An endoscopy can also be used to collect a sample of tissue (biopsy) to be tested for complications such as Barrett’s esophagus. The doctor may use tiny tweezers (forceps) in the endoscope to remove a small piece of tissue for biopsy. A biopsy viewed under a microscope can reveal damage caused by acid reflux and rule out other problems if no infecting organisms or abnormal growths are found. Upper endoscopy is more accurate than a barium swallow radiograph and may be performed in a hospital or a doctors office.
These advantages are unfortunately offset by the high cost of the pH capsule, the need of endoscopy for accurate placement, the risk of data loss during the wireless transmitting/receiving process, and the impracticality of having multiple recording sites. The elimination of the catheter, not surprisingly, has led to an improved acceptance for ambulatory pH monitoring. A study interviewing a group of patients who underwent both catheter-based and catheter-free pH monitoring reported that, if given the choice, patients certainly would prefer the wireless over the catheter-based system.
In silent reflux, stomach acid flows back up the esophagus and causes throat problems. A reflux action causes these uncomfortable sensations.

Studies in adults and children have shown that the addition of pH-MII monitoring significantly improves the physiciansâ€™ ability to diagnose reflux-related disease. In studies of infants, the use of pH-MII has been particularly important in clarifying the relationship between respiratory diseases. In the studies that she and her colleagues have conducted at the motility unit at Childrenâ€™s Hospital Boston, they found that non-acid reflux is common in pediatrics. Interestingly, even though acid reflux is more common than non-acid reflux, non-acid reflux is, in their referral population, more highly correlated with symptoms such as heartburn, chest pain, and cough than acid reflux. Chronic cough with a duration â‰¥8 weeks, and with or without acid reflux, heartburn, chest pain, and other symptoms.
Gastroesophageal reflux (GER) is the term used to describe retrograde movement of gastric contents into the esophagus. Within certain limits, this is considered to be physiological, although a physiological relevance has yet to be established. The condition is named GER disease (GERD) when patients experience symptoms or when reflux results in esophageal damage (eg, esophagitis). There is no doubt that acid is the major aggressive component of the refluxate.
This lack of response to treatment could be caused by ineffective treatment. This means that the medication is not adequately suppressing the production of acid by the stomach and is not reducing acid reflux. Alternatively, the lack of response can be explained by an incorrect diagnosis of GERD.
The axiom â€œno acid, no heartburnâ€ is not theoretically proper [9, 10]. Heartburn has been demonstrated as a cortical perception of a variety of intraesophageal events . Subjects with heartburn without erosive esophagitis represent a heterogeneous group of patients of whom some may not have gastroesophageal-reflux- (GER-) related disorder [12-15]. In clinical practice, patients with reflux symptoms and negative endoscopic findings can be classified as (1) acid-reflux-related NERD (increased acid reflux), (2) weakly acid-reflux-related NERD (weakly acid reflux with positive symptom association; hypersensitive esophagus), (3) nonacid-reflux-related NERD (nonacid reflux with positive symptom association), and (4) functional heartburn (no associations between symptoms and reflux) (Table 1) . The Rome II committee for functional esophageal disorders defined functional heartburn as an episodic retrosternal burning in the absence of pathologic GERD, pathology-based motility disorders, or structural explanations .
The infant’s proximal airway and esophagus are lined with receptors that are activated by water, acid, or distention. Activation of these receptors can increase airway resistance, leading to the development of reactive airway disease. The volume ratio of meal-stomach-esophagus differs between adults and infants. Necessary amounts of infant caloric requirements easily overwhelm gastric capacity. Reflux occurs when esophageal capacity is exceeded by refluxate.
Recognizing that in patients with multiple reflux episodes and few symptoms the association may occur by chance, other authors have advocated using, in addition to the symptom index, a symptom sensitivity index. The symptom sensitivity index is defined as the percentage of reflux episodes associated with symptoms out of the total number of reflux episodes. A symptom sensitivity index greater than 10% would further strengthen the symptom association with reflux. have shown that intraesophageal acid exposure differs based on the level at which it is measured.
EGD is a procedure in which a tube containing an optical system for visualization is swallowed. As the tube progresses down the gastrointestinal tract, the lining of the esophagus, stomach, and duodenum can be examined. Refluxed liquid that passes from the throat (pharynx) and into the larynx can enter the lungs (aspiration).
