title: Endoscopic submucosal dissection by using a grasping-type scissors forceps: a preliminary clinical study (with video).
abstract: BACKGROUND
  Endoscopic submucosal dissection (ESD) with a knife is a technically demanding procedure associated with a high complication rate. The shortcoming of this method is the difficulty of fixing the knife to the target lesion. It can lead to an unexpected incision and result in major complications, such as perforation and bleeding. To reduce the risk of complications related to ESD, we developed a new grasping-type scissors forceps (GSF), which can grasp and incise the targeted tissue by using electrosurgical current.
  
  
  OBJECTIVE
  To evaluate the efficacy and safety of ESD by using GSF for the removal of gastric neoplasms in human beings.
  
  
  METHODS
  Prospective, uncontrolled, single center.
  
  
  METHODS
  Department of Gastroenterology, Aso Iizuka Hospital, Iizuka, Japan.
  
  
  METHODS
  Four patients with early gastric neoplastic lesions.
  
  
  METHODS
  After marking and injection of a solution into the submucosa, the lesion was separated from the surrounding normal mucosa by complete incision around the lesion by using the GSF. A piece of submucosal tissue was grasped and cut with the GSF by using electrosurgical current to achieve submucosal excision.
  
  
  METHODS
  Technical success and complications.
  
  
  RESULTS
  All lesions were treated easily and safely, without any unexpected incisions. No delayed hemorrhage and perforation occurred. An en bloc resection and a negative resection margin was obtained in all cases.
  
  
  CONCLUSIONS
  The small number of patients and an uncontrolled study.
  
  
  CONCLUSIONS
  ESD with GSF appeared to be an easy, safe, and technically efficient method for resecting GI neoplasms.
