Abstract
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.
