Attempted Endoscopic En Bloc Resection of Mucosal and Submucosal Tumors Using Insulated-Tip Knives: A Pilot Series

Although we are convinced that methods of achieving en bloc resection of mucosal cancers and SMTs must be pursued, the insulated-tip knife in conjunction with conventional endoscopes still has limitations. Innovative endoscope design (double-channel scopes) as well as the development of new accessories will help to overcome the current limitations and further promote endoscopic tumor resection.
