Summary
Endoscopic submucosal dissection (ESD) is a feasible technique for rectal tumors, offering improved quality of life. This study shows promising resection rates and low complication rates for rectal tumor treatment.
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.
