Post written by Michelle J. Alfa, PhD, from the St. Boniface Research Centre & University of Manitoba, Manitoba, Canada. The focus of our study was to develop a model that would mimic the accumulation of organic material and bacteria that occurs in patient-used endoscope channels when biofilm develops after repeated exposure to high-level disinfectants such …

Post written by Takemasa Hayashi, MD, from the Digestive Disease Center, Showa University Northern Yokohama Hospital, Yokohama, Japan. This study focuses on the incidence of stenosis and its relationship with the clinicopathological factors in surveillance. Endoscopic submucosal dissection for large colorectal neoplasms can reduce the need for unnecessary surgery. Large mucosal lesions should be removed …

Post written by Bruno Costa Martins, MD, from the Endoscopy Division at the Cancer Institute of the University of São Paulo. The focus of this study was to evaluate the long-term behavior of esophageal metallic stents in patients with malignant disease and palliative intent. Esophageal metallic stents are considered the mainstay palliative treatment for patients …
Post written by Toshio Kuwai, MD, from the Department of Gastroenterology, National Hospital Organization, Kure Medical Center and Chugoku Cancer Center in Hiroshima, Japan. Endoscopic submucosal dissection (ESD), although routinely performed, can prove to be challenging in areas where endoscopic mucosal resection (EMR) has already been performed because of scarring and fibrosis. A 79-year-old woman …

Post written by David S. Zimmon, MD, from the New York University School of Medicine. The author developed multiple biopsy (MB) because forceps biopsy is time consuming, creates endoscopist ergonomic stress, prolongs anesthesia, and adds excessive staff work and workplace risk from soiling, toxic fixatives and sharps. Also MB responds to demands for better patient …
Post written by Eelco C. Brand from the Department of Gastroenterology and Hepatology, University Medical Center Utrecht, Utrecht, the Netherlands. The efficacy of screening and surveillance colonoscopy is reduced by the occurrence of interval-/post-colonoscopy colorectal cancer. One of the factors associated with the occurrence of interval-/post-colonoscopy colorectal cancer is the fact that polyps and adenomas …

Post written by Hiroaki Ikematsu and Yutaka Saito from the Department of Gastroenterology, Endoscopy Division, National Cancer Center Hospital East, Kashiwa, Chiba, Japan, and National Cancer Center Hospital, Tokyo, Japan. The aim of our study was to evaluate the efficacy of blue-laser imaging (BLI) in the detectability of colorectal lesions. Most studies have not reported …
Post written by Theodore James, MD, from the University of North Carolina at Chapel Hill. We describe a case of a woman with dysphagia, found to have an esophageal duplication cyst. These are rare entities in adults and have classically required surgical resection. We describe a novel technique for endoscopic fenestration of the cyst in …
