    Abstract
  •   Objective  The ultrasonic characteristics of the rectus abdominis in women with different delivery methods may be different, however, the clinical experience is not rich. Therefore, this study aims to observe the influence of delivery methods on the ultrasonic characteristics of the rectus abdominis in women in the early postpartum period.  Methods  A total of 200 women who underwent postpartum examinations at Zhuji Maternal and Child Health Hospital from August 2020 to October 2022 were taken as the study subjects. All of them underwent high-frequency ultrasound examination of the rectus abdominis. The incidence of diastasis recti abdominis (DRA) in the study subjects was statistically analyzed. The incidence of DRA, the thickness of the rectus abdominis and the difference of inter-recti distance (IRD) values in different delivery modes, different locations and different conditions were compared. The ultrasound characteristics of the midline abdominis and the echo characteristics of the rectus abdominis in DRA women and non-DRA women were observed.  Results  Between 6 and 8 weeks postpartum, the overall incidence of DRA in the vaginal delivery group (62.12%, 82/132) was significantly lower than that in the cesarean delivery group (82.35%, 56/68), P < 0.05, and the incidence of DRA in the upper, lower and 3 cm above umbilicus was significantly lower than that in the cesarean group (all P < 0.05). The thickness of rectus abdominis muscle [(0.79±0.11) cm, (1.13±0.18) cm, (0.71±0.09) cm] in the supine, flexed and upright positions of women in the vaginal delivery group were significantly higher than in the cesarean delivery group [(0.68±0.10) cm, (0.98±0.16) cm, (0.64±0.08) cm], all P < 0.05, and the IRD values at different positions in the supine, flexed and upright positions were significantly lower than those in the cesarean delivery group (all P < 0.05). There were statistically significant differences between DRA and non-DRA women in mid-abdominal ultrasound characteristics and rectus abdominis echo characteristics (all P < 0.05).  Conclusion  The incidence of DRA in the early postpartum period is higher in women who have had a cesarean section than in women who have had a vaginal delivery. The rectus abdominis is thinner, and the IRD is larger. In women with DRA, the midline of the abdomen is wider, and the echo of the rectus abdominis is more enhanced.
