Eurytrema coelomaticum is a trematode reported in the pancreatic ducts of ruminants. It is conjectured that may cause disorders in the pancreas, as well as digestive and metabolic processes dependent on them. This study, determined if there is an impairment of exocrine pancreatic function, and correlated it with parasite burden. Pancreas, blood, and fecal samples were collected from 119 bovines at a abattoir. Stool samples were subjected to the gelatin and x-ray film digestion tests (to detect the presence of trypsin in feces). Using blood samples, the following biochemical tests were performed: amylase, lipase, glucose, fructosamine, cholesterol, triglycerides, total protein, albumin, and globulins. Analyses were correlated with pancreatic parasite burden. Cattle with a high parasitic load presented higher incidence of negative tests in both gelatin digestion and x-ray film digestion tests (P < 0.001) when compared to non-parasitized animals and those with a low parasitic load. Changes in those tests only occurred if the parasitemia was moderate or severe. The activity of the amylase and lipase enzymes was significantly higher in animals with low parasitemia (P < 0.05), compared to non-parasitized animals and with a high parasitic burden. In this study, in cases of high parasitemia, negative results were observed in both gelatin and x-ray film in the feces digestion tests. However, the low infection of E. coelomaticum, higher levels of serum amylase and lipase that also indicated loss of pancreatic exocrine functions were reported.

Eurytrema coelomaticum, um trematódeo de ductos pancreáticos de ruminantes. Conjectura-se que possa ocasionar transtornos nas funções pancreáticas, mais especificamente nos processos digestivos e metabólicos dependentes destas. Neste estudo, o objetivo foi determinar se há comprometimento da função pancreática exócrina, correlacionado-a a carga parasitária. Foram utilizados pâncreas e respectivas amostras de sangue e fezes de 119 bovinos. As amostras de fezes foram submetidas aos testes de digestão da gelatina em tubo e digestão de filme radiográfico, ambos para detecção de tripsina nas fezes. Foram realizados os seguintes exames bioquímicos em amostras de sangue: amilase, lipase, glicemia, frutosamina, colesterol, triglicerídeos, proteínas totais, albumina e globulinas. Após isto, as análises bioquímicas foram correlacionadas com a quantidade numérica de parasitas encontrados no pâncreas (post-mortem). Houve maior quantidade de testes negativos (digestão do filme radiográfico e prova de digestão da gelatina) nos animais com alta carga parasitária (P < 0.001), quando comparados aos animais não parasitados e com baixa carga parasitária. Portanto, os exames supracitados se alteram somente se a quantidade de parasitas for moderada ou severa. As atividades das enzimas amilase e lipase foram significativamente maiores nos animais que apresentavam baixa parasitemia (P < 0.05), em comparação com os animais com alta carga parasitária e não parasitados. Conclui-se que em quadros de alta parasitemia há alteração significativa nos testes de digestão nas fezes, e que em quadros de baixa parasitemia há alterações significativas nos valores de amilase e lipase séricas, ambos comprovando alterações pancreáticas importantes, de acordo com o quadro de parasitemia.

OBJECTIVE@#To assess the effect of early abdominal puncture drainage (APD) on autophagy and Nrf-2/HO-1 pathway in rats with severe acute pancreatitis (SAP) and explore the possibile mechanism.@*METHODS@#Thirty-two male SD rats were randomly divided into sham-operated (SO) group, SAP group with retrograde injection of 4% sodium taurocholate, APD group with insertion of a drainage tube into the lower right abdomen after SAP induction, and APD + ZnPP group with intraperitoneal injection of 30 mg/kg ZnPP 12 h before APD modeling. Blood samples were collected from the rats 12 h after modeling for analysis of amylase and lipase levels and serum inflammatory factors. The pathological changes of the pancreatic tissue were observed with HE staining. Oxidative stress in the pancreatic tissue was detected with colorimetry, and sub-organelle structure and autophagy in pancreatic acinar cells were observed by transmission electron microscopy. The expressions of autophagy-related proteins and Nrf-2/HO-1 pathway were detected using RT-PCR and Western blotting.@*RESULTS@#Compared with those in SAP group, the rats with APD treatment showed significantly alleviated pathologies in the pancreas, reduced serum levels of lipase, amylase and inflammatory factors, lowered levels of oxidative stress, and activated expressions of Nrf-2/HO-1 pathway in the pancreas. The ameliorating effect of ADP was significantly inhibited by ZnPP treatment before modeling. APD obviously reversed mitochondrial and endoplasmic reticulum damages and p62 accumulation induced by SAP.@*CONCLUSION@#APD treatment can suppress oxidative stress and repair impaired autophagy in rats with SAP by activating the Nrf-2/HO-1 pathway, thereby reducing the severity of SAP.

