The Contour® Transtar™ operation represents a further methodological development of conventional transanal stapled rectal resection (STARR) for the treatment of obstructed defecation syndrome (ODS) and/or full thickness rectal prolapse. In contrast to the conventional STARR technique a specially designed single curved stapler is used with which the rectal wall is incised in a circular fashion and anastomosed. This results in a monoblock resection with almost unlimited extent of resection. In multicenter studies the procedure has generally been shown to be effective for treatment of ODS with intussusception and rectocele. In comparison to conventional STARR the resected tissue samples are larger and the functional effectiveness is comparable. Furthermore, data from prospective randomized trials revealed higher effectiveness in long-term follow-up. With reference to full thickness rectal prolapse, feasibility studies have been performed which showed low morbidity but long-term follow-up studies suggest a high recurrence rate of >40 %.
