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.
