Uterine caesarean closure techniques affect ultrasound findings and maternal outcomes: a systematic review and meta-analysis.
Impact of adding a second layer to a single unlocked closure of a Cesarean uterine incision: randomized controlled trial
This study by the Coronis Collaborative Group (Lancet, 2016) aimed to determine if there were differences in maternal morbidity depending on which of five surgical techniques for caesarean section a woman received.
Randomized Control Trial
13,153 women were followed up with for a mean duration of 3.8 years after receiving a C-section through one of five surgical techniques. The five pairs of alternative surgical techniques surveyed were blunt vs. sharp abdominal entry; exteriorization of the uterus vs. intra-abdominal repair; single vs. double layer closure of the uterus; closure vs. non-closure of the peritoneum; and chromic catgut vs. polyglactin-910 sutures.
The study found no evidence to prefer one surgical technique over another based on the following outcomes
