Use of Indocyanine Green to Evaluate Ovarian Perfusion After Laparoscopic Detorsion. A Step-By-Step Demonstration Video.

OBJECTIVE: Demonstrate the usefulness of using indocyanine green after laparoscopic ovarian detorsion to save the ovary. DESIGN: A step-by-step video demonstration of a surgical technique. SETTING: Ovarian torsion is one of the most common gynecological emergencies, mainly affecting patients younger than 20 years of age [1], and causes 2% to 7% of acute abdomens [2]. It is not advisable to routinely perform ovariectomy even with a necrotic ovary appearance [1]. Furthermore only in a small percentage of cases (16%) necrosis has been confirmed histologically [2]. Some studies have demonstrated that using indocyanine green to evaluate ovarian perfusion is inexpensive, low risk, and easily reproducible [3-5]. INTERVENTIONS: A 17-year-old patient was referred to our hospital for acute abdominal pain. Ultrasound revealed ovarian torsion; therefore, the patient underwent surgical treatment. During laparoscopy, the presence of a right ovarian torsion was confirmed. A lesion compatible with a hemorrhagic corpus luteum of 6 cm was present on the ovary affected. Before ovarian detorsion, indocyanine green was administered intravenously at a 0.5 mg/kg dose. The first aspect noted was the total lack of ovarian vascularization; then ovarian detorsion was performed. At this point, using technology of Rubina (KARL STORZ SE & Co. KG, Tuttlingen, Germany), it was possible to highlight the progressive ovarian revascularization. Ovarian reperfusion occurred starting from the ovarian hilum and ending at the periphery. We proceeded with enucleation of the hemorrhagic corpus luteum by stripping technique, with subsequent ovarian reconstruction with continuous 2-0 monofilament suture. Finally, we fixed the ovary to the stump of the right round ligament. The final view highlights good ovarian vascularization. No complications occurred; the patient was discharged on the first postoperative day. A 6-month follow-up ultrasound confirmed the recovery of the vascularization of ovary. CONCLUSION: Using indocyanine green represents a valid option to evaluate ovarian perfusion after detorsion. It could help the surgeon decide to save the ovary and thus allow fertility-sparing surgery in more cases.

A Systematic Review of the Guidelines on Venous Thromboembolism Prophylaxis in Gynecologic Oncology.

(1) Background: This review aimed to summarize the indications for venous thromboembolic (VTE) events' prophylaxis in a gynecological cancer population, according to the most recent guidelines. (2) Methods: A systematic review of the guidelines in PubMed, SCOPUS, Web of Science, EMBASE, and CINHAL regarding VTE prevention in gynecological cancer patients was conducted according to PRISMA criteria. We compared the recommendations given by oncological and hematological societies regarding VTE prevention in gynecological cancer patients published from January 2010 through March 2021. We searched for the following keywords: "venous thromboembolism prevention", "cancer", and "guidelines". The AGREE II checklist was used to critically analyze the guidelines' quality. (3) Results: There were 1003 documents available; 14 met the inclusion criteria, 5 were excluded and, eventually, the guidelines of 10 societies were evaluated. (4) Conclusions: The guidelines agree that low-molecular-weight heparin (LMWH) and fondaparinux achieve better results in VTE prevention in gynecological cancer patients. Direct oral anticoagulants (DOACs) can be used to prevent VTE in outpatients and high-risk medical patients after discharge. VTE risk scores should be applied to all oncological patients to identify those who would benefit from a prevention program. More attention should be paid to mechanical prophylactic methods due to the high bleeding risk of gynecological cancer patients.

Hysteroscopic Treatment of Cervical Pregnancy: A Scoping Review of the Literature.

OBJECTIVE: Many therapies have been proposed for cervical pregnancy (CP) treatment; however, there is no consensus on the best practice to adopt, mainly owing to the rarity of this condition and the lack of randomized controlled trials. Therefore, there are no clinical practice guidelines for the management of this patient set. We presented an English literature review about the hysteroscopic management of CP. DATA SOURCES: The literature review was performed according to the Preferred Reporting Items for Scoping Reviews. The search strategy aimed at identifying cases from the first patients tracked down to those diagnosed in May of 2021. We searched in PubMed, Scopus, Google Scholar, and MEDLINE databases. Mesh terms used included "Cervical Pregnancy," "Hysteroscopy," "Ectopic pregnancy," and "Resectoscopy." METHOD OF STUDY SELECTION: Case reports of randomized controlled trials, prospective controlled studies, prospective cohort studies, retrospective studies, case series, and case reports were considered eligible. Review, Letters to the Editor, and abstracts accepted at conferences were ruled out. TABULATION, INTEGRATION, AND RESULTS: We found a total of 3572 articles in all analyzed databases. A total of 2480 articles viewed were duplicated and therefore ruled out. After screening and excluding nonpertinent articles, 109 were assessed for eligibility, and 19 were included in the analysis. All articles were single case reports, small case series with no criteria selection, randomization, or study planning. We classified them as follows: cases treated with 10 mm resectoscope, with or without pretreatments of previous CP hysteroscopic approach, and cases resolved with 5 mm hysteroscopy, with or without pretreatments of previous CP hysteroscopic approach. CONCLUSION: The hysteroscopic method represents a feasible and safe approach to the CP treatment, although there are still some aspects to be clarified, such as the pretreatment need and the instruments' type and sizes based on the beta-subunit of human chorionic gonadotropin, pregnancy age, and dimension.

"Nerve-sparing" laparoscopic treatment of parametrial ectopic pregnancy.

