    Abstract:
    PURPOSE: This study aims to introduce a new anastomotic technique-transanal pull-through combined with single stapling technique (PT-SST), and evaluate the value in the sphincter-preserving operation for lower rectal carcinoma. METHODS: Between January 2004 and September 2011, 131 consecutive patients had sphincter-preserving operations using PT-SST and double stapling technique (DST) for low colorectal anastomosis. The data was prospectively collected. RESULTS: There are 45 patients (male 26, median = 55 years) in PT-SST group and 86 (male 46, median = 55 years) in the DST group. Anastomotic leakage took place in three patients in DST group, while no anastomotic leakage happened in PT-SST group. There are recurrences in pelvic cavity for one patient (2.2 %), in anastomotic stoma for no patient, and hepatic metastasis for four patients (8.9 %) in PT-SST group; while there are recurrences in pelvic cavity for three patients (3.5 %), in anastomotic stoma for two patients (2.3 %), and hepatic metastasis for seven patients (8.1 %) in DST group. No significant difference was indicated in the terms of the recurrence and hepatic metastasis between the two groups. Patients were satisfied with functional results. CONCLUSIONS: This new technique can solve some technique problems of DST and has at least comparable outcomes compared with DST. It is a safe and feasible procedure for performing low anastomosis with high rate of sphincter preservation. It can be used especially for patients with small pelvis.
