Anatomic sphincteroplasty with combined reconstruction of internal and external anal muscles in the anal incontinence surgical treatment.

Several groups studying the results of the classic sphincteroplasty show improvement of 75% of patients treated in a short-term follow-up, with a worsening of this data in the long-term follow-up down to an improvement of 50% of the patients. Some other groups published more optimistic results, showing an 80% success rate without any deterioration of the technique over time after introducing a separate repair of the internal and external muscles. We think that the introduction of some modifications in the classic technique, named "Anatomic sphincteroplasty with combined reconstruction of external and internal anal sphincter muscles" may obtain very good clinical and anorectal manometric results both in a short and mid-term follow-up. In addition, increasing the pressive length in the anal canal may contribute to maintain more stable results over time.
