The Impact of Laparoscopic Myomectomy on Pregnancy Outcomes: A Systematic Review

STUDY OBJECTIVE

The objective of this systematic review is to investigate the impact of laparoscopic myomectomy techniques on pregnancy outcomes, with a specific focus on the correlation between the type of suture used during the procedure and the incidence of uterine rupture. Additionally, the study aims to examine how the localization and size of myomas, key factors in laparoscopic myomectomy, may influence fertility outcomes.

DATA SOURCES

extensive searches were conducted using MDPI, PubMed, Web of Science, and Cochrane Library databases from 2008 to November 2023.

METHODS OF STUDY SELECTION

The study involved women of reproductive age diagnosed with fibroids who underwent surgical removal of fibroids using either laparotomy or laparoscopy. The evaluation of pregnancy outcomes focused on indicators such as live birth rates, miscarriage rates, stillbirth rates, premature delivery rates, and cases of uterine rupture. Quality assessment was systematically performed by employing the National Institutes of Health Study Quality Assessment Tools, with the subsequent formulation of clinical recommendations that were meticulously graded in accordance with the robustness of the underlying evidence.

RESULTS

The pregnancy outcomes post-myoma treatment, as reflected in one of the presented tables, show a promising number of pregnancies and live births, but also indicate the potential risks of miscarriages and preterm births. The diversity in outcomes observed among various studies underscores the imperative for tailored patient care, as well as the necessity for additional research aimed at optimizing fertility and pregnancy outcomes following myoma treatment.

CONCLUSION

This study offers insights into the criteria for patient selection and intraoperative methodologies specifically related to laparoscopic myomectomy. To enhance our understanding of the associations between fibroid characteristics (location, size) and reproductive outcomes, additional research is warranted, particularly through well-designed clinical trials.

The Efficiency of a Uterine Isthmus Tourniquet in Minimizing Blood Loss during a Myomectomy-A Prospective Study

Background and Objectives: The objective of this study was to assess the effectiveness of using a peri-cervical tourniquet in reducing blood loss during a laparoscopic myomectomy. Materials and Methods: This prospective study evaluated the impact of performing a concomitant tourniquet placement during a laparoscopic myomectomy (LM). A total of 60 patients were randomly allocated to one of two groups: 30 patients who underwent an LM with a tourniquet placement (the TLM group) and 30 patients who benefited from a standard LM (the SLM group). This study's main objective was to evaluate the impact of tourniquet use on perioperative blood loss, which is quantified as the difference in the pre- and postoperative hemoglobin levels (Delta Hb) and the postoperative blood transfusion rate. Results: The mean Delta Hb was statistically lower in the TLM group compared to the SLM group: 1.38 g/dL vs. 2.41 g/dL (p < 0.001). The rate of postoperative iron perfusion in the TLM group was significantly lower compared to the SLM group (4 vs. 13 patients; p = 0.02). All four patients that required a blood transfusion were from the SLM group. On average, the peri-cervical tourniquet fastening time was 10.62 min (between 7 and 15 min), with no significant impact on the overall operative time: 98.50 min for the TLM group compared to 94.66 min for the SLM group. Conclusions: Fastening a tourniquet during a laparoscopic myomectomy is a valuable technique to effectively control intraoperative bleeding and enhance surgical outcomes.

Minimizing blood loss in laparoscopic myomectomy with temporary occlusion of the hypogastric artery

Introduction

Uterine leiomyomas are common benign pelvic tumors. Currently, laparoscopic myomectomy (LM) is the preferred treatment option for women in the fertile age group with symptomatic myomas. The authors hypothesize that combining LM with a bilateral temporary occlusion of the hypogastric artery (TOHA) using vascular clips minimizes uterine blood flow during surgery and can significantly reduce surgery-associated blood loss.

Materials and methods

This single-center, prospective randomized study was conducted at the Department of Obstetrics and Gynecology, Municipal Emergency Clinical Hospital Timisoara, Romania. Patients aged between 18 and 49 who preferred laparoscopic myomectomy and wished to preserve fertility were included, provided they had intramural uterine leiomyomas larger than 4 cm in diameter that deformed the uterine cavity. The study analyzed data from 60 laparoscopic myomectomies performed by a single surgeon between January 2018 and December 2020. Patients were randomly assigned to either: "LM + TOHA" group (29 patients), and "LM" group (31 patients). The study's main objective was to evaluate the impact of TOHA on perioperative blood loss, expressed as mean differences in Hb (delta Hb).

