Endoscopic-mediated, biliary hydrodynamic injection mediating clinically relevant levels of gene delivery in pig liver
Post written by Robert L. Kruse, MD, PhD, from the Department of Pathology, The Johns Hopkins University School of Medicine, Baltimore, Maryland, USA. Viral-based approaches predominate the field of gene therapy for rare diseases but suffer many limitations including anti-vector immune responses and high cost of manufacturing. Our study focused on developing a novel nonviral …
Gastric neoplasms in patients with familial adenomatous polyposis: endoscopic and clinicopathologic features
Post written by Yusaku Shimamoto, MD, from the Department of Gastrointestinal Oncology, Osaka International Cancer Institute, Osaka, Japan. Gastric neoplasms in familial adenomatous polyposis (FAP) patients were classified into 4 types based on endoscopic findings. Then, their clinical, histopathologic, and genetic features were investigated. Gastric neoplasms in patients with FAP are endoscopically and histopathologically characteristic …

The use of the cap and underwater technique as an aid in endoscopic diagnosis and treatment of upper gastrointestinal bleeding
Post written by Fernando Lander Mota, MD, from the Department of Digestive Endoscopy, Hospital Sírio-Libanês, São Paulo, Brazil. Here we describe 4 cases where the use of cap and underwater technique was decisive in the management of gastrointestinal bleeding of different etiologies. The attachment of a simple transparent plastic cap allowed us to push aside …
Usefulness of a newly designed laser-cut metal stent with an anchoring hook and thin delivery system for EUS-guided hepaticogastrostomy in experimental settings
Post written by Masayuki Kitano, MD, PhD, from the Second Department of Internal Medicine, Wakayama Medical University, Wakayama, Japan. We developed a partially covered self-expandable metal stent with a thin delivery system (7.2 Fr) that has 2 advantages for EUS-guided hepaticogastrostomy (EUS-HGS). First, using a thin delivery system with a tapered tip, the stent can …
