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.

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)

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.

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.

Guide wire-assisted cannulation versus conventional contrast to prevent pancreatitis: A systematic review and meta-analysis based on randomized control trials / Canulación asistida por alambre guía versus contraste convencional para prevenir la pancreatitis: Una revisión sistemática y meta-análisis basados en ensayos aleatorios controlados

Objective: Through this systematic review and meta-analysis, we aim to clarify the differences between these two techniques, thus improving primary success cannulation and reducing complications during endoscopic retrograde cholangiopancreatography, primarily pancreatitis. Methods: A comprehensive search was conducted to search for data available up until June2015from the most important databases available in the health field: EMBASE, MEDLINE (via PubMed), Cochrane, LILACS and CENTRAL (via BVS), SCOPUS, the CAPES database (Brazil), and gray literature. Results: Nine randomized clinical trialsincluding2583 people were selected from20,198 studies for meta-analysis. Choledocholithiasis had been diagnosed in mostly (63.8%) of the patients, who were aged an average of 63.15 years. In those patients treated using the guide wire-assisted cannulation technique, provided a significantly lower instance of pancreatitis (RD=0.03; 95% CI: 0.01-0.05; I2= 45%) and greater primary success cannulation (RD=0.07; 95% CI: 0.03-0.12; I2=12%) than conventional contrast cannulation. Conclusions: The guide wire-assisted technique, when compared to the conventional contrast technique, reduces the risk of pancreatitis and increases primary success cannulation rate. Thus, guide wire-assisted cannulation appears to be the most appropriate first-line cannulation technique

Objetivo: A través de esta revisión sistemática y meta-análisis, nuestro objetivo es aclarar las diferencias entre estas dos técnicas, mejorando así la canulación de éxito primario y reducir las complicaciones durante la colangiopancreatografía retrógrada endoscópica, principalmente la pancreatitis. Métodos: Una búsqueda exhaustiva se realizó para buscar datos disponibles hasta junio de 2015, desde las bases de datos más importantes disponibles en el campo de la salud: EMBASE, MEDLINE (vía PubMed), Cochrane, LILACS y CENTRAL (a través de la BVS), SCOPUS, la base de datos CAPES (Brasil), y la literatura gris. Resultados: Nueve ensayos clínicos aleatorios incluyendo 2583 personas fueron seleccionados de 20198 estudios de meta- análisis. Coledocolitiasis había sido diagnosticada en su mayoría (63,8%) de los pacientes, que tenían entre un promedio de 63,15 años. En los pacientes tratados con la técnica de canulación guiada, proporcionado una instancia significativamente menor de pancreatitis (RD=0,03; IC del 95%: 0,01-0,05; I2=45%) y una mayor canalización de éxito primario (RD=0,07; IC del 95%: 0,03-0.12; I2=12%) que la canulación por contraste. Conclusiones: La técnica canulación con alambre guía, en comparación a la técnica de contraste convencional, reduce el riesgo de pancreatitis y aumenta la tasa de canulación con éxito primario. Por lo tanto, canulación con alambre guía parece ser la técnica de canulación de primera línea y la más adecuada

Prophylactic Pancreatic Stent Placement for Endoscopic Duodenal Ampullectomy: A Single-Center Retrospective Study

BACKGROUND/AIMS: We investigated the efficacy of prophylactic pancreatic stent placement for preventing postprocedure pancreatitis in patients undergoing endoscopic papillectomy. METHODS: This retrospective study included 82 consecutive patients who underwent endoscopic papillectomy for benign ampullary neoplasm at Samsung Medical Center between August 2002 and June 2011. The patients were subdivided into two groups, namely, those who received prophylactic pancreatic stent placement and those who did not. Patient demographics, baseline blood test, tumor characteristics, and endoscopic treatment data were collected. The primary endpoint was postprocedure pancreatitis. RESULTS: There was no difference in the development of postprocedure pancreatitis between the stent group and the no stent group (6/54, 10.5% and 2/28, 7.14%, respectively; p=1.00). At baseline, there were no significant differences between the two groups in terms of their risk factors for pancreatitis except pancreatic duct dye injection. The stent group was more likely to have dye injection than the nonstent group (100% vs 42.8%, p<0.001). However, in a logistic regression analysis, no significant difference was observed in the risk factors for pancreatitis including dye injection. CONCLUSIONS: Our data suggest that routine prophylactic pancreatic duct stent placement in all patients undergoing endoscopic papillectomy may not be necessary and that large-scale prospective studies are required to identify the subgroup of patients who would benefit.

