To find out whether a change in suturing technique might affect the healing of the uterine scar after caesarean section (CS).


In this randomised prospective study, 78 term pregnant patients delivered by CS were allocated to two different suturing techniques either including or excluding the endometrial layer. The integrity of the uterine incision was checked by ultrasound 40-42 days after the operation. Any deviation from the full thickness apposition of the anterior uterine wall (with the ratio: [anterior wall thickness/(anterior wall thickness+height of the wedge shaped defect)]<1) was considered to represent incomplete healing. Both groups were then compared in terms of the frequency of incomplete healing. Chi square and Student's t-test were used where appropriate. A logistic regression model was used to adjust for confounding factors.


The frequency of incomplete healing was significantly lower in the group treated by full thickness suturing (44.7% versus 68.8%); (OR: 2.718; CI: 1.016-7.268). Similarly the mean values for the incomplete healing ratio were 0.77+/-0.17 and 0.86+/-0.17 (p = 0.03) in split and full thickness groups, respectively. After adjusting for other confounding factors the suture technique still remained as a significant determinant of the incisional healing (p = 0.04).


By selecting full thickness suturing technique one may significantly lower the incidence of incomplete healing of the uterine incision after CS.
