Objective To assess the validity of transanal local excision for stage Ⅰ low rectal carcinoma.Methods The clinical data of 93 patients with stage Ⅰ low rectal carcinoma who underwent transanal excision (group A,n=45)or radical resection(group B,n=48)were retrospectively analyzed.Twenty-four T1 patients and 21 T2 patients in group A received postoperative adjuvant radiation therapy and adjuvant chemoradiotherapy,respectively.All patients in group B received radical surgery only.The 5-year survival rates,recurrence rates,and postoperative complications between the 2 groups were compared.Results The 5-year survival rates were 100%(24/24)for T1 patients,86%(18/21)for T2 patients in group A,and 100%(18/18)for T1 patients,93%(28/30)for T2 patients in group B,with no significantly statistical difference between the 2 groups(P>0.05).The recurrence rates were 4%(1/24)for T1 patients,19%(4/21)for T2 patients in group A,and 0(0/18)for T1 patients,7%(2/30)for T2 patients in group B,with no significance between the 2 groups(P>0.05).The incidence of postoperative complications in group A was 2%(1/45),which was significantly lower than that of 15%(7/48))in group B(P<0.05).Conclusions Transanal local excision of early low rectal carcinoma,combined with postoperative chemotherapy for T1 patients or chemoradiotherapy for T2 patients, results in a low complication rate and good sphincter function,and provides satisfactory local control and 5-year survival rates.
