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.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.Wide-field underwater EMR followed by line-assisted complete closure for a large duodenal adenoma
Duodenal adenoma has a risk of developing into cancer. En bloc resection with conventional EMR is difficult for a large lesion, whereas duodenal endoscopic submucosal dissection is associated with a high risk of perforation.1 Piecemeal underwater EMR is effective for large duodenal adenomas; however, a large mucosal defect carries a risk of delayed adverse events.2 Although complete closure after endoscopic resection can reduce adverse events,3,4 closure of a large mucosal defect with endoclips is difficult.The flat and immobile villi sign: a novel approach in identifying duodenal adenomas
The finding of duodenal polyps is rare, representing only 0.3% to 4.6% of all patients undergoing EGD.1 The prevalence of duodenal adenomas has been increasing because of the increased use of diagnostic endoscopic procedures. Duodenal adenomas are premalignant lesions leading to adenocarcinoma in 33% to 47% of cases left untreated.2-4 Historically, duodenal adenomas have been treated with radical surgical treatment because of the technical challenges associated with endoscopic resection and the high rates of recurrence.
