Clinical Feasibility and Technical Aspects of Single Port Robotic TransAnal Minimally Invasive Surgery (SP-rTAMIS) for Rectal Neoplasm.
Int J Med Robot
February 2025
Division of Colorectal Surgery, Department of Surgery, Seoul St. Mary's Hospital, The Catholic University of Korea, Seoul, Korea.
Background: Single port robotic platform offers articulation and 360° camera rotation for anorectal tumour excision in a narrow pelvic space. This study assesses the clinical usefulness and outcomes of SP robotic transanal surgery.
Methods: Nine patients who underwent transanal excision using the SP robotic platform were included.
Robot-Assisted Laparoscopic Sacrohysteropexy with Autologous Fascia Lata.

Introduction And Hypothesis: Autologous fascia lata has been increasingly utilised in pelvic floor reconstructive surgeries such as sacrocolpopexy and sacrohysteropexy. This case highlights sacrohysteropexy with autologous fascia lata as a promising option for women with advanced uterovaginal prolapse who wish to preserve their uterus and avoid synthetic mesh.
Methods: We report the case of a 65-year-old woman with stage 3 pelvic organ prolapse following one forceps and one spontaneous vaginal delivery.
Development of a Self-Deploying Extra-Aortic Compression Device for Medium-Term Hemodynamic Stabilization: A Feasibility Study.

Hemodynamic stabilization is crucial in managing acute cardiac events, where compromised blood flow can lead to severe complications and increased mortality. Conditions like decompensated heart failure (HF) and cardiogenic shock require rapid and effective hemodynamic support. Current mechanical assistive devices, such as intra-aortic balloon pumps (IABP) and extracorporeal membrane oxygenation (ECMO), offer temporary stabilization but are limited to short-term use due to risks associated with prolonged blood contact.

To achieve high-performance trajectory tracking for a manipulator, this study proposes a novel sliding mode control strategy incorporating a nonlinear disturbance observer. The observer is designed to estimate unknown models in real-time, enabling feedforward compensation for various uncertainties such as modeling errors, joint friction, and external torque disturbances. The control law is formulated by integrating the Backstepping method, Lyapunov theory, and global fast terminal sliding mode theory, ensuring global convergence to zero within finite time and enhancing system robustness.

The advantage of robot-assisted surgery (RAS) is its ability to perform fine surgical operations with higher-resolution images. RAS should be particularly beneficial for small children, but it requires a certain amount of working space. The da Vinci Surgical System instructions state that careful consideration of indications for robotic surgery in patients weighing ≤ 10 kg is required.
