En bloc endoscopic submucosal dissection of a 14-cm laterally spreading adenoma of the rectum with involvement to the anal canal: expanding the frontiers of endoscopic surgery (with video)

Clinical outcome of endoscopic submucosal dissection versus endoscopic mucosal resection of large colorectal tumors as determined by curative resection

“…However, conventional EMR techniques [6][7][8] currently used for the resection of laterally spreading tumors (LSTs) [7][8][9][10] are inadequate for the en bloc resection of flat lesions C20 mm because of both incomplete removal [11] and problems with local recurrence [12]. The endoscopic submucosal dissection (ESD) technique, which facilitates en bloc resection of early gastric cancer [11,[13][14][15][16][17], has recently been reported to be useful in the treatment of superficial colorectal tumors [18][19][20][21][22][23][24][25][26][27][28]. Previously, we reported on the effectiveness and safety of ESD for colorectal tumors using a bipolar needle knife (B-knife) (XEMEX Co., Tokyo, Japan) and an insulation-tipped knife (IT knife) (Olympus Optical Co., Ltd., Tokyo, Japan), neither of which produces any coagulation effect at the needle tip [20,21,24].…”

Nodal metastasis after successful endoscopic submucosal dissection for colorectal mucosal cancer

“…3). ESD is now being increasingly used worldwide for the treatment of colorectal mucosal cancer [4] because en bloc resection of a lesion is possible regardless of lesion size. In the present case, ESD was appropriate treatment for both lesions according to the histologic curative criteria [3], and the lesions appeared to have been successfully treated.…”

Clinical Impact of Endoscopic Devices for Colorectal Endoscopic Submucosal Dissection

“…perforation) have been reported [3,4]. ESD, which facilitates en bloc resection of early gastric cancer, has recently been reported to be useful for the treatment of superficial colorectal tumors [10,11,12,13,14,15,16,17,18]. Following the introduction of an insulation-tipped diathermic knife (IT knife), many other devices have been reported for ESD [6,7,8].…”

“…perforation and bleeding). More recently, owing to the availability of several knives [5,6,7,8], the effectiveness of colorectal ESD has been reported [9,10,11,12,13,14,15,16,17,18]. However, there have been no reports concerning differences in usage between monopolar knives and bipolar knives in colorectal ESD.…”
