“The Insides System is revolutionising recovery times & patient well-being.”

For the effective chyme reinfusion treatment of enterocutaneous fistulas and high-output enterostomies

Under the standard care pathway, patients recovering from colorectal surgery often have an enterostomy created to divert intestinal contents (chyme) away from the surgical site as it heals.

The enterostomy is typically left open for 6-12 months, and during this time, the chyme that is collected is disposed which can result in intestinal failure

The Insides System, is a chyme reinfusion solution, which enables diverting enterostomy, and enterocutaneous patients to reinfuse chyme back into their intestine, allowing them to recommence oral feeding and reduce length of stay in hospital.

Key Clinical Benefits of Chyme Reinfusion

Earlier return to oral feeding1

Patients able to recommence oral feeding

Improved nutritional outcome2

Increase in nutritional risk index by 10.9 (± 9.5) with a 85% reduction in intestinal losses

Improved restoration of gut function3

Limiting gut atrophy and inflammation

Improved renal function4-5

Prevents dehydration and reduces the potential for chronic kidney disease

Improved liver function5-6

53% reduction in plasma liver test abnormalities

Wean off Parenteral Nutrition6

>91% of patients weaned off parenteral nutrition within a median of 2 days (± 9)