Preventive effect of cichorium intybus l. two extracts on cerulein-induced acute pancreatitis in mice

Acute pancreatitis is an inflammatory condition of pancreas with sudden onset, high mortality rate and multiple organ failure characteristics. It has been shown that oxygen free radicals have an important role in development of pancreatitis and its complications. Antioxidant, anti-inflammatory, anti-hepatotoxicity and gastroprotective properties of Cichorium intybus L. suggest that this plant may have beneficial effects in the management of acute pancreatitis. Five intraperitoneal [i.p.] injection of cerulean [50 microg/ kg at 1 h intervals] in mice resulted in acute pancreatitis, which was characterized by edema, neutrophil infiltration, as well as increases in the serum levels of amylase and lipase in comparison to normal mice. Different doses of C. intybus root [CRE] and aerial parts hydroalcoholic extract [CAPE] orally [50, 100, 200 mg/kg] and intraperitoneally [50, 100, 200 mg/kg] were administrated 1.0 and 0.5 h respectively before pancreatitis induction on separate groups of male mice [n=6]. Control groups treated with normal saline [5 ml/ kg] similarly. Both extracts in greater test doses [100 mg/kg and 200 m/kg, i.p.] were effective to decrease amylase [23-36%] and lipase [27-35%] levels. In oral route, the dose of 200 mg/ kg showed a significant decrease in levels of amylase [16%] and lipase [24%] activity while the greatest dose [200 mg/kg, i.p.] was only effective to diminish inflammatory features like edema and leukocyte infiltration in pancreatitis tissue [P<0.01]. Vacuolization was not significantly reduced in extracts treated groups. These data suggest that C. intybus hydroalcoholic extracts were effective to protect against experimental acute pancreatitis and the efficacy was partly dependent to the dose and was more significant after parenteral administration

Pancreatitis post colangiopancreatografía retrógrada endoscópica ¿Es posible prevenirla? / Is it possible to prevent post-endoscopic retrograde cholangiopancreatography pancreatitis?

The frequency of post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis in a series of non-selected patients (average risk) varies between 3 and 10 percent. In high-risk patients, though, it may occur in up to 30 percent, and is considered a severe, and sometimes unpredictable and unavoidable complication. The identification of risk factors associated to the patient or to the procedure, the definition of the different steps that make part of an appropriate endoscopic technique, and the demonstration of the utility of drugs and endoscopic procedures that ensure adequate pancreatic duct drainage, have made it possible to determine which are the most suitable strategies for prevention. These are: a careful selection of the patients who will undergo ERCP, the use of an appropriate ERCP technique in all patients, the implantation of pancreatic prosthesis in high-risk post-ERCP patients, and the use of drugs in average- or high-risk patients. Currently, rectal anti-inflammatory drugs are the sole drug with proven efficacy according to clinical studies. The use of these strategies has shown that pancreatitis associated with the performance of an ERCP may be, in some cases, prevented and/or its severity rating may be lowered.

