Given Imaging announced numerous studies confirming the value of its reflux and manometry products in diagnosing, monitoring and managing a range of gastrointestinal diseases. The studies were presented at United European Gastroenterology Week, or UEG Week. The use of impedance-pH testing showing that both acid reflux and non-acid reflux events account for persistent symptoms in PPI non-responders, especially patients with typical reflux symptoms. Authors noted that therapies beyond PPI may be necessary. Investigators concluded that among those GERD patients with insufficient treatment response, improved diagnostic yield was achieved with multichannel intraluminal impedance-wireless pH monitoring performed on PPI therapy for evaluation of non-acid reflux and off therapy for acid reflux evaluation.
