Swallowed gas is an important source of abdominal gas, and aerophagia is often believed as a putative cause of gas-related abdominal symptoms. However, altered gas-swallow during meals has not been demonstrated. Our aim was to characterize the number of gas swallows during meals in patients complaining of excessive belching and gaseousness and a control group without abdominal symptoms during a 24-h period.
A 24-h pH-impedance monitoring was performed in 10 patients with excessive belching, and 11 patients without digestive symptoms or reflux in the pH-impedance study. During the study, patients followed their daily routine and customary meals, without any specific limitation. In each patient the number and content of swallows and belches were analyzed.
Total meal periods were similar in controls (75±26 min) and patients (79±21 min; P=.339), but the number of gaseous swallows was greater in patients (114±13 swallows) than controls (71±8 swallows; P=.007), due to a greater frequency of gaseous swallows during meals (15±2 swallows/10 min vs 10±1 swallows/10 min, respectively; P=.008). During the 24-h study period, 66±13 belches were recorded in patients, but only 13±3 belches in controls (P<.001), mainly gastric belches (80±4% and 92±2% of belches, patients, and controls, respectively) which showed a good correlation with the number of gaseous swallows performed during meals (r=.756; P=.011).
Gas is frequently swallowed during meals. Patients complaining of excessive belching have a different swallow pattern during meals, with an increased ingestion of gas that correlates with increased gastric belching events.
吞咽气体是腹部气体的一个重要来源，人们通常认为吞气症是与气体相关的腹部症状的一个潜在原因。然而，目前尚未证明进食期间气体吞咽会发生改变。我们的目的是描述在 24 小时内抱怨过度呃逆和胃肠胀气的患者和无腹部症状的对照组在进食期间吞咽气体的次数。
对 10 例过度呃逆患者和 11 例 pH 阻抗研究中无消化症状或反流的患者进行 24 小时 pH 阻抗监测。在研究过程中，患者遵循日常惯例和日常饮食，没有任何特殊限制。在每个患者中，分析吞咽和呃逆的次数和内容。
对照组（75±26 分钟）和患者（79±21 分钟；P=.339）的总用餐时间相似，但患者的气体吞咽次数更多（114±13 次）对照组（71±8 次；P=.007），这是由于用餐期间气体吞咽的频率更高（分别为 15±2 次/10 分钟和 10±1 次/10 分钟；P=.008）。在 24 小时研究期间，记录到患者有 66±13 次呃逆，但对照组仅有 13±3 次呃逆（P<.001），主要是胃呃逆（分别为 80±4%和 92±2%的呃逆，患者和对照组）与用餐期间进行的气体吞咽次数呈良好相关性（r=.756；P=.011）。
进食期间经常吞咽气体。抱怨过度呃逆的患者在进食期间有不同的吞咽模式，摄入更多的气体，这与胃呃逆事件的增加相关。
