Presentation Description
Institution: Nepean Hospital - NSW, Australia
Purpose
The use of robotic platforms for transanal resection (R-TAMIS) of rectal polyps and early malignancies is an increasingly utilised alternative to the conventional laparoscopic approach. Our robotic group wished to analyse surgical and oncological outcomes for our first ten R-TAMIS cases using the Da Vinci platform.
Methods
Data on consecutive R-TAMIS procedures over a 24-month period were prospectively collected and analysed. Post-operative rooms and clinic follow-up letters were also analysed to identify long-term complications.
Results
10 patients (1:1 M/F), mean age 63.5 (51- 74) and mean BMI of 32.4 (22.8 – 44.5) underwent R-TAMIS using the Da Vinci Xi device. All cases were performed using the GelPOINT Path Platform. Two R-TAMIS were successfully performed by an ANZTBCRS fellow, utilising a dual-console system. Mean console time was 141 minutes (28 - 263). Resected lesions were a mean distance of 8 cm (6 -13) from the anal verge, and a mean of 51.7cm (15 – 95) in size. Five patients were demonstrated to have at least T1 adenocarcinoma, with the remainder having dysplastic lesions. Two patients failed to have their procedures completed with R-TAMIS, due to inaccurate pre-operative MRI staging, and two underwent subsequent successful completion laparoscopic low-anterior resection (LAR). One patient was found to have a dysplastic lesion only and avoided LAR after being diagnosed with invasive malignancy on preoperative biopsy. Two patients had reported complications (urinary retention and temporary faecal incontinence), and two had delayed discharges due to mobility issues.
Conclusion
Whilst R-TAMIS appears to be a viable and safe alternative to laparoscopic TAMIS and more invasive surgery for early rectal tumours, successful outcomes depend heavily on accurate pre-operative staging and ideally MDT discussion. It appears that R-TAMIS can also be taught safely to training fellows using appropriate teaching platforms.
