Outcome Of Transanal Irrigation For Bowel Dysfunction 1N Patients With Spinal Cord Injury

Abstract

Background/Objective: To compare symptoms of neurogenic bowel dysfunction in patients with spinal cord injury (SCI) at baseline and after 10 weeks of treatment with transanal irrigation and to identify possible factors that could predict outcome of the treatment.Methods: Sixty-two patients with SCI (45 men and 17 women; mean age, 47.5 ± 15.5 [SD] years) from 5 specialized European SCI centers were offered treatment with transanal irrigation for a 10-week period. Bowel function was assessed at baseline and at termination using the Cleveland Clinic Constipation Scoring System (CCCSS; 0–30, 30 = severe symptoms), St. Mark's Fecal Incontinence Grading System (FIGS; 0-24, 24 = severe symptoms), and the Neurogenic Bowel Dysfunction score (NBD; 0–47, 47 severe symptoms). Factors predicting improvement in bowel function scores were identified using a general linear model.Results: Severity of symptoms at termination was significantly reduced compared with baseline values (CCCSS: −3.4; 95% confidence interval [CI], −4.6 to −2.2; FIGS: −4.1; 95% Cl, −5.2 to −2.9; NBD: −4.5; 95% Cl, −6.6 to −2.4; all P < 0.0001). Although several factors were associated with positive outcome, no consistent and readily explainable pattern could be identified. Surprisingly, hand function, level of dependency, predominant symptom, and colonic transit time were not associated with outcome.Conclusions: Transanal irrigation in patients with SCI reduces constipation, improves anal continence, and improves symptom-related quality of life. No readily obtainable factors could predict outcome, which might be because of the relatively low number of patients. This supports the use of trial and error as a strategy in deciding on a bowel management method for neurogenic bowel dysfunction.
