PURPOSE: This study was designed to determine whether advancing age affects
the outcome of anal sphincter repair in patients with obstetric trauma and
fecal incontinence. METHODS: Anal sphincter repair was performed on 24 pat
ients younger than 40 (median age, 30) years and on 14 patients older than
40 (median age, 57) years. All patients had previous obstetric trauma. RESU
LTS: Twenty patients younger than 40 years (83 percent; 95 percent confiden
ce interval, 63-95 percent) became continent, or incontinent to flatus only
, after anal sphincter repair, whereas four patients had unchanged incontin
ence. Among patients order than 40 years, six patients (43 percent; 95 perc
ent confidence interval, 18-71 percent) became continent, whereas eight pat
ients remained incontinent (40 percent difference in functional outcome bet
ween younger and older patients; 95 percent confidence interval, 10-70 perc
ent). CONCLUSION: Older females have a poorer outcome of anal sphincter rep
air for obstetric trauma compared with younger females.
