Endoscopic ultrasound elastography for solid pancreatic lesions
Elastography is one of technologies assisting diagnosis of solid pancreatic lesions (SPL). This technology has been previously used for measuring the stiffness of various organs based on a principle of "harder the lesions, higher chance for malignancy". Two elastography techniques; strain and shear wave elastography, are available. For endoscopic ultrasound (EUS), only the former is existing. T...
متن کاملEndoscopic treatment of ampullary adenomas.
Tumors of the papilla of Vater are rare, with a prevalence of 0.04%±0.12% reported in autopsy studies. They may occur as sporadic lesions or in patients with familial adenomatous polyposis. Histologically, the malignant transformation of benign adenomas to carcinomas has been documented. The reported frequency of malignancy in an adenoma of the papillae ranges from 26 to 65%. Adenomatous residu...
متن کاملEndoscopic ultrasound and endoscopic ultrasound-guided fine needle aspiration in the diagnosis of diffuse gastrointestinal lesions with inconclusive endoscopic biopsies.
BACKGROUND/AIMS Many gastrointestinal tumors appearing as diffuse circumferential malignancies, for example, diffuse signet ring adenocarcinoma and lymphoma, might primarily involve the submucosal layer and hence are difficult to diagnose because they frequently yield negative endoscopic biopsies. This main aim of this study was to evaluate the accuracy of endoscopic ultrasound (EUS) and EUS-gu...
متن کاملEndoscopic ultrasound criteria to predict the need for intervention in pancreatic necrosis
BACKGROUND The natural course and treatment strategies for asymptomatic or oligosymptomatic pancreatic necrosis are still poorly defined. The aim of this retrospective study was to establish criteria for the need of intervention in patients with pancreatic necrosis. METHODS A total of 31 consecutive patients (18 male, median age 58 yrs.) diagnosed with pancreatic necrosis by endoscopic ultras...
متن کاملDoes ampullary adenoma size predict invasion on EUS? Does invasion on EUS predict presence of malignancy?
Background and study aims: It is common practice to perform ampullectomy without endoscopic ultrasound (EUS) for ampullary lesions < 1 cm but no data exists to support it. No studies have explored whether EUS findings of invasion correlate with malignancy or high-grade dysplasia (HGD) on pathology. We explored the association between adenoma size, pathology results, and invasion on EUS. Patien...
