S31 ENDOSCOPIC ULTRASOUND / VOLUME 6 / SUPPLEMENT 1 / AUGUST 2017 EUS-guided pancreatic pseudocyst drainage is cost-effective, feasible, realistic, and safe. DOI: 10.4103/2303-9027.212339
Gastric ectopic pancreas is an uncommon developmental anomaly and its histological diagnosis is usually difficult by using a conventional biopsy forceps. In the literature, most cases of gastric ectopic pancreas were usually diagnosed by gross pattern during endoscopic examination or features of endoscopic ultrasound. In contrast, this disease was seldom diagnosed by histology in clinical pract...
OBJECTIVES Although a large gauge needle can procure more tissue at endoscopic ultrasound-guided fine needle aspiration (EUS-FNA), its advantage over smaller needles is unclear. This study compared flexible 19G and 25G needles for EUS-FNA of solid pancreatic masses. METHODS This was a randomized trial of patients undergoing EUS-FNA of pancreatic masses using flexible 19G or 25G needle. Main o...
AIM To evaluate the diagnostic value and safety mainly regarding incidents of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) for pancreatic cystic lesions (PCLs). METHODS A total of 150 consecutive patients with suspected PCLs were prospectively enrolled from April 2015 to November 2016. We finally enrolled 140 patients undergoing EUS-FNA. We compared the diagnostic accuracy of...
BACKGROUND : Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) of the pancreas has become the preferred method for tissue diagnosis for pancreatic solid masses. The yield of EUS-FNA in this setting is influenced by multiple factors. We hypothesized that general anesthesia (GA) may improve EUS-FNA yield by improving patient cooperation and stillness during the procedure. Our objectiv...
The method of moments is used to investigate the spin dynamics of paramagnetic EuO and EuS. The theory predicts correctly those wavevectors for which a ‘spin wave’ peak appears in the spectrum. Furthermore the calculated position of this peak, when one occurs, agrees well with experiment. This suggests that earlier work, in which the same method was applied to an effective Heisenberg model for ...
Spin filtering happens due to the discriminative tunneling probabilities for spin-up and spin-down electrons through a magnetic barrier and can result in highly spin polarized tunnel currents. Combining two such barriers in a tunnel junction thus leads to large magnetoresistance without the necessity of magnetic electrodes. We demonstrate the realization of such unconventional tunnel junctions ...
BACKGROUND AND OBJECTIVES Faecal calprotectin is predictive of clinical relapse in inflammatory bowel disease and ultrasound is sensitive in detecting its post-surgical recurrence. However, no data regarding the role of calprotectin in predicting post-surgical recurrence in asymptomatic Crohn's disease are available. The aim of this study was to prospectively evaluate the role of calprotectin a...
