Area of Science:

  • Gastroenterology
  • Surgical Oncology
  • Endoscopic Procedures

Background:

  • Endoscopic submucosal dissection (ESD) is a minimally invasive technique for resecting early gastrointestinal cancers.
  • Optimizing ESD procedural efficiency and outcomes remains a key focus in gastrointestinal endoscopy.
  • Tissue traction is a critical component of ESD, influencing dissection speed and safety.

Purpose of the Study:

  • To systematically review and assess the efficacy of tissue traction methods in endoscopic submucosal dissection (ESD).
  • To compare traction-assisted ESD with conventional ESD for superficial esophageal, early gastric, and colorectal neoplasms.
  • To identify factors influencing the effectiveness of traction techniques across different anatomical sites.

Main Methods:

  • Systematic electronic literature search of PubMed for comparative studies on traction-assisted versus conventional ESD.
  • Inclusion of randomized controlled trials and retrospective studies evaluating treatment outcomes.
  • Analysis of studies focusing on esophageal, gastric, and colorectal ESD procedures.

Main Results:

  • Clip line traction and submucosal tunneling reduced procedural time in esophageal ESD.
  • Gastric ESD traction efficacy varied by device, strategy, lesion location, and fibrosis.
  • Traction devices shortened colorectal ESD procedural time, especially with pocket creation.
  • Traction techniques were generally effective in facilitating ESD by maintaining adequate tissue exposure.

Conclusions:

  • Tissue traction techniques are beneficial for improving the efficiency of endoscopic submucosal dissection (ESD).
  • The efficacy of traction methods is organ- and lesion-dependent, requiring tailored approaches.
  • Further research may refine traction strategies for optimal ESD outcomes in gastrointestinal oncology.
