The aim of this study was to construct an electronic bowel sound recording system and determine its usefulness for the diagnosis of appendicitis, mechanical ileus and diffuse peritonitis.
A group of 67 subjects aged 17 to 88 years including 15 controls was examined. Bowel sounds were recorded using an electret microphone placed on the right side of the hypogastrium and connected to a laptop computer. The method of adjustable grids (converted into binary matrices) was used for bowel sounds analysis.
Significantly, fewer (p ≤ 0.05) sounds were found in the mechanical ileus (1004.4) and diffuse peritonitis (466.3) groups than in the controls (2179.3). After superimposing adjustable binary matrices on combined sounds (interval between sounds <0.01 s), significant relationships (p ≤ 0.05) were found between particular positions in the matrices (row-column) and the patient groups. These included the A1_T1 and A1_T2 positions and mechanical ileus as well as the A1_T2 and A1_T4 positions and appendicitis. For diffuse peritonitis, significant positions were A5_T4 and A1_T4.
Differences were noted in the number of sounds and binary matrices in the groups of patients with acute abdominal diseases. Certain features of bowel sounds characteristic of individual abdominal diseases were indicated.
BS: bowel sound; APP: appendicitis; IL: mechanical ileus; PE: diffuse peritonitis; CG: control group; NSI: number of sound impulses; NCI: number of combined sound impulses; MBS: mean bit-similarity; TMIN: minimum time between impulses; TMAX: maximum time between impulses; TMEAN: mean time between impulses.

本研究旨在构建一种电子肠鸣音记录系统，并确定其在阑尾炎、机械性肠梗阻和弥漫性腹膜炎诊断中的实用性。
对一组年龄在17至88岁的67名受试者进行检查，其中包括15名对照者。使用置于下腹部右侧的驻极体麦克风记录肠鸣音，并将其连接到笔记本电脑上。采用可调网格法（转换为二进制矩阵）对肠鸣音进行分析。
显著地，机械性肠梗阻组（1004.4次）和弥漫性腹膜炎组（466.3次）的肠鸣音次数明显少于对照组（2179.3次）（p≤0.05）。在将可调二进制矩阵叠加到合并声音上（声音间隔<0.01秒）后，发现矩阵中的特定位置（行-列）与患者组之间存在显著关系（p≤0.05）。这些位置包括A1_T1和A1_T2位置与机械性肠梗阻，以及A1_T2和A1_T4位置与阑尾炎。对于弥漫性腹膜炎，显著位置为A5_T4和A1_T4。
在患有急性腹部疾病的患者组中，肠鸣音次数和二进制矩阵存在差异。指出了个别腹部疾病肠鸣音的某些特征。
BS：肠鸣音；APP：阑尾炎；IL：机械性肠梗阻；PE：弥漫性腹膜炎；CG：对照组；NSI：声音脉冲次数；NCI：合并声音脉冲次数；MBS：平均比特相似度；TMIN：脉冲之间的最短时间；TMAX：脉冲之间的最长时间；TMEAN：脉冲之间的平均时间。
