Robotic transanal total mesorectal excision (TME) is a new surgical approach for rectal cancer. Initial results show it is feasible and safe for distal rectal cancer patients.
Area of Science:
- Minimally invasive surgery
- Colorectal surgery
- Robotic surgery
Background:
- Transanal minimally invasive surgery (TAMIS) has evolved, enabling TAMIS for total mesorectal excision (TME).
- Robotic-assisted transanal TME represents a novel advancement in rectal cancer surgery.
Observation:
- Three patients with distal rectal cancer underwent robotic transanal TME.
- The procedures were performed with curative intent by a single surgeon over 11 months.
Findings:
- All patients achieved tumor-free resection margins (distal and circumferential).
- Mesorectal resection quality was graded as I or II.
- No major morbidity or mortality was observed in the short term.
Implications:
- Robotic transanal TME is a feasible technique for en bloc rectal cancer resection.
- Further research is needed to evaluate the benefits of this innovative surgical approach.
