STaR centre directors Associate Professor Greg O’Grady and Professor Ian Bissett have developed a novel chyme reinfusion device.
High-output enterostomies and enteroatmospheric fistulas (EAF) are common causes of intestinal failure, and may necessitate parenteral nutrition and prolonged hospital stay. Reinfusing lost chyme into the distal gut is known to be beneficial, but implementation has been limited because manual rein-fusion is unpleasant and labour-intensive, and no devices are available.
This new purpose-built device has demonstrated benefits and acceptability in a first-in-human feasibility study. The study shows the device is effective, safe, user friendly and clinically acceptable, with the potential for to become the standard of care for high-output double enterostomies and EAFs. Pivotal trials and regulatory approvals are now in process.
