Wide-field endoscopic mucosal resection of laterally spreading rectal tumors using a multiband ligation endoscopic mucosal resection technique
Advanced tissue resection techniques such as EMR and endoscopic submucosal dissection (ESD) have been established as therapeutic options for the management of advanced mucosal neoplasia of the colon. EMR has been found to safely and effectively remove sessile or flat neoplasms confined to the superficial layers of the GI tract.1Cold snare polypectomy in combination with a traction device for resection of a colonic adenoma partially extending into a diverticulum
Colonic diverticula lack a muscular layer because they typically develop as a result of the herniation of mucosa and submucosa through a muscle layer that the vasa recta penetrates. The herniation is caused by increased intraluminal pressure. Endoscopic resection of tumors near colonic diverticula is difficult and dangerous because of the aforementioned anatomic features. Endoscopic resection–related adverse events have been reported.1Delineating sessile serrated adenomas/polyps with acetic acid spray for a more accurate piecemeal cold snare polypectomy
Cold snare polypectomy (CSP) is becoming one of the therapeutic methods of choice for benign polyps in light of its time- and cost-effective properties compared with hot snare polypectomy.1 The safety and effectiveness of piecemeal CSP (pCSP) of large sessile serrated lesions (SSLs) have been studied in the past,2,3 and we have reported pCSP for SSLs without using injection.4 The method was effective, but minor bleeding around the edge of the SSL often rendered examination for remnant tumors more difficult.Simultaneous detection and characterization of diminutive polyps with the use of artificial intelligence during colonoscopy
The application of artificial intelligence (AI) in colonoscopy is attracting a growing amount of attention because it has the potential to improve the quality of colonoscopy.1,2 The main focuses of research in this field comprise automated polyp detection3,4 and characterization5,6 (ie, pathologic prediction), which may respectively contribute to a higher rate of adenoma detection and a reduction of the costs related to unnecessary polypectomy. However, there has not yet been any report of technology capable of simultaneous polyp detection and characterization, which is the optimal situation for fully automated colonoscopic observation.Endoscopic recognition of the sessile serrated polyp to cancer sequence
Sessile serrated polyps (SSPs), also called sessile serrated adenomas (SSAs), are the precursor lesions of 20% to 30% of colorectal cancers. The serrated polyp to cancer sequence occurs primarily in the proximal colon in the case of SSPs.
