Background:

Fecal incontinence significantly impacts quality of life.
Accurate diagnosis of anal sphincter integrity is crucial for effective treatment planning.

Purpose of the Study:

To assess the clinical and functional significance of anal sphincter defects identified by ultrasound in patients with fecal incontinence.

Main Methods:

Prospective study of 100 fecal incontinence patients (1997-2001).
Utilized transanal ultrasound and vectormanometry to evaluate internal and external anal sphincter defects.
Analyzed defect extension in relation to resting and squeeze anal pressures and asymmetry index.

Main Results:

Related Experiment Videos

58% of patients exhibited anal sphincter defects; 32% had combined internal and external sphincter defects.

Combined defects were associated with significantly lower squeeze pressures and higher asymmetry indices.

A positive correlation was observed between defect radial extension and the severity of clinical complaints.

Conclusions:

Echographic identification of anal sphincter lesions is frequent in fecal incontinence.
These lesions are clinically and functionally significant, influencing patient symptoms and outcomes.
