BACKGROUND: To determine the long-term outcome of postanal repair, and to assess whether the preoperative and physiological tests had any bearing on this outcome. Review included an opportunity for assessment with anal manometry and anal ultrasound. METHOD: Review of all patients (n = 22) over a 10 year period from 1986 to 1996. Comparison was of pre-operative symptoms to symptoms at review. Correlation of outcome with pre-operative manometry and the results of manometry and ultrasound at review (n = 6) was determined. RESULTS: Assessment was possible in 19 of the 22 patients. Follow-up ranged from 2 to 10 years (median, 8 years). Two had stomas created at 6 and 9 months and are considered failures. Seven patients considered the operation a success, in four it improved their symptoms and in six it was considered a failure. Comparison of pre- and postoperative symptoms scores found a statistically significant improvement (P = 0.0093; two-tailed Wilcoxon signed rank sum test). The outcome was not influenced by the results of pre-operative anal manometry. Anal ultrasound found five sphincter defects in six patients. Such defects did not preclude improvement from postanal repair. CONCLUSIONS: Although the results showed improvement or success in only 11 (58%) of the patients this was felt to be important given that these patients may have few alternatives other than complicated procedures or a stoma. Postanal repair has a place in the management of faecal incontinence.
