Rc. Dinsmore et Jf. Benson, Endoscopic removal of a knotted nasogastric tube lodged in the posterior nasopharynx, SOUTH MED J, 92(10), 1999, pp. 1005-1007
The complication of knotting nasogastric (NG) tubes on removal occurs infre
quently with small diameter feeding tubes. Knotting of large caliber NG tub
es is even more uncommon. We describe our experience in one such case, whic
h was further complicated by the inability to visualize the NG tube in the.
posterior pharynx for removal through the mouth. We also review the litera
ture and discuss risk factors.
