Abstract: Background: The catheter of the esophageal pH monitoring is associated with nasal and throat discomfort, and different behave in patients. The capsule of the wireless pH monitoring may cause chest pain and complications. Aim: To compare the wireless and conventional pH monitoring concerning the degree of discomfort and limitations in daily activities, complications, ability to diagnose pathological reflux, and costs. Methods: Twenty-five patients with symptoms of gastroesophageal reflux were prospectively… Show more

“…Another way to monitor esophageal reflux is by using a wireless sensing capsule that can achieve wireless esophageal reflux monitoring by integrated sensors. This method offers greater comfort and fewer restrictions on daily activities compared to traditional catheter-based methods. , The wireless sensing capsule is typically introduced into the gastrointestinal tract either via catheter-based delivery or swallowing accompanied by natural peristaltic waves. ,,, Nevertheless, catheter-based delivery can elicit unfavorable side effects, including throat pain, cough, and esophageal discomfort. Capsule delivery relying on natural movements can lead to incomplete or inaccurate results due to the capsule’s limited mobility, which may impede delivery to the designated area. , Moreover, the constrained mobility and rigid body of the capsule increase the chance of being entrapped within the gastrointestinal tract, leading to blockage.…”

“…It can be performed either by insertion of a transnasal catheter (which provides 24 hours of monitoring) or with a newer wireless pH-monitoring capsule (which provides 48 to 96 hours of monitoring). 2,8,9 Both monitor pH, but transnasal catheters can also measure impedance, which detects anterograde and retrograde esophageal flow and increases the likelihood of diagnosis of GERD as compared with pH monitoring alone. 9 Wireless capsule pH-monitoring may be considered in cases of transnasal catheter intolerance or when a catheter pH study is negative but GERD is highly suspected, as its longer duration may increase the likelihood of refl ux detection and cause/symptom association.…”

“…Reflux monitoring, which is performed by gastroenterologists, assesses the pH and esophageal acid exposure over a period of time and can be diagnostic of GERD; it can also correlate symptoms with reflux episodes. It can be performed either by insertion of a transnasal catheter (which provides 24 hours of monitoring) or with a newer wireless pH-monitoring capsule (which provides 48 to 96 hours of monitoring) 2,8,9. Both monitor pH, but transnasal catheters can also measure impedance, which detects anterograde and retrograde esophageal flow and increases the likelihood of diagnosis of GERD as compared with pH monitoring alone 9.…”
