<strong>Abstract</strong> <em>Introduction: </em>Binh Dan hospital started to apply robotic in colorectal cancer surgery in November 2016. Our aim is to evaluate the safety of robotic surgery in management of rectal cancer. <em>Material and Methods: </em>Prospective case series study: 66 rectal cancer cases were operated by robotic da Vinci Surgical System (Si version) from November 2016 to July 2019 at Binh Dan hospital. <em>Results: </em>Men/Women ratio: 2,09. Average age: 61 yrs (23-85). Treatment: 8 cases of anterior resection, 35 cases of low anterior resection, 7 cases of ultra-low anterior resection, 16 cases of abdominal perineal resection. Post-operative pathology staging: stage I: 2 cases (3,03%), stage IIA: 9 cases (13,64%), stage IIB: 35 cases (53,03%), stage IIIB: 16 cases (24,24%), stage IIIC: 3 cases (4,55%), stage IVA: 1 case (1,51%). Intra-operative complications: one case of hemorrhage. Post-operative complications are : Surgical site infection in 12 cases, 1 case of urine retention, 1 case of ileus, 3 suspected case of anastomotic leak treatmented medially. Average length of stay after the operation is 9 days (6-16). <em>Conclusion: </em>The application of robotic surgery in rectal cancer is a safe and feasible procedure. <strong>Keyword: </strong>rectal cancer, robotic surgery. <strong>References:</strong> <ol> <li>Baek J.H., McKenzie S., Garcia-Aguilar J. and associates.
