Objectives: To report the first cases of surgical staging for apparently early-stage endometrial cancer performed using the Versius® next-generation robotic surgical system (Cambridge Medical Robots [CMR] Surgical, Cambridge, UK).

Design: Prospective case series. Participants/Materials: Women who underwent surgical staging, including total hysterectomy, bilateral adnexectomy, and sentinel lymph node (SLN) biopsy, for apparently early-stage endometrial cancer using the Versius® next-generation robotic surgical system (CMR Surgical, Cambridge, UK).

Background: The optimal duration of second stage of labor has been largely discussed in literature, but there are no uniformly accepted contemporary criteria for defining normal or abnormal length. Available evidence suggests that longer duration of second stage of labor is associated with a lower rate of spontaneous vaginal delivery and increased maternal morbidity. On the neonatal side, it seems that longer second stage doesn't affect new-born morbidity, in a context of very rare neonatal complications.

Background: The intrauterine manipulator used during a hysterectomy for endometrial cancer has been suggested as a reason for worsening oncologic outcomes. However, only a few non-randomized retrospective studies have investigated this association.

Primary Objectives: To compare 4-year recurrence-free survival in the group of patients who undergo hysterectomy using an intrauterine manipulator with that of those who undergo hysterectomy without it.

Article Synopsis
  • The study aimed to evaluate the effectiveness of different classification systems for predicting the behavior of uterine Perivascular Epithelioid Cell tumors (PEComas), including Folpe, modified Folpe, Bennet, and Schoolmester.
  • Researchers reviewed pathology records and conducted a systematic literature review, collecting data from 101 identified cases of uterine PEComas treated at their center and elsewhere, while excluding cases linked to tuberous sclerosis complex.
  • The modified Folpe classification was found to be the most reliable for predicting tumor behavior, suggesting that adjustments to size and mitotic figure thresholds could enhance predictions related to patient mortality.

Background: Previous reviews on hysterectomy versus uterine-sparing surgery in pelvic organ prolapse (POP) repair did not consider that the open abdominal approach or transvaginal mesh use have been largely abandoned.

Objectives: To provide up-to-date evidence by examining only studies investigating techniques currently in use for POP repair.

Search Strategy: MEDLINE and Embase databases were searched from inception to January 2023.

Purpose: To compare conventional bipolar electrosurgery with advanced bipolar vessel sealing (ABVS) devices for total laparoscopic hysterectomy (TLH).

Methods: A systematic review was conducted by searching Scopus, PubMed/MEDLINE, ScienceDirect, and Cochrane Library from January 1989 to November 2021. We identified all studies comparing ABVS devices with conventional bipolar electrosurgery in TLH and reporting at least one of the following outcomes: total blood loss, total operative time, hospital stay, perioperative complications, or costs.

Article Synopsis
  • Oncovascular surgery, which involves removing major blood vessels affected by cancer, is crucial for achieving complete removal of tumors in advanced ovarian cancer patients.
  • A review of patient cases at Verona University showed that five patients had successful major vascular resections, with all having preoperative identification of vascular involvement and obtaining R0 status (no visible cancer remaining).
  • The literature review found a total of 12 cases of major vessel resections in ovarian cancer, with a notable percentage experiencing postoperative complications, yet a majority remained disease-free at their last follow-up.

Objective: This study aimed to assess the effects on oncologic outcomes of intrauterine manipulator use during laparoscopic hysterectomy for endometrial cancer.

Data Sources: A systematic literature search was performed by an expert librarian in multiple electronic databases from inception to January 31, 2023.

Study Eligibility Criteria: We included all studies in the English language that compared oncologic outcomes (recurrence-free, cause-specific, or overall survival) between endometrial cancer patients who underwent total laparoscopic or robotic hysterectomy for endometrial cancer with vs without the use of an intrauterine manipulator.

There is evidence that diet and nutrition are modifiable risk factors for several cancers. In recent years, attention paid to micronutrients in gynecology has increased, especially regarding Human papillomavirus (HPV) infection. We performed a review of the literature up until December 2022, aiming to clarify the effects of micronutrients, minerals, and vitamins on the history of HPV infection and the development of cervical cancer.

Total hysterectomy and bilateral adnexectomy is the standard treatment for atypical endometrial hyperplasia and early-stage endometrial cancer. However, the recommended surgical treatment precludes future pregnancy when these conditions are diagnosed in women in their fertile age. In these patients, fertility-sparing treatment may be feasible if the desire for childbearing is consistent and specific conditions are present.

Sentinel lymph node (SLN) biopsy in apparent early-stage ovarian cancer may spare the surgical staging with extensive retroperitoneal dissection and its associated morbidity. However, SLN biopsy in ovarian cancer is still experimental and under investigation. A 46-year-old post-menopausal woman with bilateral apparent stage IC1 endometrioid ovarian cancer underwent surgical staging by SLN biopsy and subsequent comprehensive laparoscopic pelvic and -aortic lymphadenectomy.

Purpose: To compare the effects of epidural analgesia (EA) and combined spinal epidural analgesia (SEA) on labor and maternal-fetal outcomes.

Methods: We retrospectively identified and included 1499 patients with a single cephalic fetus who delivered at the study center from January 2015 to December 2018 and received neuraxial analgesia at the beginning of the active phase of labor (presence of regular painful contractions and cervical dilatation between 4 and 6 cm). Data including analgesia, labor characteristics, and maternal-fetal outcomes were retrieved from the prospectively collected delivery room database and medical records.

Objective: In gynecologic oncology, the consolidated injection site for the pelvic sentinel lymph node mapping is the cervix. However, in apparent early-stage ovarian cancer, current trials map the pelvic area injecting the tracers in the utero-ovarian ligament. A different injection site is proposed based on a possible different lymphatic ovarian drainage through the utero-ovarian ligament and uterus and consequently a different pelvic sentinel lymph node mapping than the cervix; however, this was never proven.

The impact of Coronavirus disease 2019 pandemic on Italian Gynaecological Units practice and the compliance and satisfaction with available guidelines/recommendations is unknown. Therefore, a survey was conducted among all Italian Gynaecological Units Directors in April 2020. The response rate was 90% (135/150).

Introduction: The transfusion rate in hysterectomies for benign pathology is almost 3%. However, despite the strong interest in reducing intraoperative bleeding, limited evidence is available regarding the technical aspects concerning uterine vessel management during a total laparoscopic hysterectomy (TLH). Uterine artery (UA) closure in TLH can be performed at the origin from the internal iliac artery or at the uterus level (UL).

Objective: Vaginal cuff dehiscence, a severe and potentially detrimental complication, has significantly increased after the introduction of endoscopic hysterectomy. The aim of this systematic review and meta-analysis of the available literature was to identify the incidence of, and possible strategies to prevent, this complication after total laparoscopic hysterectomy and total robotic hysterectomy.
