BACKGROUND: Several new therapies, including advancement flaps and fibrin glue, have been proposed for fistula in ano, with conflicting results. Most colorectal surgeons continue to use classic methods, e.g. fistulotomy, fistulectomy, a combined method, loose or cutting seton, and rubber loop. The aim of the present study is to report the outcome of our patients, operated on by such methods.
METHODS: We retrospectively reviewed the clinical records of 844 patients treated for anal fistula over a 30-year period, and assessed fistula morphology, surgical procedure and healing period. For patients treated 2 or more years prior to this study, we evaluated rates of persistent fistula and relapse, as well as prevalence of incontinence and patient satisfaction.
RESULTS: The majority of patients had trans-sphincteric fistulae (58.3%). We observed 274 secondary extensions (32.5%); these were common in all fistula types except for intrasphincteric fistulae. Most patients were treated by fistulotomy alone (594 patients, 70.4%) or by the combined fistulectomy-fistulotomy method (237 patients, 28.1%), with or without loose seton. All patients with trans-, supra- and extrasphincteric fistulae were re-examined in the operations theatre. Follow-up data were available for 652 (87%) of 751 patients at least two years after surgery. The anal fistula persisted in 3.2% and recurred in 2.1% of cases. A second procedure lowered the initial rate of unsuccessful operations from 5.3% to 2.5%. Continence disorders were reported in 6.9% of patients: 4.0% complained of incontinence to gas, 2.6% to liquid and 0.3% to solid feces.
CONCLUSIONS: Fistulotomy and fistulectomy with loose seton supported by preoperative anal manometry and postoperative evaluation under anaesthesia are followed by good clinical and functional results.