Results

Delta Hb was statistically lower in the "LM + TOHA" group compared to "LM" group, with mean ± standard (min-max): 1.68 ± 0.67 (0.39-3.99) vs. 2.63 ± 1.06 (0.83-4.92) g/dL, respectively (p < 0.001). There was a statistically significant higher need for postoperative iron perfusion in the "LM" group, specifically 0 vs. 12 patients (p < 0.001), and lower postoperative anemia in "LM + TOHA" group (p < 0.001). Necessary artery clipping time was 10.62 ± 2.47 (7-15) minutes, with no significant impact on overall operative time: 110.2 ± 13.65 vs. 106.3 ± 16.48 (p = 0.21). There was no difference in the length of hospitalization or 12-month post-intervention fertility.

Discussion

Performing bilateral TOHA prior to laparoscopic myomectomy has proven to be a valuable technique in reducing surgery-associated blood loss, while minimizing complications during surgery, with no significant increase in the overall operative time.

New Insights in the Diagnosis of Rare Adenocarcinoma Variants of the Cervix—Case Report and Review of Literature

We report the case of a 29-year-old patient with low-grade squamous intraepithelial lesion (L-SIL), negative human papilloma virus (HPV), positive p16/Ki-67 dual-staining and colposcopy suggestive for severe dysplastic lesion. The patient underwent a loop electrosurgical excision procedure (LEEP), the pathology report revealing mesonephric hyperplasia and adenocarcinoma. The patient also opted for non-standard fertility-sparing treatment. The trachelectomy pathology report described a zone of hyperplasia at the limit of resection towards the uterine isthmus. Two supplementary interpretations of the slides and immunohistochemistry (IHC) were performed. The results supported the diagnosis of mesonephric adenocarcinoma, although with difficulty in differentiating it from mesonephric hyperplasia. Given the discordant pathology results that were inconclusive in establishing a precise diagnosis of the lesion and the state of the limits of resection, the patient was referred to a specialist abroad. Furthermore, the additional interpretation of the slides and IHC were performed, the results suggesting a clear cell carcinoma. The positive p16/Ki-67 dual-staining prior to LEEP, the non-specific IHC and the difficulties in establishing a diagnosis made the case interesting. Given the limitations of cytology and the fact that these variants are independent of HPV infection, dual staining p16/Ki-67 could potentially become useful in the diagnosis of rare adenocarcinoma variants of the cervix, however further documentation is required.

Role of Dual-Staining p16/Ki-67 in the Management of Patients under 30 Years with ASC-US/L-SIL

Patients diagnosed with low-grade squamous intraepithelial lesion ((L-SIL) or atypical squamous cells of undetermined significance (ASC-US) are subjected to additional investigations, such as colposcopy and biopsy, to rule out cervical intraepithelial neoplasia 2+ (CIN 2+). Especially in young patients, lesions tend to regress spontaneously, and many human papilloma virus (HPV) infections are transient. Dual-staining p16/Ki-67 has been proposed for the triage of patients with ASC-US or L-SIL, but no prospective study addressing only this subgroup of patients has been conducted so far. We performed a prospective study including all eligible patients referred for a loop electrosurgical excision procedure (LEEP) in the Department of Obstetrics and Gynecology of Timișoara University City Hospital. HPV genotyping and dual-staining for p16/Ki-67 were performed prior to LEEP, at 6 and 12 months after LEEP. A total of 60 patients were included in the study and completed the follow-up evaluation. We analyzed the sensitivity and specificity for biopsy-confirmed CIN2+ using the 95% confidence interval (CI) of high-risk human papilloma virus (HR-HPV), dual-staining p16/Ki-67, colposcopy, and combinations of the tests on all patients and separately for the ASC-US and L-SIL groups. Dual-staining p16/Ki-67 alone or in combination with HR-HPV and/or colposcopy showed a higher specificity that HR-HPV and/or colposcopy for the diagnosis of biopsy confirmed CIN2+ in patients under 30 years. Colposcopy + p16/Ki-67 and HR-HPV + colposcopy + p16/Ki-67 showed the highest specificity in our study.

p16/Ki-67 dual staining has a better accuracy than human papillomavirus (HPV) testing in women with abnormal cytology under 30 years old

