[Continuous extracorporeal stool transport (CEST) in a preterm infant with proximal ileostomy: report of a case].

Children with ileostomy can develop short bowel syndrome (SBS), characterized by malabsorption of nutrients and consequent malnutrition. Continuous extracorporeal stool transport (CEST) consists of collecting and transporting the intestinal effluent drained from the proximal stoma to the portion of the distal intestine. Thus, intestinal flux can be maintained, while digestion and absorption approximate real physiology until defecation.
