Abstract:Objective：To evaluate the effect of pull-through and double stapling technique for sphincter preservation operation in super-low rectal carcinoma. Methods：The resection through pull-through and double stapling technique for sphincter preservation approach was performed on 46 patients with super-low rectal carcinoma from December 1997 to December 2005. The distance between the anal verge and the lower margin of the tumor was 4～ 7 cm（averaged 5.5 cm），including 26 patients in Dukes A stage，16 Dukes B and 4 Dukes C.Results：Fecal continences were preserved successfully in all patients．Only one got anastomosis leak（2.2％）after operation，and 4 cases had anastomotic narrowing（8.7％）within 1 year.At a median follow-up of 54 months，two patients had local recurrences（4.3％）. The 5 year survival rate was 81.3％. There was no urinary dysfunction in this series.The successful rates of sexual function after surgery were respectively as follows:man 82.4% and woman 83.3%. Conclusions：Pull-through and double stapling technique for sphinceter preservation operation was feasible and safe ，provide a original operative style for super-low rectal carcinoma.
