Multimodal Prehabilitation for Gynecologic Cancer Surgery.

Surgical treatment is commonly employed to treat patients with gynecologic cancer, although surgery itself may function as a stressor, reducing the patients' functional capacity and recovery. Prehabilitation programs attempt to improve patients' overall health and baseline function prior to surgery, thereby enhancing recovery and lowering morbidity. In recent years, prehabilitation has come to primarily refer to multimodal programs that combine physical activity, nutritional support, psychological well-being, and other medical interventions.

Clinical relevance of vaginal natural orifice transluminal endoscopic surgery (vNOTES) in gynecology.

This study reviews the progress and recent advances in vaginal natural orifice transluminal endoscopic surgery (vNOTES) as a minimally invasive gynecologic procedure. The proposed advantages of vaginal natural orifice transluminal surgery include enhanced cosmesis due to a scarless procedure, better exposure compared with the pure vaginal approach, tolerable pain scores, fewer perioperative complications, and a shorter hospital stay. Recent advances in surgical instrumentation and technology have improved the feasibility of vNOTES as an innovative treatment option for gynecological conditions.

Effect and Safety of Diluted Vasopressin Injection for Bleeding Control During Robot-assisted Laparoscopic Myomectomy in Reproductive Women With Uterine Fibroids: A Randomized Controlled Pilot Trial (VALENTINE Trial).

Background/aim: Vasopressin injected during myomectomy is known to effectively reduce bleeding but is sometimes associated with intraoperative vasoconstriction and hypertension due to systemic absorption. Although there is a growing preference for the use of diluted vasopressin, evidence of its effect and safety is still lacking.

Patients And Methods: We performed a randomized controlled pilot trial to evaluate the effect and safety of vasopressin diluted in a constant volume during robot-assisted laparoscopic myomectomy (RALM), where a total of 39 women with uterine fibroids were randomly assigned into the following three groups (group 1, 0.

Effect and safety of diluted vasopressin injection on bleeding during robot-assisted laparoscopic myomectomy: a protocol for a randomised controlled pilot trial.

Introduction: Even though the injection of diluted vasopressin into the uterus is expected to reduce intraoperative bleeding with decreased adverse effects during robot-assisted laparoscopic myomectomy (RALM), there is a lack of relevant trials to show its effect and safety. Thus, this study was designed to compare the effect and safety of vasopressin injection on bleedings based on dilution levels of vasopressin with constant volumes during RALM.

Methods And Analysis: This is a randomised controlled pilot trial, where a total of 39 patients will be randomly divided into three experimental groups in a 1:1:1 ratio.

Is increased chronological age a contraindication to debulking surgery for elderly patients with advanced ovarian cancer?

Objective: This study aimed to identify the impact of care and change in the consultation process given by a gynecologic hospitalist on patient waiting time in the emergency department (ED).

Materials And Methods: This is a pre-post study that compared patients' length of stay at the ED ten months before and after intervention by the gynecologic hospitalist in 2018. The consultation process changed from ED staff contacting the gynecologic resident (pre-intervention group) to directly contacting the gynecologic hospitalist (post-intervention group).

Solution to prevent tumor spillage in minimally invasive radical hysterectomy using the endoscopic stapler for treating early-stage cervical cancer: Surgical technique with video.

Gynecologic oncologists had originally preferred minimally invasive surgery (MIS) over laparotomic surgery for patients with early-stage cervical cancer until the Laparoscopic Approach to Cervical Cancer (LACC) trial reported a worse prognosis and more loco-regional recurrence in patients treated with MIS. Although some controversy remains, experts suggested that tumor cell spillage and aggravation may have been caused by intra-corporeal colpotomy, usage of uterine elevators, maintenance of Trendelenburg position, and tumor irritation by capnoperitoneum during surgery. Thus, we introduce a surgical procedure with some steps added to the conventional MIS radical hysterectomy for preventing tumor spillage during the surgery, which is currently being evaluated in terms of safety and efficacy through a prospective, multicenter, single-arm, phase II study, entitled "Safety of laparoscopic or robotic radical surgery using endoscopic stapler for inhibiting tumor spillage of cervical neoplasms (SOLUTION trial: NCT04370496)".

Expression Is Associated With Prognosis of High-grade Serous and Clear Cell Carcinoma of the Ovary.

Background/aim: To evaluate the role of serine protease inhibitor B11 (SERPINB11) expression as a prognostic biomarker in high-grade serous carcinoma (HGSC) and clear cell carcinoma of the ovary (CCC).

Materials And Methods: We obtained tumor tissues from patients with HGSC (n=145) and CCC (n=59). We evaluated immunohistochemically the expression of SERPINB11 and investigated whether SERPINB11 expression affects platinum-resistance and the prognosis of HGSC and CCC.

Comparison of Vaginal Natural Orifice Transluminal Endoscopic Surgery (vNOTES) and Laparoendoscopic Single-Site (LESS) Hysterectomy on Postoperative Pain Reduction: A Randomized Pilot Study.

Introduction: Vaginal natural orifice transluminal endoscopic surgery (vNOTES) hysterectomy has shown benefit in postoperative pain and operation time compared to laparoscopic hysterectomy in recent studies. However, no prospective studies comparing laparoendoscopic single-site (LESS) and vNOTES hysterectomy have been performed. This study aims to evaluate postoperative pain and safety of vNOTES hysterectomy compared to LESS hysterectomy for benign uterine disease.

Preservation of the ovarian reserve and hemostasis during laparoscopic ovarian cystectomy by a hemostatic agent versus suturing for patients with ovarian endometriosis: study protocol for randomized controlled, non-inferiority trial (PRAHA-2 trial).

Background: Endometriosis (EMS) can be implanted everywhere, especially in pelvic organs. EMS can be asymptomatic, but it can result in pelvic pain and infertility by inducing local inflammation and pelvic adhesion. The prevalence of EMS is about 10% in reproductive-age women and higher in women with pelvic pain or infertility.

Efficacy and safety of intravenous administration of high-dose selenium for preventing chemotherapy-induced peripheral neuropathy in platinum-sensitive recurrent ovarian, fallopian or primary peritoneal cancer: study protocol for a phase III, double-blind, randomized study.

Background: The second-line chemotherapy using paclitaxel, carboplatin, and bevacizumab for treating platinum-sensitive recurrent ovarian, fallopian or primary peritoneal cancer frequently cause chemotherapy-induced peripheral neuropathy (CIPN), which is significantly associated with deterioration of quality of life. Despite the potential of some agents to prevent and treat CIPN, and there is still a lack of evidence of the effect. Although selenium has been suggested as an antioxidant candidate to prevent CIPN, there are insufficient data regarding its effect due to its low dose by oral administration.
