Description

We neurophysiologically studied 5 patients-3 boys and 2 girls aged 10-15 years (mean: 13.0 years)-with ulcerative colitis and familial adenomatous polyposis by measureing pudendal motor nerve terminal la-tency and compared results with those for 16 healthy controls-10 boys and 6 girls aged 12-18 years (mean: 15.4 years). One year after closure of the diverting ileostomy, 4patients (80.0%) experiemced a small amount of soiling and had significantly longer pudendal motor nerve terminal latency than 2 years after closure and healthy subjects (p<0.01). Results suggest that soiling in 1 year postoperativelly is due to injury to the puden-dal nerve caused during surgery. Such damage improved 2 years after closure of the diverting ileostomy.
