Research: JORGE and colleagues,

JORGE and colleagues, Department of Coloproctology, University of Sao Paulo, Sao Paulo, Brazil, have reviewed (70 references) biofeedback therapy in colorectal medicine.


Biofeedback has been used for more than 20 years to treat patients with faecal incontinence, constipation, and rectal pain. It can be performed in a variety of conditions and carries minimal risk and discomfort. However it requires some degree of sphincter contraction and rectal sensitivity. It is also time-consuming and demands motivation. Mean success rates for biofeedback in the literature range from 72% for faecal incontinence, 68% for constipation, to 41% for rectal pain. However criteria for defining improvement very tremendously among researchers, and there is a tendency to prescribe biofeedback in a myriad of conditions where other options fail or are inappropriate. These factors make it difficult to compare results and emphasize the need for randomized placebo-controlled trials. In summary. Biofeedback is a cost-effective, simple, and morbidity-free technique and remains an attractive option in functional disorders of the colon, rectum, anus and pelvic floor.
