A check-valve device for prevention of regurgitation after endoesophageal intubation
PY Wang, CY Chen and CL Chen
In pull-through endoesophageal intubation, the esophageal tube, which
traverses the esophagogastric junction, may render the sphincter function
incompetent and subsequently induce regurgitation of gastric contents
conveyed to the esophagus, reflux esophagitis, and even aspiration
pneumonia. An antireflux check-valve was developed and has been applied to
the lower end of the inserted esophageal tube in 30 patients with malignant
esophageal obstruction since September, 1982. The results have proven
satisfactory.
