Summary
Endoscopic submucosal dissection (ESD) effectively resects rectal carcinoid tumors, offering a minimally invasive treatment option. This technique achieves complete tumor removal with favorable outcomes, comparable to traditional surgery.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Endoscopic Procedures
Context:
- Rectal carcinoid tumors are rare neuroendocrine neoplasms.
- Traditional surgical resection can be invasive.
- Endoscopic submucosal dissection (ESD) is an emerging minimally invasive technique.
Purpose:
- To evaluate the clinical efficacy and safety of ESD for rectal carcinoid tumors.
- To assess the feasibility of complete tumor resection using ESD.
Summary:
- Five rectal carcinoid tumors (0.4-1.2 cm) were treated with ESD.
- All tumors achieved free resection margins.
- Mean procedure time was 35 minutes with minor bleeding in all cases.
- One patient experienced subserosal emphysema, recovering with conservative treatment.
- Follow-up confirmed ulcer healing without complications.
Impact:
- ESD provides a viable, organ-sparing alternative for rectal carcinoid treatment.
- This endoscopic approach achieves therapeutic effects similar to surgical operations.
- Demonstrates the potential of ESD in managing specific gastrointestinal submucosal tumors.
