Detailed Description

Recently, The percentage of Cesarean section (CS) deliveries has dramatically increased in most countries. The presence of a niche at the site of a CS scar has been observed. A niche is mainly a sonographic finding defined as a triangular anechoic area at site of incision. ( Mascarello et al, 2017) Alternative terms for a niche are Cesarean scar defect (Wang et al, 2009), deficient Cesarean scar (Ofili-Yebovi et al, 2008), diverticulum (Surapaneni et al, 2008), pouch (Fabres el al, 2003) and isthmocele. (bogres el al, 2010) As not all women with previous CS develop a niche, it is a matter of interest to identify the risk factors that may predict their development. (Sholapurkar , 2018) Possible causes of this condition may be surgery or patient related. Surgery related factors as low cervical incision, incomplete closure of the uterus (decidual sparing) and inadequate hemostasis. Patient related factors may be attributed to infection. ( Vervoort et al, 2015) Cesarean scar niche may be asymptomatic or may cause a number of obstetrical and gynecological problems (cesarean scar syndrome) . ( Vervoort et al,2015b) Obstetrical complications of the niche are cesarean scar ectopic pregnancy, placenta previa and morbidly adherent placenta, cesarean scar dehiscence following incomplete abortion secondary to uterotonic drugs, Scar dehiscence and tender scar even scar rupture (Tanimura el al, 2015) Gynecological symptoms of the niche are postmenstrual spotting, Intermenstrual bleeding, Dysmenorrheal, Dysparunia and secondary infertility. (Tanimura el al, 2015) Various methods to detect and measure a niche have been described. The majority of papers have evaluated the niche with the use of transvaginal sonography (TVS) (Vaate et al, 2011), and contrast-enhanced sonohysterography (SHG) (Bij de Vaate et al, 2011), but a minority have used hysteroscopy (El-Mazny et al, 2011) or hysterosalpingography. (Surapaneni and Silberzweig, 2008 ) At present there is no consensus regarding the gold standard for the detection and measurement of a niche. (Vaate et al, 2014) Symptomatic cesarean scar niche (cesarean scar syndrome) can be managed conservatively using combined oral contraceptive pills especially in women not seeking fertility, or it can be treated using minimal invasive surgery as hysteroscopic resection (vervoot et al,2017) , laparoscopic repair (ma et al,2017) or vaginal repair (Yao, 2014) In this study we will evaluate laparoscopic management of cesarean scar niche

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.
  • Phase 2
  • Phase 3

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.

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
post-menstrual spotting
Time Frame: 6 month after intervention
number of days of post-menstrual spotting "spotting or bleeding after 8 days of menstruation whatever the amount
6 month after intervention

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.
Outcome Measure
Measure Description
Time Frame
menstrual related pain
Time Frame: 6 month after intervention
degree of menstrual related pain as descriped by the patient on Visual Analogue Scale of pain from 1 to 10
6 month after intervention
infertility
Time Frame: 6 month after intervention
