          Abstract

          ABSTRACT BACKGROUND: Biofeedback is an effective method of treatment for fecal incontinence but there is controversy regarding factors that may be correlated with its effectiveness. OBJECTIVE: To evaluate the efficacy of biofeedback in the treatment of fecal incontinence, identifying the predictive factors for unsuccessful treatment. METHODS: Consecutive female patients who had fecal incontinence and were treated with a full course of biofeedback were screened. The symptoms were evaluated using Cleveland Clinic incontinence (CCF) score before and six months after the completion of therapy. Patients had a satisfactory clinical response to biofeedback if the CCF score had decreased by more than 50% at six months (GI) and an unsatisfactory response if the CCF score did not decrease or if the score decreased by <50% (GII). The groups were compared with regard to age, score, anal resting and squeeze pressures and sustained squeeze pressure by manometry, history of vaginal delivery, number of vaginal deliveries, menopause, hysterectomy, and previous anorectal surgery. RESULTS: Of 124 women were included, 70 (56%) in GI and 54 (44%) in GII. The median CCF score decreased significantly from 10 to 5 (P=0.00). FI scores were higher in GII. Patients from GII had more previous vaginal deliveries and previous surgeries. The mean sustained squeeze pressure was higher in GI. Patients from GI and GII had similar ages, number of vaginal deliveries, menopause, hysterectomy, anal pressures, and sphincter defects. The median sustained squeeze pressure increased significantly before and after biofeedback in GI. CONCLUSION: Biofeedback therapy shows effective treatment with 50% reductions in FI score in half of patients. Factors associated with unsuccessful outcome include FI score ≥10, previous vaginal delivery, previous anorectal and/or colorectal surgery, and reduced mean sustained squeeze pressure.

          RESUMO CONTEXTO: Biofeedback é um método eficaz de tratamento para a incontinência fecal. No entanto, há controvérsias sobre fatores que podem ser correlacionados com a sua eficácia. Objetivo - Avaliar a eficácia do biofeedback no tratamento da incontinência fecal (IF), identificando os fatores preditivos relacionados ao insucesso do tratamento. MÉTODOS: Consecutivos pacientes do sexo feminino com IF e submetidos a terapia com biofeedback que aceitaram participar do estudo foram incluídos. Os sintomas foram avaliados utilizando o escore de incontinência da Cleveland Clinic-CCF antes e seis meses após termino da terapia. Os pacientes com resposta satisfatória ao biofeedback apresentaram redução no escore de IF ≥50% (GI) e resposta insatisfatória a redução no escore de IF <50% (GII) em seis meses. Os grupos foram comparados de acordo com a idade, escore, pressões anais quantificada pela manometria anorretal (repouso, contração e capacidade de sustentação em 30 segundos), parto vaginal prévio, número de partos vaginais, menopausa, histerectomia e cirurgia anorretal e/ou colorretal prévia. RESULTADOS: Total de 124 mulheres incluídas, 70 (56%) em GI e 54 (44%) em GII. A mediana do CCF escore reduziu significativamente de 10 para 5 (P=0.00). FI escore foi mais elevado no GII, assim como foi observado o maior número de mulheres submetidas a partos vaginais e cirurgias prévias. A pressão média de contração foi significante maior no GI. No entanto, idade, número de partos vaginais, menopausa, histerectomia, pressões anais e presença de defeito esfincteriano foram similares nos dois grupos. A pressão média de sustentação mantida por 30 seg aumentou significamente comparando pré com pós biofeedback no GI. CONCLUSÃO: O biofeedback é um tratamento eficaz com redução em 50% no escore de IF em mais da metade dos pacientes. Os fatores associados ao insucesso do tratamento incluem o escore de IF ≥10, parto vaginal prévio, cirurgia anorretal prévia e pressão média de sustentação reduzida.

          Anal-sphincter disruption during vaginal delivery.

          Lacerations of the anal sphincter or injury to sphincter innervation during childbirth are major causes of fecal incontinence, but the incidence and importance of occult sphincter damage during routine vaginal delivery are unknown. We sought to determine the incidence of damage to the anal sphincter and the relation of injury to symptoms, anorectal physiologic function, and the mode of delivery. We studied 202 consecutive women six weeks before delivery, 150 of them six weeks after delivery, and 32 with abnormal findings six months after delivery. Symptoms of anal incontinence and fecal urgency were assessed, and anal endosonography, manometry, perineometry, and measurement of the terminal motor latency of the pudendal nerves were performed. Ten of the 79 primiparous women (13 percent) and 11 of the 48 multiparous women (23 percent) who delivered vaginally had anal incontinence or fecal urgency when studied six weeks after delivery. Twenty-eight of the 79 primiparous women (35 percent) had a sphincter defect on endosonography at six weeks; the defect persisted in all 22 women studied at six months. Of the 48 multiparous women, 19 (40 percent) had a sphincter defect before delivery and 21 (44 percent) afterward. None of the 23 women who underwent cesarean section had a new sphincter defect after delivery. Eight of the 10 women who underwent forceps delivery had sphincter defects, but none of the 5 women who underwent vacuum extractions had such defects. Internal-sphincter defects were associated with a significantly lower mean (+/- SD) resting anal pressure (61 +/- 11 vs. 48 +/- 10 mm Hg, P < 0.001) six weeks post partum, and external-sphincter defects were associated with a significantly lower squeeze pressure (increase above resting pressure, 70 +/- 38 vs. 44 +/- 13 mm Hg; P < 0.001). There was a strong association (P < 0.001) between sphincter defects and the development of bowel symptoms. Occult sphincter defects are common after vaginal delivery, especially forceps delivery, and are often associated with disturbance of bowel function.

            Functional anorectal disorders.

            This report defines criteria for diagnosing functional anorectal disorders (ie, fecal incontinence, anorectal pain, and disorders of defecation). Functional fecal incontinence is defined as the uncontrolled passage of fecal material recurring for > or =3 months in an individual with a developmental age of > or =4 years that is associated with: (1) abnormal functioning of normally innervated and structurally intact muscles, and/or (2) no or minor abnormalities of sphincter structure and/or innervation insufficient to explain fecal incontinence, and/or (3) normal or disordered bowel habits (ie, fecal retention or diarrhea), and/or (4) psychological causes. However, conditions wherein structural and/or neurogenic abnormalities explain the symptom, or are part of a generalized process (eg, diabetic neuropathy) are not included within functional fecal incontinence. Functional fecal incontinence is a common, but underrecognized symptom, which is equally prevalent in men and women, and can often cause considerable distress. The clinical features are useful for guiding diagnostic testing and therapy. Functional anorectal pain syndromes include proctalgia fugax (fleeting pain) and chronic proctalgia; chronic proctalgia may be subdivided into levator ani syndrome and unspecified anorectal pain, which are defined by arbitrary clinical criteria. Functional defecation disorders are characterized by 2 or more symptoms of constipation, with > or =2 of the following features during defecation: impaired evacuation, inappropriate contraction of the pelvic floor muscles, and inadequate propulsive forces. Functional disorders of defecation may be amenable to pelvic floor retraining by biofeedback therapy (such as dyssynergic defecation).
