Post written by Shunya Takayanagi, MD, from the Department of Gastroenterology, NTT Medical Center Tokyo, Tokyo, Japan. In this study, we reported the use of EUS-guided nasocavitary catheter drainage to treat an intra-abdominal abscess caused by delayed perforation after gastric endoscopic submucosal dissection (ESD). A 78-year-old man with early gastric cancer in the lesser curvature …
Optimal mode and power output of electrosurgical units for endoscopic papillectomy based on animal experiments and a preliminary clinical study (with videos)
Post written by Kenjiro Yamamoto, MD, from the Department of Gastroenterology and Hepatology, Tokyo Medical University, Tokyo, Japan. In this study, we conducted animal experiments to evaluate incision force and coagulation effect in various settings of the endoCUT mode with the VIO (Erbe, Tübingen, Germany) series. We determined the optimal electrosurgical unit (ESU) settings for …

Post written by Kyosuke Goda, MD, and Yusuke Hashimoto, MD, MMA, from the National Cancer Center, Hospital East Hepatobiliary Pancreatic Oncology, Chiba, Japan. A 68-year-old man with a history of diabetes mellitus was referred to our institution for evaluation of a bulky tumor in the head of the pancreas. Abdominal CT revealed a large hyperdense …
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 …

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 …
