Optimization of extra corporeal enteral prosthesis (ECEP) by selective aspiration of the digestive flow

Reinfusion is a medical process which collects digestive flow from a proximal stoma to a distal one, in patient who had a post-operative double enteral stoma. This process avoids the risk of under nutrition and frees the patient from a Total Parenteral Nutrition to offset the digestive loss. Most of the previous ways of reinfusion first collect the digestive flow into a bag before instillation. We developed an ambulatory reinfusion pump (ECEP) which had the advantage to collect the digestive flow directly from the proximal stoma and to pump it to the distal one. However, the main risk of such a continuous pumping process is to create mucosae lesions by direct suction. The aim of this study is to up-grade our device by introducing a selective aspiration based on the arrival of digestive flow.