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.

Galunisertib (LY2157299), a selective ATP-mimetic inhibitor of TGF-β receptor I (TGF-βRI), is the only known TGF-β pathway inhibitor. In the present study, we investigated the effect of galunisertib on taurocholate (TAC)-induced acute pancreatitis (AP) in rats, and the role of TGF-β and NF-κB signaling pathways. AP was induced by infusion of TAC into the pancreatic duct of Sprague-Dawley male rats (n=30). The rats (220±50 g) were administered galunisertib intragastrically [75 mg·kg-1·day-1 for 2 days (0 and 24 h)]. Serum IL-1β, IL-6, TNF-α, amylase (AMY), lipase (LIP), and myeloperoxidase (MPO) levels were measured by ELISA. NF-κB activity was detected by electrophoretic mobility shift assay (EMSA); NF-κBp65 and TGF-β1 proteins, as well as TGF-βRI and p-Smad2/3 proteins, were detected by western blot assay. Cell apoptosis was detected by TUNEL assay. H&E staining was used to evaluate the histopathological alterations of the pancreas. Galunisertib treatment attenuated the severity of AP and decreased the pancreatic histological score. In addition, number of apoptotic cells were significantly increased in the galunisertib-treated group (16.38±2.26) than in the AP group (8.14±1.27) and sham-operated group (1.82±0.73; P<0.05 and P<0.01, respectively). Galunisertib decreased the expression levels of TGF-βRI and p-Smad2/3 and inhibited NF-κB activation and p65 translocation compared with the sham-operated group. Furthermore, serum IL-1β, IL-6, TNF-α, AMY and LIP levels and tissue MPO activity were significantly decreased in the galunisertib-treated group. Our data demonstrate that galunisertib attenuates the severity of TAC-induced experimental AP in rats by inducing apoptosis in the pancreas, inhibiting the activation of TGF-β signals and NF-κB as well as the secretion of pro-inflammatory cytokines.

A significant increase in serum lipase, amylase, capase-1 and myeloperoxidase activities, oxidative stress index (OSI), IL-1β and IL-18 was observed in rats receiving ethanol (EtOH) and high fat diet (HFD). Thymoquinone (TQ) supplementation along with EtOH and HFD significantly decreased the levels of serum lipase, amylase, capase-1, myeloperoxidase, OSI and maintained the antioxidant status when compared to untreated EtOH and HFD fed rats. Among the 4 doses, 100 mg of TQ/kg body weight was found to provide optimum protective effect on pancreas against EtOH and HFD induced abnormal changes. Histological observations added more evidence for the anti-inflammatory effect of TQ.

PURPOSE: Acute pancreatitis is one of the potentially lethal complications that occurs after cardiac surgery. We tried to identify risk factors for and the prognosis of acute pancreatitis after cardiac valve surgery with cardiopulmonary bypass. MATERIALS AND METHODS: We retrospectively analyzed a database of consecutive patients who underwent cardiac valve surgery with cardiopulmonary bypass between January 2005 and April 2010 at our institution. Patients were classified as having acute pancreatitis based on serum lipase concentration and clinical symptoms (lipase > or =180 U/L or > or =60 U/L with relevant symptoms). RESULTS: Of the 986 patients who underwent cardiac valve surgery with cardiopulmonary bypass, 58 (5.9%) patients developed post-operative pancreatitis. Post-operative hospital stay was significantly longer (29.7+/-45.6 days vs. 12.4+/-10.7 days, p=0.005) and in-hospital mortality rate was higher (15.5% vs. 2.0%, p<0.001) in patients with post-operative pancreatitis than those without. Hypertension, chronic kidney disease, and peri-operative use of norepinephrine were identified as independent risk factors for developing pancreatitis after cardiac valve surgery. CONCLUSION: We found that acute pancreatitis after cardiac valve surgery requires longer hospitalization and increases the in-hospital mortality rate. Clinicians should be aware that patients could develop pancreatitis after cardiac valve surgery, especially in patients with hypertension and chronic kidney disease treated with norepinephrine.

