A randomized controlled trial of 2 techniques of salpingectomy during cesarean delivery.

BACKGROUND: Total salpingectomy during benign gynecologic surgery is recommended after completion of childbearing to reduce the risk of developing ovarian cancer. OBJECTIVE: This study aimed to assess operating time and complication rates of "traditional" salpingectomy using the "Knot and Cut" technique, compared with bipolar salpingectomy for sterilization at the time of cesarean delivery. STUDY DESIGN: This was a randomized controlled trial. Women undergoing planned cesarean delivery who desired sterilization were randomized to traditional salpingectomy or bipolar salpingectomy. The bipolar salpingectomy was performed using the LigaSure Precise. The primary outcome was the surgical time of the salpingectomy procedure. Secondary outcomes included total cesarean delivery time and associated bleeding parameters. We estimated that 42 patients would provide 80% power and a 2-sided alpha of 0.05 to identify a 10-minute difference in the primary outcome. RESULTS: A total of 26 women were randomized to bipolar salpingectomy and 25 to traditional salpingectomy. Baseline demographic characteristics were similar between the groups. Six procedures were converted from traditional to bipolar salpingectomy, and 2 traditional salpingectomies failed. The surgical time (16.16±9.53 vs 5.19±3.57 minutes; P<.001), estimated blood loss (928.08±414.66 mL vs 677.15±380.42 mL; P=.029), and need for blood transfusion (20% vs 0%; P=.016) were significantly greater in the traditional salpingectomy than in the bipolar salpingectomy group. The cesarean delivery time was similar (88.92±17.87 vs 88.23±19.85 minutes; P=.89). Hospitalization time was significantly longer following traditional salpingectomy than bipolar salpingectomy (5.24±2.27 vs 3.92±2.01 days; P=.034). CONCLUSION: "Traditional" salpingectomy is associated with longer surgical and hospitalization time, and greater blood loss and risk of blood transfusion compared with "bipolar" salpingectomy. In practices in which "bipolar" salpingectomy is available, it should be preferred over alternative methods of salpingectomy.

Transvaginal Natural Orifice Transluminal Endoscopic Uterosacral Ligament Hysteropexy: An Innovative Approach for Treatment of Uterine Prolapse.

STUDY OBJECTIVE: Transvaginal natural orifice transluminal endoscopic surgery (vNOTES) was previously described as a feasible approach to perform several procedures including hysterectomy followed by uterosacral ligament suspension [1,2]. Approaching the cul-de-sac with vNOTES while the uterus is intact allowing access to the uterosacral ligaments. This enables attainment of apical support by placing sutures on the ligaments, shortening them, and reinforcing their attachment to the cervix. The objective of this video is to demonstrate a surgical technique for vNOTES uterosacral ligament hysteropexy (ULH). DESIGN: Stepwise demonstration of the technique with narrated video footage. This video report is part of an institutional, investigational review board-approved study. SETTING: Academic tertiary referral center. INTERVENTIONS: This video presents our team's vNOTES technique for ULH in a woman aged 37 years (gravida 3 para 3) who presented with pelvic organ prolapse quantification stage 3 symptomatic uterine prolapse. The patient requested uterine prolapse repair surgery while retaining the uterus. After performing a posterior colpotomy and entering the posterior cul-de-sac, the alexis and then the GelPOINT V-path transvaginal access platform (Applied Medical, Rancho Santa Margarita, CA) were placed into the vagina. Three trocars were inserted into the port. We used a 10-mm scope with a 30°-angle view. The instruments included a needle driver and a clinch grasper. The next step was to identify the uterosacral ligamentous structures. Once identified, 2 absorbable vicryl sutures and 1 nonabsorbable Ti-cron suture were placed on each ligament and then secured with large bites into the junctional portion of the uterosacral ligament with the posterior aspect of the cervix. The GelPOINT was then extracted, and the sutures locked in place to shorten the uterosacral ligaments and reinforce their attachment to the cervix. After all the suspensory sutures were tied, cystoscopy was performed to assess ureteral patency. The vaginal incision was then reapproximated in a horizontal manner, using continuous absorbable suture. CONCLUSION: vNOTES ULH appears to be feasible in women with uterine prolapse when uterus conservative treatment is desired. Advantages of this technique include good exposure of the ureter, lowering the risk of ureteric injury. In addition, the absence of incisions on the abdomen eliminates the risk of abdominal wound infection and incisional pain and yields a better cosmetic outcome. Further studies are needed to appraise the long-term outcomes and demonstrate the ultimate use of this modality.

