title: [Application of sigmoid coloplasty in super-lower anastomosis].
abstract: OBJECTIVE
  To assess the clinical value of sigmoid coloplasty of super-lower anastomosis.
  
  
  METHODS
  Thirty-five patients underwent sigmoid coloplasty (treatment group), while 33 patients received straight sigmoidorectostomy (control group). Complication rate and anal function were observed and compared between the two groups.
  
  
  RESULTS
  The complication rate was 17.1% and 21.2% in the study group and control group respectively (P> 0.05). Average stool frequency were 2 times (1-5.5 times) a day in the study group and 3.5 times (1-9 times) a day in the control group 12 months after operation (P< 0.01). The fecal continence and self-satisfaction were improved significantly in the study group than that of the control group(P< 0.01, respectively). The postoperative anal function score was 2.57 in the study group and 7.21 in the control group, there was significant difference between the two groups (P< 0.01).
  
  
  CONCLUSIONS
  Compared with straight sigmoidorectostomy, sigmoid coloplasty applied in super-lower anastomosis can significantly improve the recovery of anal function without increasing complication rates.
