Patients with gastroesophageal reflux disease (GERD) can present with typical or atypical symptoms. The aim of this study is to explore the underlying physiological and psychological mechanisms that lead to different symptomatic manifestations of GERD. A total of 238 patients diagnosed with GERD underwent gastroscopy, 24 h multichannel intraluminal impedance-pH (MII-pH) monitoring, and psychological assessment with questionnaires. Patient symptoms were used to classify GERD into phenotypes of typical reflux syndrome (TRS, n = 87), reflux chest pain syndrome (RCS, n = 98), and extraesophageal syndromes (EES, n = 53)...

BACKGROUND: Gastro-oesophageal reflux is very common in the paediatric age group. There is no single and reliable test to distinguish between physiologic and pathological gastro-oesophageal reflux, and this lack of clear distinction between disease and normal can have a negative impact on the management of children. AIMS: To evaluate the usefulness of 24-h oesophageal pH-impedance study in infants and children with suspected gastro-oesophageal reflux disease. METHODS: Patients were classified by age groups (A-C) and reflux-related symptoms (typical and atypical)...

A 20-year-old man was referred to our hospital with dysphagia and chest pain. Heart disease was denied. No abnormality was observed in upper esophagogastroduodenoscopy and fluoroscopy;furthermore, no gastric acid-related symptoms were observed on combined esophageal multichannel intraluminal impedance and pH monitoring. Esophageal high-resolution manometry (HRM) performed by liquid swallow revealed normal peristalsis;however, HRM performed while the patient was taking solid meals showed abnormal contraction, and the patient simultaneously complained of chest pain...

AIM: To determine whether a pH probe or multichannel intraluminal impedance (MII) more frequently detected gastro-oesophageal reflux and test the hypothesis that acid reflux was associated with lower baseline impedance. METHODS: A prospective study of infants in whom reflux was suspected and evaluated using combined pH and multichannel impedance. Studies were considered abnormal if the acid index was >10% or there were >79MII reflux events in 24 hours. The acid index was the percentage of total study time with a pH<four and the acid clearance time (ACT) the time from the pH falling below four to rising above four...

BACKGROUND: Impaired esophageal mucosal integrity plays a role in causing symptoms of gastroesophageal reflux disease (GERD). Recently, the assessment of esophageal baseline impedance (BI) using the multichannel intraluminal impedance-pH (MII-pH) test was suggested as a surrogate technique for the study of esophageal mucosal integrity and was reported to be useful in distinguishing GERD from non-GERD. However, measuring BI requires a 24-h testing period, is complicated, and causes considerable patient discomfort...

BACKGROUND: Single anastomosis gastric bypass (SaGB) was introduced in 2001 as an alternative to "loop" gastric bypass. It was considered as a procedure that would eliminate alkaline reflux and associated esophagitis. OBJECTIVES: Existing evidence about the postoperative incidence of gastroesophageal reflux (GERD) after SaGB is based on studies using symptom questionnaires. The aim of our study was to evaluate GERD 12 months after SaGB by using 24-hour multichannel intraluminal impedance pH metry (24-h MIIpH)...

Ambulatory esophageal pH monitoring is an essential method in patients exhibiting signs of non-erosive reflux disease (NERD) to make an objective diagnosis. Intra-esophageal pH monitoring is important in patients who are non-responsive to medications and in those with extraesophageal symptoms, particularly in NERD, before surgical interventions. With the help of the wireless capsule pH monitoring, measurements can be made under more physiological conditions as well as longer recordings can be performed because the investigation can be better tolerated by patients...

Globus may be a persistent symptom impairing patients' quality of life. Diagnostics and treatment are controversial but some globus patients may benefit from reassurance and attention. We investigated how globus symptoms change during a short-term follow-up without any treatment after an examination by an ear, nose and throat (ENT) physician and further diagnostic procedures. We also surveyed whether patients with persistent globus suffer from simultaneous voice problems. The study comprised 30 consecutive globus patients referred to Helsinki University Hospital, Department of Otorhinolaryngology - Head and Neck Surgery...

OBJECTIVE: Recently, a 24-h impedance was used to detect laryngopharyngeal reflux (LPR). However, not every case of LPR is pathological. Thus, pathological pharyngeal impedance values need to be clearly established to diagnose pathological LPR. The aim of our study was to establish pathological 24-h pharyngoesophageal impedance/pH values for the diagnosis of LPR. METHODS: The study was conducted in a tertiary care setting. A total of 30 patients who were referred to microlaryngoscopy for a laryngeal pathology that might be caused by LPR were included in this prospective study...
