Endoscopic ultrasound-guided fine-needle biopsy with or without macroscopic on-site evaluation: a randomized controlled noninferiority trial.

BACKGROUND : The advantage of using the macroscopic on-site evaluation (MOSE) technique during endoscopic ultrasound-guided fine-needle biopsy (EUS-FNB) performed with 22G Franseen needles has not been investigated. We aimed to compare EUS-FNB with MOSE vs. EUS-FNB performed with three needle passes.

The Role of Contrast-Enhanced Harmonic Endoscopic Ultrasound in Interventional Endoscopic Ultrasound.

Over the last decades, contrast-enhanced harmonic endoscopic ultrasound (CH-EUS) has emerged as an important diagnostic tool for the diagnosis and differentiation of several gastrointestinal diseases. The key advantage of CH-EUS is that the influx and washout of contrast in the target lesion can be observed in real time, accurately depicting microvasculature. CH-EUS is established as an evidence-based technique complementary to B-mode EUS to differentiate solid appearing structures, to characterize mass lesions, and to improve the staging of gastrointestinal and pancreatobiliary cancer.

EUS-guided gallbladder drainage in high-risk surgical patients with acute cholecystitis-procedure outcomes and evaluation of mortality predictors.

Background: Recent evidences suggest that gallbladder drainage is the treatment of choice in elderly or high-risk surgical patients with acute cholecystitis (AC). Despite better outcomes compared to other approaches, endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) is burdened by high mortality. The aim of the study was to evaluate predictive factors for mortality in high-risk surgical patients who underwent EUS-GBD for AC.

Endoscopic mucosal resection of large colonic laterally spreading tumors using a dedicated viscous solution for submucosal injection (ORISE gel): a short case series (with video).

Objective: Endoscopic mucosal resection (EMR) of large (>20 mm) laterally spreading tumors (LSTs) was usually rescheduled to guarantee experienced operator and enough endoscopic schedule time. The use of viscous solutions allows a reduction in repeated injections, snare resections and procedural time. The aim was to describe the outcome of EMR of large LSTs performed at the time of index colonoscopy, using ORISE gel (Boston Scientific).
