Post written by Jan Peveling-Oberhag, MD, from the Department of Gastroenterology, Klinikum Stuttgart, Stuttgart, Germany. The cryobiopsy technique is a new method for tissue extraction that allows for extraction of high tissue amounts with a minimal diameter endoscopic instrument. Forceps biopsies through the very small working channel of a cholangioscope are oftentimes unrepresentative. In this …

Prophylactic EUS-guided gallbladder drainage prevents acute cholecystitis in patients with malignant biliary obstruction and cystic duct orifice involvement: a randomized trial (with video)
Post written by Carlos Robles-Medranda, MD, from the Instituto Ecuatoriano de Enfermedades Digestivas, Guyaquil, Ecuador. This study focuses on the benefits of prophylactic EUS-guided gallbladder drainage (EUS-GBD) in patients with unresectable malignant biliary obstruction (MBO) and occlusion of the orifice of the cystic duct (OCD). Although acute cholecystitis (AC) will not always develop in patients with …
Fluorescence confocal microscopy for rapid evaluation of EUS fine-needle biopsy in pancreatic solid lesions
Post written by Serena Stigliano, MD, PhD, from the Therapeutic Endoscopy Department, Fondazione Policlinico Universitario Campus Bio-Medico, Rome, Italy. Fluorescence confocal laser microscopy (FCM) allows imaging of tissues in the fresh state, with minimal preparation and without any damage, distortion, or loss of tissue. We recently investigated its use in the evaluation of samples obtained with …
Closure of large mucosal defects for prevention of strictures after duodenal endoscopic submucosal dissection (with video)
Post written by Yoko Kubosawa, MD, from the Division of Gastroenterology and Hepatology, Department of Internal Medicine, and the Division of Research and Development for Minimally Invasive Treatment, Cancer Center, Keio University School of Medicine, Tokyo, Japan. We analyzed the incidence of post–endoscopic submucosal dissection (ESD) strictures after wide-field duodenal ESD. Although it is known that …
