Objective  To study the value of transanal pull-through combined with single stapling technique for anus conservation in surgical resection of low rectal carcinoma.    Methods  A total of 112 patients with low rectal carcinoma admitted to our hospital in January 2004-February 2009. Double stapling technique（DST）and transanal pull-through combined with single stapling technique (SST) were performed in 75 and 37 patients

respectively

to conserve anus during surgical resection of their rectal carcinomas.    Results  The anus of all patients was conserved with no death occurred during operation. No infiltration of cancer cells was observed at the incision margin after operation. No difference was found in operation time

blood loss and mean hospital stay time between the two groups. Anastomotic leakage occurred in 3 patients of DST group but not in any patients of SST group. The patients were followed up for 4-65 months (mean 15 months)

during which recurrence of cancer in pelvic cavity and anastomosis stoma and liver metastasis were found in 3

2 and 7 patients of the DST group respectively

while recurrence of cancer in pelvic cavity was found in 1 patient but not in anastomotic stoma in any patient

and liver metastasis was detected in 4 patients of the SST group.   Conclusion  Transanal pull-through combined with SST is a simple and safe procedure for effective anus conservation in surgical resection of low rectal carcinoma with a low recurrence rate.
