TROCHEZ R., ANDREA; RINCON L., LUIS CARLOS  and  ORTIZ, RAFAEL. STUDY OF THE EFFECTIVENES OF FOUR DIFFERENT DESIGNS OF INTRALUMINAL STENTS IN ENTERIC DRAINAGE AND DECOMPRESSION. rev.fac.med [online]. 2009, vol.17, n.2, pp.207-213. ISSN 0121-5256.

Multiple surgical pediatric intestinal diseases are a real challenge for the medical team, because they compromise seriously the intestines limiting the treatment options and with it the survival options. For that reason the creativity of the surgeon in the surgical field is the resource to find an alternative that give us hope. It is like this how enteric drain stents were designed, modifying existing elements, as a solution to protect the compromised gut, help its recovery, drain its contents and stop its isquemic deterioration. Additionally they limit the formation of obstructive adhesions and the need for wide resections. The present work intends to raise its use and find common elements for the design of an ideal catheter, with optimal biophysical qualities related to the diseases to treat. With these objectives we did a hydraulic simulation of the most used drains which may serve as an excellent starting point in the design of a new product. The conclusion is that the ideal stent is not yet developed and more research like this is necessary for an optimal result, using the main characteristics of actual drains: smooth surface of pvc, softness of the silicon and the technology of the Blake's® drain in the search for a for larger surface for maximum drainage.
