Reducing the Burden of Anastomotic Leaks

Anastomotic leaks are multi-factorial and still occur in up to 8.6% of cases.1*
The consequences are enormous. Leaks reduce 5-year overall survival to as little as 33.3%.2**
In addition, anastomotic leaks increase direct healthcare costs in average by approx. € 35,000 per patient, compared to treatment costs for patients without anastomotic leaks.3***

Reducing the Burden of Anastomotic Leaks

Connected Working for Tomorrow’s Care

Ethicon strives to develop the next generation of integrated treatment solutions in colorectal care to, ultimately, give patients back their tomorrows. 

We connect experienced minds and the next generation of healthcare professionals, combined with the world’s colorectal institutions and our own initiatives. Together we can establish best practices and better standards of care. 

What comes next starts now.

Early Screening

Early colorectal screening is critical to achieve a high 5-years survival rate.4 Johnson & Johnson has developed a non-branded educational campaign, which can be used to raise the importance of early screening. Further, we have entered into a partnership with the patient association Digestive Cancers Europe (DiCE).

‡Finite element-based computational simulations (FEA) on simulated porcine tissue measuring tissue compression after approximation and staple formation, comparing average standard deviation of 5.481 for 2D staples to 5.109 for 3D staples (n=37, p<0.05).

§Benchtop testing in porcine tissue ≤30mmHg (26mmHg average pressure experienced during intra-operative leak test), comparing Ethicon CDH29P to Medtronic (Covidien) manual EEA2835 (p<0.001) and preclinical perfusion model, in which perfusion was not significantly different between devices

♣Compared to conventional haemostasis using resorbable sutures or monopolar/bipolar diathermy

β Benchtop testing in 3.3mm and 4.0mm porcine tissue comparing malformed staples between ECHELON+ Stapler with GST Reloads (GST60B, GST60T) to Medtronic Signia™ Stapler with Tri-Staple™ Reloads (EGIA60AMT, SIG60AXT) and Endo GIA™ with Tri-Staple™ Reloads (EGIA60AMT, EGIA60AXT). Percentage malformed results: 1.14% vs 4.28%, p < 0.05

€In benchtop testing in porcine stomach tissue, the ECHELON+ Stapler with GST Reloads (PSEE60A, GST60T) had less mean longitudinal change in 4.0mm thick tissue, 0.79mm vs. 4.09mm, compared to the Signia™ Stapling System (SIGPHANDLE, SIG60AXT), p-value <0.05.
