Insights
Phonoenterography measures intestinal sounds to assess motility. This study found distinct sound patterns in patients with varying abdominal conditions, differentiating surgical outcomes.
Area of Science:
- Gastroenterology
- Medical Acoustics
- Surgical Assessment
Context:
- Intestinal motility sounds are crucial indicators of gastrointestinal function.
- Assessing post-operative intestinal activity aids in patient recovery monitoring.
- Phonoenterography offers a non-invasive method to analyze these sounds.
Purpose:
- To evaluate the utility of phonoenterography in characterizing intestinal sounds.
- To differentiate intestinal motility patterns in patients undergoing abdominal surgery.
- To correlate sound characteristics with specific abdominal pathologies and surgical outcomes.
Summary:
- The study analyzed intestinal sounds in 75 patients using phonoenterography, recording spectrograms and sonograms before and after surgery.
- An informatic program quantified sound number, intensity (dB), and frequency (Hz).
- Distinct sound profiles were observed, with higher sound counts in patients with non-digestive pathology and lower counts in peritonitis cases. Reduced sound counts correlated with lower intensity and graver tones.
Impact:
- Phonoenterography can distinguish patient-specific intestinal sound characteristics.
- The procedure provides qualitative and quantitative insights into gastrointestinal activity.
- Findings suggest potential for improved post-operative monitoring and diagnosis of abdominal conditions.
Abstract:
Our experience in using the phonoenterographic procedure in measuring the sounds produced by the intestinal motility in 75 patients is reported: 30 underwent surgery, won acute appendicitis, 20 appendicular peritonitis and 25 underwent surgery without abdominal pathology. We performed in all patients a temporary record of 3 minutes of duration, one spectrogram and one sonogram before the surgery and after surgery in the following 6, 12 and 24 hours. We obtained the number of sounds recorded by our informatic program, and also its intensity measure in dB and frequency in Hz. The procedure we have used can distinguished the characteristics of the intestinal sound of each patient and allow to show a qualitative and quantitative activity, different in the three group of patients. The number of sounds is bigger in the patients with non digestive abdominal pathology and smaller in patients with peritonitis. In general, the lesser number of sounds the lesser intensity and a more grave tones.
