT)> D (OR=2,800-IC: 0,381-20,579). Los resultados de los valores de sensibilidad, especificidad, valor predictivo positivo y negativo de la TGO, y la TGP, en relación a la pancreatitis aguda necrótica hemorrágica, fueron de (37,5 %, 69,7 %, 23,1 % y 82,1%) y (60 %, 83,3 %, 42,9 % y 90,9 %), respectivamente. El área bajo la curva de la TGP fue de 0,790. Conclusiones: se identificaron como factores negativos: la edad mayor de 65, el origen biliar, la pancreatitis aguda necrótica, el derrame pleural y la gravedad tomográfica.

Endovascular treatment of acute gastrointestinal bleeding from a large splenic artery pseudoaneurysm: case report and literature review / Tratamento endovascular da hemorragia digestiva aguda por volumoso pseudoaneurisma esplênico: relato de caso e revisão da literatura

O pseudoaneurisma da artéria esplênica é uma entidade rara, com pouco mais de 150 casos descritos na literatura. A pancreatite é a etiologia mais comum, seguida do trauma. Em contraposição ao aneurisma verdadeiro, esse pseudoaneurisma é frequentemente sintomático, com risco de ruptura de 47% e mortalidade de 90%, quando não tratado. Descrevemos o caso de uma paciente de 48 anos que apresentou hemorragia gastrointestinal associada a pancreatite crônica agudizada. Durante investigação, a endoscopia evidenciou sinais de sangramento recente, e a angiorressonância de abdome observou volumoso pseudoaneurisma da artéria esplênica. Foi submetida a tratamento endovascular com embolização com micromolas, não apresentando novos episódios de sangramento. Atualmente, o tratamento endovascular é efetivo com baixa morbimortalidade e taxas de sucesso de 79-100%, sendo uma técnica viável para pacientes com processo inflamatório abdominal em franca atividade. Realizamos uma revisão das técnicas endovasculares e agentes embolizantes usados para o tratamento dessa patologia

Pseudoaneurysm of the splenic artery is a rare entity, with little more than 150 cases described in the literature. Pancreatitis is the most common etiology, followed by trauma. In contrast with true aneurysms, pseudoaneurysms are frequently symptomatic, with a 47% risk of rupture and 90% mortality if left untreated. We describe the case of a 48-year-old female patient who suffered a gastrointestinal hemorrhage associated with acute-on-chronic pancreatitis. During workup, endoscopy revealed signs of recent bleeding and magnetic resonance angiography of the abdomen showed a large pseudoaneurysm of the splenic artery. The patient underwent endovascular treatment with microcoil embolization and no further bleeding episodes occurred. Endovascular treatment is now an effective option with low morbidity and mortality and success rates in the range of 79-100%, making it a viable technique for patients with active abdominal inflammation. We conducted a review of endovascular techniques and embolization agents used to treat this pathology

Pancreatitis aguda secundaria a un trauma abdominal: reporte de caso de una niña de 7 años / Acute pancreatitis secondary to an abdominal trauma: case report of a 7-year-old child

La pancreatitis consiste en la inflamación aguda del páncreas, que se caracteriza, clínicamente, por dolor abdominal. Para realizar el diagnóstico, es necesario que se presente la elevación de marcadores bioquímicos, como amilasa o lipasa pancreáticas. Esta afección es la enfermedad pancreática más frecuente tanto en niños como en adultos. Su presentación en la población pediátrica está en aumento y tiene varias etiologías, como infecciones, trauma, intoxicación y enfermedades metabólicas. Entre los mecanismos de trauma, se han descrito maltrato infantil, caídas, trauma con el manubrio de la bicicleta y accidentes de tránsito. En este artículo, se presenta un caso de pancreatitis secundaria a un trauma abdominal con el manubrio de una bicicleta en una paciente de 7 años.

Pancreatitis consists in acute inflammation of the pancreas that is clinically characterized by abdominal pain. To make the diagnosis it is necessary the elevation of biochemical markers like pancreatic amylase or lipase. It is the most frequent pancreatic disease in both children and adults. Its presentation in the pediatric population is increasing and has several etiologies such as: infections, trauma, intoxication and metabolic diseases. Trauma mechanisms have been described: child maltreatment, falls, trauma with the bicycle handle and traffic accidents. In this article, we present a case of pancreatitis secondary to an abdominal trauma with the handle of a bicycle in a patient of 7 years.
