Dietary fiber increases stool bulk, regulates bowel transit time, and decreases intraluminal pressure. Because these actions constitute a natural way to stop diarrhea, a frequent problem with tube feedings, enteral tube feeding manufacturers have marketed several fiber-containing formulae. While bulk-forming agents such as fiber may not be appropriate for every tube-fed patient, we were unable to find any published contraindications to the use of fiber-containing enteral products. We present the case of a seriously ill man who received a fiber-containing tube feeding while also getting intestinal motility-suppressing medications. A large fiber bezoar developed, with resultant mesenteric hemorrhage. We conclude that fiber-containing tube feedings are contraindicated in certain types of patients.
膳食纤维可增加粪便体积，调节肠道运输时间，并降低肠腔内压力。由于这些作用构成了一种阻止腹泻的自然方式，而腹泻是管饲喂养中常见的问题，因此肠内管饲喂养产品制造商已推出了几种含纤维配方产品。虽然像纤维这样的容积性泻药可能并不适用于每一位接受管饲的患者，但我们未能找到任何已发表的关于使用含纤维肠内产品的禁忌症。我们报告一例重症男性患者，他在接受含纤维管饲喂养的同时还服用了抑制肠道蠕动的药物。结果形成了一个巨大的纤维性粪石，并导致肠系膜出血。我们得出结论，含纤维管饲喂养在某些类型的患者中是禁忌的。
