Biomechanical wall properties of the human rectum. A study with impedance planimetry.

Biomechanical properties of the rectal wall were studied in 17 healthy adult volunteers (nine men and eight women). With impedance planimetry it is possible to obtain simultaneous measurements of pressure and rectal cross sectional area (CSA) during balloon inflations. Rectal distensions were done with an intraluminal balloon using specified pressures up to 40 cmH2O above baseline rectal pressure.

[Prevalence and course of Wolf-Parkinson-White syndrome in a population of 138,048 subjects].
