Characteristics of anatomic remodeling of pelvic diaphragm hiatus in postpartum women with constipation detected dynamically by transperineal three-dimensional ultrasonography
Objective To have a dynamic observation about the morphological characteristics of pelvic diaphragm hiatus in postpartum women with constipation by transperineal three-dimensional ultrasonography. Methods From Jul.2014 to Jun. 2017, 110 postpartum women underwent transperineal 3-D ultrasound investigation at Department of Obstetrics and Gynecology，including 45 postpartum women with constipation and the other 65 postpartum women without constipation．In the mean time，100 normal nulliparous healthy women without constipation were chosen as control group．The morphological characteristics of pelvic diaphragm hiatus，the perimeter and area of pelvic diaphragm hiatus，levatorani thickness were measured at rest, on maximum pelvic floor contraction and maximum Valsalva by 3-D ultrasound, respectively. Results Loose connective tissue was observed in postpartum women．The perimeter and area of pelvic diaphragm hiatus and levatorani thickness were significantly increased than those in control group, at rest, on maximum pelvic floor contraction and maximum Valsalva respectively (P＜0.05).And the perimeter and area of pelvic diaphragm hiatus in postpartum women with constipation were increased than those without constipation at three maneuvers，respectively (P＜0.05)．Levatorani thickness in postpartum women with constipation was significantly thinner than those without constipation at maximum pelvic floor contraction (P＜0.05), but there was no significant difference between postpartum women with constipation and without constipation at rest and on maximum Valsalva in pubovisceral muscle thickness (P＞0.05)．Conclusions Pelvic diaphragm hiatus anatomic remodeling is identified in postpartum women. Transperineal three-dimensional ultrasonography is of great value for pelvic diaphragm hiatus change in postpartum women ,especially those with constipation．
