    Abstract:
    PURPOSE: This study was designed to determine the anastomotic leak rate, local recurrence rate, and survival of patients undergoing anterior resection with the double-stapling technique for rectal cancer. METHODS: Between 1981 and 1992, 189 patients underwent a curative (166) or palliative (23) anterior resection using the double-stapling technique. A chart review was performed, and follow-up information was obtained from the patient or family physician. Follow-up was complete in 186 patients (98 percent). RESULTS: There were five (2.6 percent) stapler-related complications, of which two patients required a defunctioning colostomy. Postoperative mortality was 1.6 percent, and clinical leak rate was 7.3 percent. Clinical leak rate was significantly higher in patients with lesions in the lower third (20 percent) compared with those in the middle and upper thirds (9 and 1 percent, respectively; P < 0.05). After a mean follow-up of 32 +/- 29 months, local recurrence rate was 9.1 percent but was significantly higher in patients more than 65 years old (14 vs. 1 percent; P < 0.005) and in patients with resection margins less than 2.0 cm (17 vs. 5.5 percent; P < 0.05). Five-year survival was 78 percent. CONCLUSIONS: Anterior resection performed with the double-stapling technique has an acceptable clinical leak rate, local recurrence rate, and survival rate. However, the clinical leak rate appears to be increased in patients with low tumors and, therefore, a defunctioning colostomy should be considered. Resection margins of more than 2 cm are necessary.