Transvaginal natural orifice transluminal endoscopic versus conventional vaginal hysterectomy with uterosacral ligament suspension for apical compartment prolapse.

OBJECTIVE: The objective of this study was to compare surgical and short-term postoperative outcomes of transvaginal natural orifice transluminal endoscopic surgery (vNOTES) versus conventional vaginal (CV) uterosacral ligament suspension (USLS) surgery. STUDY DESIGN: A retrospective cohort study was conducted on 135 patients who underwent hysterectomy with USLS via CV (n = 70) or via vNOTES (n = 65). Patients' baseline characteristics, surgical characteristics, and surgical outcomes were retrieved. The primary outcome was total operative time. Secondary outcomes include intra- and post-operative complications. RESULTS: Salpingectomy was performed in all vNOTES procedures and in only 27 % of conventional vaginal procedures (p < 0.005). Compared to the conventional vaginal procedures (n = 65), the vNOTES (n = 70) showed lower mean operative time and mean anesthesia time (101.4 ± 22.3 vs 125.5 ± 27.6 min and 141.4 ± 29.6 vs. 174.0 ± 32.9 min, respectively); and slightly longer median hospital stay (3 [range 2-4] vs. 2 [range 2-4] days, p < 0.05). Compared to women who underwent conventional vaginal hysterectomy with USLS, women who underwent vNOTES hysterectomy with USLS had lower incidences of intraoperative complications (6% vs. 18 %, p < 0.05) and intraoperative ureteral obstruction (0% vs. 8%, p < 0.05); and less estimated blood loss (58 ± 68 ml vs. 143 ± 87 ml, p < 0.05). CONCLUSION: vNOTES hysterectomy with USLS is associated with reduced incidence of intraoperative complications, shorter surgical and anesthesia time, and slightly longer hospital stay, compared to the traditional vaginal surgical approach. Post-operative complications during hospital stay were similar and infrequent following the two procedures.

Feasibility and Learning Curve of Transvaginal Natural Orifice Transluminal Endoscopic Surgery for Hysterectomy and Uterosacral Ligament Suspension in Apical Compartment Prolapse.

OBJECTIVE: The aim of this study was to describe our experience with transvaginal natural orifice transluminal endoscopic surgery (vNOTES) uterosacral ligament suspension (USLS) and to evaluate the learning curve of mastering the skills to operate this procedure. METHODS: This is a prospective study of the first 35 vNOTES hysterectomy and USLS surgeries performed between October 2018 and April 2019 at Rambam Health Care Campus (Israel) (n = 26) and Imelda Hospital (Belgium) (n = 9). The primary outcome was surgical time. Secondary outcomes included intraoperative bleeding, length of hospitalization, pain during the first 24 hours postoperative pain, and the need for analgesia, intraoperative, and postoperative adverse events. RESULTS: The median age was 55 years (range, 40-81). The median operative time was 113 minutes (range, 89-233). For the procedures performed at Rambam, total operative time decreased from the first 13 to the following 13: from 149 minutes (range, 89-233 minutes) to 103 (89-170) (<0.001); Pearson correlation demonstrated a moderate negative significant correlation of surgery duration with surgeon experience (rho = -0.445, P < 0.001). The median estimated blood loss was 30 mL (20-200). The median hospital stay was 2 days (1-3). There were no intraoperative adverse events. The median visual analogue scale score for pain assessment during the first 24 hours after surgery was 1 (range, 1-3). CONCLUSIONS: vNOTES USLS is a feasible procedure that showed marked improvement in surgical performance in a short period, as evidenced by the decrease in surgical time and the low rate of minor associated perioperative complications. Outcomes of long-term follow-up should be investigated.

Robotic Vaginal Natural Orifice Transluminal Endoscopic Hysterectomy for Benign Indications.

