Abstract

OBJECTIVE
To understand the difference of defecation physiology between postpartum and postoperative women.
METHODS
Between July 1998 to April 1999, we performed defecogram and pudendal nerve motor latency to 31 women, who were 8 postoperative women, 9 post cesarean-section state women, and 14 normal vaginal delivery-state women.
RESULTS
According to the defecogram results, only squeezing angles of the anorectal angle were significantly increased(96.0 vs 72.3, 74.9 degree) in normal vaginal delivery-state women compared to post cesarean-section state and postoperative women, but rest and evacuation angles were not. And to pudendal nerve latency, there were no statistically significant difference.
CONCLUSION
We concluded that the pudendal plexus was damaged during labor, therefore its ability to control puborectalis muscle was damaged. So, the anorectal angles of squeezing of postpartum women were significantly increased, compared to those of post cesarean section women or postoperative women.
