Area of Science:

  • Gastroenterology
  • Surgical Oncology
  • Endoscopic Procedures

Background:

  • Endoscopic submucosal dissection (ESD) is established for gastric tumors.
  • Applying ESD to rectal tumors may enhance patient quality of life.

Purpose of the Study:

  • To evaluate the efficacy and safety of ESD for rectal tumors.
  • To assess technical feasibility, operation time, and complications.

Main Methods:

  • 35 patients with rectal tumors underwent ESD using gastric ESD techniques.
  • Efficacy, feasibility, operation time, complications, and follow-up were assessed.

Main Results:

  • One-piece resection rate was 73.3%, with 70.0% achieving tumor-free margins.

  • Median operation time was 70 minutes; perforation occurred in 2.9% of patients.
  • Recurrence-free survival was observed in 23 patients over a mean follow-up of 25.7 months.

    • Conclusions:

    • ESD is a feasible treatment for rectal tumors with promising outcomes.
    • ESD may be indicated for non-en bloc resectable rectal tumors to improve quality of life.
