Summary

This study tests a small, portable pump that collects digestive fluids lost through a fistula or stoma and returns them to the lower intestine. The goal is to reduce the need for IV nutrition and help patients manage their condition at home. The trial will enroll 100 adults with high-output fistulas or double enterostomies.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
portable chyme reinfusion pump (Insides System device)
What this could lead to
If successful, this device could allow patients with high-output fistulas to manage their condition at home, reduce dependence on IV nutrition, and shorten hospital stays.
What could go wrong
This is a single-arm study with only 100 participants, so results may not apply to all patients. The device requires fine motor skills and cognitive ability, which may limit who can use it.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Patients with HOF (High-Output Fistulas) who are candidates for chyme reinfusion (CR) using the Insides System device will be included in the study during the pre-implantation consultation or a follow-up consultation. Patient characteristics prior to CR, as well as data related to the objectives mentioned above, will be collected both before device implantation and up to three months after intestinal reconnection
