title: Two-point fixed endoscopic submucosal dissection in rectal tumor (with video).
abstract: BACKGROUND
  Polypectomy, EMR, transanal endoscopic microsurgery, and surgery have been performed as treatments of rectal tumors. Endoscopic procedures are the least-invasive treatments for patients. Complete resection of the lesion is required to prevent its recurrence, and endoscopic submucosal dissection (ESD) has begun to be performed. With increasing requirements for safety, reliability, and simplicity in ESD, we decided to use a 2-point fixed ESD with a transparent hood fitted with a mucosal forceps channel in a case of a rectal tumor and report its usefulness.
  
  
  OBJECTIVE
  To evaluate the safety, simplicity, and usefulness of 2-point fixed ESD performed on a rectal tumor.
  
  
  METHODS
  Case series.
  
  
  METHODS
  Kanagawa Cancer Center Hospital.
  
  
  METHODS
  Safety, simplicity, and usefulness of 2-point fixed ESD performed on a rectal tumor.
  
  
  RESULTS
  The mean duration of the procedure was 45 minutes (range 30-110 minutes). Hemostasis and manipulation of the vessels were easy in all patients who did not have postoperative bleeding, perforation, or retroperitoneal emphysema as complications.
  
  
  CONCLUSIONS
  Uncontrolled study.
  
  
  CONCLUSIONS
  This study of 2-point ESD performed in 12 patients with rectal lesions revealed that the 2-point ESD with a transparent hood fitted with a mucosal forceps channel is a useful auxiliary device, enabling safe and reliable ESD on a rectal lesion.
