BACKGROUND Patients who are unable to eat or drink after stroke may receive percutaneous endoscopic gastrostomy (PEG) or nasogastric tube feeding. Although the most common serious complication is well known to be aspiration pneumonia, the role of gastroesophageal reflux (GER) has not been fully assessed. The aim of this study was to examine, by means of 24-hour esophageal pH monitoring, whether GER is related to aspiration pneumonia and whether the size and laterality of brain lesions influence GER. METHODS Sixteen stroke patients were examined using a Degitrapper pH400 (Medtronic Japan Co., Tokyo, Japan) and Zinetics 24ME multiuse pH catheter (Medtronic). All patients had stroke lesions in the territory of the left or right middle cerebral artery that were confirmed by magnetic resonance imaging (MRI) and were receiving PEG or nasogastric feeding. Stroke volume was measured with MRIcron software. RESULTS Nine patients (56%) were diagnosed with GER, and 10 (63%) developed aspiration pneumonia after enteral feeding. The rate of aspiration pneumonia was significantly higher in patients with GER (88.9%) than in those without GER (42.9%; P = .04). Patients with left hemispheric lesions had a significantly higher incidence of acid reflex than those with right lesions (116 ± 105 vs 13 ± 17; P = .04). There were no significant differences in total time of acid reflux or mean pH value between patients with left and right hemispheric lesions. The lesion volume had no significant effect on any of 3 indices of GER. CONCLUSIONS GER is associated with aspiration pneumonia and occurs more often in patients with stroke lesions in the left hemisphere.

D011237 Predictive Value of Tests In screening and diagnostic tests, the probability that a person with a positive test is a true positive (i.e., has the disease), is referred to as the predictive value of a positive test; whereas, the predictive value of a negative test is the probability that the person with a negative test does not have the disease. Predictive value is related to the sensitivity and specificity of the test.

Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM. Encephalon