Background. Pancreaticobiliary reflux is a pathologic phenomenon occurring in patients with gallstones. However, the occurrence of pancreaticobiliary reflux has not been studied in patients without gallstones. The objective of this study was to measure the bile levels of amylase and lipase in patients without gallstones submitted to cholecystectomy as part of another surgical procedure, and to compare these values with patients submitted to cholecystectomy for gallstone disease. Patients and Methods. A prospective observational comparative study was designed. A sample of 136 consecutive patients was included. Amylase and lipase levels were measured in bile. Normal serum amylase levels at our institution are 28-100 U/L and for lipase are 13-60 U/L. There are no established normal levels for pancreatic enzymes in bile. However, we considered elevated the bile amylase and lipase levels whenever they were higher than normal plasma levels. Results. One-hundred three patients (76 percent) had gallstones and 33 (24 percent) liad healthy gallbladders without gallstones. According to normal plasma levels for amylase and lipase, these enzymes in bile were elevated in 83.5 percent patients with gallstones, compared to elevated levels of amylase in 6 percent patients and lipase in 3 percent patients without gallstones. Conclusions. Pancreaticobiliary reflux is a common phenomenon in patients with gallstones and occurs sporadically in patients without gallstones.

Introducción. El reflujo pancreáticobiliar es un fenómeno patológico que ocurre en pacientes con colelitiasis. La ocurrencia de este fenómeno no ha sido estudiada en pacientes sin colelitiasis. El presente estudio tiene por objetivo medir los niveles de amilasa y lipasa en la bilis de pacientes sin colelitiasis, colecistectomizados como parte de otro procedimiento quirúrgico y comparar estos valores con pacientes colecistectomizados por colelitiasis. Pacientes y Métodos. Se diseñó un estudio observacional y comparativo. Una muestra de 136 pacientes consecutivos fue incluida. Se midieron los niveles de amilasa y lipasa en la bilis. En nuestra institución los valores normales para amilasa son 28-100 U/L y para lipasa 13-60 U/L. No se han establecido valores normales de enzimas pancreáticas en la bilis. Para efectos del presente estudio, se consideró como elevados los niveles biliares de amilasa y lipasa cuando fueron mayores a los valores plasmáticos normales. Resultados. 103 pacientes (76 por ciento) tenían colelitiasis y 33 (24 por ciento) tenían vesículas normales sin cálculos. De acuerdo a los valores plasmáticos normales de amilasa y lipasa, estas enzimas se encontraron elevadas en 83,5 por ciento de los pacientes con colelitiasis comparados con valores elevados de amilasa en 6 por ciento en pacientes sin colelitiasis y de lipasa en 3 por ciento de estos pacientes. Conclusiones. El reflujo pancreaticobiliar es un fenómeno común en pacientes con colelitiasis y ocurre esporádicamente en pacientes sin colelitiasis.

The most common pancreatic cancer is adenocarcinoma. Primary adenosquamous cell carcinoma of the pancreas is very rare and aggressive. A 46-year-old man presented with a 3-month history of dyspepsia and a 7-kg weight loss. The physical examination showed tenderness of the right upper quadrant of the abdomen. There was no jaundice. Amylase and lipase were elevated. CA 19-9 was elevated to 566.7 U/mL. Gastroduodenoscopy showed a hard ulceroinfiltrative mass with a yellowish exudate that bled readily on touch in the second portion of the duodenum. Abdominal computed tomography showed a 7.1 x 6.3-cm heterogeneously enhancing mass in the pancreatic head. The pancreatic mass had invaded the duodenum wall, gastric antrum, and gastroduodenal artery sheath. Fine-needle aspiration biopsy of the pancreatic mass revealed adenosquamous cell carcinoma, anaplastic type. We concluded that an adenosquamous cell carcinoma of pancreas had invaded the duodenal mucosa causing ulceration.

