Intensity of pain evaluated by VAS and duration of pain expressed in minutes after defecation

	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)
7th defecation	2.2 (0.7)	10.4 (5.1)
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 standard deviation. Student’s t test with Welch correction was used to compare the difference between each point. Significance. 1st defecation vs preoperative *p < 0.01
