Abstract
BACKGROUND A cesarean scar defect (CSD) is incomplete healing of the myometrium at the site of a prior cesarean section (CS), complicating more than half of all cesarean sections. While transvaginal ultrasound (TVU) is the most common modality for diagnosing this defect, hysteroscopy remains the gold standard. We aimed to develop an efficient diagnostic tool for CSD among women with abnormal uterine bleeding (AUB) by integrating TVU findings and participants' demographic features. METHODS A single-center cross-sectional study was conducted on 100 premenopausal and non-pregnant women with a history of CS complaining of AUB without a known systemic or structural etiology. Each participant underwent a hysteroscopy followed by a TVU the next day. The defect dimensions in TVU, patients' age, and the number of previous CSs were integrated into a binary logistic regression model to evaluate their predictive ability for a hysteroscopy-confirmed CSD. RESULTS Hysteroscopy identified 74 (74%) participants with CSD. The variables age, the number of CSs, defect length, and defect width significantly contributed to the logistic regression model to diagnose CSD with odds ratios of 9.7, 0.7, 2.6, and 1.7, respectively. The developed model exhibited accuracy, sensitivity, and specificity of 88.00%, 91.89%, and 76.92%, respectively. The area under the receiver operating curve was 0.955 (P-value < 0.001). CONCLUSION Among non-pregnant women suspected of CSD due to AUB, looking at age, the number of previous CSs, and TVU-based defect width and length can efficiently rule CSD out.

Best Pract Res Clin Obstet Gynaecol 2023; 90:102390. [PMID: 37506497 DOI: 10.1016/j.bpobgyn.2023.102390] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2023] [Revised: 07/03/2023] [Accepted: 07/06/2023] [Indexed: 07/30/2023]
Abstract
Of all neonates, 21% are delivered by cesarean section (CS). A long-term maternal complication of an SC is a uterine niche. The aim of this review is to provide an overview of the current literature on imaging techniques and niche-related symptomatology. We performed systematic searches on imaging and niche symptoms. For both searches, 87 new studies were included. Niche evaluation by transvaginal sonography (TVS) or contrast sonohysterography (SHG) proved superior over hysteroscopy or magnetic resonance imaging. Studies that used SHG in a random population identified a niche prevalence of 42%-84%. Niche prevalence differed based on niche definition, symptomatology, and imaging technique. Most studies reported an association with gynecological symptoms, poor reproductive outcomes, obstetrical complications, and reduced quality of life. In conclusion, non-invasive TVS and SHG are the superior imaging modalities to diagnose a niche. Niches are prevalent and strongly associated with gynecological symptoms and poor reproductive outcomes.

Abstract
BACKGROUND: Long-term sequelae of cesarean section (CS) is formation of niche in CS surgical scar. Blood glucose involved in wound healing process after CS.
AIM: This study was to find correlation of blood glucose level with niche in CS patients.
METHODS: This research was an observational and analytic study with case series design conducted at Department of Obstetrics and Gynecology, Universitas Sumatera Utara, RSUP H Adam Malik Medan, and Sundari Hospital Medan Starting from July to August 2022. To assess correlation between variables, eta test was used to assess the correlation of blood glucose with incidence of niche. The analysis results were said to be significant if p < 0.05, with 95% CI.
RESULTS: Mean of patients were in 21–29 years (70%), multiparity with 12 patients (40%), aterm gestational age with 30 patients (100%), 16 patients (53.3%) with anteflexion uterus, previous CS 2 times were the majority with 9 patients (30%), and 17 patients (56.7%) were elective CS. Incidence of niche was 63.3%. Triangular were the most found niche with 11 patients (36.7%). Mean of total myometrial thickness, depth of niche, and residual myometrial thickness were 5.23 ± 11.2 mm, 2.44 ± 2.75 mm, and 5.23 ± 11.22 mm, respectively. Mean blood sugar level was 103.3 ± 17.4 mg/dl. From eta analysis, there was no correlation between blood glucose levels post-CS patients using eta test with p = 0.872.
CONCLUSION: There was no significant correlation between blood glucose levels on niche incidence in post-CS patients.

