BACKGROUND & AIMS: Patients with aerophagia suffer from the presence of an excessive volume of intestinal gas, which is thought to result from excessive air ingestion. However, this has not been shown thus far. The aim of this study was therefore to assess swallowing and air swallowing frequencies in patients with suspected aerophagia.
Ambulatory 24-hour pH-impedance monitoring was performed in patients in whom excessive amounts of intestinal gas were visualized on plain abdominal radiograms. All patients had symptoms of bloating, abdominal distention, flatulence, or excessive belching. Reflux parameters and the number of swallows and air swallows were assessed.
The most common symptoms were bloating, abdominal distention, and constipation. Only 3 patients reported excessive belching and 1 patient reported flatulence as their predominant symptom. During the 24-hour measurement, patients showed high incidences of air swallows (521 +/- 63) and gastric belches (126 +/- 37). Patients had normal swallowing frequency (741 +/- 71).
This study presents objective parameters that confirm the existence of excessive air swallowing or aerophagia using esophageal impedance monitoring.
吞气症患者存在过量肠内气体，一般认为这是由于过度吸入空气所致。然而，目前尚无相关证据。因此，本研究旨在评估疑似吞气症患者的吞咽及吞气频率。
对腹部平片显示有过量肠内气体的患者进行24小时动态pH-阻抗监测。所有患者均有腹胀、腹部膨隆、肠胃气胀或过度嗳气症状。评估反流参数以及吞咽和吞气次数。
最常见的症状为腹胀、腹部膨隆和便秘。仅有3例患者报告以过度嗳气为主要症状，1例患者报告以肠胃气胀为主要症状。在24小时测量期间，患者吞气（521±63次）和胃嗳气（126±37次）发生率较高。患者吞咽频率正常（741±71次）。
本研究提供了客观参数，通过食管阻抗监测证实了存在过度吞气或吞气症。