OBJECTIVE: To demonstrate laparoscopic surgical management of parametrial ectopic pregnancy. DESIGN: Video presentation of laparoscopic nerve-sparing treatment of parametrial pregnancy. SETTING: Tertiary university center. PATIENT(S): A 33-year-old patient, nullipara at 8 weeks of gestation, with no comorbidity and no previous surgery, was admitted to a spoke hospital for acute abdominal pain. During hospitalization, a transvaginal gynecologic ultrasound revealed pregnancy with ectopic localization. Free pelvic fluid was detected, and a subsequent diagnostic laparoscopy was performed because of worsening symptoms. During the procedure, hemoperitoneum drainage was instituted and American Society of Reproductive Medicine stage III pelvic endometriosis was diagnosed. A round formation approximately 3 cm in diameter was found at the left posterior parametrium (Fig. 1). Due to the pregnancy position and ß-human chorionic gonadotropic (ß-hCG; 820 mUI /mL) values, conservative treatment was chosen. Thus, methotrexate at 50 mg/m2 body surface area was administered. A second dose of methotrexate was administered seven days after the first one, and the ß-hCG increased to 1068 mUI. On day 14 after treatment, the ß-hCG was 1053 mUI/mL. Therefore, surgical treatment was chosen, and the patient was transferred to our center. An ultrasound assessment confirmed the ectopic pregnancy with a live fetus in the left posterior parametrium. INTERVENTION(S): The patient underwent operative laparoscopy to remove the ectopic pregnancy. Surgery was performed using a 3-dimensional optical system (TIPCAM 1, S D3-LINK; Karl Storz SE & Co., Tuttlingen, Germany). After drainage of the hemoperitoneum, the gestational sac was identified in the left posterior parametrium. The uterus, tubes, and ovaries showed normal morphology. Pelvic endometriosis was confirmed. After accessing the left pelvic retroperitoneum with the medial and lateral pararectal spaces' opening and development, ipsilateral ureterolysis was necessary to isolate the parametrial pregnancy in close contact with it. Coagulation and sectioning of the deep uterine veins were essential to control hemostasis. Identification of the left hypogastric nerve, which was partially infiltrated by the chorionic villi, and the pelvic splanchnic nerves, was required to safeguard them (Fig. 2). Subsequently, the surgeon decided to place a ureteral stent to prevent urologic complications. MAIN OUTCOME MEASURE(S): The laparoscopic approach proved to be safe and feasible to manage parametrial pregnancy. RESULT(S): The pregnancy was removed entirely. The patient was discharged 72 hours after the procedure with an uneventful postoperative course. The histologic report confirmed the diagnosis of parametrial pregnancy on decidualized endometriotic tissue. The ß-hCG serum level became negative in 20 days. CONCLUSION(S): Extrauterine pregnancies represent one of the leading causes of maternal death in the first trimester and constitute approximately 1%-2% of total pregnancies. Of these percentages, only 5%-8.3% are nontubal. Cases of abdominal pregnancy are even rarer, estimated at <1%, and among these, according to a recent review, only 20 cases of retroperitoneal pregnancy were described in the literature. The intraoperative finding of multiple endometriotic implants on the parietal peritoneum above the retroperitoneal pregnancy, together with the decidualized endometriosis result of the histologic examination have been considered to explain the pathogenesis of the condition. It is plausible to suppose that endometriosis has represented the access route for the fertilized ovum, which implanted on endometriotic superficial tissue and then moved toward the retroperitoneal vascularized structures. The diagnosis and treatment are challenging for the gynecologist. Medical treatment is a valid approach to uninterrupted early ectopic pregnancies; however, symptomatic patients' medical therapy failure is one indication for a surgical procedure. The laparoscopic method is optimal, especially in cases like the reported one, in which minimally-invasive techniques allowed complete removal of the pregnancy, respecting the anatomic structures of the retroperitoneum using nerve-sparing techniques. Furthermore, it ensured a safe ureteral stent placement without imaging. The laparoscopic surgical approach can be a safe and feasible option. It allows an early discharge, with a minimum risk of dysfunctional complications, and improves life quality compared to more destructive interventions. In conclusion, to control vascular, nervous, and urinary tract structures, surgical treatment should be based on anatomic knowledge of retroperitoneal anatomy to guarantee the best surgical outcome.

The Rare, Unexpected Condition of a Twisted Leiomyoma in Mayer-Rokitansky-Küster-Hauser (MRKH) Syndrome: Etiopathogenesis, Diagnosis and Management. Our Experience and Narrative Review of the Literature.

Uterine leiomyomas are a common finding in medical practice, but their frequency changes drastically when contextualized in a syndrome, as in the following case. A 50-year-old woman with a known Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome presented at our clinic with abdominal pain located in the lower quadrants and scarcely responsive to analgesic therapy. A twisted gynecological pelvic mass was diagnosed, and management for prompt resolution was adopted. Histologically the mass was described as a leiomyoma. The aim of the present study is to share our experience and to review the literature to compare different manifestation of the disease and different approach used in the various centers. The additional novelty of the paper is the immunohistochemical study we carried out on the leiomyoma that is contrasted with the current etiopathogenetic theories.

Interstitial Fluid in Gynecologic Tumors and Its Possible Application in the Clinical Practice.

Gynecologic cancers are an important cause of worldwide mortality. The interstitium consists of solid and fluid phases, situated between the blood vessels and cells. The interstitial fluid (IF), or fluid phase, is an extracellular fluid bathing and surrounding the tissue cells. The TIF (tumor interstitial fluid) is a dynamic fluid rich in lipids, proteins and enzyme-derived substances. The molecules found in the IF may be associated with pathological changes in tissues leading to cancer growth and metastatization. Proteomic techniques have allowed an extensive study of the composition of the TIF as a source of biomarkers for gynecologic cancers. In our review, we analyze the composition of the TIF, its formation process, the sampling methods, the consequences of its accumulation and the proteomic analyses performed, that make TIF valuable for monitoring different types of cancers.
