Cesarean Scar Defects After Uterine Closure by Double-layer Barbed or Smooth Suture

December 27, 2022 updated by: Fabio Barra, Ospedale Policlinico San Martino

A Prospective Pilot Study Comparing Incidence and Characteristics of Cesarean Scar Defects After Uterine Closure by Double-layer Barbed or Smooth Suture

Late sequelae of a cesarean section related to a uterine scar defects include gynecological symptoms and obstetric complications. The aim of this study was to evaluate the incidence and characteristics of cesarean scar defects after uterine closure by double-layer barbed suture.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Sampling Method

Non-Probability Sample

Study Population

Patients who underwent elective cesarean section at ≥37 weeks of gestation

Description

Inclusion Criteria:

- Patients who underwent elective cesarean section at ≥ 37 weeks of gestation

Exclusion Criteria:

  • Patients who underwent concomitant surgical procedures during the cesarean section (i.e., tubal sterilization);
  • Patients who underwent a previous abdominal surgery (with exception of appendectomy) including a cesarean section or other laparotomic/laparoscopic uterine surgical procedure (i.e., myomectomy);
  • Patients who had a previous diagnosis of Mullerian uterine anomalies elective cesarean for the second time or after uterine surgery;
  • Patients who had evidence of PAS disorders or placenta previa.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of uterine scar defects
Time Frame: 6 months after the cesarean section
Number of simple and complex uterine scar defects is evaluated by transvaginal ultrasound

12 months after the cesarean section
Number of uterine scar defects
Time Frame: 24 months after the cesarean section

24 months after the cesarean section

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