Prediction of Scar Myometrium Thickness and Previous Cesarean Scar Defect Using the Three-Dimensional Vaginal Ultrasound. CONTRAST MEDIA & MOLECULAR IMAGING 2022; 2022:3584572. [PMID: 36262982 PMCID: PMC9556220 DOI: 10.1155/2022/3584572] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/30/2022] [Revised: 07/06/2022] [Accepted: 07/20/2022] [Indexed: 01/26/2023]
Abstract
This research aimed to explore the related factors of scar myometrial thickness and scar diverticulum formation and then predict the occurrence of uterine diverticula. 140 patients with cesarean section were selected as the research objects. According to the three-dimensional (3D) vaginal ultrasound echo and the diagnostic criteria of uterine diverticulum, the research objects were divided into a diverticulum group and a control group, with 70 cases in each group. Data such as age, number of cesarean sections, endometrial thickness, uterine position, and diverticulum size was collected, and their relationship with uterine diverticulum was compared and analyzed. The results showed that there were significant differences in menstrual days, cesarean section times, and uterine position between the two groups (P < 0.05). The height (9.02 ± 2.97), width (14.02 ± 3.08), and depth (5.14 ± 1.23) of the posterior uterine diverticula in the scar diverticulum group were all greater than the anterior uterine height (6.69 ± 1.36), the width (10.69 ± 2.15), and the depth (3.86 ± 0.69), respectively. The residual myometrium thickness in posterior position of the uterus (2.98 ± 0.75) was < anterior position of uterus (3.43 ± 0.47), and the difference was statistically significant (P < 0.05). Multivariate analysis showed that the frequency of cesarean section (1 time, 2 times), uterine position, and abnormal menstruation were independent risk factors in the scar diverticulum group (P < 0.05). In conclusion, menstrual abnormalities, the number of cesarean sections (1 time or twice), and the position of the uterus are independent risk factors for the formation of uterine scar diverticula. The deeper the diverticula, the more likely to have menstrual abnormalities, the more prone to diverticulum in patients with posterior uterus, and the deeper the diverticula in patients with 2 dissections.

Abstract
The definition of a cesarean scar pregnancy (CSP) is the localization of the gestational sac (GS) in the cicatrix tissue, which is created in the front wall of the uterus after a previous cesarean section (CS). The worldwide prevalence of CSP has been growing rapidly. However, there are no general recommendations regarding prophylaxis and treatment of the abnormalities of the anterior wall of the uterus discovered in a non-pregnant myometrium, or how to deal with existing cases of CSP. We present the latest knowledge, a holistic approach to the biology, histology, imaging, and management concerning post-CS scars based on our cases, which were treated in the Department of Pregnancy and Pathology of Pregnancy in the Medical University of Lublin, Poland. In our study, we present images of tissue samples of areas with a cicatrix in the uterus, and ultrasound and MRI images of CSP. We discuss the advances in the biology of the post-CS scar tissue, the prevention techniques used to repair the scar defect (niche) before the pregnancy, and the treatment of different complications of CSP, such as the rupture of the gravid uterus or the dehiscence of the myometrium.

Abstract
OBJECTIVES To review the definitions, diagnostic methods, risk factors, symptoms, and treatments for caesarean scar niche. METHODS Review of the literature, critical reflection, and pragmatic advice. RESULTS There is no consensus on the definition of caesarean scar niche. Some suggest an indentation≥2mm of the myometrium of the caesarean scar, but this is present in more than half of women with caesarean history and takes no account of woman's symptoms. The most popular diagnostic method is ultrasound±hysterosonography. Risks factors for niche are multiple Caesareans, Cesarean during labor with too low incision, and retroverted uterus. Symptoms include abnormal gynaecologic bleeding and pelvic pain, and their presence establish the "Caesarean scar syndrome". The risks of pregnancy with niche is poorly studied, but pregnancy is not contraindicated, even if the niche is untreated. The treatment of caesarean scar niche is mainly surgery and conservative. The former should be reserved for symptomatic patients, and those with secondary infertility and fertility treatment failure. Patients with residual myometrium thickness≥2.5mm may benefit from first-line hysteroscopic treatment, whereas a laparoscopic or vaginal approach could be offered in other cases. CONCLUSIONS A pragmatic definition of caesarean scar niche as a disease including symptoms is the necessary prerequisite for the management of women. The treatment is mainly surgical, or conservative depending on the desire for subsequent pregnancy.

Abstract
PURPOSE This work investigates ICSI outcome between LASER Artificial Shrinkage (LAS) and Micro-Needle Artificial Shrinkage (MNAS) before vitrification. PATIENTS AND METHODS Four hundred and nine women were included in the study; which were randomly divided into two groups according to the technique used for artificial shrinkage step of the blastocyst before vitrification: in the first group, Laser beam was used while in the second group the micro-needle was used. Ovarian stimulation was done before the ICSI procedure either by long, short or antagonist protocol. RESULTS The statistical analysis of our study revealed that there was no statistically significant difference between the two groups regarding age, number of cases, AMH, Basal FSH, BMI, male factor, usage ovarian stimulation protocol, high quality blastocysts, the mean number of transferred embryos. While, there was a statistically significant difference between two groups after thawing with p-value < .001 in favor of the LAS method regarding the morphology of originally high quality blastocysts, blastocysts healthiness (not degenerated), pregnancy rate, the implantation rates. CONCLUSION LASER artificial shrinkage of human blastocysts is a promising technology that could be implemented on a wider basis to improve ART practice, as our study revealed that the usage of LASER pulse for artificial shrinkage of blastocysts before vitrification has better implantation rate as well as better chemical and clinical pregnancy rate in comparison to the usage of micro-needle artificial shrinkage of blastocysts before vitrification. There is a statistically significant difference regarding live birth rate being more in the LASER group as compared to needle group, also the number of twins ether identical or non-identical are larger in laser group than in needle group but with no statistically significant difference.
