Study summary

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)

Inclusion criteria

  • Females aged 18 to 40 years.
  • Gestational age >37 weeks at the time of delivery.
  • Parity \<5.
  • History of one or more previous cesarean sections.
  • Intraoperative evidence of a thinned-out lower uterine segment scar during repeat cesarean section.

Exclusion criteria

Exclusion Criteria:

  • Preeclampsia (blood pressure ≥140/90 mmHg with proteinuria >+1 on dipstick).
  • Gestational diabetes mellitus.
  • Placental abnormalities, including placenta previa, placenta accreta spectrum (accreta/increta), or placental abruption.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

INR, PT and aPTT (clotting tests)

Blood tests of how long blood takes to clot. The INR is the prothrombin time (PT) put on a common scale; about 1 is usual for someone not taking a blood thinner.

Criteria often make an exception for people on a blood thinner such as warfarin, whose INR is raised on purpose.

What researchers measure

Primary outcomes

  1. Time to Achieve Hemostasis

    Time (in minutes) required to achieve complete hemostasis of the thinned-out lower uterine segment following application of the assigned suturing technique during repeat cesarean section.

    Time frame: During the surgical procedure (intraoperative)

  2. Time to Achieve Hemostasis

    Time (in minutes) required to achieve complete hemostasis of the thinned-out lower uterine segment following application of the assigned suturing technique during repeat cesarean section.

    Time frame: Intraoperative (during cesarean section)

Secondary outcomes

  1. Number of Sutures Required to Achieve Hemostasis

    Number of hemostatic sutures required to achieve complete hemostasis of the thinned-out lower uterine segment during repeat cesarean section.

    Time frame: Intraoperative (during cesarean section)

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Aug 2026 (actual). Primary completion is estimated for Dec 2026, 3 months after the start.

Of 173 non-industry interventional studies with no phase under Cicatrix, half reached primary completion within 20 months of starting (the median), counting those still running; a quarter within 9 and three quarters within 36. This study's planned 3 months is below that.

Counting every sponsor, half of 206 studies reached it within 18 months; a quarter within 8 and three quarters within 36.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 11, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
