Laparoscopic Excision of Cesarean Scar Pregnancy with Scar Revision.

OBJECTIVE: To demonstrate our technique for robot-assisted laparoscopic ectopic pregnancy excision and concomitant scar revision. DESIGN: We present a stepwise narrated demonstration of our primary laparoscopic technique. SETTING: Although cesarean scar pregnancy is rare, it leads to life-threatening complications and often emergent hysterectomy [1,2]. Because of its rarity, there is a scarcity of centers with high-volume experience with its treatment, and no standardized diagnostic or management guidelines are yet available [3,4]. Recent evidence suggests that primary surgical management may be superior to medical or radiologic management as the latter methods carry a high reintervention rate [5]. An additional consideration in selecting a treatment method is a patient's plans for future fertility, as cesarean scar defects are associated with secondary infertility. Evidence shows that repair of cesarean scar defects decreases the likelihood of future recurrence and secondary infertility, thus it may be pertinent to select a management strategy that allows for the accomplishment of both ectopic pregnancy removal and defect revision. We present our primary laparoscopic approach to ectopic pregnancy excision and revision of the cesarean scar defect using techniques rooted in evidence and robust experience. INTERVENTIONS: Robot-assisted laparoscopic excision of a cesarean scar ectopic pregnancy with concomitant scar revision demonstrating key strategies to minimize blood loss and preserve future fertility. (1) A laparoscopic approach allows for concomitant ectopic pregnancy removal followed by cesarean scar revision. (2) Generous use of dilute vasopressin and purposeful application of electrosurgical energy provides hemostasis without the use of more invasive measures such as vascular clips or uterine artery balloons. (3) A multilayer closure is associated with a lower risk of wedge defect formation and uterine rupture. (4) Diagnostic hysteroscopy is a useful tool for identifying the location of the scar defect, assessing for an adequate repair, and identifying potential additional uterine pathology. CONCLUSION: Primary laparoscopic management is not only the most effective method with the lowest complication rates but is an approach that allows for simultaneous repair and revision of the cesarean scar defect. We demonstrate easily adaptable techniques for maintaining hemostasis, minimizing injury to normal myometrium, and creating multilayer closures that lead to successful revisions with minimal impact to subsequent fertility.

Resectoscopic Surgery for Polyps and Myomas: A Review of the Literature.

Resectoscopic surgery is routinely performed to remove endometrial polyps and uterine myomas. A search of Medline, PubMed, and the Cochrane Library was conducted through November 2016 for studies written in English, regardless of sample size or study type. The studies were then filtered by selecting those evaluating resectoscopic surgery. An analysis of peer-reviewed, published literature was performed to examine the clinical application of this treatment modality on patients requiring polypectomy and myomectomy. Different surgical techniques were also compared: hysteroscopy with scissors, forceps, or a cold loop; resectoscopy with radiofrequency energy; and mechanical resection. The literature finds that operative time during resectoscopic surgery is significantly longer than with mechanical resection. Resectoscopic myomectomy, however, may be necessary for removal of larger or more deeply embedded myomas. Ultimately, both techniques result in symptom resolution and a low recurrence rate.

The minimally invasive approach to the symptomatic isthmocele - what does the literature say? A step-by-step primer on laparoscopic isthmocele - excision and repair.

PURPOSE OF REVIEW: The purpose of this review is to understand the minimally invasive approach to the excision and repair of an isthmocele. RECENT FINDINGS: Previous small trials and case reports have shown that the minimally invasive approach by hysteroscopy and/or laparoscopy can cure symptoms of a uterine isthmocele, including abnormal bleeding, pelvic pain and secondary infertility. A recent larger prospective study has been published that evaluates outcomes of minimally invasive isthmocele repair. Smaller studies and individual case reports echo the positive results of this larger trial. SUMMARY: The cesarean section scar defect, also known as an isthmocele, has become an important diagnosis for women who present with abnormal uterine bleeding, pelvic pain and secondary infertility. It is important for providers to be aware of the effective surgical treatment options for the symptomatic isthmocele. A minimally invasive approach, whether it be laparoscopic or hysteroscopic, has proven to be a safe and effective option in reducing symptoms and improving fertility.

Power Morcellation Using a Contained Bag System.

BACKGROUND AND OBJECTIVES: The well-known advantages of minimally invasive surgery make the approach well suited for hysterectomy and other gynecological procedures. The removal of specimens excised during surgery has been a challenge that has been answered by the use of power morcellation. With this study we sought to assess the feasibility of power morcellation within a specimen bag. METHODS: This was a retrospective cohort study including patients from a private practice in suburban Chicago, Illinois, who underwent contained electromechanical power morcellation during a laparoscopic or robot-assisted hysterectomy or myomectomy from May 2014 through December 2015. Contained power morcellation was performed with the Espiner EcoSac 230 (Espiner Medical Ltd., North Somerset, United Kingdom) specimen bag. Descriptive statistics were performed for both categorical and continuous data. RESULTS: Of the 187 procedures performed, 73.8% were myomectomies, and 26.2% were hysterectomies. The patients' mean age was 40 (range, 25-54) years and mean body mass index was 28.7 (range, 17.3-57.6). The average specimen weight was 300 g, with the largest weighing 2134 g. Estimated blood loss averaged 98.4 mL. The postoperative admission rate was 12.3%, most of which were due to nausea and urinary retention. Seventeen patients (9.1%) had postoperative complications, most of which were minor, and 4 (2.1%) were readmitted. There were no bag failures or complications that were due to the use of the specimen bag or to power morcellation. CONCLUSIONS: Performing electromechanical power morcellation within the Espiner EcoSac 230 specimen bag was successfully performed in 187 patients with no bag-related complications. This method of contained power morcellation is feasible, reliable, and reproducible, even for a large specimen.

