Transanal minimally invasive surgery (TAMIS) successfully resected a large 5-cm rectal gastrointestinal stromal tumor (GIST), achieving complete removal and preserving function. This approach offers a viable alternative for rectal GISTs, even beyond standard criteria.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Minimally Invasive Surgery
Background:
- Rectal gastrointestinal stromal tumors (GISTs) are rare and present surgical challenges due to location.
- Large rectal GISTs (≥5 cm) typically require complex surgical approaches due to recurrence and margin concerns.
- Standard treatment may involve neoadjuvant imatinib, but surgical resection feasibility is key.
