Gastric ESD
Endoscopic mucosal resection (EMR) of early gastric cancer, which has been proved to be safe and effective and is the established standard of care in Japan, has become increasingly established…
Esophageal ESD
The advantage of endoscopic submucosal dissection (ESD) is the ability to achieve high R0 resection, providing low local recurrence rate. Esophageal ESD is technically more difficult than gastric ESD due…
Electrocautery for ESD
An electrical surgical unit (ESU) performs incisions and coagulation through applying Joule heat, generated by a high-frequency current onto tissue without neuromuscular stimulation. Output by the ESU includes incision output…
Endoscopic Submucosal Dissection (ESD) Versus Simplified/Hybrid ESD
The development of endoscopic submucosal dissection (ESD) has enabled en bloc resection of lesions regardless of size and shape. However, ESD of colorectal tumors is technically difficult. Early stage colorectal…
Expanding Indications for ESD
Endoscopic submucosal dissection (ESD) is useful for submucosal tumors (SMTs) within the superficial submucosal layer, but perforation frequently occurs during ESD for SMTs located at the deeper layer. Endoscopic resection…
Expanding Indications for ESD
Endoscopic resection is now considered a curative procedure for early gastric cancer. In Japan, it has increasingly replaced surgical resection for this indication, although in the West it has not…
Endoscopic Submucosal Dissection
Norio Fukami, MD, AGAF, FACG, FASGE, Editor The innovative procedure, later named endoscopic submucosal dissection (ESD), was invented in Japan in the late 1990s to address the existing limitations of…
Endoscopic Submucosal Dissection: On the Rise from East to West
Charles J. Lightdale, MD, Consulting Editor In the history of gastrointestinal endoscopy, every once in a while a new therapeutic method comes to the fore that seems difficult and risky,…
An Atlas of the Nonpolypoid Colorectal Neoplasms in Inflammatory Bowel Disease
The role of endoscopy in the management of patients with inflammatory bowel disease (IBD) is well established. However, recent data have shown significant limitations in the effectiveness of colonoscopy in…
Surgical Management of Nonpolypoid Colorectal Lesions and Strictures in Colonic Inflammatory Bowel Disease
Patients with inflammatory bowel disease (IBD) and dysplasia have pathologic characteristics and risks different from those of patients with sporadic carcinomas. Therefore, surgical interventions need to be more aggressive than…
