To evaluate the preliminary outcomes of robotic surgery and present our experience in 41 rectal cancer cases. Subjects and methods: This is a prospective case series study on 41 patients who underwent robotic surgery (the da Vinci Si version) from November 2016 to July 2018 at Binh Dan Hospital. Results: There were 2 cases of anterior resection, 23 cases of low anterior resection, 6 cases of ultra-low anterior resection, 10 cases of abdominal perineal resection. Mean operation time was mins. There was no recording of intra-operative complications. Mean harvested lymph node was nodes. | Preliminary results of robotic approach in rectal cancer surgery
