AIM OF THE STUDY: The aim of this study was to assess the oncology and functional outcome after preoperative radiotherapy and delayed coloanal @entity254 for @entity5 of the lower third of the rectum. @entity1 AND METHODS: From January 1988 to December 1997, 35 @entity1 received preoperative radiotherapy (45 Gy) followed by rectal resection through a combined abdominal and transanal approach. Thirty @entity1 had preoperative @entity5 staging with endorectal ultrasonography: uT1N0 = 2, uT2N0 = 6, uT2N+ = 2, uT3N0 = 6, and uT3N+ = 14. Colorectal resection was performed on average 32 days after the conclusion of radiotherapy, and the distal colon stump was pulled through the anal canal. On postoperative day 5, the colonic stump was resected and a direct coloanal @entity254 performed. RESULTS: Pathological examination of the specimens revealed @entity5 sterilization in two cases, pT1N0 = 3, pT2N0 = 14, pT2N+ = 1, pT3N0 = 6, and pT3N+ = 9. There was no postoperative mortality and there was no leakage. One @entity1 had a @entity530 , and another one had @entity39 which required re-operation. Median follow-up was 43 months (range 6-113). Two @entity1 had locoregional recurrence, seven had distant metastasis, and 3 had both. Actuarial survival rate at 1, 3 and 5 years was 97%, 86%, and 72% respectively. The rate of local control at 5 years was 78%. Functional results were evaluated by a new scoring system. Function was considered good in 59 and 70% at 1 and 2 years respectively. CONCLUSION: This new procedure is a safe and effective sphincter-preserving operation that avoids a diverting stoma. It is well adapted for @entity1 receiving preoperative radiotherapy, with low local morbidity and good functional results.
