Role of endoscopic ultrasound and endoscopic-ultrasound-guided fine-needle aspiration in endoscopic biopsy negative gastrointestinal lesions
BACKGROUND AND OBJECTIVES Many cases of gastrointestinal (GI) tumors as lymphoma, adenocarcinoma, and most of submucosal tumors (SMT) such as gastrointestinal stromal tumor (GIST) and leiomyoma are difficult to diagnose as they frequently yield negative endoscopic biopsies. We evaluated the accuracy of endoscopic ultrasound (EUS) and EUS-guided fine-needle aspiration (EUS-FNA) in the diagnosis ...
متن کاملEndoscopic Ultrasound-Guided Fine-Needle Aspiration Vs Fine-Needle Biopsy.
RM The primary goal of fine-needle aspiration is to acquire individual cells as opposed to tissue, which is the aim of fine-needle biopsy. Cells may not necessarily provide the stroma, or the associated architecture, of the surrounding tissue. Thus, if the surrounding architecture is needed to make a diagnosis, a fine-needle biopsy, which typically uses a core biopsy needle, should provide that.
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 guided fine needle aspiration versus endoscopic ultrasound guided fine needle biopsy in sampling pancreatic masses
BACKGROUND The comparison between endoscopic ultrasound guided fine needle aspiration (EUS-FNA) and endoscopic ultrasound guided fine needle biopsy (EUS-FNB) for the diagnosis of pancreatic masses is still controversial. Many factors can affect the final results. METHODS Databases, such as PubMed, EMBASE, Cochrane Library, and Science Citation Index updated from 2000 to 2016 were searched to ...
متن کاملEndoscopic Ultrasound-Guided Fine Needle Aspiration in Cystic Pancreatic Lesions
Incidental pancreatic cysts are being increasingly recognized recently with incremented concern about health and frequent health check-up. Endoscopic ultrasound (EUS) has emerged as the principal modality for imaging pancreas for various pancreatic diseases including pancreatic cyst. But imaging alone cannot accurately identify the exact nature of the pancreatic cyst. EUS-guided fine needle asp...
