ERCP Using Double-Balloon Enteroscopy in Patients with Roux-en-Y Anatomy

Double-balloon enteroscopy (DBE) is a useful method for endoscopic retrograde cholangiopancreatography (ERCP) in patients with Roux-en-Y anatomy. Depending on the distorted anatomy, endoscopic therapies with conventional scopes were very difficult or impossible before the advent of DBE and patients had to be submitted to a percutaneous or surgical approach. The case of 6 patients with different types of Roux-en-Y-altered anatomy in which DBE-ERCP was performed with 83.3% successful rate (5/6) is reported confirming recent data in the literature on the feasibility of this method.

Acute pancreatitis associated with acute viral hepatitis: case report and review of literature

This case report, along with the review presented, describes a patient diagnosed with acute viral hepatitis, who developed a framework of intense abdominal pain and laboratorial alterations compatible with acute pancreatitis. The association of acute pancreatitis complicating fulminant and non-fulminant acute hepatitis virus (AHV) has been reported and several mechanisms have been proposed for this complication, but so far none is clearly involved. As acute hepatitis is a common disease, it is important to stimulate the development of other studies in order to determine local incidence and profile of patients presenting this association in our environment.

C-reactive protein at 24 hours after hospital admission may have relevant prognostic accuracy in acute pancreatitis: a retrospective cohort study

Introduction: C-reactive protein (CRP) and Bedside Index for Severity in Acute Pancreatitis (BISAP) have been used in early risk assessment of patients with AP. Objectives: We evaluated prognostic accuracy of CRP at 24 hours after hospital admission (CRP24) for in-hospital mortality (IM) in AP individually and with BISAP. Materials and Methods: This retrospective cohort study included 134 patients with AP from a Portuguese hospital in 2009---2010. Prognostic accuracy assessment used area under receiver---operating characteristic curve (AUC), continuous net reclassification improvement (NRI), and integrated discrimination improvement (IDI). Results: Thirteen percent of patients had severe AP, 26% developed pancreatic necrosis, and 7% died during index hospital stay. AUCs for CRP24 and BISAP individually were 0.80 (95% confidence interval (CI) 0.65---0.95) and 0.77 (95% CI 0.59---0.95), respectively. No patients with CRP24 <60 mg/l died (P = 0.027; negative predictive value 100% (95% CI 92.3---100%)). AUC for BISAP plus CRP24 was 0.81 (95% CI 0.65---0.97). Change in NRI nonevents (42.4%; 95% CI, 24.9---59.9%) resulted in positive overall NRI (31.3%; 95% CI, − 36.4% to 98.9%), but IDI nonevents was negligible (0.004; 95% CI, − 0.007 to 0.014). Conclusions: CRP24 revealed good prognostic accuracy for IM in AP; its main role may be the selection of lowest risk patients.

Contributo da C.P.R.E./E.T.E. na Terapêutica da Pancreatite Aguda Litiásica

Na literatura médica existem actualmente vários trabalhos confirmando o valor da Colangiopancreatografla Retrógada Endoscópica (C.P.R.E.) e da Esflncterotomia Endoscópica (E.T.E.) na terapêutica da Pancreatite Aguda Litiásica (P.A.L.). E uma técnica endoscópica de primeira linha na actuação terapêutica na P.A.L. que ao permitir desobstruir as vias biliares de cálculos elimina o factor etiológico desencadeante da doença. E a experiência do grupo de C.P.R.E./E.T.E. do Hospital dos Capuchos que iremos dar a conhecer no presente trabalho.

