[A speed-constant rectal lavage apparatus prepared in laboratory]
1Department of Surgery, First Affiliated Hospital of the Medical School of Zhejiang University, Hangzhou 310003,China.
Objective:
To design a speed-constant rectal lavage apparatus for assessing the rectal and anal function in liquid stool continence and the degree of fecal incontinence.
Method:
The apparatus was assembled by four common rectal lavage apparatuses, each with a container and a drainage tube.
Results:
The device could output a pulsed and speed-constant water stream with high pressure, capable of overcoming any rectal resistance change. The test for liquid continence in 12 patients with incontinence (n=12) and 12 normal control subjects (n=12) found that the retained liquid volume was significantly lower in the incontinence group than in the control group (P<0.01).
Conclusion:
Fecal incontinence could be evaluated with the speed-constant rectal lavage apparatus, which yields objective and quantitative results.
