Rectal neuroendocrine tumors (NETs) are rare but can be challenging to resect. Underwater endoscopic mucosal resection (EMR) offers a viable solution for complex NET cases unsuitable for standard endoscopic or surgical removal.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Endoscopic Surgery
Background:
- Rectal neuroendocrine tumors (NETs) represent a significant subset of gastrointestinal NETs.
- Standard endoscopic mucosal resection (EMR) is effective for smaller rectal NETs.
- Larger or complex rectal NETs pose resection challenges with conventional endoscopic techniques.
