Objective:
To compare the quality of the uterine scar with one or two layer closure after caesarean section by studying biomechanical and pathological properties of the scar.
Methods:
A randomized controlled trial performed on eight term pregnant ewes assigned into two groups during caesarean according to type of uterine closure: single-layer or double-layer. Hysterectomy was performed 8 months after caesarean delivery. Tensile strength of all scars and of unscarred myometrium was measured. Pathological properties of the scars were analyzed histologically.
Results:
The force required to reach the yield point was similar between scarred and unscarred myometrium (p=0.96), and between the scars in single-layer and double-layer closure groups (p=0.65). There was a significant increase in fibrosis width on the superficial part of the uterus in the double-layer closure group compared to the single-layer group (p=0.02).
Conclusions:
Double-layer uterine closure modified wound healing without significant change in biomechanical properties.
