Summary
Endoscopic submucosal dissection (ESD) is a promising technique for rectal neoplasia, achieving high en-bloc resection rates with minimal complications. Further development is needed, and patients should be aware of potential risks.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Endoscopic Procedures
Background:
- Endoscopic submucosal dissection (ESD) is established for gastric tumors.
- Application of ESD for rectal neoplasia is being explored for oncological benefits and improved patient quality of life.
Purpose of the Study:
- To evaluate the efficacy and safety of endoscopic submucosal dissection (ESD) for rectal neoplasia.
- To assess en-bloc resection rates, complications, and long-term outcomes of rectal ESD.
Main Methods:
- Thirty-five patients with rectal neoplasia underwent ESD using modified gastric techniques.
- Efficacy, complications, and follow-up data were systematically collected and analyzed.
Main Results:
- En-bloc resection was achieved in 88.6% of patients, with R0 resection in 62.9%.
- No blood transfusions were required; perforations occurred in 5.7% and were managed conservatively.
- Recurrence-free survival was high at 36 months, with one case of residual adenoma successfully retreated endoscopically.
Conclusions:
- Endoscopic submucosal dissection (ESD) is a feasible technique for rectal neoplasia with encouraging outcomes.
- The technique requires further refinement, and comprehensive patient counseling regarding potential risks is essential.
