Cesarean section uterine incisions can be closed either with a single layer or a double layer of sutures. In the 1990s, the single-layer technique was touted as having fewer complications. It became pretty widely accepted in the medical community because it seemed like the single-layer technique was better in the short term. Questions have been 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.
