The design of endoscopic ultrasound (EUS) instruments has been improved to provide a wide therapeutic channel and an elevator to facilitate the movement of needles and medical devices. These im− provements make it possible to carry out combined ultrasound and endoscopic ap− proaches in the pancreas and duodenal papilla, with ultrasound examination of surrounding fluid collections [1± 5]. Cys− t...

Our aim in this study was to compare the efficiency of 25G versus 22G needles in diagnosing solid pancreatic lesions by EUS-FNA. We performed a systematic review and meta-analysis. Studies were identified in five databases using an extensive search strategy. Only randomized trials comparing 22G and 25G needles were included. The results were analyzed by fixed and random effects. A total of 504 ...

Endoscopic ultrasound (EUS) guided pseudocyst drainage can have complications such as bleeding, perforation, infection, and stent migration. We report a case of iatrogenic migration of stent inside a large dumbbell-shaped pseudocyst managed successfully with a difficult endoscopic retrieval procedure.

In this review we summarize latest data on the role of endoscopic ultrasonography (EUS) in the diagnosis and management of gastric carcinoma. Since its initial introduction in clinical practice, EUS has been considered a valuable tool for the diagnosis and locoregional staging of gastric cancer and a method of inarguable value for the assessment of gastric wall involvement and presence of infil...

Real-time elastography performed during endoscopic ultrasonography is a relatively new method for characterizing tissue stiffness, and has been used successfully as a predictor of malignancy in mediastinal lymph nodes. This case report describes our practical experience with this technique using an ultrasound bronchoscope to examine mediastinal lymph nodes. We present a case of sectorial endobr...

BACKGROUND AND STUDY AIMS Two 22G needles with similar designs, apart from the absence (A) or presence of a side port (B), are available for endoscopic ultrasound (EUS)-guided fine-needle aspiration (FNA). The side port was designed to increase diagnostic yield but this advantage was unproven. This study evaluated the difference in diagnostic yield between both needles in pancreatic masses. P...
