RATIONALE: In ARDS, atelectatic 'solid-like' lung tissue impairs transmission of negative 'swings' in pleural pressure (Ppl) resulting from diaphragmatic contraction. The localization of more negative Ppl proportionally increases dependent lung stretch by drawing gas either from other lung regions, e.g., non-dependent lung (Pendelluft) or from the ventilator. Lowering of the level of spontaneous effort and/or converting solid-like to fluid-like lung might render spontaneous effort non-injurious...

Moo In Park
Rumination syndrome is one of the functional gastroduodenal disorders. Effortless and repetitive regurgitation of recently ingested food from the stomach to the oral cavity followed by rechewing and reswallowing or spitting are the characteristic clinical features. This disorder is believed to be uncommon, but many patients with this disorder are overlooked by their physicians. Rumination might be caused by a reversal of the gastric contents through the esophagogastric junction, which is initiated by an increase in intragastric pressure...

Yu Kyung Cho
Supragastric belching is the most important factor in the etiology of excessive belching complaints. Supragastric belching is a belching disorder with a behavioral origin. The standard diagnosis is made by monitoring the esophageal impedance. Supragastric belching has been shown to be associated with globus, as well as reflux symptoms in proton pump inhibitor non-responders in gastroesophageal reflux disease; however, the pathophysiology of supragastric belching in patients with gastroesophageal reflux disease or functional dyspepsia has not been clarified...

Background: Esophageal multichannel intraluminal impedance-pH monitoring has become one of the preferred tests to correlate observed reflux-like behaviors with esophageal reflux events. The Gastroesophageal reflux disease Assessment Symptom Questionnaire is a validated tool used to distinguish infants with gastroesophageal reflux disease from healthy children. The aim of this study was to determine whether the Gastroesophageal reflux disease Assessment Symptom Questionnaire composite symptom scores and individual symptom scores correlate with outcomes in esophageal multichannel intraluminal impedance-pH monitoring...

BACKGROUND & AIMS: It is a challenge to make a diagnosis of eosinophilic esophagitis (EoE) because its symptoms and histologic features overlap with those of gastroesophageal reflux disease (GERD). A minimally invasive device was recently developed to detect mucosal impedance (MI) that measures epithelial integrity during upper endoscopy. We aimed to quantify MI along the esophagus and identify patterns that differentiated patients with and without GERD from those with EoE, and determine whether MI values and patterns are sufficient to identify patients with EoE using histologic findings as a reference...

BACKGROUND: High-resolution impedance manometry is a technique that is well established in esophageal motility studies for relating motor patterns to bolus flow. The use of this technique in the colon has not been established. METHODS: In isolated segments of rabbit proximal colon, we recorded motor patterns and the movement of liquid or gas boluses with a high-resolution impedance manometry catheter. These detected movements were compared to video recorded changes in gut diameter...

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...
