          Abstract

          El objetivo del estudio fue establecer la utilidad de la proteína C reactiva (PCR) como marcador de severidad en pacientes con pancreatitis aguda (PA), evaluados en el Servicio de Gastroenterología del Hospital Universitario de Maracaibo. Durante los meses de Marzo a Diciembre de 2006. Materiales y Métodos: Estudio prospectiva, descriptiva, correlacional, Se analizaron las variables: edad, sexo, formas clínicas, etiología, criterios de Ranson, grados de Baltazar y valores de PCR. La PCR se determinó mediante técnica cuantitativa, utilizando reactivo de látex. Resultados: Se estudiaron 35 pacientes con predomino del sexo femenino 20 (57,14%) y mas frecuente entre la tercera y cuarta década de la vida. En relación a los criterios de Ranson 25 (71,43%) presentaron menos de 3 criterios de Ranson, con valores de PCR entre 8 y 128 mg/dl, 10 (28,57%) obtuvieron º 3 criterios de Ranson y el rango de PCR entre 128 a 256 mg/dl, (p= 0,0011).Se demostró asociación positiva entre las cifras de PCR y criterios de Ranson (r= 0,871, p=0,0001) y no se observó entre PCR y Baltazar. Predominó la PA de etiología biliar en 16 (45,71%) El promedio 146,28μ80,22 de PCR encontrados en pacientes con PA alcohólica fue ligeramente superior al compararlo con las otras causas. Conclusión: La PCR es una prueba de laboratorio útil para determinar la severidad de PA.

          The objective of this study was to establish the utility of c- reactive protein (CRP) as a marker of severity in patients with acute pancreatitis (AP), evaluated in the Gastroenterology service at the University Hospital of Maracaibo between March and December of 2006. Methods: This was a Prospective, descriptive and correlational study. The variables analyzed were age, sex, clinical presentation, etiology, Ranson´s criteria, Baltazar score and CRP values. CRP was determined through the quantitative technique, using the latex reagent. Results: We studied 35 patients, predominantly female 20 (57.14%), in the thirth and fourth decade of their lives. Regarding Ranson´s criteria, 25 (71.43%) presented less than 3 items, with CRP values between 8 and 128 mg/dl, 10 (28.57%) had º 3 with a CRP range between 128 and 256 mg/ dl, (p= 0.0011). A strong association between CRP and Ransom´s criteria was demonstrated (r= 0.871, p=0,0001), not observed between CRP and Balthazar score. AP of biliary etiology predominated in 16 (45.71%) The average 146,28μ80,22 CRP found in patients with alcoholic AP was higher when compared to the other etiologies. Conclusion: CRP is an useful laboratory test in order to determine the severity of AP.

          Dynamic contrast enhanced computed tomography: a precise technique for identifying and localising pancreatic necrosis.

          To evaluate dynamic contrast enhanced computed tomography for detecting and localising pancreatic necrosis in acute pancreatitis. Prospective evaluation with blind reporting of scans. Single teaching hospital. 60 Consecutive patients with acute pancreatitis suspected to have pancreatic necrosis because of major organ system failure (13); slow recovery five to seven days after admission with raised scores on the acute physiological and chronic health evaluation (APACHE-II) system (27); or findings on previous ultrasonography or computed tomography (20). Pancreatic necrosis proved histologically--that is, greater than 30 g necrotic tissue debrided at laparotomy (for life threatening sepsis or peritonitis) or necropsy. Dynamic computed tomography correctly localised pancreatic necrosis in 11 patients (confirmed at laparotomy in nine and at necropsy in two). Of nine patients with low enhancement of peripancreatic tissues alone, eight recovered after conservative management; necropsy confirmed viable pancreas and necrosis of peripancreatic fat in one patient. Of 40 patients with normal contrast enhancement, none required laparotomy to debride pancreatic necrosis. Dynamic contrast enhanced computed tomography seems to be a safe and accurate method of identifying and localising pancreatic and peripancreatic necrosis, which cannot be predicted accurately by conventional imaging techniques.

              Staging of acute pancreatitis. Is it important?

              Staging of acute pancreatitis is important for selection of patients for clinical trials, comparison of results between centers, and the early identification of patients who may benefit from therapeutic intervention or transfer to a specialist unit. The APACHE-II score and other multiple-factor scoring systems are widely used for the first two indications, and of these, the APACHE-II score provides the best accuracy at an early stage in the course of the illness. Presently, however, no system provides sufficient predictive power to facilitate clinical decision making. At a time of increasing pressure to involve specialist units at an early stage in the management of these complex patients, a pressing need to identify a system for accurate early staging of acute pancreatitis remains.
