Anal Endosonography and Incontinence

  • Abdul H. Sultan

Abstract

Anal endosonography followed modification of the rectal endoprobe (B&K Medical, Gentofte, Denmark) first described in 1982 by Frentzel-Beyme1 for imaging the prostate gland. In 1986, using the same probe, Beynon et al.2 clarified the interpretation of endosonic appearances of normal colon and rectum. For the purposes of anal endosonography, Law and Bartram modified the tip of the probe by replacing the water-filled balloon with a hard sonolucent plastic cone measuring 17 mm in diameter (Figure 14.1). The rotating endoprobe is fitted with a 7 or preferably a 10 MHz transducer (focal range 5–45 mm), which provides a 360° cross-sectional image.
