Rectal static disorders, including the rectocele, represent a frequent functional pathology which affects the quality of life of affected patients. Among vaginal treatments, the STARR technique corresponds to rectal resection by transanal approach using a stapler. The American Gastroenterology Association (AGA) has concluded that service to patients is insufficient. The technical and functional results published are mostly short-term studies. The investigators seek to assess the technical and functional results of Operation STARR, based on a series of consecutive expert center cases, to confirm or refute the conclusions of the AGA recommendations.
