The Maestro\u2122 is an Artificial Intelligence (AI)-powered surgical platform designed to elevate minimally invasive surgical performance and technique while keeping the surgeon at the patient\u2019s bedside during the procedure.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective<\/jats:title>\n                    <jats:p>This study aims to assess the effects of this innovative platform by comparing it with traditional L-RYGB.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This retrospective, matched cohort study included patients who underwent Maestro\u2122 (MA-RYGB) and traditional laparoscopic Roux-en-Y gastric bypass (L-RYGB) at a single institution. The 54 Maestro\u2122-assisted RYGB procedures were included prospectively. Each case was retrospectively matched in a 1:1 ratio with a baseline laparoscopic RYGB performed by the same surgical team. Operative time, in-room time, and related variables were recorded for both groups. Statistical Process Control (SPC) charts were generated to evaluate the process stability and variability for operative times.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The Maestro\u2122 demonstrated a 19.3% reduction in operative time: MA-RYGB 62.9 min vs.75.1 min (\n                      <jats:italic>p<\/jats:italic>\n                      &lt; 0.001).