La frecuencia de pancreatitis post-colangiopancreatografía retrógrada endoscópica (CPRE) en series de pacientes no seleccionados (riesgo promedio) varía entre 3 y 10 por ciento, aunque en pacientes de alto riesgo puede presentarse hasta en 30 por ciento de ellos, considerándose una complicación grave y muchas veces impredecible e inevitable. La identificación de factores de riesgo asociados al paciente o al procedimiento, la definición de los diferentes puntos que forman parte de una adecuada técnica endoscópica, y la demostración de la utilidad de fármacos o procedimientos endoscópicos que aseguran un adecuado drenaje del conducto pancreático, han permitido definir las más adecuadas estrategias actualmente disponibles para su prevención. Estas son: una selección cuidadosa de los pacientes a quienes se realizará la CPRE, el uso de una técnica de CPRE adecuada en todos los pacientes, la instalación de prótesis pancreática en pacientes de alto riesgo de pancreatitis post CPRE, y el uso de fármacos en pacientes de riesgo promedio o alto. Actualmente los antiinflamatorios por vía rectal son la única droga con una eficacia comprobada en estudios clínicos. La utilización de estas estrategias ha demostrado que la pancreatitis asociada a la realización de una CPRE puede ser, en algunos casos prevenida, y en otros limitada en su gravedad.

Does allopurinol prevent post endoscopic retrograde cholangio pancreatography pancreatitis? a randomized double blind trial

Post endoscopic retrograde cholangiopancreatography [ERCP] pancreatitis is a frequent complication either for diagnosis or treatment of pancreatobiliary diseases. A number of pharmacological agents have been tried for prevention or alleviation of the complication. Allopurinol with free radical scavenger property has been considered as an effective prophylactic agent in some clinical trials. Administration of allopurinol in these trials was done in a long period before doing ERCP. Hence allopurinol converts to oxupurinol in the liver rapidly; it seems that clinical judgment about the net effect of allopurinol on prevention of post ERCP pancreatitis is doubtful. In this randomized double blind clinical trial, effect of allopurinol on prevention or alleviation of clinical and laboratory signs of pancreatitis has been evaluated in 74 patients undergoing ERCP. Results showed that there is not any difference between allopurinol and placebo in occurrence and severity of post ERCP pancreatitis [P=0.97]. Also there is not any significant difference in amylase rises between 2 groups in 8 and 16 hours after ERCP [P=0.947, 0.287 respectively]. Beneficial effects of allopurinol in some of the previous studies may be attributed to its active metabolite [oxypurinol]. Further studies recommended about the net effect of allopurinol and oxypurinol in the complication

Comparison of propofol and remifentanil administration on lipid profile

This study aimed to investigate the serum level of triglyceride, cholesterol, high density lipoprotein, low density lipoprotein, and very low density lipoprotein during administration of propofol and comparing it with infusion of remifentanil in patients undergoing sedation in ICU of Masih Daneshvari Hospital during 2005-2007. All patients with pulmonary disease, undergoing intubation and mechanical ventilation were enrolled in our study. The patients were randomly divided into two groups, first receiving propofol and second receiving remifentanil as the sedative agent. Lipid profile [triglyceride, cholesterol, high density lipoprotein, low density lipoprotein, and very low density lipoprotein] was checked before, immediately after, and the day after drug administration. A total of 40 patients were enrolled in this study, 20 of which took propofol and the remaining took remifentanil. The mean age of the patients was 58.67 +/- 18.57 yrs. Triglyceride and very low density lipoprotein[VLDL] were the two factors with statistically significant rise after infusion of propofol [p < 0.002]. Such a change was not detected in the remifentanil group. The other understudy factors did not show similar changes. Propofol infusion can induce dramatic rises in triglyceride and VLDL concentration even after low dose infusions and therefore special attention must be paid to patients prone to hyper-triglyceridemia and pancreatitis

Clinical trial of gabexate in the prophylaxis of post-endoscopic retrograde cholangiopancreatography pancreatitis

