Postanal repair: which patients derive most benefit?
Forty-two patients (37 women, 5 men; mean age 61 years) with varying degrees of anal sphincter dysfunction were treated by postanal repair. Results were analysed in relation to age, sex, presenting complaint and the results of preoperative anorectal physiological tests. Complete continence was restored in 13 (31%), while acceptable but slightly impaired control was achieved in a further 17 (40%). Twelve patients (29%) remained or became totally incontinent. The likelihood of a successful outcome was greater in those presenting with complete incontinence (77% improved) than in those retaining control of solid stool (29% improved, 29% unchanged, 43% worse). Age and sex had no effect on results but pudendal neuropathy, identified in 74% overall, slightly reduced the chance of success. In nine postoperative patients studied, neither the anorectal angle nor anal canal length bore any relation to the results of surgery.
