STARR with Contour^® Transtar^™: prospective multicentre European study

<jats:title>Abstract</jats:title><jats:p><jats:bold>Objective </jats:bold> The stapled transanal rectal resection (STARR) in patients with defecation disorders is limited by the shape and capacity of the circular stapler. A new device has been recently developed, the Contour<jats:sup>®</jats:sup> Transtar<jats:sup>™</jats:sup> stapler, in order to improve the safety and effectiveness of the STARR technique. The study has been designed to confirm this declaration.</jats:p><jats:p><jats:bold>Method </jats:bold> From January to June 2007 a prospective European multicentre study of consecutive patients with defecation disorder caused by internal rectal prolapse underwent the new STARR technique. The assessment of perioperative morbidity and functional outcome after 6 weeks, 3 and 12 months was documented by different scores.</jats:p><jats:p><jats:bold>Results </jats:bold> In all 75 patients, median age 64, the Transtar procedure was performed with 9% intraoperative difficulties, 7% postoperative complications and no mortality. The mean reduction of the ODS score was −15.6 (95%−CI: −17.3 to −13.8, <jats:italic>P</jats:italic> < 0.0001), mean reduction of SSS was −12.6 (95%−CI: −14.2 to −11.2; <jats:italic>P</jats:italic> < 0.0001). 41% stated improvement of their continence status by CCF score, only 4 patients (5%) had deterioration.</jats:p><jats:p><jats:bold>Conclusion </jats:bold> The Transtar procedure is technically demanding, with good functional results similar to the conventional STARR.</jats:p>
