Macrophage polarisation in caesarean scar diverticulum

AimsTo determine immunohistochemical features and correlations between M1/M2 polarisation status with disease severity of post-caesarean scar diverticulum (CSD).MethodsHistological and immunohistological stainings were performed and inflammatory (CD16, CD163 and tumour necrosis factor-α (TNF-α)), fibrosis (α-smooth muscle actin (α-SMA)) and angiogenic (CD31) markers were examined in uterine tissues collected from patients with uterine scar diverticula (CSD) (n=37) and caesarean section (CS) (n=3).ResultsCSD tissues have higher expression of α-SMA, TNF-α, CD16 and CD31 and lower expression of CD163 than CS tissue (p<0.05). Compared with adjacent tissues, thick-walled blood vessels, glands and fibrotic sites have higher expression of α-SMA, TNF-α and CD16. Statistical correlation was observed between the expression of CD16 and TNF-α (R=0.693, p<0.001), α-SMA (R=0.404, p<0.05) and CD31 (R=0.253, p<0.05) in CSD tissues, especially with the ratio of CD16/CD163 (R=0.590, p<0.01). A more significant difference was observed between the expression of CD16/CD163 and α-SMA (R=0.556, p<0.001), TNF-α (R=0.633, p<0.0001) and CD31 (R=0.336, p<0.05).ConclusionsIn this study, TNF-α, α-SMA, CD16 and CD31 proteins were overexpressed in all CSD cases, and CD16/CD163 was positively correlated with tissue inflammation, fibrosis and neovascularisation. Abnormal mononuclear macrophage infiltration may be involved in the origin and progression of CSD.

Evaluation of the necessity of laparoscopic repair of a uterine scar defect for cesarean scar pregnancy

Objective This study aimed to determine the risk factors associated with the necessity of laparoscopic scar defect repair for cesarean scar pregnancy (CSP). Methods We retrospectively analyzed 237 patients with CSP who were treated by ultrasound-guided suction curettage and/or laparoscopy in our hospital from April 2012 to November 2019. A total of 199 of these patients underwent ultrasound-guided suction curettage without uterine scar defect repair, while 38 of these patients underwent laparoscopic resection and uterine scar defect repair. We analyzed various clinical variables and compared the efficacy of treatment between the two groups. Results Gestational age, the maximum transverse diameter (MTD) of the gestational sac, myometrial thickness, the operation time, intraoperative blood loss, and the duration of the hospital stay were significantly different between the two groups. Gestational age, the MTD of the gestational sac, and myometrial thickness were independent risk factors for laparoscopic repair. Conclusions Gestational age, the MTD of the gestational sac, and myometrial thickness are important factors associated with the necessity for laparoscopic repair of a uterine scar defect.

Multigravid Women with Uterine Rupture: A Case Report

Introduction: Uterine rupture is the discontinuation of the uterine scar that creates connection between uterine and peritoneal cavity. The most common etiology for uterine rupture is dehiscence of uterine scar tissue from previous cesarean section. In patient with uterine rupture and fetal expulsion to the peritoneal cavity, fetal survival becomes extremely poor. Therefore, it is important for clinician to understand the uterine rupture and be able to give prompt treatment in order to prevent maternal and fetal morbidity and mortality. Case Presentation: A 34-year-old woman, G3P2A0 38 weeks of gestation complained that she had abdominal pain, couldn’t feel her baby movement, watery discharge since 10 hours before admission. Bloody discharge and trauma were all denied. Patient underwent twice cesarean section before. Patient only had four times antenatal care with obstetrician at 24, 28, 32, and 36 weeks of gestation. She was scheduled for caesarean section at 38 weeks of gestation. Patient looked alert with low blood pressure and tachycardia. On physical examination, we found that she was pale, fundal height could not be determined, and there was no fetal heart rate detected. Speculum examination showed livide portio, closed external orifice of uterus, and inactive blood. There was positive slinger sign and Douglas cavity was bulging. Ultrasound examination showed intrauterine fetal demise, complete uterine rupture on lower segment, and positive sign of free fluid on abdominal cavity. Patient underwent operation and we found the died male neonate was in the peritoneal cavity and the placenta was still attached in the uterine cavity. We delivered the baby and placenta completely. There was uterine rupture on the previous CS scar, the edge of the uterine wound was regular with no necrosis and extended to the right side of uterus. Then, we performed hysterorrhaphy in order to stop the bleeding and repair the uterus, and we also performed tubal ligation. The died neonate had maceration grade I. Conclusion: Uterine rupture causes poor fetal and maternal prognosis. Early diagnosis and prompt treatment is really important in uterine rupture. Prevention of uterine rupture could be done by meticulous antenatal care, especially visiting to obstetrician in order to review maternal and fetal condition and determine mode of delivery.

