Faecal incontinence and intractable constipation after low anterior resection (LAR) can be refractory to expectancy and appropriate anti-diarrhoea1 or laxative medications. The efficacy of anorectal biofeedback therapy (BF) in this clinical situation was prospectively
assessed. Eleven patients [5 men and 6 women; mean age 64.8 years; standard error of the mean (SEM) 3.3 years] had either faecal incontinence or intractable constipation which did not settle with medications, for at least 6 months [mean 33.3 (SEM 6.1) months] after LAR. They all underwent 4 sessions of outpatient BF. Assessment was by continence questionnaire and anorectal physiology tests, which were administered before and after BF. In 6 of 6 incontinent patients, weekly incontinent episodes were decreased [14.8 (SEA4 2.11 before, 1.8 (SEM 0.8) after; PcO.05) and anti-diarrhoea1 drug requirements were reduced (needed in 6 before, 0 after; PcO.05) after BF. In the 5 intractible constipation patients, the weekly stool frequency was improved [3 (SEM 0.5) before, 8.9 (SEM 1.6) after; P<0.05] after BF. There were no significant changes in the anorectalphysiology parameters after BF. At a mean follow-up of 12.9 (SEM 1.6) months, there were no regressions or complications. BF is a safe option for refractory bowel dysfunction following IAR.
