Obesity surgery
-
Laparoscopic Roux-en-Y gastric bypass is one of the most commonly performed bariatric operation worldwide for the surgical management of obesity. Totally robotic Roux-en-Y gastric bypass (TR-RYGBP) has been considered to be a better approach by some groups especially early in a surgeon's experience. However, the learning curve associated with TR-RYGBP has been poorly evaluated yet. The aim of this study was to evaluate the learning curve of patients who underwent TR-RYGBP. ⋯ This study identifed criteria that should be assessed in future studies about TR-RYGBP. Both surgeon experience and bedside first assistant level affected operative duration, but surgeon experience was the most significant factor in reducing complication rates.