The objective of the present study was to determine the efficacy of prophylactic administration of gabexate for the prevention of post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis, hyperamylasemia and pancreatic pain. Patients scheduled for ERCP were randomized into two groups in a double-blind manner: the patients in the gabexate group were treated with continuous intravenous infusion of 300 mg gabexate dissolved in 500 mL Ringer's solution at 111 mL/h, starting 30 min before the endoscopic maneuvers and continuing up to 4 h after them; placebo group patients were treated only with Ringer's solution also starting 30 min before the endoscopic maneuvers and continuing up to 4 h. Data for 193 patients were analyzed. The incidence of post-ERCP pancreatitis was 3 patients (3.1 percent) in the gabexate group and 10 (10.5 percent) in the placebo group (P = 0.040). The incidence of hyperamylasemia was 33 patients (33.7 percent) in the gabexate group and 42 (43.7 percent) in the placebo group (P = 0.133). The incidence of pancreatic pain was 15 patients (15.3 percent) in the gabexate group and 28 (29.5 percent) in the placebo group (P = 0.018). The results suggest that a 4.5-h infusion of gabexate (for a total of 300 mg) could prevent post-ERCP pancreatitis and pancreatic pain.

Identificaçäo trans-operatória do óstio do Wirsung após a papilo-esfincteretomia / Intra-operative identification of the ostium of Wirsung's pancreatic duct after papilla-sphincterotomy

Objetivo. Contribuir para o achado do óstio de Wirsung durante a técnica da papiloesfincteroplastia, prevenindo a pancreatite aguda pós-operatória. Casuística e Método. Foram estudados 27 pacientes submetidos a papilo-esfincteroplastia por coledocolitíase com ou sem odite. Após a papiloesfincterotomia (PET) terapêutica, por via duodenal, realizou-se estudo da localizaçao do óstio do ducto de Wirsung. A PET transforma a ampola de Vater em um triângulo isósceles, cujas medidas foram obtidas através de compasso. Utilizando-as, o óstio do Wirsung poderá ser facilmente identificado e caracterizado no trans-operatório, antes de se fazer a sutura muco-mucosa da papila seccionada. Resultados. O óstio geralmente é encontrado medialmente na metade esquerda do triângulo e a uma distância média de 0,19cm a 0,25cm acima da base do triângulo, considerando-se a ausência ou presença de inflamaçao, respectivamente. Conclusao. A determinaçao transoperatória das distâncias padronizadas neste estudo, permite a detecçao e cateterizaçao segura do óstio do Wirsung na presença ou nao de odite.

Pancreatitis aguda recurrente / Acute pancreatitis recurrence

La pancreatitis aguda puede recurrir entre un 10 a un 20 por ciento en pacientes tratados y entre un 20 a un 40 por ciento en pacientes no tratados. Desde abril de 1987 a noviembre de 1994, hemos estudiado y tratado 221 pacientes con pancreatitis aguda, 154 de ellos (70 por ciento) tenían litiasis biliar, 23 de los 221, tuvieron dos o más ataques. Se determinó la severidad de cada ataque según un Score que clasifica dentro del rango 0,00 a 0,02 a las leves, de 0,21 a 0,40 a las moderadas y por encima de 0,40 a las graves. La pancreatitis crónica no fue considerada en este estudio. Las causas de recurrencias fueron litiasis biliar en 15 casos, idiopáticas en 8, dislipémicas en 3, páncreas divisum en 1 y medicamentosa en 1. Otros 50 pacientes (22 por ciento) tenían al ingreso del primer ataque un antecedente de pancreatitis aguda previa no certificada por nosotros. El primer ataque se ubicó en el rango de las leves: 0,19 ñ 0,08, el segundo en el moderadas: 0,28 ñ 0,06 (p < 0,05). Detectamos en total 3 casos graves (10,7 por ciento : 3/28), pero sin mortalidad. Siendo la litiasis biliar la causa más frecuente de incidencia en pancreatitis aguda (70 por ciento) y de la primera recurrencia en nuestro medio (53 por ciento)(12/23), todas las de causa idiopática deben ser consideradas litiásicas hasta que se demuestre lo contrario. Una vez certificada la litiasis biliar, ésta debe ser operada en la misma internación para prevenir las recurrencias