Due to a high rate of transient human papillomavirus (HPV) infection, HPV genotyping has a low specificity for high-grade cervical lesions, especially in young women. p16/Ki-67 dual immunocytochemical staining can also be used for the detection of oncogenic changes in cervical cells. Our aim was to compare the performance of p16/Ki-67 dual staining and HPV genotyping in the detection of high-grade cervical lesions in patients with atypical squamous cells of undetermined significance (ASCUS)/low-grade squamous intraepithelial lesion (LSIL) on Pap smear. We retrospectively analyzed 310 patients with ASCUS/LSIL on Pap smear, who underwent colposcopy. Among these, 161 patients with suspected lesions detected by colposcopy were referred for biopsy. HPV genotyping by LINEAR ARRAY HPV Genotyping Test (CE-IVD) and p16/Ki-67 dual staining by CINtec PLUS Cytology kit was performed prior to cervical biopsy. The overall sensitivity and specificity of HPV genotyping for the detection of cervical intraepithelial neoplasia (CIN) 2-3 was 79% and 72%, respectively in patients with ASCUS, and 85% and 64%, respectively in patients with LSIL. For p16/Ki-67 test, sensitivity and specificity rate was 66% and 93%, respectively in ASCUS and 59% and 79%, respectively in LSIL group. The specificity of p16/Ki-67 staining was significantly higher in both groups in patients aged <30 years compared to patients >30 years old (p < 0.001). Our results showed that p16/Ki-67 dual staining has a higher specificity compared to HPV genotyping, especially in patients under 30 years old. This indicates the usefulness of p16/Ki-67 testing in the triage of patients with ASCUS/LSIL and <30 years old, prior to referral for colposcopy and biopsy.

Clinical and Histopathological Parameters Correlate with Microvessel Density but Not with Vascular Endothelial Growth Factor Expression in Ovarian Cancer

Ovarian cancer malignancies have the worst prognosis among all gynecological malignancies. As angiogenesis represents a key step for tumor progression, vascular endothelial growth factor (VEGF) is one of the most discussed pro-angiogenic factors. VEGF expression was investigated in 62 cases of ovarian carcinomas. Microvessel density (MVD) was evaluated by correlating the results with clinical and histopathological parameters. Because of the controversial results reported in other studies, VEGF was assessed together with MVD. Our results suggest a more complex angiogenic mechanism in ovarian cancer based on the discrepancies between VEGF expression, microvessel density and their correlation with clinical parameters. The conflicting data arising from this study supports the implications of different growth factors, others than VEGF in ovarian cancer. This hypothesis is sustained by the lack of correlation between VEGF and clinical parameters, and by the significant correlation between microvessel density and clinicopathological parameters. Thus, further studies are needed for a complete evaluation of angiogenesis in ovarian cancer.

Laparoscopic Resection of Cesarean Scar Ectopic Pregnancy after Unsuccessful Systemic Methotrexate Treatment

STUDY OBJECTIVE

To present a case of a cesarean scar ectopic pregnancy treated by laparoscopic resection followed by isthmocele repair.

DESIGN

A case report.

SETTINGS

The University Gynecology Clinic of the Emergency Clinical City Hospital Timișoara, Timișoara, România.

BACKGROUND

Cesarean scar pregnancy is a rare form of ectopic pregnancy. In recent years, its prevalence has risen because of the increasing number of cesarean sections. An early diagnosis can lead to early management, decreasing the risk of life-threatening complications such as uterine rupture and massive hemorrhage. Many therapeutic options are available, medical and surgical, but the current literature suggests that the laparoscopic approach with ectopic pregnancy resection is the best option.

CASE REPORT

We present the case of a 30-year-old woman with a previous cesarean section in 2012 who was diagnosed by transvaginal ultrasound with a 6-week live pregnancy implanted at the level of the cesarean scar. The initial management was the administration of a 2-dose methotrexate protocol, but after 72 hours the transvaginal ultrasound showed an embryo with cardiac activity still present associated with an increased beta human chorionic gonadotropin level. We decided on laparoscopic surgical treatment, aiming to extract the pregnancy and repair the scar defect. A similar case was presented by Mahgoub et al [1], but their case had a different evolution, with decreasing levels of hCG.