An Innovative Approach to Studying the State of the Uterine Scar after Cesarean Section on the Basis of a Comparative Study

Background. Today we have not really highly informative methods for assessing the state of the uterine scar. This fact does not allow us to formulate clear selection criteria for spontaneous delivery for patients who had cesarean section (CS). The result of the formulated problem is not only an increase in the frequency of repeated abdominal delivery, but also a fivefold increase in the risks of intraoperative and postoperative complications for women of reproductive age. Aims explore the property, structure and morphological features of the myometrial scar tissue by developing a physical model based on morphological predictors. Materials and methods. The study included 49 women who ahead a second caesarean section in the maternity hospital at the S.S. Yudin state medical center. The patients had scar tissue excised in the lower uterine segment and the resulting biopsies were divided into 2 fragments. The first fragment of biopsies was necessary for performing a morphological study, based on the results of which randomization was carried out into groups. The main group included 24 fragments, where the scar tissue was well-established, and the comparison group included 25 fragments, where according to morphological research, signs of its insolvency were revealed. Further assessment of the scar state was performed using the second fragment of biopsies by creating a physical model of the study, on the basis of which the dependence of elongation on the applied force was estimated. The study was conducted in the laboratory of scientific research on the development of bioprostheses of the CSSC A.N. Bakuleva. Results. Based on a morphological study, it was confirmed that the failure of the scar is based on the disorganization of connective tissue, indicating the possible presence of undifferentiated connective tissue dysplasia for the patient. The physical model of the study demonstrated that the presence of such a difficult-to-diagnose pathology leads to a decrease in the elasticity, and therefore-the strength and elasticity of the scar on the uterus. Conclusions. For this period of time, we need to improve methods for assessing the condition of the uterine scar in order to resolve the issue of the possibility of conducting natural childbirth for patients after undergoing CS surgery. It is possible that the created physical model will be able to evaluate the predictive ability of ultrasonic elastography within the framework of this problem. It is important to remember that scar formation is the final stage of regeneration, therefore, the maximum number of answers to a detailed study of morphological and immunohistochemical features of the myometrium, as it is the primary matrix on which will be the formation of scar tissue.

Role of Decapitation in Management of A Case of Complete Shoulder Dystocia with Rupture Uterus - A Case Report

Complete Shoulder dystocia in the presence of scarred uterus is an acute obstetrical emergency and if not properly handled can lead to serious fetal and maternal complications. A G5P4AO previous II cesarean sections, presented in emergency after delivery of fetal head and impacted shoulders, at a small private clinic in a village, four hours back. On laparotomy, there was uterine rupture from the previous uterine scar along with posterior bladder wall rupture . The shoulder dystocia was relieved by decapitation and breech extraction abdominally. Subtotal hysterectomy and repair of the bladder wall was done. This case highlight the dilemma of lack of regular antenatal care and maternal education, malpractices by untrained health professionals and time lapse in referral system that is still a very serious and major issue in developing countries like Pakistan .

Macrophage polarization in cesarean scar diverticulum

Aims: To determine immunohistochemical features and correlations between M1/M2 polarization status with disease severity of post-cesarean scar diverticulum（CSD）. Methods: Histological and immunohistological staining were performed and inflammatory (CD16, CD163, and TNF-α), fibrosis (α-SMA), and angiogenic (CD31) markers were examined in uterine tissues collected from patients with uterine scar diverticula (CSD) (n=37) and cesarean section (CS) (n=3). Results: CSD tissues have higher expression of α-SMA, TNF-α, CD16, and CD31 and lower expression of CD163 than CS tissue (P <0.05). Compared with adjacent tissues, thick-walled blood vessels, glands, and fibrotic sites have higher expression of α-SMA, TNF-α, and CD16. Statistical correlation was observed between the expression of CD16 and TNF-α (R = 0.693, P <0.001), α-SMA (R = 0.404, P <0.05), and CD31 (R = 0.253, P <0.05) in CSD tissues, especially with the ratio of CD16/CD163 (R = 0.590, P <0.01). A more significant difference was observed between the expression of CD16/CD163 and α-SMA (R = 0.556, P <0.001), TNF-α (R = 0.633, P <0.0001) and CD31 (R = 0.336, P <0.05) Statistical correlation. Conclusion: In this study, TNF-α, α-SMA, CD16, and CD31 proteins were overexpressed in all CSD cases, and CD16/CD163 was positively correlated with tissue inflammation, fibrosis, and neovascularization. Abnormal mononuclear macrophage infiltration may be involved in the origin and progression of CSD.

