RESUMEN
<p><b>OBJECTIVE</b>To evaluate the efficacy of transsacral local wide resection for mid-lower rectal tumors.</p><p><b>METHODS</b>Clinical data of 133 patients undergone transsacral local wide resection for mid-lower rectal tumors between September 1994 and September 2005 were analyzed retrospectively.</p><p><b>RESULTS</b>No patient died during operation. Fecal fistula occurred in 6(4.5%) patients. Negative resection margin was proved histologically in all the patients. Postoperative diagnosis was adenoma in 28 patients, hyperplastic polyp in 3 patients, carcinoid in 8 patients, gastrointestinal stromal tumor in 1 patient,adenoma with intra-mucosal carcinogenesis in 29 patients and adenocarcinoma invading into submucosa in 64 patients. Median follow-up was 76 months in 64 patients with T(1) adenocarcinoma, whose 5-year cumulative local recurrence and overall survival were 2.0% and 100% respectively. No local recurrence was observed in other patients.</p><p><b>CONCLUSION</b>Transsacral local wide resection is simple and safe for mid-lower rectal tumors, which is an appropriate procedure for mid-lower rectal benign tumor and can serve as a sphincter-saving operation for selected T(1) lower rectal carcinoma.</p>
