RESUMO
BACKGROUND: obstructed defecation is one of the most common subtypes of constipation, and it is frequently responsive to biofeedback treatment. AIMS: since a history of sexual and physical abuse may be present in patients with obstructed defecation, we assessed the incidence of abuse history in patients with obstructed defecation referred to a general gastroenterology practice, and whether such a history may lead to a different outcome of biofeedback training in these patients. PATIENTS AND METHODS: one hundred and twenty-one patients (17 men, 104 women, age 53 +/- 15 years) with obstructed defecation were studied by retrospective chart review. Their history of sexual, physical and psychological abuse was obtained by a standard interview, and biofeedback training was carried out by means of a three-balloon technique. RESULTS: a history of sexual/physical or psychological abuse was present in 12.4% patients. Biofeedback training yielded a successful improvement of obstructed defecation in 93% patients without abuse and in 100% of patients with abuse; this difference was not statistically different (p = 0.53). CONCLUSIONS: the prevalence of sexual/physical or psychological abuse in a population of patients with obstructed defecation referred to a general gastroenterology practice is relatively low; such a history seems not to affect the outcome of biofeedback training in these patients.
