GI endoscopic submucosal dissection using a calibrated, small-caliber-tip, transparent hood for lesions with fibrosis

Post written by Tatsuma Nomura, MD, from the Department of Gastroenterology, Mie Prefectural Shima Hospital, Shima, and the Department of Gastroenterology, Ise Red Cross Hospital, Ise, Mie, Japan. We describe a novel technique for overcoming severe fibrosis encountered during endoscopic submucosal dissection (ESD) using a calibrated, small-caliber tip, transparent hood (CAST hood) with Pocket-creation method …

Combination of a dynamic rigidizing overtube and a novel injectable needle-type knife to facilitate colorectal endoscopic submucosal dissection

Post written by Martin Coronel, MD, and Phillip S. Ge, MD, from the Department of Gastroenterology, Hepatology and Nutrition, The University of Texas MD Anderson Cancer Center, Houston, Texas. A 66-year-old man was referred for endoscopic resection of a 35-mm laterally spreading tumor at the hepatic flexure (Paris IIa+Is). A previous EMR attempt was unsuccessful …

Evolution of re-epithelialization postcircumferential esophageal endoscopic submucosal dissection

Post written by Robert Bechara, MD, from the Queens University, Kingston Health Sciences Center, Kingston, Ontario, Canada. The introduction of endoscopic submucosal dissection (ESD) has revolutionized the management of superficial gastrointestinal neoplasia. In the esophagus, the stricture rate after a circumstantial ESD (cESD) without any prophylaxis medications is virtually 100%. There have been many reported …

Comparing a conventional and a spring-and-loop with clip traction method of endoscopic submucosal dissection for superficial gastric neoplasms

Post written by Mitsuru Nagata, MD, from the Department of Endoscopy, Shonan Fujisawa Tokushukai Hospital, Fujisawa-shi, Kanagawa, Japan. A spring-and-loop with clip (SLC; S–O clip; Zeon Medical, Tokyo, Japan) has been developed as a traction device for endoscopic submucosal dissection (ESD). Its great advantage is that it can provide traction in any direction. We hypothesized …

ESD of early-stage rectal cancer using full-time red dichromatic imaging to minimize and avoid significant bleeding

Post written by Aoi Kita, MD, and Toshio Uraoka, MD, PhD, from the Department of Gastroenterology and Hepatology, Gunma University Graduate School of Medicine, Maebashi, Japan. Red Dichromatic Imaging (RDI), a novel image-enhanced endoscopy technology (IEE), has been reported to improve the visibility of deep vessels and bleeding points compared to white-light imaging. We present …

Successful duodenal endoscopic submucosal dissection using multiple clip-and-thread traction for a large tumor located in the duodenal bulb

Post written by Tomoaki Tashima, MD, PhD, from the Department of Gastroenterology, Saitama Medical University International Medical Center, Saitama, Japan. A 74-year-old man was referred to our institute for the treatment of a large flat-elevated tumor (diameter, 50 mm) in the duodenal bulb. We selected ESD for the en bloc resection of the lesion, and the …

Evaluation of colorectal endoscopic submucosal dissection using a multifunctional snare

Post written by Jun Arimoto, MD, PhD, from the Department of Gastroenterology, Omori Red Cross Hospital, Tokyo, Japan. In this study, we evaluate the safety and efficacy of colorectal ESD using the SOUTEN snare. Although the SOUTEN snare was introduced for hybrid ESD, hybrid ESD involves partial submucosal dissection. So, we thought that “SOUTEN-ESD,” mean …

Endoscopic submucosal dissection for superficial pharyngeal carcinoma using transnasal endoscope

Post written by Daisuke Kikuchi, MD, PhD, from the Department of Gastroenterology, Toranomon Hospital, Tokyo, Japan. During endoscopic procedures, it is a great advantage that the diameter of the endoscope is small. It is possible to enter a narrow space, and it is also possible to approach a lesion that cannot be approached by the …
