Comparative study of two modes of gastroesophageal reflux measuring: conventional esophageal pH monitoring and wireless pH monitoring

Abstract: CONTEXT: Esophageal pH monitoring is considered to be the gold standard for the diagnosis of gastroesophageal acid reflux. However, this method is very troublesome and considerably limits the patient's routine activities. Wireless pH monitoring was developed to avoid these restrictions. OBJECTIVE: To compare the first 24 hours of the conventional and wireless pH monitoring, positioned 3 cm above the lower esophageal sphincter, in relation to: the occurrence of relevant technical failures, the ability t… Show more

“…The aspiration of gastric juices, the placement of a pH electrode through a gastric fistula, and the placement of an pH catheter have been used as methods for measuring gastric pH 7, 8. Previous studies have reported that the aspiration is a relatively invasive technique that may alter gastric physiology, whereas catheterization poses risks of catheter migration and substantial discomfort 1, 13. The Bravo ® pH monitoring system is a wireless radiotelemetric device used for prolonged monitoring of intraesophageal or intragastric pH that is minimally invasive and can avoid the discomforts associated with the previously mentioned methods 14…”

“…Long continuous monitoring time can reflect the status of the gastroesophagus reflux, which leads to high GERD positive detection rate, and it can effectively evaluate the frequency and severity of the reflux [55]. Comparing with traditional pH monitoring method such as catheter-based monitoring and endoscopy, it has similar diagnosis effect, but with easier and more convenient clinical operation [56,57]; also, long monitoring time of 96 h is not only effective for GERD diagnosis in the early stage, but also effective for assisting therapeutic decision in the later stage, and it evaluates the effectiveness of medical treatment.…”

“…In a prospective study comparing the catheter and capsule pH monitoring, there was no significant difference between them when used for the diagnosis of GERD; longer reflux durations were identified in the capsule pH monitoring than in the catheter pH monitoring (23). In the study by Hakanson et al (24) in which both capsule and catheter pH monitoring were simultaneously used, esophageal acid exposure time detected in capsule pH monitoring technique was approximately half of the value that was found with catheter technique (p<0.05).…”

“…Nasi et al (33) detected the prevalence of typical symptoms as 49.7% and the prevalence of atypical and/or extraesophageal symptoms as 50.3% in patients who admitted for a catheter pH monitoring. Catheter pH monitoring, when performed with a dual probe (distal and proximal esophagus), is superior to pH monitoring with single sensor capsules in patients whose main symptoms are extraesophageal or globus (23). According to Hirano et al (34), a capsule pH monitoring has the highest sensitivity in GERD monitoring compared with conventional methods (bile, pH monitoring, and MII-pH) and it is also the best tolerated method.…”
