Utilization of methylene blue–based submucosal injection to identify residual neuroendocrine tumor in the colon after endoscopic biopsy sampling

Post written by Weina Jing, MD, and Kai Deng, MD, from the Department of Gastroenterology & Hepatology, West China Hospital, Sichuan University, Chengdu, Sichuan, China. This study provides a new way to find small residual neuroendocrine tumors. Submucosal staining assisted in the identification of minor lesions in the lamina propria of the mucosa. Neuroendocrine tumors of …

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 …
