Encopresis: a study of treatment alternatives and historical and behavioral characteristics.

The historical, demographic and pre/post treatment behavioral profiles of a Health Maintenance Organization's (HMO) encopresis patients were studied. The efficacy of two maintenance treatments were also compared. Management included an initial bowel evacuation, high fiber diet, behavior modification program, and random assignment to maintenance on oral laxatives or conditional rectal cathartics. Of the 136 patients evaluated, 61 completed treatment (oral 24; rectal 37). Significant behavioral problems were identified. However, the majority (65%) of patients were managed without psychosocial intervention and successful completion of treatment significantly improved most behaviors. There were no significant differences in efficacy between the oral laxative or conditional rectal cathartic maintenance groups completing treatment. In 87% success continued 6 to 12 months post-treatment.
