[Assessment of severity of neurogenic bowel dysfunction in chronic patients with a simple 1-item questionnaire (PGI-S)]. / Sévérité des troubles colorectaux associés aux maladies neurologiques et évaluation pratique par questionnaire à un item (PGI-S).

ABSTRACT

INTRODUCTION: Bowel symptoms (constipation and incontinence) are frequent in patients with a neurologic disease, but rarely assessed in rehabilitation centres. AIM: To study the prevalence of neurogenic bowel dysfunction (NBD) in those patients, and to assess its severity with the Patient Global Impression of Severity (PGI-S). MATERIAL: Prospective study by questionnaires, with the Neurogenic Bowel Dysfunction Score (0-47) and the PGI-S, a 1-item questionnaire (absent, mild, moderate, severe) for the severity of the bowel symptoms, and the Bristol Stool Chart for stool consistency. All patients presenting a chronic (>2months) neurological disease were included. RESULTS: Inclusion of 169 patients, 97 with spinal cord injury, 42 with multiple sclerosis and 30 with hemiplegia. In each population, prevalence of constipation was 67 %, 45 % and 17 %, of pelvic floor dyssynergia 82 %, 45 % and 27 %, and leakages (gas or stools) de 74 %, 48 % and 43 %, respectively. Moderate to severe bowel symptoms were seen in 61 % of spinal cord injury, 43 % of multiple sclerosis and 23 % of hemiplegic patients, with NBD scores of 11.9±6.5, 5.7±4.9 and 3.7±4.2, respectively (P<0.01). There was a significant relation between PGI-S and NBD score (P<0.01). Significant lower NBD scores were associated with normal stool consistency (Bristol type 3 or 4) (P<0.01). In case of severe bowel symptoms, the use of transanal irrigation was hampered by patients' motivation and acceptation, and their autonomy. CONCLUSION: PGI-S and Bristol Stool Chart are reliable tools to assess the presence of bowel symptoms in clinical practice.
