Ethicon’s ECHELON Powered Stapler with Gripping Surface Technology Published

Ethicon has now sponsored six, large-scale, retrospective real-world studies on clinical outcomes associated with ECHELON Powered Staplers. The research, which spans four countries and more than 41,000 patients, showed a reduction in both bleeding complications and hospital costs when ECHELON Powered Staplers are used versus other leading surgical staplers.

In the latest study, researchers found bleeding complication rates were up to 73% lower in the ECHELON Powered Stapler with GST reloads group than they were in the Signia group (0.61% vs. 2.24%).1  The complication rate associated with ECHELON Powered Staplers was below the national average for the bariatric procedure, which previous studies have shown to range from 1.16% to 4.94%.2 While bleeding complications are not common, they can be life threatening.3

The study also found median total hospital costs were approximately 7% lower for the ECHELON Powered Stapler with GST reloads group4 – although the difference was not significant for mean total hospital costs. Differences between the two stapler groups for length of stay, operating room time and all-cause inpatient readmissions within 90 days were also not statistically significant.

The study authors, which included four bariatric surgeons from around the world, used the Premier Healthcare Database of U.S. hospital discharge records to identify and analyze the real-world outcomes of 982 inpatient sleeve gastrectomy patients (491 ECHELON Powered Stapler with GST and 491 Signia System with Tri-Staple) matched for patient and hospital/provider characteristics from a pool of 5,573 patients who had the procedure between March 2017 and December 2018.

“While the study demonstrated that ECHELON Powered Stapler with GST reloads was associated with lower hemostasis related complications, further analysis is required to determine why. What we do know is stapler selection in bariatric surgery could be very important. The differences in stapler design can correlate with outcomes and complications following bariatric surgery,” said lead study author Michael “Logan” Rawlins, MD***, a bariatric surgeon with the Allegheny Health Network Bariatric & Metabolic Institute in Pittsburgh, PA.

The study authors noted, “Whereas (ECHELON) GST stabilizes and controls tissue movement through a multi-stage compression, gripping surface technology, and surgeon-controlled power; Signia with Tri-Staple has more tissue movement through a single-stage compression, a stepped cartridge and device-controlled power, thus potentially having different tissue effects intra and postoperatively.”

The ECHELON Powered Stapler with GST reloads provides a better way to staple due to its gripping surface technology, 2-stage compression and ability to handle a broad range of tissue thicknesses. The ECHELON Powered Stapler with GST reloads delivered 4-times less tissue slippage and can accommodate the broadest range of tissue thicknesses compared to Medtronic staplers.5,6 It is the only surgical stapling brand backed by large-scale, real-world, peer-reviewed evidence.7

“Ethicon is committed to improving outcomes and reducing complication rates in surgery through an evidence-based approach to elevate standard of care. Our approach encompasses understanding of the disease state, impact of surgical techniques, science of device-tissue interaction, innovative stapler design and professional education,” said Sanjoy Roy, Director, Global Health Economics and Market Access, Ethicon, Inc. and a co-author of the study.
