STARR with Contour Transtar for Obstructed Defecation Syndrome: Long-Term Results.

Introduction: Obstructed defecation syndrome (ODS) is a widespread and disabling syndrome. With this study, we want to evaluate the long-term results of stapled transanal rectal resection (STARR) performed with Contour Transtar device in the treatment for ODS. A re-evaluation of 113 patients subjected to STARR from June 2007 to January 2010 was conducted. Methods: All the patients treated for symptomatic ODS with STARR with Contour Transtar were included in the study. We re-evaluate all patients treated in the study period with clinical examination and specific questionnaire to verify the stability of the functional results and the satisfaction at 5 years from surgery. Constipation was graded using the Agachan-Wexner constipation score; eventual use of aids to defecate and patient satisfaction were assessed preoperatively, 6 months and 5 years after surgery. Long-term complications were also investigated. Results: Constipation intensity decreased from the preoperative value of 15.8 (±4.9) to 5.2 (±3.9) ( p < 0.0001) at 6 months and remained stable after 5 years (7.4 ± 4.1; p < 0.01). Patients who use laxatives and enema decrease from 74 (77%) and 27 (28%) to only 16 (17%; p < 0.001) and 5 (5%; p < 0.001), respectively, at 5-year follow-up. None continue to help themselves with digitations after surgery. Also the satisfaction rate remained stable (3.64 vs 3.81) during the 5 years of the study. Conclusion: The long-term results have demonstrated the efficacy of the STARR with Contour Transtar in treating ODS and the stability over time of the defecatory improvements.
