predictive serologic markers of AP severity, however, this characteristicremains controversial. BISAP score presents effective predictive valuesimilar to APACHE II.

Aims: Determine the value of Procalcitonin, Antithrombin III and BISAPscore as prognostic factors in early risk stratification of severe AP.

Patients &methods: Prospective study included 81 patients (16% withsevere AP). In the first 24h and 48h of admission the procalcitonin, anti-thrombin III serum concetrations and BISAP score were determined.

Results: A total of 81 patients were included (51%males) with amedianage of 64.42 years. Etiology: 60.2% biliary, 19.8% alcoholic, 2,6% post-ERCP,3.8% toxic, 1.2% autoimmune, 1.2% hereditary, 1.2% anatomic, 1.2% traumaticand 8.7% idiopathic. According to Atlanta Classification 84% were mild and16% presented severe AP. 96.1% had no complications, there were 4 deathsfrom serious systemic complications. There was correlation betweenProcalcitonin and BISAP score and the severity of AP on admission(p¼0.008 and p¼0.002, respectively). BISAP score correlated with com-plications of AP (p¼0.019 on admission and p¼0.001 at 48h). AntithrombinIII (p¼0.049) and BISAP score (p¼0.009) showed correlations with themortalility (serious systemic complications).

Conclusion: In our experience, Procalcitonin and BISAP score showedto be good early predictors of severe AP on admission and Antithrombin IIIin prediction of fatal outcome.

Introduction: Calprotectin (Cal) is a calcium-binding protein secretedpredominantly by neutrophils and monocytes. Serum Cal is thought not tobe a useful marker for early prediction of severity of pancreatitis.

Aims: To evaluate the role of serum Cal in the prediction of infectedacute necrotizing pancreatitis.

Patients & methods: Between November 2011 and December 2012patients with acute necrotizing pancreatitis admitted to our clinic wererecruited. Additionally positive controls with edematous pancreatitis andhealthy negative controls were enrolled into the study. Serum sampleswere prospectively taken for the measurement of Cal, procalcitonin (PCT),C-reactive protein (CRP) and white blood cell (WBC) count.

Results: 13 patients with acute necrotizing pancreatitis were recruited inthe study (11 male, 2 female, mean age: 50.3�18.8y). The serum Cal level onthefirst day of admission differed significantly between the groups of infectednecrosis and necrotizing acute pancreatitis (p<0.006) and between the groupof infected necrosis and acute edematous pancreatitis (p<0.03); howevertherewasno significant differencebetweennecrotizing acute pancreatitis andedematous acute pancreatitis. Analyzing the time-course changes of the in-flammatory parameters, in 70% of the cases Cal was the marker whichelevatedfirst. In 86% of the patients Cal elevationwas followed by the increasein CRP level, while WBC count and/or PCT were slightly elevated or normal.

Conclusion: Serum Cal is elevated in acute pancreatitis, but it is notable to differentiate between edematous and necrotizing pancreatitis. Caldetermination may be a useful marker to predict infected necrosis. Furthercases are needed to evaluate its role in the diagnosis.

Introduction: Acute pancreatitis is the most common major compli-cation of endoscopic retrograde cholangiopancreatography (ERCP). Itsincidence has substantial variations ranging from 5,1% to more than 25% ofall ERCP procedures. In some cases pancreatitis is followed by severecourse with pancreatic necrosis and multiorgan failure. Risk factors forpost ERCP pancreatitis (PEP) are not well established.

Aims: We aimed to correlate influence of cholestatic parameters, egtotal bilirubin, gamma-glutamyl transpeptidase (GGT), alkaline phos-phatase (AP) and liver transaminases (AST and ALT) on developmentof PEP.

Patients & methods: During 2012 at the setting of tertiary care center,we conducted prospective study that included in-patients scheduled forERCP. We recorded maximal values of above mentioned laboratory valuesbefore procedure and calculated correlation using t-test for independentsamples. All patients received diclophenac sodium suppositories imme-diately before ERCP.

Results:We included total number of 169 patients, 94 males (55%) and75 females (45%), mean age was 70.58 � 13.77 years. We observed PEP in24 out of 169 patients (14%), 13males (54.2%) and 11 females (45.8%). Meanduration of procedure was 45 � 26.00min. Mean values of bilirubin in thePEP patients was 193 � 31.22 mmol/l. We found significant positive cor-relation between level of total bilirubin, t (df¼ 2.167; 1.93) p< 0.05 andGGT t (df 2.167; 2.35) p<0.02 with occurrence of PEP. There is no corre-lation between AP and incidence of PEP, t (df 2.167; -0.106).

Conclusion: Higher values of cholestatic markers observed in patientswho developed PEPmay be independent predictor for development of PEP.

Introduction: A pancreatic pseudocyst is a collection of fluid rich inpancreatic enzymes, blood, and necrotic tissue located in the lesser sac ofthe abdomen, and is usually complications of pancreatitis. Treatment ofpancreatic pseudocysts can be obtained either by surgical or percutaneuosprocedures.

Aims: Compare patients and outcome between surgicaly and non-surgically managed patients with pancreatic pseudocysts during 3 yearperiod.

Patients &methods:During the period from 2009 to 2012, a total of 83patients were treated for pancreatic pseudocysts at First University Sur-gical Hospital, Clinical Centre of Serbia with surgical or percutaneousdrainage procedures. Theywere retrospectively reviewed and followed up.Therewere 68%men (mean age 58,3 years). Data on demographics, clinicalpresentation, pseudocyst etiology and characteristics, diagnostic evalua-tion, management and outcome were obtained.

Results: Dominating symptoms in most patients were epigastric pain,palpable mass, nausea, vomiting, fever and leukocytosis, and persistentelevation of serum amylase levels. Imaging studies, such as ultrasound,MDCT scan, MRCP and ERCP were used in establishing the diagnosis.Twenty patients were treated with percutaneous drainage procedures,with a 50% treatment failure. The rest 63 patients were treated surgicallywith internal drainage by using pseudocystojejunostomy. Patients treatedby percutaneous drainage had a higher incidence or complications (50% vs7%), a longer hospital stay (34 þ/-5days vs 11þ/-3days) and a highermorbidity rate.

Conclusion: We determined that percutaneous drainage is lessfavourable procedure with high failure rate in comparison with conven-tional surgery as it resulted in longer hospital stay, higher morbidity ratesand higher overall incidence of complications.