INTERVENTIONS

In order to reduce the blood loss, the anterior trunks of the hypogastric arteries were clipped. The side wall peritoneum was cut bilaterally, and the ureters and the hypogastric arteries were dissected. Next, we performed the dissection of the vesicouterine space. Because of the previous cesarean section, the identification of the correct dissection plane was difficult. A uterine manipulator was used to facilitate the dissection. The exact location of the gestational sac was demonstrated using intraoperative transvaginal ultrasound. To reduce the bleeding, Glypressin (Ferring GmbH, Saint Prex, Switzerland) was injected at the level of the uterine scar. The cesarean scar was cut using a monopolar knife. The gestation sac was reached easily and then extracted from the abdominal cavity with the use of an endobag. In order to obtain proper healing, the margins of the scar were resected using cold scissors. The hysterotomy was closed using a double-layered suture with 2.0 Vicryl (Ethicon Inc., Cincinnati, OH). We used methylene blue to verify the tightness of the suture. The final step was the removal of the clips.

MEASUREMENTS AND MAIN RESULTS

The operative time was 85 minutes with minimal blood loss of about 20 mL. The patient recovered well and was discharged 2 days after the procedure. A transvaginal ultrasound was performed 1 month after the surgery showing good healing of the anterior uterine wall.

CONCLUSION

The laparoscopic approach with excision and repair of the uterine wall represents a safe and efficient therapeutic option for the treatment of the cesarean scar ectopic pregnancy.

Laparoscopic Promontohysteropexy During Pregnancy

STUDY OBJECTIVE

To present a case of uterine prolapse in a pregnant patient at 10 weeks of gestation who was successfully treated by laparoscopic promontohysteropexy. To our knowledge, this is the first case of laparoscopic promontopexy during pregnancy to be reported in the literature.

DESIGN

Step-by-step description of the surgery using videos (Canadian Task Force classification 3).

SETTING

Uterine prolapse is a rare condition in young patients and is extremely rare in pregnant women. The reported incidence of uterine prolapse during pregnancy is 1/10,000 to 15,000 deliveries [1]. To date, only a few cases of prolapse during pregnancy have reported in the literature, most of which were treated with pessary insertion. A case involving laparoscopic surgery for uterine prolapse during pregnancy was reported by Matsumoto et al 1999 [2], but the authors did not perform the promontohysteropexy technique.

INTERVENTION

A 27-year-old patient with uterine prolapse at 10 weeks of gestation was referred to our clinic for severe pelvic pain. Conservative treatment with pessary insertion was attempted but failed. Consequently, the patient was scheduled for laparoscopic promontohysteropexy. The surgery was made difficult by the increased size and softness of the uterus. To create an adequate surgical field, the sigmoid colon and right adnexa were suspended at the abdominal wall. The peritoneum above the promontorium was incised, and the longitudinal ligament was dissected. The paravesical spaces were opened, and the vesicovaginal space was dissected. A polypropylene mesh in the shape of an inverted "T" was introduced. The small arm was sutured to the anterior vaginal wall, and the posterior arms were passed through the posterior leaves of the broad ligament and fixed to the cervix at the level of the uterosacral ligaments. Both posterior arms were fixed at the level of the promontory using the Protack device (Medtronic, Minneapolis, MN). The mesh was completely covered with peritoneum. The patient was discharged 3 days after surgery, with no pain and with normal pelvic floor status. The pregnancy proceeded uneventfully, and she delivered a 3500-g healthy baby by scheduled cesarean section at 39 weeks of gestation. During surgery, the position of the mesh around the uterus was assessed. The mesh was completely covered with peritoneum, and there were no adhesions due to mesh insertion. At 6 months after delivery, pelvic floor status was reassessed and found to be normal. Written informed consent for reporting this case was obtained from the patient before the procedure. The procedure was performed in accordance with the ethical standards laid down in the 1964 Declaration of Helsinki and its later amendments. The Institutional Review Board and Ethical Committee of Victor Babeş University of Medicine and Pharmacy ruled that approval was not required for this study.

CONCLUSION

Laparoscopic promontohysteropxy can be performed during pregnancy if conservative treatment, such as pessary insertion, fails to restore the normal pelvic floor status.

Early pregnancy serum neopterin concentrations predict spontaneous preterm birth in asymptomatic pregnant women

OBJECTIVE

To investigate if early pregnancy serum neopterin concentrations (EPSN) could predict spontaneous preterm birth (SPB).

