Learning curves for adoption of robotic bariatric surgery: a systematic review of safety, efficiency and clinical outcomes.

Abstract

Robotic bariatric surgery may overcome challenges associated with laparoscopy, potentially achieving technically superior results. This review aims to summarise current literature reporting on learning curves for surgeons newly adopting robotic bariatrics and implications for safety, efficiency and outcomes. A systematic review was performed in line with the PRISMA guidelines. Electronic databases PubMed and MEDLINE were searched and articles reporting on learning curves in robotic bariatric surgery were identified. Studies that reported changes in outcome over time, or learning curves for surgeons newly adopting robotic bariatric surgery were included in this review. Eleven studies reporting on 1237 patients were included in this review. Most surgeons reported prior bariatric surgical experience. Differences were noted regarding the approach and adoption of robotics. Ten studies found significant reduction in operative time, with the shortest learning curve of 11 cases. Reporting of clinical outcomes was limited. Three studies reported statistically significant improvement in outcomes after the learning curve. Long-term outcomes were in line with current literature, though none assessed differences between learning curve groups. Reported learning curves in robotic bariatric surgery is variable, with limited reporting of clinical outcomes. With appropriate mentorship, surgeons can improve efficiency, safety and clinical outcomes, maximising the benefits of minimally invasive surgery.
