目的：便秘通过引起腹痛和腹胀对生活质量产生负面影响。它在女性和老年人中很常见，在日本经常遇到。咖啡和苏打水的摄入促进胃肠蠕动;因此，这两种液体被认为是有效的缓解便秘。虽然需要侵入性方法或大型设备（如磁共振成像和放射摄影）来确认其对胃肠道运动的影响，但使用低成本设备可以轻松且非侵入性地进行肠鸣音（BS）评估。与咖啡不同，苏打水含有二氧化碳，因此摄入苏打水可能会增加胃肠道气体，进而影响BS的生成过程。然而，胃肠道气体和声学BS功能之间的关系尚未得到研究。本研究旨在研究苏打摄入导致的胃肠道气体增加对使用新改进的BS检测技术提取的BS声学特征的影响。方法：我们使用基于BS的声学特征，包括每分钟检测到的BS数量，BS长度和BS功率，通过基于人工神经网络的BS检测方法提取，该方法在以前的研究中开发并在此改进。结果：BS检测/分钟和BS长度显着增加后，与之前相比，咖啡和苏打水的摄入量。结论：BS长度和BS检出/min可敏感地反映胃肠动力，BS长度除反映胃肠动力外，还可反映胃肠气体信息。基于BS的声学特征记录是一种无创和方便的手段来评估功能性胃肠疾病患者的液体摄入对胃肠动力的影响。
Objective: Constipation negatively affects the quality of life by causing abdominal pain and distention. It is common among women and older individuals and frequently encountered in Japan. Coffee and soda ingestion promote gastrointestinal motility; therefore, both liquids are considered effective for alleviating constipation. While invasive approaches or large-scale equipment, such as magnetic resonance imaging and radiography, are needed to confirm their effect on gastrointestinal motility, bowel sound (BS) assessment can be easily and non-invasively performed using low-cost equipment. Differently to coffee, soda contains carbon dioxide and its ingestion may therefore increase gastrointestinal gas and in turn affect the BS generation process. However, the relationship between gastrointestinal gas and acoustic BS features has not yet been investigated. This study aimed to investigate the effect of increased gastrointestinal gas resulting from soda ingestion on the acoustic BS features extracted using a newly improved BS detection technique.Methods: We used BS-based acoustic features, including number of BSs detected/min, BS length, and BS power, extracted via an artificial neural network-based BS detection approach, which was developed in a previous study and here improved.Results: BSs detected/min and BS length significantly increased after, compared with before, coffee and soda intake. Furthermore, we found that longer BSs (>128 ms) were more significantly associated with soda (200 mL) intake than with coffee (200 mL) intake.Conclusions: BS length and BSs detected/min can sensitively evaluate gastrointestinal motility, and BS length may reflect information on gastrointestinal gas in addition to gastrointestinal motility. Recording of BS-based acoustic features is a non-invasive and convenient means to evaluate the effects of liquid intake on gastrointestinal motility in patients with functional gastrointestinal disorders.
