Comparison of Purse String Suture vs Transverse Mattress Suture to Maintain Hemostasis in Thinned-out Caesarean Sections Scars

August 10, 2026 updated by: Natasha Bushra

Brief Summary The goal of this clinical trial is to compare the effectiveness of purse-string suture versus transverse mattress suture for achieving hemostasis in women with thinned-out lower uterine segment scars undergoing repeat cesarean section. The study aims to determine whether the purse-string suture technique provides faster and more effective hemostasis than the transverse mattress suture technique.

The main questions it aims to answer are:

  • Does the purse-string suture reduce the time required to achieve hemostasis compared with the transverse mattress suture?
  • Does the purse-string suture reduce the number of additional sutures required to achieve adequate hemostasis? Researchers will compare purse-string suturing with transverse mattress suturing to determine which technique achieves hemostasis more efficiently in women with thinned-out cesarean section scars.

Participants will:

  • Undergo repeat cesarean section under standard surgical care.
  • Be randomly assigned to receive either purse-string suturing or transverse mattress suturing for repair of the thinned-out lower uterine segment after closure of the first uterine layer.
  • Have the time required to achieve hemostasis and the number of sutures required recorded intraoperatively.
  • Receive routine postoperative management according to institutional protocols. Suggested improvement

Although the thesis mentions only time to achieve hemostasis and number of sutures as outcomes, ClinicalTrials.gov prefers that the primary outcome be clearly identified. Since your sample size was calculated using time to achieve hemostasis, I recommend presenting it as:

  • Primary outcome: Time to achieve hemostasis (minutes)
  • Secondary outcomes: Number of sutures required for hemostasis; duration of cesarean section (minutes)
