Single-versus double-layer closure of the hysterotomy incision during cesarean delivery and risk of uterine rupture

摘要

Techniques used for closure of the hysterotomy site following cesarean delivery include the use of interrupted, locked, and unlocked continuous sutures with single- or double-layer closure. The specific technique used may be associated with risk of uterine rupture during a trial of labor (TOL) in future pregnancies. In a recent systematic review, single-layer closure but not double-layer closure was shown to reduce operating time and blood loss. However, a large randomized controlled trial published in 2010 found no such benefit for single-layer closure.
