Are esophageal function tests helpful in symptoms suspicious of extraesophageal reflux - a prospective study in 74 patients?
The results of the present study do not support a causal link between SSEER and esophageal motility disorders, acid or non-acid reflux and EER as measured by conventional esophageal function tests and oropharyngeal pH measurement.
Our study shows that in patients with both negative KUB and urinalysis, the yield of IVU is very low and may not be necessary. This is important, as an IVU examination is not without risk. A combination of KUB with urinary analysis and careful evaluation of clinical symptoms will improve the cost-effectiveness of patient management.
