Aim Secondary sphincter repair has been the conventional management of anal incontinence ( AI ) when a structural defect in the sphincter is recognized. However, disappointing long‐term results have contributed to a tendency towards an increasing use of alternative treatment methods. This study aimed to assess the long‐term functional outcomes following a secondary sphincter repair in women with AI after obstetric sphincter injury. Method This is a questionnaire study of women who underwent a secondary sphincter repair in Denmark between January 1990 and December 2005. Patients were identified through the Danish National Patient Registry. Functional outcomes were assessed by a self‐administered questionnaire in 2010 and 2018. Primary outcomes were Wexner and St. Mark's scores. Impact on quality of life was assessed using the Fecal Incontinence Quality of Life Scale. Results Functional outcome was assessed in 370 women in 2010 and 255 women in 2018. At 18.3 [interquartile range ( IQR 15.0–22.0)] years of follow‐up, the mean ± SD Wexner score was 8.8 ± 4.8 and the mean St. Mark's score was 11.7 ± 5.0. Flatus incontinence was the most frequent symptom, reported by 97%. Incontinence for liquid and solid stools was reported by 75% and 54%, respectively. There were no significant changes in incontinence frequencies over time. Women with a Wexner score of ≥ 9 had a significantly lower quality of life score in all domains than did women with a Wexner score of < 9 ( P < 0.001). Conclusion At long‐term follow‐up, few patients are fully continent following a secondary sphincter repair. However, it appears that the functional results remain stable at very long‐term follow‐up.
