Abstract
Background
The da Vinci single-port (SP) system is designed to facilitate single-incision robotic surgery in a narrow space. We developed a new procedure of rectal resection using this system. The aim of the present study was to evaluate the technical feasibility and safety of SP robotic rectal resection for rectal cancer patients based on our initial experience.
Methods
A study was conducted on consecutive patients with mid or low rectal cancer who had SP robotic resection at our institution between July and September 2020. The demographic characteristics, perioperative data, and pathology results of the patients were retrospectively analyzed.
Results
There were 5 patients (3 males, 2 females, median age 57 years (range 36–73 years). The median tumor height from the anal verge was 4 cm (range 3−5 cm). Two patients received preoperative chemoradiotherapy for advanced rectal cancer. A single docking was conducted, and the median docking time was 4 min 20 s (range 3 min 30 s to 5 min). The median total operation time was 195 min (range 155−240 min), and the median time of pelvic dissection was 45 min (range 36−62 min). All patients had circumferential and distal tumor-free resection margins. One patient experienced an anastomosis-related complication. The median duration of hospital stay was 7 days (range 7−8 days).
Conclusions
Our initial experience suggests that SP robotic rectal resection is safe and feasible. Further clinical trials comparing SP and multiport robotic rectal resection should be conducted to verify the superior aspects of this new system.
