Summary
This study shows robotic cylindrical abdominoperineal resection is a safe and feasible technique for low rectal cancer, achieving negative margins. Further research is needed to confirm its long-term efficacy.
Area of Science:
- Surgical Oncology
- Robotic Surgery
- Rectal Cancer Treatment
Background:
- The extralevator approach for abdominoperineal resection is a novel technique for low rectal cancer.
- This approach may reduce positive circumferential margins common in conventional abdominoperineal resections.
Purpose of the Study:
- To present a robotic technique for cylindrical abdominoperineal resection.
- To evaluate the safety, feasibility, and pathological adequacy of this robotic approach.
Main Methods:
- Five patients with rectal adenocarcinoma underwent robot-assisted cylindrical abdominoperineal resection.
- The daVinci robot was used for transabdominal levator muscle transection.
- Outcomes assessed included safety, feasibility, postoperative results, and specimen adequacy.
Main Results:
- The procedure was successfully completed in all 5 patients without complications or conversion to open surgery.
- Mean operative time was 343 minutes, with a mean hospital stay of 5.8 days.
- All specimens achieved an intact mesorectal envelope and negative circumferential margin, with a cylindrical shape.
Conclusions:
- Robotic assistance facilitates transabdominal levator muscle transection for cylindrical abdominoperineal resection.
- The technique demonstrated acceptable perioperative and pathological outcomes.
- Further studies are required to establish the long-term safety and efficacy of this robotic approach.
