Usefulness of Trans-anal Ultrasonography for Anal Diseases

A comparison was made between normal and pathological anuses by ultrasonography. The following results were obtained. 1. The internal sphincter muscle could be identified by ultrasonogrephy. 2. The mean thickness of the internal sphincter was 3.6±1.4mm in normal human males and 3.1±1.0mm in females....

Summary:A comparison was made between normal and pathological anuses by ultrasonography. The following results were obtained. 1. The internal sphincter muscle could be identified by ultrasonogrephy. 2. The mean thickness of the internal sphincter was 3.6±1.4mm in normal human males and 3.1±1.0mm in females. 3. The age was not correlative to the thickness of the internal sphincter. 4. The anal resting pressure was not correlative to the thickness of the internal spincter. 5. The defect of sphincter in incontinance cases was visualized clearly by ultrasonography.
