Impact of purse-string uterine suture on scar healing after a cesarean delivery: a randomized controlled trial.

Background: Uterine closure technique can affect scar healing, potentially resulting in unfavorable gynecologic and life-threatening obstetrical outcomes. Double-layer continuous unlocked suture has been demonstrated to promote optimal residual myometrial thickness. Recently, the purse-string uterine suture technique has emerged as a viable method to enhance the healing of scars.
