Robotic transanal total mesorectal excision for rectal cancer: experience with a first case

Abstract

BACKGROUND: A transanal approach for total mesorectal excision (TME) using a single incision port is feasible. The disadvantages are technical difficulties associated with limited manoeuvrability. METHODS: We present our first experience with robotic-assisted transanal total mesorectal excision. A 48 year-old woman with a tumour 8 cm from the anal verge was successfully operated using a transanal approach. A complete mesorectal excision was performed through a single incision port, using two robot arms. RESULTS: TME was performed successfully and the patient recovered quickly without any complications. The histological report showed a complete mesorectal excision with free distal and circumferential margins. A sigmoidoscopy showed an intact anastomosis and the patient was planned for reversal of her ileostomy. CONCLUSIONS: Transanal total mesorectal excision using the robot is feasible. Robotics may help to overcome technical difficulties associated with the single incision port.