C-reactive protein in early risk assessment in acute pancreatitis

ABSTRACT:C-reactive protein (CRP) has been widely used in the early risk assessment of patients with acute pancreatitis (AP), but unclear aspects about its prognostic accuracy in this setting persist. This project evaluated first CRP prognostic accuracy for severity, pancreatic necrosis (PNec), and in-hospital mortality (IM) in AP in terms of the best timing for CRP measurement and the optimal CRP cutoff points. Secondly it was evaluated the CRP measured at approximately 24 hours after hospital admission (CRP24) prognostic accuracy for IM in AP individually and in a combined model with a recent developed tool for the early risk assessment of patients with AP, the Bedside Index for Severity in AP (BISAP). Two single-centre retrospective cohort studies were held. The first study included 379 patients and the second study included 134 patients. Statistical methods such as the Hosmer-Lemeshow goodness-of-fit test, the area under the receiver-operating characteristic curve, the net reclassification improvement, and the integrated discrimination improvement were used. It was found that CRP measured at approximately 48 hours after hospital admission (CRP48) had a prognostic accuracy for severity, PNec, and IM in AP better than CRP measured at any other timing. It was observed that the optimal CRP48 cutoff points for severity, PNec, and IM in AP varied from 170mg/l to 190mg/l, values greater than the one most often recommended in the literature – 150mg/l. It was found that CRP24 had a good prognostic accuracy for IM in AP and that the cutoff point of 60mg/l had a negative predictive value of 100%. Finally it was observed that the prognostic accuracy of a combined model including BISAP and CRP24 for IM in AP could perform better than the BISAP alone model. These results might have a direct impact on the early risk assessment of patients with AP in the daily clinical practice.--------- RESUMO: A proteina c-reactiva (CRP) tem sido largamente usada na avaliação precoce do risco em doentes com pancreatite aguda (AP), mas aspectos duvidosos acerca do seu valor prognóstico neste contexto persistem. Este projecto avaliou primeiro o valor prognóstico da CRP para a gravidade, a necrose pancreática (PNec) e a mortalidade intra-hospitalar (IM) na AP em termos do melhor momento para efectuar a sua medição e dos seus pontos-de-corte óptimos. Em segundo lugar foi avaliado o valor prognóstico da proteína c-reactiva medida aproximadamente às 24 horas após a admissão hospitalar (CRP24) para a IM na AP isoladamente e num modelo combinado, que incluiu uma ferramenta de avaliação precoce do risco em doentes com AP recentemente desenvolvida, o Bedside Index for Severity in Acute Pancreatitis (BISAP). Dois estudos unicêntricos de coorte retrospectivo foram realizados. O primeiro estudo incluiu 379 doentes e o segundo estudo incluiu 134 doentes. Metodologias estatísticas como o teste de Hosmer-Lemeshow goodness-of-fit, a area under the receiver-operating characteristic curve, o net reclassification improvement e o integrated discrimination improvement foram usadas. Verificou-se que a CRP medida às 48 horas após a admissão hospitalar (CRP48) teve um valor prognóstico para a gravidade, a PNec e a IM na AP melhor do que a CRP medida em qualquer outro momento. Observou-se que os pontos de corte óptimos da CRP48 para a gravidade, a PNec e a IM na AP variaram entre 170mg/l e 190mg/l, valores acima do valor mais frequentemente recomendado na literatura – 150mg/l. Verificou-se que a CRP medida aproximadamente às 24 horas após a admissão hospitalar (CRP24) teve um bom valor prognóstico para a IM na AP e que o ponto de corte 60mg/l teve um valor preditivo negativo de 100%. Finalmente observou-se que o valor prognóstico de um modelo combinado incluindo o BISAP e a CRP24 para a IM na AP pode ter um desempenho melhor do que o do BISAP isoladamente. Estes resultados podem ter um impacto directo na avaliação precoce do risco em doentes com AP na prática clínica diária.

Hepatocyte metaplasia in experimental chagasic pancreatitis: preliminary report

Beginning the study of chronic pathologic changes in pancreas of hamsters experimentally infected with Trypanosoma cruzi Vic strain, hepatocyte metaplasia was observed in one animal from infected group. This is the first report of oncocytes in Chagas' disease, which could be due to aberrant regenerative response to pancreas inflammatory process.

Recurrent Acute Pancreatitis and Therapy for Ulcerative Colitis.

Drugs are a rare cause of pancreatitis. Whereas some drugs are well known to induce an attack of pancreatitis, some people may be more prone to develop pancreatitis because of personal susceptibility. We describe a recurrent case of acute pancreatitis after administration of several drugs in a patient with intestinal inflammatory bowel disease that needed to be treated with subsequent antiinflammatory agents. Genetic mutation in the CFTR gene was found in the patient that led us to postulate that CFTR was a trigger for drug-induced acute pancreatitis. In conclusion, genetic analysis should be advised in case of recurrent pancreatitis in patient with intestinal inflammatory bowel disease.

Paper de la PAP en la resposta inflamatoria durant la pancreatitis aguda

Estudi elaborat a partir d’una estada al Institut national de la santé et de la recherche médicale, França, entre setembre i octubre del 2006. La PAP va ser identificada inicialment com una proteïna de secreció, que apareixia al suc pancreàtic després de la inducció d’una pancreatitis aguda experimental. Per la PAP s’ha suggerit diferents funcions, algunes no relacionades en aparença, però les més interessants en el camp de la pancreatitis són les activitats antiapoptótiques, mitogéniques i, especialment, antiinflamatóries. Per aprofundir en aquests aspectes de la PAP, s’ha emprat un model de ratolí PAP-/- per observar els efectes de la deleció del gen de la PAP durant la pancreatitis aguda.Per induir la pancreatitis es va fer servir el model de administració de ceruleina a dosi supra-màximes. En aquestes condicions es va observar que en els animals PAP-/-, la severitat del procés era menor. Els marcadors de necrosi pancreàtica, lipasa i amilasa, van presentar nivells menors en els animals PAP-/- que en els corresponents wild type. Per contra, el nombre de PMN infiltrats i la producció de citoquines pro-inflamatories va ser major en el pàncreas dels animals PAP-/-. La intensitat de la resposta inflamatòria observada suggereix que en condicions fisiològiques, el paper anti-inflamatori de la PAP es prou rellevant. Això ja s’havia suggerit en estudis in vitro, en els que es va demostrar que l’activitat antiinflamatòria de la PAP depenia de la via de transducció de senyal Jak/STAT/SOCS3. Aquesta hipòtesi s’ha comprovat in vivo, monitoritzant el nivell d’activació de STAT3 en els pàncreas dels animals després de la inducció de la pancreatitis.Tot plegat confirma que les funcions antiinflamatòries descrites in vitro per la PAP també es poden observar in vivo, de manera que la PAP sembla ser un agent important en la resposta de les cèl•lules pancreàtiques durant la pancreatitis aguda.