Pancreatitis complicating a diagnosis of systemic lupus erythematosus (SLE) is rarely reported in the literature and there are no known published cases thus far in the Caribbean. A 50-year old female diagnosed with SLE and discoid lupus erythematosus (DLE) since 1990, presented in February, 2009, to the University Hospital of the West Indies (UHWI), Kingston, Jamaica, with symptoms suggestive of lupus pancreatitis. Serum amylase level was 2341 IU/L and serum lipase was 203 IU/L. Pancreatitis has a 3-8% rate of occurrence in adult patients with SLE. Aetiology and management of this entity remains controversial in these cases, but one must bear the diagnosis in mind, when faced with a SLE patient presenting with abdominal pain, vomiting and diarrhoea.

La pancreatitis que complica el diagnóstico del lupus eritematoso sistémico (LES), raramente se reporta en la literatura, y hasta hoy no se conoce de caso alguno publicado en el Caribe. Una mujer de 50 años de edad, a quien se le diagnosticara lupus eritematoso sistémico (LES), y lupus eritematoso discoide (LED) desde 1990, acudió en febrero de 2009 al Hospital Universitario de West Indies, Kingston, Jamaica, con síntomas que sugerían una pancreatitis por lupus. El nivel de amilasa sérica fue 2341 IU/L y el de lipasa sérica fue 203 IU/L. La pancreatitis tiene una tasa de ocurrencia de 3-8% en pacientes adultos con LES. La etiología y el tratamiento de esta entidad siguen siendo controversiales en estos casos, pero se debe tener presente el diagnóstico frente a pacientes de SLE que presenten dolor abdominal, vómito y diarrea.

Acute pancreatitis is a common and dreaded complication of endoscopic retrograde cholangiopancreatography [ERCP] patients. The study identified the incidence of post ERCP pancreatitis and role of serum calprotectin and ghrelin in its diagnosis. One hundred forty two patients underwent ERCP-related procedures were studied. Serum amylase, lipase, calprotectin and ghrelin concentrations were measured 24 hours after the procedure using ELISA, kinetic and colorimetric methods. Thirty two healthy controls were enrolled. In post ERCP group, mean level of amylase was 146.03 +/- 57.40 U/L, lipase 328.37 +/- 133.95 U/L, calprotectin 3.26 +/- 2.99 U/L and gherkin 2.56 +/- 1.76 mg/l. In controls mean level of amylase was 58.13 +/- 15.96U/L, lipase 18 1.63 +/- 5 1.94 U/L, calprotectin 0.49 +/- 0.17UL and ghrelin 2.59 +/- 0.19 mg/1. A statistical significant increase was reported [p<0.001] in levels of amylase, lipase and calprotectin between the two groups without significant in ghrelin level

Pancreatitis has been occasionally associated with Crohn's disease (CD). A definite etiology of pancreatitis can be identified in most patients, but a very small proportion remain idiopathic. We report a case of idiopathic pancreatitis resolved along with the clinical improvement of CD in a 25-year-old man. He presented with abdominal pain and diarrhea for 8 years. Ileocolonoscopy and enteroclysis showed multiple, longitudinal ulcers and strictures at the ileojejunum. The laboratory findings showed elevated serum amylase (951 IU/L) and lipase (326 IU/L) without positive autoantibodies. Esophagogastroduodenoscopy, enhanced pancreatic CT, and MRCP showed no abnormalities at ampulla of Vater, pancrease, and pancreaticobiliary duct. With the treatment with antibiotics, 5-aminosalicylic acid, steroid, and azathioprine, as a whole, decreasing pattern and intermittent fine coordinated fluctuation of the levels of amylase and lipase along with the decrease of Crohn's disease activity index (CDAI) and the CRP levels were observed. Then, three months after the start of the treatment, normalization of the pancreatic enzymes was observed, and there was recurrent elevation of pancreatic engyme during 12 months maintenance therapy. This report supports the concept of an association between idiopathic pancreatitis and CD, based on a significant and close relation between the levels of serum amylase and lipase, and CDAI.

