Cesarean section uterine incisions can be closed either with a single layer or a double layer of sutures. In the 1990’s, the single-layer technique was touted as having fewer complications and became pretty widely accepted in the medical community, because short term, it seemed like the single layer technique was better. There have been questions raised about whether a single layer closure is linked to complications in the long term, specifically with a subsequent pregnancy. This episode answers the question as to whether a single or double layer suture is better in the short and long term and includes the available research on the two methods.