Hysteroscopy safety.

PURPOSE OF REVIEW: Hysteroscopy is a very common tool providing the gynecologist the ability to diagnose and treat a variety of intrauterine disorders. This outpatient therapy has provided quick and effective relief for women worldwide. Although simple in concept, hysteroscopy is associated with minor and major complications. Awareness of these difficulties and methods of prevention and management is key to good surgical outcomes. This article reviews well tolerated practices for hysteroscopy complications. RECENT FINDINGS: Although complications with both diagnostic and operative hysteroscopy are rare, they can often be prevented with thorough preoperative evaluation and appropriate intraoperative decision making. Understanding the patient, disorder, and surgical process can assist the surgeon in providing the best outcome for the patient. SUMMARY: With appropriate training and education, gynecologists can safely incorporate hysteroscopy into their surgical practice.

Hysteroscopy for infertile women: a review.

Hysteroscopy is widely performed in infertile women. A review of peer-reviewed, published literature from the PubMed database on uterine intracavitary pathology, proximal tubal occlusion, failed in vitro fertilization procedures, and first trimester miscarriages of infertile women was performed to examine the importance, feasibility, and success rates of diagnostic and operative hysteroscopy when evaluating and treating these conditions.

Persistent bleeding after laparoscopic supracervical hysterectomy.

BACKGROUND AND OBJECTIVES: In our clinical experience, there seemed to be a correlation between cervical stump bleeding and adenomyosis. Therefore, we wanted to conduct a study to determine whether there was an actual correlation and to identify other risk factors for persistent bleeding after a laparoscopic supracervical hysterectomy. METHODS: The study included women who underwent laparoscopic supracervical hysterectomy from January 1, 2003, through December 31, 2012. Data were collected on age, postmenopausal status, body mass index (BMI), uterine weight, indication for hysterectomy, concomitant bilateral salpingo-oophorectomy (BSO), presence of endometriosis, surgical ablation of the endocervix, adenomyosis, presence of endocervix in the specimen, and postoperative bleeding. RESULTS: The study included 256 patients, of whom 187 had no postoperative bleeding after the operation, 40 had bleeding within 12 weeks, and 29 had bleeding after 12 weeks. The 3 groups were comparable in BMI, postmenopausal status, uterine weight, indication for hysterectomy, BSO, surgical ablation of the endocervix, adenomyosis, and the presence of endocervix. However, patients who had postoperative bleeding at more than 12 weeks were significantly younger (P = .002) and had a higher rate of endometriosis (P < .001). CONCLUSIONS: Risks factors for postoperative bleeding from the cervical stump include a younger age at the time of hysterectomy and the presence of endometriosis. Therefore, younger patients and those with endometriosis who desire to have no further vaginal bleeding may benefit from total hysterectomy over supracervical hysterectomy. All patients who are undergoing supracervical hysterectomy should be counseled about the possible alternatives, benefits, and risks, including continued vaginal bleeding from the cervical stump and the possibility of requiring future treatment and procedures.

Adnexal torsion: review of the literature.

Adnexal torsion is one of a few gynecologic surgical emergencies. Misdiagnosis or delay in treatment can have permanent sequelae including loss of an ovary with effect on future fertility, peritonitis, and even death. A PubMed search was performed between 1985 and 2012 for reviews, comparative studies, and case reports to provide a review of the epidemiology, risk factors, clinical presentation, common laboratory and imaging findings, and treatments of adnexal torsion. Common symptoms of torsion include pain, nausea, and vomiting, with associated abdominal or pelvic tenderness, and may differ in premenarchal and pregnant patients. Laboratory and imaging findings including ultrasound with Doppler analysis, computed tomography, and magnetic resonance imaging can assist in making the diagnosis but should not trump clinical judgment; normal Doppler flow can be observed in up to 60% of adnexal torsion cases. Treatment depends on the individual patient but commonly includes detorsion, even if the adnexae initially seem necrotic, with removal of any associated cysts or salpingo-oophorectomy, because recurrence rates are higher with detorsion alone or detorsion with only cyst aspiration.

Gonadotropin-releasing hormone/gonadotropin-releasing hormone receptor signaling in the placenta.

PURPOSE OF REVIEW: This review summarizes our current understanding of the role of gonadotropin-releasing hormone (GnRH)/GnRH receptor (GnRHR) signaling at the maternal-fetal interface. RECENT FINDINGS: Several isoforms of GnRH and GnRHR are described. The hypothalamic decapeptide, GnRH-I, binds to the anterior pituitary and induces the synthesis and secretion of luteinizing hormone and follicle-stimulating hormone. It is also found in extrahypothalamic sites. A second isoform, GnRH-II, acts both in the hypothalamus and other organ systems, including placenta, breast, endometrium, and ovary. Although several putative isoforms of GnRHR have been identified, it is clear that, in humans, both GnRH-I and GnRH-II signal through a single receptor, GnRHR-I. GnRH-I, GnRH-II, and GnRHR-I mRNA and protein have been identified in placenta and regulate the ß-subunit of human chorionic gonadotropin production, which is essential for the maintenance of early pregnancy. They may also play a role in the autocrine/paracrine regulation of trophoblast invasion through extracellular matrix remodeling. SUMMARY: GnRH-I and GnRH-II have multiple extrapituitary roles. In placenta, they bind to GnRHR-I to stimulate the production of ß-subunit of human chorionic gonadotropin. They may also play a role in trophoblast invasion. A better understanding of the molecular mechanisms involved in GnRH/GnRHR signaling at the maternal-fetal interface may identify novel roles for GnRH agonists/antagonists in the prevention or treatment of hormonally mediated diseases.
