Summary
Frameless stereotactic navigation is feasible for transanal minimally invasive surgery total mesorectal excision (TAMIS-TME). This technology may help surgeons perform safer, high-quality rectal cancer surgery.
Area of Science:
- Surgical Navigation
- Colorectal Surgery
- Oncology
Background:
- Frameless stereotaxy is established in neurosurgery and orthopedics.
- Real-time navigation has been recently applied to transanal total mesorectal excision (TAMIS-TME).
Purpose of the Study:
- To report the first pilot series on using frameless stereotactic navigation for TAMIS-TME.
- To assess the feasibility and potential benefits of this technology in rectal cancer surgery.
Main Methods:
- A pilot study involving three male patients with locally advanced rectal cancer undergoing TAMIS-TME.
- Utilized a frameless stereotactic navigational system for real-time image guidance during the transanal portion of the surgery.
Main Results:
- No intra-operative complications were recorded.
- All surgical specimens showed completely intact mesorectal envelopes with negative margins.
- Mean postoperative stay was 5 days, with no locoregional recurrence or distant metastasis at 18-month follow-up.
Conclusions:
- Frameless stereotactic navigation is feasible for TAMIS-TME.
- The technology may assist colorectal surgeons in achieving safe, high-quality outcomes in select rectal cancer cases.
