Contemporary Role of Robotics in Bariatric Surgery: Experience of CUF Infante Santo Hospital

INTRODUCTION: The use of robotics in bariatric surgery is increasing worldwide, with the main objective of reducing complications and optimising surgical outcome. This study presents a single centre 1.5-year experience and clinical outcome with robotic gastric bypass. METHODS: A retrospective review was performed of 42 consecutive patients who underwent a robotic gastric bypass. Patient files were analysed to obtain patient characteristics, weight loss results and per- and postoperative morbidity. RESULTS: In 32/42 patients, a primary gastric bypass was performed, the remaining 10 procedures were revision cases. Mean start weight was 111.1 (+/- 20.5) kg, mean start BMI was 39.7 (+/- 5.6) kg/m2. Almost half of the patients presented with pre-existing comorbidities. After a mean follow-up of 9.1 (+/-5.2) months, mean body mass index was 30.16 (+/-5.3) kg/m2 with a percentage excess weight loss of 66.16 (+/- 43.6)%. There were no conversions, no leaks and no mortality. Two patients presented with minor complications; one infected hematoma and one anastomotic ulcer. Mean length of stay in the hospital was 2.8 (2-5) days. All but one patients were satisfied with the weight loss result. CONCLUSION: The robotic gastric bypass is a safe and reproducible approach to treat morbid obesity. A secure handsewn gastrojejunal anastomosis, quick recovery and better ergonomics are the main advantages of this technique.
