title: Endoscopic submucosal dissection for colorectal neoplasia.
abstract: OBJECTIVE
  Endoscopic submucosal dissection (ESD) has been positively applied to and gradually standardized for early gastric cancer; however, it is not widely used in the colorectum because of its technical difficulty.
  
  
  METHODS
  To increase the safety and ease of carrying out colon ESD, we developed a new scissors-type device that we call the stag beetle knife (SBK). Here we report on our efforts to assess the efficacy and safety of colon ESD using the SBK.
  
  
  RESULTS
  ESD was carried out using SBK in 25 patients with colorectal neoplasia. All lesions were treated safety and easily, without any unexpected incisions. No delayed hemorrhage and perforation occurred. An en-bloc resection and a negative resection margin were obtained in all cases.
  
  
  CONCLUSIONS
  ESD using the SBK can be carried out with greater ease and safety for colorectal neoplasia.