Myomectomy or conservative management of uterine fibroids: effects on reproductive potential

AIM: The aim of this study was to analyze reproductive function, pregnancy and labor in women after laparoscopic myomectomy and in women with unoperated myoma. MATERIALS AND METHODS: The main group consisted of 60 patients aged 25-46 years with a scar on the uterus who had laparoscopic myomectomy. Inclusion criteria were full-term pregnancy, uterine scar after laparoscopic myomectomy for subserosal or intramural uterine myoma (3-10 cm), and myomatous nodules (one to three). The comparison group included 30 women aged 25-46 years who were not surgically treated. Inclusion criteria were full-term pregnancy, subserosal or intramural uterine myoma (3-10 cm), and myomatous nodules (one to three). All patients in the main group underwent laparoscopic myomectomy. In all cases, the myomatous nodule was removed intracapsularly, leaving the leiomyoma pseudocapsule, which, with a deep arrangement of the transmural myomatous nodules, avoided opening the uterine cavity; myomatous nodule morcellation being used. With a deep intramural arrangement of the leiomyoma, the myometrial defect was sutured layer by layer with the application of several rows of endosutures. RESULTS: Six months after myomectomy, the patients underwent MRI of their pelvic organs with contrast. In 95% of cases, the uterine scar had no anatomical insolvency. In assessing the anamnesis, gynecological diseases occurred two times more often in women in the main group: 22 (36.7%) patients resorted to the use of the in vitro fertilization method for pregnancy, while among the patients in the comparison group, there were only two (6.7%) of them (2 = 12.8; р 0.001). In the main group, moderate preeclampsia and gestational diabetes mellitus were twice as common. In the main group, all patients were delivered by caesarean section, of which 83.3% were planned and 16.7% were emergency. In the comparison group, 73.3% of patients were delivered through the natural birth canal and 26.7% by caesarean section (2 = 149, p 0.0001). The most unfavorable signs predisposing to obstetric complications and operative delivery were the presence of multiple nodules (OR = 5.96 (1.09-32.72), p 0.05), the location of the nodule or scar in the uterine bottom (OR = 2.52 (1.00-6.33), p 0.05), and their combination with IVF (OR = 9.09 (2.42-34.07), р 0.01). CONCLUSIONS: In 95% of women, the scar on the uterus after myomectomy was consistent, but all these pregnant women were delivered by cesarean section, mainly for combined indications. However, they carried out the pregnancy safely, with a good outcome for the fetus. In women with uterine myoma and its conservative management, there was a lower rate of aggravated gynecological history and obstetric complications, and 73.3% of them were delivered through the natural birth canal. Despite the increased risk of caesarean section, the presence of uterine fibroids, even of a large size (more than 4 cm), should not be considered as a contraindication to vaginal delivery.

Diagnostic Accuracy of Lower Uterine Segment Scar Thickness ≤1.6mm in Prediction of Scar Dehiscence in patients

Background: Cesarean section uterine scar dehiscence (CSD) is a rare but notable complication of Lower segment cesarean section (LSCS) surgery. The cause for a uterine scar dehiscence is based on the etiology behind the uterine scar defect or any event that would predispose the cesarean scar to dehisce. Globally accepted option for assessing the CS scar is transvaginal ultrasonography of the non-pregnant uterus. Objective: To determine the diagnostic accuracy of lower uterine segment scar thickness≤1.6mm in the prediction of scar dehiscence in patients with previous one LSCS who are undergoing repeat LSCS after trial of labour taking intraoperative findings as gold standard. Material and methods: This cross sectional study was conducted in Services Hospital, Lahore for 6 months. The Non probability consecutive sampling technique was used to include women with previous one LSCS at 36-38 weeks were asked to get their TVS done for scar thickness. Women with scar thickness≤1.6mm and scar thickness>1.6mm were identified. Their intraoperative findings of scar dehiscence were confirmed. All the data was entered and analyzed on SPSS version 20. Results: The mean age of patients was 29.87±6.07 years. The emergency LSCS was done in 599(49.1%) patients and elective LSCS was done in 621(50.9%) patients. The sensitivity, specificity & diagnostic accuracy of TVS was 98.31%, 99.05% & 98.69% respectively. Conclusion: According to our study results the TVS for uterine scar is a very useful and effective tool in the prediction of scar dehiscence in patients with previous one LSCS taking intraoperative findings as gold standard.
