	Intensity of pain	Duration of pain
Preoperative	8,5(1,3)	165(40,3)
1st defecation	4,2(1,5)*	100(35,1)*
3rd defecation	4,1(1,1)	60,5(20,8)
5th defecation	3,0(0,6)	30,2(12,3)

9th defecation	0,8(0,3)	5,1(2,8)
10th defecation	0,2(0,4)	2,8(0,7)

Values are expressed as mean and (SD). Student’s t test with Welch correction was used to compare the difference between each point.Significance. 1st defecation vs preoperative ^*P<0,01 ^*P<0,01
