Tudies that evaluated MRCP ( participants; circumstances and participants without typical bile duct stones) had been . ( CI . to) and . ( CI . to). There was no evidence of a difference in sensitivity or specificity involving EUS and MRCP (P worth). From the incorporated research,in the median pretest probability of typical bile duct stones of the posttest probabilities (with CI) related to good and negative EUS test final results have been . ( CI . to) and . ( CI . to). In the identical pretest probability,the posttest probabilities associated with positive and damaging MRCP test results were . ( CI . to) and . ( CI . to). Conclusion: Each EUS and MRCP have high diagnostic accuracy for detection of common bile duct stones. The two tests are comparable with regards to diagnostic accuracy plus the option of which test to utilize might be informed by availability and contraindications to every test.Additional studies that happen to be of high methodological good quality are necessary to decide the diagnostic accuracy of EUS and MRCP for the diagnosis of typical bile duct stones. Disclosure of Interest: None declaredP CLINICAL Influence OF PERIAMPULLARY DIVERTICULUM AS Risk Element In the POSTERCP PANCREATITIS E. J. Kim,J. H. Yoon,H. S. Kim,C. S. Bang Gastroenterology,Hallym University Healthcare Center,Chuncheonsi,Republic of KoreaContact E mail Address: purehanmail.net Introduction: Endoscopic retrograde cholangiopancreatography (ERCP) is now the therapeutic modality for biliary too as pancreatic ailments. The correlation between PostERCP pancreatitis (PEP) and periampullary diverticulum (PAD) was evaluated in numerous research. Even so,the threat of PostERCP pancreatitis,based on the types of PAD was not elucidated. The aim of this study was to investigate threat components for postERCP pancreatitis,such as 3 forms of PAD. Aims Methods: We evaluated threat aspects for postERCP pancreatitis,based on kinds of periampullary diverticulum. This is a retrospective casecontrol study,which integrated a total of ERCPs,performed by four endoscopists in a single center. individuals with PEP,and sufferers with out PEP were enrolled. The correlation among PEP and danger aspects,such as PD,angle of prevalent bile duct (CBD),endoscopic sphincterotomy (EST),canulation time,procedure time,and 3 forms of PAD had been investigated by EMA401 supplier univariate and multivariate analyses. PAD were classified into 3 varieties by the location of ampulla of Vater: sort (n,inside the diverticulum; variety (n,on the margin of diverticulum; sort (n,outside the diverticulum. Results: In univariate evaluation,all forms of PAD,type PAD,variety PAD,type PAD had variable final results for PEP (Odd ratio , p respectively). Cannulation time and total procedure time had been substantially associated with PEP (p and respectively). Nonetheless,the angle of CBD,and EST were not which means danger factors within this study (p and respectively). Agesex adjusted multivariate evaluation showed only cannulation time as independent risk things for (OR p.) Conclusion: PAD,especially Sort PAD,cannulation time and process time have been threat factor for PEP in univariate evaluation. Nevertheless,only cannulation time was important PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/19389808 related to PEP in multivariate evaluation. While,this study had limitations of retrospective casecontrol study,prospective randomized manage study in multicenter was required. References . Lobo DN,Balfour TW,Iftikhar SY,et al.
