Wide-field underwater EMR followed by line-assisted complete closure for a large duodenal adenoma

Post written by Hiroko Nakahira, MD, from the Department of Gastrointestinal Oncology, Osaka International Cancer Institute, Osaka, Japan. Underwater endoscopic mucosal resection (EMR) was performed for a large duodenal adenoma in a patient with familial adenomatous polyposis, and the mucosal defect after underwater EMR was closed with line-assisted complete closure technique. Endoscopic mucosal resection for …

The role of oral simethicone on the adenoma detection rate and other quality indicators of screening colonoscopy

Post written by Antonio Mendoza Ladd, MD, from the Division of Gastroenterology, Texas Tech University Health Sciences Center, El Paso, Texas, USA. The primary aim of this study was determining if adding simethicone (SIM) to 4 L polyethylenglycol (PEG) preparation improved our ADR. Secondary aims included its effect on procedure times, Bubble and Boston Bowel …

Increasing adenoma detection rates in the right side of the colon

Post written by Madhav Desai, MD, MPH, from the Gastroenterology and Hepatology, University of Kansas Medical Center, Kansas City, Kansas, USA. Colonoscopy prevents colon cancer and, therefore, has become a widely used screening modality. Right-sided lesions are often missed during standard colonoscopy and could account for interval colon cancer. As gastroenterologists and endoscopists, our keen …

Adenoma recurrence after piecemeal colonic EMR is predictable

Post written by David J. Tate, MA (Cantab), MBBS, MRCP, from Westmead Hospital, Department of Gastroenterology and Hepatology, and Westmead Campus, University of Sydney Medical School, Sydney, Australia. Recurrence is the main limitation of wide-field endoscopic mucosal resection (EMR) for large laterally spreading colonic lesions (LSL). We aimed to derive a set of clinically useful …

ADR varies during colonoscopy training

Sascha C. van Doorn, MD, from the Department of Gastroenterology and Hepatology at the Academic Medical Centre at the University of Amsterdam in Amsterdam, the Netherlands discusses this Original Article "Adenoma detection rate varies greatly during colonoscopy training." During endoscopy training of gastroenterology fellows (GI-fellows), the most important competency for colonoscopy is safe cecal intubation. …