RACIONAL: Pancreatites agudas de causas alcoólica ou biliar podem necessitar de abordagens terapêuticas diferentes. OBJETIVO: Verificar a validade da relação lipase/amilase em diferenciar as causas alcoólica ou biliar na pancreatite aguda/pancreatite crônica agudizada. MÉTODOS: Foram avaliados nove pacientes com pancreatite aguda/pancreatite crônica agudizada alcoólica, todos homens, com idade média (desvio padrão) de 39,8 ± 7,0 anos (grupo I) e 29 com pancreatite aguda biliar, sendo 8 homens e 21 mulheres, com idade média de 43,6 ± 19,9 anos (grupo II). As amilasemias e lipasemias foram determinadas em pacientes com sintomatologia há, no máximo, 48 horas. A relação lipase/amilase foi calculada utilizando-se valores de amilasemia e lipasemia expressas como múltiplos de seus respectivos valores superiores de referência. RESULTADOS: As médias das lipasemias (4.814 ± 3.670 U/L) e amilasemias (1.282 ± 777 U/L) no grupo I foram semelhantes às do grupo II (2.697 ± 2.391 e 1.878 ± 1.319 U/L, respectivamente), mas a média das relações lipase/amilase foi significantemente maior no grupo I (4,4 ± 3,6) do que no grupo II (2,2 ± 2,2). Relação lipase/amilase >3 foi significantemente mais freqüente no grupo I (66,7 por cento) do que no grupo II (24,1 por cento) e diferenciou os dois grupos com sensibilidade de 67 por cento e especificidade de 76 por cento. CONCLUSÕES: 1) as amilasemias e lipasemias não diferenciaram os dois grupos avaliados; 2) relação lipase/amilase >3 é mais freqüente na pancreatite aguda/pancreatite crônica agudizada alcoólica do que na pancreatite aguda biliar, e pode ser útil na diferenciação destas duas causas de pancreatite.

BACKGROUND: Alcoholic or biliary acute pancreatitis may need different therapeutic approaches. AIM: Assessing the validity of lipase/amylase ratio in differentiating biliary from alcoholic acute pancreatitis/acutized chronic pancreatitis. METHODS: Nine male patients (mean age and standard deviation: 39.8 ± 7.0 years) with alcoholic acute pancreatitis/acutized chronic pancreatitis (group I) and 29 patients, 8 male and 21 female (mean age: 43.6 ± 19.9 years), with biliary acute pancreatitis (group II) were evaluated. Serum lipase and amylase levels were measured in patients with symptoms for no more than 48 hours. The lipase/amylase ratio was calculated based on serum lipase and amylase levels and expressed as multiples of their respective superior reference values. RESULTS: Mean levels of serum lipase (4,814 ± 3,670 U/L) and amylase (1,282 ± 777 U/L) in patients of group I were comparable to group II (2,697 ± 2,391 and 1,878 ± 1,319 U/L, respectively), but the mean lipase/amylase ratio was significantly higher in group I (4.4 ± 3.6) than in group II (2.2 ± 2.2). Lipase/amylase ratio >3 occurred at significantly higher proportions in patients of group I (66.7 percent) than of group II (24.1 percent), differentiating the two groups with sensitivity of 67 percent and specificity of 76 percent. CONCLUSIONS: 1) Amylase and lipase serum levels did not differ in the two groups evaluated; 2) the lipase/amylase ratio >3 was more often seen in alcoholic acute pancreatitis/acutized chronic pancreatitis than biliary acute pancreatitis, and it may be useful in differentiating these two causes of pancreatitis.

Acute pancreatitis [AP] is a complex disease associated with significant complications and a high rate of mortality. The aim of this work was to study the effect of the antioxidant melatonin on cerulein-induced pancreatitis in adult male albino rats. Thirty two adult male albino rats were used and randomly divided into four groups: first group [control]; second group [melatonin treated]; third group [cerulein treated] and fourth group [melatonin and cerulein treated group]. At sacrifice, blood samples were drawn for biochemical study and pancreas specimens were prepared for histological, and histochemical study. Melatonin reduced serum amylase and lipase activities, which were highly significantly elevated in cerulein induced pancreatitis. Histologically there was wide separation between pancreatic lobules, the acinar cells showed degeneration and vacuolation and lost their zymogen granules. There was dilatation and congestion of blood vessels, interstitial hemorrhage and cellular infiltration. Ultrastructurally, there was disorganized dilated rough endoplasmic reticulum [RER], marked decrease in zymogen granules, mitochondrial damage and cytoplasmic vacuoles. Immunohistochemically, pancreatic sections of cerulein treated rats showed a strong immune reaction for transforming growth factor-beta [TGF-beta] and vascular endothelial growth factor [VEGF]. Melatonin improved the biochemical, histological, and histochemical picture of pancreas.

