Abstract
This review critically evaluates the current evidence comparing robotic Roux-en-Y gastric bypass (RRYGB) and robotic sleeve gastrectomy (RSG) with their laparoscopic counterparts. Recent meta-analyses and large registry studies demonstrate broadly comparable perioperative outcomes between RRYGB and laparoscopic RYGB (LRYGB) across major clinical endpoints. Modest advantages for RRYGB have been reported in selected intraoperative and postoperative measures, including reduced anastomotic stricture rates, reduced marginal ulceration, reduced blood loss, lower conversion rates, and improved recovery in higher-risk patient groups such as in revisional surgery and high-BMI patients. However, these findings are inconsistent and largely derived from retrospective observational studies with heterogeneous methodology and limited long-term follow-up. In contrast, current evidence does not demonstrate clear clinical advantages for RSG over laparoscopic sleeve gastrectomy (LSG), and in fact may suggest inferiority in terms of short-term outcomes. Although temporal analyses suggest improvement in robotic outcomes over time, similar trends have been noted in laparoscopic cohorts, suggesting broader improvements in perioperative bariatric care. Economic analyses consistently report higher procedural costs for robotic approaches, driven primarily by operative time and consumable expenditure, although these differences may decrease with transition to totally robotic techniques, increasing institutional experience and workflow optimisation in high-volume centres.
