Results of external sphincter repair in Crohn's disease

Abstract
The results of anal sphincter repair in a group of six patients with anorectal Crohn's disease are reported. All patients had previously undergone anal surgery which was followed by faecal incontinence in five. The sixth patient became incontinent following obstetric injury. Of the six patients, five are completely continent and one has a permanent stoma (follow-up from 18 months to 16 years, mean 7·8 years). Anal sphincter repair in this highly selected group of patients with Crohn's disease has not been complicated by wound breakdown or fistula formation, and has given good results.
