Study of belching ability in antireflux surgery patients and normal volunteers.

The ability to belch was evaluated by a novel test, after gaseous stomach distension to standard volume, in 16 patients after antireflux surgery and nine healthy volunteers. A structured assessment of dyspeptic symptoms was also carried out in both groups. Repeat studies in volunteers showed acceptable reproducibility for the new test of belching capacity (within-subject coefficient of variance 4.5 per cent). After antireflux surgery, patients had lower volume individual belches (median(range) 27.5(0-104) ml in patients versus 76(15-165) ml in volunteers; P less than 0.02) and belched less gas within 1 h of the stimulus than volunteers (median(range) 205(0-1363) ml in patients versus 456(45-818) ml in volunteers; P less than 0.05). Belching frequency was similar in both groups. The incidence and severity of symptoms were unrelated to belched gas volumes.

Distressing belching and neuroacanthocytosis.

We report on an uncommon manifestation of molecularly proven neuroacanthocytosis in a 32-year-old man in whom dyspnea with desaturation while awake accompanied by continuous involuntary belching were the major consequences of the disease.

Off-period belching due to a reversible disturbance of oesophageal motility in Parkinson's disease and its treatment with apomorphine.

Two L-dopa-treated patients with Parkinson's disease who developed distressing belching during "off" periods are reported. In each case, contrast cine radiography revealed disturbed oesophageal motility which disappeared after injection of the dopamine receptor agonist apomorphine. It is suggested that central dopaminergic abnormalities may be important in the aetiology of "off period belching."

Pathological pharyngo-esophageal interactions.

Because of their normally coordinated function and physical contiguity, the pharynx and esophagus are subject to pathologic interactions in various disease or iatrogenic states. A useful conceptualization of these pathologic interactions is that of abnormal bolus transport. Specific clinical examples are given in which abnormal pharyngo-esophageal interactions appear to result in abnormal bolus transport, with its attendant consequences.

Role of upper esophageal reflex and belch reflex dysfunctions in noncardiac chest pain.

Fifty-four patients examined for noncardiac chest pain (NCCP), showing no esophageal motor disorder or gastroesophageal reflux disease compatible with NCCP, were subjected to an intraesophageal balloon distension test and a study of the belching reflex provoked by intraesophageal air injection. Thirty-three control subjects were also studied, allowing us to define high-threshold belchers (group I) as those who belched during two of three 40-ml distensions and low-threshold belchers (group II) as those who did not. The balloon distension test induced NCCP in 64% of the patients in group I, and in 14% of the patients in group II (P < 0.01). High-threshold belching was a factor favoring the positivity of the balloon distension test. This result supports the hypothesis that esophageal distension by air due to a belching disorder may be the mechanism responsible for NCCP in some patients with an abnormal sensitivity to balloon distension.

Upper esophageal sphincter function during belching.

We studied the mechanism of belching with specific attention to the upper esophageal sphincter (UES) in 14 normal volunteers. Belching occurred by the following sequence of events: lower esophageal sphincter relaxation; gastroesophageal gas reflux, recorded manometrically as a gastroesophageal common cavity phenomenon; UES relaxation; esophagopharyngeal gas reflux; and restoration of intraesophageal pressure to baseline by a peristaltic contraction. Upper esophageal sphincter relaxations comparable to those associated with belches were induced by abrupt esophageal distention with air boluses. In contrast, fluid boluses injected into the midesophageal body either had no effect on UES pressure or increased UES pressure. Thus, the UES responded to esophageal body distention in two distinct ways: abrupt relaxation in response to air boluses and pressure augmentation in response to fluid boluses. Mucosal anesthesia did not alter the UES response to esophageal boluses of gas or liquid thereby making it unlikely that these substances are differentiated by a mucosal receptor. Rapid distention of the proximal esophagus with a cylindrical balloon (15 cm long) elicited UES relaxation. These findings suggest that the rapidity and spatial pattern of esophageal distention, rather than discrimination of the type of material causing the distention, determines whether or not UES relaxation occurs.