Valoració de la introducció d’un protocol diagnòstic-terapèutic de la pancreatitis aguda fent especial èmfasi en els marcadors precoços de gravetat

Del 10 al 20% de les pancreatitis agudes(PA) són greus. L’objetiu del treball és la valoració dels marcadors precoços de gravetat. Es presenta un estudi prospectiu de 130 pacients amb PA analitzant les classificacions de Ranson, Apache II, Índex de Severitat del TAC(IST), hematòcrit i PCR en les primeres 24h comparant-los amb els criteris d’Atlanta. La proporció de necrosi, d’ingrés a UCI i de mortalitat obtingudes en la sèrie estudiada en el nostre entorn són similars als de la literatura. Segons els nostres resultats l’hematòcrit en les primeres 24hores és predictor de mortalitat i l’Apache II d’ingrés a UCI.

Variables asociadas a necrosis pancreática en pacientes con Pancreatitis Aguda Grave.

Hem fet un estudi retrospectiu de 73 adults amb pancreatitis aguda greu recollint variables analítiques i radiològiques a l'ingrés i a les 48h i relacionant-les amb l'existència de necrosi pancreàtica a la TC. Les variables relacionades amb la necrosi van ser: edat, leucòcits, VSG, TP, INR, glucèmia, urea, creatinina, proteïnes, albúmina, LDH, calci, PCR i presència de vessament pleural a la Rx. D'aquestes, el vessament pleural a l'ingrés i la hipoalbuminemia, les xifres altes de LDH i PCR a les 48 hores es van relacionar significativament, la qual cosa permet identificar pacients amb major risc en els quals instaurar mesures precoces

Anti-TNF Therapy in the Treatment of Psoriasis in a Patient with Acute-on-Chronic Pancreatitis.

Background: Psoriasis is accepted as a multisystemic disease with several important systemic manifestations. Thus, underlying comorbidities have to be taken into account in the choice of treatment. Objective: To explore the role of anti-TNF therapy in the treatment of psoriasis in a patient with acute-on-chronic pancreatitis. Methods: Here, we present the case of a 75-year-old patient with severe psoriasis also suffering from chronic alcohol-induced pancreatitis with recurrent acute flares. A recent life-threatening episode of acute pancreatitis and ischemic liver precluded the reintroduction of methotrexate. Cyclosporine was also excluded as it has been reported to induce acute pancreatitis. Thus, an anti-TNF treatment was initiated in close collaboration with a gastroenterologist. Results: A year after starting anti-TNF therapy the patient continues to show complete clinical remission of his psoriasis. No side effects, particularly no bacterial infections, were reported. No relapses of the patient's underlying chronic pancreatitis were observed throughout the entire treatment with regular clinical and laboratory monitoring, suggesting that chronic pancreatitis is not per se a contraindication for anti-TNF therapy. Conclusion: This case study opens the way for further questioning on the role of TNF in the pathogenesis of chronic and acute pancreatitis and the use of anti-TNF therapy in its treatment. © 2013 S.

Duodenal duplication cyst and pancreas divisum causing acute pancreatitis in an adult male acute pancreatitis in an adult male

Duodenal duplication cysts are rare congenital abnormalities which are more commonly diagnosed in infancy and childhood. However, in rare cases, these lesions can remain asymptomatic until adulthood. The combination of duplication cyst and pancreas divisum is extremely rare and both conditions have been linked with acute recurrent pancreatitis. We present the case of a 37 years-old patient who presented with repeated episodes of acute pancreatitis. By means of magnetic resonance imaging and endoscopic ultrasonography we discovered a duplication cyst whose cavity received drainage from the dorsal pancreas. After opening the cyst cavity to the duodenal lumen with a needle knife the patient presented no further episodes in the clinical follow-up. Comparable literature findings and therapeutic options for these abnormalities are discussed with regard to the presented case.