METHODS

EPSN was measured in 92 sera collected from 46 pregnant women with birth at term and 40 sera from 20 pregnant women with preterm birth. Two sera were collected for each case: in the first and early second trimester.

RESULTS

EPSN concentrations correlate with gestational age (ρ=0.275, P=0.001), a correlation which was present in both groups: term and preterm birth. EPSN were higher in pregnancies with SPB compared with normal pregnancies (6.27±1.03 vs. 6.04±0.15, P=0.039). Patients with SPB showed a considerable increase of EPSN in the second trimester compared with patients with birth at term (7.30±1.53 vs. 6.16±0.23, P=0.043). A sharper increase was found in the group with SPB before 32 weeks of pregnancy (wp) (9.83±4.36 vs. 6.16±0.23, P=0.016). Pregnant women with an early second trimester serum neopterin value of above 8 nmol/L are associated with a risk of SPB before 32 wp (odds ratio=14.4, P=0.01) and of SPB before 34 wp (odds ratio=3.6, P=0.05), respectively.

CONCLUSIONS

EPSN increases with the gestational age and predicts SPB in asymptomatic pregnant women.

Endothelial progenitor cells contribute to the development of ovarian carcinoma tumor blood vessels

Only a few studies in the literature have reported the contribution of endothelial progenitor cells (EPCs) in ovarian tumors, and with regard to malignant tumors, the data on the pre-existing endothelium insertion rate and the extent to which these cells contribute to tumor angiogenesis is controversial. The present study demonstrated the existence of EPCs and evaluated the expression of two markers, AC133 (also known as cluster of differentiation 133 or prominin) and tyrosine kinase with immunoglobulin-like and EGF-like domains 2 (Tie2), signaling the presence of EPCs in the pre-existing endothelium. In total, 62 female patients who were diagnosed with ovarian tumors were retrospectively selected over a four-year period. Immunohistochemical analyses used Tie2 and AC133 as primary antibodies. In total, 27.4% of ovarian tumor cases expressed AC133 and Tie2 in blood vessel endothelial cells. The expression of these two markers did not correlate with the clinicopathological prognostic parameters, histological type, vascular microdensity or vessel type. The expression of AC133 and Tie2 in blood vessel endothelial cells contributes to angiogenesis progression in cases where the budding process is reduced or absent, as shown by the inverse correlation with the rate of proliferation of the endothelial cells.

Treatment of complete genital prolapse by sacrospinous fixation, anterior mesh repair and conservation of the uterus

The surgical treatment of complete genital prolapse must aim the restoration of the vaginal support structures. All 3 levels of the vaginal support system must be recreated. Ablation of the uterus is not useful for pelvic floor support. Sparing of the uterus offers the advantage of a reduced surgical trauma, and better pelvic floor restoration. We present the case of a 60-year old woman with complete genital prolapse where the uterus was spared, and sacrospinous fixation, anterior mesh repair,perineal body repair and suburethral sling insertion were performed. The results were very good, by means of pelvic floor statics and physiology of micturition.

CONCLUSION

genital prolapse must be cured by reconstruction of the vaginal support system, not by hysterectomy.

Meningococcal septic shock after IUD insertion, a case presentation

Neisseria meningitidis is a normal commensal of human mucous membranes that is no longer considered to be restricted to the nasopharynx. Due to the practice of oral sex, the mucous membranes of the cervix, urethra or anus have become a potential infection site for this bacterium. Inserting an intrauterine device (IUD), can alter the protective barrier of the endocervical mucosa, allowing for bacterial infection and systemic spread. We present a case report of a 40-year-old woman who presented with abdominal pain, spotting and fever after inserting an IUD and developed a fulminant septic shock. Blood cultures and cultures from ascites showed the presence of Neisseria meningitidis group Y. From our knowledge, there are a few cases presented in the literature of toxic shock syndrome after IUD insertion, caused by Staphylococcus aureus or Streptococcus group A, but this is the first case of meningococcal sepsis after IUD insertion described. So, even though IUDs rarely cause significant infection, physicians should consider this device as a possible source in reproductive-age women with the clinical features of sepsis.

Unusual localisation of an ectopic pregnancy

We present a case of ectopic pregnancy with a peculiar localisation: beneath the peritoneal serosa covering the anterior wall of the uterus, at the level of the uterovesical pouch. The case raised some diagnostic and management problems for the medical team. Considerations are made concerning the etiopathology of this unusual form of ectopic pregnancy.
