[Esophageal obstruction in tube feeding: a result of protein precipitation caused by antacids?].
A complication of tube feeding, i.e. thickening of nutrient solution in the presence of an antacid leading to obstruction of the esophagus, is reported. Three patients on artificial breathing where fed by tube with Fresubin liquid. At intervals, Alucol liquid was given for stress ulcer prevention through the tube. After 2, 4, and 50 days respectively, reflux of nutrient solution into the mouth occurred. On removal of the tube a compact, yellowish-white substance was extracted. Endoscopically, residual particles were found in the upper part of the esophagus and in the hypopharynx which obstructed the esophagus completely and in one case could only be extracted through a rigid esophagoscope. In vitro studies showed that thickening of the nutrient solution was due to interaction with antacids administered simultaneously with the nutrient.
