Implication

Randomized trial demonstrates effective resection of large rectal lesions using modified endoscopic technique, suggesting a practical solution.

Key Points

  • To assess the effectiveness of a modified double-scope endoscopic submucosal dissection technique for large rectal lesions.
  • Developed a modified dsESD technique using a thin therapeutic endoscope and an ultrathin assistant endoscope.
  • Optimized room layout for ergonomic endoscopic procedures in the anorectal space.
  • Utilized a conventional injection needle fixed to the assistant scope for efficient submucosal lifting.
  • Successful resection of an 80-mm rectal lesion completed within 70 minutes with no significant adverse events.
  • Improved visualization and hemostasis through effective three-dimensional traction and lesion elevation.
