Study Objective: To compare 2 different types of uterine manipulators (i.e., tight fitting vs loose fitting) used for total laparoscopic hysterectomy (TLH).

Design: A randomized controlled trial. The primary end points were time for colpotomy, time from skin incision to detachment of the uterus, and histologic assessment of thermal damage to the vagina (Canadian Task Force classification I).

Setting: A university teaching hospital.

Patients: All consecutive women scheduled for TLH from May 2014 to December 2015. Patients were excluded if pregnancy or malignancy was suspected or uterine size exceeded 20 weeks' gestation.

Interventions: Patients were randomized to undergo TLH with 1 of the following uterine manipulators: (1) Colpo-Probe Vaginal Fornix Delineator (Cooper Surgical, Inc, Trumbull, CT) or (2) Hohl manipulator (KARL STORZ AG, Tuttlingen, Germany).

Measurements And Main Results: A total of 91 patients, 49 in the Hohl manipulator group and 42 in the Colpo-Probe group, were included in the final analysis. There was no difference in patient characteristics, uterine weight, or estimated blood loss. The median time for insertion of the manipulator (2 minutes [interquartile range (IQR), 2-5 minutes] vs 6 minutes [IQR, 5-7], p < .001), the median time from skin incision to detachment of the uterus (55 minutes [IQR, 41-70] vs 65 minutes [IQR, 58-79], p = .004), and the median time for colpotomy (7 minutes [IQR, 5-10] vs 12 [IQR, 8-17], p < .001) were shorter with the Hohl manipulator. Thermal damage to the vagina varied greatly and ranged from 32 μm to 5232 μm but was not significantly different between groups (median maximum thermal damage = 1043 μm [IQR, 682-1934] vs 1522 μm [IQR, 884-2144], p = .211).

Conclusion: Use of the Hohl manipulator results in a shorter operative time from skin incision to detachment of the uterus during TLH. Although the colpotomy time is shorter using the Hohl manipulator, this did not translate to less thermal damage to the vaginal cuff. Further studies comparing uterine manipulators are warranted to find the optimal instrument for ease of surgery and decreased thermal spread.

MicroRNAs (miRNAs) emerge as critical regulators of CD8 + T cell function within the complex tumor microenvironment (TME). This review explores the multifaceted interplay between miRNAs and CD8 + T cells across various cancers. We discuss how specific miRNAs influence CD8 + T cell activation, recruitment, infiltration, and effector function.

Introduction: The three-arm approach is mainly selected, despite the multiple robotic arms in da Vinci Xi. This type of surgical setup may provide less autonomy to the console surgeon and result in greater dependence on the bedside surgical assistant. Therefore, the 4th arm is used instead of the assist port, which is why we developed "pure" robot simple hysterectomy (PRSH) as a novel surgical technique, in which all ports are operated by robotic arms.

Oncologic Outcomes of Laparoscopic Radical Hysterectomy Incorporating Modified Tumor-Free Techniques.

Obstet Gynecol

December 2024

National Clinical Research Center for Obstetric & Gynecologic Diseases, Department of Obstetrics and Gynecology, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences & Peking Union Medical College, Beijing, China.

Article Synopsis
  • The study aimed to determine if modified tumor-free techniques in laparoscopic radical hysterectomy improve outcomes for early-stage cervical cancer patients.
  • Patients who underwent the modified technique had shorter hospital stays and significantly lower recurrence rates compared to those who had conventional surgery.
  • The findings suggest that modified tumor-free laparoscopic hysterectomy is a viable option, leading to better disease-free survival rates in this patient population.

Multiple hour antifibrotic drug release enabled by a thermosensitive quadpolymer.

Int J Pharm

Article Synopsis
  • The study focuses on an innovative thermosensitive quadpolymer designed for injection to deliver anti-fibrotic drugs, specifically targeting uterine fibroids while potentially preserving fertility.
  • The quadpolymer functions as an injectable solution at room temperature and transforms into a stable gel at body temperature, allowing for sustained release of the drug pirfenidone.
  • Results showed that the pirfenidone-loaded quadpolymer effectively inhibited fibroid cell proliferation, indicating its potential as a localized treatment option for uterine fibroid therapy.

Uterine fibroids are benign tumors, arising from uterine smooth muscle cells. They are one of the most common benign tumors of the female genital tract among childbearing women, occurring in 20%-50% of women of reproductive age. The association of uterine myomas with pregnancy is high.
