Objective To evaluate the effect of total mesorectal excision with single stapling technique for low positioned rectal cancer.Methods Based on total mesorectal excision,56 cases of low positioned rectal cancer underwent anal preserving operation with single stapling technique and purse-string forceps.The 2 years follow-up result was retrospectively analyzed on radical resection effect,defecating function,complication rate and recurrent rate.Results All the resection margins were clear and had no intraoperative death,anastomotic leakage or occurrence of incontinence.Anastomotic stricture rate was 4%(2/56) and local recurrent rate was 5%(3/56).The patients were satisfied with anal function.Conclusion Based on total mesorectal excision,anal preserving operation for low positioned rectal cancers using single stapling technique and purse-string forceps can improve the postoperative quality of life,that is safe,feasible,practical and economical.