STUDY OBJECTIVE: The Hominis surgical system is a novel robot-assisted system, designed specifically for robotic vaginal natural orifice transluminal endoscopic surgery (RvNOTES). We presented our experience of the first 30 RvNOTES hysterectomies assessing the feasibility and safety of this technology. DESIGN: A two-center prospective study. SETTING: Academic tertiary referral centers. The ethics committees approved the study in both centers. PATIENTS: Thirty women with benign indication for hysterectomy. INTERVENTION: RvNOTES hysterectomy performed by the Hominis surgical system. MEASUREMENTS AND MAIN RESULTS: The primary outcome of the study was the rate of conversion to open or conventional laparoscopic approaches. Secondary outcomes included intra- and postoperative adverse events, operative time, estimated blood loss, length of hospital stay, and 6-week follow-up assessment. A total of 15 women were enrolled at each site. The median age was 59 years (range: 37-79) and the median body mass index was 25.4 kg/m2 (range: 17.6-40.0). Twenty-four women (80%) had comorbidities. All the procedures were completed successfully without conversion to open abdominal, traditional vaginal, or conventional laparoscopic surgery. No intraoperative complications were observed. Median blood loss and procedure duration were 50 mL (range: 20-400) and 57 minutes (range: 24-88), respectively. Postoperative pain was minimal, with a median visual analog scale of 3 (range: 1-5) for the first 24 hours following surgery. The median hospital stay was 3 days (range: 2-8). According to the treating physicians' evaluations, the vaginal cuff was fully healed in all patients at the 6-week postoperative follow-up visit. CONCLUSIONS: This is the first publication of robot-assisted vaginal hysterectomy using the Hominis surgical system. The positive results of this study show this new technology to be a safe and effective tool for vaginal natural orifice transluminal endoscopic surgery, enabling surgeons to operate vaginally with the known advantages of robotic modality.

Cerebral Palsy-Trends in Epidemiology and Recent Development in Prenatal Mechanisms of Disease, Treatment, and Prevention.

Cerebral palsy (CP) is the most common motor disability in childhood. This syndrome is the manifestation of intrauterine pathologies, intrapartum complications, and the postnatal sequel, especially among preterm neonates. A double hit model theory is proposed suggesting that an intrauterine condition along with intrapartum or postnatal insult lead to the development of CP. Recent reports demonstrated that treatment during the process of preterm birth such as magnesium sulfate and postnatal modalities such as cooling may prevent or reduce the prevalence of this syndrome. Moreover, animal models demonstrated that postnatal treatment with anti-inflammatory drugs coupled with nanoparticles may affect the course of the disease in pups with neuroinflammation. This review will describe the changes in the epidemiology of this disease, the underlying prenatal mechanisms, and possible treatments that may reduce the prevalence of CP and alter the course of the disease.

Early onset preeclampsia and cerebral palsy: a double hit model?

BACKGROUND: Cerebral palsy (CP) is a late sequel of pregnancy, and the role of preeclampsia is debatable. OBJECTIVE: The aims of this study were to determine the association between preeclampsia and cerebral palsy and to determine the risk factors for the development of cerebral palsy in these patients. STUDY DESIGN: A retrospective population-based cohort study was designed that included 229,192 singleton pregnancies. The study population was divided into 2 groups: (1) patients with preeclampsia (n = 9749) and (2) normotensive gestations (n = 219,443). Generalized Estimating Equation multiple logistic regression models were performed to study the associations among preeclampsia, small for gestational age, gestational age at delivery, and the risk factors for the development of cerebral palsy in neonates of women with preeclampsia. RESULTS: The rate of cerebral palsy was double in patients with preeclampsia than in the normotensive group (0.2% vs 0.1%; P = .015); early onset preeclampsia and small for gestational age were independent risk factors for the subsequent development of cerebral palsy (odds ratio, 8.639 [95% confidence interval, 4.269-17.480]; odds ratio, 2.737 [95% confidence interval, 1.937-3.868], respectively). A second model was conducted to determine the risk factors for the development of cerebral palsy in women with preeclampsia. Birth asphyxia, complications of prematurity, and neonatal infectious morbidity, but not small for gestational age or gestational age at delivery, were independent risk factors for the development of cerebral palsy. CONCLUSION: In a comparison with normal pregnant women, the rate of cerebral palsy is double among patients with preeclampsia, especially those with early-onset disease. Early-onset preeclampsia is an independent risk factor for cerebral palsy. Among women with preeclampsia, the presence of neonatal infectious morbidity, birth asphyxia, and complications of prematurity are independent risk factors for the development of cerebral palsy, which further supports the role of a multi-hit model in the pathogenesis of this syndrome.

Metachromasy as an indicator of photostabilization of methylene blue adsorbed to clays and minerals.

The influence of methylene blue adsorption to different clays on its photodegradation was studied. Methylene blue in solution was decomposed by sunlight in a zero-order process. Adsorption to some clay minerals (sepiolite and vermiculite) and a zeolite (clinoptilolite) accelerated the degradation process, and converted it to a first-order reaction. On the other hand, adsorption to other clay minerals (palygorskite and montmorillonite) stabilized the dye and prevented its degradation. Interestingly, in the clay-dye complexes that exhibited stability, clear metachromasy of the adsorbed methylene blue occurred, whereas the effect was not observed in the clay-dye complexes that underwent photodegradation.
