New concept for colonoscopy including side optics and artificial intelligence

Post written by Joel Troya, MSc, from Interventional and Experimental Endoscopy (InExEn), Internal Medicine II, University Hospital Würzburg, Würzburg, Germany. The combination of artificial intelligence (AI) and side optics might help detect adenomas that otherwise could be missed. Several studies have demonstrated that the adenoma detection rate is the critical parameter for reducing the incidence …

A novel approach for weight regain after Roux-en-Y gastric bypass: Staged transoral outlet reduction (TORe) followed by surgical type 1 distalization

Post written by Omar M. Ghanem, MD, from the Department of Surgery, Mayo Clinic, Rochester, Minnesota, USA. The video describes a case of a patient suffering from weight regain after open Roux-en-Y gastric bypass (RYGB) in 2003. The patient’s presenting BMI was 59. We elected to perform a novel staged endo-laparoscopic approach with transoral outlet …

Incremental benefit of dye-based chromoendoscopy to predict the risk of submucosal invasive cancer in large nonpedunculated colorectal polyps

Post written by Mayenaaz Sidhu, MBBS, from the Department of Gastroenterology and Hepatology, Westmead Hospital, Sydney, Australia. This study was conducted to evaluate the incremental benefit of dye-based chromoendoscopy (DBC) to predict the risk of submucosal invasive cancer (SMIC) for large nonpedunculated colorectal polyps (LNPCPs) among independent observers. Real-time optical evaluation of the lesion’s surface …

Over-the-wire snare-assisted stent exchange in endoscopic retrograde cholangiopancreatography

Post written by Fateh Bazerbachi, MD, from CentraCare, Interventional Endoscopy Program, St. Cloud Hospital, St. Cloud, Minnesota, USA. Endoscopic retrograde cholangiopancreatography allows ductal stenting to alleviate symptomatic biliary or pancreatic duct strictures, and this is achieved through prosthesis placement over a guidewire. There may be a need for stent exchange during future procedures and, in …

Endoscopic submucosal dissection using traction by a spring-and-loop with clip for a laterally spreading tumor in the inferior aspect of the cecum: a nonreferral center experience

Post written by Yohei Koyama, MD, from the Department of Gastroenterology and Hepatology, Tokyo Medical University Hospital, Tokyo, Japan. Endoscopic submucosal dissection (ESD) has been widely accepted as a minimally invasive treatment for early colorectal neoplasms. However, cecal ESD remains a challenging treatment owing to the anatomical features of the cecum, such as the thin …
