Evaluation of the AEON Powered Stapler System in Primary Sleeve Gastrectomy:
Results of a Prospective Clinical Trial
When it comes to surgical stapling, “good enough” is simply not good enough because surgeons and their patients deserve better than bundled compromises. Achieving excellent hemostasis along the entire staple line remains the gold standard every surgeon strives for.
That standard is why we are proud to highlight the latest prospective clinical study published in the Journal of Metabolic and Bariatric Surgery.
In a prospective clinical trial, 50 consecutive primary sleeve gastrectomies performed with the AEON™ Powered Stapling System, evaluators noted excellent staple-line hemostasis, with a score of 1.04 on a 1 to 5 scale.
Evaluated 10 seconds post-firing without any buttress reinforcement material, this near-perfect hemostasis state resulted in zero bleeding interventions, zero postoperative leaks, and zero transfusions.
Outcomes like this do not happen by chance. At Lexington Medical, Inc., we listen to clinicians and strive to always keep improving. We are proud of our highly differentiated and large body of peer-reviewed clinical results.
Quotes from the Publication:
“The AEON powered stapler demonstrated excellent hemostasis, with a mean of 1.04±0.19 on a 1–5 VAS by an independent observer.”
“In our experience, hemostasis of the AEON staple line was favorable even in the absence of buttressing material or other reinforcement…”
- “There were no postoperative staple-line bleeds, leaks, reoperations, or device-related adverse events.”
Bleeding Severity Scale, showing five intraoperative images of a staple line at increasing bleeding severity: (1) no bleeding, (2) minimal bleeding, (3) moderate bleeding, (4) excessive bleeding, (5) profuse bleeding.
