Navigational systems are paramount in solving today's traffic dilemmas, and have important applications in the human body. Current imaging must be diagnostic and is often dictated by the radiologist, but it is up to the surgeon to consider surgical procedures and to decide in which case surgical navigation (SN) has advantages. Knowledge of the surgical capabilities of SN is indispensable. The aims of this article are to support real-time image-guided SN, present routine and advanced cases with precise preoperative planning, and show the scientific capabilities of SN.

Background: Robot-assisted vitreoretinal surgery makes it easier for the surgeons to perform precise and dexterous manipulations required in vitreoretinal procedures.
Methods: We systematically evaluated manual surgery, conventional two-hand teleoperation, a novel one-hand teleoperation, and automation in a needle positioning task using a realistic surgical eye model, measuring the expert surgeon's performances and the novice's learning curves.
Results: The proposed one-hand teleoperation improved the positioning accuracy of expert surgeons , enabled novices to achieve a consistent accuracy more quickly , decreased the novice's workload more quickly , and made it easier for novices to learn to conduct the task quickly .

Hilar Cholangiocarcinoma (h-CCA) originates from the epithelial cells, which characters as longitudinal growth along the bile ducts and invasion of peripheral vascular nerves. Due to the tumours insidious progression and usually become advanced stage disease at presentation, patients' mortality could parallel incidence rates. For patients who are not amenable to resection, systemic therapy and palliative treatment become the way to go.

: Diabetes mellitus (DM) is associated with worse surgical outcomes, and is a risk factor for bladder cancer and subsequent oncological outcomes. This study evaluated outcomes robot-assisted radical cystectomy (RARC) compared to open radical cystectomy (ORC) in patients with DM. : Data of adults ≥ 18 years old with DM who underwent radical cystectomy were extracted from the United States National Inpatient Sample database 2005-2018.

Stereotactic systems have traditionally used Cartesian coordinate combined with linear algebraic mathematical models to navigate the brain. Previously, the development of a novel stereotactic system allowed for improved patient comfort, reduced size, and carried through a simplified interface for surgeons. The system was designed with a work envelope and trajectory range optimized for deep brain stimulation applications only.
