Ratification was performed based on the TNM classification as well as the Miettinen criteria. Endosonography highrisk stigmata was defined as presence of heterogeneous echopattern,cystic spaces,irregular extraluminal margin and substantial tumor (! cm). Histological malignancy was defined as mitoses on a total area of mm Final results: We identified patients with mesenchymal tumors,with immunohistochemistry confirmation of getting a GIST. There was equal distribution between genders,with a mean age of years. At diagnosis,sufferers had a synchronous tumor ( colorectal cancer). The imply size was . cm,being the spindle cell ( the most widespread Drosophilin B biological activity subtype. Stomach was probably the most frequent localization (followed by the tiny bowel. Regarding clinical presentation,in it was an incidentaloma,gastrointestinal bleeding occurred in and in ,the diagnosis was established for the duration of the management of acute abdomen. According to TNM classification, were classified as localized illness and as possessing highrisk of progression. Endoscopic ultrasound was performed in sufferers. At the initially endosonography examination,presented endosonographic highrisk stigmata,and had been refer to surgery. In all circumstances,their histological analysis revealed a low mitotic index ( mitoses on a total region of mm). Through the ecoendoscopic followup,none of your sufferers within the lowrisk group,developed highrisk attributes or metastatic disease. The mean followup was months and the median all round survival PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/21381057 at years was (localized disease: ; sophisticated disease:. Conclusion: Endoscopic ultrasound was a very good technique for following lesions with less potential for malignancy,avoiding the morbidities associated with an aggressive approach. The presence of highrisk attributes in endoscopic ultrasound,didn’t correlate using the presence of histological malignancy (elevated mitotic index). We identified a high prevalence of synchronous tumors. Our information outlines the want of new prospective studies to make and validate new ecoendoscopic functions for predicting histological malignancy.

Cho Department of Gastroenterology,Gachon University,Gil Medical Center,Incheon,Republic of KoreaContact E mail Address: imetkimgilhospital Introduction: Endoscopic ultrasound (EUS) elastography represents a new imaging process that allows quantification of tissue stiffness,with a higher degree of accuracy for the differential diagnosis of pancreatic disease. Aims Methods: The aim of this study was to evaluate the efficiency of quantitative EUS elastography for the differentiation of chronic pancreatitis (CP) and pancreatic cancer (Pc). Among August and April ,individuals with Pc,patients with CP who underwent EUS had been prospectively enrolled. EUS elastography was performed making use of linear Pentax EUS and Hitachi HI VISION Preirus. The quotient BA (strain ratio; SR) is thought of as the measure with the elastographic evaluation. Location A is representative of your pancreatic lesion strain. Area B refers to a soft peripancreatic tissue strain. The SR results had been measured in the head and physique,respectively. Results: A total of patients (mean age . years,male) have been included. The mean SR was . . for CP. . for Computer. The SR was different significantly in two groups respectively (CP vs. Computer; p). The region below the curve (AUC) of EUS elastography for diagnosing CP was . ( confiden.
