Abstract
As a non-invasive, quantitative, and objective evaluation method, the analysis of bowel sounds has shown significant potential in clinical practice. In recent years, with the continuous advancement of signal processing techniques and analysis methods, research on bowel sounds has made significant progress. In this review, we discuss the main clinical applications of bowel sounds and summarize the commonly used analysis methods for bowel sounds at present. It is necessary to explore more comprehensive and effective signal processing technologies and methods in the future, and also establish a well-organized bowel sound database and scientific classification standards. This will promote better application of bowel sounds in clinical practice.
