title: [Application of single stapler combined with prolapsing technique in anterior resection of ultra-low rectal cancer].
abstract: OBJECTIVE
  Evaluation of single stapler combined with prolapsing technique for anus-preserving of ultra-low rectal cancer and its indication as well as surgical procedure.
  
  
  METHODS
  Forty-three patients with ultra-low low rectal cancer suitable for anterior resection were divided into two groups, single stapler combined with prolapsing technique was applied for experiment group, conventional double stapler technique was applied for control group. To compare the distal margin, local recurrence rate, complications, anal continence function and expenses.
  
  
  RESULTS
  The distal margin of experimental group is significantly longer than that of control group (2.2 cm +/- 0.2 cm VS 1.9 cm +/- 0.4 cm, P = 0.006). The distance between dentate line and distal incision line of control group is much longer than experimental group (1.9 cm +/- 0.5 cm VS 1.3 cm +/- 0.3 cm, P < 0.001). There is no recurrence in experimental group but 3 cases recurrence within 1 year in control group. The anastomose fistula rate, instrument expenses of experimental group are less than those of control group. There is no distinct in anal continence between two groups. Occasional minor soiling is present in 1 case of experimental group.
  
  
  CONCLUSIONS
  Single stapler combined with prolapsing technique is superior to double stapler technique for anus-preserving of ultra-low rectal cancer.
