[Vital preoperative function diagnosis in deep anterior rectum resection].

Restoration of continuity after deep anterior resection may lead to major functional problems. Preoperative functional evaluation of the anal sphincter should help to select patients unsuitable for reconstruction and produce more objective data for evaluation of new technical procedures. In addition to a standardized history of continence and the clinical examination, anorectal manometry and endosonography of the sphincter are adequate methods.
