Ethicon's Echelon Circular Powered Stapler Associated With Major Reduction In Serious Complications Following Colorectal Surgery

CINCINNATI, Aug. 11, 2021 /PRNewswire/ -- Ethicon*, part of the Johnson & Johnson Medical Devices Companies**, today announced the results of a new real-world study that shows its ECHELON CIRCULAR Powered Stapler was associated with a 74% reduction in anastomotic leak rates (1.8% vs. 6.9%)¹ and a 44% reduction in 30-day inpatient hospital readmission rates (6.1% vs.10.8%) after colorectal surgery compared with manual circular staplers.²

The study, published in Surgical Endoscopy, shows the groundbreaking device is just as effective in reducing life-threatening and costly surgical complications in real-world surgical practice as demonstrated in recent clinical studies, where the leak rate was 1.7% for the ECHELON CIRCULAR and as high as 11.8% for manual staplers.³

For the real-world study, investigators drew from data in the ECHELON CIRCULAR clinical trial (165 patients) and the Premier Healthcare database (1,348 manual circular patients) for a matching adjusted indirect comparison of patients who underwent left-sided colorectal resection.

"The data is very positive in terms of postoperative complications and intraoperative events and ease of use, specifically related to the deployment of the circular powered stapler," said study co-author Patricia Sylla, MD***, a colorectal surgeon and Associate Professor of Surgery at Mount Sinai Hospital in New York. "While anastomotic leaks are a complex problem with various contributing factors, the results of this study highlight the important role that the surgical stapler can play to reduce the potential for complications in colorectal surgery."

Each year, more than 600,000 colorectal surgical procedures are performed in the United States⁴ and despite advances in surgical technique, the incidence of anastomotic leaks remains high, occurring in nearly 12% of colorectal procedures.⁵

"The reductions in anastomotic leaks associated with the ECHELON CIRCULAR are so profound, not only in this study, but in previous ones, a closer look at stapler selection for colorectal surgery is warranted. It could lead to a change in standard surgical practice and improved patient outcomes," said Ron Landmann, MD,*** FASCRS, Section Chief of Colon and Rectal Surgery at Baptist MD Anderson Cancer Center in Jacksonville, FL, who was not involved in the study.

An anastomosis is a critical part of colorectal surgery in which two ends of the colon are connected with staples after part of the organ has been resected or removed due to damage or disease. If this connection is faulty or weak, an anastomotic leak may occur, which can lead to lengthier hospitalization, increased healthcare costs, and/or death.^6,7 Studies show the mortality rate associated with anastomotic leaks can range from 10% to 15%.⁸ The risk of death can be 3- to 15-times greater if an anastomotic leak is present.^9,10,11,12

The ECHELON CIRCULAR combines two innovative and proprietary technologies -- 3D Stapling Technology that evenly distributes compression¹³ and Gripping Surface Technology (GST) for gentler handling that reduces compressive forces on tissues.¹⁴ ECHELON CIRCULAR significantly reduced leaks at the staple line without compromising perfusion.¹⁵ 

"The results of this study well exceeded our expectations and deserve strong consideration by the surgical community," said Sanjoy Roy, Senior Director, Global Health Economics and Market Access, Ethicon, Inc. and a co-author of the latest real-world study. "The evidence, along with the innovation in design and performance, supports the possibility of this device raising the standard of care in the hands of surgeons."

ECHELON CIRCULAR is the latest addition to a clinical and real-world evidence program that includes the publication of nine peer-reviewed studies in seven countries spanning more than 60 authors and more than 46,000 patients. ECHELON Powered Staplers are the only brand of staplers back by large-scale real-world evidence in bariatric, colorectal and thoracic surgery. Click here to learn more about ECHELON CIRCULAR.
