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…
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…
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…
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…
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,…
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…
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…
Surveillance colonoscopy in patients with inflammatory bowel disease (IBD) with colonic involvement is recommended by multiple national and international gastrointestinal societies. Recommendations differ on the timing of initial screening colonoscopy,…
Patients with inflammatory bowel disease may develop dysplasia in the cryptal epithelium, polypoid neoplasias, and nonpolypoid (flat) adenomas, lesions at risk to proceed to colorectal carcinoma. The onset of invasion…
Much of the flat or biopsy-only detected dysplasia in inflammatory bowel disease (IBD) that had historically warranted a colectomy can now be shown to be circumscribed lesions with dye-spray or…
