The AI-powered Maestro™ platform significantly reduced operative time in laparoscopic Roux-en-Y gastric bypass (LRYGB) surgery. This innovative approach enhanced surgical efficiency and stability without compromising patient safety.

Area of Science:

Bariatric Surgery
Minimally Invasive Surgery
Surgical Technology

Background:

Laparoscopic Roux-en-Y gastric bypass (LRYGB) presents visualization and retraction challenges.
Surgical assistance variability can compound LRYGB complexity.
The Maestro™ platform is an AI-powered system for enhanced minimally invasive surgery.

Purpose of the Study:

To evaluate the impact of the Maestro™ AI surgical platform.
To compare Maestro™-assisted RYGB (MA-RYGB) with traditional LRYGB.

Main Methods:

Retrospective, matched cohort study.
Compared 54 MA-RYGB cases with 1:1 matched traditional L-RYGB cases.
Analyzed operative time, in-room time, and process stability using Statistical Process Control (SPC) charts.

Keywords:

Artificial intelligence Gastric bypass Maestro assistance Robotic surgery

Main Results:

Maestro™ reduced operative time by 19.3% (62.9 min vs. 75.1 min, p < 0.001).
MA-RYGB demonstrated more stable operative times across consecutive cases.
Postoperative outcomes and safety were comparable; no device-related complications occurred.

Conclusions:

Maestro™ significantly decreases procedure duration and improves operative course stability.
The AI platform shows potential for standardizing outcomes and operating room performance.
This technology offers improved operative quality and efficiency in bariatric surgery.
