International Multicenter Prospective Transtar Registry

International Transtar Registry - Stapled Transanal Rectal Resection Performed With Contour Transtar Stapler in the Treatment of Obstructed Defecation Syndrome (ODS)

Obstructed Defecation Syndrome (ODS) describes a condition which is characterized by chronic constipation. The symptoms of ODS include abdominal pain or cramping, irregular bowel frequency and the feeling of not having emptied the rectum. ODS is usually associated with internal rectal prolapse and/or rectocele. For surgical treatment of ODS, a plethora of surgical techniques have been described with no one method having been assessed as a gold standard.

A new surgical procedure - Transtar - has been introduced in Europe recently. The goal of this registry is to assess safety, effectiveness and patient quality of life, associated with Transtar for chronic constipation due to morphological changes, such as internal rectal prolapse and rectocele.

Inclusion Criteria:

• Patients with obstructed defecation, fragmented defecation or incomplete evacuation as a presenting symptom documented by a standardized symptom score
• confirmed internal rectal prolapse or rectocele on dynamic defecography
• adequate external sphincter on rectal digital examination.

Exclusion Criteria:

• Subjects with any other surgical procedure than STARR for ODS
• Subjects in whom STARR is not performed with the Contour Transtar stapler
• Subjects with a physical or psychological condition which would impair participation in the registry.
