Chyme Reinfusion for Small Bowel Double Enterostomies and Enteroatmospheric Fistulas in Adult Patients: A Systematic Review

BACKGROUND

High-output double enterostomies (DESs) and enteroatmospheric fistulas (EAFs) of the small bowel account for substantial patient morbidity and mortality. Management may include parenteral nutrition (PN) and prolonged admissions, at high cost. Reinfusion of chyme into the distal bowel is a proposed therapeutic alternative when the distal DES limb is accessible; however, standardized information on this technique is required. This review aimed to critically assess the literature regarding chyme reinfusion (CR) to define its current status and future directions.

METHODS

A systematic search of medical databases was conducted for articles investigating CR in adults. Articles reporting indications, methods, benefits, technical issues, and complications resulting from CR were reviewed. A narrative synthesis of the retrieved data was undertaken.

RESULTS

In total, 24 articles reporting 481 cases of CR were identified, although articles were heterogeneous in their structure and reporting. CR was most frequently performed for remediation of high-output DES and intestinal failure and for proximally located DES. Effluent output collection was commonly manual, with distal reinfusion more commonly automated, and with few dedicated systems. Multiple benefits attributed to CR were reported, encompassing weight gain, cessation of PN, and improvements in liver function. Technical problems included distaste, labor-intensive methods, reflux of contents, and tube dislodgement. No serious AEs or mortality directly attributable to CR were reported.

CONCLUSIONS

CR appears to be a promising, safe and well-validated intervention for small bowel DES and EAF. However, more efficient and acceptable methods are required to promote greater adoption of the practice of CR.

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.
