Evaluation of an air-filled microballoon and mini-transducer in the clinical practice of anorectal manometry. Preliminary communication.

Anorectal manometry is becoming a commonly applied investigation in the field of colon and rectal surgery. Until now, however, most of this testing was performed in specialized units, which involved considerable expense and expertise to run. The authors assessed a commercially available mini-transducer and an air-filled microballoon catheter for their applicability to clinical anorectal manometry. This system is very accurate and is proving very useful in the ambulatory setting, on hospital wards, and in the operating room. It provides a simple alternative for areas where more sophisticated manometric systems are not available.