BACKGROUD: Biliary cannulation to perform endoscopic retrograde cholangiopancreatography may be difficult due to technical reasons and often is necessary to perform papillotomy, where complications as pancreatitis and perforation may occur AIM: To show minimal complications by a new model of biliary access by means of the suprapapillary needle puncture and its laboratory profile. PATIENTS AND METHODS: After the approval of the protocol by the Scientific Ethics Committee of the institution a free and informed consent was signed by all patients participating in the study. From July 2003 to August 2004, fulfilling the inclusion and exclusion criteria, 30 patients were selected for endoscopic retrograde cholangiopancreatography, using the suprapapillary puncture technique. All patients remained hospitalized, fasting and with basal hydroelectrolytic replacement, were clinically followed up and samples for the determination of serum amylase, lipase and C-RP (C-reactive protein) were collected before and 4 h, 12 h and 24 h after the procedure and reevaluated 60 days after the procedure. Laboratory parameters were submitted to statistical study using analysis of variance for repeated measurements. Multiple comparisons were made based on Wald's statistics RESULTS: The technique was successful in 93.4 percent (28/30) of the patients. No statistically significant difference regarding to the laboratory profile were observed. Complications related to the technique of papillary puncture occurred in 1/28 patients by not using the guide wire and in 1/28 where mild hemorrhage after dilation of the papillary fistula occurred. Regarding complications related to therapeutic procedures, there were 2/28 retroduodenal perforations, with one (1/30) following unsuccessful puncture and another due to the passage of Dormia's basket through the dilated fistula path. All patients submitted to diagnostic puncture and evaluated 60 days after the procedure presented...

RACIONAL: A cateterização para acesso às vias biliares na colangiopancreatografia retrógrada pode apresentar dificuldades técnicas, sendo necessário freqüentemente efetuar-se papilotomia, procedimento não isento de complicações como perfuração e pancreatite OBJETIVOS: Demonstrar menor incidência de complicações a partir do perfil laboratorial, através de nova técnica desenvolvida, a punção suprapapilar MATERIAL E MÉTODOS: Após aprovação pelo Comitê de Ética em Pesquisa da instituição, 30 pacientes foram selecionados no período de julho de 2003 a agosto de 2004. Preenchidos os critérios de inclusão e exclusão, os pacientes, após explicação do protocolo e a assinatura do consentimento livre e esclarecido, foram submetidos a colangiopancreatografia retrógrada pela técnica de punção suprapapilar. Após o procedimento, foi feito seguimento com o paciente internado para avaliar possíveis complicações, bem como determinação dos níveis séricos da amilase, lipase e proteína C reativa nas 4 h, 12 h e 24 h subseqüentes e reavaliados 60 dias após. O estudo estatístico foi feito por análise de variância para medidas múltiplas e comparações múltiplas foram feitas por meio do teste de Wald RESULTADOS: O sucesso da técnica ocorreu em 93,4 por cento (28/30) dos pacientes. Não foram observadas alterações estatisticamente significantes no perfil laboratorial. Complicações relacionadas à técnica de punção ocorreram em dois pacientes: um pelo não uso do fio guia e em outro por hemorragia, após dilatação da papila. Relacionadas ao procedimento, ocorreram duas perfurações retroduodenais: uma decorrente de punção e outra após passagem do cesto de Dormia pela fístula dilatada. Após seguimento de 60 dias, nenhuma complicação foi observada CONCLUSÃO: Punção suprapapilar permite procedimentos investigativos e terapêuticos sem aumento significativo da amilase, lipase e proteína C reativa. Na punção diagnóstica ocorre reepitelização completa da papila, enquanto na...
