Endoscopic submucosal dissection (ESD) offers en bloc resection for gastrointestinal tumors, overcoming limitations of conventional endoscopic mucosal resection (EMR). This technique enables complete tumor removal regardless of size or location.

Area of Science:

  • Gastroenterology
  • Endoscopic Surgery
  • Oncology

Background:

  • Standard treatment for early gastrointestinal tumors is surgical resection.
  • Endoscopic resection, particularly in Japan, is accepted but limited by en bloc resection and recurrence concerns.
  • Conventional endoscopic mucosal resection (EMR) has limitations for complete lesion removal.

Purpose of the Study:

  • To introduce and detail the technique of endoscopic submucosal dissection (ESD).
  • To highlight the advantages of ESD over conventional EMR.
  • To describe the specific application and use of the Flexknife for ESD procedures.

Main Methods:

  • Development of endoscopic submucosal dissection (ESD) as an advanced endoscopic resection technique.
  • Utilization of specialized endoscopic knives including needle knife, IT knife, Hookknife, TT knife, and Flexknife.

Related Experiment Videos

  • Detailed explanation of the usage of the Flexknife, developed in cooperation with Olympus.

    • Main Results:

    • ESD enables en bloc resection of gastrointestinal lesions irrespective of size, shape, ulceration, or location.
    • Various knives are available for ESD, each with distinct advantages and disadvantages.
    • The Flexknife offers a specific approach to performing ESD procedures.

    Conclusions:

    • Endoscopic submucosal dissection (ESD) is a significant advancement in endoscopic resection for gastrointestinal tumors.
    • ESD overcomes the limitations of conventional EMR, allowing for complete tumor removal.
    • The Flexknife is a valuable tool for performing ESD, with specific techniques detailed for its use.
